[0002] The ozone generator for sewage treatment is a highly efficient equipment specially used for sewage treatment. It converts oxygen into ozone with strong oxidizing properties through technologies such as high-voltage discharge or ultraviolet irradiation. In the sewage treatment process, the ozone generated by the ozone generator is introduced into the sewage, which can quickly decompose organic matter in the sewage, kill bacteria and viruses, remove odor and color, etc. The strong oxidizing property of ozone destroys the molecular structure of organic matter and converts it into harmless substances, thereby significantly improving the water quality of sewage. This generator has the advantages of simple operation, rapid response, significant effect and no secondary pollution. It has become an important and effective treatment method in the field of modern sewage treatment, and plays an important role in protecting water resources and environmental quality.

[0003] Ozone generators for sewage treatment usually use compressed air to pass into a discharge chamber to produce ozone. Existing air source ozone generators usually only have a heat dissipation system outside the discharge chamber. Since the air is compressed, the temperature will rise. The heat dissipation effect at the center of the discharge chamber is poor, which will affect the ozone generation efficiency. Therefore, it is necessary to invent an ozone generator that can cool the air in advance before entering the discharge chamber. Utility Model Content

[0027] Example 1

[0028] See also Figures 1 to 8 An ozone generator for sewage treatment comprises a shell 1, a discharge chamber 2, an air compressor 4 and a cooling chamber 7, wherein the discharge chamber 2 is installed in the shell 1, a first water cooling system 3 is installed between the discharge chamber 2 and the shell 1, an array of electrodes 21 is arranged in the discharge chamber 2, and the electrode 21 is installed in the discharge chamber 2 through a bracket, the cooling chamber 7 is connected to the discharge chamber 2 through an air inlet pipe 8, the air compressor 4 is connected to the cooling chamber 7, an end of the discharge chamber 2 away from the air inlet pipe 8 is provided with an air outlet pipe 9, and an inspection door 102 is provided on the side of the shell 1 close to the air outlet pipe 9.

[0029] like Figure 2 As shown, the air intake pipe 8 is wrapped with a heat-insulating layer 81 .

[0030] like Figure 2 and Figure 7 As shown, the cooling chamber 7 is provided with a second water cooling system 71, the first water cooling system 3 and the second water cooling system 71 can be connected by a conduit, and the heat dissipation of the discharge chamber 2 and the cooling of the cooling chamber 7 can be completed by using a set of water cooling equipment, and the first water cooling system 3 and the second water cooling system 71 can be filled with water or a low-temperature medium.

[0031] like Figure 2 , Figure 3 and Figure 8As shown, the air intake end of the air compressor 4 is connected to an air volume valve 41, and the air volume valve 41 includes a shell 411, a blade 412 and a rotating rod 413. One end of the blade 412 is rotatably connected to the shell 411 and the other end is connected to the rotating rod 413. The blades 412 are arranged in an array on the shell 411, and two adjacent rotating rods 413 are connected by a connecting rod 414. A connecting rod 414 can be connected to the uppermost or lowermost rotating rod 413, and the connecting rod 414 can be driven by a cylinder. The cylinder can realize remote control of the air intake volume by connecting to a controller.

[0032] like Figure 1 , Figure 4 and Figure 7 As shown, the air inlet end of the air compressor 4 is connected to a filter box 5 and a drying box 6.

[0033] like Figure 1 and Figure 7 As shown, a base 101 is connected to the bottom of the housing 1 .

[0034] like Figure 1 , Figure 4 and Figure 7 As shown, the air outlet pipe 9 is detachably connected to the inspection door 102 .

[0035] Principle and operation process

[0036] The utility model controls each component through a controller. As the pressure of the compressed air increases, its temperature will rise. The heat dissipation inside the discharge chamber 2 is only carried out by the external first water cooling system 3. The heat dissipation effect near the center is poor. By setting up a cooling system, the air can be cooled before the compressed air enters the discharge chamber 2. This not only reduces the heat dissipation pressure of the first water cooling system 3, but also allows the compressed air entering the discharge chamber 2 to take away part of the heat in the discharge chamber 2 during the gas transportation process, reducing the heat dissipation pressure of the first water cooling system 3 and improving the reaction efficiency. An insulation layer 81 is set outside the air inlet pipe 8 to keep the cooled compressed air warm, reduce heat exchange, and prevent the compressed air from heating up again. An air volume valve 41 is arranged at the air inlet end of the air compressor 4, which can control the air flow entering the discharge chamber 2. The controller can also control the cylinder to push the blade 412 of the air volume valve 41 to rotate, which can realize remote operation, reduce the contact between the operator and the device, and ensure the safety of the operator. At the same time, the air intake volume can be adjusted according to different usage requirements to save energy; the air outlet pipe 9 can be detachably connected to the inspection door 102. During inspection and maintenance, it can be disassembled, and the inspection door 102 can be opened to maintain or inspect the inside of the discharge chamber 2. After disassembly, the air outlet pipe 9 is connected to the ozone delivery pipeline, and there is no need to disassemble it again, which simplifies the repair and maintenance process.

[0037] When in use, the demand for ozone is determined according to the content of pollutants in the sewage. According to the demand, the air volume valve 41 is controlled and adjusted, and the air compressor 4 is turned on. The compressed air passes through the cooling chamber 7 and then enters the discharge chamber 2 through the air inlet pipe 8. Ionization is performed in the discharge chamber 2 to generate ozone, and the ozone enters the delivery pipeline through the air outlet pipe 9.

[0038] Although the specific implementation methods of the utility model are described above in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. On the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
