Abstract: A method for reducing dust removal electric field couplings includes the following steps: selecting a ratio between a dust collection area of a dust removal electric field anode and a discharge area of a dust removal electric field cathode to be 1.667:1-1680:1. 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.

Abstract: An exhaust dust removal system includes an electric field device (1021) and a cooling device. The electric field device (1021) has an electric field device inlet, an electric field device outlet, a dust removal electric field cathode (10212), and a dust removal electric field anode (10211). The dust removal electric field cathode (10212) and the dust removal electric field anode (10211) are used to generate an ionizing dust removal electric field. The cooling device is used to reduce the exhaust temperature before the electric field device inlet. The exhaust dust removal system may help reduce greenhouse gas emissions, and may also help reduce emissions of harmful gases and pollutants, which thereby makes the gas emissions more environmentally friendly.
