Description

Technical Field

[0001] This utility model relates to the technical field of hydrogen peroxide generators, specifically to the water circuit system of a hydrogen peroxide generator. Background Technology

[0002] Current methods for preparing hydrogen peroxide all suffer from complex processes and limitations in increasing concentration. For example, chemical methods involve complex processes and often require complicated post-processing steps such as distillation and concentration. This not only increases costs but may also reduce the stability and purity of hydrogen peroxide. Furthermore, these methods are energy-intensive and generate a large number of byproducts that can pollute the environment.

[0003] Current hydrogen peroxide generators employ traditional electrochemical preparation methods. While electrochemical methods are relatively environmentally friendly, the preparation of high-concentration hydrogen peroxide typically involves extending the reaction time required for the liquid to move through the device or increasing the reaction power, followed by collecting and storing the processed liquid. However, traditional electrochemical methods are prone to problems such as electrode polarization and numerous side reactions, making it difficult to ensure the effective conduct of the reaction and resulting in the inability to obtain a stable and high-concentration hydrogen peroxide solution. Therefore, it is necessary to improve existing hydrogen peroxide generators to enable them to effectively carry out the hydrogen peroxide reaction and thus obtain high-concentration hydrogen peroxide. Utility Model Content

[0004] The existing hydrogen peroxide generators mentioned above generally solve the problem by extending the reaction time required for the liquid to move through the device or increasing the reaction power. However, traditional electrochemical methods are prone to problems such as electrode polarization, numerous side reactions, and inability to guarantee the effective progress of the reaction, resulting in difficulties in obtaining a stable and high-concentration hydrogen peroxide solution. The technical solution adopted by this utility model to solve these problems is as follows:

[0005] A water circuit system for a hydrogen peroxide generator includes a water tank and a hydrogen peroxide module connected to the water tank. The hydrogen peroxide module has an inlet and an outlet. The water tank has a tank cavity, an inlet pipe and an outlet pipe connected to the tank cavity, a circulation component connected to the inlet, and a collection end connected to the outlet. The low-concentration hydrogen peroxide generated by the hydrogen peroxide module is collected in the tank cavity and then transferred back to the hydrogen peroxide module through the circulation component to continue the reaction.

[0006] Furthermore, in some embodiments of this utility model, the circulation assembly includes a pump body located in the water tank cavity and a connecting pipe connecting the water inlet end and the pump body.

[0007] Furthermore, in some embodiments of this utility model, the hydrogen peroxide module is provided with a liquid reaction chamber, an air flow zone, and a gas-solid-liquid reaction zone located between the liquid reaction chamber and the air flow zone, respectively connected to the water inlet and the water outlet.

[0008] Furthermore, in some embodiments of this utility model, an exhaust / exhaust device connected to the airflow zone is also included.

[0009] Furthermore, in some embodiments of this utility model, an electrolyte supply device connected to the water tank is also included.

[0011] Furthermore, in some embodiments of this utility model, the hydrogen peroxide module is provided with a current detection module, and the water tank cavity is provided with a concentration detection module and a water level detection module.

[0012] Furthermore, in some embodiments of this utility model, the water outlet is located on the upper side of the water tank, the hydrogen peroxide module is provided with a transfer member communicating with the water outlet, and the collection end is provided with a collection channel communicating with the water tank cavity. The transfer member is used to guide the liquid from the water outlet to the collection channel.

[0013] Furthermore, in some embodiments of this utility model, the hydrogen peroxide module is provided with a cathode assembly and an anode assembly, the cathode assembly being disposed in the gas-solid-liquid reaction zone, and the anode assembly being located in the liquid reaction chamber.

[0014] Furthermore, in some embodiments of this utility model, the hydrogen peroxide module is provided in multiple groups and arranged in parallel along the vertical direction.

[0015] The beneficial effects of this utility model are as follows:

The described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0026] like Figures 1 to 6The water system shown for a hydrogen peroxide generator includes a water tank 1 and a hydrogen peroxide module 2 connected to the water tank 1. The hydrogen peroxide module 2 has an inlet end 21 and an outlet end 22. The water tank 1 has a water tank cavity 11, an inlet pipe 12 and an outlet pipe 13 connected to the water tank cavity 11, a circulation component 3 connected to the inlet end 21, and a collection end 4 connected to the outlet end 22. The low-concentration hydrogen peroxide generated by the hydrogen peroxide module 2 is collected in the water tank cavity 11 and transferred back to the hydrogen peroxide module 2 through the circulation component 3 to continue the reaction.

[0027] In traditional electrochemical methods, electrode surfaces are prone to polarization at high current densities, causing the effective potential to be occupied by side reactions and reducing the current efficiency of hydrogen peroxide generation. High-power operation exacerbates side reactions and causes local overheating. Due to the instability of hydrogen peroxide, traditional devices lack effective control over temperature, pH, and metal impurities, making it prone to decomposition at high temperatures or under the catalysis of metal ions. In this case, excessively prolonged residence time will reduce the production capacity per unit time, leading to the decomposition of hydrogen peroxide on the electrode surface.

