AIR CLEARING ECOLOGICAL SYSTEM FILTRATION ASSEMBLY Russian patent published in 2008 - IPC B01D46/00 

FIELD: engines and pumps.

SUBSTANCE: invention is designed to clear air of harmful impurities. The proposed assembly incorporates two filtration-clearing elements accommodated inside the said assembly housing in layers filled with dust catching filtration material, sorbents and absorbers. The split assembly is made up of two separate housings consisting of gas-tight side walls, gas-tight inlet and outlet walls arranged vertically relative to the purified air flow. The housing arranged first along the air flow accommodates the corrugated filtration paper, the second housing is furnished with at least two layers, one filled with a coal- and/or coal modification-based sorbent and the other one representing a filler made in potassium, and/or calcium and/or or barium permanganate. A spacing material is proved between the absorber, sorbent and gas-tight walls. The first housing front walls feature larger sizes than those of the second housing walls. The ledges representing the plates are arranged on the opposite sides of the first housing side walls to face the purified air flow and to attach the first housing to the ecological system housing, the said ledges being interconnected by a rigid cross piece fitted above the filtration material and the tight spacer being provided between the housings.

EFFECT: cleared air in living quarters.
