Description

Technical Field

[0001] This invention belongs to the field of ozone generation technology, specifically a highly efficient and energy-saving ozone dual-gap discharge electrode and ozone generator. Background Technology

[0002] The high-efficiency and energy-saving ozone dual-gap discharge electrode and matching ozone generator continuously produce ozone by ionizing oxygen through a high-voltage and high-frequency electric field. The equipment can stably produce high-purity ozone gas, realizing on-site instant ozone generation. Ozone has strong oxidizing properties and can naturally revert to oxygen after disinfection and oxidation treatment, leaving no chemical residue. It is a green and environmentally friendly core equipment for oxidation treatment.

[0003] A Chinese patent with publication number CN114760746A discloses a plasma generating unit and a plasma ozone generating device. The plasma generating unit includes at least: a low-voltage electrode plate coated with insulating dielectric sheets on both sides; a high-voltage electrode plate coated with the insulating dielectric sheets on both sides, wherein the high-voltage electrode plate is arranged parallel to the low-voltage electrode plate and the low-voltage electrode plate is spirally wound with the high-voltage electrode plate; and a housing covering the low-voltage electrode plate and the high-voltage electrode plate, wherein the housing seals both ends of the high-voltage electrode plate and the low-voltage electrode plate, and a discharge channel is formed between adjacent low-voltage electrode plates and the high-voltage electrode plate. The plasma generating unit and plasma ozone generating device provided by this invention can effectively generate high-concentration ozone water.

[0004] Existing dielectric barrier discharge ozone generators generally adopt a single-gap discharge structure, which limits the effective discharge area and results in low ozone generation efficiency. Furthermore, the glass dielectric tube is easily damaged by vibration and impact during transportation and operation, and the overall heat dissipation performance is poor, making it difficult to quickly dissipate the heat generated by the discharge. High-temperature environments will accelerate ozone decomposition and loss. At the same time, the single-gap structure has insufficient power utilization, resulting in lower ozone output for the same power consumption. There is still considerable room for optimization in terms of equipment energy consumption and production capacity.

[0005] Therefore, the present invention provides a highly efficient and energy-saving ozone dual-gap discharge electrode and an ozone generator. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies and solve the problem of low ozone output under the same power consumption, this invention proposes a high-efficiency and energy-saving ozone dual-gap discharge electrode and ozone generator.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A high-efficiency and energy-saving ozone dual-gap discharge electrode, comprising an outer electrode, a special glass dielectric tube passing through the outer electrode, an auxiliary electrode mesh layer passing through the special glass dielectric tube, an inner electrode passing through the auxiliary electrode mesh layer, and an electrode connector connecting the outer electrode and the auxiliary electrode mesh layer. The outer electrode, the special glass dielectric tube, the auxiliary electrode mesh layer, and the inner electrode are coaxially arranged. A first discharge gap exists between the outer electrode and the special glass dielectric tube, and a second discharge gap exists between the inner electrode and the auxiliary electrode mesh layer. The outer electrode is grounded. One end of the electrode connector is connected to a threaded rod, and an adjusting nut is threaded onto the outer surface of the threaded rod.

[0008] By adopting the above scheme, coolant is introduced into the insulating shell to control the device temperature and control the air compressor to compress and deliver air into the cavity. The output end of the air compressor is connected to the first and second discharge gaps through a pipe, allowing oxygen-containing gas to enter the first and second discharge gaps. Then, the high-voltage high-frequency power supply is started, and dielectric barrier discharge is generated simultaneously in the two discharge gaps. Oxygen is directly generated into ozone under the action of discharge. The generated ozone is discharged through a connecting pipe and collected through a storage tank. During operation, the power supply voltage and frequency are adjusted according to the load to optimize the ozone generation efficiency. The dual-gap structure increases the effective discharge area and significantly improves the ozone yield. The auxiliary electrode mesh layer balances the electric field and avoids local over-discharge. The coolant can enhance heat dissipation and prevent ozone thermal decomposition. The overall energy efficiency is better than that of traditional single-gap ozone generators, and electrical energy can be fully utilized.

