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

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

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.

Conceptos básicos sobre la colección de polvo

Evolución de los colectores de polvo a través del tiempo

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. Continued research and development efforts may unveil new methods and technologies to further improve dust collection performance, ultimately fostering safer and healthier work environments across various industries.

With ongoing technological advancements, the future holds the promise of even greater strides in optimizing dust collection systems for enhanced workplace safety and environmental stewardship. En Baghouse.com we are always researching and implementing the latest cut edge technologies, continuing to make history in dust collection.

Solución de problemas

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.

Damaged by rust or out of position blowpipes could affect the operation of a pulse-cleaning system

Blowpipes knocked out of position

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.

Caso de Estudio: actualización del sistema de recolección de polvo para guitarras Gibson

Antecedentes

Gibson Guitars, a renowned name in the music industry, faced a critical need to upgrade the dust collection systems in their Bozeman, Montana, and Nashville, Tennessee manufacturing plants. The existing systems were outdated, with operational inefficiencies and lacked compliance with combustible dust safety regulations outlined by NFPA.

Scope of Work - Nashville, TN Plant

Having recently come under new management, Gibson Guitars embarked on a multiyear project to upgrade its dust collection systems at both its Nashville, Tennessee and Bozeman, Montana plants. The goal was to increase efficiency, reduce downtime, and improve the safety and environmental aspects of their systems.

First, Baghouse.com was contacted and asked to conduct a thorough audit of the existing dust collection systems at the Gibson USA plant in Nashville TN, in particular an outdated plenum pulse envelope baghouse that was in desperate need of replacement. The unit had suffered from years of neglect and was in poor physical condition, with large holes on the roof and sides of the unit. Additionally, the system had only partial protection against combustible dust hazards, which the plant wanted to address.

Taking into account their unique needs, we designed a complete dust collection system to meet the current production needs as well as providing for future growth. This included the installation of a new pulse jet style baghouse, a larger system fan, upgraded ductwork, and the integration of NFPA-required combustible dust safety equipment. To ensure compliance with NFPA regulations, explosion vents and an explosion isolation valve were strategically installed. Additionally, explosion-rated equipment, such as rotary valves, replaced non-compliant elements in the discharge system.

Scope of Work at Bozeman, MT plant

The situation at the Bozeman, Montana plant was somewhat different. This plant, which produces all of Gibson’s acoustic guitars, had an existing system that worked well, but that was far too small to account for increased production projections. The expansion of the facility was to take place in two stages: First, a new building was to be built while the existing building and production machines were to keep running. Once the new building was up, the layout of production machines would be completely reworked between the two buildings. Additionally, Gibson asked that the new system be designed and installed in such a way so as to not disrupt existing production and that the changeover be done with little to no downtime. The new system would also need to be able to transition into its expanded role once the facility expansion project was completed in several years.

With these challenging requirements, Baghouse.com set about engineering, supplying, and installing a new dust collection system that: (1) would provide for the current production needs, (2) be capable of nearly 3x capacity when the plant expansion was completed, (3) could be installed without disrupting production, and (4) meet or exceed existing best practice for combustible dust applications.

The solution proved to be a much larger multiple compartment pulse jet baghouse capable of handling 75,000 CFM+. The module (i.e. multiple compartment) style was used to provide additional redundancy and minimize downtime when conducting maintenance. Additionally, the system was outfitted with several protection devices to resolve combustible dust hazards such as high speed abort gates, spark detection, NFPA compliant rotary airlocks and explosion venting.

Importantly, during the design stage we proposed locating the new collector and fan adjacent to the existing baghouse so that it could be installed and brought online without decommissioning the existing system. When the switchover was to take place, we were able to simply extend the existing main trunk of the ductwork over to the new collector and connect the new return air ducting into the building through an enlarged wall penetration.

Eventually, once the new plant layout has been completed, a new, larger interior ductwork system will be installed and reconnected to utilize the full capacity of the new baghouse.

Thew system provides sufficient performance for the existing plant layout and stands ready to handle the estimated 3x increase in demand that will be needed once the plant’s expansion project is completed.

Conclusión

The upgraded dust collection systems led to improved operational efficiency, reducing downtime caused by maintenance issues and gained long-term reliability, reducing the need for frequent repairs and replacements.

Baghouse.com‘s expertise in dust collection systems proved instrumental in providing Gibson Guitars with a reliable, compliant, and efficient solution. These projects not only addressed immediate challenges but also positioned these woodworking facilities to handle the demand placed on them by Gibson’s sustained growth. Additionally, Baghouse.com’s ability to offer complete turnkey solutions allowed for the development of a comprehensive plan covering the collector, system fan, ductwork, combustible dust safety and installation processes so as to minimize production downtime during the changeovers.

We feel privileged to have been able to work with such a great company and to be part of their legacy as they continue to evolve to meet the needs of the 21st century musician.
