Method and apparatus for purifying exhaust gas of ship and ship using the same

The present invention relates to a purification apparatus (100) of exhaust gas for a ship, which collects carbon dioxide and sulfur dioxide included in the exhaust gas generated from the ship by using a reactive solution, converts the carbon dioxide and sulfur dioxide into a material that does not affect environment, stores the same, and then transports the same to the land, and to a purification method of the exhaust gas for the ship using the same. The purification method comprises the following steps of: generating carbonic acid by reacting the carbon dioxide with water; generating sulfurous acid and sulfuric acid by reacting the sulfur dioxide with water; generating the reactive solution including inorganic salt; regenerating the reactive solution while generating carbonate and sulfate; and separating the carbonate and sulfate from the reactive solution. 본 발명은 선박에서 발생되는 배기가스에 포함된 이산화탄소와 이산화황을 반응액을 사용하여 포집하고, 상기 이산화탄소와 이산화황을 환경에 영향을 주지 않는 물질로 전환하여 저장한 후 육상으로 이송할 수 있는 선박용 배기가스 정화장치(100) 및 이를 이용하는 선박 배기가스 정화방법에 관한 것이다
