GMC type high temperature flue gas pulse bag dust catcher by ash hopper, enclosure, filter bag, automatic clear ash blowing device and other parts. Work, by the high temperature flue gas inlet into the dust catcher, first met through the inclined plate, the middle of the air duct airflow was turning down into the hopper, due to the gravity sedimentation, coarse dust particles directly into the bottom ash hopper, have the effect of dust in advance, at the same time air velocity slowing, slight dust currents turn upward into the box, dust by dust bag filter resistance, attached to the external surface of the filter bag, filter the clean gas through the filter bag into the box body upper net gas chamber to the outlet, the induced draft fan to the atmosphere.
    Product are attached to the outside of the filter bag dust increases, when the set time or set differential pressure, pulse interval control instrument order trigger pulse electromagnetic valve open, make the compressed air compressed air bags for each row of filter bag by spray torch pulse blowing ash removal, the filter bag swelling in an instant shake product attached to the outside of the filter bag dust, stripping from the filter bag dust settling to the hopper, after the discharge valve discharge.