[0009] Preferably, a micro-gap gap of 0.1mm to 0.3mm is left between the auxiliary electrode mesh layer and the inner wall of the special glass dielectric tube, the first discharge gap gap is 0.2mm to 0.8mm, the second discharge gap gap is 0.2mm to 0.6mm, and a flow guiding spacer is provided in the first and second discharge gaps to guide the airflow along the axial direction.

[0010] A high-efficiency and energy-saving ozone generator includes an insulating housing, a high-voltage high-frequency power supply fixedly disposed within the insulating housing, a partition plate fixedly disposed within the insulating housing, an array of limit rings disposed on the partition plate, an outer electrode passing through the limit rings, a conductive plate sleeved on a threaded rod, and adjacent threaded rods connected by the conductive plate, a coolant discharge assembly disposed on the side of the insulating housing, a controller disposed on the front of the insulating housing, a sealing assembly disposed on the insulating housing, the high-voltage high-frequency power supply output voltage of 3kV to 20kV and frequency of 5kHz to 50kHz, a storage assembly for storing ozone disposed on the side of the insulating housing, a grounding assembly disposed within the insulating housing, an inner electrode and an auxiliary electrode mesh layer both connected to the output terminal of the high-voltage high-frequency power supply, and an air compressor fixedly disposed on the side of the insulating housing.

[0011] By adopting the above scheme, the insulating shell provides installation space for the high-efficiency and energy-saving ozone dual-gap discharge electrode. The partition plate can limit the position of the external electrode through the limiting ring. The external electrode can be connected to the power supply in parallel through the conductive sheet. Coolant can be added to or discharged into the insulating shell through the coolant discharge component. The controller is electrically connected to the electronic equipment and can control the operation of the electronic equipment through the controller. The grounding component can assist the external grounding wire of the external electrode. The air compressor can compress and deliver oxygen-containing air into the discharge gap for reaction processing.

[0012] Preferably, the coolant discharge assembly includes a coolant inlet head and a coolant outlet head, which are connected to the side of the insulating housing and are arranged symmetrically above and below each other.

[0013] By adopting the above scheme, coolant can be easily added into the insulating housing through the coolant inlet head, and the coolant can be discharged through the coolant outlet head.

[0014] Preferably, the sealing assembly includes a top cover and a sealing block, the top cover being hinged to the top of the insulating housing, and the sealing block being fixed to the bottom of the top cover.

[0015] By adopting the above solution, the top cover can be rotated easily through the hinge, making it convenient to adjust the position of the top cover. After the top cover is moved above the insulating shell, the top of the insulating shell can be sealed by the sealing block.

[0016] Preferably, the storage component includes a storage tank and a connecting pipe. The storage tank is fixed to the side of the insulating shell. One end of the connecting pipe is connected to the storage tank, and the other end of the connecting pipe is connected to the first discharge gap and the second discharge gap through a pipe. A solenoid valve is provided at the connection between the storage tank and the connecting pipe.

[0017] By adopting the above scheme, the opening and closing state of the connecting pipe can be controlled by the solenoid valve. The connecting pipe is connected to the first discharge gap and the second discharge gap through the pipeline. When ozone is generated, the generated ozone flows into the interior of the connecting pipe through the pipeline. The ozone can then be stored inside the storage tank through the connecting pipe, thus achieving the purpose of collecting the generated ozone. The storage tank is detachable.

[0018] Preferably, the insulating housing has a through groove on the front side, a storage groove on the bottom of the insulating housing, and one end of the storage groove extends into the through groove. A sealing ring is provided between the storage groove and the through groove. Positioning holes are arranged in an array on the side of the storage groove. A positioning bolt is threaded into the insulating housing, and one end of the positioning bolt extends into the positioning hole.

