Environmental protection equipment bag filter – Longfa

After the filter material is used for a period of time, a layer of dust accumulates on the surface of the filter bag due to effects such as screening, collision, retention, bag filter diffusion, and static electricity. This layer of dust is called the first layer. During the subsequent movement, The first layer becomes the main filter layer of the filter material. Depending on the effect of the first layer, the filter material with larger mesh can also obtain higher filtration efficiency. With the accumulation of dust on the surface of the filter material, the efficiency and resistance of the dust collector will increase accordingly. When the pressure difference on both sides of the filter material is very large, some fine dust particles that have attached to the filter material will be squeezed away. Decrease the efficiency of the dust collector. Besides, the high resistance power will dramatically lower air volume of the dust collecting system. Therefore, after the filter resistance reaching a certain volume, the dust should be cleaned in time.
