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