[0019] By adopting the above scheme, the precipitates generated inside the insulating shell will be stored in the storage tank. When cleaning the inside of the insulating shell, the coolant stored inside is drained through the coolant drain head. Then, the positioning bolt is rotated so that the positioning bolt moves out of the positioning hole and the storage tank is no longer positioned. The storage tank is then pulled and moved to the outside through the through slot, so that the precipitates can be cleaned.

[0020] Preferably, the grounding assembly includes a threaded head, a metal plate, and a threaded sleeve. The metal plate array is disposed inside the insulating housing. The threaded head is fixedly connected to the bottom end of the outer electrode. The threaded sleeve is rotatably disposed on the metal plate, and the outer surface of the threaded head is threadedly connected to the inside of the threaded sleeve.

[0021] By adopting the above scheme, after the threaded head and the threaded sleeve are connected by threads, the external electrode can be grounded through the metal plate, and the threaded sleeve can rotate on the metal plate.

[0022] Preferably, the bottom of the metal plate is connected to a sealing box corresponding to the threaded sleeve. A dual-output shaft motor is fixedly installed inside the sealing box. One output end of the dual-output shaft motor is fixedly connected to a connecting shaft, and the other end of the connecting shaft is fixedly connected to the center position of the threaded sleeve. An installation box is fixedly connected to the bottom of the sealing box. A micro water pump is fixedly installed inside the installation box. The other output end of the dual-output shaft motor is fixedly connected to a driven shaft, and the other end of the driven shaft is drivenly connected to the micro water pump. The output end of the micro water pump is connected to a delivery pipe. An annular groove is provided on the threaded sleeve. A guide ring corresponding to the annular groove is fixedly installed inside the metal plate, and the guide ring engages with the annular groove. The guide ring is hollow. The other end of the delivery pipe is connected to the guide ring. A drain outlet is provided on the guide ring. A connecting groove is symmetrically arranged inside the threaded sleeve, and the other end of the connecting groove is connected to the annular groove.

[0023] By adopting the above scheme, the sealing box is used to seal and protect the dual-output shaft motor. When it is necessary to disassemble and maintain a single damaged external electrode, controlling the dual-output shaft motor will drive the connecting shaft to rotate. When the connecting shaft rotates, it will drive the threaded sleeve to rotate. At the same time, the driven shaft will drive the micro water pump to move. When the threaded sleeve rotates, the annular groove and the guide ring will cooperate to guide the threaded sleeve, so that the threaded sleeve rotates smoothly. When the threaded sleeve rotates, the corresponding external electrode position can be limited by manual tools, so that the thread head can be separated from the threaded sleeve. The single damaged external electrode can be disassembled and maintained, which improves the maintenance efficiency. It does not require the whole disassembly for maintenance, which improves the work efficiency. When the micro water pump is working, it draws coolant from inside the insulating shell. The drawn coolant is transported and can flow into the guide ring through the delivery pipe. Through the drain port, the coolant flows into the annular groove, and then the water source can flow into the annular groove.

[0024] Preferably, the threaded sleeve is symmetrically provided with support plates, a scraper is fixedly provided on the support plates, and the other side of the scraper is in contact with the surface of the outer electrode. A flow divider is provided inside the support plate, and the flow divider is connected to the connecting groove. A nozzle is arrayed on the flow divider.

[0025] By adopting the above scheme, the rotation of the threaded sleeve will drive the rotation of the support plate, which in turn will drive the scraper to move. The scraper will clean the adsorbed substances on the surface of the external electrode, ensuring the cleanliness of the external electrode. The water source pumped by the micro water pump flows into the distribution tank through the connecting groove, and then the water source will be sprayed onto the surface of the external electrode on one side through the nozzle, which will further ensure the cleanliness of the external electrode. This allows the electrode to discharge evenly and stably, eliminates the risk of arcing and breaking down the glass medium, improves the water cooling heat exchange effect of the external electrode, reduces ozone high-temperature decomposition, increases ozone production efficiency, reduces equipment energy consumption, ensures good conductivity between the grounding screw and the metal contact surface, prevents electric field interference caused by potential shift between electrodes, delays corrosion and aging of stainless steel electrodes, and reduces maintenance costs for downtime and electrode replacement.