[0028] This invention, by setting up a circulation component, allows the low-concentration hydrogen peroxide generated by the hydrogen peroxide module to be collected in the water tank cavity and then transferred back to the hydrogen peroxide module to continue the reaction. By allowing the liquid to participate in the reaction process multiple times, a step-by-step accumulation reaction is achieved, thereby alleviating electrode polarization and reducing side reaction interference, which helps to increase the final concentration of hydrogen peroxide generated and realize integrated continuous production.

[0029] Specifically, the circulating electrolyte continuously refreshes the reactants on the electrode surface, reducing concentration polarization and maintaining high current efficiency. Furthermore, the circulating process involves multiple reactions at low power, which reduces energy consumption compared to traditional electrochemical methods while achieving the same concentration target. The flow of the circulating liquid also evenly distributes the heat of reaction, preventing localized overheating that could lead to hydrogen peroxide decomposition or equipment damage.

[0030] Compared to the complex operation steps of traditional chemical methods, the continuous operation mode of this invention, which generates and concentrates simultaneously, eliminates the need for intermediate storage and multiple transfers, making it suitable for industrial-scale production.

[0031] like Figure 1 and Figure 4 The water circuit system shown is applied to a hydrogen peroxide generator. The circulation component 3 includes a pump body 31 located in the water tank cavity 11 and a connecting pipe 32 connecting the water inlet 21 and the pump body 31.

[0032] Furthermore, as a preferred embodiment of this utility model and not a limitation, the pump body provides a stable power source for the circulation of liquid. The pump body can overcome the resistance encountered by the liquid in the flow between the pipes and components such as the hydrogen peroxide module and the water tank, ensuring that low-concentration hydrogen peroxide can be smoothly and continuously transported from the water tank cavity to the water inlet of the hydrogen peroxide module through the connecting pipe, thereby achieving efficient liquid circulation and ensuring that the entire reaction cycle proceeds in an orderly manner.

[0033] Optionally, in some embodiments, the flow rate of the liquid can be controlled by the pump body, thereby adjusting the quality of hydrogen peroxide production.

[0034] Optionally, in some embodiments, the connecting pipe is made of a material resistant to hydrogen peroxide to prevent liquid leakage, flow interruption, etc. Optionally, in some embodiments, the connecting pipe can be a flexible hose made of materials such as polytetrafluoroethylene, perfluoroether rubber, or perfluoroethylene propylene.

[0035] like Figure 1 , Figure 6 The water circuit system shown is applied to a hydrogen peroxide generator. The hydrogen peroxide module 2 is provided with a liquid reaction chamber 23, an air flow zone 24, and a gas-solid-liquid reaction zone 25 located between the liquid reaction chamber 23 and the air flow zone 24, which are respectively connected to the water inlet 21 and the water outlet 22.

[0036] The hydrogen peroxide module 2 is provided with a cathode assembly 231 and an anode assembly 232. The cathode assembly 231 is located in the gas-solid-liquid reaction zone 25, and the anode assembly 232 is located in the liquid reaction chamber 23.

[0037] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the hydrogen peroxide module is provided with a cathode assembly and an anode assembly. The cathode assembly has a hydrophobic and breathable layer in the gas-solid-liquid reaction zone. Adjacent phase interface reaction zones, i.e., gas-solid-liquid reaction zones, are formed on both sides of the hydrophobic and breathable layer. One side of the gas-solid-liquid 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, the gas-solid critical surface increases the contact area between the cathode and oxygen in the air, providing a sufficient and continuous oxygen source for the cathode reaction. This allows oxygen to be more fully utilized by the cathode, providing a continuous oxygen supply for the cathode reaction. The other side of the hydrophobic and breathable layer forms a solid-liquid critical surface with the electrolyte in the liquid reaction chamber, 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 hydrogen peroxide module produces hydrogen peroxide electrochemically. During the electrochemical reaction, an oxygen reduction reaction occurs on the cathode surface to generate hydrogen peroxide.

[0038] O2+ 2H + + 2e - → H2O2;

[0039] Simultaneously, an oxidation reaction occurs on the anode surface to generate oxygen:

[0040] 2H₂O → O₂ + 4H + + 4e - ;

[0041] The overall reaction of the entire electrolysis process is 2H2O + O2 → 2H2O2.

[0042] Therefore, it can be concluded that the hydrogen peroxide module undergoes a gas-liquid reaction during the electrochemical reaction. On the cathode surface of the hydrogen peroxide module, hydrogen ions react with oxygen in the air to undergo an oxygen reduction reaction.

