Title:
ENGINE EXHAUST GAS TREATMENT SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2020/083217
Kind Code:
A1
Abstract:
An engine exhaust gas treatment system, comprising 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 dust-removal system inlet, an exhaust gas dust-removal system outlet, an exhaust gas electric field device (1021), and a water removal device (207); 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 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 water removal device (207) is an electrocoagulation device for removing liquid water before the exhaust gas electric field device inlet. By providing the water removal device (207), the uneven discharge of the exhaust gas ionization dust-removal electric field and the breakdowns of the exhaust gas dust-removal electric field cathode and the exhaust gas dust-removal electric field anode can be reduced, thereby improving ionization dust-removal efficiency. The engine exhaust gas treatment system can effectively treat engine emissions, so that the engine emissions are cleaner.
