Technical Field

[0001] This utility model relates to the field of hydrogen peroxide preparation technology, specifically a hydrogen peroxide generator. Background Technology

[0002] In the fields of chemical engineering, environmental protection, and medicine, hydrogen peroxide is an important strong oxidant and disinfectant, and its on-site preparation technology has attracted widespread attention. Nowadays, most hydrogen peroxide generators on the market adopt an integrated design, which includes a reaction module, a liquid storage device, and a control module. However, the reaction module generates heat when producing hydrogen peroxide by electrochemical method. Therefore, the heat generated by the reaction module may cause damage to the tightly stacked functional components due to high temperature or create safety hazards.

[0003] Therefore, this invention requires the development of a hydrogen peroxide generator to solve the problem that the heat generated by the reaction module in the existing integrated hydrogen peroxide generator design can easily damage various functional components or create safety hazards.

[0027] Please see Figures 1 to 7 The hydrogen peroxide generator shown includes a housing 1, a reaction module 2, a liquid storage device 3 and a control module disposed within the housing 1. The housing 1 also includes an electrical control box 11 for installing the control module and a partition bracket 12 for separating the reaction module 2 and the liquid storage device 3.

[0028] In this invention, the housing serves as the outer shell of the entire device, housing and protecting all internal components. The reaction module is responsible for producing hydrogen peroxide electrochemically. Therefore, the reaction module generates heat during hydrogen peroxide production. Furthermore, the storage device stores the raw materials and the generated hydrogen peroxide solution. The control module monitors and regulates the overall operating status of the device. By installing a dedicated electrical control box within the housing for the control module, heat transfer between it and the reaction module can be effectively isolated, reducing the impact of high temperatures on electronic components. Simultaneously, by physically separating the reaction module and the storage device with a partition bracket, the rate at which heat generated by the reaction module is transferred to the storage device can be effectively reduced, thus preventing hydrogen peroxide decomposition due to excessively high temperatures in the storage device. Therefore, the electrical control box and partition bracket effectively improve the safety and stability of the hydrogen peroxide generator.

[0029] Furthermore, the reaction module is a critical-plane electrochemical hydrogen peroxide generator, which includes a cathode assembly and an anode assembly. The cathode assembly has a hydrophobic and permeable layer, and the hydrophobic and permeable layer has a near-phase interface reaction zone. One side of the near-phase interface reaction zone forms a gas-solid critical surface with air, allowing the cathode reaction to utilize oxygen from the air instead of solely relying on dissolved oxygen in the electrolyte. Compared to traditional processes limited by dissolved oxygen in water, this provides a sufficient and continuous oxygen source for the cathode reaction, enabling more efficient utilization of oxygen and a continuous oxygen supply. The other side forms a solid-liquid critical surface with the electrolyte in the reaction module. This gas-solid critical surface increases the contact area between the cathode and oxygen in the air. The other side of the near-phase interface reaction zone forms a solid-liquid critical surface with the electrolyte in the reaction module, allowing the reaction to proceed continuously, thereby improving the efficiency and equilibrium concentration of the electrochemical synthesis product and ensuring the continuous preparation of high-concentration products. Specifically, the reaction module produces hydrogen peroxide electrochemically. During the electrochemical reaction, an oxygen reduction reaction occurs on the cathode surface to generate hydrogen peroxide.

[0030] O2+ 2H + + 2e - → H2O2;

[0031] Simultaneously, an oxidation reaction occurs on the anode surface to generate oxygen:

[0032] 2H₂O → O₂ + 4H + + 4e - ;

[0033] The overall reaction of the entire electrolysis process is 2H2O + O2 → 2H2O2.

[0034] Therefore, it can be seen that the reaction module undergoes a gas-liquid reaction during the electrochemical reaction. On the cathode surface of the reaction module, hydrogen ions react with oxygen in the air to undergo an oxygen reduction reaction. As the electrochemical reaction proceeds, the oxygen in the air is continuously consumed. Therefore, the heat dissipation component can not only reduce the temperature inside the chamber, but also provide sufficient oxygen for the reaction module to carry out the electrochemical reaction, effectively improving the efficiency of the reaction module in generating hydrogen peroxide.

[0035] Furthermore, it includes a heat dissipation assembly 4, which includes a first exhaust section 41 disposed on the side of the housing 1, a first exhaust fan 42 connected to the first exhaust section 41, and a first air intake section 43 disposed at the bottom of the housing 1.

