Title:
ENGINE EXHAUST GAS DUST REMOVAL SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2020/083157
Kind Code:
A1
Abstract:
An engine exhaust gas dust removal system, comprising an exhaust gas dust removal system inlet, an exhaust gas dust removal system outlet, and an exhaust gas electric field device (1021). The exhaust gas electric field device (1021) comprises an exhaust gas electric field device inlet (3085), an exhaust gas electric field device outlet (3088), an exhaust gas dust removal electric field cathode (3081, 10212), and an exhaust gas dust removal electric field anode (3082, 10211). The exhaust gas dust removal electric field cathode (3081, 10212) and the exhaust gas dust removal electric field anode (3082, 10211) are used for generating an exhaust gas ionization dust removal electric field. The exhaust gas dust removal electric field anode (10211) comprises a first anode portion and a second anode portion. The first anode portion is close to the exhaust gas electric field device inlet, and the second anode portion is close to the exhaust gas electric field device outlet. At least one exhaust gas insulating mechanism (1022) is arranged between the first anode portion and the second anode portion to realize insulation between the exhaust gas dust removal electric field cathode (10212) and the exhaust gas dust removal electric field anode (10211). The engine exhaust gas dust removal system has a good dust removal effect, and can effectively remove particulate matter from exhaust gas of an engine.
