Introduction：
The bag filter is a dry dust filter device. 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, 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 depends on the effect of the first layer, and the filter material with a 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. When cleaning the dust, please do not damage the first layer in case the efficiency decline.
Advantage：
(1) The dust removal efficiency is high, generally above 99%, the dust concentration of the gas at the outlet of the dust collector is within tens of mg/m3, and it has a high classification efficiency for fine dust with submicron particle size.
(2) The range of air volume is wide, the small one is only a few m3 per minute, and the large one can reach tens of thousands of m3 per minute. It can be used for the dust removal of flue gas in industrial furnaces and kilns to reduce the emission of air pollutants.
⑶ Simple structure, easy maintenance and operation.
⑷On the premise of ensuring the same high dust removal efficiency, the cost is lower than that of the electrostatic precipitator.
(5) When using glass fiber, P84 and other high temperature resistant filter materials, it can operate under high temperature conditions above 200 °C.
⑹ Not sensitive to the characteristics of dust, not affected by dust and resistance.