[0036] In this invention, the first exhaust section is located on the side of the housing, serving as the main channel for hot air exhaust. It quickly removes the heat generated by the reaction module during operation, preventing heat accumulation inside the housing. The first exhaust fan is directly connected to the first exhaust section, accelerating the flow of hot air inside the housing through active ventilation, thereby improving heat dissipation efficiency. Furthermore, the first air intake section at the bottom of the housing introduces external cold air, creating effective air convection. Specifically, after entering from the bottom of the housing, the cold air rises naturally, carrying away the heat generated by the reaction module, and is finally exhausted through the first exhaust section. This "bottom-in, top-out" airflow design conforms to the physical law of hot air rising, significantly improving heat dissipation. In summary, by introducing cold air through the first air intake section and exhausting hot air from the first exhaust section using the first exhaust fan, a complete air circulation system is formed. The combination of active ventilation and passive air intake quickly removes the heat generated by the reaction module, maintaining the internal temperature of the equipment within a safe range. This reduces damage to functional components or potential safety hazards caused by high temperatures, improving the overall reliability and safety of the equipment.

[0037] Furthermore, the electrical control box 11 is located on the side of the box body 1, and the heat dissipation assembly 4 includes a second exhaust section 44 disposed on the side of the electrical control box 11, a second exhaust fan 45 connected to the second exhaust section 44, and a second air intake section 46 disposed at the bottom of the electrical control box 11.

[0038] In this invention, the second exhaust section is located on the side of the electrical control box, serving as the main channel for exhausting hot air from inside the box. It can quickly remove heat generated during the operation of the control module or transferred from the reaction module to the outside of the control box. The second exhaust fan is directly connected to the second exhaust section, accelerating the flow of hot air inside the control box through active ventilation, thereby improving heat dissipation efficiency. Correspondingly, the second air intake section is located at the bottom of the control box, used to introduce external cold air to form effective air convection. Specifically, after entering from the bottom of the control box, the cold air naturally rises, carrying away the heat inside the control box, and is finally discharged through the second exhaust section. This also adopts a "bottom-in, top-out" airflow design, conforming to the physical law of hot air rising, significantly improving heat dissipation. In summary, by equipping the control box with independent heat dissipation components—the second exhaust section, the second exhaust fan, and the second air intake section—not only is the problem of control module failure caused by heat accumulation in existing integrated equipment solved, but the overall performance and safety of the equipment are further improved, effectively preventing damage to the control module caused by overheating inside the control box.

[0039] Furthermore, the reaction module 2 is located on the upper side inside the housing 1 and is connected to the partition bracket 12, while the liquid storage device 3 is located on the lower side inside the housing 1 and is separate from the partition bracket 12.

[0040] In this invention, the reaction module is installed in the upper part of the housing and connected to the partition bracket, while the liquid storage device is installed in the lower part of the housing and separated from the partition bracket. This design utilizes the physical characteristic of hot air rising naturally, allowing the heat generated by the reaction module to be more effectively dissipated through the heat dissipation components. It also reduces the impact of high temperatures on the liquid storage device below, lowering the risk of liquid evaporation or leakage due to overheating. Furthermore, the partition bracket separates the reaction module from the liquid storage device, preventing direct contact and reducing heat transfer from the reaction module to the liquid storage device while providing support for the reaction module, thus enhancing the overall structural strength of the equipment. In summary, by placing the reaction module on the upper side and the liquid storage device on the lower side, the design fully utilizes the principle of hot air rising, making heat dissipation easier and protecting the liquid storage device from high temperatures. This further optimizes the heat distribution inside the hydrogen peroxide generator, improving the safety and stability of the equipment.

[0041] Furthermore, the first exhaust section 41 is located on the upper side of the side of the housing 1, and the second exhaust section 44 is located on the upper side of the side of the electrical control box 11.

[0042] In this invention, due to the physical property of hot air rising, placing the first exhaust section on the upper side of the side of the housing can more efficiently dissipate the heat generated by the reaction module, preventing heat from accumulating inside the housing. Similarly, placing the second exhaust section on the upper side of the side of the electrical control box can utilize the principle of hot air rising to quickly dissipate the hot air inside the electrical control box, while preventing the dissipated hot air from re-entering the electrical control box, thereby improving heat dissipation efficiency and ensuring that the operating temperature of electronic components is within a safe range, effectively improving the safety and stability of the hydrogen peroxide generator.

[0043] Furthermore, the first exhaust section 41 is provided with a plurality of parts, and at least one first exhaust section 41 is provided on the side of the housing 1 away from the first air intake section 43.

[0044] In this invention, the first exhaust section is provided in multiple locations, with at least one first exhaust section located on the side of the housing away from the first air inlet section. This means that at least one first exhaust section is located on the side of the housing opposite to or far from the first air inlet section. This design promotes air convection. Placing the first exhaust section and the first air inlet section on opposite sides maximizes the use of the internal space of the housing, promotes effective space circulation, and allows cold air entering from one side to fully pass through the entire interior of the housing before being discharged from the other side, carrying away more heat. At the same time, it can also prevent short-circuit effects. If the first exhaust section and the first air inlet section are too close, some cold air may be discharged from the housing without fully participating in heat exchange. This layout can effectively avoid the occurrence of such short-circuit effects, ensuring that the heat generated by the reaction module is effectively carried out, and effectively improving the overall safety and reliability of the hydrogen peroxide generator.

