I. working principle

The long bag low pressure pulse dust collector is mainly composed of upper box body, middle box body, ash hopper, ash discharge device, spray device and control device. Dust is blocked to stay on the outside of the filter bag. Clean smoke enters the bag and is discharged by the outlet through the mouth of the bag and the upper box. When growing on the surface of the filter bag dust, lead to equipment resistance rises to the set value (or to set a time), when the micro differential pressure controller output signal, electric apparatus and signal, make the blowing system work, first lift valve closed the first room, then the compressed air from the first chamber air bag order after the pulse valve and spray nozzle on the torch to the filter bag injection, acceleration and reverse airflow generated in a filter bag expansion, under the action of bag for dust from filter bag into the hopper, dust discharge by the discharge valve, injection time duration was 0.065 ~ 0.12 seconds, after the injection, the second pulse injection valve, After spraying all the pulse valves in turn, open the lifting valve in the first chamber, the filter bag in the first chamber immediately returns to the filtration state, and then the next chamber begins to repeat the above cleaning work, and the cleaning work of all Chambers is completed in turn. Dust in the dust hopper of the dust collector is regularly discharged by the ash conveying system.
