What is a Filter Bag or Filter Bag?
The bag filter in dust collector devices has the primary responsibility of collecting dust generated by the process. The filter bag is determined based on the type of dust particles, their volume, and size. Ultimately, depending on the air flow rate entering the bag filter (Bag Filter) device, its surface area—which includes the number of bags in the device—is determined.
Structure of Filter Bag Fabric
The weave structure of filter bag fabrics is generally divided into two main types based on construction:
Woven-type filter bags, which have warp and weft fibers like regular fabrics.
Non-woven-type filter bags, which are felt-like and lack woven fibers.
Filter Bag Material
The material of the filter bag (or its Material) comes in various types. The selection of the fabric material is determined based on the process, type of pollutant, temperature, pressure, humidity, and chemical composition of the pollutant. Some common types of fabrics used in filtration include:
Polyester (POLYESTER)
Polypropylene (POLYPROPYLENE)
Nomex (NOMEX)
Polyimide (POLYIMIDE)
Fiberglass (FIBERGLASS)
Of course, fabric materials cover a very wide range, and only a few common types are mentioned here. In some cases, depending on the type of pollutant, fabrics made from different fibers not included in the above categories may be used.
Filter Bag Dimensions
The size and dimensions of a filter bag are determined based on its effective filtration area. Each filter bag has a specific shape, typically cylindrical for ease of manufacturing and operation. If we consider a filter bag as a cylinder, the lateral surface area of this cylinder represents the filtration area of the bag. Once the filtration area of a single filter bag is known, the required number of bags in a filter device can be calculated by dividing the total required filtration area by the filtration area of one bag.
