TREATMENT UNIT OF EXHAUST GAS FROM SHIP

摘要

PURPOSE: An exhaust gas treatment apparatus for a ship is provided to improve the space use efficiency because an SCR(Selective Catalytic Reduction) reactor is an exhaust gas discharge pipe of an engine due to the reduced size. CONSTITUTION: An exhaust gas treatment apparatus for a ship comprises a plasma reactor(40), an energy recovery device(20), a urea storage facility(30), and an SCR reactor(50). The plasma reactor eliminates NOx, SOx and soot. The energy recovery device generates electric energy using waste heat of exhaust gas produced from a diesel engine(10) for a vessel. The energy recovery device supplies electrical energy to the plasma reactor. The urea storage facility supplies ammonia or urea to the plasma reactor to remove SOx and NOx. The SCR reactor eliminates the NOx which is not removed by the plasma reactor.