[0026] Preferably, a filter box is fixedly installed on the side of the mounting box, a water trough is provided inside the filter box, and one end of the water trough is connected to the mounting box. A sewage discharge trough is provided in the water trough, a filter plate is fixedly installed in the water trough, a load-bearing plate is fixedly installed in the filter box, a protective box is fixedly installed in the load-bearing plate, a waterproof electric push rod is fixedly installed in the protective box, and the telescopic end of the waterproof electric push rod extends into the water trough. A cleaning plate is fixedly connected to the telescopic end of the waterproof electric push rod, and the side of the cleaning plate is in contact with the side of the filter plate.

[0027] By adopting the above scheme, when the micro water pump is working to extract the liquid medium, the coolant inside the insulating shell will flow into the water tank. Before the coolant enters the installation box, the filter plate will filter the fluid to achieve the purpose of cleaning the rinsing liquid. Later, when removing the impurities filtered and intercepted on the surface of the filter plate, the waterproof electric push rod is controlled to adjust the position of the cleaning plate. When the cleaning plate moves, it will remove the impurities adsorbed on the surface of the filter plate. The removed impurities will fall to the outside through the drain tank and fall into the storage tank for storage. The micro water pump can also be started separately to extract and transfer the coolant. This process can be repeated to filter the coolant, which reduces the amount of floating matter in the coolant to a certain extent, thus reducing its impact on ozone production. The filter plate is also detachable and can be maintained regularly. When too many impurities are adsorbed on the filter plate, affecting the filtration effect, the filter plate can be disassembled and replaced.

[0028] The beneficial effects of this invention are as follows: 1. The present invention discloses a high-efficiency and energy-saving ozone dual-gap discharge electrode and ozone generator, which can adjust the power output voltage and frequency in real time according to the load conditions, so that the ozone generation conditions are always maintained in the optimal range. The dual-gap discharge structure significantly increases the total effective discharge area and significantly improves the ozone production efficiency. The addition of an auxiliary electrode mesh layer can balance the electric field distribution and effectively avoid the phenomenon of local concentrated over-discharge. The matching coolant circulation heat dissipation structure enhances the heat exchange capacity and suppresses ozone high-temperature decomposition loss. The overall power utilization rate is much higher than that of traditional single-gap ozone generators, and the energy-saving effect is outstanding.

[0029] 2. The high-efficiency and energy-saving ozone dual-gap discharge electrode and ozone generator of the present invention, when a damaged single external electrode needs to be disassembled and repaired separately, starts a dual-output shaft motor to drive the connecting shaft to rotate. The connecting shaft synchronously drives the threaded sleeve to rotate. During the rotation of the threaded sleeve, the annular groove and the guide ring cooperate to achieve radial limiting and guidance, ensuring that the threaded sleeve rotates smoothly and coaxially. During repair, the target external electrode is circumferentially limited with the help of tools, so that the threaded head at the bottom of the electrode can be loosened and separated from the threaded sleeve. This allows for independent disassembly and maintenance of a single faulty external electrode without disassembling the entire electrode module, greatly simplifying the repair process and effectively improving the efficiency of equipment maintenance.

[0030] 3. The present invention provides a high-efficiency and energy-saving ozone dual-gap discharge electrode and ozone generator. During the rotation of the threaded sleeve, the support plate is driven to rotate synchronously. The support plate further drives the scraper to scrape along the circumference of the outer wall of the outer electrode. The scraping action of the scraper automatically removes the impurities adsorbed on the surface of the outer electrode, continuously maintaining the cleanliness of the outer electrode surface and ensuring the stability of electrode discharge and grounding performance.