[0045] Furthermore, it includes a water pump 5 disposed inside the housing 1, the water pump 5 being connected to the bottom of the housing 1 and located above the first exhaust section 41.

[0046] In this invention, the water pump provides power for the raw material to flow into the storage device, ensuring that the raw material can be transported into the storage device. By connecting the water pump to the bottom of the housing, its installation is ensured to be stable, reducing loosening or damage caused by vibration or transportation. Furthermore, by placing the water pump on the upper side of the first exhaust section, efficient cooling of the water pump can be achieved. Specifically, when the first exhaust fan is running, the suction it generates can promote the flow of external air from the first air intake into the housing. At this time, the water pump located on the upper side of the first air intake can fully contact the cold air, thereby removing the heat from the water pump and preventing damage or malfunction of the water pump due to excessive temperature. At the same time, liquid that may leak from the water pump can flow out of the housing through the first air intake, preventing liquid from accumulating inside the housing and causing short circuits in other circuit components, effectively improving the safety and reliability of the hydrogen peroxide generator.

[0047] Furthermore, the liquid storage device 3 is provided with a first inlet 31 for external liquid to flow in and a first outlet 32 ​​for internal liquid to flow out. Both the first inlet 31 and the first outlet 32 ​​are located on the side of the liquid storage device 3 near the water pump 5.

[0048] In this invention, the first inlet and the first outlet are located on the side of the liquid storage device near the water pump, which can effectively shorten the flow path of the liquid from the water pump to the liquid storage device, thereby shortening the length of the hose connecting the water pump and the liquid storage device, reducing fluid resistance, improving liquid delivery efficiency, and also facilitating pipeline connection and maintenance.

[0049] Furthermore, the liquid storage device 3 is provided with a second liquid outlet 33 on its upper side for supplying liquid to the reaction module 2, and the reaction module 2 is provided with a second liquid inlet 34 connected to the second liquid outlet 33 via a hose. The second liquid outlet 33 and the second liquid inlet 34 are both close to the same side of the housing 1.

[0050] In this invention, the second liquid outlet and the second liquid inlet are connected by a flexible hose to transfer the raw materials or hydrogen peroxide in the storage device to the reaction module for electrochemical reaction to produce hydrogen peroxide. By arranging the second liquid outlet and the second liquid inlet on the same side near the housing, the liquid transport path from the storage device to the reaction module can be effectively shortened, fluid resistance can be reduced, liquid transport efficiency can be improved, and the risk of failure caused by poor liquid transport or pipeline problems can be reduced, thus improving the stability and reliability of equipment operation. In addition, the centralized arrangement of liquid interfaces reduces the possibility of pipeline crossing or disorder and optimizes the internal space layout of the housing, making it easier for operators to install, inspect and maintain.

[0051] Furthermore, the liquid storage device 3 is equipped with multiple liquid supply pumps 35. The liquid supply pumps 35 are connected to the second liquid outlet 33 through hoses. Each liquid supply pump 35 corresponds to one of the second liquid outlets 33. The liquid supply pumps 35 can provide power to transport the raw materials or hydrogen peroxide in the liquid storage device 3 to the reaction module 2 for electrochemical reaction.

[0052] Furthermore, it includes a raw material conveying device 6 disposed inside the box 1 and connected to the side of the box 1, wherein the raw material conveying device 6 and the water pump 5 are located on the same side inside the box 1.

[0053] In this invention, the raw material conveying device is used to connect the external environment and the water pump, so that external raw materials can be conveyed to the liquid storage device through the raw material conveying device and the water pump. Specifically, the raw material conveying device is connected to the water pump through a hose, and the water pump is connected to the liquid storage device through a hose, so that external raw materials can be conveyed to the inside of the liquid storage device through the raw material conveying device and the water pump. Furthermore, by setting the raw material conveying device and the water pump on the same side of the box, the liquid conveying-related components can be centrally managed, avoiding pipe confusion or intersection, optimizing the internal space layout of the box, and facilitating installation, inspection and maintenance by operators.

[0054] Specifically, in order to form a high concentration of hydrogen peroxide, the storage device and the reaction module are connected by a hose. The supply pump in the storage device transports the raw materials in the storage device to the reaction module for electrochemical reaction to produce hydrogen peroxide. The solution after electrochemical reaction flows back into the storage device from the reaction module, and then is transported back to the reaction module by the supply pump for electrochemical reaction again. By repeating this step, the concentration of hydrogen peroxide in the solution can be continuously increased, thereby obtaining a high concentration of hydrogen peroxide solution.
