Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ozone preparation, and particularly to a combined intelligent ozone generator. BACKGROUND

[0002] At present, with the enhancement of environmental awareness and the progress of science and technology, ozone generators have been widely used in air purification, water treatment, medical disinfection and other fields. The traditional ozone generator mainly excites oxygen molecules by high-voltage discharge or ultraviolet radiation, so that the oxygen molecules are decomposed into oxygen atoms, and then combined with the undecomposed oxygen molecules to form ozone.

[0003] In the prior art, when the ozone generator prepares ozone, it usually adopts a high-voltage discharge method to decompose oxygen molecules into oxygen atoms, and the oxygen atoms and oxygen molecules are combined to form ozone. Then, in the process of high-voltage discharge, the electrode generates heat, which causes the temperature of the electrode to rise. When the temperature is too high, the electrode will be damaged, and the ozone formed will be unstable, which affects the preparation efficiency of ozone. SUMMARY

[0004] In order to reduce the influence on the preparation efficiency of ozone, the present application provides a combined intelligent ozone generator.

[0005] The combined intelligent ozone generator provided by the present application adopts the following technical scheme:

[0006] A combined intelligent ozone generator comprises a plurality of ozone preparation units connected by pipelines and switched by valves, each of the ozone preparation units comprising:

[0007] A reaction tube for supporting;

[0008] A first inner tube arranged in the reaction tube and connected with the reaction tube to form a cooling cavity for cooling water to flow;

[0009] A second inner tube arranged in the first inner tube to form a reaction cavity for oxygen decomposition reaction between the first inner tube and the second inner tube;

[0010] An outer electrode arranged on one side of the first inner tube close to the second inner tube;

[0011] An inner electrode arranged on one side of the second inner tube close to the first inner tube to form a discharge area with the outer electrode;

[0012] An oxygen supply pipe arranged on the reaction tube and communicating with the reaction cavity to make oxygen molecules form oxygen atoms after passing through the discharge area;

[0013] A cooling water pipe communicating with the cooling cavity for supplying cold water to cool the outer electrode;

[0014] a first fork tube disposed on the reaction tube, extending into the reaction cavity, and located near one side of the oxygen supply tube, provided with multiple and forming a deceleration zone, the gas inlet end is connected with dry oxygen, and the oxygen supply pressure is less than that of the oxygen supply tube;

[0015] an exhaust tube disposed on the reaction tube for discharging ozone;

[0016] a control module for controlling the energization of the outer electrode and the inner electrode and whether the device supplies oxygen and water.

[0017] By adopting the above technical solution, when ozone needs to be generated, the control module is first started to ensure that all valves are in the correct on-off state to select the appropriate ozone preparation unit for operation; the control module then activates the energization of the outer electrode and the inner electrode to prepare the discharge conditions for the oxygen decomposition reaction; dry oxygen enters the reaction cavity through the oxygen supply tube at a high pressure to ensure that oxygen molecules can pass through the discharge area efficiently. At the same time, the first fork tube also introduces additional dry oxygen at a lower oxygen supply pressure to slow down the flow rate of oxygen, which slows down in the deceleration zone and mixes with the main gas flow, helping to evenly distribute oxygen molecules and improve reaction efficiency.

[0018] The gas inlet tube can be used to supplement additional gas into the reaction cavity at the initial stage or under certain conditions to ensure stable pressure in the reaction cavity or adjust the reaction conditions as needed.

[0019] The cooling water tube supplies cold water into the cooling cavity, effectively reducing the temperature of the outer electrode and its surrounding environment, preventing high temperature caused by discharge from damaging the equipment or affecting the ozone generation efficiency; in the discharge area, the energized outer electrode and inner electrode form a strong electric field, causing the passing oxygen molecules to decompose into oxygen atoms, which then combine into ozone molecules; the ozone generated by the reaction is discharged through the exhaust tube and enters the subsequent processing or application link; the control module continuously monitors various parameters (such as oxygen flow, cooling water temperature, electrode voltage, etc.) and automatically adjusts or issues an alarm according to the preset conditions to ensure stable operation of the equipment and the quality of ozone production.

[0020] The cooling water system effectively reduces the temperature of the electrodes and the reaction cavity, prolonging the service life of the equipment, while also helping to maintain stable reaction conditions and improve ozone generation efficiency; multiple ozone preparation units are connected to each other through pipelines and valves, which can be flexibly switched according to needs, improving the flexibility and scalability of the system; at the same time, through the additional supply of oxygen, the discharge area can be cooled, so that the cooling of the discharge area and the electrodes is carried out simultaneously, improving the cooling effect and efficiency.

