The dust-containing gas enters the ash hopper from the air inlet or enters the filter bag room through the open flange port. The dust-containing gas is filtered by the dust collector bag into purified gas and enters the clean air chamber. Then it passes through the exhaust port of the clean air chamber and is blown by the fan. Drain away. Dust accumulates on the outer surface of the filter bag and continues to increase, causing the resistance of the bag dust collector to continue to rise. In order to ensure that the equipment resistance does not exceed the limit and the bag dust collector can continue to work, the dust on the filter bag needs to be removed regularly. Dust cleaning is performed by The C program controller starts the pulse valve in a timing sequence, so that the compressed air (..) in the air bag is ejected from the blow pipe (called primary air) and induces the surrounding air several times the primary air through the venturi tube (called secondary air) When entering the filter bag, the filter bag expands rapidly in an instant, and the dust is shaken off with the reverse force of the air flow to achieve the purpose of dust cleaning.
