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

Embodiment 1

[0040] Embodiment 1: a kind of wet electrostatic precipitator, such as figure 1 As shown, the casing 1 is included, and the inside of the casing 1 is provided with a plurality of integrated boards 11 arranged in a vertical array, and a channel space 12 for gas circulation is provided between every two integrated boards 11, and in each channel A plurality of nozzle devices 13 extending along the length direction of the integrated board 11 are arrayed directly above the space 12, and a water storage tank 14 for storing waste liquid is provided in the housing 1 below the integrated board 11. One of the water storage tanks 14 The side is provided with the water pipe 15 for waste liquid discharge.

[0041]The gas containing dust enters the wet electrostatic precipitator, and the wet electrostatic precipitator charges the dust through high-voltage corona discharge, and the charged dust adheres to the surface of the integrated board 11 to realize the separation of the dust in the gas...

Embodiment 2

[0047] Embodiment 2: a kind of wet electrostatic precipitator, the difference with embodiment 1 is, as image 3 with 4 As shown, in order to make the working tank 3 better collect the liquid and reduce the waste of liquid, at this time, both sides of the working tank 3 are fixed and inclined with deflectors 33, that is, a deflector 33 is obliquely fixedly arranged on the working tank. On the outer side wall of the groove 3, another deflector 33 is obliquely fixedly arranged on the outer side wall of the driving cylinder 41; There is a notch groove 341 for the liquid to pass through, and a connecting spring 35 is fixed on the bottom of the deflector 33. The end of the connecting spring 35 away from the deflector 33 is connected and fixed to the bottom of the swing plate 34, that is, the connecting spring 35 can realize Supporting effect on the swing plate 34; at the same time, a brush layer 331 is provided on the side of the swing plate 34 away from the deflector 33, and the b...

Embodiment 3

[0051] Embodiment 3: a kind of wet electrostatic precipitator, the difference with embodiment 2 is, as Figure 5 As shown, at this time, a plurality of support springs 21 connected and fixed to the bottom of the working tank 3 are arranged in an array on the support plate 2 .

[0052] Specific implementation method: when there is no liquid in the working tank 3, the supporting springs 21 are not fully compressed, which can realize the supporting effect on the working tank 3, when the liquid is stored in the working tank 3, and under the extrusion effect of the sealing piston 43 , can realize the compression of the supporting spring 21, and the process of compressing the supporting spring 21 realizes the downward movement of the working tank 3. In this process, it can realize the scouring effect on the dust adhered on the integrated board 11 near the lower part, further improving effect on dust removal.

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...
