Description

Technical Field

[0001] This utility model relates to the field of ozone generator manufacturing technology, specifically to a micro discharge unit design for an ultra-high concentration ozone generator, which adopts a micro-diameter discharge unit structure. Background Technology

[0002] The tubular discharge unit of existing large ozone generators consists of a concentric circular structure of an outer electrode, a dielectric tube, and an inner electrode. The outer electrode is welded to a separating metal plate that isolates the gas chambers and cooling water chambers at both ends. The outer electrode serves as the negative electrode, and the inner electrode serves as the positive electrode. The gaps between the outer electrode and the dielectric tube (outer gap) and between the dielectric tube and the inner electrode (inner gap) constitute the discharge gaps for ozone generation.

[0003] Existing ozone generators include a housing and a tubular discharge unit. The tubular discharge unit includes an inner electrode, a dielectric tube, and an outer electrode that are nested together. A first fixing plate and a second fixing plate are respectively provided at both ends of the housing. A cooling chamber is located between the first fixing plate and the second fixing plate. A first end cap is provided on the outer side of the first fixing plate, and a second end cap is provided on the outer side of the second fixing plate. An air inlet chamber is located between the first end cap and the first fixing plate, and an air outlet chamber is located between the second end cap and the second fixing plate. The first fixing plate has a first mounting hole for the discharge unit, and the second fixing plate has a second mounting hole for the discharge unit. The discharge unit passes through the first mounting hole and the second mounting hole. The outer electrode is sealed to the first and second mounting holes of the discharge unit by welding.

[0004] Due to limitations in welding processes and pipe diameter tolerances, the diameter of the tubular discharge unit in ozone generators cannot be made very small; they are all large diameters, with the smallest diameter currently between 10 and 20 mm. The diameters of the dielectric tube and inner electrode, which are nested in concentric circles, are smaller than the diameter of the outer electrode, ranging from 8 to 18 mm. The main gap between the inner and outer discharge gaps is between 0.3 and 1 mm.

[0005] Based on the above discharge unit structure, the world's optimal economic operating ozone concentration for existing large-scale ozone generators is 150 mg / L (approximately 10 wt%). Each kilogram of ozone requires 10 kilograms of oxygen (approximately 10 yuan), consumes 8 kWh of electricity (approximately 8 yuan), and has a production cost of approximately 18 yuan per kilogram of ozone (10 wt%). This structural type has been the mainstream ozone generator structure for fifty years, without any significant technological advancements.

[0006] Ozone, as a strong oxidant, is currently one of the mainstream technologies in drinking water pretreatment, advanced industrial wastewater treatment, atmospheric denitrification, and semiconductor chip manufacturing, and is widely used. Therefore, increasing ozone concentration and reducing ozone production costs have become core issues of concern in the industry. However, the ozone generators constructed using the aforementioned discharge unit diameter and discharge gap size have been in use and refined for fifty years, yet they still cannot solve these problems.

[0007] It is well known that the diameter and discharge gap of a small-diameter discharge unit (outer electrode, dielectric tube, and inner electrode) can significantly increase the concentration of ozone produced and reduce the cost of ozone production. For example, utility model patent document CN1013571B discloses an ozone production device whose outer electrode has an inner diameter of only 5 to 10 millimeters, and whose inner electrode can be composed of metal wires with a diameter of 0.5 to 3 millimeters. The inner electrode can withstand a strong electric field strength; that is, a small radius of curvature generates a large electric field strength. A larger electric field strength can produce a higher ozone concentration, therefore, a small-diameter discharge unit can produce a higher concentration of ozone. However, to date, no ozone generator with a small-diameter discharge unit has appeared on the market. The main reason is:

[0008] 1. The water vapor separation and sealing problem of the external electrode in the discharge unit with a small diameter (less than 5 mm): Since the external electrode is too thin to be welded using current common welding technology, no better solution to the sealing problem has been found so far.

[0009] 2. The external electrode of the micro-diameter discharge unit is too thin and soft and is easy to bend. It cannot be quickly and efficiently passed through the cooling water cavity with a length of more than one meter and fixed to the corresponding position of the air cavity at the other end. At present, there is no efficient production process, which makes it impossible to carry out manufacturing efficiently.