[0031] 4. The present invention discloses a high-efficiency and energy-saving ozone dual-gap discharge electrode and ozone generator. A micro water pump draws cooling water, which flows through a connecting groove and into a diversion groove. The water is then sprayed directionally by nozzles to rinse the surface of the outer electrode, further removing impurities attached to the electrode and continuously maintaining the cleanliness of the outer electrode. This not only ensures uniform and stable electrode discharge and avoids the risk of arcing and breaking down the glass medium, but also enhances the water-cooled heat exchange performance of the outer electrode, reduces ozone high-temperature decomposition loss, improves ozone production efficiency, and reduces equipment operating energy consumption. At the same time, it ensures stable conductivity between the grounding screw and the metal contact surface, avoids electric field interference caused by potential shift between electrodes, delays corrosion and aging of stainless steel electrodes, and effectively reduces the frequency of equipment downtime and the maintenance cost of electrode replacement.

[0032] 5. The present invention discloses a high-efficiency and energy-saving ozone dual-gap discharge electrode and ozone generator. A micro water pump draws coolant from the insulating housing and circulates it. The coolant is filtered and purified as it flows through the filter plate, removing suspended impurities from the liquid. A waterproof electric push rod can drive the cleaning plate to move, automatically scraping off the dirt trapped on the surface of the filter plate. The impurities fall into the storage tank through the drain trough for centralized collection. The micro water pump can also operate independently to continuously circulate and filter the coolant, reducing the accumulation of floating impurities in the coolant and preventing impurities from affecting the ozone preparation process. At the same time, the filter plate adopts a detachable structure, which is convenient for regular maintenance and replacement, and continuously ensures the cleanliness of the coolant.

[0036] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0037] like Figures 1 to 10 As shown in the embodiment of the present invention, a high-efficiency and energy-saving ozone dual-gap discharge electrode includes an outer electrode 1, a special glass dielectric tube 2 passing through the outer electrode 1, an auxiliary electrode mesh layer 3 passing through the special glass dielectric tube 2, and an inner electrode 4 passing through the auxiliary electrode mesh layer 3.

The output end of the air compressor 42 is connected to the first and second discharge gaps through a pipe, allowing oxygen-containing gas to enter the first and second discharge gaps. Then, the high-voltage high-frequency power supply 15 is started, and dielectric barrier discharge is generated simultaneously in the two discharge gaps. Oxygen is directly generated into ozone under the action of discharge. The generated ozone is discharged through the connecting pipe 20 and collected through the storage tank 19. During operation, the power supply voltage and frequency are adjusted according to the load to optimize the ozone generation efficiency. The double-gap structure increases the effective discharge area and significantly improves the ozone yield. The auxiliary electrode mesh layer 3 balances the electric field and avoids local over-discharge. The coolant can enhance heat dissipation and prevent ozone thermal decomposition. The overall energy efficiency is better than that of traditional single-gap ozone generators, and electrical energy can be fully utilized.

A storage assembly for storing ozone is provided on the side of the insulating housing 10. A grounding assembly is provided inside the insulating housing 10. The inner electrode 4 and the auxiliary electrode mesh layer 3 are both connected to the output terminal of the high-voltage high-frequency power supply 15.

[0042] Furthermore, the coolant discharge assembly includes a coolant inlet head 11 and a coolant outlet head 12, which are connected to the side of the insulating housing 10 and are arranged symmetrically in the upper and lower parts of the housing.

[0043] Coolant can be easily added into the insulating housing 10 through the coolant inlet head 11, and the coolant can be discharged through the coolant outlet head 12.

[0044] Furthermore, the sealing assembly includes a top cover 17 and a sealing block 18, with the top cover 17 connected to the top of the insulating housing 10 via a hinge and the sealing block 18 fixed to the bottom of the top cover 17.

[0045] The hinge facilitates the rotation of the top cover 17, making it easy to adjust its position. After the top cover 17 is moved above the insulating housing 10, the top of the insulating housing 10 can be sealed by the sealing block 18.

