Description

上記課題を解決するために、本発明の船舶は以下の手段を採用する。
すなわち、本発明にかかる船舶は、船舶推進用の内燃機関本体と、該内燃機関本体からの排気ガスによって駆動されるタービン、及び、該タービンに連結されるとともに吸気を圧縮するコンプレッサを有する過給機と、前記内燃機関本体からの排気ガスが導かれる排気ガス経路と、前記排気ガス経路から分岐され、排気ガスの一部を前記内燃機関本体の吸気経路に導くＥＧＲ経路と、該ＥＧＲ経路に設けられ、ベンチュリスクラバとされたＥＧＲ排気ガス洗浄装置とを備え、前記ベンチュリスクラバは、鉛直上方に設けられた上部大径部と、前記上部大径部の下方に設けられ流れ方向に流路断面積が漸次減少する縮小テーパ部と、前記縮小テーパ部の下方に設けられたスロート部と、前記スロート部の下方に設けられ流れ方向に前記流路断面積が漸次増大する拡大テーパ部と、前記拡大テーパ部の下方に設けられた下部大径部とを備え、前記上部大径部には、スプレーノズルが設けられ、前記スプレーノズルから吸収液が前記縮小テーパ部と前記スロート部との接続位置に向かって噴霧されることを特徴とする。 In order to solve the above problems, the ship of the present invention employs the following means.
That is, a ship according to the present invention is a supercharger having an internal combustion engine body for propulsion of a ship, a turbine driven by exhaust gas from the internal combustion engine body, and a compressor connected to the turbine and compressing intake air. An exhaust gas path through which the exhaust gas from the internal combustion engine body is guided, an EGR path branched from the exhaust gas path and leading a part of the exhaust gas to the intake path of the internal combustion engine body, and the EGR path An EGR exhaust gas cleaning device provided as a venturi scrubber , wherein the venturi scrubber is provided with an upper large-diameter portion provided vertically upward and a flow passage cut in the flow direction provided below the upper large-diameter portion. A reduced taper portion having an area that gradually decreases, a throat portion provided below the reduced taper portion, and a flow path cross section provided in the flow direction provided below the throat portion. An enlarged taper portion that gradually increases and a lower large-diameter portion provided below the enlarged taper portion, and a spray nozzle is provided in the upper large-diameter portion, and the absorbing liquid is reduced from the spray nozzle. It sprays toward the connection position of a taper part and the said throat part, It is characterized by the above-mentioned.
