FIELD: process engineering.
SUBSTANCE: invention relates to chemistry and may be sued for cleaning flue gas of residential heat supply systems. Proposed column comprises box with jointing assemblies 2, and bottom communicated via hydraulic lock 16 with drain pipeline 15. Said box accommodates first and second treatment stages made up of vertical perforated cartridges consisting of flanged vertical perforated wall with bottom and perforated detachable wall with detachable lateral cover made from rustproof material filled with crushed lime hydrate (Ca(OH)2) and crushed activated carbon arranged inside gas ducts 10 separated by vertical baffles from air ducts 11 connected, at their bottom, with intake slots 12 to make plate heat exchanger. Holes of perforated vertical cartridges of the first and second stages are rectangular and arranged in vertical lines wherein each hole, in turns, incorporates guide and ejecting plates arranged at 45° and attached to top and bottom edges of wall holes.
EFFECT: higher efficiency of gas treatment.
