Multi-stage deodorizer for reuse of cleaning solution

The present invention relates to a multi-stage deodorizer for reusing cleaning liquid, which comprises: a main body including an inlet for receiving odor gas and an outlet for discharging the treated clean gas and having a first-stage filter medium and second-stage filter medium installed on the front and rear side in a movement path from the inlet to the outlet to deodorize the odor gas, respectively; a first-stage injection nozzle and second-stage injection nozzle installed to spray a cleaning liquid to the first-stage filter medium and the second-stage filter medium in the main body, respectively; a first-stage washing tank collecting the cleaning liquid sprayed from the first-stage injection nozzle and falling from the first-stage filter medium; a second-stage washing tank collecting the cleaning liquid sprayed from the second-stage injection nozzle and falling from the second-stage filter medium and receiving water through a water supply line so that water supply to the first-stage washing tank depends on the second-stage water tank; a first-stage circulation line for supplying the cleaning liquid from the first-stage washing tank to the first-stage injection nozzle; and a second-stage circulation line including a supply line for supplying the cleaning liquid from the second-stage washing tank to the second-stage spray nozzle and supplying the cleaning liquid to the first-stage washing tank. According to the present invention, since the clean cleaning liquid of the second-stage washing tank is transferred to and reused in the first-stage washing tank, the amount of supplied water and the amount of generated wastewater are reduced, thereby reducing water costs and wastewater treatment costs. In the case of a chemical cleaning type deodorizer in which chemicals are injected into the cleaning liquid, active chemical components contained in the second-stage cleaning liquid are reduced, thereby reducing chemical costs. 본 발명은 악취가스가 유입되기 위한 유입구와 처리를 마친 청정가스의 배출구가 각각 마련되고, 상기 유입구로부터 상기 배출구까지의 이동경로에 악취가스를 탈취시키기 위한 1단충전여재와 2단충전여재가 전후로 각각 설치되는 본체; 상기 본체 내에서 상기 1단충전여재와 상기 2단충전여재 각각에 대하여 세정액을 분사하도록 설치되는 1단분사노즐 및 2단분사노즐; 상기 1단분사노즐로부터 분사되어 상기 1단충전여재로부터 낙하하는 세정액을 수집하는 1단세정조; 상기 2단분사노즐로부터 분사되어 상기 2단충전여재로부터 낙하하는 세정액을 수집하고, 급수라인을 통해 물을 공급받도록 하여, 상기 1단세정조가 급수를 의존하는 2단세정조; 상기 1단세정조로부터 세정액을 상기 1단분사노즐에 공급하도록 하는 1단순환라인; 및 상기 2단세정조로부터 세정액을 상기 2단분사노즐에 공급하도록 하되, 상기 1단세정조에도 공급하기 위한 공급라인을 가지는 2단순환라인;을 포함하도록 한 세정액 재이용 다단 탈취기에 관한 것이다. 본 발명에 따르면, 청정한 2단세정조의 세정액을 1단세정조로 이송하여 재이용함으로써,
