 Bag filter is a dry dust removal equipment. It is suitable for trapping small, dry, non-fibrous dust. The use of non-textile filter cloth bag of felt textile made use of the filtering effect of the fabric filter dust and gas, when the dust and gas into the dust, large particles, heavy dust, due to gravity settling down , fall into the hopper, smaller dust containing gas through the filter, the dust is retention, the gas to be purified. Most of the new filter's collection efficiency is not high enough. Filter used for a period of time, due to sieving, collision, retention, diffusion, electrostatic and other effects, filter bag surface layer of accumulated dust, known as the first layer of this layer of dust, in the course of the campaign after that, became the first layer filter the main filter layer, relying on the role of first layer, the larger mesh filter can also obtain a higher filtration efficiency. With the accumulation of dust on the filter surface, the efficiency of bag filter and a corresponding increase in resistance to both, when the pressure difference on both sides of the filter is large, there would have been attached to tiny dust particles on the filter squeeze past , so that the bag filter efficiency. In addition, the bag filter dust removal system, the resistance is too high air volume decreased significantly. Therefore, the bag filter resistance reaches a certain value, timely cleaning. Cleaning can not be destroyed when the first layer, in order to avoid reduced efficiency. 
 Dust removal equipment, the dust is separated from the flue gas equipment, also known as dust. Mechanism of dust removal equipment is very simple, it's dust masks, like the mechanism is through the filter material in the flue gas fly ash particles on the mechanical block to achieve. But in addition, received the first surface of fly ash particles in the filter also formed a stable layer of dense gray layer (commonly known as filter cake or bed), it played a very good filtering effect, particularly cloth bag with the preparation of the dust removal equipment, this layer of filter bed filter played a major role