[0021] Optionally, the gas outlet axis of the gas outlet end of the first fork tube is perpendicular to the second inner tube.

[0022] By adopting the above technical solution, the vertical gas outlet axis enables the oxygen flowing out of the first cross pipe to enter the reaction cavity in a direction perpendicular to the axis of the second inner pipe (and the reaction cavity). This vertical gas flow helps to more evenly distribute the oxygen in the reaction cavity, reducing dead angles and vortexes of the gas flow in the reaction cavity, thereby improving the contact efficiency of the oxygen and the discharge area and promoting the efficient generation of ozone. The vertical gas outlet mode often accompanies a change in the direction of the gas flow, which helps to slow down the gas flow speed, enabling the oxygen molecules to stay in the reaction cavity for a longer time. The longer residence time means that more oxygen molecules have the opportunity to pass through the discharge area and receive enough energy to decompose into oxygen atoms and further combine into ozone.

[0023] Optionally, a cooling medium flows through the second inner pipe.

[0024] By adopting the above technical solution, the cooling medium, such as cooling water or other suitable fluid, flowing through the second inner pipe can further reduce the temperature around the reaction cavity. This helps to maintain a stable temperature in the discharge area, preventing electrode wear, ozone decomposition or equipment performance degradation caused by high temperature. Enhancing the cooling effect can improve the continuity and stability of ozone generation.

[0025] Improving ozone generation efficiency: the use of cooling medium helps to maintain a suitable temperature range in the reaction cavity, which is crucial for efficient ozone generation. At the appropriate temperature, the decomposition of oxygen molecules and the synthesis of ozone molecules are more rapid and complete, thereby improving the efficiency of ozone generation.

[0026] The cooperation of the second inner pipe and the cooling cavity enables the discharge area to maintain a suitable temperature, reducing the impact of excessive temperature on ozone preparation.

[0027] Optionally, the outer electrode and the inner electrode are both provided with multiple electrodes, which are arranged in a circumferential direction of the first inner pipe. There is a gap between adjacent two inner electrodes or outer electrodes, and a partition is arranged at the gap.

[0028] By adopting the above technical solution, the spaced arrangement of multiple outer electrodes and inner electrodes means that the discharge area is dispersed into multiple small areas. This dispersed discharge mode can increase the contact area of oxygen molecules with the discharge area, thereby improving the efficiency of ozone generation. Each small discharge area can independently excite oxygen molecules to decompose into oxygen atoms and further combine into ozone.

[0029] By precisely controlling the number, position and spacing of the electrodes, the distribution of the electric field in the reaction cavity can be optimized; uniform electric field distribution helps to ensure that oxygen molecules can obtain enough energy for decomposition reaction throughout the reaction cavity, thereby improving the uniformity and stability of ozone generation.

[0030] The presence of the partition not only separates adjacent discharge zones, but also serves as an additional channel for the cooling medium; by skillfully designing the structure and material of the partition, the cooling effect can be further improved, ensuring that the temperature in the reaction chamber remains within a suitable range. This helps to prevent equipment failure or ozone decomposition caused by high temperature.

[0031] The dispersed discharge zones and optimized electric field distribution help to reduce the load and wear of the electrodes. At the same time, the combined action of the partition and the cooling medium can further reduce the temperature of the electrodes, thereby prolonging their service life. This helps to reduce the maintenance cost of the equipment and improve its reliability.

[0032] The multiple spaced electrodes and partitions can serve as a physical barrier to prevent arcs or sparks generated by discharge from directly contacting other components in the reaction chamber; this helps to improve the safety of the equipment and reduce downtime caused by accidental failure.

[0033] By arranging multiple reaction zones, the cross-zone flow of oxygen atoms can be effectively reduced, and the mutual influence can be reduced.

[0034] Optionally, the partition is bent towards the discharge zone.

[0035] By adopting the above technical scheme, the bent partition can guide the electric field lines, making them more focused on the discharge zone. This focusing effect helps to enhance the electric field strength of the discharge zone, thereby improving the decomposition efficiency of oxygen molecules and the generation rate of ozone.

[0036] By optimizing the distribution and focusing of the electric field, the bent partition can ensure that more electric energy is effectively used to excite oxygen molecules, rather than being wasted in useless space or heat dissipation. This improves the energy utilization rate and reduces energy consumption.

