Description

The dust collection principle of wet electrostatic precipitators is the same as that of dry electrostatic precipitators. Both rely on high-voltage corona discharge to charge the dust. The charged dust reaches the dust collecting plate / tube under the action of the electric field force. Unlike dry electrostatic precipitators, wet electrostatic precipitators mainly deal with wet gases with high or even saturated water content. The moisture is also ionized to form a layer of water film on the surface of the anode plate. When the charged dust particles reach the collector, they will be captured by the water film and discharged with the water film.

[0039] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0040] First embodiment

[0041] Please refer to Figure 1-Figure 9 In the first embodiment of the present invention, the wet electrostatic precipitator comprises: a dust box 1, an air inlet box 2, an air outlet box 3 and an ash hopper 4. The air inlet box 2 and the air outlet box 3 are respectively fixedly installed on both sides of the dust box 1. An air flow distribution plate is installed in the air inlet box 2 to make the gas evenly dispersed and enter the dust box 1. An electrostatic dust particle catcher is installed in the air outlet box 3 to re-capture the uncaptured particles to ensure thorough dust removal. The ash hopper 4 is fixedly installed at the bottom of the dust box 1. A plurality of anode plates and a plurality of cathode plates are arranged inside, and a spray mechanism is also arranged above the anode plates and the cathode plates. Two movable sealing plates 5 are slidably installed on the top of the dust removal box 1. Two long strip openings are opened on the top of the dust removal box 1. The two movable sealing plates 5 cover the two long strip openings respectively. A plurality of guide slide bars 6 are penetrated and slidably installed on the movable sealing plates 5. The bottom ends of the plurality of guide slide bars 6 extend into the dust removal box 1 through the long strip openings, and the same rope rod 7 is fixedly installed. A plurality of cleaning ropes are installed between the two rope rods 7. 8, and multiple cleaning ropes 8 are located between the corresponding anode plate and cathode plate. In this embodiment, the two ends of the cleaning rope 8 are respectively fixed on the two rope rods 7, and the debris on the anode plate that cannot be washed away is scraped off by the cleaning rope 8. Under normal circumstances, the cleaning rope 8 and the rope rod 7 are both located below the anode plate. The tops of the multiple guide slide bars 6 are fixedly installed with the same top plate 9, and the bottom of the top plate 9 is fixedly installed with two counterweights 10. The top of the movable sealing plate 5 is fixedly installed with a vertical pile 11 and a motor 14. The top of the vertical pile 11 is fixedly installed with a fixed pulley 12. A winding wheel 15 is fixedly sleeved on the output end of the motor 14, and a traction belt 13 is wound around the rotating wheel of the fixed pulley 12. One end of the traction belt 13 is fixedly connected to the top plate 9, and the other end is fixedly connected to the winding wheel 15. The winding wheel 15 is driven by the motor 14 to rotate forward to reel in the traction belt 13. The traction belt 13 pulls the top plate 9 to move upward, and the top plate 9 drives the rope rod 7 to rise through the guide slide bar 6, and finally the rope rod 7 can be lifted to a position such as Figure 4The height position shown, at this time, multiple cleaning ropes 8 are located between the corresponding cathode plate and the anode plate, and two hydraulic cylinders 16 are fixedly installed on the top of the dust removal box 1, and the output ends of the two hydraulic cylinders 16 are fixedly connected to the two movable sealing plates 5 respectively. Specifically, the top of the movable sealing plate 5 is fixedly installed with a connecting plate, and the output ends of the hydraulic cylinders 16 are fixedly connected to the connecting plate. When the output ends of the two hydraulic cylinders 16 are started to retract, the two hydraulic cylinders 16 pull the corresponding movable sealing plate 5 to move backward respectively, and the movable sealing plate 5 will drive the guide slide bar 6 to move, so that the two rope rods 7 and then the multiple cleaning ropes 8 move backward, so that the cleaning rope 8 can contact the anode plate, and then start the operation of the motor 14 to drive the winding wheel 15 to rotate in the opposite direction to release the traction belt 13. Under the action of gravity, the top plate 9, the counterweight block 10, the guide slide bar 6, etc. will all move downward, so that the two rope rods 7 move downward, and the two rope rods 7 drive the multiple cleaning ropes 8 to move, so that the anode plate can be scanned and cleaned from top to bottom to scrape off the stubborn debris.

[0042] In this embodiment, in order to improve the stability of the two rope rods 7, a plurality of reinforcing struts are fixedly installed between the two rope rods 7.

