This equipment can absorb the waste gas to the equipment draught through the effects of wind turbine gravity. The equipment draught is installed with flame arrester,
which can hinder the flames, and the dusty gas enters into the lifting room. By adopting gravity and upward air currents, firstly the coarse particles will directly fall to the ash-chute, and the particle dust will be collected by the filter barrel on the outer surface. The cleaned gas will flow to the clean room through the filter barrel center after purification, and then be discharged from the vent through absorption equipment. The gas complies with Grade I emission standard of GB16297-1996 National Emission Standard for Air Pollutants.
