A Dust Collection Success Story at Cosmetics Group USA

Antecedentes

Cosmetic Group USA is an ever growing developer and manufacturer of cosmetics and skin care for national and international brands.

Cosmetics Group USA is a California-based maker of a range of beauty products, partnering with the world’s most well-known cosmetics brands. The process of cosmetics manufacturing begins with the careful blending of raw materials to create the desired formulations. These powders are then finely milled and sifted to achieve the right texture and consistency.

Scope of Work

As part of their plans to expand and upgrade their Los Angeles factory, Cosmetics Group leadership recognized two main issues with dust collection that needed to be addressed:

An efficient, central dust collection system with capacity to support planned operations and expansion in the factory.
The air pressure in the building required balancing, as the dust collection system generated significant negative pressure, resulting in slamming doors, potential dust and particulates being pulled into the building through windows and doors, and inefficient heating and cooling of the facility.

solución

To resolve these challenges, the company partnered with Baghouse.com to design and install a dust collection system that would satisfy their unique challenges.

“Our team worked efficiently to ensure the new dust collection system was up and running ahead of schedule, minimizing any disruptions to the Cosmetics Group’s operations” —said David Dal Santo, Systems Engineer for this project.

Baghouse.com developed a dust collection system using two 4-32 cartridge dust collectors with high-efficiency nano-media cartridge filters and twin 75 HP ground-mount fans. The various process dust pickup points in the lab and production areas were connected to the dust collectors via galvanized steel, clamp-together duct, an economical duct configuration that is perfect for lighter duty applications like cosmetic powder and dust.

“With high-efficiency nano-media cartridge filters and a robust ductwork design, we’re confident that this setup will exceed expectations for years to come” —said David Dal Santo.

Positioned on the clean air side of the unit, the HEPA after-filter acts as a secondary filtration stage, capturing even the tiniest microscopic particles before the air is returned to the facility.

To address the pressure balancing challenge, Baghouse.com designed the dust collection system exhaust to return to the building. Dual HEPA after-filter units were installed on the return air ductwork to meet compliance requirements and ensure the highest filtration efficiency for the filtered air that would be returned to the building. Baghouse.com also supplied and installed a central vacuum system with 30+ vacuum ports with flap valves for easy plug in of hoses where necessary.

In addition to the dust collection system sizing design, and delivery of the equipment, a Baghouse.com team installed the dust collection system and commissioned the units, successfully completing the project.

Conclusión

Baghouse.com developed a dust collection system using two 4-32 cartridge dust collectors with high-efficiency nano-media cartridge filters and twin 75 HP ground-mount fans. The various process dust pickup points in the lab and production areas were connected to the dust collectors via galvanized steel, clamp-together duct, an economical duct configuration that is perfect for lighter duty applications like cosmetic powder and dust.

Newly installed cartridge collectors, ductwork and HEPA After-Filters

“We were excited to take on this challenge and are thrilled with the outcome. Helping Cosmetics Group USA expand their operations while solving their dust collection issues was truly a rewarding experience” —said Matthew Coughlin, Engineer and Owner of Baghouse.com.

Happy with the results of their new dust collection system, Cosmetics Group USA continues to work with Baghouse.com to support additional future expansion plans for their factory.

Filtros de pliegues: ¡La solución más inteligente y económica!

Filtros tradicionales vs. filtros de pliegues

Los filtros tipo bolsa están hechos de distintos materiales y pueden usarse en aplicaciones con altas temperaturas, mucho polvo, materiales abrasivos, corrosivos o con mucha humedad.

Los filtros tradicionales (de bolsa o manga) han sido el estándar en colectores de polvo por casi 100 años, y todavía son los más usados en casi todas las industrias. Son tan populares, entre otras cosas, porque son simples y baratos.

Pero cuando llega el momento de cambiarlos, ¿realmente siguen siendo la opción más económica si tomamos en cuenta todos los costos? En muchos casos, la respuesta es no. Por eso, una alternativa que vale la pena considerar es cambiar tus filtros y jaulas tradicionales por filtros de pliegues. Filtros de plieges

En este artículo te vamos a explicar qué son los filtros de pliegues y por qué pueden ser una mejor opción que los filtros tradicionales.

¿Qué son los filtros de pliegues?

