본 발명은 선박 평형수 처리장치에서 생성되는 전기분해수를 습식 스크러버의 스크러빙 용액으로 적용함으로써 황산화물 제거효율을 향상시킴과 함께 스크러빙 용액 제조를 위한 별도의 설비가 요구되지 않는 선박 배기가스 처리장치에 관한 것으로서, 본 발명에 따른 선박 배기가스 처리장치는 엔진 배기가스를 스크러빙 용액과 접촉시켜 엔진 배기가스에 포함되어 있는 질소산화물 및 황산화물을 환원반응 또는 산화반응을 통해 제거하는 스크러버와, 해수, 전기분해수, 해수와 전기분해수가 혼합된 평형수가 이동되는 배관을 구비한 평형수 처리장치 및 일단이 상기 평형수 처리장치와 연결되고, 다른 일단이 상기 스크러버와 연결되어, 상기 평형수 처리장치의 해수, 전기분해수, 해수와 전기분해수가 혼합된 평형수 중 어느 하나를 상기 스크러버의 스크러빙 용액으로 공급하는 스크러빙 용액 공급배관을 포함하여 이루어지는 것을 특징으로 한다.
The present invention relates to an apparatus for purifying an exhaust gas of a ship, which can improve sulfur oxides removal efficiency and does not require an additional facility to manufacture a scrubbing solution by applying electrolyzed water generated in a ship ballast water processing apparatus as the scrubbing solution of a wet scrubber. The apparatus for purifying the exhaust gas of the ship according to the present invention includes: a scrubber which removes nitrogen oxides and sulfur oxides included in an engine exhaust gas through reduction reaction or oxidation reaction by making the engine exhaust gas come in contact with the scrubbing solution; a ballast water processing apparatus which comprises a pipe where seawater, electrolytic water and the ballast water mixed with the seawater and the electrolytic water flow; and a scrubbing solution supply pipe which has one end connected to the ballast water processing apparatus, and has the other end connected to the scrubber, and supplies one among the seawater, the electrolytic water and the ballast water mixed with the seawater and the electrolytic water of the ballast water processing apparatus as the scrubbing solution of the scrubber.
