Abstract
The invention discloses a bag-type dust collector with a dust collecting device. The bag-type dust collector comprises a dust collector shell, wherein a lap of conducting film layer is arranged on the inner wall of the dust collector shell; the upper edge of the conducting film layer is connected with an annular baffle plate; a water spray pipe is arranged on the outer wall of the dust collector shell corresponding to the annular baffle plate; a metal lead is arranged in the dust collector shell; the conducting film layer and the metal lead are respectively conducted and connected with high-voltage positive and negative electrodes; and the lower part of an ash bucket is communicated with a blow-off pipe. The electrostatic dust collection is performed for smoke to prevent the blockage of a dust collecting bag, so that the filter speed is largely quickened, the ageing of the dust collector is slowed down, and the service life is prolonged; and water sprayed by an opening of the water spray pipe in the annular baffle plate flows down along the inner wall of the conducting film layer to flush dust particles bonded on the inner surface of the conducting film layer, so that the dust particles drop in the ash bucket along with the water current, and are discharged along with the blow-off pipe, the pollution discharge is convenient, and the blockage of the ash bucket by the dust particles is prevented.
Description
Technical field
The present invention relates to dust arrester technical field, especially for a kind of sack cleaner with dust collecting.
Background technology
In environmental protection industry (epi), mainly setting of the fume treatment that sack cleaner produces when being and process all kinds of boilers, incinerator burning
Standby, cleaner unit body construction be roughly divided into ash bucket, blast pipe, raising middle flask, top box, discharge pipe, bypass airduct, injection tube,
Defecator etc., its concrete principles illustrated: flue gas, under blower negative pressure, enters cleaner unit through air inlet main pipe and air intake short tube
In housing, coarse powder dirt falls into ash bucket, and fine dust rises in raising middle flask with air-flow, overworks filter cloth in raising middle flask, and air-flow passes
Fine dust in flue gas is trapped on filter cloth outer surface by filter cloth, and the pure air after filtration enters upper box, until
Discharge pipe, dust removal process terminates.When fine dust on filter cloth outer surface is attached to a certain amount of, injection tube is by release height
Pressure gas stream winding-up filter cloth, blows off the fine dust on filter cloth outer surface in ash bucket.
Conventional cleaner unit shell not lacks dust collection function, and coarse powder dirt stops inwall landing with cleaner unit shell under gravity
Enter in ash bucket, but the fine dust on filter cloth outer surface be under injection tube is jetted, and flies away everywhere in shell of dust remover,
