ENGINE EXHAUST GAS TREATMENT SYSTEM AND METHOD

WIPO Patent Application WO/2020/083211

A1

An engine exhaust gas treatment system and method, comprising an engine exhaust gas dust removal system and an engine exhaust gas ozone purification system, the engine exhaust gas ozone purification system comprising a denitration apparatus (203), used for removing the nitric acid in the mixed reaction product of the ozone stream and the exhaust gas stream. The denitration apparatus comprises an electro-coagulation apparatus (2031), the electro-coagulation apparatus (2031) comprising a first electrode (301) and a second electrode (302), the first electrode (301) being electrically connected to a negative electrode of a power source, and the second electrode (302) being electrically connected to a positive electrode of the power source, the voltage of the power source being less than the corona inception voltage. The electro-coagulation apparatus has strong ability and high efficiency for collecting water mist containing nitric acid. The present engine exhaust gas treatment system can effectively treat engine emissions, such that the emissions of the engine are cleaner.
