Short Description:

The pulse bag filter is composed of ash hopper, upper box, middle box, lower box and other parts, and the upper, middle and lower boxes are divided into chamber structures. When working, the dust-containing gas enters the ash hopper from the inlet duct, the coarse dust particles fall directly into the bottom of the ash hopper, the fine dust particles enter the middle and lower boxes upward with the air flow, the dust accumulates on the outer surface of the filter bag, and the filtered gas enters the upper box to the clean gas collection pipe-exhaust duct, and is discharged to the atmosphere through the exhaust fan. The ash cleaning process is to first cut off the clean air outlet air duct of the chamber, so that the cloth bag of the chamber is in a state where no air flow passes through (the air is stopped in the chamber and cleaned). Then open the pulse valve with compressed air for pulse spray cleaning, the shut-off valve closing time is enough to ensure that the dust peeled off from the filter bag after spraying settles to the ash hopper, avoiding the phenomenon that the dust is attached to the adjacent filter bag surface with the air flow after leaving the surface of the filter bag, so that the filter bag is cleaned thoroughly, and the exhaust valve, pulse valve and ash discharge valve are fully automatic control by the programmable controller.
