| titleOfInvention | Treatment method for purifying sewage and tail gas from furnace gas in acid production from gypsum |
| abstract | A treatment method for purifying sewage and tail gas from the furnace gas in the acid production from gypsum, belonging to the field of industrial sewage and waste gas treatment, is mainly divided into purification system acidic sewage circulation, sulfuric acid system acidic sewage treatment circulation and sulfuric acid system tail gas treatment circulation. The method uses the acidic sewage generated by the purification system acidic sewage circulation as the raw material of the sulfuric acid system acidic sewage treatment station, uses the solid generated by the sulfuric acid system acidic sewage treatment station as the raw material for the acid production from gypsum, and uses the alkaline sewage generated by the sulfuric acid system acidic sewage treatment circulation as the desulfurizer of the tail treatment step. The invention solves the treatment problem of the acidic sewage from the acid production from gypsum, realizes the cyclic utilization of the purification system washing acidic sewage, and reduces desulfurization cost through using the sewage after being subject to neutralizing treatment as the desulfurizer for the tail gas treatment. |
