The traditional wet electrostatic precipitator uses a water film, a spraying structure or a vibration mode generated by the operation of the equipment to clean the dust collecting electrode structure. However, the wet electrostatic precipitator is provided with multiple dust collecting electrode structures inside, which need to be cleaned regularly to ensure the use effect of the dust collecting electrode. The plate-shaped dust collecting electrode is not conducive to cleaning operation, and the conventional cleaning structure is prone to residual phenomenon, which reduces the self-cleaning effect of the wet electrostatic precipitator. SUMMARY

[0016] As a further technical scheme of the present application, the lower end of the moving slider is movably mounted with a cylinder body, the inside of the cylinder body is a double-cavity structure, one end of the cylinder body is movably sleeved with two groups of lifting jacks, the lifting jacks are driven by the cylinder body, so that the lifting jacks can drive the cleaning material ring to move up and down, thereby completing the cleaning operation of the inner wall of the anode tube.

[0017] As a further technical scheme of the present application, the upper end of the two groups of lifting jacks is movably mounted with a cleaning material ring, the two groups of lifting jacks are symmetrically arranged, the cleaning material ring is a circular ring structure, and the outer surface of the cleaning material ring is provided with an annular brush, because the middle part of the anode tube is provided with a cathode wire, the arrangement of the two groups of lifting jacks can avoid the cathode wire, and at the same time, the cathode wire passes through the cleaning material ring, thereby completing the cleaning operation of the anode tube.

[0018] As a further technical scheme of the present application, one side of the outer surface of the box shell is provided with a cover plate matched with the combination frame, the box shell and the combination frame are fixedly connected through the clamping groove, after the cover plate is opened, the clamping and fixing between the box shell and the combination frame can be completed through the clamping groove structure, after the maintenance of the wet electric dust collector is completed, the combination frame can be taken out, so that the wet electric dust collector can be normally used.

[0019] The present application has the following advantages:

[0020] 1. By arranging the anode tube and the fixed base, the use effect of the cleaning material ring can be improved when the corona module and the wet electric dust collector are used.

[0021] Compared with the traditional non-cylindrical structure of the dust collecting electrode, the anode tube designed in a cylindrical structure can make the cleaning material ring move up and down and cooperate with the annular brush to adhere to the inner wall of the anode tube, better completing the cleaning operation, and can cooperate with the circular through hole of the circular table structure, so that the cleaning material ring can pass through the circular through hole and be inserted into the inner wall of the anode tube when moving up, improving the stability of the cleaning material ring during use.

[0022] 2. By setting up a cleaning ring and a moving frame, the corona module and its wet electrostatic precipitator are equipped with a lifting inner wall cleaning structure, which can perform self-cleaning operation on the dust collection structure and improve the performance of the wet electrostatic precipitator.

[0023] During operation, exhaust gas is introduced into the interior of the housing through the air inlet. When the anode tube and cathode wire are energized, an electric field is formed between them. The anode tube acts as the dust collecting electrode. Under the action of the electric field, the surrounding gas is ionized, generating a large number of electrons and positive and negative ions. When dust-laden flue gas and water mist enter the electric field, the dust particles are rapidly charged under the action of electrons and ions. The charged dust particles are then rapidly attracted to the electrode with the opposite polarity under the action of the electric field. At the same time, the water mist in the flue gas is also charged and is collected together with the dust particles, causing the water mist and dust particles to 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 tubes. At this time, shut down the wet electrostatic precipitator, open the cover, and use the slot structure to connect and fix the outer shell and the assembly frame. Install the assembly frame below the anode tubes, and use a linear motor to drive the moving frame, allowing it to slide inside the assembly frame. Use another set of linear motors to drive the moving slider, allowing it to slide inside the moving frame. This allows for bidirectional adjustment of the cleaning ring's position, enabling it to move to the bottom of any anode tube. The system is programmed by a controller based on the number and position of the anode tubes, causing the cleaning ring to move sequentially to the bottom of all the anode tubes. Because the cathode wire is located in the middle of the anode tube, the two sets of lifting rods can avoid the cathode wire while allowing the cathode wire to pass through the cleaning ring, thus completing the cleaning operation of the anode tube. The lifting rod is driven by a cylinder, which in turn moves the cleaning ring 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 a spray frame to flush away the accumulated dust with water, improving the cleaning effect of the anode tube.

