Abstract: An air dust removal system (101) includes a dust removal system inlet, a dust removal system outlet, and an electric field device (1014). The electric field device (1014) has an electric field device inlet (1011), an electric field device outlet, a dust removal electric field cathode (10142), and a dust removal electric field anode (10141). The dust removal electric field cathode (10142) and the dust removal electric field anode (10141) generates an ionizing dust removal electric field. The dust removal electric field anode (10141) has a first anode portion (101412) and a second anode portion (101411). The first anode portion (101412) is close to the inlet of the electric field device (1014), and the second anode portion (101411) is close to the outlet of the electric field device (1014). At least one insulating mechanism (1015) is provided between the first anode portion (101412) and the second anode portion (101411).

Abstract: An engine exhaust gas ozone purification method, comprising: mixing a ozone stream and an exhaust stream to react, and removing nitric acid in a reaction product of the ozone stream and the exhaust stream mixture. A gas that has a nitric acid mist is caused to flow through a first electrode (301). When the gas that has the nitric acid mist flows through the first electrode (301), the first electrode (301) charges the nitric acid mist in the gas, and a second electrode (302) applies an attractive force to the charged nitric acid mist, so that the nitric acid mist is moved toward the second electrode (302) until the nitric acid mist adheres onto the second electrode (302). The present engine exhaust gas ozone purification method does not need to add a large amount of urea, and the purification effect is good.

Abstract: A system for removing dust in air (101) comprises a dust removal system inlet (1011), a dust removal system outlet, and an electric field device (1014). The electric field device (1014) comprises an electric field device inlet (3085), an electric field device outlet (3088), a dust removal electric field cathode (3081), and a dust removal electric field anode (3082). The dust removal electric field cathode (3081) and the dust removal electric field anode (3082) are configured to generate an ionizing dust removal electric field. The electric field device (1014) further comprises an auxiliary electric field unit. The ionizing dust removal electric field comprises a flow channel (3086). The auxiliary electric field unit is configured to generate an auxiliary electric field that is not perpendicular to the flow channel (3086). The system for removing dust in air (101) can effectively remove particles in the air.

Abstract: A method for reducing dust removal electric field couplings, comprising the following steps: selecting a dust removal electric field anode and/or dust removal electric field cathode parameter to reduce a number of electric field couplings. A dust removal electric field anode and/or dust removal electric field cathode size is selected so that the number of electric field couplings is less than or equal to 3. The number of electric field couplings is reduced, electric field energy consumption is low, electric field coupling consumption for an aerosol, water mist, oil mist and loose smooth particulate matter is reduced, and electric field energy is saved
