FIELD: chemistry. ^ SUBSTANCE: processing blasting air and flue gases occurs in the device, which includes a heat exchange and absorptive-heat exchange sections. Water vapour condenses during the cooling of flue gases lower than the dew-point. The cooled flue gases are mixed up with the ozone-air mixture. Oxides of nitrogen and sulfur (NOx and SOx) are oxidized to NO2 and SO3 and absorb the obtained condensate in the plate-type heat exchanger 1st step 27. In the lower block of gas cleaning 28 filled with a crumb of slaked lime, neutralizes NO and NO2. In the upper block of the gas cleaning 29 filled with a crumb of activated coal, adsorbs carbon monoxide and unburned fuel. After the heat exchanger of the 2nd step 11 heated air in the block of regeneration 5 is desorbed from the activated coal CO and the unburned fuel. Enriched gases heated air is directed to the furnace of a boiler. ^ EFFECT: declared invention provides an increase ecological and economic efficiency of process of cleaning of flue gases. ^ 2 cl, 7 dwg |
