Exhaust gas purification device for marine diesel engines using low quality fuel such as heavy oil containing sulfur component at high concentration

摘要

Provided is an exhaust gas purification equipment for a marine diesel engine allowing discharge of treated waste water of treated discharge water to the ocean even during sailing in and outside special areas, particularly in exhaust gas treatment of a marine diesel engine using low-quality fuel such as fuel oil containing high-concentration sulfur components. The exhaust gas purification equipment is characterized by providing a scrubber that hardly removes PM using a difference in diffusion speed between gas and particles to an exhaust pipe continued to an exhaust manifold of an engine.
