An engine exhaust gas treatment system and method. The engine exhaust gas treatment system comprises an engine exhaust gas dust removal system and an engine exhaust gas ozone purification system. The engine exhaust gas dust removal system comprises an exhaust gas electric field device (1021) and an exhaust gas cooling device. The exhaust gas electric field device comprises an exhaust gas electric field device inlet, an exhaust gas electric field device outlet, an exhaust gas dust removal electric field cathode (10212), and an exhaust gas dust removal electric field anode (10211). The exhaust gas dust removal electric field cathode (10212) and the exhaust gas dust removal electric field anode (10211) are used for generating an exhaust gas ionization dust removal electric field. The exhaust gas cooling device is used for cooling exhaust gas in front of the exhaust gas electric field device inlet. The exhaust gas cooling device comprises a heat exchange unit (3071) used for performing heat exchange with the exhaust gas of an engine, so as to heat a liquid heat exchange medium in the heat exchange unit (3071) into becoming a gaseous heat exchange medium. The engine exhaust gas treatment system can effectively remove particulate matter from the exhaust gas of the engine, and has a better purification treatment effect on the exhaust gas of the engine. |