[0043] In this embodiment:

[0044] When in use, the humid flue gas first enters the air inlet box 2, and is evenly distributed under the action of the air flow distribution plate before entering the dust removal box 1. After the cathode plate and the anode plate are energized, a strong electric field is formed between the corresponding cathode plate and the anode plate. The cathode plate (discharge electrode) generates corona discharge through high-voltage direct current, ionizing the surrounding gas to form a large number of free electrons and positive ions. Then, the free electrons and positive ions collide with the dust particles and charge them. The charged dust particles move toward the anode plate (collector) under the action of the electric field force, and the dust in the flue gas entering the dust collection unit is discharged. The moisture is also ionized, and a water film is formed on the surface of the anode plate. When the charged dust particles reach the collector, they will be captured by the water film and discharged with the water film, falling into the ash hopper 4, so that the flue gas is purified. The purified flue gas enters the air outlet box 3. Some electrostatic smoke particles that may not be captured in the flue gas will be captured again when passing through the electrostatic dust particle collector, and finally discharged from the outlet of the air outlet box 3. The spray mechanism can be opened regularly to wash the anode plate to wash away some debris that is adhered to the anode plate and cannot be washed away by the water film.

[0045] During the use of the wet electrostatic precipitator, some debris with strong adhesion sometimes accumulates on the anode plate, which cannot be removed by water film flow and flushing, and easily leads to spark discharge, short circuit between the plates and other problems. In this case, the two motors 14 are started to run, driving the two winding wheels 15 to rotate forward, and the two traction belts 13 are wound up. The traction belts 13 will lift the top plate 9, so that the two rope rods 7 and multiple cleaning ropes 8 gradually rise. Finally, as the motor 14 continues to travel far, the multiple cleaning ropes 8 will be lifted to the top position of the anode plate, and then the output ends of the two hydraulic cylinders 16 are started to retract, driving the two movable sealing plates 5 to move backward for a distance, and the movable sealing plates 5 drive the guide slide rods 6, rope rods 7 and other parts The cleaning rope 8 is moved so that the cleaning rope 8 gradually approaches the anode plate, and finally the cleaning rope 8 will contact the anode plate, and then the motor 14 is started to drive the winding wheel 15 to rotate in the opposite direction, and the traction belt 13 is released. Under the action of gravity, the top plate 9, the counterweight block 10, the guide slide bar 6, the rope rod 7 and other components will automatically move downward, driving the cleaning rope 8 to move downward. During the downward movement of the cleaning rope 8, the firmly bonded debris can be scraped off to achieve the cleaning of the anode plate. After the cleaning rope 8 moves to the bottom of the anode plate, the output ends of the two hydraulic cylinders 16 are started to extend, driving the mobile sealing plate 5 to reset, and the mobile sealing plate 5 drives the top plate 9, the counterweight block 10, the guide slide bar 6 and the like to reset, and finally the spray mechanism is started to rinse the anode plate again.

[0046] Compared with the related art, the wet electrostatic precipitator provided by the present invention has the following beneficial effects:

[0047] By moving the sealing plate 5, the guide slide bar 6, the rope rod 7, the cleaning rope 8, the top plate 9, the counterweight 10, the traction belt 13, the motor 14, the winding wheel 15, the hydraulic cylinder 16 and other components, when in use, starting the motor 14 can reel in the traction belt 13, and can lift the rope rod 7 and the cleaning rope 8, and then starting the hydraulic cylinder 16 to make the cleaning rope 8 contact with the anode plate, and then releasing the traction belt 13, so that the cleaning rope 8 can scan and clean the anode plate from top to bottom, so that the sundries that are firmly bonded to the anode plate are automatically scraped off, avoiding spark discharge or inter-stage short circuit between the anode plate and the cathode plate, which is beneficial to the long-term and reliable operation of the wet electrostatic precipitator. The entire cleaning process does not require personnel to enter the interior of the equipment, saving manpower.

[0048] Second embodiment:

[0049] Based on the wet electrostatic precipitator provided in the first embodiment of the present application, the second embodiment of the present application proposes another wet electrostatic precipitator. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0050] The second embodiment of the present invention is further described below in conjunction with the accompanying drawings and implementation modes.

