(Summary description)Dust bag is a kind of dry dust removal device, which is suitable for collecting fine, dry non fibrous dust. The filter bag is made of textile filter cloth or non-woven felt. The filtering function of fiber fabric is used to filter the dusty gas. When the dusty gas enters the bag filter, the dust with large particles and large proportion will settle down due to the action of gravity and fall into the ash hopper. When the gas with small dust passes through the filter material, the dust will be retained and the gas will be purified.

Dust bag is a kind of dry dust removal device, which is suitable for collecting fine, dry non fibrous dust. The filter bag is made of textile filter cloth or non-woven felt. The filtering function of fiber fabric is used to filter the dusty gas. When the dusty gas enters the bag filter, the dust with large particles and large proportion will settle down due to the action of gravity and fall into the ash hopper. When the gas with small dust passes through the filter material, the dust will be retained and the gas will be purified.
Generally speaking, the efficiency of dust removal bag is not high enough. Filter materials used for a period of time, due to the influence of screen filter, collision, retention, diffusion and static electricity, a layer of dust accumulates on the surface area of the filter bag, which is called the first layer. After the movement process, the main layer has become the main filter layer of the filter materials. Relying on the role of the main layer, the filter materials with larger mesh can also obtain higher filtration efficiency. With the accumulation of dust on the surface of the filter, the efficiency and resistance of the dust collector are improved correspondingly. When the pressure difference between the two sides of the filter material is very large, some fine dust particles attached to the filter material will be squeezed, reducing 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, the resistance of the dust collector should reach a certain value, and it should be cleaned in time. Do not destroy the first layer when cleaning, so as not to reduce the cleaning efficiency. The structure of bag filter is mainly composed of upper box, middle box, lower box (ash hopper), ash removal system and ash removal mechanism. The performance of bag filter is good or bad, in addition to the correct selection of bag filter materials, the dust removal system plays a decisive role in the bag filter. Therefore, the dust removal method is one of the characteristics of the bag filter, and it is also an important link in the operation of the bag filter.