[0010] 3. The number of ozone discharge units with tiny diameters has increased dramatically. For example, the number of discharge units required to generate 100 kilograms of ozone has increased from 6,000 in existing equipment to 70,000 now. The workload of installing external electrodes through tubes has increased significantly, making it impossible to manufacture the equipment.

[0011] Therefore, there is an urgent need in this technical field for an ozone generator that uses a sealing method for the external electrode of a small-diameter discharge unit and a corresponding high-efficiency external electrode tube, which can efficiently enable the rapid mass production of ozone generators with small-diameter discharge units, thereby increasing the ozone concentration generated while reducing the ozone production cost. Utility Model Content

[0012] The technical problem to be solved by this utility model is to provide an ozone generator that adopts a sealing method for the external electrode of a small-diameter discharge unit and a corresponding high-efficiency external electrode tube, which enables the rapid mass production of ozone generators with small-diameter discharge units, thereby increasing the ozone concentration generated while reducing the ozone production cost.

[0013] This utility model is implemented as follows: An ozone generator includes a housing and a tubular discharge unit. The tubular discharge unit includes an inner electrode, a dielectric tube, and an outer electrode mounted in a nested manner. The gap between the inner electrode and the dielectric tube is the inner gap, and the gap between the dielectric tube and the outer electrode is the outer gap. A first fixing plate and a second fixing plate are respectively provided at both ends of the housing. A cooling cavity is formed between the first fixing plate and the second fixing plate. A first end cap is provided on the outer side of the first fixing plate, and a second end cap is provided on the outer side of the second fixing plate. A first end cap is provided between the first fixing plate and the first fixing plate. The second air chamber is located between the second end cap and the second fixing plate. The first fixing plate has a first mounting hole for the discharge unit, and the second fixing plate has a second mounting hole for the discharge unit. The tubular discharge unit passes through the first mounting hole and the second mounting hole. The outer diameter of the outer electrode is less than or equal to 4.8 mm. The outer electrode is fitted with a first sealing ring and a second sealing ring. The first sealing ring seals the gap between the first mounting hole of the discharge unit and the outer electrode, and the second sealing ring seals the gap between the second mounting hole of the discharge unit and the outer electrode.

[0014] The second fixing plate includes an auxiliary fixing plate and an auxiliary fixing plate positioning hole. The auxiliary fixing plate matches the auxiliary fixing plate positioning hole and is nested in the auxiliary fixing plate positioning hole. The second mounting hole of the discharge unit is provided on the auxiliary fixing plate. The auxiliary fixing plate has a third sealing ring that seals the gap between the auxiliary fixing plate positioning hole and the auxiliary fixing plate.

[0015] The ozone generator further includes a first sealing plate and a second sealing plate, which are located on the outside of the first fixed plate and the second fixed plate, respectively. The first sealing plate has a first sliding hole, and the second sealing plate has a second sliding hole. The external electrode also passes through the first sliding hole and the second sliding hole. The first sealing ring is located between the first sealing plate and the first fixed plate. The first sealing plate is locked to the first fixed plate and presses the first sealing ring. The second sealing ring is located between the second sealing plate and the auxiliary fixed plate. The second sealing plate is locked to the auxiliary fixed plate and presses the second sealing ring.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. A simple yet ingenious structure (dual-positioning assisted sliding sealing tube) solves the problem of the inability to significantly increase ozone concentration in ozone generators, a problem that has persisted for fifty years. Through the innovative dual-positioning assisted sliding sealing tube process, a discharge unit with a tiny diameter (millimeter level) has been successfully applied, overcoming the manufacturing obstacles and process difficulties of mass-producing (tens of kilograms or more) ultra-high concentration (above 18 wt%) ozone generators. This results in a significant increase in the ozone concentration of the ozone generator, which will have a huge impact on the innovation, improvement, and efficiency enhancement of the long-standing difficult-to-degrade industrial wastewater treatment process. It provides key equipment support for the low-cost, high-efficiency, and low-concentration discharge of difficult-to-degrade wastewater.

