Because the high specific resistance dust charges are not easy to release after more dust is deposited on the inner wall of the metal sleeve, the dust with subsequent charges is discharged, namely back corona phenomenon is easy to generate, secondary dust emission is caused, and the dust collection effect is affected.
The invention provides an electrostatic dust collection device which comprises a purifying mechanism 8 provided with at least one purifying component, wherein the purifying component can charge dust and adsorb the dust on the inner wall of the purifying component, and a dielectric layer 3 capable of inhibiting back corona is wrapped on the outer wall of the purifying component.

Specifically, the dielectric layer 3 is wrapped on the metal sleeve 2, the dielectric layer 3 is made of a dielectric material with breakdown field strength of 0-40kV/cm, and in the embodiment, the dielectric layer 3 is made of polyimide.
Specifically, since the charged dust is deposited on the metal sleeve 2 as the dust collecting barrel, the charges are not easy to release, and as the dust layer is thickened, the charges are more difficult to release, on one hand, since the dust layer fails to release all the charges, the surface of the dust layer still has the same polarity of corona electrode, and the subsequent charged dust is repelled; on the other hand, because the charge of the dust layer is released slowly, a larger potential gradient is easy to form between the dust, and when the electric field intensity in the dust layer is larger than the critical value, local breakdown is generated between the pores of the dust layer, namely positive ions with the polarity opposite to that of a corona polar plate are generated, the generated ions move to the corona polar plate, negatively charged particles in the corona region are neutralized, and as a result, the current is increased, the voltage is reduced, and secondary dust flying is serious; the medium layer 3 is provided with a layer of charges with the same voltage polarity, positive charges are formed at the medium layer, the electric polarity of dust charge in a main migration area of corona discharge is positive charges, and according to the principle of repulsion of like charges, the positively charged dust is repelled from the surface of the positively charged medium, so that the dust is not easy to accumulate on the surface of the medium to generate secondary dust, namely, back corona phenomenon is restrained, and the occurrence of the secondary dust phenomenon is reduced.
Further, when the voltage exceeds the breakdown voltage, the voltage difference between the two electrodes of the discharging part 1 and the metal sleeve 2 is basically zero, the circuit is regarded as conducting, the current is instantaneously increased, dust is not influenced by the electric field force, namely the purifying effect disappears, a certain amount of charges can be accumulated on the dielectric layer 3 due to the fact that electrons, ions and the like are respectively accumulated in the anode and cathode moving process driven by the external voltage, an internal electric field opposite to the external voltage is formed, the total field intensity at a discharging gap is reduced, the electric field generated by the charges accumulated on the insulating dielectric layer 3 can also serve as a part of the external electric field for next discharging, and the external breakdown voltage required by a gas medium is reduced, so that the discharging can be realized under the voltage smaller than that of the direct-current corona, namely the arranged dielectric layer 3, the discharging can be realized without needing larger voltage, and the problem of direct-current corona spark breakdown is avoided.
In one embodiment, as shown in fig. 2, the electrostatic dust collection device further includes a dust collection component, the dust collection component is embedded in the medium layer 3, the dust collection component includes a plurality of electrode plates arranged in parallel, any two adjacent electrode plates can form paired electrodes with opposite positive and negative polarities, so that dust absorbed by the purification component falls off, two adjacent electrode plates form paired electrodes with opposite positive and negative polarities, one electrode plate serves as a high-voltage electrode 4, one electrode plate adjacent to the high-voltage electrode serves as a grounding motor 5, namely, when the power is applied, a plurality of wire-shaped discharge channels are formed on the surface of the medium between the high-voltage electrode 4 and the grounding electrode 5, coplanar discharge is formed, plasma generated by the coplanar discharge directly acts on the dust, so that the dust in an adsorption state is broken down and converted into small dust, and then the dust absorbed by the purification component falls off, so that the dust absorbed by the purification component can be removed under the condition that the electrode plates of the purification component are not dismounted, and meanwhile, the dust collection component is embedded in the medium layer 3, so that the service life of the dust collection component can be effectively avoided due to oxidation or corrosion of the electrode plates of the dust collection component.
Specifically, as shown in fig. 2, the plurality of electrode plates each extend in the axial direction of the metal sleeve 2; the plurality of electrode plates can also extend along the circumferential direction of the metal sleeve 2, namely the plurality of electrode plates sequentially encircle the metal sleeve 2 in parallel along the axial direction of the metal sleeve 2;
