Description

Technical Field

[0001] The invention belongs to the field of environmental protection equipment technology, and more specifically relates to a corona module and a wet electrostatic precipitator thereof. Background Art

[0002] The working principle of wet electrostatic precipitator is similar to that of dry electrostatic precipitator, both of which include three stages: charging, collection and cleaning. The specific process is: the metal discharge wire ionizes the surrounding gas under the action of DC high voltage, so that the surface of dust or droplet particles is charged, and the charged particles move toward the dust collecting electrode under the action of the electric field force and deposit on the dust collecting electrode. After that, water flows down from the top of the dust collecting plate, flushing the dust captured on the plate into the ash hopper and discharged with water.

[0003] The patent document with announcement number CN220634786U records a new type of multi-stage wet electrostatic precipitator, which includes an air outlet, a main shell, an air inlet, a primary water bath, a sewage pipe, a secondary water bath, a dust removal electric field, and a water level control mechanism. The air outlet is arranged above the main shell, and a secondary water bath and a primary water bath are arranged at the bottom of the main shell, and a dust removal electric field is arranged inside the main shell. The lower ends of the secondary water bath and the primary water bath are both provided with sewage pipes, and a water level control mechanism is arranged on the side of the secondary water bath, and an air inlet is installed above the primary water bath. The multi-stage wet electrostatic precipitator adopts multi-stage water bath dust removal and cooperates with the upper electric field for dust removal. It has better dust removal effect and more stable operation. In addition, the multi-stage wet electrostatic precipitator has a compact structure and occupies a small area.

[0004] The above-mentioned equipment has certain shortcomings when in use. The traditional wet electrostatic precipitator adopts a dust collecting electrode with a plate-like structure for dust removal operation. The traditional wet electrostatic precipitator uses the water film, spray structure or vibration generated by the operation of the equipment to clean its dust collecting electrode structure. There are multiple groups of dust collecting electrode structures inside the wet electrostatic precipitator, which need to be cleaned regularly to ensure the use effect of the dust collecting electrode. The dust collecting electrode with a plate-like structure is not conducive to cleaning operation, and conventional cleaning structures are prone to residue, which reduces the self-cleaning effect of the wet electrostatic precipitator. Summary of the invention

[0005] The object of the present invention is to provide a corona module and a wet electrostatic precipitator thereof, which can solve the existing problems.

[0006] The problem to be solved by the present invention is:

[0007] Traditional wet electrostatic precipitators use a plate-like structure dust collecting electrode for dust removal operations. Traditional wet electrostatic precipitators use the water film, spray structure or vibration generated by the operation of the equipment to clean its dust collecting electrode structure. There are multiple groups of dust collecting electrode structures inside the wet electrostatic precipitator, which need to be cleaned regularly to ensure the use effect of the dust collecting electrode. The plate-like structure of the dust collecting electrode is not conducive to cleaning operations, and conventional cleaning structures are prone to residues, which reduces the self-cleaning effect of the wet electrostatic precipitator.

[0008] The purpose of the present invention can be achieved through the following technical solutions:

The exhaust gas is introduced into the inside of the box shell by means of the air inlet nozzle. When the anode tube and the cathode wire are energized, an electric field is formed between the anode tube and the cathode wire. Under the action of the electric field, the surrounding gas is ionized to generate a large number of electrons and positive and negative ions. When the dust-containing flue gas and water mist enter the electric field, the dust particles are rapidly discharged under the action of the electrons and ions. Charged, the charged dust particles will quickly tend to the electrode with opposite polarity under the action of electric field force, and the water mist in the flue gas will also be charged and collected together with the dust particles, so that the water mist and dust particles adhere to the inner wall of the anode tube, and the water mist deposited on the inner wall of the anode tube will form a layer of water film, which helps to keep the anode plate clean. During use, some dust will flow downward along with the water film on the inner wall of the anode tube to complete its self-cleaning operation. During maintenance operation, the spray rack can be used to spray and flush the anode tube to keep the anode tube in good condition.

[0012] As a further technical solution of the present invention, the filter includes a limit frame and an adjustment frame. The adjustment frame is movably installed on the inner side of the limit frame, and the limit frame is fixedly installed on the inner side of the liquid collecting bucket.

