The dust gas enters into the filter chamber by the ash bucket (or the lower open flange), and the rough particles directly drops in the ash bucket or ash bin. Filtered through the Filter-bag, the dust is kept in the bag table while the net gas is passed through the bag to the air cleaning chamber, in which the air is discharged into the atmosphere by the fan.
When the dust on the surface of the filter is increasing, leading to the equipment resistance rises to the set value, the time relay (or the micro differential pressure controller) will release the signal. Meanwhile, the program control instrument began to work, and the pulse valve is opened one by one, so that the compressed air is injected through the nozzle to clean the Filter-bag. During this process, the Filter-bag is abruptly inflated, the dust in the bag surface quickly detaches from the Filter-bag and falls into the dust (or ash bin) under the action of the reverse airflow, then the dust is discharged by the flap valve. In addition, The line by line process of injection is only for the filter-bags cleaning, and other Filter-bags are still filtered normally.
