The dusty gas enters the equipment from the inlet of the dust collector and is evenly distributed to each filter bag through the action of the guide plate. The dust in the gas is blocked on its surface by the filter bag, while the purified gas passes through the filter bag and is discharged from the air outlet. Over time, dust accumulates on the surface of the filter bag, and when it reaches a certain thickness, it will affect the filtration effect. At this time, the filter bag is cleaned by the cleaning system, and the dust is shaken off into the ash hopper of the dust collector, and then discharged through the ash discharge device.