Los filtros con muchos pliegues en el material proporcionan una mayor superficie de tela en un área reducida, permitiendo mejorar la relación aire-tela en la misma área del filtro

Como una de las tecnologías más nuevas en la recolección de polvo industrial, los filtros de pliegues tienen un mejor diseño que las bolsas o mangas tradicionales porque incluyen más tela filtrante en menos espacio.

Otra ventaja es que, como son más cortos, queda más espacio libre entre los filtros y la parte de la tolva, lo que los mantiene alejados del flujo de aire sucio que entra. Eso ayuda a que se desgasten menos y que el polvo se libere mejor cuando se hace el pulso de limpieza.

traditional filter bags versus pleated filters

El menor largo de los filtros ayuda a reducir el desgaste que causan las partículas de polvo al chocar contra ellos y también hace que el aire entre más despacio, lo que mejora la limpieza del filtro cuando se activa el pulso de aire.

Además, los filtros plisados no necesitan jaulas, porque el filtro y la estructura están integrados en una sola pieza. Esto significa menos piezas por comprar, más fácil de almacenar, y más sencillo de instalar. También filtran mejor que los tradicionales y duran más, a veces hasta el doble. Estos filtros están diseñados para aguantar la carga de trabajo actual en plantas con alta producción, y en la mayoría de los colectores tipo pulse jet se pueden instalar sin necesidad de hacer modificaciones estructurales.

¿Por qué usar filtros de pliegues en lugar de bolsas y jaulas tradicionales?

Además de las ventajas técnicas, los filtros de pliegues también ofrecen beneficios económicos importantes. Pueden reducir los costos hasta en un 60%. ¿Cómo? Filtros de plieges

— Menos filtros en total:

Como estos Filtros de plieges tienen más superficie filtrante, se necesitan menos unidades para hacer el mismo trabajo.

La instalación puede tomar hasta un 50% menos de tiempo comparado con el cambio de los filtros tradicionales.

— Instalación más fácil y rápida:

Al haber menos filtros y ser de una sola pieza, se instalan más rápido. El cambio puede tomar hasta la mitad del tiempo comparado con los filtros tradicionales.

— Menor uso de aire comprimido:

Como filtran mejor el polvo, estos filtros de pliegue se limpian más fácil, se necesita menos aire comprimido durante el ciclo de limpieza.

— Mayor duración:

Al ser más cortos y activar el ciclo de limpieza menos veces, sufren menos desgaste. Esto hace que duren entre 25% y 75% más… ¡a veces hasta 2 o 3 veces más!

— Mejor rendimiento y más capacidad:

Estos filtros de pliegues pueden mejorar mucho el rendimiento del colector, bajar emisiones, reducir el uso de electricidad y aumentar la capacidad del sistema. En algunos casos, se puede meter hasta 700% más tela filtrante en el mismo espacio.

Con esta capacidad extra, puedes elegir entre:

Mantener el mismo flujo de aire y alargar la vida útil de los filtros.
Aumentar el flujo de aire y usar un solo colector en lugar de varios, reduciendo costos operativos.

Conclusión: los filtros de pliegues ofrecen muchas ventajas (en la aplicación correcta)

what is cheaper: a filter bag or a pleated filter?

Los filtros tradicionales suelen ser los más baratos por unidad, pero con los filtros plisados el costo total —a corto y largo plazo— para reemplazar y mantener tu colector de polvo puede bajar muchísimo.

Aunque los filtros tradicionales suelen ser más baratos por unidad, los filtros de pliegues pueden ayudarte a ahorrar mucho más a corto y largo plazo, además de mejorar el funcionamiento del sistema. Filtros de plieges

Eso sí, no son recomendables en todos los casos. Por ejemplo, no se usan donde hay temperaturas muy altas o gases muy corrosivos. Sí existen versiones especiales para alta temperatura, pero son más caras y solo valen la pena si hay un beneficio económico claro al mejorar el rendimiento del colector.

En resumen: no solo te ayudan a ahorrar, sino que mejoran hasta la eficiencia y durabilidad. Los filtros de pliegue pueden marcar una gran diferencia en tu sistema de recolección de polvo.

Polvo peligroso: riesgos clave y soluciones prácticas para su gestión

How Harmful is Exposure to Dust in the Workplace?