[0047] The opening and closing state of the connecting pipe 20 can be controlled by the solenoid valve. The connecting pipe 20 is connected to the first discharge gap and the second discharge gap through the pipe. When ozone is generated, the generated ozone flows into the interior of the connecting pipe 20 through the pipe. The ozone can be stored inside the storage tank 19 through the connecting pipe 20 to achieve the purpose of collecting the generated ozone. The storage tank 19 is detachable.

[0048] Furthermore, the insulating housing 10 has a through groove 21 on its front side and a storage groove 22 on its bottom, with one end of the storage groove 22 extending into the through groove 21. A sealing ring is provided between the storage groove 22 and the through groove 21. Positioning holes 23 are arranged in an array on the side of the storage groove 22. A positioning bolt 24 is threaded into the insulating housing 10, with one end of the positioning bolt 24 extending into the positioning hole 23.

[0049] When sediment is generated inside the insulating shell 10, it will be stored in the storage tank 22. When cleaning the inside of the insulating shell 10, the coolant stored inside is drained through the coolant drain head 12. Then, the positioning bolt 24 is rotated so that the positioning bolt 24 moves out of the positioning hole 23 and the storage tank 22 is no longer positioned. Then, the storage tank 22 is pulled and moved to the outside through the through groove 21, so that the sediment can be cleaned.

[0050] Furthermore, the grounding assembly includes a threaded head 9, a metal plate 25, and a threaded sleeve 33. The metal plate 25 is arranged in an array inside the insulating housing 10. The threaded head 9 is fixedly connected to the bottom end of the outer electrode 1. The threaded sleeve 33 is rotatably mounted on the metal plate 25, and the outer surface of the threaded head 9 is threadedly connected to the inside of the threaded sleeve 33.

[0051] After the threaded head 9 is threadedly connected to the threaded sleeve 33, the external electrode 1 can be grounded through the metal plate 25, and the threaded sleeve 33 can rotate on the metal plate 25.

[0052] Furthermore, the bottom of the metal plate 25 is connected to a sealing box 26 corresponding to the threaded sleeve 33. A dual-output shaft motor 27 is fixedly installed inside the sealing box 26. One output end of the dual-output shaft motor 27 is fixedly connected to a connecting shaft 28, and the other end of the connecting shaft 28 is fixedly connected to the center position of the threaded sleeve 33. A mounting box 29 is fixedly connected to the bottom of the sealing box 26. A micro water pump 30 is fixedly installed inside the mounting box 29. The other output end of the dual-output shaft motor 27 is fixedly connected to a driven shaft 31, and the other end of the driven shaft 31 is fixedly connected to a driven shaft 30. The end is connected to the micro water pump 30 for transmission. The output end of the micro water pump 30 is connected to the delivery pipe 32. The threaded sleeve 33 is provided with an annular groove 34. The metal plate 25 is fixedly provided with a guide ring 35 corresponding to the annular groove 34, and the guide ring 35 is engaged with the annular groove 34. The guide ring 35 is hollow.

The threaded sleeve 33 is symmetrically provided with a connecting groove 37, and the other end of the connecting groove 37 is connected to the annular groove 34.

[0053] The sealing box 26 is used to seal and protect the dual-output shaft motor 27. When it is necessary to disassemble and maintain the individually damaged external electrode 1, controlling the dual-output shaft motor 27 will drive the connecting shaft 28 to rotate. When the connecting shaft 28 rotates, it will drive the threaded sleeve 33 to rotate. At the same time, the driven shaft 31 will drive the micro water pump 30 to move. When the threaded sleeve 33 rotates, the annular groove 34 and the guide ring 35 will cooperate to guide the threaded sleeve 33, so that the threaded sleeve 33 rotates smoothly. When the threaded sleeve 33 rotates, the corresponding position of the external electrode 1 can be limited by manual tools, so that the thread head 9 can be separated from the threaded sleeve 33. The individually damaged external electrode 1 can be disassembled and maintained, which improves the maintenance efficiency and eliminates the need for overall disassembly, thus improving work efficiency.

