Abstract: An air dust removal system (101), comprising a dust removal system inlet, a dust removal system outlet, and an electric field device (1014). The electric field device (1014) comprises 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) being used for generating an ionizing dust removal electric field. The dust removal electric field anode (10141) comprises a first anode portion (101412) and a second anode portion (101411), the first anode portion (101412) being close to the electric field device inlet (1011), the second anode portion (101411) being close to the electric field device outlet, and at least one cathode support plate (10143) being provided between the first anode portion (101412) and the second anode portion (101411). The air dust removal system (101) is able to effectively remove particulate matters in the air.

An air dust removing method, comprising the follow steps: providing an electret element (205) in a position without dust in an electric field when an ionization dust removing electric field has a power-on driving voltage; when the ionization dust removing electric field has no power-on driving voltage, using the electret element (205) to absorb particulate matters in the air.

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
