Function

Industrial dust collector is widely applied for dust collection applications in mining industry, chemical industry, pharmaceutical industry, and the production of flour, glass, metallurgy, mine, cement, building materials, etc. Dust Collector is made up of the top chest, middle chest, bottom chest, dust exhauster, and jet cleaning system. There is spray tube and air outlet at the top chest. The middle box consists of perforated plate, venture tube, filter bag, keel, pulse valve and gas cleaning system. The bottom chest is comprised of ash bucket, air inlet, access door, ash exhauster (which is composed of rotary dust valve or spiral conveyor).

It could be made of carbon steel or stainless steel upon request. Dust collector is generally used with a temperature less than 120°C. Customized dust collector for usage at high temperatures (less 230°C) is also available.

Feature

1) The dust removing efficiency is over 99.9% and emission concentration is less than 30mg/Nm3.
2) High density dust air below 1000mg/Nm3 is available.
3) Off-line pulse cleaning method which can clean ash thoroughly and the running resistance is small.
4) It has stable and reliable performance, high degree of automation and low investment.

Working Principle

While dust collector 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.
