Therefore, my country has restricted the smoke to be discharged into the atmosphere only after dust removal reaches the standard.

Dust collectors are widely used in industrial enterprises. Dust collectors are mainly used to remove dust particles in flue gas. Nowadays, dust collectors come in various forms and have different dust removal methods. At present, dust collectors that are widely used mainly include bag filter, Pulse dust collector, bag filter, cyclone dust collector, electrostatic precipitator and wet dust collector, etc., have less dust content in the flue gas after dust removal, and the flue gas is discharged into the atmosphere without causing air pollution, so it is welcomed by people.

When the dust concentration in the gas is low, the gas enters the buffer zone 3 through the filter holes on the surface of the rubber barrel 12, and the dust with larger particles When the dust concentration in the gas is high, the pressure inside the rubber barrel 12 increases, and the filter holes on the surface of the rubber barrel 12 increase due to the stretching effect.
