EXHAUST GAS PURIFICATION DEVICE FOR MARINE DIESEL ENGINE THAT USES LOW-QUALITY FUEL CONTAINING HIGH CONCENTRATION OF SULFUR COMPONENT

WIPO Patent Application WO/2015/156290

A1

Provided is an exhaust gas purification device that is for a marine diesel engine and that makes it possible to discharge treated waste water into the ocean whether sailing within or outside of a sea area in which special regulations regarding treated water are in effect, particularly when used in a marine diesel engine that uses low-quality fuel such as a heavy oil that contains a high concentration of a sulfur component. This exhaust gas purification device that is for a marine diesel engine that uses a low-quality fuel comprising a high concentration of a sulfur component is characterized by a configuration in which: a selective catalytic reduction denitration device (abbreviated as "SCR" below) is provided to an exhaust pipe that is connected to the exhaust manifold of an engine; and a scrubber that uses the difference in the diffusion velocities of gas and particles and that hardly removes any of the PM that is included in exhaust gas is arranged downstream from the SCR.