[0018] 2. Compared with ozone generators in the background technology, ozone generators with small diameter discharge units produce significantly more ozone per unit discharge area while producing the same ozone concentration, and the volume of ozone generators producing the same ozone output is significantly reduced.

[0019] 3. Using a small-diameter discharge unit can significantly increase ozone concentration while greatly reducing the power consumption for ozone generation, thus significantly reducing the cost of ozone generation (gas consumption + power consumption).

[0020] 4. The traditional method of sealing the external electrode by welding has been changed to sealing with a sealing ring. The sealing method is more convenient and easier to install the discharge unit, reducing the amount of installation work, shortening the manufacturing time and equipment costs.

[0021] 5. The external electrode is sealed with an O-ring, which facilitates removal and replacement when the external electrode is damaged and needs to be replaced, simplifies maintenance work and reduces labor costs, and shortens downtime required for maintenance. Multiple O-rings and sealing plates can also be used to enhance the sealing effect and improve the safety and reliability of the ozone equipment.

[0022] 6. The ozone generator uses a discharge unit with a small diameter. The number of discharge units is large and the outer electrode is thin. With the cooperation of the auxiliary fixing plate, the outer electrode passes through the two fixing plates on a large scale, quickly and accurately, which improves the production efficiency of the ozone generator.

[0037] This utility model patent proposes an ozone generator that uses a sealing method for the external electrode of a small-diameter discharge unit and a corresponding high-efficiency external electrode tube, which enables rapid mass production of ozone generators with small-diameter discharge units, increasing the ozone concentration while reducing ozone production costs.

[0038] For example, an ozone generator (10 kg / h) proposed according to this utility model patent can increase the optimal economic operating ozone concentration of traditional ozone generators to over 270 mg / L, reducing ozone production costs by over 20%; the maximum ozone concentration can be increased to over 380 mg / L, reducing ozone production costs by over 40%. This significantly reduces the investment and operating costs of industrial wastewater and atmospheric denitrification projects, and is of great significance to improving my country's environmental protection efforts.

[0039] The technical solution of this utility model patent is described in detail below.

[0040] See Figures 1 to 4 The first embodiment of this utility model.

[0041] An ozone generator includes a housing 1 and a tubular discharge unit 2. The tubular discharge unit 2 includes an inner electrode 21, a dielectric tube 22, and an outer electrode 23 mounted in a nested manner. The gap between the inner electrode 21 and the dielectric tube 22 is the inner gap, and the gap between the dielectric tube 22 and the outer electrode 23 is the outer gap. A first fixing plate 11 and a second fixing plate 12 are respectively provided at both ends of the housing 1. A cooling chamber 19 is formed between the first fixing plate 11 and the second fixing plate 12. A first end cap 17 is provided on the outer side of the first fixing plate 11, and a second end cap 18 is provided on the outer side of the second fixing plate 12. A first gas chamber is formed between the first end cap 17 and the first fixing plate 11. 110, a second air chamber 111 is formed between the second end cap 18 and the second fixing plate 12. The first fixing plate 11 has a first mounting hole 13 for the discharge unit, and the second fixing plate 12 has a second mounting hole 15 for the discharge unit. The tubular discharge unit 2 passes through the first mounting hole 13 and the second mounting hole 15 for the discharge unit. The outer diameter of the outer electrode 23 is less than or equal to 4.8 mm. The outer electrode 23 is fitted with a first sealing ring 3 and a second sealing ring 4. The first sealing ring 3 seals the gap between the first mounting hole 13 for the discharge unit and the outer electrode 23, and the second sealing ring 4 seals the gap between the second mounting hole 15 for the discharge unit and the outer electrode 23.

[0042] The second fixing plate 12 includes an auxiliary fixing plate 14 and an auxiliary fixing plate positioning hole 16. The auxiliary fixing plate 14 matches the auxiliary fixing plate positioning hole 16 and is nested in the auxiliary fixing plate positioning hole 16. The second mounting hole 15 of the discharge unit is provided on the auxiliary fixing plate 14. The auxiliary fixing plate 14 has a third sealing ring 5, which seals the gap between the auxiliary fixing plate positioning hole 16 and the auxiliary fixing plate 14.

