Clean exhaust system and method for diesel engines of marine vessels

摘要

An emission control system (ECS) and associated method for facilitating the emulsification and/or dispersion of hydrocarbon, diesel particulate matter (DPM) and other pollutants from the exhaust gas output from a diesel engine of a marine vessel, includes a pump, a control system that controls the pump, and a product container containing an environmentally approved dispersing product. The ECS injects dispersing product into the engine's water cooling and exhaust system, for example, into the cooling water downstream of the engine and upstream of the spray ring or mixing elbow of the exhaust system. The environmentally approved dispersing product is drawn from the product container via the pump and injected at a controlled rate into the raw cooling water, and the dispersing product/cooling water mixture admixes with the exhaust gas resulting in emulsification and/or dispersion of the hydrocarbon, DPM and other pollutants present in the exhaust gas.

主权项

1. An emission control system (ECS) for facilitating the at least one of emulsification and dispersion of hydrocarbon, diesel particulate matter (DPM) and other pollutants from the exhaust gas output from a engine of a marine vessel, the engine including a water cooling and wet exhaust system, comprising:
an outlet pipe carrying raw cooling water from the engine water cooling to the wet exhaust system; a dosing pump; a product container containing an environmentally approved dispersing product; and a supply tube coupling the pump, dispersing product, and at least one of the water cooling system and the wet exhaust system; and wherein the environmentally approved dispersing product is injected at a controlled rate into the at least one of the water cooling system and the wet exhaust system.
