Disclosed is an exhaust gas processing system of a ship, capable of improving efficiency in processing equipment. According to one embodiment of the present invention, the exhaust gas processing system of a ship comprises: a first scrubber spraying first cleaning water to first exhaust gas of the ship to generate an inert gas; a storage unit to store second cleaning water; a second scrubber receiving the second cleaning water from the storage unit to spray the same to second exhaust gas; a first control valve disposed on a first supply line to supply the first cleaning water to the first scrubber; a first connection line interconnecting the first control valve with a second supply line which connects the storage unit and the second scrubber to circuit the second cleaning water; a second control valve disposed on a discharge line to discharge the first cleaning water passed through the first scrubber to the outside; and a second connection line to connect the second control valve and the storage unit. When the ship reaches an emission prohibited area, the second cleaning water supplied from the storage unit by the first control valve is supplied to the first scrubber and the first cleaning water passed through the first scrubber is supplied to the storage unit by the second control valve.
선박의 배기가스 처리 시스템이 개시된다. 본 발명의 실시 예에 따른 선박의 배기가스 처리 시스템은 선박의 제1배기가스에 제1세정수를 분사하여 불활성가스를 생성하는 제1스크러버; 제2세정수를 저장하는 저장부; 저장부로부터 제2세정수를 공급받아 제2배기가스에 분사하는 제2스크러버; 제1스크러버로 제1세정수를 공급하는 제1공급라인 상에 마련된 제1제어밸브; 제1제어밸브와 제2세정수가 순환하도록 저장부 및 제2스크러버를 연결하는 제2공급라인을 서로 연결하는 제1연결라인; 제1스크러버를 거친 제1세정수를 외부로 방출하는 방출라인 상에 마련된 제2제어밸브; 제2제어밸브와 저장부를 연결하는 제2연결라인;을 포함하되, 선박이 배기가스 배출 제한구역에 도달한 경우, 제1제어밸브에 의해 저장부로부터 공급된 제2세정수가 제1스크러버로 공급되고, 제2제어밸브에 의해 제1스크러버를 거친 제1세정수가 저장부로 공급되도록 한다.
