Introduction To Impulse Dust Filter

Aug. 01, 2018

The Impulse Dust Filter provide by Flour Mill Manufacturer is a new high-efficiency pulse dust collector improved on the basis of bag filter. It combines the advantages of sub-chamber back-blowing various pulse jet dust collectors, and overcomes the shortcomings of insufficient chamber dust-removing strength and uneven distribution of inlet and outlet winds. Expanded the scope of application. The pulse dust collector is when the dust-containing gas enters the dust collector from the air inlet, first hits the sloping plate and the baffle in the middle of the air inlet and outlet, the air flow is turned into the ash hopper, and the air flow speed is slowed down, and the coarse particles in the gas are caused by the inertia. The dust flows directly into the ash bucket. As a function of pre-dusting, the airflow entering the ash bucket is then folded upwards and collected through the filter bag dust containing the metal skeleton inside, and is collected on the outer surface of the filter bag, and the purified gas enters the upper cleaning chamber of the filter bag chamber, and is collected. When the tuyere is discharged and the dust-containing gas is purified through the filter bag, the dust accumulated on the filter bag increases with time, and the filter bag resistance is increased, so that the treatment air volume is gradually reduced, and the normal operation is to be controlled. The resistance is within a certain range (140--170 mm water column). Once the range is exceeded, the filter bag must be cleaned. When the dust is cleaned, each control valve is triggered by the pulse controller to open the pulse valve. The compressed air in the air bag is blown by the blow pipe. Each hole is sprayed into each corresponding filter bag through the venturi tube, and the filter bag is suddenly expanded rapidly, so that the dust accumulated on the surface of the filter bag is detached, and the filter bag is restored to the initial state. The dust falls into the ash bucket and is discharged through the ash discharge system. Thereby, the dust accumulated on the filter bag is periodically pulsed and cleaned, so that the purge gas passes normally, and the dust removal system is operated.