In many industries, workers can be exposed to high levels of dust, causing breathing problems that could lead to life-threatening respiratory diseases. Most occupational lung diseases are caused by repeated, long-term exposure, but even a severe, single exposure to a hazardous agent can damage the lungs.

In What Industries is Dust a Hazard?

Manufacturing factories, processing facilities, and industrial sites all have the potential to emit dangerous dust.

Dust is a prevalent exposure at workplaces in various industries such as:

— Minería
— Foundries
— Chemical
— Food industries
— Stone working
— Woodwork

While many industries expose workers to dust, not all dust is equally harmful. Excessive exposure to some types of dust has been linked to the development of particular health problems, such as lung cancer or asthma. Different forms of the same substance may present different hazards. For example, a large piece of wood may be safe, but when ground into dust, it can become hazardous.

What Problems Can Exposure to Dust Lead To?

Exposure to any dust in excessive amounts can create respiratory problems. The harmful effects of dust can vary, from skin irritation to lung cancer, depending on the composition of the dust and the type and degree of exposure. Dust is not always an obvious hazard because the particles which cause the most damage are often invisible to the naked eye, and the health effects of exposure can take years to develop.

Safe Materials When Solid, Hazardous in Dust Form

As we mentioned, some materials that are generally safe in their solid form can become hazardous when they are ground into dust and inhaled over long periods. For example, Silica is found in materials like sand, stone, and concrete, silica is harmless in its solid state. However, when these materials are cut, ground, or drilled, they produce respirable crystalline silica dust. Prolonged exposure to this dust can lead to silicosis, a serious lung disease, as well as lung cancer and other respiratory issues.

Inherently Toxic Dusts

Other dusts are inherently toxic and should be avoided as much as possible due to their severe health risks:

— Heavy Metals: Dust from metals like lead, cadmium, and arsenic can be extremely toxic. Inhalation of these dusts can lead to serious health issues, including damage to the nervous system, kidneys, and other organs.
— Asbestos: Asbestos fibers, when inhaled, can cause severe lung diseases, including asbestosis, lung cancer, and mesothelioma. Even small amounts of asbestos dust can be dangerous.
— Ácidos minerales: Dusts from mineral acids, such as sulfuric acid, can cause severe respiratory and skin irritation.

How Can We Prevent Dust-Related Diseases?

PTFE filters from Baghouse.com can easily reach sub-micron filtration ranges. In some applications efficiencies are high enough to allow for the recirculation of treated air back into the facility.

In some applications, PTFE membrane filtration efficiencies are high enough to allow for the recirculation of treated air back into the facility.

In normal situations with non-hazardous materials, a simple dust collector with basic filters is often sufficient to meet regulatory requirements. However, when handling hazardous dust, additional steps are necessary to comply with local regulations. For example, hazardous dust might require dust collectors fitted with high-efficiency filters, such as bags or cartridges with nanofiber or PTFE membranes. These filters capture a higher percentage of the smallest particles.

Using HEPA Filters for Extra Safety

HEPA after-filter serves as a powerful ally when searching for cleaner indoor air quality, particularly in industrial settings

If the dust is particularly hazardous, local authorities or safety regulators may require an extra set of filters known as after-filters or HEPA (High-Efficiency Particulate Air) filters. These are usually placed after the primary filters, either before or after the fan. HEPA filters act as a fallback safety measure. In normal operation, the primary filters capture all the dust. However, if there’s a hole or damage to the primary filters, the HEPA filters will capture any escaping dust, preventing it from being released into the environment or recirculated back into the building.

Conclusión

This guide aims to promote safety by educating company owners, managers, environmental personnel and workers about the dangers of hazardous dust and advocating for effective prevention strategies. Remember, a little awareness and action can go a long way in keeping your team safe and healthy.

Caso de Estudio: Expansión en Sunshine Minting

Antecedentes

Sunshine Minting, a global supplier and processor of precious metals, was looking to upgrade their dust collection system to support new melt lines and future expansion. Their existing small collectors were inadequate for the increased capacity and airflow requirements.