[0051] Please refer to Figure 10-13 In the wet electrostatic precipitator proposed in this embodiment, the cleaning rope 8 is no longer directly fixed on the two rope rods 7, but is installed between the two rope rods 7 in a quick-release manner. Specifically, both ends of the cleaning rope 8 are fixedly installed with mounting buckle blocks 22, and a plurality of tightening screws 17 are penetrated and threadedly installed on the two rope rods 7. The tightening screw 17 is rotatably sleeved with a fixed circular plate 18 near one end of the cleaning rope 8, and the fixed circular plate 18 is slidably connected to the rope rod 7. A plurality of limiting sleeves 24 are fixedly installed on the top of the rope rod 7, and a limiting slide bar 23 is fixedly installed on the top of the fixed circular plate 18. The limiting slide bar 23 penetrates the limiting sleeve 24 and is slidably connected to the inner wall of the limiting sleeve 24. The cooperation between the positioning sleeve 24 and the limiting slide bar 23 can prevent the fixed circular plate 18 from happening. A limiting block 21 is fixedly installed on the fixed circular plate 18. A buckle block limiting groove 2101, a buckle block entrance port 2102 and a rope port 2103 are provided in the limiting block 21. The buckle block entrance port 2102 and the rope port 2103 are both connected with the buckle block limiting groove 2101. The installation buckle block 22 is located in the buckle block limiting groove 2101. When installing the cleaning rope 8, first put the installation buckle block 22 at one end of the cleaning rope 8 into the buckle block entrance port 2102, and then put the cleaning rope 8 into the rope port 2103. Then, pull the cleaning rope 8 to make the installation buckle block 22 enter the buckle block limiting groove 2101.

[0052] In this embodiment, a compression spring 19 is sleeved on the tightening screw 17, one end of the compression spring 19 is fixedly connected to the fixed circular plate 18, and the other end is fixedly connected to the rope rod 7. When the compression spring 19 is tightened, it gives the fixed circular plate 18 a reverse resistance force. After the resistance force acts on the tightening screw 17, the external thread of the tightening screw 17 and the internal thread hole opened on the rope rod 7 will be tightly engaged, thereby effectively preventing the tightening screw 17 from having loose threads.

[0053] In this embodiment, in order to isolate and protect the compression spring 19, a corrugated sleeve 20 is also provided on the tightening screw 17. The compression spring 19 is located in the corrugated sleeve 20. One end of the corrugated sleeve 20 is fixedly connected to the fixed circular plate 18, and the other end is fixedly connected to the rope rod 7.

[0054] In this embodiment:

[0055] When the cleaning rope 8 needs to be replaced after being used for a long time, the tightening screw 17 is rotated counterclockwise, so that the distance between the two tightening screws 17 becomes smaller. The tightening screw 17 drives the corresponding fixed circular plate 18 and the limiting block 21 to move during the counterclockwise rotation, so that the distance between the corresponding two limiting blocks 21 becomes smaller. In this way, the cleaning rope 8 changes from the previous tightened state to the relaxed state, and then the relevant personnel can first push the installation buckle block 22 into the buckle block entry port 2102, and then take it out upwards. After the installation buckle block 22 at the other end of the cleaning rope 8 is taken out in the same way, the removal of the cleaning rope 8 is completed;

[0056] When installing a new cleaning rope 8, the installation buckle blocks 22 at both ends of the cleaning rope 8 are respectively placed into the two buckle block entrance ports 2102, and then the installation buckle blocks 22 are pushed into the buckle block limiting grooves 2101. With the restriction of the buckle block limiting grooves 2101, the two installation buckle blocks 22 cannot separate from the corresponding limiting blocks 21 by themselves, and then the two tightening screws 17 are rotated clockwise in sequence to increase the distance between the two tightening screws 17. This will make the cleaning rope 8 taut and straight, thereby completing the installation of the new cleaning rope 8.

[0057] In this embodiment, by setting installation buckle blocks 22 at both ends of the cleaning rope 8, combined with the settings of tightening screws 17, fixed circular plates 18, compression springs 19, limiting blocks 21 and other components, the installation buckle blocks 22 can be restricted after being placed in the buckle block limiting grooves 2101 on the limiting blocks 21, so that the cleaning rope 8 will not fall off. After the tightening screws 17 corresponding to the two ends of the cleaning rope 8 are rotated counterclockwise, the cleaning rope 8 can be loosened from being tight. Then, the two installation buckle blocks 22 are taken out from the corresponding limiting blocks 21 respectively, and the cleaning rope 8 is disassembled. Then a new cleaning rope 8 is installed. After the installation buckle blocks 22 at both ends of the cleaning rope 8 are placed in the corresponding buckle block limiting grooves 2101, the two tightening screws 17 are rotated clockwise in sequence to straighten and tighten the cleaning rope 8, and the installation of the new cleaning rope 8 is completed. The operation is simple and greatly facilitates the replacement of the cleaning rope 8.

