APPARATUS FOR REMOVING SULFUR OXIDE IN SHIP EXHAUST GAS USING BALLAST PUMP

摘要

The present invention relates to a seawater supply apparatus for removing sulfur oxide in ship exhaust gas, and an object thereof is to provide a seawater supply apparatus for removing sulfur oxide in ship exhaust gas that is capable of supplying seawater for removing sulfur oxide to a seawater scrubber, which is connected to a main engine and a generator engine, without widening a space of a ship system. The seawater supply apparatus of the present invention for removing sulfur oxide in ship exhaust gas by using seawater includes a first scrubber (10) into which exhaust gas (G1) discharged from the main engine of the ship flows to be purified by seawater for cleaning; a second scrubber (20) that cleans exhaust gas (G2) discharged from the generator engine of the ship by using seawater for cleaning; a ballast pump (40) that supplies seawater for cleaning to the first scrubber (10) through a seawater supply line (31) and supplies seawater to a ballast tank (B) of the ship; an auxiliary seawater pump (50) that supplies seawater for cleaning to the second scrubber (20); a scrubber tank (60) where contaminated seawater discharged from the first and second scrubbers (10 and 20) is collected; a circulating treatment unit (70) that treats, circulates, and purifies the contaminated seawater in the scrubber tank (60); and a coolant pump (80) that supplies seawater for dilution to the contaminated seawater discharged from the first and second scrubbers (10 and 20), discharges the used seawater out of the ship through a seawater discharge line (32), and supplies an engine coolant (C) for the ship.;COPYRIGHT KIPO 2014