[0043] The ozone generator also includes a first sealing plate 6 and a second sealing plate 7, which are located on the outside of the first fixing plate 11 and the second fixing plate 12, respectively. The first sealing plate 6 has a first sliding hole, and the second sealing plate 7 has a second sliding hole. The external electrode 23 also passes through the first sliding hole and the second sliding hole. The first sealing ring 3 is located between the first sealing plate 6 and the first fixing plate 11. The first sealing plate 6 is locked to the first fixing plate 11 and presses the first sealing ring 3. The second sealing ring 4 is located between the second sealing plate 7 and the auxiliary fixing plate 14. The second sealing plate 7 is locked to the auxiliary fixing plate 14 and presses the second sealing ring 4.

[0044] The first air chamber 110 is an air inlet chamber, and the second air chamber 111 is an air outlet chamber; or the first air chamber 110 is an air outlet chamber, and the second air chamber 111 is an air inlet chamber. The second sealing pressure plate 7 is matched with the auxiliary fixing plate 14 or with the second fixing plate 12. The first fixing plate 11 and the second fixing plate 12 are respectively and sealingly welded to both ends of the housing 1.

[0045] Because the first sealing ring 3 seals the gap between the first mounting hole 13 of the discharge unit and the outer electrode 23, and the second sealing ring 4 seals the gap between the second mounting hole 15 of the discharge unit and the outer electrode 23, the coolant in the cooling chamber 19 cannot flow into the air inlet and outlet chambers. The cooling chamber 19 has a coolant inlet and a coolant outlet for heat dissipation of the tubular discharge unit 2. O-rings are preferred for easy assembly and disassembly. In the tubular discharge unit 2, the inner electrode 21, the dielectric tube 22, and the outer electrode 23 are installed in parallel and nested together. The diameters of the first mounting hole 13 and the second mounting hole 15 of the discharge unit are slightly larger than the outer diameter of the outer electrode 23.

[0046] Due to the large number of tiny-diameter discharge units and the significant distance between the first fixing plate 11 and the second fixing plate 12, it is difficult to allow the external electrode 23 to pass directly through the first fixing plate 11 and the second fixing plate 12, making it impossible to quickly and accurately pass through the tube. This invention uses an auxiliary fixing plate 14, which helps the external electrode 23 to quickly and accurately pass through the first fixing plate 11 and the second fixing plate 12. The sealing pressure plate strengthens the positional stability of the sealing ring and improves the sealing performance of the external electrode 23.

[0047] Furthermore, the outer diameter of the outer electrode 23 ranges from 0.3 mm to 4.8 mm.

[0048] This invention uses a discharge unit with a small diameter and replaces the traditional welding method with a sealing ring to seal the external electrode, thereby increasing the concentration of ozone generated.

[0049] Furthermore, the inner gap serves as the discharge gas gap 24 for ozone production, while the outer gap is sealed or blocked.

[0050] Furthermore, the second sealing plate 7 simultaneously presses against the third sealing ring 5.

[0051] This facilitates the sealing between the auxiliary fixing plate 14 and the second fixing plate 12.

[0052] In one embodiment of the present invention, the first fixing plate 11 is provided with a first sealing ring mounting groove at the first mounting hole 13 of the discharge unit, and the first sealing ring 3 is located in the first sealing ring mounting groove; the auxiliary fixing plate 14 is provided with a second sealing ring mounting groove at the second mounting hole 15 of the discharge unit, and the second sealing ring 4 is located in the second sealing ring mounting groove.

[0053] In another embodiment of the present invention, the inner side of the first sealing pressure plate 6 is provided with a first sealing ring mounting groove at the first sliding hole, and the first sealing ring 3 is located in the first sealing ring mounting groove. The inner side of the second sealing pressure plate 7 is provided with a second sealing ring mounting groove at the second sliding hole, and the second sealing ring 4 is located in the second sealing ring mounting groove.

[0054] Both the first sealing ring mounting groove and the second sealing ring mounting groove are annular grooves.

