FILTER FOR GAS PURIFICATION Russian patent published in 2009 - IPC B01D46/02 

FIELD: mechanics.

SUBSTANCE: invention refers to field of gas purification from solid impurities. Filter contains chambers of pure and contaminated gas separated by partition, at least two vertically oriented filtering elements with frames in the form of parallelepiped arranged in pairs in rows in chamber of contaminated gas and their open ends are secured in square holes of partition by attachment devices, assembled in chamber of pure gas, system of pulse regeneration of filtering elements including blow-off pipes installed from side of filtering elements open ends in chamber of pure gas containing jets directed to filtering elements and connected to receiver: each pipe - by separate pneumatic valve, control unit of pulse regeneration system and fan. Frames of filtering elements are made of perforated sheets, filtering elements are installed by means of attachment devices made in the shape of bracket with two attachment points of filtering elements made in the shape of grooves of flat-topped profile, and containing in their middle part two arresters for bracket mounting installed at right angle to bracket and rigidly fixed on it by means of couple of planes, blow-off pipes are connected in pairs by means of two planes.

EFFECT: compactness, design simplicity, reduction of its production and operation expenses.
