Large industrial filter drum dust collector  after the dust-bearing gas enters the dust collector under the guidance

of the fan, due to the sudden expansion of the air flow end face and the action of the air flow distribution plate,

some of the coarse dust particles in the air flow settle to the ash hopper under the action of gravity and inertia force.

Large industrial filter drum dust collector the dust particles with fine particle size and small density enter the filter

chamber, and through the combined effect of Brown diffusion and fiber interception, the dust is deposited on the

surface of the filter material of the filter cylinder, and the purified gas enters the clean air chamber and is discharged

by the outlet through the fan.

The resistance of filter dust collector increases with the increase of dust accumulation on the surface of the filter

cylinder. When the resistance reaches the set value, a high-speed high-pressure air is sprayed out through

the small hole of the blowpipe through the pulse valve of the blowback system. At this time, the PLC program

controls the opening and closing of the pulse valve. When the pulse valve is opened, the compressed air in the

air bag enters the filter cylinder evenly through the expansion of the venturi tube, forming a momentary positive

pressure inside the filter cylinder, generating huge vibration, so that the dust deposited on the filter material

falls off and falls into the ash hopper. The collected dust is discharged into the ash bucket through the ash

discharge valve.
