Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of ozone generating devices, and particularly relates to a discharge unit for ozone generation and an ozone generator. Background Art
[0002] Ozone has functions such as sterilization, decolorization, oxidation, and deodorization. At the same time, the remaining tail gas after the ozone reaction decomposes into oxygen, having advantages such as no residue and no secondary pollution, and is known as a green, highly efficient, broad-spectrum bactericide and strong oxidant. Large-scale ozone generators are widely used in fields such as drinking water treatment, municipal sewage treatment, industrial wastewater treatment, flue gas denitrification, pulp bleaching, and fine chemical oxidation. The structure and connection method of the high-voltage electrode in the discharge chamber of an ozone generator directly affect the ozone generation efficiency and the stability and reliability of the equipment operation, and are one of the key components of a large-scale ozone generator.
[0003] Such as Figures 1 to 6 In the prior art shown, the generating chamber of a large-scale ozone generator is composed of a large number of discharge units connected in parallel. In each discharge unit, a hard connection method is used between the high-voltage electrode 1 and the discharge device. As Figure 1 shown, the assembly accuracy between the high-voltage electrode 1 and the discharge device will affect the uniformity of the discharge gap I5. If the discharge gap I5 is not uniform, as Figure 2 shown, it will cause problems of low discharge efficiency and high ozone power consumption. When multiple discharge units are connected in parallel, small errors in the assembly between the high-voltage electrode 1 and the discharge device in each discharge unit will be accumulated and amplified, further increasing the assembly accuracy difference between the high-voltage electrode 1 and the discharge device, making the uniformity of the discharge gap I5 worse, resulting in lower discharge efficiency and higher ozone power consumption; in addition, in the prior art, multiple discharge units are connected in parallel by a hard connection method, that is, the high-voltage electrode 1 and the high-voltage electrode 1 are connected by a hard connection piece 4. The structure of the parallel connection piece 4 is as Figures 3 to 6 shown. If there are errors in the assembly accuracy between the high-voltage electrode 1 and the discharge device in each discharge unit, the error will increase after multiple discharge units are connected in parallel. The hard connection method between the high-voltage electrode 1 and the high-voltage electrode 1 and between the high-voltage electrode 1 and the discharge device will cause large-area breakage of the glass dielectric discharge tube 3 during assembly, transportation, and operation.

In addition, the present invention provides examples of various specific processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.
[0024] As Figures 7 to 12 shown, the present application provides a discharge unit for ozone generation. When the high-voltage electrode 100 is connected to the discharge device, it will not generate mechanical stress on the glass dielectric discharge tube 300 of the discharge device, thereby improving the uniformity of the discharge gap 500 of the discharge device, and further improving the ozone discharge efficiency. The discharge unit for ozone generation includes a discharge device and a high-voltage electrode 100. Specifically: The discharge device is used to electrolyze oxygen to generate ozone gas. The discharge device includes: An inner electrode 200; A discharge tube 300, and the discharge tube 300 is sleeved outside the inner electrode 200; An outer electrode 400. The outer electrode 400 is tubular, the outer electrode 400 is sleeved outside the discharge tube 300, and an annular discharge gap 500 is formed between the outer electrode 400 and the discharge tube 300. The uniform annular discharge gap 500 improves the ozone discharge efficiency and reduces the power consumption for ozone generation.
[0025] The high-voltage electrode 100 is used to conduct electricity to the discharge device. The high-voltage electrode 100 includes: A connecting rod 101. One end of the connecting rod 101 is connected with a flexible connection structure. The connecting rod 101 is used for conducting electricity and installing the flexible connection mechanism and the connecting wire 105; A flexible connection mechanism. One end of the flexible connection mechanism is connected with the connecting rod 101, and the other end of the flexible connection mechanism is connected with the inner electrode 200; A connecting wire 105. The connecting wire 105 is connected to the connecting rod 101, and the connecting wire 105 is used to connect to the ozone generation power supply.
[0026] The connecting rod 101, the connecting wire 105, and the flexible connection mechanism are all made of conductive materials. 316L stainless steel material can be used. The 316L stainless steel material has good processing performance and corrosion resistance, which is convenient for processing the connecting rod 101, the connecting wire 105, and the flexible connection mechanism into the required structures and can improve the service life.