[0013] As a further technical solution of the present invention, two groups of vacuum cleaners used in conjunction with the filter pad are fixedly installed on the outer surface of the upper end of the limit frame, and drivers for use with the adjustment frame are provided in the middle of both sides of the limit frame. By using the vacuum cleaner setting, the filter pad can be vacuumed and cleaned when the filter pad passes through the lower part of the vacuum cleaner, thereby removing the dust accumulated in the filter pad and allowing the filter pad to be used continuously.

The rotating rod and the motor are driven by gears. The driving wheel is fixedly installed on the outer surface of one end of the rotating rod.

The combination frame and the moving frame, as well as the moving frame and the moving slider, are driven by linear motors. The moving frame is driven by the linear motor so that the moving frame can translate on the inner side of the combination frame. The moving slider is driven by another set of linear motors so that the moving slider can translate on the inner side of the moving frame, thereby completing the two-way position adjustment of the cleaning ring, so that the cleaning ring can be moved to the bottom of any anode tube.

[0016] As a further technical solution of the present invention, a cylinder body is fixedly installed in the middle of the lower end of the movable slider, and the interior of the cylinder body is a double-cavity structure. Two sets of lifting push rods are movably sleeved on one end of the cylinder body. The cylinder body is used to drive the lifting push rods, so that the lifting push rods can drive the cleaning ring to move up and down, thereby completing the cleaning operation of the inner wall of the anode tube.

[0017] As a further technical solution of the present invention, a cleaning ring is fixedly installed on the upper end of the two groups of lifting push rods, and the two groups of lifting push rods are symmetrically arranged. The cleaning ring is an overall circular ring structure, and the outer surface of the cleaning ring is provided with an annular brush. Because a cathode wire is provided in the middle of the anode tube, the arrangement of the two groups of lifting push rods can avoid the cathode wire and allow the cathode wire to pass through the cleaning ring to complete the cleaning operation of the anode tube.

[0018] As a further technical solution of the present invention, a cover plate is provided on the outer surface of one side of the box shell for use with the combination frame. The box shell and the combination frame are spliced ​​and fixed by means of a card slot. After opening the cover plate, the card slot structure can be used to complete the splicing and fixation between the box shell and the combination frame. After the maintenance of the wet electrostatic precipitator is completed, the combination frame can be taken out so that the wet electrostatic precipitator can be used normally.

[0019] Beneficial effects of the present invention:

[0020] 1. By providing an anode tube and a fixed base, when the corona module and its wet electrostatic precipitator are used, the use effect of the cleaning ring can be improved;

[0021] Compared with the traditional non-columnar dust collecting pole, the anode tube with a columnar structure design allows the cleaning ring to cooperate with the annular brush to fit the inner wall of the anode tube when it moves up and down, so as to better complete the cleaning operation. At the same time, it can cooperate with the circular through hole of the truncated cone structure, so that the cleaning ring can avoid dislocation when it moves up, so that the cleaning ring can pass through the circular through hole and be inserted into the inner wall of the anode tube, thereby improving the stability of the cleaning ring when it is used.

[0022] 2. By providing a cleaning ring and a moving frame, when the corona module and its wet electrostatic precipitator are used, they have a lifting inner wall cleaning structure, which can perform a self-cleaning operation on the dust collecting structure, thereby improving the use effect of the wet electrostatic precipitator;

[0023] During operation, the exhaust gas is introduced into the interior of the box shell by using the air inlet nozzle. When the anode tube and the cathode wire are energized, an electric field is formed between the anode tube and the cathode wire. The anode tube is equivalent to a dust collecting electrode. Under the action of the electric field, the surrounding gas is ionized to generate a large number of electrons and positive and negative ions. When the dust-containing flue gas and water mist enter the electric field, the dust particles are quickly charged under the action of electrons and ions. Under the action of the electric field force, the charged dust particles quickly tend to the electrode with the opposite polarity. At the same time, the water mist in the flue gas will also be charged and collected together with the dust particles, so that the water mist and dust particles adhere to the inner wall of the anode tube;

[0024] After a period of use, dust will accumulate on the inner wall of the anode tube. At this time, the wet electrostatic precipitator is closed, and after the cover is opened, the card slot structure can be used to complete the splicing and fixation between the box shell and the combined frame, and the combined frame is installed under the anode tube. The moving frame is driven by a linear motor so that the moving frame can be translated on the inner side of the combined frame, and another set of linear motors is used to drive the moving slider so that the moving slider can be translated on the inner side of the moving frame, thereby completing the two-way position adjustment of the cleaning ring, so that the cleaning ring can be moved to the bottom of any anode tube. The controller is programmed according to the number and position of the anode tubes to move the cleaning ring to the bottom of all the anode tubes in sequence. Because a cathode wire is arranged in the middle of the anode tube, the two sets of lifting push rods can avoid the cathode wire and allow the cathode wire to pass through the cleaning ring to complete the cleaning operation of the anode tube. The cylinder body is used to drive the lifting push rod, so that the lifting push rod can drive the cleaning ring to move up and down, thereby completing the cleaning operation of the inner wall of the anode tube. The cleaning operation can be used in conjunction with the spray rack to flush the accumulated dust through the water body to improve the cleaning effect of the anode tube.

