How to Enhance Your Dust Collection System | Aerodyne

Posted by Tom Hobson on Nov 29, 2023 3:15:00 PM

Maintaining a clean and safe working environment is essential, especially in workshops and industrial settings where dust and airborne particles are common byproducts. A well-designed dust collection system is crucial for both the health of workers and the longevity of machinery. We will explore various ways to enhance the performance of your dust collection system, ensuring optimal efficiency and effectiveness.

1. Assess Your Current System

Begin by evaluating your existing dust collection system. Identify any bottlenecks, leaks, or areas where the system might be underperforming. Consider factors such as ductwork layout, filter condition, and the capacity of the collection unit. This initial assessment will provide valuable insights into the specific areas that need improvement.

2. Proper Ductwork Design

Efficient ductwork design is fundamental to the success of any dust collection system. Ensure that the ducts are appropriately sized to maintain a consistent airflow velocity. Minimize bends and turns in the ductwork, as these can lead to pressure drops. Straight and smooth ducts allow for better particle transport, reducing the likelihood of dust settling and clogging the system.

3. Optimize Airflow and Velocity

Achieving the right balance of airflow and velocity is critical for an effective dust collection system. Too much or too little airflow can compromise performance. Consult equipment manuals or an HVAC professional to determine the optimal airflow rate for your machinery and workspace. Adjust the system accordingly to maintain a consistent and efficient collection of dust particles.

4. Regular Maintenance

Frequent maintenance is key to the longevity and efficiency of your dust collection system. Check and replace filters as needed, inspect ductwork for leaks, and clean out any accumulated dust or debris. Neglecting regular maintenance can lead to reduced system performance and potential safety hazards. Develop a maintenance schedule and adhere to it diligently.

5. Invest in High-Quality Filters

The effectiveness of a dust collection system heavily relies on the quality of its filters. Consider upgrading to high-efficiency filters that can capture smaller particles, providing a cleaner and healthier workspace. HEPA (High-Efficiency Particulate Air) filters are an excellent choice for trapping even the tiniest airborne particles, contributing to improved air quality.

6. Utilize Secondary Filtration

In some cases, incorporating secondary filtration can enhance the overall performance of your dust collection system. Cyclone separators and baghouses are examples of secondary filtration devices that can capture larger particles before they reach the main filter. This not only extends the life of the primary filter but also prevents premature clogging.

7. Consider Variable Frequency Drives (VFDs)

Variable Frequency Drives (VFDs) enable you to adjust the speed of your dust collection system's fan motor. By varying the speed based on demand, you can optimize energy consumption and maintain consistent airflow. This not only contributes to cost savings but also ensures that the system is operating at peak efficiency.

A well-designed and properly maintained dust collection system is a valuable asset for any workspace. By assessing your current system, optimizing ductwork design, maintaining regular upkeep, and investing in high-quality filters, you can significantly improve the efficiency and effectiveness of your dust collection system. Implementing these improvements not only contributes to a healthier working environment but also enhances the longevity and performance of your machinery.

Extending Filter Lifespan with Cyclone Pre-Filters | Aerodyne

Posted by Tom Hobson on Oct 31, 2023 1:30:00 PM

Baghouses and Cartridge collectors are very good at removing dust from their air. However, when the dust concentration is high, or the dust is abrasive, wet, sticky or fibrous, the baghouse filters can have issues.  

  • High concentration will plug of filters quickly.
  • Abrasive dust will cause holes to develop in the filters.
  • Wet and sticky dust will plug up the filter and/or cause filter failure.
  • Fibrous dust will not easily fall to the hopper causing filters to plug.

Installation of a cyclone pre-filter is an ideal way of extending filter life.  The cyclone uses centrifugal forces to capture the dust and remove it from the airstream.  Often times the cyclone will remove 80-90% of the dust before a baghouse or cartridge collector.  This allows the filters to concentrate on the smaller dust that makes it past the cyclone.

And if you have a pulse-on-demand controller for your baghouse, you will further extend the filter life, as the filters will only be cleaned when required.

