SECTIONAL SLEEVE FILTER FOR PURIFYING OF GAS Russian patent published in 2008 - IPC B01D46/02 

FIELD: metallurgy.

SUBSTANCE: invention opens up a sectional sleeve filter used for purifying of gas that contains frame equipped with the brining and excurrent junction pipes and divided for chambers where the polluted or clean gases may be stored. The invention has sleeves with the filter surface that is made from fabric; system of an impulse regeneration of these sleeves; and system of discrepancy detection developed for the sleeves' filter surface. Specifically, the aforementioned detection system includes ejector, transducer unit that determines a quantity of dust, and junction pipes. The transducer is made as a chamber equipped with transparent side walls and is located between sources of light and a photo element. The filter is distinguished for its chamber of purified air which, in turn, is divided in sections linked to the brining junction pipe with the gas flues. A gas flue of each section is equipped with a cutoff plate, and the discrepancy detection system in the sleeves' filter surface is installed in every section. The ejector is actually set inside the gas flue, while its bringing and excurrent junction pipes are located outside the gas flue exit. The ejector's receiving junction pipe is connected with the dust transducer. The transducer's excurrent junction pipe is linked to the gas flue, while the sensory device itself is equipped with a junction pipe which stipulates an entrance of the regenerative air.

EFFECT: facilitation of the construction's simplification and increases in the reliability of the filter's work.
