The present invention relates to an apparatus for processing an exhaust gas of a ship, which improves sulfur oxides removal efficiency and does not require an additional facility to manufacture a scrubbing solution by applying de-ballasted water discharged from a ballast water tank as a scrubbing solution of a wet scrubber. The apparatus for processing the exhaust gas of the ship according to the present invention includes: a scrubber which removes nitrogen oxides or 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; an SCR device which removes nitrogen oxides remaining in the exhaust gas discharged from the scrubber through selective catalytic reduction reaction; a ballast water processing apparatus for producing ballast water including electrolyzed water; and a scrubbing solution supply pipe which has one end connected to a deballasting pipe of the ballast water processing apparatus, and has the other end connected to the scrubber, and supplies the ballast water discharged through the deballasting pipe as the scrubbing solution of the scrubber.

    본 발명은 평형수 탱크에서 배출되는 디발라스트수(de-ballasted water)를 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, 상기 스크러버로부터 배출되는 배기가스에 잔류하는 질소산화물을 선택적촉매환원 반응을 통해 제거하는 SCR 장치와, 전기분해수가 포함된 평형수를 생산하는 평형수 처리장치 및 일단이 상기 평형수 처리장치의 디발라스팅 배관과 연결되고, 다른 일단이 상기 스크러버와 연결되어, 상기 디발라스팅 배관을 통해 배출되는 평형수를 상기 스크러버의 스크러빙 용액으로 공급하는 스크러빙 용액 공급배관을 포함하여 이루어지는 것을 특징으로 한다.
