Working principle of pulse dust collector:

When the dusty gas enters the dust collector through the air inlet, the airflow turns and flows into the ash hopper. At the same time, the airflow speed slows down, and due to inertia, the coarse particles of dust in the gas directly flow into the ash hopper. Playing a role in pre dust collection, the airflow entering the ash hopper is then deflected upwards and captured on the outer surface of the filter bag through the filter bag with a metal skeleton inside. The purified gas enters the upper clean room of the filter bag chamber and is collected at the air outlet for discharge. During the process of purifying the dusty gas through the filter bag, as time increases, more and more dust accumulates on the filter bag, increasing the resistance of the filter bag and gradually reducing the processing air volume. In order to work normally, the resistance must be controlled within a certain range (140-170 mm water column), and the filter bag must be cleaned. During dust cleaning, the pulse control instrument sequentially triggers each control valve to open the pulse valve. The compressed air in the air bag is sprayed from each hole of the spray pipe through the Venturi tube to the corresponding one. Inside the filter bag, the filter bag instantly expands rapidly, causing the dust accumulated on the surface of the filter bag to fall off, and the filter bag is regenerated. The dust falls into the ash hopper and is discharged from the machine through the ash discharge system. As a result, the dust accumulated on the filter bag is periodically pulse blown to clean the dust, allowing the purified gas to pass through normally and ensuring the operation of the dust removal system.
