Compressed air is sprayed at high speed to the dust filter bag in a very short time, and air several times the amount of air sprayed is induced to form air waves, causing the filter bag to expand and vibrate rapidly from the bag opening to the bottom, and forming a wave-like deformation of the filter bag that “bulges, deflates, and bulges” back and forth in a short time, causing the dust layer to deform and break, and detach from the filter cloth in a mass and fall under the action of gravity.

When cleaning, the cleaning airflow not only expands and deforms the filter bag, but also passes through the bag wall and the dust layer.

The dust-laden gas enters the middle and lower boxes from the air inlet of the dust collector. When the dust-laden gas passes through the filter bag and enters the upper box, the dust and gas are separated due to various effects of the filter bag. The dust is adsorbed on the filter bag, and the gas passes through the filter bag through the venturi tube and enters the upper box, and is discharged from the air outlet.
