Preferably, the bottom of the bag-type dust collector body is provided with a spiral feeder, and the inclined feed opening is communicated with a feed opening of the spiral feeder.

By adopting the technical scheme, the dust is discharged into the spiral feeder from the inclined feed opening, and then is conveyed back into the incinerator for incineration through the spiral feeder.

Preferably, the side wall of the bag-type dust collector body is provided with an access door, and the access door is connected through a lock catch.

By adopting the technical scheme, the bag-type dust collector can be overhauled and maintained in the bag-type dust collector body through the access door, and the access door is convenient for workers to open and close through the lock catch.

Preferably, a filter screen is arranged in the exhaust port.

Adopt above-mentioned technical scheme, the dust in the further filtration gas further promotes dust removal effect.
