To provide a ship desulfurization system capable of suppressing the effects of a problem that spraying of a washing liquid becomes ununiform due to pitching and rolling of the ship.SOLUTION: The ship desulfurization system desulfurizes exhaust gas exhausted from exhaust gas generation equipment onboard a ship, comprises: an absorption tower which defines an internal space having a lengthwise direction and includes an absorption tower main body in which is formed an exhaust gas introduction port at one end in the lengthwise direction in communication with the internal space; an exhaust gas introduction device which introduces exhaust gas exhausted from the exhaust gas generation equipment to the absorption tower main body; and a spraying device which can spray a washing liquid on exhaust gas flowing through the internal space. The spraying device includes a water spray pipe extending through the internal space and a plurality of spray nozzles provided on the spray water pipe spaced apart at a given interval. When a maximum length of the internal space in the lengthwise direction is taken as L, and a maximum width on the internal space in a short direction orthogonal to the lengthwise direction is taken as W, the ratio W:L is more than 1:1.1 but not exceeding 1:6.0.SELECTED DRAWING: Figure 5

    【課題】船舶の動揺に起因して洗浄液の散布が不均一になる不具合の影響を抑制することが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、長手方向を有する内部空間を画定するとともに、長手方向における一方側の端部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、を含む吸収塔と、排ガス発生装置から排出される排ガスを吸収塔本体部に導くための排ガス導入装置と、内部空間を流れる排ガスに洗浄液を散布可能な散布装置と、を備えている。そして、散布装置は、内部空間に延在する散水管と、散水管に所定間隔を開けて配置された複数の散水ノズルと、を有し、内部空間の長手方向の最大長さをL、内部空間の長手方向に対して直交する短手方向の最大幅をW、とした場合に、W:Lが1:1.1超、且つ、1:6.0以下の範囲である。【選択図】 図5
