FIELD: process engineering.
SUBSTANCE: invention relates to aspiration air filtration. Proposed filter comprises two dust collecting chambers with filter sleeves, contaminated air feed pipelines, inlet chamber with twin deflecting screen, cleaned and additionally cleaned air chambers, one-row panel of air cell-type filters to form chambers of additional dust separation below said panel and chambers of additionally cleaned air above said panel, mechanisms of recovery, filter sleeve recovery control mechanisms and said panel of air cell-type filters, bins, manifolds of additionally cleaned air discharge, inspection chambers, air ducts, and radial-flow blowers. Additional dust separation chamber is divided by dead partition separating the panel of air cell-type filters into two sections to form second chamber of additional dust separation.
EFFECT: lower operating costs and higher efficiency.