[0054] When the micro water pump 30 is working, it draws coolant from inside the insulating housing 10. The drawn coolant is transported and can flow into the guide ring 35 through the transport pipe 32.

[0055] Furthermore, a support plate 38 is symmetrically arranged on the threaded sleeve 33, and a scraper 39 is fixedly arranged on the support plate 38. The other side of the scraper 39 is in contact with the surface of the outer electrode 1. A diversion groove 40 is arranged inside the support plate 38, and the diversion groove 40 is connected to the connecting groove 37. A nozzle 41 is arranged in an array on the diversion groove 40.

[0056] When the threaded sleeve 33 rotates, it will drive the support plate 38 to rotate. When the support plate 38 rotates, it will drive the scraper 39 to move. When the scraper 39 moves, it will clean the adsorbed substances on the surface of the external electrode 1, ensuring the cleanliness of the external electrode 1. The water pumped by the micro water pump 30 flows into the diversion tank 40 through the connecting channel 37. The water is then sprayed onto the surface of the outer electrode 1 through the nozzle 41, which further ensures the cleanliness of the outer electrode 1. This allows for uniform and stable electrode discharge, eliminates the risk of arcing and breaking down the glass medium, improves the water-cooled heat exchange effect of the outer electrode 1, reduces ozone decomposition at high temperatures, increases ozone production efficiency, reduces equipment energy consumption, ensures good conductivity between the grounding screw and the metal contact surface, prevents electric field interference caused by potential shift between electrodes, delays corrosion and aging of stainless steel electrodes, and reduces maintenance costs for downtime and electrode replacement.

[0057] Furthermore, a filter box 43 is fixedly installed on the side of the installation box 29. A water trough 44 is installed inside the filter box 43, and one end of the water trough 44 is connected to the installation box 29. A sewage discharge trough 45 is installed inside the water trough 44. A filter plate 46 is fixedly installed inside the water trough 44. A load-bearing plate 47 is fixedly installed inside the filter box 43. A protective box 48 is fixedly installed inside the load-bearing plate 47. A waterproof electric push rod 49 is fixedly installed inside the protective box 48, and the telescopic end of the waterproof electric push rod 49 extends into the water trough 44. A cleaning plate 50 is fixedly connected to the telescopic end of the waterproof electric push rod 49, and the side of the cleaning plate 50 is in contact with the side of the filter plate 46.

[0058] The water tank 44 is connected to the inside of the installation box 29. When the micro water pump 30 is working to draw liquid medium, the coolant inside the insulating shell 10 will flow into the water tank 44. Before the coolant enters the installation box 29, the filter plate 46 will filter the fluid to achieve the purpose of cleaning the rinsing liquid. Later, when removing the impurities filtered and intercepted on the surface of the filter plate 46, the waterproof electric push rod 49 is controlled to work, which will adjust the position of the cleaning plate 50. When the cleaning plate 50 moves, it will remove the impurities adsorbed on the surface of the filter plate 46. The removed impurities will fall to the outside through the drain trough 45 and fall into the storage tank 22 for storage. The micro water pump 30 can also be started separately to draw and transfer the coolant. This process can be repeated to filter the coolant, which reduces the amount of floating matter in the coolant to a certain extent and affects the ozone production. The filter plate 46 is detachable and can be maintained regularly. When too many impurities are adsorbed on the filter plate 46 and affect the filtration effect, the filter plate 46 can be disassembled and replaced.

