To provide desulfurization device capable of removing sulfur oxide in exhaust gas discharged from a ship engine and of avoiding an adverse effect on the engine by suppressing an energy loss.SOLUTION: A packed bed formed in a rectangular cylindrical-shape reaction vessel, is filled with a desulfurizing agent and arranged so that an exhaust gas flows from one side to the other side of the packed bed. An example uses a packed bed 2 formed in a circular cylindrical-shape having a central axis coincide with a central axis of a reaction vessel 1, and the device of the invention is configured as a radial flow-type device in which the exhaust gas flows from an outer peripheral side to an inner peripheral side of the packed bed 2. Another example may use a flat plate-shape packed bed arranged parallel to a side surface of the reaction vessel 1 and for example, the device is configured so that two packed beds are mutually spaced apart and connected with each other in parallel.SELECTED DRAWING: Figure 1

    【課題】船舶のエンジンから排出される排ガス中の硫黄酸化物を高い除去率で除去することができ、しかも圧力損失を抑えてエンジンに対する悪影響を避けることができる脱硫装置を提供すること。【解決手段】角筒形状の反応容器内に脱硫剤を充填して形成される充填層を、充填層の一面側から他面側に排ガスが流れるように配置する。一例として反応容器1の中心軸を中心軸とする円筒形状に形成された充填層2が用いられ、充填層2の外周面側から内周面側に排ガスを通流するラジアルフロー型として装置が構成される。また他の例として反応容器1の側面に平行に平板形状の充填層を用いてもよく、例えば2個の充填層を互に間隔をおいて配置し、これらの充填層が並列に接続されるように構成する。【選択図】図1
