摘要： A dust removing apparatus suppresses pressure and temperature variations of cleaned gas to facilitate the removal of dust. A clean gas chamber delimited by a plurality of porous ceramic tubular filter elements is divided in two by a partition wall. The respective chambers are connected through discrete outlet pipes to a clean gas main pipe, and backwashing devices are provided in the respective outlet pipes. Furthermore, a porous ceramics filter element is provided on a bottom partition plate so that the gas flow velocity in the tubular filter elements can be insured to prevent dust from adhering thereto.
