An engine exhaust gas treatment system, comprising an exhaust gas dust removal system and an exhaust gas ozone purification system. The exhaust gas dust removal system comprises an exhaust gas electric field device (1021) and an oxygen supplement device (208); the exhaust gas electric field device (1021) 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 oxygen supplement device (208) is used for adding a gas including oxygen before the shown exhaust gas ionization dust removal electric field. The exhaust gas ozone purification system comprises a reaction field (202) for mixing an ozone stream with an exhaust gas stream. The exhaust gas electric field device (1021) and an exhaust gas ozone device are combined to support each other in terms of function, and there is no need to additionally provide an ozone removal mechanism, and thus, the greenhouse effect is reduced. The engine exhaust gas treatment system can effectively remove particles in engine exhaust gas, and has a better purification and treatment effect on the engine exhaust gas. |
