what are Filter Bags
May 14, 2018

Bag filter is a kind of dry filter equipment. It is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-woven felt. The filtering effect of the fiber fabric is used to filter the dust-containing gas. When the dust-laden gas enters the bag filter, the particles are larger than the severe dust because of gravity. The action settles down and falls into the ash bucket. When the gas containing fine dust passes through the filter, the dust is trapped and the gas is purified. Generally, the dust removal power of new filter materials is not high enough. After the filter material is used for a period of time, a layer of dust is accumulated on the surface of the filter bag due to the effects of screening, collision, retention, diffusion, and static electricity. This layer of dust is called the primary layer. During the subsequent movement, the initial layer becomes The main filter layer of the filter, relying on the role of the initial layer, the filter material with larger mesh can also obtain higher filtering power. With the accumulation of dust on the surface of the filter material, the power and resistance of the dust collector are added accordingly. When the pressure difference between the two sides of the filter material is large, some fine dust particles that have adhered to the filter material will be squeezed in the past. Reduce the power of the dust collector. In addition, the high dust resistance of the dust collector will significantly reduce the air volume of the dust removal system. Therefore, after the resistance of the dust collector reaches a certain value, it is necessary to clear the dust promptly. Do not damage the primary layer during cleaning to avoid power loss.
