Principle of dust removal system of bag-type pulse dust collector

     Bag dust collector is a kind of dry dust collector, which is a dust removal equipment that uses a filter bag made of inorganic fiber woven to filter out solid particles in dust-containing gas. For dust above 2μm, the efficiency can reach 99.9%, and the cost is low, the management is simple, and the maintenance is convenient. The equipment is usually composed of box structure, filter unit, ash cleaning system, ash conveying mechanism, control system, etc.

     Dust-containing gas enters the bag filter, and under the effects of diffusion, gravity, collision, etc., dust within the particle size range will adhere to the dust receiving surface of the filter bag, forming a dust cake, and the clean air will pass through the filter bag and be discharged from the body to achieve air The dust is separated to achieve the purpose of purifying the air. As time goes by, the thicker the dust cake is, the higher the resistance of the dust collector will be, resulting in a decrease in the efficiency of the dust collector. Clean the dust for the normal operation of the system. The purpose of dust removal is to remove the dust adhering to the surface of the filter bag, keep the dust layer within the range, and the system operation resistance fluctuates within the range.
