Description

Technical Field

[0001] The present invention belongs to the technical field related to wet electrostatic precipitator, and more specifically, particularly relates to a wet electrostatic precipitator with high-efficiency regulating effect. Background Art

[0002] Wet electrostatic precipitator is a new type of dust removal equipment used to deal with trace dust and microparticles. It is mainly used to remove dust, acid mist, water droplets, aerosols, odors, PM2.5 and other harmful substances in humid gases. It is an ideal equipment for controlling atmospheric dust pollution. Wet electrostatic precipitator is usually referred to as WESP. It has the same basic dust removal principle as dry electrostatic precipitator. It has to go through three stages: charging, collection and cleaning. There are two main structural forms of wet electrostatic precipitator. One is to use corrosion-resistant conductive materials (which can be non-metallic materials with excellent conductive properties or metal materials with corrosion resistance) as dust collecting electrodes. The other is to form a conductive water film by spraying water or overflowing water, and use non-conductive non-metallic materials as dust collecting electrodes. However, the wet electrostatic precipitator in the prior art has the following defects:

[0003] In the prior art, the ventilation volume in the wet electrostatic precipitator is usually fixed. When the ventilation volume is too large, it is easy to cause the cathode dust collecting plate to adsorb dust to a limited extent, resulting in poor gas dust removal effect; when the ventilation volume is too small, more dust is adsorbed on one part of the cathode dust collecting plates, and less dust is adsorbed on another part of the cathode dust collecting plates, but all cathode dust collecting plates need to be fully cleaned, resulting in waste of clean water and extended cleaning time. Therefore, the dust removal efficiency cannot be adjusted according to the ventilation volume, which affects the use effect of the wet electrostatic precipitator.

[0004] There is a Chinese patent with application number CN202110877888.7 that discloses a wet electrostatic precipitator for air pollution treatment and a dust removal method thereof, comprising a main frame, a top sealing cover is fixedly installed on the top of the main frame by screws, a bottom sealing cover is fixedly installed on the bottom of the main frame by screws, a support base is fixedly installed below the outside of the main frame, an air intake pipe is fixedly installed below the left side of the main frame, and an anode discharge device is fixedly installed on the front of the air intake pipe. The wet electrostatic precipitator for air pollution treatment and the dust removal method thereof, when injecting dust-containing gas into the air intake pipe, discharges the gas through the discharge rods evenly distributed inside the air intake pipe, increases the contact time between the dust-containing gas and the discharge device, thereby ensuring that the dust particles in the gas can carry positive charges, ensuring that the cathode plate can completely adsorb the dust particles, and improving the dust removal effect of the device. With respect to the above-mentioned related technologies, the inventors believe that the following technical defects exist: each time a certain amount of dust is adsorbed on the cathode dust collecting plate, it is necessary to stop the gas from entering, and then clean the dust on the cathode dust collecting plate, which reduces the dust treatment effect of the entire wet electrostatic precipitator.

[0005] In the prior art, the cathode dust collecting plate in a wet electrostatic precipitator is usually cleaned directly by spraying water, resulting in poor efficiency and quality of cleaning the cathode dust collecting plate, thereby prolonging the cleaning time or failing to clean properly, affecting the efficiency of the cathode dust collecting plate in subsequent dust removal treatment of the gas and affecting the use of the wet electrostatic precipitator.

[0051] Specific use of the present invention:

[0052] The control system controls the first stepper motor 13 to start, and the first stepper motor 13 starts to drive the plurality of blades 16 to rotate, and the plurality of blades 16 rotate to suck the gas outside the housing 12 into the housing 12 through the air inlet 14. Then, the gas in the housing 12 enters the air inlet cavity 20 through the through hole 21.

[0053] When the dust content in the gas is low, the control system controls one of the solenoid valves 22 to open and the other solenoid valve 22 to close, so that the gas in the air inlet chamber 20 enters the corresponding dust removal chamber 24 through one of the solenoid valves 22. At this time, the control system controls the high-voltage generator 28 in the corresponding dust removal chamber 24 to energize the anode plate 26, so that an electric field is formed in the area near the anode plate 26, so as to charge the dust in the gas. Then, the gas drives the dust into the gap between the cathode plates 27, and the dust in the gas can be adsorbed onto the surface of the cathode plates 27 through the cathode plates 27. Then, the gas after dust removal enters the recovery box 45 through the connection port 47. At this time, the recovery box 45 contains a solution, so that the gas is further dusted by the solution in the recovery box 45. The fully treated gas is discharged through the outlet pipe 15.

[0054] Secondly, the control system controls the second stepper motor 29 to start, and the second stepper motor 29 starts to drive the rotating shaft 32 to rotate, and the rotating shaft 32 rotates to drive the four anode plates 26 and the four groups of cathode plates 27 to move clockwise, and the cathode plates 27 move into the through-port 49 to squeeze and rotate the rubber plate 50, and the rotation of the rubber plate 50 rotates the torsion spring 51 to generate elastic force. Then, when the four anode plates 26 and the four groups of cathode plates 27 move into the corresponding dust removal chamber 24 or cleaning chamber 25, the rubber plate 50 is rotated and reset under the elastic force of the torsion spring 51, so that the rubber plate 50 is blocked on the corresponding through-port 49, and the gas in the dust removal chamber 24 is prevented from entering the cleaning chamber 25 through the through-port 49.