[0025] 3. By setting a filter, when the corona module and its wet electrostatic precipitator are used, the use of the cleaning ring and the spray rack is optimized, so that it has a dust-containing liquid filtering structure, which can remove dust in the liquid and reduce the cost of equipment use;

[0026] During use, after the anode tube and the cathode wire are energized, the electrostatic force can be used to absorb liquid and dust when the gas passes through the anode tube, so that the water mist and dust particles are attached to the inner wall of the anode tube, and the water mist deposited on the inner wall of the anode tube will form a layer of water film, which helps to keep the anode plate clean. During use, some dust will flow downward along with the water film on the inner wall of the anode tube, and the flowing water is mixed with a large amount of dust. The filter pad can be used to filter the dust-containing accumulated liquid discharged by the wet electrostatic precipitator, and the setting of the adjustment frame can arbitrarily move the two groups of filter pads on the inner side of the limit frame, so as to adjust the use position of the filter pad, so that the two groups of filter pads are used alternately, so that the filter can stably filter the dust-containing accumulated liquid discharged into the liquid collecting hopper, and the vacuum cleaner setting can be used to vacuum and clean the filter pad when the filter pad passes through the lower part of the vacuum cleaner, so as to remove the dust in the filter pad, so that the filter pad can be used continuously, and at the same time, the sewage discharged when the cleaning ring and the spray rack are used can be filtered.

[0040] like Figure 3As shown, a spray rack 11 is arranged inside the box shell 8 above the anode tube 4, an exhaust nozzle 10 is fixedly installed on the upper end of the box shell 8, and an air inlet nozzle 9 is fixedly installed at the lower position of one side of the box shell 8. The air inlet nozzle 9 is used to introduce the exhaust gas into the inside of the box shell 8. When the anode tube 4 and the cathode line 5 are energized, an electric field is formed between the anode tube 4 and the cathode line 5. Under the action of the electric field, the surrounding gas is ionized to generate a large number of electrons and positive and negative ions. When the dust-containing flue gas and water mist enter the electric field, the dust particles are quickly charged under the action of the electrons and ions. Under the action of the electric field force, the charged dust particles quickly tend to the electrode with the opposite polarity. At the same time, the water mist in the flue gas will also be charged and collected together with the dust particles, so that the water mist and dust particles adhere to the inner wall of the anode tube 4. The water mist deposited on the inner wall of the anode tube 4 will form a layer of water film, which helps to keep the anode plate clean. During use, some dust will flow downward along with the water film on the inner wall of the anode tube 4 to complete its self-cleaning operation. During maintenance operations, the spray rack 11 can be used to spray and flush the anode tube 4 to keep the anode tube 4 in good use condition.

[0041] To solve the problem of filtering dusty liquid, Figure 4 As shown, the filter 14 includes a limit frame 18 and an adjustment frame 28. The adjustment frame 28 is movably installed on the inner side of the limit frame 18. The limit frame 18 is fixedly installed on the inner side of the liquid collecting bucket 12. Two groups of filter pads 16 are fixedly installed inside the adjustment frame 28. The filter pads 16 can be used to filter the dust-containing accumulated liquid discharged from the wet electrostatic precipitator. The setting of the adjustment frame 28 can move the two groups of filter pads 16 arbitrarily on the inner side of the limit frame 18, thereby adjusting the use position of the filter pads 16, so that the filter 14 can stably filter the dust-containing accumulated liquid discharged into the liquid collecting bucket 12.

[0042] like Figure 5 As shown, two groups of vacuum cleaners 17 for use with the filter pad 16 are fixedly installed on the outer surface of the upper end of the limiting frame 18, and drivers 15 for use with the adjustment frame 28 are provided in the middle of both sides of the limiting frame 18. By using the vacuum cleaner 17, the filter pad 16 can be vacuumed and cleaned when the filter pad 16 passes through the lower part of the vacuum cleaner 17, thereby removing the dust accumulated in the filter pad 16, so that the filter pad 16 can be used continuously.