[0037] The bent partition can also serve as an additional channel for the cooling medium, increasing the contact area between the cooling medium and the electrodes and the reaction chamber. This helps to more effectively reduce the temperature of the electrodes and the reaction chamber, preventing equipment failure or ozone decomposition caused by high temperature.

[0038] During high-voltage discharge, arc discharge is a potential safety hazard. The bent partition can serve as a physical barrier to reduce the likelihood of arc discharge and improve the safety of the equipment.

[0039] By optimizing the electric field distribution and enhancing the cooling effect, the bent partition helps to maintain stable temperature and pressure conditions in the reaction chamber. This helps to improve the overall stability of the equipment and reduce performance degradation caused by fluctuations in conditions.

[0040] The bent partition can reduce the movement of oxygen or oxygen atoms to the edge, allowing oxygen molecules to fully contact the electric field and improve the decomposition effect.

[0041] Optionally, the material of the partition plate has heat conduction performance, and a containing cavity is arranged in the partition plate, and a second cross pipe is arranged in the containing cavity, the second cross pipe is attached to the containing cavity and has heat conduction performance, a plurality of jet pipes are arranged on the second cross pipe, the jet pipes located in the same discharge area and on different partition plates are arranged alternately, and the jet pipes are inclined along the oxygen movement direction of the discharge area and are used for supplying oxygen.

[0042] By adopting the above technical scheme, the partition plate and the second cross pipe both have heat conduction performance, which means that they can effectively transfer heat. In the ozone generation process, heat is generated in the electrode and the reaction cavity. If the heat is not dissipated in time, it will cause ozone decomposition and equipment performance degradation. Through the heat conduction of the partition plate and the second cross pipe, the heat can be quickly transferred to the cooling medium (such as cooling water), thereby realizing efficient cooling.

[0043] The jet pipes are arranged in an inclined manner along the oxygen movement direction, and the jet pipes located on different partition plates are arranged alternately. This design can ensure that the oxygen is uniformly distributed in the entire discharge area. The inclined jet pipes not only help the oxygen to enter the discharge area better, but also increase the contact time and contact area of the oxygen and the discharge area, thereby improving the generation efficiency of ozone.

[0044] By optimizing the oxygen supply and enhancing the cooling efficiency, this design can ensure that more electrical energy is used to excite oxygen molecules to generate ozone, rather than being wasted on heat dissipation or ineffective oxygen flow. This improves the energy utilization rate and reduces energy consumption.

[0045] Stable oxygen supply and efficient cooling system help to maintain stable temperature and pressure conditions in the reaction cavity. This helps to improve the overall stability of the equipment and reduce performance degradation or failure caused by condition fluctuations.

[0046] By reducing equipment damage and performance degradation caused by high temperature, and optimizing oxygen supply to reduce electrode wear, this design helps to prolong the service life of the equipment. This reduces the maintenance cost of the equipment and improves its economy and reliability. Uniform oxygen supply and efficient cooling system help to generate higher quality ozone.

[0047] The jet pipes help to form laminar flow, slow down the oxygen flow direction, fully diffuse the oxygen molecules, and be affected by the electric field in multiple directions to quickly decompose into oxygen atoms.

[0048] Optionally, the jet pressure of the jet pipe is less than the oxygen supply pressure of the first cross pipe.

[0049] By adopting the above technical solution, the design of jet pressure being less than oxygen supply pressure can ensure that oxygen flows smoothly from the first fork tube into the jet tube and is sprayed out at a lower pressure in the jet tube. This pressure difference helps to form a stable flow of oxygen in the pipeline, reducing turbulence and vortex, thereby improving the stability and uniformity of oxygen supply.

[0050] The lower jet pressure means that less energy needs to be consumed during oxygen supply. This helps to reduce the energy consumption of the equipment and improve energy utilization efficiency. At the same time, reducing energy consumption also helps to reduce the operating cost of the equipment.

[0051] Stable oxygen flow and lower jet pressure help oxygen to better contact the discharge area, thereby improving the efficiency of ozone generation. In the process of ozone generation, oxygen molecules need to obtain enough energy to be excited and decomposed into oxygen atoms, and then combined into ozone. Stable oxygen flow and suitable pressure conditions help to ensure that oxygen molecules can fully receive energy from the discharge area, thereby improving the generation rate and yield of ozone.

[0052] Optionally, the first fork tube is arranged around the first inner tube and forms a coiled coil section, one side of the coil section is in contact with cooling water, and the other side is in contact with the outer electrode for preheating the supplied oxygen.