[0027] The connection method of the connecting wire 105 enables the flexible adjustment of the position of the high-voltage electrode 100; and the connecting wire 105 can also connect multiple sets of discharge units in parallel. Compared with the connection method using a hard connecting piece in the prior art as shown in Figures 1 to 6 , it reduces the high dependence on the processing accuracy of the discharge device and the high-voltage electrode 100, reduces the difficulty of assembly and manufacturing, and improves the ozone discharge efficiency.
[0028] During use, one end of the flexible connection mechanism is connected to the inner electrode 200 of the discharge device, and the other end of the flexible connection mechanism is connected to the connecting rod 101. If multiple sets of high-voltage electrodes 100 need to work together, the connecting rods 101 of multiple sets of high-voltage electrodes 100 can be connected together using the connecting wire 105; connect the high-voltage electrode 100 to the inner electrode 200 of the discharge device through the flexible connection mechanism, and then energize the high-voltage electrode 100, and the oxygen introduced into the discharge gap 500 can be electrolyzed to generate ozone gas.
[0029] As shown in Figure 7 , the connecting rod 101 is a tubular structure. The tubular connecting rod 101 can solve the skin effect caused by the medium and high-frequency discharge current, reduce the heating of the high-voltage electrode 100 caused by the skin effect, and thus reduce the power loss.
[0030] The tubular structure includes a main body section 1011 and a reduced-diameter section 1012. The outer diameter of the reduced-diameter section 1012 is smaller than the outer diameter of the main body section 1011. The main body section 1011 is used to connect the connecting wire 105, and the reduced-diameter section 1012 is used to connect the flexible connection mechanism.
[0031] In this embodiment, the main body section 1011 is a circular tube section, and the reduced-diameter section 1012 is a flat section. The wall thickness of the main body section 1011 is greater than the wall thickness of the reduced-diameter section 1012. The thinner wall of the reduced-diameter section 1012 is convenient for connecting with the flexible connection mechanism. The tubular structure is respectively set as the main body section 1011 and the reduced-diameter section 1012, which is convenient for distinguishing the two ends of the connecting rod 101 during processing and improves the processing efficiency. The outer diameter of the reduced-diameter section 1012 is smaller than the outer diameter of the main body section 1011. Such a setting can not only reduce the consumption of materials for manufacturing the connecting rod 101 and reduce the production cost, but also be convenient for subsequent connection with the flexible connection mechanism.
[0032] The flexible connection mechanism includes a flexible connection main body member 102 with a mesh sleeve structure. One end of the flexible connection main body member 102 is connected to the inner electrode 200, and the other end of the flexible connection main body member 102 is connected to the connecting rod 101.
[0033] The flexible connection main body member 102 is a mesh sleeve structure woven by filamentous wires. The flexible connection main body member 102 with a mesh sleeve structure can not only be conveniently connected and fixed to the inner electrode 200 of the discharge device, but also ensure the current-carrying capacity of the discharge current.
[0034] As shown inFigure 8 As shown in the figure, the flexible connection mechanism further includes a first fixing member 103. The flexible connection main body 102 includes a discharge connection portion 1021 connected to the inner electrode 200 and a bundle portion 1022 connected to the connecting rod 101. The discharge connection portion 1021 is sleeved between the inner electrode 200 and the discharge tube 300. The bundle portion 1022 integrates the flexible connection main body 102 with a net sleeve structure into a bundle. The bundle portion 1022 is inserted into the reduced diameter section 1012 of the connecting rod 101. A first fixing hole is further provided on the reduced diameter section 1012 of the connecting rod 101. A first fixing member 103 is connected in the first fixing hole. The first fixing member 103 is used to connect and fix the bundle portion 1022 and the reduced diameter section 1012.
[0035] In this application, the first fixing member 103 includes a first compression screw. The first compression screw is threadedly connected in the first fixing hole, and the height of the first compression screw is less than the outer diameter of the main body section 1011. This is because after the first compression screw compresses the flexible connection main body 102, the high-voltage insulation distance can be guaranteed, and at the same time, the problem of tip discharge caused by the end of the first compression screw can be effectively avoided.
