To provide an exhaust gas treatment device having a structure that is less affected by vibration and achieving excellent durability.SOLUTION: An exhaust gas treatment device 1 is mounted on a ship S with an engine E and places sea water W in contact with an exhaust gas Eg that passes through a flow space 10s in an exhaust tower 10 to perform treatment. In the exhaust tower, a trunk pipe 21 and branch pipes 23, which extend into the flow space and are supplied with the sea water, and injectors 25, which are installed at the branch pipes and inject the supplied sea water into the flow space, are disposed. A cross section of the branch pipe, which is orthogonal to a supply passage of a pipe member forming a sea water supply passage, is formed into an ellipse so that a vibration direction of vibration V transmitted from the engine is set to a long axis to make rigidity of the long axis against the vibration V higher than those of short axes set in other directions.SELECTED DRAWING: Figure 1

    【課題】振動の影響を受け難い構造の耐久性に優れる排ガス処理装置を提供すること。【解決手段】エンジンEと共に船舶Sに搭載されて、排気塔10内の流動空間10sを通過させる排ガスEgに海水Wを接触させて処理する排ガス処理装置1であって、排気塔は、流動空間内に延長されて海水を供給される幹配管21および枝配管23と、枝配管に設置されて供給される海水を流動空間内に噴射する噴射器25とが配置されて、枝配管は、海水の供給流路を形成する配管部材の供給流路に対する直交断面形状が、エンジンから伝搬してくる振動Vに対する振動方向を長軸として剛性が他の方向の短軸よりも高くなるように楕円形に形成されている。【選択図】図1