Scope of Work

Sunshine Minting needed a dust collection solution with sufficient capacity and airflow to handle their expanding operations. Additionally, they required improvements in ductwork to connect both new and existing processes to the new system. A spark trap was necessary to mitigate the fire risk from sparks traveling through the ductwork into the collector. Additionally, flame resistant filters were used for extra protection.

solución

Baghouse.com responded to Sunshine Minting’s needs by dispatching a technician for an on-site inspection. The technician documented the facility layout, the proposed location for the new collector, and the new ductwork configuration. Following this, we installed an ACT 4-48 cartridge collector con a 20,000 CFM fan, a 50 HP motor, and a VFD control panel. A Boss Products Raptor Shield 22″ spark arrestor was also installed, along with connecting ductwork throughout the facility. The turnkey installation included programming of the VFD and airflow measurements to confirm adequate airflow and pressure at pickups and ducts.

What is a VFD?
It stands for Variable Frequency Drive, and is a type of fan controller. A VFD allows the user to run their dust collector fan at a lower or higher rate to manage performance. Rather than simply flipping a switch and running your fan at full speed (think 40kW per hour), the fan motor will run at a lower rate, saving significant energy costs in the long run.

Installation Challenges

Placing the new collector and fan without interfering with existing condensers and other equipment was a challenge. To overcome this, the inlet duct was routed up and over the area, and the fan exhaust was directed away from the facility as requested by the customer. These minor layout modifications are common and easily accomplished with a proper design and layout review.

Outcome

The installation of the modern cartridge-style collector has provided Sunshine Minting with sufficient fan and filter capacity for current processes, and extra capacity for future expansion. The VFD controller on the fan improves power efficiency and allows for easy adjustment to accommodate future changes. The MERV 15 rated nano media filters, upgraded with flame retardant treatment, ensure maximum safety from sparks or hot coals.

Sunshine Minting now enjoys enhanced dust collection efficiency and safety, with the system’s additional capacity supporting their ongoing and future operational growth. The improved power efficiency and safety features represent a significant upgrade from their previous setup.

Conclusión

Baghouse.com successfully addressed Sunshine Minting’s dust collection needs with a comprehensive solution that supports their expanded operations and future growth, enhancing both safety and efficiency in their facility.

Cómo medir tus filtros y jaulas de baghouse.

When ordering replacement baghouse bag filters, it is extremely important that you order the right size to ensure a proper fit in your baghouse.

Properly fitting bags and cages are integral to achieving long filter bag life and optimum baghouse performance. Filter bags come in a huge variety of sizes and types, to fit many makes and models of baghouses.

Measuring Filter Bags & Cages - Key Terms

Flat Width/Diameter

This is the most critical measurement, and the one people most often get wrong. As we need this size correct down to a ⅛”, it is not possible to measure the diameter of a loose bag accurately enough for ordering. For that reason, we instead rely on a flat width measurement, which we can then convert to an accurate diameter.

Largo

For top load pulse jet bags, the bag is the same length as the cage or just 1⁄2” longer. For bottom load pulse jets, where the top of the raw edge bag is folded over the top of the cage, we recommend 4” of overlap, but some OEMs recommend 2”.

Tubesheet Hole Size/Snap Band Size

Often the hardest dimension to confirm, a hole size measurement accurate down to 1/32” is required to ensure proper fit. For best results, measure the hole with calipers or check the OEM drawings for details. Alternatively, you can send a sample bag to confirm the tubesheet hole size or have us make a sample bag/cuff to test fit before releasing the entire order to production.

Size Draft/Accurate Specifications

While it is usually possible to rely on previous bag sizing when reordering, at times, there may be reason to reconfirm all bag and cage sizing choices. Over time, sloppy or copy errors can result in slight variances in sizing making their way into orders and company records. In this way, the original bag sizing can see a slight, but impactful creep over successive orders.

When we suspect this has happened, we may ask you to go back and provide us with the fundamental component sizing that dictates the overall bag and cage sizing. For top load pulse jet, reverse air, and many shaker units this is the tubesheet hole size. For bottom load pulse jets, and some reverse air/shaker units, it is the mounting hub/venturi.

Once we have this fundamental sizing information, we can then recommend the proper bag and cage sizing.

Bag/Cage Fit or “Pinch”

Filters that are too loose or too tight on the cages will severely limit collection efficiency and lead to premature failure. For most felt bag materials (polyester and aramid/nomex being the most common) we generally recommend ¼” to ½” of pinch, meaning the bag diameter is that much larger than the cage. Other specialty fabrics such fiberglass, P84, and fabrics with PTFE membrane applied to them may require tighter tolerances.