[0055] The first annular groove is coaxial with the first mounting hole 13 of the discharge unit. The first elastic O-ring is embedded in the first annular groove and, after being squeezed by the first sealing plate 6, seals the gap between the outer electrode 23 and the first mounting hole 13 of the discharge unit. The diameter of the first sliding hole of the first sealing plate 6 is larger than the outer diameter of the outer electrode 23, but smaller than the diameter of the first annular groove and the inner diameter of the first sealing ring 3.

[0056] Furthermore, the second fixing plate 12 is provided with a third sealing ring mounting groove at the auxiliary fixing plate positioning hole 16, and the third sealing ring 5 is located in the third sealing ring mounting groove.

[0057] Alternatively, a wedge-shaped groove is provided on the outer edge of the auxiliary fixing plate 14, and the third sealing ring 5 is located in the wedge-shaped groove.

[0058] The sealing effect is better by pressing the third sealing ring 5 located in the wedge groove with the sealing pressure plate.

[0059] Furthermore, the sealing rings of the first sealing ring 3, the second sealing ring 4, and the third sealing ring 5 are made of fluororubber, EPDM, or silicone, and the sealing rings are circular or elliptical in shape, with a cross-sectional shape that is circular, rectangular, or U-shaped.

[0060] Both the first sealing plate 6 and the second sealing plate 7 are flat plates.

[0061] The ozone generator uses a large number of tubular discharge units 2 with a small diameter. The tubular discharge units 2 are thin and, with the cooperation of the auxiliary fixing plate 14, the tubular discharge units 2 can pass through the two fixing plates on a large scale, quickly and accurately.

[0062] Since the cooling chamber 19 is located between the first fixing plate 11 and the second fixing plate 12, and there is a certain distance between the two fixing plates, the traditional method of first fixing the first fixing plate 11 and the second fixing plate 12 to both ends of the cooling chamber 19, and then passing the external electrodes 23 one by one through the first fixing plate 11 and the second fixing plate 12, is inefficient and prone to damage during the installation process. This problem is particularly prominent in large ozone generators, where the tubular discharge unit 2 is thin and has a large span at both ends, making it easy to bend and difficult to pass through the second end.

[0063] This utility model employs an auxiliary fixing plate 14 and an auxiliary fixing plate positioning hole 16. The first fixing plate 11 and the second fixing plate 12 are fixed at both ends of the cooling cavity 19. The auxiliary fixing plate 14 is then attached to the inner side of the first fixing plate 11. The external electrode 23 is passed through the first fixing plate 11 and the auxiliary fixing plate 14 that is tightly attached to the first fixing plate 11, thereby improving the installation efficiency of the external electrode 23. The auxiliary fixing plate 14 is pulled and nested in the auxiliary fixing plate positioning hole 16 of the second fixing plate 12, effectively preventing damage to the tubular discharge unit 2.

[0064] A method for manufacturing an ozone generator, used to manufacture the ozone generator of this embodiment, includes the following steps:

[0065] S1. A first fixing plate 11 is fixedly installed at one end of the housing 1. The first fixing plate 11 has a first mounting hole 13 for the discharge unit.

[0066] S2. The auxiliary fixing plate 14 is attached to the inner side of the first fixing plate 11.

The first mounting hole 13 of the discharge unit is aligned with the second mounting hole 15 of the discharge unit.

The auxiliary fixing plate 14 moves along the external electrodes 23 toward the second fixing plate 12, and at the same time, the external electrodes 23 also move toward the second fixing plate 12. During the process of pulling the auxiliary fixing plate 14, the external electrodes 23 are simultaneously on the first fixing plate 11 and the auxiliary fixing plate 14.

[0070] The auxiliary fixing plate 14 can be pulled by hand, rope, lever or other existing technology; the outer electrode 23 can be pushed by hand, push plate or other tools in the direction outside the first fixing plate 11.

[0072] S6. Place the third sealing ring 5 from the outside of the second fixing plate 12 into the corresponding positioning hole 16 of the auxiliary fixing plate and the outside of the auxiliary fixing plate 14.

