COLUMN FOR FLUE GAS COMPLEX TREATMENT Russian patent published in 2011 - IPC B01D53/46 

FIELD: process engineering.

SUBSTANCE: invention may be used in heat engineering. Proposed column comprises casing 1 representing rectangular box 2 with detachable front wall 3 with its top accommodating air discharge slits, and rear wall 5 with intake air slits. Said rectangular box 2 is closed from below by flat-pyramid bottom 7 with detachable cup and, from above, by prismatic cover 9 that houses damper 10 provided with inlet 11 and outlet 12 branch pipes communicated with heat generator gas duct. Casing 1 is divided by vertical baffle 13 to form opening 14 nearby bottom and to divide casing 1 into first section I accommodating first treatment stage and second section II accommodating second and third treatment stages. First, second and third treatment stages consist of vertical perforated cartridges 15, 17 and 18, respectively. First treatment stage cartridges are filled with particles of crushed lime hydrate (Ca(OH)₂), second treatment stage cartridges are filled with active carbon particles, while third treatment stage is filled with metal screen coated by paraffin layer.

EFFECT: partial leaning of flue gas of nitrogen oxides, carbon oxides, carbon dioxide, organic impurities and solid suspensions.
