The principle bag house filter system

Bag house is a dry dust filter system,that is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt, and the dust-containing gas is filtered by the filtering effect of the fiber fabric. The big heavy dust settles down due to the action of gravity and falls into the ash hopper,and falls into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is blocked and the gas is purified.

Generally, the dust removal efficiency of the new filter material is not high enough. After the filter material is used for a period of time, due to the effects of sieving, collision, retention, diffusion and static electricity, a layer of dust accumulates on the surface of the filter bag. This layer of dust is called the primary layer. The main filter layer of the filter material depends on the role of the primary layer, and the filter material with larger mesh can also obtain higher filtration accuracy

With the accumulation of dust on the surface of the filter material, the filtration accuracy and resistance of the dust collector will increase accordingly. When the pressure difference between the two sides of the filter material is large, some fine dust particles that have been attached to the filter material will be squeezed. Reduce the efficiency of the dust collector.In addition, the high 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, the dust should be cleaned in time. The primary layer should not be damaged when cleaning, so as to avoid a drop in filtration accuracy.
