[0082] Such as figure 1 As shown, the embodiments of the present invention provide a method for ultra-clean electric dust removal, specifically comprising the following steps:

[0083] Step S101: Applying high pressure to the gas to be dedusted for ionization, so that the dust is negatively charged.

[0084] Dust-containing gas is electrically separated when it passes through a high-voltage electrostatic field, and the dust is combined with negative ions to be negatively charged.

[0085] Step S102: Using the electrostatic dust removal method, under the action of the dust removal electric field formed by the cathode queue and the anode queue, the negatively charged dust is moved to the dust collection area, and the gas to be dust removed is subjected to dust removal treatment.

[0086] Electrostatic dust removal is a kind of gas dust removal method. The dust-containing gas is electrically separated when it passes through a high-voltage electrostatic field. After the dust part...

Abstract

The invention discloses a method and device for ultra-clean electric dust removal. The device comprises: a device body provided with a dust removal chamber, a gas inlet, a gas outlet, a high-voltage power supply device, an ash hopper, a plurality of cathode queues and anodes arranged in the dust removal chamber Queues, and dust cleaning devices; wherein, the cathode queues and the anode queues appear in pairs, and are arranged at least one-dimensionally apart from each other to form a dust removal electric field, and the dust removal electric field includes an electric field component facing away from the ash hopper. The invention uses a high-voltage power supply device to ionize the gas flowing through the gas inlet and into the dust removal chamber, so that the dust is negatively charged. Under the action of the dust removal electric field, the charged dust moves towards the ash hopper and falls into the ash hopper for dust removal. The final gas is discharged through the gas outlet; and the ash hopper and the anode queue with dust attached are cleaned by the dust cleaning device; the separation and capture of the charged dust are divided into two spaces to complete, avoiding the problem of secondary dust, The problem of difficult ash removal is solved by adding a dust removal device.

Description

technical field [0001] The invention relates to the field of environmental protection and industrial flue gas dust removal, in particular to an ultra-clean electric dust removal method and device. Background technique [0002] Industrial production will produce dust-laden gas, and the dust-laden gas will be discharged to the atmosphere after a large amount of dust is removed by dust removal facilities. [0003] Fine dust removal facilities mainly include bag filter and electrostatic precipitator. Electrostatic precipitator is widely used because of its small resistance, high dust removal efficiency and temperature resistance. [0004] The cost of electrostatic precipitator is high, and the dust containing high specific resistance (>10 10 ~10 13 Ω.cm) gas, the dust removal efficiency is reduced. In addition, the dust removal of the dust collector by vibration will cause the problem of secondary dust, which limits the further improvement of the application range and effic...
