Dedusting Dust Collector In Cement Plant / Industrial Baghouse Dust Collector

While the air dust filter working, the dusting gas gets into the ash hopper from the inlet. With the sudden drop in wind moving speed, the big dust particles fall into the hopper directly, and the gas with small dust particles penetrates the filter bag under the negative pressure of the fan, at this time the dust is prevented on the outer surface of the filter bag. The purified air is exhausted into the atmosphere by the fan. The above process is called dedusting.

With the dedusting continuously running, the dust which attached to the outer surface of the filter bag is increasing more and more. When some filter unit’s running resistance increases and needs to do ash cleaning, this filter unit’s switch valve will close and stop working. The compressed air enters into this filter unit in reverse through electromagnetic pulse valve and blows off dust on the outer surface of the filter bag. Then the switch valve plate will open and the filter unit reworks, the ash cleaning will turn to the next filter unit. The whole ash cleaning process is conducted by the alternation of each filter unit.
