Abstract:
This exhaust gas treatment apparatus comprises: an EGR device for cleaning exhaust gas emitted from an engine main body of a marine diesel engine with scrubber water and recirculating the cleaned exhaust gas as part of combustion gas; a collection pipe for collecting condensed water generated from the combustion gas pressurized and compressed by a turbocharger and cooled by a cooler, and gas pressure from the cooled combustion gas; a condensed water chamber for receiving, through the collection pipe, and storing the condensed water, and accumulating the gas pressure; and a water supply pipe providing communication between the condensed water chamber and a supply destination device to which the condensed water is supplied. The condensed water is pumped from the condensed water chamber through the water supply pipe to the supply destination device using the gas pressure accumulated in the condensed water chamber.
