step four: the pulse valve (32) is opened, compressed air in the air storage tank (11) passes through each air injection pipe (12) and is downwards sprayed out through the air injection nozzle (13), the filter bag (8) is rapidly expanded, dust attached to the surface of the filter bag (8) is separated and falls into the dust collection hopper (3) below, and the dust is discharged through the dust discharge port (33) at the bottom of the dust collection hopper (3).