Number Cage Vertical Wires and Horizontal Ring Spacing

Proper care must be taken to ensure that the cage construction will properly support the filter bag as well as optimize cleaning and efficiencies. Most fabrics work well with using cages with 10, 12 or 14 vertical wires. However, some specialty fabrics such fiberglass, P84, and fabrics with PTFE membrane applied to them require the additional support of 20 wire cages and possibly tighter spacing on the horizontal rings.

Common Bag and Cage Size Combos

Below we have listed a few common sizes for pulse jet and reverse pulse systems in use today.

Top Load Style

—Bag: 6.25” x ¼” tubesheet hole, 5.875” diameter x 96”/120”/144” long, snap band top, disk bottom – Cage: 5.625” diameter x 96”/120/144” long, turned down flange top (with or without integral venturi), pan bottom, 12 vertical wires, horizontal rings on 8” centers
—Bag: 6.25” x ¼” tubesheet hole, 6” diameter x 96”/120”/144” long, snap band top, disk bottom – Cage: 5.75” diameter x 96”/120/144” long, turned down flange top (with or without integral venturi), pan bottom, 12 vertical wires, horizontal rings on 8” centers
—Bag: 5” x ¼” tubesheet hole, 4.625” diameter x 96”/120”/144” long, snap band top, disk bottom – Cage: 4.5” diameter x 96”/120/144” long, turned down flange top (with or without integral venturi), pan bottom, 12 vertical wires, horizontal rings on 8” centers

Bottom Load Style

—Bag: 5.865” diameter x 100”/124” long, raw top, disc bottom – Cage: 5.625” diameter x 96/120”” long, split collar top, pan bottom, 12 vertical wires, horizontal wires on 8” centers (Flex Kleen style bottom load)
—Bag: 4.625” diameter x 100”/124” long, raw top, disc bottom – Cage: 4.5” diameter x 96/120”” long, split collar top, pan bottom, 10 vertical wires, horizontal wires on 8” centers (Mikropul bottom load and “twistlok” style)

Measuring Filter Bags - Step-By-Step

Top Load, Snap Band Filter Bag

Use a tape measure or ruler and measure the width across the bag.

Flat width/Diameter

Lay the bag out on a table or floor, flatten it completely.
Use a tape measure or ruler and measure the width across the bag.

Longitud

Mide a lo largo de la costura que recorre la longitud de la bolsa. Comienza en el centro de la banda de sujeción y termina en la primera costura en la parte inferior de la bolsa.

Cage-to-Bag (Bag-to-Cage) fit

Should have ¼” to 3/8” pinch; the bottom of the bag should have about a thumbs width between the bottom of the cage and the disc bottom of the bag.

Top Load, Snap Band Filter Bag – Woven Fiberglass

Flat width: Flatten bag and measure width across.
Longitud: Mide a lo largo de la costura que recorre la longitud de la bolsa. Comienza en el centro de la banda de sujeción y termina en la primera costura en la parte inferior de la bolsa.
Cage-to-Bag (Bag-to-Cage) fit: Should have 1/8” or less pinch, but shouldn’t be stretched tight around the cage.

Top Load, Snap Band Filter Bag – Felt with membrane

Flat width: Flatten bag and measure width across.
Longitud: Mide a lo largo de la costura que recorre la longitud de la bolsa. Comienza en el centro de la banda de sujeción y termina en la primera costura en la parte inferior de la bolsa.
Cage-to-Bag (Bag-to-Cage) fit: Should have 1/8” or less pinch, but shouldn’t be stretched tight around cage.

Shaker style Filter Bag

Flat width: Flatten bag and measure width across.
Longitud: Measure along the seam running the length of the bag. Start at the end of the snap band to the end of the bag, not including the tail.
Length of the tail: Measure along the seam from the end of the bag to the end of the tail
Flat width of the tail: Flatten tail and measure width.
Determine if the tail is 3 ply or 4 ply by pinching the material and feeling for layers.
If there is a wear cuff at the snap band end of the bag, measure length and width.

Measuring Cages - Step-By-Step

Step one: Measure from top to bottom the full length of the cage.

