본 발명은, 선박 거주구 에어컨의 드레인 워터를 이용하여 요소수 온도를 저감시키는 선박용 SCR 시스템이 제공하기 위한 것으로, 본 발명의 일 실시예에 따른 선박용 SCR 시스템은 선박의 메인엔진, 상기 메인엔진의 연소 중 발생한 배기가스가 포집되는 배기가스 리시버, 상기 배기가스 리시버의 후단에 배치되어 SCR 촉매 반응에 의해 상기 배기가스 중의 질소산화물(NOx)를 저감하는 SCR 반응기, 상기 SCR 반응기 측으로 SCR 촉매 반응을 위해 공급되는 요소수를 저장하는 저장 탱크, 선박 거주구에 사용되는 에어컨의 드레인 워터(drain water)로 상기 저장 탱크의 요소수의 온도를 저감시키는 냉각부를 포함할 수 있다.

    The present invention is to provide an SCR system for ships that reduces a urea water temperature by using drain water of a residence air conditioner of a ship. The SCR system for ships according to an embodiment of the present invention comprises: a main engine of a ship; an exhaust gas receiver in which exhaust gas generated during combustion of the main engine is collected; an SCR reactor disposed at the rear end of the exhaust gas receiver to reduce nitrogen oxides (NOx) in the exhaust gas by SCR catalytic reaction; a storage tank for storing the urea water supplied for the SCR catalyst reaction to the SCR reactor side; and a cooling unit for reducing the temperature of the urea water in the storage tank by using drain water of the air conditioner used in the ship residence.