[0025] 3. By setting up filters, the use of cleaning rings and spray frames is optimized when the corona module and its wet electrostatic precipitator are used, so that it has a dust-laden liquid filtration structure, which can remove dust from the liquid and reduce the cost of equipment use.

[0026] When the anode tube and the cathode wire are powered, the liquid and dust can be adsorbed by the electrostatic force when the gas passes through the anode tube, so that the water mist and the dust particles adhere to the inner wall of the anode tube, and the water mist deposited on the inner wall of the anode tube forms a water film, which helps to keep the anode plate clean. During use, part of the dust will flow down with the water film on the inner wall of the anode tube, and the flowing water body mixed with a large amount of dust can be filtered by the filter pad, and the setting of the adjusting frame can move the two groups of filter pads on the inner side of the limiting 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 from the collecting bucket. By using the dust collector, the filter pad can be cleaned when passing through the lower part of the dust collector, so as to remove the accumulated dust in the filter pad, so that the filter pad can be continuously used, and the sewage discharged during use of the cleaning ring and the spraying frame can be filtered.

[0038] like Figure 1 As shown, a corona discharge module includes a fixed base 2, an anode tube 4, and a cathode wire 5. The number of anode tubes 4 and cathode wires 5 are several sets. The cathode wire 5 is located at the inner middle of the anode tube 4. The fixed base 2 is fixedly installed at the bottom of the anode tube 4. Several sets of anode tubes 4 are connected and fixed together by a fixed frame 6, which is fixedly sleeved on the outer side of the anode tube 4. Several sets of circular through holes 3 used with the anode tubes 4 are fixedly provided on the outer surface of the fixed base 2. The cross-section of the circular through holes 3 is a frustum-shaped structure. A splicing groove 1 is provided on the outer side of the fixed base 2, and a docking clip 7 is provided at one end of the fixed base 2. The splicing groove 1, in conjunction with the docking clip 7, allows the fixed base 2 to be assembled and fixed, thus facilitating the installation of any number of anode tubes 4.

[0039] like Figure 2 As shown, a wet electrostatic precipitator includes a housing 8 and a liquid collection hopper 12. The liquid collection hopper 12 is fixedly installed at the lower middle position of the housing 8. Several sets of anode tubes 4 are fixedly installed inside the housing 8. Cathode wires 5 are arranged in the middle of the inner side of the anode tubes 4. The lower ends of the several sets of anode tubes 4 are connected and fixed by a fixed base 2. A combination frame 13 is arranged inside the housing 8 below the fixed base 2. The housing 8 and the combination frame 13 are spliced ​​and fixed together. A filter 14 is fixedly installed inside the liquid collection hopper 12. A controller is installed on one side of the housing 8. The filter 14 can be used to filter the dust-laden liquid generated during the use of the wet electrostatic precipitator. The combination frame 13 can be used to install a cleaning structure. During the maintenance operation of the wet electrostatic precipitator, a cleaning ring 27 is installed inside the housing 8 to facilitate the physical cleaning of the inside of the anode tubes 4.

[0040] like Figure 3As shown, the inside of the box shell 8 is provided with a spray frame 11 above the anode tube 4, the upper end of the box shell 8 is fixedly installed with an exhaust nozzle 10, and the lower part of one side of the box shell 8 is fixedly installed with an air inlet nozzle 9. The exhaust gas is introduced into the inside of the box shell 8 by the air inlet nozzle 9. After 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. 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 charged under the action of the electrons and ions. The charged dust particles quickly tend to the electrode with opposite polarity under the action of the electric field force. At the same time, the water mist in the flue gas is also charged and collected together with the dust particles, so that the water mist and the 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 forms a layer of water film, which helps to keep the anode plate clean. During use, part of the dust will flow down with the water film on the inner wall of the anode tube 4, completing the self-cleaning operation. During maintenance, the anode tube 4 can be sprayed and washed by the spray frame 11 to keep it in good working condition.

