In the whole bag-type dust collector, the filter bag 21 contains a plurality of dust-removing chambers, each dust-removing chamber corresponds to one electromagnetic scavenging valve 15, a plurality of venturi tubes 22 and a corresponding number of electromagnetic pulse valves 26.

Specifically, after the dust-containing gas enters the dust hopper 3 from the air inlet 8, a part of coarse dust particles and condensed dust particles directly fall down due to the inertia effect, and the effect of pre-collecting dust is achieved. The air flow entering the dust hopper 3 turns and flows upwards into the middle box body and the upper part, and when the dust passes through the filter bag 21 with the metal framework arranged inside, the dust is blocked on the outer surface of the filter bag 21. The purified gas enters the cleaning chamber at the upper part of the filter bag 21 and is collected to the air outlet pipe 9 to be discharged.

When the pressure drops to a set low value, the control system outputs a stop signal, the solenoid pulse valve 26 closes and the solenoid gas exchange valve 15 opens.

When the bag-type dust collector works, dust on the outer surface of the filter bag 21 is gradually increased along with the continuous filtration, and the resistance of the bag-type dust collector is also gradually increased. When the set value is reached, the ash cleaning controller (namely the control system controls the ash cleaning system) sends an ash cleaning command to clean the dust on the outer surface of the filter bag 21 and drop the dust into the ash hopper 3, and then the electromagnetic ventilation valve 15 is opened to enable the chamber to recover the filtration. After a suitable time interval, the dust remover performs the dust removal work again in the next chamber.
