Wet electrostatic precipitator

Abstract

The invention discloses a wet electrostatic precipitator. The wet electrostatic precipitator comprises shell, a plurality of integrated plates which are vertically arranged in an array manner are arranged in the shell, a channel space for a gas to circulate is arranged between two adjacent integrated plates, a plurality of nozzle devices extending along the length direction of the integrated plates are arranged over the channel spaces in an array manner, a water storage tank for storing a waste liquid is arranged, below the integrated plates, in the shell, a plurality of support plates are arranged on the water storage tank in an array manner, the support plates are arranged in the channel spaces, a working groove for storing a liquid is fixedly arranged on every support plate, two sidewalls of every working groove are provided with a plurality of spraying holes in an array manner, the working grooves are arranged, close to the lower-middle parts of the integrated plates, in the channel spaces, magnetic cover plugs for sealing the spraying holes are hinged to the spraying holes, and every working groove is provided with a pressing device for extruding and spraying the liquid. The wet type electrostatic precipitator can improve the internal dust removal effect and reduce the waste of the liquid.

Description

technical field [0001] The invention relates to the field of dust removal equipment, in particular to a wet electric dust collector. Background technique [0002] Wet electrostatic precipitator is a new dust removal equipment used to deal with trace dust and fine particles. It is mainly used to remove dust, acid mist, water droplets, aerosol, odor, PM2.5 and other harmful substances in wet gas. It is an ideal equipment for controlling air dust pollution. [0003] Its working principle is to rely on high-voltage corona discharge to charge the dust, and the charged dust adheres to the integrated board under the action of the electric field force, and then through regular flushing, the dust is removed with the flow of flushing fluid . [0004] Since the integrated plate has a certain height, the flushing liquid is sprayed through the device of multiple nozzles located on the top of the integrated plate in the dust collector. The dust attached to the integrated board is taken...

AI Technical Summary

Problems solved by technology

[0004] Since the integrated plate has a certain height, the flushing liquid is sprayed through the device of multiple nozzles located on the top of the integrated plate in the dust collector. The dust attached to the integrated board is taken away together to realize the dust scouring work; during this process, the liquid just sprayed out by the nozzle has a certain ejection force, and the ejection force acts on the surface of the integrated board near the nozzle , can better realize the scouring effect on the dust adhering to the integrated board, but because the farther away from the nozzle, the spray force of the liquid on the integrated board is smaller, and the dust adhered to the integrated board at this time is only It can rely on the flow of liquid to achieve removal. At this time, it is easy to cause incomplete dust cleaning, and the frequency of liquid flushing needs to be increased, resulting in waste of liquid