[0041] To solve the problem of dust-containing accumulated liquid filtration, such as Figure 4 As shown, the filter 14 includes a limiting frame 18 and an adjusting frame 28. The adjusting frame 28 is movably installed on the inside of the limiting frame 18, and the limiting frame 18 is fixedly installed on the inside of the collecting bucket 12. Two groups of filter pads 16 are fixedly installed in the inside of the adjusting frame 28. The filter pads 16 can filter the dust-containing accumulated liquid discharged by the wet-type electric dust collector. The adjusting frame 28 can be arbitrarily moved on the inside of the limiting frame 18 with the two groups of filter pads 16, so as to adjust the use position of the filter pads 16, and the filter 14 can stably filter the dust-containing accumulated liquid discharged by the collecting bucket 12.

[0042] As shown in Figure 5 The upper end of the limiting frame 18 is fixedly installed with two groups of dust collectors 17 matched with the filter pads 16. The middle part of the two sides of the limiting frame 18 is provided with a driver 15 matched with the adjusting frame 28. The dust collector 17 can be used to clean the filter pads 16 when the filter pads 16 pass through the lower part of the dust collector 17, so as to remove the accumulated dust in the filter pads 16 and enable the filter pads 16 to be continuously used.

[0043] As shown in 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 below 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 adjusting frame 28 is provided with a tooth groove 19 matched with the driving wheel 21, the user starts the motor 22, so that the motor 22 drives the rotating rod 20 through the gears, and 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 the wet electric dust collector, such as Figure 7 As shown, the inner side of the combined frame 13 movably installs a moving frame 25, the inner side of the moving frame 25 movably installs a moving slider 24, the combined frame 13 and the moving frame 25 and the moving frame 25 and the moving slider 24 are driven by linear motors, the moving frame 25 is driven by the linear motor to move, so that the moving frame 25 can translate in the inner side of the combined frame 13, another set of linear motors are used to drive the moving slider 24, so that the moving slider 24 can translate in the inner side of the moving frame 25, thereby completing the bidirectional position adjustment of the cleaning ring 27, so that the cleaning ring 27 can move to the lower side of any one of the anode pipes 4.

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

[0046] As shown in Figure 8 The upper end of the two sets of lifting jacks 26 is fixedly installed with a cleaning ring 27, the two sets of lifting jacks 26 are symmetrically arranged, the overall structure of the cleaning ring 27 is a circular ring, and the outer surface of the cleaning ring 27 is provided with an annular brush, because the middle part of the anode pipe 4 is provided with a cathode wire 5, the arrangement of the two sets of lifting jacks 26 can avoid the cathode wire 5, and the cathode wire 5 passes through the cleaning ring 27, thereby completing the cleaning operation of the anode pipe 4.

[0047] One side of the outer surface of the box shell 8 is provided with a cover plate matched with the combined frame 13, the box shell 8 and the combined frame 13 are fixedly spliced by the clamping groove, after the cover plate is opened, the splicing and fixing between the box shell 8 and the combined frame 13 can be completed by the clamping groove structure, after the maintenance of the wet electric dust collector is completed, the combined frame 13 can be taken out, so that the wet electric dust collector can be normally used.

[0048] In use, the traditional wet electric dust collector uses the water film generated by the operation of the equipment or the spray structure or the vibration to clean the dust collecting pole structure, and the wet electric dust collector is provided with multiple groups of dust collecting pole structures, which need to be cleaned regularly to ensure the use effect of the dust collecting pole, and the conventional cleaning structure is easy to have residual phenomenon, which reduces the self-cleaning effect of the wet electric dust collector.

[0049] Therefore, by arranging the cleaning ring 27 and the moving frame 25, the wet electric dust collector and the corona module have a lifting inner wall cleaning structure during use, which can perform self-cleaning operation on the dust collecting structure and improve the use effect of the wet electric dust collector.