What is a cyclone dust collector?

Cyclone dust collectors are dust collectors that use centrifugal motion to remove dust from an airstream. They don’t have any moving parts and don’t use filters for dust removal. Most cyclones are vertical in design, even though Aerodyne Environmental has compact horizontal cyclone designs. They are often used as pre-filters to increase baghouse, cartridge collector and wet scrubber system efficiencies.

What is a cyclone pre-filter?

Cyclone pre-filters are cyclones installed before a baghouse or cartridge collector to increase the removal efficiency of the system.  They extend filter life and lower utility usages. The cyclone pre-filter is often used on those applications that have “Tough” dust.  “Tough” dust would be dust that is abrasive, hygroscopic, fibrous and/or wet. Often times this dust will cause operational issues with baghouse and cartridge collectors.

Why install a cyclone pre-filter?

Cyclone pre-filters are installed to optimize a dust collection system. This could mean increasing the removal efficiency of an existing dust collection system. It could be to extend filter life by decreasing the dust loading the filters are seeing, thereby decreasing the cleaning required. 

Additionally, cyclone pre-filters will lower compressed air/plant air usage by increasing the intervals between cleaning when a pulse-on-demand control system is used with it. And in those special applications, the Aerodyne SplitStream cyclone can add hot or cold air into the dirty airstream, thereby treating the air while collecting dust.

Signs You Need a Pre-Filter

The following are some signs that your dust collector isn’t operating up to par and you should look at installing a cyclone pre-filters.

  1. There is a high pressure drop across your filters. This is caused by the dust building up on the filters and not being cleaned off fast enough.  The high pressure drop causes the fan to pull less air to compensate, thereby letting more dust out on to the shop floor.
  2. Filters are being replaces too fast! The most common filter failures are by developing holes or plugging up.  Both failures are tied to high dust loadings.
  3. Valuable product or raw material is being disposed in the dust collector waste due to contamination. As stated above, filters build up dust layers to provide the removal efficiency. Those filters will retain the material over time. If the material is valuable, this can be a lot of money that is going to waste. Pre-filters will allow the material to be collected and used in the process or product before it can be contaminated in the filters.
  4. Do you have a high cost of water treatment and disposal of the scrubber blowdown? When wet scrubbers capture particulate, slurry is formed. This slurry will then have to be disposed. It will often be sent to a water treatment plant. The water treatment plant might be dedicated to the facility or municipal. Either way, additional costs are added to treat the slurry before it is disposed of or reused. A pre-filter removes a portion of the material before it is put into slurry, thereby saving costs on waste-water treatment.
  5. Similar to above, since wet scrubbers form slurries, any valuable material collected in the wet scrubber will be in that slurry. So, unless the desired state of the material is within the slurry, it will have to be processed to make it useful. This means additional steps (and expense) are required to recycle the material. A cyclone pre-filter removes the material dry, before it is in slurry, thereby saving costs.

So, before you decide to purchase a new dust collector, look into the benefits of installing a cyclone pre-filter.  You just might save yourself money!

What Is A Dust Collector? | Aerodyne

Posted by Tom Hobson on Mar 30, 2023 1:15:00 PM

A dust collector is a mechanical device used to remove dust from an air stream. The dust collection system consists of a hood (or air collection device), the dust collector, the motive fan and any inter-connecting ductwork, stack, dampers, controls, etc. Aerodyne Environmental manufactures cyclone dust collectors and the dust handling valves (airlocks) mounted on the dust collectors. 