Full length of the cage: Mide de arriba a abajo.

Mide el diámetro en el centro de la jaula, en el punto más ancho entre los cables. Idealmente, usar una cinta Pi para determinar la circunferencia proporcionará una medición exacta.

2. Diámetro: Mide el diámetro en el centro de la jaula, en el punto más ancho entre los cables. Idealmente, usar una cinta Pi para determinar la circunferencia proporcionará una medición exacta.

Be aware that some OEMs make the bottom pan slightly smaller than the cage body to make it easier to insert the cage into the bag. This is why you should always measure the diameter near the middle of the cage.

3. Bottom construction: Determina si la copa inferior está doblada o si los cables están soldados a la copa.

4. Number of rings: Cuenta el número de anillos.

5. Space between rings: Mide el espacio entre los anillos. Nota: el espacio entre el último anillo y la parte inferior de la copa puede ser diferente.

6. Number of vertical wires: Cuenta el número de alambres verticales que recorren la longitud de la jaula.

7. Material: Acero sin tratar, galvanizado, recubierto, acero inoxidable 304, o especifica si es otro material.

8. Determine the top construction of the cage:

- — If the top has a venturi, measure the length of the venturi.

- — If the top has a split top, measure the space between the groove in the split top and the end of the top

Measure across the center of the hole in a straight line from one edge to the opposite edge.

Another important measurement to have in mind when ordering filters or cages, is the size of the tube sheet hole where our filters will be placed. This will ensure there is a perfect seal, extending the life of the filters and not allowing dust to go through.

With a wide range of sizes and types available, it’s essential to select the right filter bags and cages to suit your specific dust collector model. Following these basic steps will help you make informed decisions when ordering replacements, ensuring smooth operation and extended filter bag life for your dust collection system.

Another option to find out the right size of your filters and cages is to send us a used filter or cage so we can measure it for you. Feel free to get in contact with us if you prefer this option and we will be happy to assist you.

Conceptos básicos sobre la colección de polvo

A Brief History of Dust Collectors

Dust collection began during the late 1800s Industrial Revolution in the US, spurred by the rise in manufacturing and the oil industry, which generated increased waste like sawdust, coal dust, and chemicals. This waste polluted the air near factories, leading to health concerns. To tackle this, dust collectors were invented.

The First Dust Collector

The first dust collector is subject to debate, with some attributing it to Wilhelm Beth for his filter-based design, while others credit John Finch for his Cyclone Dust Collector introduced around 1885. Cyclones became popular by 1900 for their effectiveness in collecting coarse dust, and they’re still used today. Operating on centrifugal force, cyclones create a vortex that separates dust from air, depositing it into a collector while letting filtered air out.

The Shaker Dust Collector

In the mid-1920s, a significant advancement in dust collection emerged with the invention of the Shaker Dust Collector by Wilhelm Beth in Germany. Wilhelm introduced a baghouse unit connected to machines via ductwork to collect sawdust and similar materials. The filter elements in this system are self-cleaned using a vibrating motor attached to the frame, which shakes the filter bags to dislodge accumulated dust.

Over time, the design of the Shaker Dust Collector was refined, incorporating better filters capable of capturing smaller particles while maintaining optimal airflow and efficiency. Although still in use today, Shaker Dust Collectors have declined in popularity due to their relatively low air-to-cloth ratio and large footprint, which demands considerable space.

Cartridge Dust Collector

In the early 1970s, the dust collector saw another evolution with the introduction of the cartridge collector. This innovation replaced the fabric in baghouse filters with cartridge media, offering finer filtration. Capable of efficiently filtering particles as small as 0.3 microns, cartridge collectors excel in removing fumes from the air.

New Dust Collection Options

In the mid-1900’s, environmental regulations became more common and major polluters came under pressure to clean up the massive amounts of dust they generated. Shaker bags and basic fabric filters could not handle the task.

Reverse air baghouses were invented around this time, shortly followed by pulse jet baghouses. These provided tremendous improvements in dust collection by setting up an arrangement of filtration bags that could be cleaned by fans or compressed air pulses instead of shaking. These methods kept the bags cleaner and increased the efficiency of the filters.

The invention of baghouses brought a new era in the history of dust collection. Both types of baghouses are still in use today, and they continue to work well. They are especially useful in applications with high temperatures and high humidity. Bags are now made of a wide variety of materials specialized for different needs.

