Wet-type electric precipitator and application method thereof

Abstract

The invention provides a wet-type electric precipitator and an application method thereof. The wet-type electric precipitator comprises a shell, a plurality of cylindrical anode plates, a plurality of cathode wire rings, anode plate washing nozzles and cathode wire washing nozzles, wherein the cylindrical anode plates are concentrically distributed with different diameters; the cathode wire rings are arranged at intervals with the cylindrical anode plates; cathode wires comprises four-stage pointed end cathode wires, two-stage pointed end cathode wires and acupuncture pointed end cathode wires; a plurality of cathode wires are circularly distributed in the cathode wire rings through the following order of the four-stage pointed end cathode wires, the acupuncture pointed end cathode wires, the two-stage pointed end cathode wires and the acupuncture pointed end cathode wires; the anode plate washing nozzles are annularly arranged and located above the cylindrical anode plates; the cathode wire washing nozzles are annularly arranged and located above the anode plate washing nozzles. By virtue of the wet-type electric precipitator and the application method thereof, the effective dust collection area of a solar polar plate can be increased and the smoke blind area is effectively reduced; meanwhile, an electric field is uniformly partitioned, and thus the efficient and stable operation of the wet-type electric precipitator can be guaranteed.

Description

Technical field [0001] The invention relates to the field of dust removal, in particular to a wet electric dust collector and a method of use thereof. Background technique [0002] With the continuous improvement of environmental emission requirements in the domestic thermal power industry, the requirements for the efficiency of flue gas dust removal have further increased. Traditional dust removal methods such as mechanical dust removal, bag dust removal, electric dust removal, and electric bag dust removal can no longer meet the emission requirements. As an efficient dust removal technology, wet electric dust removal is widely promoted. Wet electrostatic precipitator is an extension of dry electrostatic precipitator technology. Compared with traditional electrostatic precipitator, this technology optimizes the method of dust removal. Wet electrostatic precipitator uses water film on the surface of the electrode plate to remove dust without secondary dust. Good applicability. ...

AI Technical Summary

Problems solved by technology

[0006] 2. In the traditional plate-line pole matching method, the blind area at the tower wall is relatively large, about 8% to 10%;

[0007] 3. Difficult to install and overhaul

[0008] The traditional built-in wet electrostatic precipitator can significantly increase the effective dust collection area by increasing the number of electric fields and increasing the height of the plate, but as the electric field height increases, the load-bearing of the absorption tower increases accordingly, and the foundation of the absorption The load-bearing design margin limits the height of the wet electrostatic precipitator; at the same time, the blind areas that appear in the traditional plate-line layout are generally treated by plugging, which in turn leads to an increase in the gas flow rate in the electric field area , which is higher than the design value, which affects the dust removal efficiency; furthermore, the traditional plate-line installation method is difficult to hoist, the support beam has poor uniformity of force, and it is difficult to realize partitioned power supply and difficult to maintain
