Pulse Cloth Bag Filter Bunker Top Baghouse Dust Collection System CE Passed

Bag filter is a dry filter. It is suitable for trapping fine, dry and non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt. The filter function of the fiber fabric is used to filter the dust-containing gas. When the dust-containing gas enters the bag filter, the dust with large particles and large proportion falls into the dust hopper due to gravity. When the gas containing smaller dust passes through the filter material, the dust is blocked and the gas is purified.

Bag filter is a dry filter. After using the filter material for a period of time, due to the effects of screening, 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. In the later movement process, the primary layer becomes the main filter layer of the filter material. Relying on the role of the primary layer, the filter material with larger mesh hole can also obtain higher filtering efficiency. With the accumulation of dust on the surface of the filter material, the efficiency and resistance of the dust collector increase 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 through, which will reduce the efficiency of the dust collector. In addition, the excessive resistance of the dust collector will significantly reduce the air volume of the dust removal system. Therefore, when the resistance of the dust collector reaches a certain value, it is necessary to clear the dust in time. The primary layer should not be destroyed during ash cleaning in order to avoid the decrease of efficiency.
