Abstract

The utility model discloses a pulse bag type deduster with annular-space ejectors, which comprises an ash bucket, a filter chamber, an air-cleaning chamber, an air inlet and an air outlet, a porous plate on which filter bags are mounted is arranged between the filter chamber and the air-cleaning chamber, and an annular-space pulse ash remover is arranged on the porous plate. The annular pulse airflow generated by the deduster cannot injure the filter bags, and thereby the service lives of the filter bags are effectively prolonged.

Description

A kind of pulse bag type dust collector that has the annular space injector

Technical field

The utility model relates to a kind of pulse bag type dust collector, particularly a kind of pulse bag type dust collector that has the annular space injector.

Background technology

At present, pulse bag type dust collector known to everybody all is as deashing power with compressed air, the sack center of aiming at filter bag by the high velocity air of injection hole on the winding-up pipe or nozzle ejection enters filter bag, filter bag is sharply expanded, rely on impact shock and back draught and deashing, we are referred to as " center winding-up " deashing.And the purge mode of " center winding-up ", because the winding-up pipe is installed and is difficult to reach influence of various factors such as required precision and thermal expansion, cause the injection hole misalignment, make the air pulse skew of ejection spray to the filter bag wall, on the one hand influence ash-removal effect, cause filter bag damage on the other hand and large tracts of land is changed filter bag.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of pulse bag type dust collector that has the annular space injector, and the ring-type air pulse of formation can not damage filter bag, prolongs life of bag filter effectively.

The technical scheme that the utility model technical solution problem adopts is: a kind of pulse bag type dust collector that has the annular space injector, comprise ash bucket, filter chamber, air-purifying chamber, air inlet, air outlet, be provided with porous plate between described filter chamber and the air-purifying chamber and be used to install filter bag, on described porous plate, be provided with the annular space pulse ash remover.

As further improvement, described annular space pulse ash remover comprises insertion pipe, annular space injector, electromagnetic impulse valve, branch gas bag, and is interconnected successively, and described annular space injector comprises interface, blow vent, annular housing, annulus; The bottom of described annular space injector is in the filter bag.

The beneficial effects of the utility model are: be provided with the annular space pulse ash remover between porous plate and filter bag, when deduster needs deashing, provide compressed air source by a minute gas bag, electromagnetic impulse valve discharges air pulse, air pulse enters blow vent, the annular housing of annular space injector by insertion pipe, sprays from the annulus, and the ring-type high velocity air of formation reaches the effect of deashing along the ejection of filter bag inwall, because the ring-type high velocity air can not damage filter bag, prolongs life of bag filter effectively.And this device is easy for installation, reliable operation, easily maintenance.