To properly specify a dust collector, certain information is required:

  1. Dust collector typeCyclone, baghouse, etc.
  2. Airflow (CFM) – The amount of air going through the collector. The airflow is critical to sizing a dust collector and without airflow no collector can be sized.
  3. Temperature, pressure, humidity of airflow – Higher temperature, pressure, and humidity will affect collector materials of construction, size and may require special valves and controls.
  4. Dust description* – The better you describe your dust the better your dust collector will operate. Example a sticky dust will bind a cartridge collector which will require frequent cleaning and/or replacing of the cartridges. While cyclones are well suited for sticky particulate.

    a. SG or density of the dust/particulate – the greater the density, the easier it is to remove.

    b. Dust/particulate loading (lbs/hr) – amount of dust.

    c. Particulate size distribution (microns) – how big is the dust (smaller dust is removed in baghouse but larger dusts can be effectively removed in a cyclone).

    d. Fibrous, abrasive, hydroscopic, granular, tendency to bridge, sticky, etc. (dust with these properties can wreck havoc on baghouses and cartridge collectors.
  5. Removal efficiency required – The greater the removal efficiency, the more expensive the design will be.
  6. Materials of construction required – from carbon steel to stainless and high alloy steel, the materials of construction affects price. Process conditions (temperature, gas/air composition, dust composition and humidity) can require specific materials of construction. (Example: salt in a humid environment requires stainless steel to prevent corrosion.)

    *If unknown, a pilot unit can often be rented from the manufacturer to test on your existing system.

Dust Collection Systems Maintenance: The Cyclones and Filter Collectors | Aerodyne

Posted by Tom Hobson on Feb 28, 2023 2:15:00 PM

Dust collection systems pick up dust generated by process equipment and move it away for disposal or to be recycled. They use hoods to gather the air around the dust generation equipment. The dusty air is then sent to the dust collection equipment through ductwork. The dust collection equipment often consists of a pre-filter to help collect the dust followed by the main dust collector. An exhaust fan is often at the end and it powers the system by pulling the air through each of these components.

Cyclones

Cyclone dust collectors are very dependent on the airflow that is going through them. Cyclone pressure drops are based on many factors, but the two most important are the geometry of the cyclone and the volumetric airflow through the cyclone. The pressure drop formula of a cyclone has the square of the volumetric airflow through the cyclone. So, doubling the airflow will quadruple the pressure drop (2x ACFM leads to 4x dp). If your airflow changes through the system, the pressure drop through your cyclone can fluctuate. 

Since dust collection system static requirements are all related, the exhaust fan will find its operating condition naturally. However, if the airflow decreases, then the removal efficiency of cyclone will decrease too. This means the cyclone will remove less of the finer dust particles, thereby sending them on to the filters. That will cause greater dust loading for the filters, which could increase the frequency of cleaning (more plant air usage, greater filter wear, etc.) and decrease the lifespan of the filters.

Filter Collectors

Filter collectors would actually benefit from lower airflow. The lower airflow would decrease the air to cloth ratio, which can extend the life of the filters. However, as described in the rest of this paper, the overall performance of the dust collector system will decrease. And if the system has a cyclone dust collector, the benefits gained by a lower a/c ratio could be counteracted by higher dust loading coming through the cyclone.

Higher airflow will increase the air to cloth ratio and could put more strain on the filters. The velocity of the air going through the filter could increase enough that holes in the filters could develop, thereby causing dust to bypass the filters.

However, filter collectors have a pretty good range of airflows they can handle without significant effect on the system. Unlike cyclones, the pressure drop in a filter is based less on airflow and more on the filter pack on them.

5 Ways to Go Green in Dust Collection | Aerodyne

Posted by Tom Hobson on Sep 29, 2022 3:00:00 PM


  1. Use pulse-on-demand controller for baghouse and cartridge collectors

    Pulse-on-demand controllers allow you to clean your filter less often. Less pulses helps you save compressed air and reduces wear and tear on the filters. Cutting down on compressed air means less electricity is required in the compressors and less wear and tear on the filter means they last longer.
  2. Install a cyclone pre-filter

    A cyclone pre-filter will help remove dust before it gets to your filters. This means that the dust loading on the filters will decrease, which helps extend their life by requiring less cleaning and plugging them up less. The cyclone can also allow you to recycle the material without contamination and possibly increase the total removal efficiency of the system.
  3. Monitor airflow in the dust collection system

    Dust collection systems are designed to capture dust and they should be operating at design specifications. By monitoring the airflow, you are confirming that the unit is operating correctly. If the airflow is off from its design condition, then you will not be capturing the material that it was designed to capture. Measuring the airflow is similar to measuring the temperature in an oven. Without measuring it, you won’t know if you are at the correct performance and the end result may be off.
  4. Install Aerodyne Vacu-Valve (if appropriate)

How Important are Dampers in a Dust Collection System?

