In an earlier blog, titled Cartridge Dust Collectors Explained, we discussed cartridge dust collectors and highlighted the applications for this type of industrial dust collector. Now, let’s take a look at baghouse dust collectors and what applications this system is most optimal for.
Baghouse dust collectors use long, cylindrical bags (or tubes) made of fabric to filter dust particles out of the airstream. The dirty air enters the dust collector and is directed to the filters of the baghouse. Dirty air passes through the bags where the dust particulate is collected outside the filter while clean air passes through the filter. The clean air is released into the environment or recirculated back into the facility.
Most baghouses have a filter clean system of one type or another. There are three common types of filter cleaning systems.
In all cases, once the dust is off the bag, it should end up in the hopper, where it will ultimately be deposited into a container of choice.
Choosing between a baghouse system and a cartridge system is primarily application-based, though it can be a case-by-case situation. There are many factors that play into this.
High Temperature
Baghouse dust collectors can withstand higher temperatures than cartridge dust collectors. If your application requires temperatures above 250 degrees Fahrenheit, it’s often best to opt for a baghouse system.
Sticky Materials
Sticky or adhesive particulates are better collected in a baghouse dust collection system. A bag filter is better suited for the release of the sticky particulate than a cartridge filter. Therefore, a baghouse dust collector is better for adhesive applications than a cartridge dust collection system.
Heavy Dust Load
The more dust you’re collecting, the more likely you are to need a baghouse dust collector. Although not as efficient as a cartridge, baghouse dust collection systems are great for particulates in the five micron-plus range and are great with heavy dust loads.
Durability
Some of the most challenging and heavy loading applications benefit from the use of baghouse dust collectors. The bag filters are durable, flexible and typically have a longer service life than cartridges, reducing the frequency of filter replacements.
This type of filter consists of cylindrical bags (or tubes) made of fabric. Bag filters are typically used for heavier loading applications.
The filters are key to the performance of a dust collection system. Using the wrong filter type can result in an inefficient dust collector. Using the right filter matters, and the first step in determining which type of filter you should be using comes down to the application you’re using it for.
A.C.T. Dust Collectors has manufactured and installed hundreds of dust collectors both indoors and outdoors, including these two 10,000 CFM baghouse dust collection systems, which helped a grain milling facility with its dust collection needs.