[0036] During installation, one end of the net sleeve structure is integrated into a bundle and inserted into the cavity of the reduced diameter section 1012 of the connecting rod 101. The first compression screw is threadedly connected in the first fixing hole (not shown in the figure) on the connecting rod 101 to fix the flexible connection main body 102 on the connecting rod 101. This installation method is simple in assembly, and multiple disassembly does not affect the reuse of the connecting rod 101 and the flexible connection main body 102.
[0037] As Figure 9 shown in the figure, the flexible connection mechanism further includes a clamping hoop 104. The flexible connection main body 102 includes a discharge connection portion 1021 connected to the inner electrode 200 and a socket portion 1023 connected to the connecting rod 101. The discharge connection portion 1021 is sleeved between the inner electrode 200 and the discharge tube 300. The socket portion 1023 is sleeved on the reduced diameter section 1012 of the connecting rod 101. The clamping hoop 104 is sleeved at the connection between the socket portion 1023 and the reduced diameter section 1012 of the connecting rod 101.
[0038] During installation, the socket portion 1023 of the flexible connection mechanism is directly sleeved on the reduced diameter section 1012 of the connecting rod 101, and then the clamping hoop 104 is installed outside the flexible connection main body 102 to achieve fixation. This installation method does not require opening a first fixing hole on the reduced diameter section 1012 of the connecting rod 101, which can reduce the pre-manufacturing cost and shorten the manufacturing time; this method does not affect the reuse of the connecting rod 101 and the flexible connection main body 102 after multiple disassembly.
[0039] As Figure 10As shown, the soft connection main body 102 includes a discharge connection part 1021 connected to the inner electrode 200 and a bundle part 1022 connected to the connecting rod 101, the discharge connection part 1021 is sleeved between the inner electrode 200 and the discharge tube 300, the bundle part 1022 is inserted into the shrinkage section 1012 of the connecting rod 101, and the shrinkage section 1012 and the bundle part 1022 are pressed by cold pressing.
[0040] During installation, one end of the mesh structure is integrated into a bundle and inserted into the cavity of the necking section 1012 of the connecting rod 101, and the necking section 1012 and the soft connecting main body 102 are cold pressed to achieve the connection between the connecting rod 101 and the soft connecting main body 102. This installation method also has the advantage of simple assembly, but the connecting rod 101 cannot be used again after being fixed in this way.
[0041] The above three methods can be selected according to production requirements, thereby ensuring low cost and high efficiency in connecting the high voltage electrode 100 with the discharge device, thereby completing the production of the discharge unit.
[0042] like Figures 8 to 11 As shown, a through hole is radially opened on the main section 1011 of the connecting rod 101, and the connecting line 105 is passed through the through hole. A second fixing member 106 is connected to the cavity of the main section 1011 of the connecting rod 101 away from one end of the soft connecting main body 102, and the second fixing member 106 is used to fix the connecting line 105 and the connecting rod 101.
[0043] In the present application, the second fixing member 106 includes a second clamping screw, and a thread matching the second clamping screw is provided in a through hole radially opened on the main body section 1011, and the second clamping screw is threadedly connected in the through hole. The through hole is arranged within the travel range of the second clamping screw, so that the second clamping screw can fix the connecting wire 105 and the connecting rod 101.
[0044] During installation, after the connecting wire 105 is passed through the through hole and the position is selected, the second clamping screw is screwed into the cavity of the main section 1011 of the connecting rod 101. When the second clamping screw is loosened from the connecting rod 101, the connecting wire 105 has a certain range of freedom of movement and can flexibly adjust the position.
[0045] The present application also provides an ozone generator, including an ozone generating chamber, wherein a plurality of ozone generating discharge units as described above are arranged in the ozone generating chamber, such as Figure 11 As shown, multiple groups of ozone generating discharge units are connected in parallel via connecting wires 105, such as Figure 12 As shown, the connecting wires 105 are bundled and connected to the power supply, and the multiple groups of ozone generating discharge units are arranged in a honeycomb shape. The multiple groups of discharge units arranged in a honeycomb shape are arranged flexibly, which reduces the difficulty of assembly and manufacturing, improves the ozone discharge efficiency, and is conducive to the production and manufacturing of large ozone generators.
[0046] The discharge unit for ozone generation and the ozone generator provided in this application can ensure the uniformity of the discharge gap 500 of the discharge device, reduce the processing difficulty of the process, improve the ozone discharge efficiency, and facilitate production, manufacturing, transportation and use.
