To provide an exhaust gas purification device capable of curbing generation of a deposit and thereby curbing reduction in performance of the exhaust gas purification device and an engine due to the deposit.SOLUTION: An exhaust gas purification device is installed on an exhaust passage of an engine stored in an engine room compartmentalized in a vessel body and is configured to remove at least nitrogen oxide from exhaust gas discharged from the engine. The exhaust gas purification device has: a catalyst section which includes a selective reduction catalyst to selectively reduce the nitrogen oxide; a reducing agent addition device which is configured to add a reducing agent to the exhaust gas at an upstream side of the catalyst section in a flow direction of the exhaust gas; and a casing which is configured to store the catalyst section and installed at least partially in the engine room.SELECTED DRAWING: Figure 2

    【課題】析出物の発生を抑制することができ、析出物による排ガス浄化装置やエンジンの性能低下を抑制することができる排ガス浄化装置を提供する。【解決手段】船体の内部に区画される機関室に設けられるエンジンの排気流路に設けられ、且つ、エンジンから排出された排ガスから少なくとも窒素酸化物を除去するように構成される排ガス浄化装置であって、窒素酸化物を選択還元するための選択還元触媒を含む触媒部と、触媒部よりも排ガスの流れ方向の上流側の排ガスに還元剤を添加するように構成される還元剤添加装置と、触媒部を収納するように構成されるケーシングであって、機関室内に少なくとも一部が配置されるケーシングと、を備える。【選択図】 図2
