How to Clean Various Dust Collectors | Aerodyne

When you have a dust collector capturing valuable material, you often have to regularly clean the dust collector to remove the material and if it is perishable, remove it before it contaminates the other material. Some dust collectors are easier to clean than others.

Wet Scrubbers

Wet Scrubbers are pretty much self-cleaning. Since they use water to capture the dust, it pretty much washes the walls and internals regularly. The main issue with wet scrubbers are that if you are trying to use the material (whether in the process or as a product) then you will need to remove it from the water stream (unless having it in a water stream is desirable).Aerodyne November 2020 Blog-2


Cyclones are very low maintenance. Since they use centrifugal motion to remove the material, there isn’t much buildup inside the cyclone. So there really aren’t many places to build up. Designing the vessel with access doors will help keep the cleaning easy. Aerodyne’s horizontal cyclone has a unique design that allows you access to the whole cyclone through its back plate.

Fabric Filters

Fabric filters collect the material on the filters (bags/ cartridges). This builds up a layer of material which remains on it for the life of the filter. During cleaning, the material falling off might have recently been captured or material that has been on the filter for an extended period of time. This could contaminate the material being collected.

  1. Baghouses require the bag to be removed in order to be cleaned or replaced. Often times this is a very time consuming process and can often require workers to enter the baghouse. If contamination is a serious concern, baghouses should not be used.
  2. Cartridge collectors are much easier with replacing the cartridges. Often times this can be done in minutes compared to hours of a baghouse. So you can remove the cartridges, clean them and re-install. This will allow you to clean or replace the filters after each batch, thereby minimizing any contamination.

One option is to install a cyclone dust collector as a pre-filter before your baghouse or cartridge collector. The cyclone will capture the majority of the material without contaminating it for use in your process / product. While the smallest fines will then be captured in the baghouse / cartridge collector for disposal or treatment. This allows you to capture as much of your valuable material with minimal cleaning / contamination while also providing the high removal efficiency for the environment.
