An engine exhaust treatment system, comprising an engine exhaust dust removal system and an engine exhaust ozone purification system. The engine exhaust dust removal system comprises an exhaust dust removal system inlet, an exhaust dust removal system outlet, and an exhaust electric field device (1021); the exhaust electric field device (1021) comprises an exhaust electric field device inlet (3085), an exhaust electric field device outlet (3088), an exhaust dust removal electric field cathode (3081), and an exhaust dust removal electric field anode (3082); the exhaust dust removal electric field cathode (3081) and the exhaust dust removal electric field anode (3082) are configured to generate an ionizing exhaust dust removal electric field; the exhaust electric field device (1021) further comprises an auxiliary electric field unit; the ionizing exhaust dust removal electric field comprises a flow channel (3086); and the auxiliary electric field unit is configured to generate an auxiliary electric field that is not perpendicular to the flow channel (3086). By providing the auxiliary electric field, the exhaust electric field device (1021) still has a high efficiency of dust collection ability under high temperature impact, and the dust removal efficiency is high. The engine exhaust treatment system can effectively treat engine emissions and make the engine emissions cleaner. |
