The present invention addresses the problem of providing a technique with which it is possible to wash contaminants in a seawater passage including a scrubber with a simpler configuration. In order to solve this problem, an exhaust gas purification device (1) according to one embodiment of the present disclosure is provided with a scrubber (10) that purifies exhaust gas from a main engine (100) of a ship using seawater. And an external drainage introduction unit (70) that introduces, into the scrubber (10), alkali drainage having a relatively high pH (hydrogen ion index) or alkalinity, said alkali drainage being discharged from a boiler (200) and a fresh water generator (300) mounted on the ship.
本发明的课题在于提供以更简易的构成,能够洗涤包含洗涤器的海水通路中的污染物的技术。为了解决该课题,本公开的一实施方式涉及的排出气体净化装置1具备使用海水,将船舶的主机发动机100的排出气体进行净化的洗涤器10,以及将从船舶所搭载的锅炉200、造水装置300排出的、pH(氢离子指数)或碱度相对高的碱排水导入至洗涤器10的外部排水导入部70。
