  DDF large bag counter blowing dust points to positive pressure type (also called pressure type) and negative pressure type (also called inhaled), the instruction by the negative pressure is introduced.
  Dust under the effect of negative pressure, the gas by into the duct into the hopper, choke plate are set in the front of the air inlet, a coarse dust by touch attack and gravity fall into ash hopper, fine particles of dust after filter bag filter, adsorption on the inner wall of the filter bag of, after purification of the gas by baghouse, through the device by the exhaust pipe inside the suction fan at the top of the switch valve, then through the vent into the atmosphere.
  Dust filter bag with increasing, e., resistance to rise began clear grey. Equipment mode of ash removal by single chamber blow way, when the reverse blowing through the directional control valve, close the exhaust duct, open the blowpipe, cut off the exhaust of the single room. Because the device into the duct of each room is mutually, and are in a negative state, so due to the effect of negative pressure suction of the adjacent room. Make room air through the blowpipe drawn into filter bag, filter bag, air outside into inside the filter pocket, the ash hopper and the room into the duct and suction chamber discharge, the filter bag is flat. The inside of the filter bag dust is then shake sink sink to drop ash hopper, completed the single room dust, the rest of the room in the soot under the control of the actuator, in the same order of ash removal, in addition to a certain value, the ash removal.
