To provide a ship desulfurization system capable of lowering the temperature of exhaust gas introduced into an exhaust gas introduction part, and at the same time reducing the volume of the exhaust gas introduced into the exhaust gas introduction part.SOLUTION: The ship desulfurization system desulfurizes exhaust gas exhausted from exhaust gas generation equipment onboard a ship, comprises: an absorption tower which defines the internal space and includes an absorption tower main body in which is formed an exhaust gas introduction port in communication with the internal space and an exhaust gas introduction part connected to the exhaust introduction port; and an exhaust gas cooling device which can spray cooling water on exhaust gas introduced into the exhaust gas introduction part before the exhaust gas introduced into the internal space. The exhaust gas cooling device includes cooling water nozzles configured to blow out the cooling water toward an upstream side in an exhaust gas flow direction.SELECTED DRAWING: Figure 19

    【課題】排ガス導入部内に導かれた排ガスの温度を下げることができるとともに、排ガス導入部内に導かれた排ガスの体積を小さくできる船舶用脱硫装置を提供する。【解決手段】船舶に搭載される排ガス発生装置から排出される排ガスを脱硫するための船舶用脱硫装置であって、内部空間を画定するとともに内部空間と連通する排ガス導入口が形成された吸収塔本体部、及び、排ガス導入口に接続される排ガス導入部、を含む吸収塔と、排ガス導入部に導入され、内部空間に導入される前の排ガスに対して冷却水を散布可能な排ガス冷却装置と、を備え、排ガス冷却装置は、冷却水を排ガスの流れ方向の上流側に向かって噴出するように構成されている冷却水ノズルを有する。【選択図】 図19