[0053] By adopting the above technical solution, the design of the coil section in contact with the outer electrode enables the supplied oxygen to absorb the heat of the outer electrode when flowing through the coil section, thereby achieving preheating of the oxygen. Preheating the oxygen helps to improve the energy utilization efficiency in the ozone generation process, as preheated oxygen molecules are more easily excited and decomposed into oxygen atoms, and then combined into ozone; one side of the coil section is in contact with cooling water, which helps to quickly transfer the heat generated by the outer electrode to the cooling water, thereby achieving efficient cooling. An efficient cooling system can ensure that the equipment maintains stable temperature and performance during long-term operation, reducing equipment damage and performance degradation caused by high temperature; the coiled first fork tube design not only achieves preheating of oxygen and heat dissipation of cooling water, but also optimizes the space utilization of the equipment. This compact design makes the equipment more compact, lightweight, easy to install and maintain.

[0054] The contact of the coil section with cooling water and the discharge area can reduce the temperature of the preheated oxygen, reducing the impact on the cooling of the discharge area.

[0055] Optionally, a catalyst screen is arranged between the first inner tube and the second inner tube, and the catalyst screen is located on one side of the exhaust pipe.

[0056] By adopting the above technical solution, the catalyst screen can catalyze the reaction of oxygen molecules into ozone. By arranging the catalyst screen between the first inner tube and the second inner tube, especially near the exhaust pipe side, it can ensure that the ozone generated in the discharge area and the unreacted oxygen pass through the catalyst again before being discharged, thereby improving the generation efficiency of ozone.

[0057] The catalyst screen not only increases the amount of ozone generated, but also optimizes the quality of ozone. Through catalysis, more oxygen molecules can be converted into ozone, while reducing the generation of by-products such as nitrogen oxides, thereby improving the purity of ozone.

[0058] The presence of the catalyst screen can reduce the burden on the discharge area, as part of the conversion of oxygen molecules is taken over by the catalyst. This helps to reduce wear and corrosion of the discharge area, thereby prolonging the service life of the equipment.

[0059] The catalyst screen can stabilize the temperature and pressure conditions during ozone generation. Through catalysis, the reaction can be more stable, reducing fluctuations in temperature and pressure, thereby improving the stability of the equipment.

[0060] Optionally, a plurality of flow resistance holes are arranged in the mesh of the catalyst screen, and dry oxygen flows through the flow resistance holes, which are used to slow down the flow rate of the passing substances.

[0061] By adopting the above technical solution, the design of the flow resistance holes can significantly slow down the flow rate of the substances (such as oxygen and ozone mixture) passing through the catalyst screen. The slowing down of the flow rate allows more time for oxygen molecules to contact the catalyst, thereby improving the efficiency of the catalytic reaction.

[0062] Slowing down the flow rate also helps to reduce turbulence and vortex, so that oxygen molecules can be more evenly distributed on the surface of the catalyst, further improving the reaction efficiency.

[0063] The flow of dry oxygen in the flow resistance holes helps to maintain the dry state of the catalyst screen, preventing catalyst deactivation or performance degradation due to moisture; the design of the flow resistance holes also increases the contact area between oxygen molecules and the catalyst, thereby improving the catalytic effect; by slowing down the flow rate and optimizing the catalytic effect, this design helps to reduce fluctuations in temperature and pressure caused by too fast reaction rate, thereby enhancing the stability of the equipment.

[0064] In summary, the present application includes at least one of the following beneficial technical effects:

[0065] 1. The cooling water system effectively reduces the temperature of the electrodes and reaction chamber, extending the equipment lifespan. It also helps maintain stable reaction conditions and improves ozone generation efficiency. Multiple ozone production units are interconnected through pipelines and valves, allowing for flexible switching as needed, thus improving the system's flexibility and scalability. Additionally, the supplied oxygen can cool the discharge area, enabling simultaneous cooling of both the discharge area and electrodes, improving both cooling effect and efficiency.

[0066] 2. The bent partition can guide the electric field lines, making them more focused on the discharge region. This focusing effect helps to enhance the electric field strength in the discharge region, thereby increasing the decomposition efficiency of oxygen molecules and the ozone generation rate.

[0067] 3. The flow of dry oxygen within the choke orifice helps maintain the dryness of the catalyst mesh, preventing catalyst deactivation or performance degradation due to moisture. The choke orifice design also increases the contact area between oxygen molecules and the catalyst, thereby improving the catalytic effect. By slowing the flow rate and optimizing the catalytic effect, this design helps reduce temperature and pressure fluctuations caused by excessively fast reaction rates, thus enhancing the stability of the equipment.
