Description

Movable face sealing method Technical Field The invention relates to the technical field of environment-friendly ash removal of bag-type dust collectors, in particular to a movable face sealing method. Background With the increase of environmental protection requirements, more and more dust removal equipment is used for the production and the living of various industries, and a bag-type dust remover is the main force in the dust remover. The back blowing ash removing system of the bag dust remover always adopts a pulse ash removing mode, the air compressor produces compressed air, the compressed air is injected into the air storage tank through a pipeline, and when the bag ash removing operation is carried out, the compressed air respectively passes through the pipeline, the air bag, the electromagnetic pulse valve, the blowing pipe and the venturi tube to finish the back blowing ash removing operation.
