An exhaust gas dust removal system, comprising a dust removal system inlet, a dust removal system outlet and an electric field apparatus (1021), the electric field apparatus (1021) comprising an electric field apparatus inlet, an electric field apparatus 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) being used for producing an ionising dust removal electric field. A dust collection area of the dust removal electric field anode (10211) is larger than a discharge area of the dust removal electric field cathode (10212), so that an asymmetric electrode attraction force is produced between the electrodes, to reduce electric field couplings. |
