FILTER-SORBER Russian patent published in 2009 - IPC B01D53/04 

FIELD: filters.

SUBSTANCE: invention relates to sorption filters for purification of technological air media. Filter-sorber consists of cylindrical body, bottom, lid, lower and upper cassette plates, input and output branch pipes. Filter-sorber contains at least one cylindrical shell filled with sorbate, located vertically inside cylindrical body, installed between lower and upper cassette plates resting in them with butt end parts. Input and output branch pipes are installed on cylindrical body above upper and under lower cassette plates respectively. In input chamber formed by upper cassette plate, upper part of cylindrical body and lid, on upper cassette plate upper cylindrical insert is installed. In output chamber formed by lower cassette plate, lower part of cylindrical body and bottom, on lower cassette plate lower cylindrical insert is installed. Distance between lid and upper cylindrical insert increases as it goes farther on perimeter from input branch pipe, and distance between bottom and lower cylindrical insert grows on its perimetre as it goes farther from input branch pipe. Upper cylindrical insert is made perforated.

EFFECT: increase of efficiency of purification of gas flow from admixtures.