[0055] Then, the control system controls the second stepper motor 29 to stop, and at this time, a plurality of new cathode plates 27 enter the corresponding dust removal chamber 24 to continue to remove dust from the gas, thereby continuously removing dust from the gas. At the same time, a plurality of cathode plates 27 with dust adsorbed enter the cleaning chamber 25. In the process of the cathode plates 27 adsorbing dust entering the cleaning chamber 25, the cathode plates 27 move to cooperate with the first brush block 37 or the second brush block 38 to contact the inner side or outer side of the cathode plates 27, so that the inner side or outer side of the cathode plates 27 can be initially cleaned; then, the rotating shaft 32 rotates to drive the turntable 33 to rotate, and the upper part of the turntable 33 is in an uneven wave-shaped structure, and the lower end of the push rod 35 is in sliding contact with the upper part of the turntable 33, so that the push rod 35 moves up and down, and the push rod 35 moves up and down to drive the moving plate 36 to move up and down, and the moving plate 36 moves up and down to drive the first brush blocks 37 and the second brush blocks 38 to move up and down, so as to improve the cleaning effect of the inner side or outer side of the cathode plates 27. At the same time, one end of the moving plate 36 is in oblique contact with one side of the guide block 40, and the moving plate 36 moves upward so that the moving plate 36 is guided by the guide block 40, so that the moving plate 36 can move horizontally during the upward movement. The movable plate 36 moves horizontally to make the slider 41 slide horizontally in the slide groove 42, and the movement of the slider 41 compresses the spring 43 to generate elastic force. Then, the movable plate 36 moves downward, and under the elastic force of the spring 43, one end of the movable plate 36 always contacts with the inclined surface of one side of the guide block 40, so that the movable plate 36 can move back and forth horizontally under the inclined guide of the guide block 40 during the process of the movable plate 36 moving up and down, and the movable plate 36 moves back and forth horizontally to drive the first brush blocks 37 and the second brush blocks 38 to move back and forth horizontally, so that the first brush blocks 37 and the second brush blocks 38 alternately contact the inner side or the outer side of the cathode plate 27, so that the dust adsorbed on the first brush blocks 37 or the second brush blocks 38 can be slapped off in time, and the service life of the first brush blocks 37 and the second brush blocks 38 can be extended, which is conducive to further improving the effect of cleaning the inner side or the outer side of the cathode plate 27.

[0056] Finally, the control system controls the reflux pump 48 to start, and the reflux pump 48 starts to drive the solution in the recovery box 45 into the water tank 30. The solution in the water tank 30 is sprayed into the cleaning chamber 25 through the water supply pipe 31, and the solution is used to clean the cathode plates 27 in the cleaning chamber 25. The cleaned solution falls to the upper side of the guide plate 34, so that the guide plate 34 tilts the solution and guides it to enter the recovery box 45 through the connecting port 47. The solution in the recovery box 45 is then filtered through the filter plate 46, so that the solution on the lower side of the recovery box 45 can be recycled.

[0057] When the dust content in the gas is high, the control system controls the first stepper motor 13 to improve the rotation efficiency, thereby increasing the rotation speed of the plurality of blades 16, so that a large amount of gas enters the housing 12 through the air inlet 14, and the gas in the housing 12 enters the air inlet chamber 20 through the through hole 21. At this time, the control system controls the two solenoid valves 22 to open, so that a large amount of gas in the air inlet chamber 20 enters the two dust removal chambers 24 for dust removal treatment, so as to adjust the effect of gas dust removal as needed. Among them, through the setting of the two dust removal chambers 24 and the two cleaning chambers 25, the efficiency of the dust removal treatment can be adjusted according to the degree of dust content in the gas, and the two groups of cathode plates 27 can be cleaned simultaneously in time, so as to maintain the dust removal efficiency of the four groups of cathode plates 27.

[0058] A wet electrostatic precipitator with a high-efficiency regulating effect of the present invention is provided with a dust removal component, and the rotating shaft 32 in the dust removal component is rotated to drive four anode plates 26 and four groups of cathode plates 27 to move clockwise, so that the four anode plates 26 and four groups of cathode plates 27 can be moved to the corresponding dust removal chamber 24 in turn, so that the four anode plates 26 and four groups of cathode plates 27 can adsorb dust in the gas, and the four anode plates 26 and four groups of cathode plates 27 can be moved to the cleaning chamber 25 in turn to clean the dust adsorbed on the cathode plates 27 through the cleaning component, so that the dust removal efficiency of the cathode plates 27 can be maintained, so that when cleaning the cathode plates 27 At the same time, it does not affect the normal operation of the gas dust removal treatment, and improves the efficiency of the dust treatment in the gas; then, through the cooperation of the rubber plate 50, the through port 49 and the torsion spring 51, the four groups of cathode plates 27 can be moved between the dust removal chamber 24 and the cleaning chamber 25 in turn, so as to facilitate continuous dust removal treatment of the gas and timely cleaning of the cathode plates 27, and can reduce the gas in the dust removal chamber 24 from entering the cleaning chamber 25; finally, through the setting of two dust removal chambers 24 and two cleaning chambers 25, the efficiency of the dust removal treatment can be adjusted according to the degree of dust content in the gas, and the two groups of cathode plates 27 can be cleaned simultaneously in time, so as to maintain the dust removal efficiency of the four groups of cathode plates 27.
