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.

Dust removing apparatus

A steel tube working apparatus is composed of a clamping device consisting of a pair of clamps, a pair of projecting plates, means for actuating the clamps and the projecting plates, a pair of guide bars and a main body frame; a base plate having a pair of guide rollers fitting to the guide bars fixedly secured to its opposite ends; and working means connected to the base plate in a movable and rotatable manner. A cutting device, a beveling device, a welding device, etc. are selectively connected to the base plate as the working means.