The Future of Dust Collection

As technology continues to evolve, the future of dust collection holds exciting possibilities. Integration with smart devices and cloud-based platforms could enable remote monitoring and control of dust collection systems, empowering operators to manage their systems with unprecedented efficiency and flexibility.

Troubleshooting Your Dust Collector Pulse Jet Cleaning System

Overview of a pulse jet top load baghouse

For a dust collection system to operate efficiently, the filter cleaning system must be designed, installed and maintained properly. The following troubleshooting basics are intended to help avoid common pitfalls. (Note: Think of these tips as your dust collector’s GPS – they won’t replace the regular check-ups, but when your collector decides to throw a fit and send you through a back road, you will be better prepared to come back on track without losing lots of time or resources…)

When issues arise, it’s essential to troubleshoot effectively. Start by asking, “What has changed?” It could be a worn component or a shift in the operating environment. Even adding a single pickup point can impact the entire system.

Key Steps for Troubleshooting

A correct dP reading is vital for performance tracking.

Check Differential Pressure (dP): Measure with a magnehelic gauge to assess filter media condition. The dP across the filters should slowly increase as dust builds up on the filters, then suddenly decrease when the cleaning system fires a pulse of compressed air, cleaning the filter and reducing pressure across the filter.
Troubleshoot dP Gauge: As part of your periodic inspection process, remove the air lines connected to your dP gauge and ensure there are no obstructions or leaks in the lines. Replace old lines and ensure airtight connections. Even a small amount of dust in the gauge will lead to false readings or foul the gauge.
Listen for Problems: With the cleaning system active, listen to the pulse jets fire. You should hear a tight blast of air. If it sounds “off” – you hear a squeak, a rattle, a click but no air, etc. it is a sign that something requires attention. Most common issues are worn diaphragms (rattle or puff sound), leaks in connecting hoses (hiss sound), and stuck solenoids (a click but no air noise).
Check Compressed Air Pressure: Ensure your system has a compressed air gauge nearby so you can check it as part of your daily or weekly inspection. Review your equipment manual to ensure compressed air is set to the correct pressure. Ensure that your compressed air is clean and dry.
Timer board with lights off indicating no power

Timer Board Settings: Less common issues arise with the timer board, most often due to a surge in electricity or an unauthorized change in the board settings. If you have a ‘clean on demand’ setup, the pulse cleaning system will only fire when the dP reaches a high limit. Equally important is the low limit, where the cleaning shuts off. There are other settings that can be programmed on your control board such as On-Time and Off-Time that control how long the valves are open for and how long it waits between firing the valves. Once set, these should only be changed by authorized personnel. Most timer boards have indicator lights that will flag errors or basic issues. Refer to your equipment manual to ensure all settings are correct.

In the following video, you will see an overview of a system, from the blowpipes and diaphragm, to the control box. Actively listening to how your valves shoot will help you identify the most common issues.

6. Other Common Pulse-Cleaning System Issues: Less common (but still important to know) issues include damaged or out of position blowpipes, stuck solenoids, water or oil in compressed air source, and electrical wiring issues.

When to Troubleshoot

Taped up pulse valve connecting tube indicating likely air leak location

High dP without filter life exhaustion is your first indication of a cleaning system malfunction. If the dP seems off, start by listening for the pulse valves to fire, then run through the items above to identify the issue.

Adjust Timer for Medium-Pressure Systems: Lengthen pulse intervals by adjusting the timer to fill the reservoir adequately. Check for leaks and loose connections before replacing components.

Beyond Cleaning System Issues:

Filter Inspection: Assess filter condition and look for moisture or caking issues.
Environmental Conditions: Consider variations in temperature and humidity, especially in colder regions.
Wear and Corrosion: Monitor aging systems, especially if handling abrasive or corrosive materials.
Human Factors: Be aware of unintended actions like shutting off compressed air or adjusting fan dampers.
Long-Term Monitoring: It is a good practice to monitor the system (specifically the dP) over an extended period to identify patterns or external factors affecting performance.

Hopefully, these tips will be able to guide you through unexpected challenges as a GPS, navigating the potential issues and ensuring your operations stay on track without losing valuable time or resources.
