Description

Technical Field

[0001] This utility model relates to the field of ozone generation technology, specifically to an ozone generation device. Background Technology

[0002] An ozone generator is a device used to produce ozone, a strong oxidant widely used in water treatment, air purification, food processing, and medical disinfection. Existing ozone generators primarily use corona discharge or electrochemical methods to produce ozone, but these methods have limitations in terms of stability and efficiency.

[0003] In the corona discharge method, ozone generation depends on high voltage generating corona discharge in oxygen or air. This process is very sensitive to environmental conditions such as temperature, humidity, and gas composition. Temperature changes are particularly significant, causing existing ozone generation devices to experience fluctuations in ozone production and concentration during operation, affecting their stability. On the other hand, although the electrochemical method can generate ozone at lower temperatures and pressures, its conversion efficiency is usually low, and it requires the use of expensive catalysts and electrolytes, which increases operating costs. Therefore, we propose an ozone generation device. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] The ozone generating tank 1, inlet connection port 101, outlet connection port 102, support base 103, temperature sensor 104, first valve body 105, electrode 106, heat exchange tube 107, discharge medium 108, gas equalization ring 109, separator 110, gas equalization slot 111, connecting pipe 112, inlet pipe 2, outlet pipe 3, guide pipe 4, second valve body 401, water inlet pipe 5, third valve body 501, drain pipe 6, and flow detection valve 601 in this application are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0029] Example 1

[0030] Please see Figures 1-5 As shown, this utility model provides a technical solution: an ozone generation device, comprising:

[0031] Ozone generating tank 1, air inlet pipe 2, exhaust pipe 3, water inlet pipe 5, and drain pipe 6;

[0032] The ozone generating tank 1 has an air inlet connection port 101 and an air outlet connection port 102 at the top two ends respectively. A first valve body 105 is provided at one end of the air inlet connection port 101. A support frame 103 is installed at the bottom of the ozone generating tank 1. Temperature sensors 104 are installed at both ends on one side of the ozone generating tank 1. Electrodes 106 are provided at both the upper and lower ends inside the ozone generating tank 1. A discharge medium 108 is provided on one side of the upper electrode 106. A heat exchange tube 107 is embedded inside the electrode 106.

[0033] One end of the intake pipe 2 is connected to the intake connection port 101;

[0034] One end of the exhaust pipe 3 is connected to the exhaust connection port 102;

[0035] Among them, the water inlet pipe 5 is connected to the heat exchange pipe 107, and a third valve body 501 is provided at one end of the water inlet pipe 5;

[0036] One end of the drain pipe 6 is connected to one end of the heat exchange pipe 107, and one end of the drain pipe 6 is equipped with a flow detection valve 601.

[0037] Both ends of the heat exchange tube 107 extend to the outside of the ozone generation tank 1, and both ends of the heat exchange tube 107 are provided with connecting flanges.

[0038] This technical solution: The device power is turned on via an external control cabinet (external control cabinet is existing technology and therefore not shown in the figure). Then, ensure that the first valve 105 is open, the second valve 401 is closed, and the third valve 501 is open. Next, dry gas (such as oxygen or air) enters the ozone generating tank 1 through the inlet pipe 2 and inlet connection port 101. Inside the tank, the gas flows past the electrode 106 and the discharge medium 108, undergoing corona discharge under high voltage to generate ozone. The generated ozone is discharged through the outlet connection port 102 and the exhaust pipe 3 for downstream applications (such as water treatment or disinfection). Simultaneously, cooling water enters the water channel of the heat exchange tube 107 from the water inlet pipe 5 (preferably de-electrode). The water (to prevent scaling) exchanges heat with electrode 106. The flow detection valve 601 adjusts the water flow based on the feedback from temperature sensor 104 to ensure that the temperature of electrode 106 is stable within a low temperature range (e.g., 5-20°C) to prevent ozone decomposition. The water after heat exchange is discharged from drain pipe 6. The external control cabinet integrates a programmable logic controller (PLC) to realize automatic control of temperature, flow, and valve body. Users can set parameters and monitor status through human-machine interface (HMI), which improves the stability and efficiency of ozone production and also achieves low-cost, non-stop maintenance. It is suitable for various industrial scenarios, such as sewage treatment, food processing, and medical disinfection.

[0039] Example 2

[0040] Based on Embodiment 1, this utility model is as follows: Figures 1-5 As shown, a partition plate 110 is provided on the inner side of the heat exchange tube 107, and the heat exchange tube 107 forms a water flow channel and an air flow channel through the partition plate 110. A guide pipe 4 is connected between the air inlet connection port 101 and one end of the heat exchange tube 107. The guide pipe 4 is connected to the air flow channel of the heat exchange tube 107. A second valve body 401 is provided at one end of the guide pipe 4. A connecting pipe 112 is connected to the air flow channel at one end of the heat exchange tube 107. A gas equalization ring 109 is connected to one end of the gas equalization ring 109. A gas equalization slot 111 is provided at one end of the gas equalization ring 109. There are multiple gas equalization slots 111, and the gas equalization slots 111 are inclined.

[0041] This technical solution: When the temperature sensor 104 detects signs of nitrogen oxide accumulation (such as decreased efficiency or abnormal temperature), the control cabinet switches modes: closing the first valve body 105 and the third valve body 501, and opening the second valve body 401. Then, the dry gas enters the airflow channel of the heat exchange tube 107 from the inlet pipe 2 via the connecting pipe 4. The gas absorbs residual heat from the electrode 106 in the airflow channel (or is heated externally, if necessary) and is then introduced into the gas equalization ring 109 via the connecting pipe 112. The heated gas is then ejected from the gas equalization slots 111 of the gas equalization ring 109 at an angle (the upper and lower rings are inclined upwards and downwards respectively), forming a uniform hot airflow that heats the inside of the ozone generation tank 1. Sensor 104 monitors the heating process to ensure that the temperature rises to a level sufficient to decompose nitrogen oxides (e.g., 50-80°C) but does not exceed safety limits. After cleaning is completed (usually a few minutes to tens of minutes, while traditional cleaning time is typically two to three hours), the system switches back to normal mode: the first valve body 105 and the third valve body 501 are opened, and the second valve body 401 is closed. The device continues to produce ozone without the need for cooling. In addition, the heat exchange tube 107 is equipped with a partition plate 110 to form independent water and air channels, achieving countercurrent heat exchange and improving efficiency. The gas distribution ring 109 has multiple inclined gas distribution slots 111 to ensure that hot gas covers the entire cross-section of the tank, avoiding dead corners and improving cleaning uniformity.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