[0043] like Figure 6As shown, the driver 15 includes a rotating rod 20, a driving wheel 21 and a motor 22. The rotating rod 20 is movably installed under the motor 22. The rotating rod 20 and the motor 22 are driven by gears. The driving wheel 21 is fixedly installed on the outer surface of one end of the rotating rod 20. The bottom of the adjustment frame 28 is provided with a tooth groove 19 used to cooperate with the driving wheel 21. The user starts the motor 22, so that the motor 22 drives the rotating rod 20 through the gear, so that the rotating rod 20 drives the driving wheel 21 to rotate, and the driving wheel 21 drives the adjusting frame 28 through the tooth groove 19, so that the adjusting frame 28 drives the filter pad 16 to translate.

[0044] To solve the cleaning problem of wet electrostatic precipitator, such as Figure 7 As shown, a moving frame 25 is movably installed on the inner side of the combined frame 13, and a moving slider 24 is movably installed on the inner side of the moving frame 25. The combined frame 13 and the moving frame 25 as well as the moving frame 25 and the moving slider 24 are driven by linear motors. The moving frame 25 is driven by the linear motor so that the moving frame 25 can translate on the inner side of the combined frame 13. The moving slider 24 is driven by another set of linear motors so that the moving slider 24 can translate on the inner side of the moving frame 25, thereby completing the two-way position adjustment of the cleaning ring 27, so that the cleaning ring 27 can be moved to the bottom of any anode tube 4.

[0045] like Figure 7 As shown, a cylinder body 23 is fixedly installed in the middle of the lower end of the movable slider 24, and the interior of the cylinder body 23 is a double-cavity structure. Two sets of lifting push rods 26 are movably sleeved on one end of the cylinder body 23. The lifting push rods 26 are driven by the cylinder body 23, so that the lifting push rods 26 can drive the cleaning ring 27 to move up and down, thereby completing the cleaning operation of the inner wall of the anode tube 4.

[0046] like Figure 8 As shown, a cleaning ring 27 is fixedly installed at the upper end of the two groups of lifting push rods 26, and the two groups of lifting push rods 26 are symmetrically arranged. The cleaning ring 27 is an overall circular ring structure, and the outer surface of the cleaning ring 27 is provided with an annular brush. Because the cathode wire 5 is provided in the middle of the anode tube 4, the arrangement of the two groups of lifting push rods 26 can avoid the cathode wire 5, and at the same time allow the cathode wire 5 to pass through the cleaning ring 27, thereby completing the cleaning operation of the anode tube 4.

[0047] A cover plate is provided on the outer surface of one side of the box shell 8 for use with the combination frame 13. The box shell 8 and the combination frame 13 are spliced ​​and fixed by means of a card slot. After opening the cover plate, the card slot structure can be used to complete the splicing and fixation between the box shell 8 and the combination frame 13. After the maintenance of the wet electrostatic precipitator is completed, the combination frame 13 can be taken out so that the wet electrostatic precipitator can be used normally.

[0048] When in use, the conventional wet electrostatic precipitator uses the water film generated by the operation of the equipment, or the spray structure or the vibration method to clean its dust collecting electrode structure. There are multiple sets of dust collecting electrode structures inside the wet electrostatic precipitator, which need to be cleaned regularly to ensure the use effect of the dust collecting electrode. Conventional cleaning structures are prone to residue, which reduces the self-cleaning effect of the wet electrostatic precipitator.

[0049] To this end, by providing a cleaning ring 27 and a moving frame 25, when the corona module and its wet electrostatic precipitator are used, they have a lifting inner wall cleaning structure, which can perform a self-cleaning operation on the dust collecting structure, thereby improving the use effect of the wet electrostatic precipitator;

[0050] During operation, the exhaust gas is introduced into the interior of the box shell 8 by using the air inlet nozzle 9. When the anode tube 4 and the cathode wire 5 are energized, an electric field is formed between the anode tube 4 and the cathode wire 5. The anode tube 4 is equivalent to a dust collecting electrode. Under the action of the electric field, the surrounding gas is ionized to generate a large number of electrons and positive and negative ions. When the dust-containing flue gas and water mist enter the electric field, the dust particles are quickly charged under the action of electrons and ions. The charged dust particles quickly tend to the electrode with the opposite polarity under the action of the electric field force. At the same time, the water mist in the flue gas will also be charged and collected together with the dust particles, so that the water mist and dust particles are attached to the inner wall of the anode tube 4.

