DUST SEPARATOR APPARATUS WITH A NOISE ATTENUATION DEVICE

摘要

A dust separator apparatus having a housing defining a converging dirty gas passage with a dirty gas inlet at one end and a particulate matter outlet at the other end. One wall of the housing is louvred to effect particulate matter separation from a dirty gas stream flowing through the dirty gas passage. A plurality of projections extend into the converging dirty gas passage to create turbulent flow in the dirty gas stream flowing through the converging dirty gas passage and attenuating noise created by the gas stream.