Posted by Tom Hobson on Jun 28, 2017 1:19:22 PM

Dampers are used in dust collection systems to control the airflow to specific branches of the ductwork.  This is done by opening or closing the damper.  Air, like water, travels the path of least resistance.  By using a damper, you are changing the resistance to the air.  Every dust collection system should have a manual damper near each hood/pickup point to balance the system.  This makes sure that the system is properly operating.  An unbalanced system could cause too much air to be pulled from one area (causing loss of product) while in another area not enough airflow is available to capture dust.  Other times, a soft connect (space between flanges) is used to control airflow at a pickup point.  However, this isn’t very efficient.  This keeps the airflow in that area constant, but it’s picking up air from an area where it isn’t required.  A damper would work much better, since you are only moving the air in the area you need.  Soft connects are only advantageous when you are looking to cool down an airflow using outside air.  Dampers can also be used to shut off portions of the system that are not being used, thereby allowing a smaller system.

 

So when you are looking at your dust collector system, don’t forget dampers.  They allow you to optimize your system.

Which 4 major items can cause a dust collection system to underperform?

Posted by Tom Hobson on Jun 15, 2017 9:15:00 AM

Dust collection systems consist of four major items.  All of them are important and can cause a dust collection system to underperform.  The major items are the exhaust fan, dust collector, ductwork, and hoods/pickup points.   While the exhaust fan provides the motive power to collect the dusty air, its performance is affected by each of the components.  This means that if one of the other components isn’t operating as designed, the whole system will be affected.  Ductwork is usually by far the largest component and often the most overlooked.  Depending on the size of your system, the ductwork can span hundreds of feet and have dozens of side streams.  The ductwork is like railroad tracks, it moves the dusty air from one place to another.

Often times, additional lines will be added to a dust collector system after installation.  Without proper evaluation of the system, this could negatively affect the performance of the whole system.  This means that just because the dust collector system was operating correctly before, it might not after an additional pickup point or hood is added.  What happens is that when you add additional pickup points, you change the balancing of the system.  This could change the airflow to each and every hood and pickup point in the system, so while the system was originally adequately venting an area, it might not after a change.

A few things can be done to address this, such as changing fan speed, adding dampers, modifying ductwork, etc.  The main thing you need to keep in mind is that if you slow the airflow through ductwork too much, you begin to build up dust within the line.  This will further restrict your airflow and become a fire / explosion hazard.

So when you are looking at changing your dust collector system, review the system parameters or hire someone to review so that you do not cause additional issues.

Dust Collection Systems: Product Recovery and Cyclone Pre-filters

Posted by Tom Hobson on May 25, 2017 1:50:57 PM

If you are working with a high value material or product, then you should investigate using a cyclone ahead of your baghouse or cartridge collector.  The cyclone will allow you to recover the dust without contamination from the filters.  The filters in a baghouse or cartridge collector use a dust layer built up on the filters to collect the dust from the airstream.  During the process of filter cleaning, dust from this layer is dislodged and falls into the hopper.  Any particulate from prior batches can cause contamination of the dust.

Learn More About Using a Cyclone as a   Pre-Filter for Your Baghouse

A cyclone, on the other hand, collects the dust and deposits it in the hopper continuously.  There is very little dust buildup inside of a cyclone.  This minimizes the chances of contamination from prior batches.  Since there aren’t any filters, a cyclone can be washed or wiped out to remove the prior batch particles.

One area where this could be very helpful is pigment collection.  A baghouse or cartridge collector filter will collect the pigment and contaminate the color.  This requires the filters to be changed every time a new color is produced.  So the system will require a filter set for every different color produced.  Conversely, the cyclone can be washed out or wiped down between colors.  This saves in both maintenance time and spare parts costs.