[0058] Third embodiment:

[0059] Based on the wet electrostatic precipitator provided in the second embodiment of the present application, the third embodiment of the present application proposes another wet electrostatic precipitator. The third embodiment is only a preferred mode of the second embodiment, and the implementation of the third embodiment will not affect the independent implementation of the second embodiment.

[0060] The second embodiment of the present invention is further described below in conjunction with the accompanying drawings and implementation modes.

[0061] Please refer to Figure 14-18In the wet electrostatic precipitator proposed in this embodiment, a sound and light alarm 25 is also fixedly installed on the top of the dust removal box 1, a fixed box 26 located below the rope mouth 2103 is fixedly installed on the outer wall of the limiting block 21 away from the fixed circular plate 18, the same mounting circular plate 29 is slidably installed on the inner walls of both sides of the fixed box 26, and two slide bars are fixedly installed on the outer wall of the mounting circular plate 29, and limited slide rails are fixedly installed on the inner walls of both sides of the fixed box 26, and the ends of the two slide bars away from each other extend into the corresponding limited slide rails and are slidably connected with the inner walls of the corresponding limited slide rails, a first conductive block 30 is fixedly installed on the mounting circular plate 29, and a second conductive block 32 located in the fixed box 26 is fixedly installed on the limiting block 21, and a telescopic slide rod 27 is slidably installed on the outer wall of the fixed box 26 away from the limiting block 21, one end of the telescopic slide rod 27 extends into the fixed box 26 and is fixedly connected with the mounting circular plate 29, and the telescopic slide rod 27 is sleeved with a tension spring 31 located in the fixed box 26 One end of the tension spring 31 is fixedly connected to the mounting circular plate 29, and the other end is fixedly connected to the inner wall of the fixing box 26 on one side away from the limiting block 21. Under the action of the tension spring 31, the mounting circular plate 29 and the limiting block 21 maintain a certain distance under normal conditions, so that the first conductive block 30 and the second conductive block 32 are in a separated state, and the first conductive block 30 and the second conductive block 32 are respectively connected to external wires to form a "normally open point". After connecting multiple "normally open points" in parallel, they are then connected in series to the power supply circuit of the sound and light alarm 25. When any cleaning rope 8 breaks, it will sag under the action of gravity and press on the telescopic slide rod 27, so that the telescopic slide rod 27 moves into the fixing box 26, and the telescopic slide rod 27 will push the mounting circular plate 29 to move, so that the first conductive block 30 contacts the second conductive block 32, so that the "normally open point" is closed, and then the power supply circuit of the sound and light alarm 25 is connected, and an sound and light prompt is issued, so that relevant personnel can promptly know the information that the cleaning rope 8 breaks.

[0062] In this embodiment, in order for the telescopic slide rod 27 to reliably receive the pressure of the cleaning rope 8 , a contact arc rod 28 is fixedly mounted on one end of the telescopic slide rod 27 located outside the fixing box 26 .

[0063] In this embodiment:

[0064] Through the above arrangement, when any cleaning rope 8 breaks, the broken cleaning rope 8 will droop downward under the action of gravity, and will enter the contact arc rod 28, giving the contact arc rod 28 an oblique downward pressure. Under the action of the horizontal component of the pressure, the telescopic slide rod 27 will move into the fixed box 26, and the telescopic slide rod 27 will push the mounting circular plate 29 to move, so that the first conductive block 30 contacts the second conductive block 32, so that the "normally open point" is closed, and then the power supply circuit of the sound and light alarm 25 is connected, and an sound and light prompt is issued, so that relevant personnel can promptly obtain the information that the cleaning rope 8 has broken, so that the cleaning rope 8 can be inspected or replaced in time. In the above process, the tension spring 31 will be stretched to store elastic potential energy; when the broken cleaning rope 8 is removed, the tension of the tension spring 31 will reset the telescopic slide rod 27, and the corresponding first conductive block 30 and second conductive block 32 will also be separated.

[0065] In the present embodiment, through the arrangement of components such as the sound and light alarm 25, the fixed box 26, the telescopic slide rod 27, the mounting circular plate 29, the first conductive block 30, and the second conductive block 32, when the cleaning rope 8 breaks, the sound and light alarm 25 can be automatically triggered to emit a sound and light prompt, so that relevant personnel can promptly obtain information on the breaking of the cleaning rope 8, so that the broken cleaning rope 8 can be replaced in time, thereby further improving the convenience of using the wet electrostatic precipitator.