[0051] After a period of use, dust will accumulate on the inner wall of the anode tube 4. At this time, the wet electrostatic precipitator is closed, and after the cover is opened, the card slot structure can be used to complete the splicing and fixing between the box shell 8 and the assembly frame 13, and the assembly frame 13 is installed under the anode tube 4. The linear motor is used to drive the moving frame 25 so that the moving frame 25 can translate on the inner side of the assembly frame 13, and another set of linear motors is used to drive the moving slider 24 so that the moving slider 24 can translate on the inner side of the moving frame 25, thereby completing the two-way position adjustment of the cleaning ring 27, so that the cleaning ring 27 can move to the bottom of any anode tube 4. The controller is programmed according to the number and position of the anode tubes 4, so that the cleaning ring 27 is moved to the bottom of all the anode tubes 4 in sequence. Because the cathode wire 5 is arranged in the middle of the anode tube 4, the two sets of lifting push rods 26 can avoid the cathode wire 5, and at the same time, the cathode wire 5 passes through the cleaning ring 27 to complete the cleaning operation of the anode tube 4. The cylinder body 23 is used to drive the lifting push rod 26, so that the lifting push rod 26 can drive the cleaning ring 27 to move up and down, thereby completing the cleaning operation of the inner wall of the anode tube 4. During the cleaning operation, the spray rack 11 can be used to flush the accumulated dust through the water body, thereby improving the cleaning effect of the anode tube 4.

[0052] Secondly, when the wet electrostatic precipitator is in use, it uses the water it generates to flush the captured dust into the ash hopper and discharge it with the water. During the self-cleaning operation, a large amount of dust will also be mixed in the water, making it impossible to directly discharge the dust-containing liquid, which increases the operating cost and maintenance difficulty of the equipment.

[0053] To this end, by setting the filter 14, when the corona module and its wet electrostatic precipitator are used, the use of the cleaning ring 27 and the spray rack 11 is optimized, so that it has a dust-containing liquid filtering structure, which can remove dust in the liquid and reduce the cost of equipment use;

[0054] During use, when the anode tube 4 and the cathode line 5 are energized, the electrostatic force can be used to absorb liquid and dust when the gas passes through the anode tube 4, so that the water mist and dust particles adhere to the inner wall of the anode tube 4. The water mist deposited on the inner wall of the anode tube 4 will form a layer of water film, which helps to keep the anode plate clean. During use, some dust will flow downward along with the water film on the inner wall of the anode tube 4. The flowing water is mixed with a large amount of dust. The filter pad 16 can be used to filter the dust-containing accumulated liquid discharged by the wet electrostatic precipitator, and the setting of the adjustment frame 28 can be The two groups of filter pads 16 can be arbitrarily moved on the inner side of the limiting frame 18 to adjust the use position of the filter pads 16, so that the two groups of filter pads are used alternately, so that the filter 14 can stably filter the dust-containing accumulated liquid discharged into the liquid collecting hopper 12. By using the vacuum cleaner 17, the filter pad 16 can be vacuumed and cleaned when it passes through the lower part of the vacuum cleaner 17, so as to remove the dust accumulated in the filter pad 16, so that the filter pad 16 can be used continuously, and at the same time, the sewage discharged when the cleaning ring 27 and the spray rack 11 are used can be filtered and processed.

[0055] Secondly, when the wet electrostatic precipitator is performing self-cleaning operation, the inner wall of the dust collecting electrode needs to be cleaned. Conventional dust collecting electrodes can only be cleaned by flushing and do not have a physical cleaning structure, which increases the difficulty of cleaning the dust collecting electrode.

[0056] To this end, by providing the anode tube 4 and the fixed base 2, when the corona module and its wet electrostatic precipitator are used, the use effect of the cleaning ring 27 can be improved;

[0057] Compared with the traditional non-columnar dust collecting electrode, the anode tube 4 with a columnar structure design can cooperate with the inner wall of the anode tube 4 with the annular brush when the cleaning ring 27 moves up and down to better complete the cleaning operation. At the same time, it can cooperate with the circular through hole 3 with a truncated cone structure to prevent the cleaning ring 27 from being misaligned when moving upward, so that the cleaning ring 27 can pass through the circular through hole 3 and be inserted into the inner wall of the anode tube 4, thereby improving the stability of the cleaning ring 27 when in use.
