An air volume regulating device for bag filter (Practical)

Xingtai Delong iron and steel project

The working principle of pulse bag filter is to enter the dust containing gas into the ash hopper from the air inlet or into the filter bag chamber through the open flange port. The dust containing gas enters the gas chamber through the filter bag as clean gas, and then passes through the exhaust port of the clean gas chamber and is discharged by the fan. The dust accumulated on the outer surface of the filter bag and increased continuously, which increased the resistance of the pulse bag filter. In order to make the equipment resistance no more than 1200pa, the pulse bag filter can continue to work, and the dust on the filter bag needs to be removed regularly. The ash cleaning is to start the artery flushing valve in a regular sequence controlled by the program, so that the compressed air in the air bag is ejected from the orifice of the jet pipe, and the surrounding air several times that of the primary air is induced into the filter bag through the venturi pipe, so that the filter bag expands rapidly in an instant, and shake off the dust with the reverse action of the air flow to achieve the purpose of ash cleaning.