[0059] Working Principle: First, coolant is conveniently added to the interior of the insulating housing 10 through the coolant inlet head 11, controlling the device temperature and controlling the air compressor 42 to compress and deliver air. The output end of the air compressor 42 is connected to the first and second discharge gaps through a pipe, allowing oxygen-containing gas to enter the first and second discharge gaps. Then, the high-voltage high-frequency power supply 15 is started, simultaneously generating dielectric barrier discharge in the two discharge gaps. Oxygen is directly generated into ozone under the action of discharge. The generated ozone is discharged through the connecting pipe 20 and collected through the storage tank 19. During operation, the power supply voltage and frequency are adjusted according to the load to optimize ozone generation efficiency. The dual-gap structure increases the effective discharge area and significantly improves the ozone yield. The auxiliary electrode mesh layer 3 balances the electric field and avoids local over-discharge. The coolant enhances heat dissipation and prevents ozone thermal decomposition, resulting in better overall energy efficiency than traditional single-gap ozone generators. It fully utilizes electrical energy. Deposits generated inside the insulating housing 10 are stored in the storage tank 22. When cleaning the inside of the insulating housing 10, the coolant is drained through the coolant drain head 12. Then, the positioning bolt 24 is rotated, moving it out of the positioning hole 23, thus removing the positioning of the storage tank 22. This allows the storage tank 22 to be moved to the outside through the through slot 21, facilitating the cleaning of the deposited precipitates. The sealing box 26 provides sealing protection for the dual-output shaft motor 27. When disassembling and maintaining a separately damaged external electrode 1, the dual-output shaft motor is controlled... The operation of shaft 27 will drive the connecting shaft 28 to rotate, which in turn will drive the threaded sleeve 33 to rotate. Simultaneously, the driven shaft 31 will drive the micro water pump 30 to move. When the threaded sleeve 33 rotates, the annular groove 34 and guide ring 35 will cooperate to guide the threaded sleeve 33, ensuring smooth rotation. During the rotation of the threaded sleeve 33, tools can be used to limit the position of the corresponding external electrode 1, thereby separating the threaded head 9 from the threaded sleeve 33. This allows for the disassembly and maintenance of individually damaged external electrodes 1, improving maintenance efficiency by eliminating the need for complete disassembly. The rotation of the threaded sleeve 33 will also drive the support plate 38 to rotate, which in turn will drive the scraper 39 to move. The scraper 39 will then move the external... The surface of electrode 1 is cleaned to remove adsorbed substances, ensuring the cleanliness of the outer electrode 1. Water pumped by the micro water pump 30 flows through the connecting channel 37 into the diversion channel 40, and then through the nozzle 41, the water is directed towards one side of the outer electrode 1 surface, further ensuring its cleanliness. This allows for uniform and stable electrode discharge, eliminating the risk of arcing and breaking down the glass medium. It also improves the water-cooled heat exchange effect of the outer electrode 1, reduces ozone decomposition at high temperatures, increases ozone production efficiency, reduces equipment energy consumption, ensures good conductivity between the grounding screw and the metal contact surface, prevents electric field interference caused by potential shifts between electrodes, delays corrosion and aging of the stainless steel electrode, and reduces maintenance costs associated with downtime and electrode replacement. This is especially important when the micro water pump 30 is pumping liquid media.The coolant inside the insulating housing 10 flows into the water tank 44. Before the coolant enters the installation box 29, the filter plate 46 filters the fluid to achieve the purpose of cleaning the rinsing liquid. Later, when removing impurities filtered and intercepted on the surface of the filter plate 46, the waterproof electric push rod 49 is operated to adjust the position of the cleaning plate 50. As the cleaning plate 50 moves, it removes the impurities adsorbed on the surface of the filter plate 46. The removed impurities fall to the outside through the drain trough 45 and are stored in the storage tank 22. Alternatively, the micro water pump 30 can be started separately to pump and transfer the coolant. This repeated process filters the coolant, reducing the amount of floating matter in the coolant and its impact on ozone production. The filter plate 46 is removable and can be maintained periodically. When too many impurities adsorbed on the filter plate 46 affect the filtration effect, the filter plate 46 can be removed and replaced.
