Air dust removal system and method

An electric field device, including a dedusting electric field cathode and a dedusting electric field anode, the dedusting electric field anode and the dedusting electric field cathode are for generating an ionization dedusting electric field, the electric field device detects an electric field current when the dust is accumulated on the ionization dedusting electric field, when a detected electric field current has increased to a given value, the electric field device increases an electric field voltage, thus performing a dust cleaning treatment.

An air dedusting method, including the following step:

• a) enabling a dust-containing gas to pass through an ionization dedusting electric field generated by a dedusting electric field anode and a dedusting electric field cathode;
• b) performing a dust cleaning treatment when dust is accumulated in the electric field;
• wherein the dust cleaning treatment is performed when a detected electric field current has increased to a given value.