[0050] In operation, the waste gas is introduced into the inside of the box shell 8 through the gas inlet nozzle 9, and when the anode tube 4 and the cathode wire 5 are electrified, an electric field is formed between the anode tube 4 and the cathode wire 5, and the anode tube 4 serves as a dust collecting pole. 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 charged under the action of the electrons and ions, and the charged dust particles are rapidly attracted to the electrode with opposite polarity under the action of the electric field force. At the same time, the water mist in the flue gas is also charged and collected together with the dust particles, so that the water mist and the dust particles adhere 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 electric dust collector is turned off, the cover plate is opened, and the splicing and fixing between the box shell 8 and the combined frame 13 can be completed by using the clamping groove structure. The combined frame 13 is installed below the anode tube 4, the moving frame 25 is driven by the linear motor so that the moving frame 25 can translate in the inside of the combined frame 13, the moving slider 24 is driven by another linear motor so that the moving slider 24 can translate in the inside of the moving frame 25, thereby completing the bidirectional position adjustment of the cleaning ring 27, so that the cleaning ring 27 can move below any one of the anode tubes 4. The controller is programmed according to the number and position of the anode tubes 4, and the cleaning ring 27 moves below all the anode tubes 4 in turn. Because the middle part of the anode tube 4 is provided with the cathode wire 5, the two groups of lifting jacks 26 can avoid the cathode wire 5, and the cathode wire 5 passes through the cleaning ring 27, thereby completing the cleaning operation of the anode tube 4. The lifting jacks 26 are driven by the cylinder body 23, so that the lifting jacks 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. The cleaning operation can be used in cooperation with the spray frame 11 to perform the flushing operation on the accumulated dust by the water body, thereby improving the cleaning effect of the anode tube 4.

[0052] Secondly, when the wet electrostatic precipitator is in use, the water body generated by itself is used to flush the captured dust into the ash bucket and discharge with water, and during the self-cleaning operation, a large amount of dust will also be mixed in the water body, so that the dust-containing liquid cannot be directly discharged, increasing the operation cost and maintenance difficulty of the equipment;

[0053] Therefore, by arranging the filter 14, the use of the cleaning ring 27 and the spray frame 11 is optimized during the use of the corona module and the wet electrostatic precipitator thereof, so that the dust-containing liquid filtering structure can remove the dust in the liquid and reduce the equipment use cost;

[0054] During use, when the anode tube 4 and the cathode wire 5 are electrified, the liquid and dust can be adsorbed by electrostatic force 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 forms a water film, which helps to keep the anode plate clean. During use, part of the dust will flow down with the water film on the inner wall of the anode tube 4. The flowing water body is mixed with a large amount of dust. The filter pad 16 can filter the dust-containing accumulated liquid discharged by the wet electrostatic precipitator. The adjustment frame 28 can be arbitrarily moved inside the limiting frame 18. Two sets of filter pads 16 are arranged to adjust the use position of the filter pad 16, so that the two sets of filter pads are used alternately. The filter 14 can stably filter the dust-containing accumulated liquid discharged to the liquid collecting bucket 12. By arranging the dust collector 17, the filter pad 16 can be cleaned when it passes through the lower part of the dust collector 17, so as to remove the accumulated dust in the filter pad 16. The filter pad 16 can be continuously used, and the sewage discharged during the use of the cleaning ring 27 and the spray frame 11 can be filtered.

[0055] Secondly, when the wet electrostatic precipitator is in use, the water body generated by itself is used to flush the captured dust into the ash bucket and discharge with water, and during the self-cleaning operation, a large amount of dust will also be mixed in the water body, so that the dust-containing liquid cannot be directly discharged, increasing the operation cost and maintenance difficulty of the equipment;

[0056] Therefore, by arranging the filter 14, the use of the cleaning ring 27 and the spray frame 11 is optimized during the use of the corona module and the wet electrostatic precipitator thereof, so that the dust-containing liquid filtering structure can remove the dust in the liquid and reduce the equipment use cost;

[0057] Compared with the conventional non-columnar structure of the dust collecting electrode, the anode tube 4 with a columnar structure design can cooperate with the annular brush to better complete the cleaning operation when the cleaning ring 27 moves up and down, and can cooperate with the circular through hole 3 with a circular table structure, 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, improving the stability of the cleaning ring 27 during use.

[0058] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application in any form. Although the present application has been disclosed with the preferred embodiments as above, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above disclosed technical content to obtain equivalent embodiments with equivalent changes, as long as the changes or modifications do not deviate from the technical solution of the present application. Any modification, change, equivalent change and modification of the above embodiments made according to the technical essence of the present application still belong to the scope of the technical solution of the present application.