[0073] S7. The second sealing ring 4 is placed on the outer electrode 23 from the outside of the second fixing plate 12, and then the second sealing pressure plate 7 is used to press the second sealing ring 4 from the outside of the second fixing plate 12. The second sealing pressure plate 7 is locked to the auxiliary fixing plate 14, and the outer electrode 23 passes through the second sliding hole of the second sealing pressure plate 7.

[0074] S8. The first sealing ring 3 is placed on the outer electrode 23 from the outside of the first fixing plate 11, and then the first sealing pressure plate 6 is used to press the first sealing ring 3 from the outside of the first fixing plate 11. The first sealing pressure plate 6 is locked to the first fixing plate 11, and the outer electrode 23 passes through the first sliding hole of the first sealing pressure plate 6.

[0075] S9. Insert the dielectric tube 22 into the outer electrode 23, and then insert the inner electrode 21 into the dielectric tube 22.

[0076] The gap between the inner electrode 21 and the dielectric tube 22 is the inner gap, and the gap between the dielectric tube 22 and the outer electrode 23 is the outer gap. The outer gap is sealed or blocked, and the inner gap serves as the discharge gas gap 24 for generating ozone.

[0077] Finally, a first end cap 17 and a second end cap 18 are respectively provided at both ends of the housing 1.

[0078] Alternatively, S3 specifically involves: first inserting the dielectric tube into the outer electrode 23, then passing the outer electrode 23 along with the dielectric tube through the first mounting hole 13 and the corresponding second mounting hole 15 of the discharge unit. S9 specifically involves: inserting the inner electrode 21 into the dielectric tube 22; the gap between the inner electrode 21 and the dielectric tube 22 is the inner gap, and the gap between the dielectric tube 22 and the outer electrode 23 is the outer gap; sealing or blocking the outer gap; and using the inner gap as the ozone-generating discharge gap 24; finally, providing a first end cap 17 and a second end cap 18 at both ends of the housing 1.

[0079] The first embodiment of this utility model mainly describes an ozone generator with a connection structure of tubular discharge unit 2, first fixing plate 11, second fixing plate 12, and auxiliary fixing disk 14. The description may specify that the number of auxiliary fixing disks 14 is one, or it may be a general description where the number of auxiliary fixing disks 14 is not limited.

[0080] See Figure 5 and Figure 6 The second embodiment of this utility model.

[0081] Furthermore, there are multiple auxiliary fixing plates 14, each of which has multiple second mounting holes 15 for the discharge unit. The number of positioning holes 16 for the auxiliary fixing plates is equal to the number of auxiliary fixing plates 14. The first fixing plate 11 has multiple sets of mounting hole areas, each set of mounting hole areas having multiple first mounting holes 13 for the discharge unit. The number of mounting hole areas is equal to the number of auxiliary fixing plates 14. In the corresponding mounting hole areas and auxiliary fixing plates 14, the number of first mounting holes 13 for the discharge unit is equal to the number of second mounting holes 15 for the discharge unit.

[0083] Furthermore, there are multiple second sealing pressure plates 7, each second sealing pressure plate 7 covering one or more of the auxiliary fixing discs 14, and the second sealing pressure plate 7 pressing the corresponding second sealing ring 4 and the third sealing ring 5.

[0084] Preferably, each of the second sealing plates 7 covers one of the auxiliary fixing plates 14.

[0085] The second mounting holes 15 of the discharge units on the auxiliary fixing plate 14 are arranged in a honeycomb pattern, and the positioning holes 16 of the auxiliary fixing plate 12 are also arranged in a honeycomb pattern. A large number of tubular discharge units 2 are grouped using multiple auxiliary fixing plates 14, and then the discharge units are installed onto the housing 1 in an orderly manner according to the groups. Multiple groups of the tubular discharge units 2 are spaced apart inside the housing 1.

[0086] A method for manufacturing an ozone generator, used to manufacture the ozone generator of this embodiment, includes the following steps:

[0087] S1. A first fixing plate 11 is fixedly installed at one end of the housing 1. The first fixing plate 11 has a first mounting hole 13 for the discharge unit. A second fixing plate 12 is fixedly installed at the other end of the housing 1. The second fixing plate 12 has an auxiliary fixing plate positioning hole 16.
