Abstract

PURPOSE: To lessen the number of attendant facilities for simplifying a desulfurization apparatus by a method in which SO2 in waste gas in adsorbed on activated carbon in the presence of water, O2 and NH3 gas, and then the activated carbon used in treatment is reacted with lime stone to convert SO2 into gypsum which is in turn recovered.
CONSTITUTION: Waste gas 2 is introduced into the lower part of a moving bed type adsorption tower 3 where it is brought into contact with activated carbon in a counterwise manner. SO2 is then converted into dilute sulfuric acid with moisture and O2 present in the waste gas and the dilute sulfuric acid is reacted with NH3 gas 11 from a reactor tank 4 and adsorbed in the form of (NH4)2SO4. Then, the activated carbon used is sent to the reactor tank 4 where it is reacted with water 5 and lime stone 6 suppled there to form gypsum and NH3 gas which is in turn recycled to the adsorption tower 3 for reuse. Slurried gypsum and activated carbon are screened in a separation tower 7 and the gypsum 8 is dried and stored. The activated carbon 9 washed with sprayed water to remove adhered gypsum is dried in a preheater 10 and then recycled to the adsorption tower 3 for reuse. The gas 12 deprived of SO2 is released through a dust collector 13.