[0043] The liquid reaction chamber of this invention ensures sufficient contact between the electrolyte and the electrode surface, maintaining a stable electrochemical reaction. The gas-solid-liquid reaction zone increases the gas-liquid contact area, promoting O2 dissolution and migration to the electrode interface. The air flow zone continuously introduces air or oxygen, providing sufficient O2 for the reaction and avoiding reaction stagnation caused by insufficient dissolved oxygen in traditional methods.

[0044] like Figures 1 to 3 The water system shown for the hydrogen peroxide generator also includes an exhaust / exhaust device 6 connected to the air flow zone 24.

[0045] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, as the electrochemical reaction proceeds, oxygen in the air will be continuously consumed. Therefore, the exhaust device can not only reduce the temperature inside the chamber, but also provide sufficient oxygen for the hydrogen peroxide module to carry out the electrochemical reaction, effectively improving the efficiency of the hydrogen peroxide module in generating hydrogen peroxide.

[0046] Specifically, the exhaust device can actively extract and discharge air from the air flow zone, and can control parameters such as air flow rate, velocity, and direction of entry and exit, to ensure that air can be continuously supplied from the air flow zone to the gas-solid-liquid reaction zone in a preset stable state, so that the gas-liquid reaction can proceed in an orderly manner under suitable and constant air conditions, avoiding reaction fluctuations caused by unstable air supply, and ensuring the continuity and stability of the hydrogen peroxide generation reaction.

[0047] like Figure 1 The water system shown for the hydrogen peroxide generator also includes an electrolyte supply device 5 connected to the water tank 1.

[0048] Furthermore, as a preferred embodiment of this utility model and not a limitation, in the electrochemical preparation of hydrogen peroxide, the electrolyte is continuously consumed as the reaction proceeds. The electrolyte supply device is connected to a water tank, enabling timely and appropriate replenishment of electrolyte to the reaction system, ensuring that the electrolyte concentration within the system remains at a suitable level. This guarantees the stable conditions required for the electrochemical reaction, allowing the reaction to proceed continuously, stably, and effectively, and preventing situations where insufficient electrolyte leads to reduced reaction efficiency or failure to proceed normally.

[0049] Specifically, the electrolyte supply device stores a high concentration of sodium sulfate solution. When an electrolyte deficiency is detected, the sodium sulfate solution can be transferred from the electrolyte supply device to the water tank by calculating the mixing amount.

[0050] like Figure 1 and Figure 3 The water system shown is used in a hydrogen peroxide generator, and the drain pipe 13 is connected to a first control valve 131 and a manual drain valve 132.

[0051] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the first control valve is configured to control the discharge flow rate. According to actual production needs, reaction stages, and subsequent arrangements for the discharge liquid, the operator can remotely control the valve or automatically adjust the opening of the first control valve according to the set time and conditions to adjust the discharge speed and flow rate.

[0052] In addition, in the event of emergencies, such as failure of the automated control system, power outage, or the need for rapid liquid drainage, operators can directly operate the manual drain valve to quickly open or close the drain channel, thereby achieving emergency discharge or blockage of the liquid. This enhances the emergency response capability of the entire device in special circumstances and ensures the safety of the device and its surrounding environment.

[0053] like Figure 1 The water circuit system shown is used in a hydrogen peroxide generator. The hydrogen peroxide module 2 is equipped with a current detection module 26, and the water tank cavity 11 is equipped with a concentration detection module 14 and a water level detection module 15.

[0054] Optionally, in some embodiments, the current detection module can monitor the current within the hydrogen peroxide module in real time. Based on the current value fed back by the current detection module, the operator can further analyze the conductivity of the reaction system, the working state of the electrodes, and other conditions to adjust reaction conditions such as electrolyte concentration and electrode voltage, so that the reaction can proceed under more optimal electrical parameters, thereby improving reaction efficiency and helping to obtain higher concentrations and more stable hydrogen peroxide.

[0055] Optionally, in some embodiments, the concentration detection module can detect the concentration of hydrogen peroxide in the water tank cavity in real time. For low-concentration products that do not meet the requirements, it can help to discover problems such as abnormal raw material ratios and fluctuations in reaction conditions that may occur during the reaction process. Operators can take corresponding measures in a timely manner, such as adjusting the reaction time and the number of cycles, to ensure that the final hydrogen peroxide produced meets the quality requirements of the actual application scenario.

[0056] Optionally, in some embodiments, the water level detection module can monitor the water level in the water tank cavity in real time. When the water level is too high and approaches or reaches the warning value, it can promptly issue an alarm signal to remind personnel to take appropriate measures, such as suspending liquid intake or starting liquid drainage, to prevent the liquid in the tank from overflowing due to excessive water level, and to prevent liquid leakage from causing safety hazards such as corrosion and pollution to the surrounding environment, thus ensuring the safety of the device and the surrounding environment. The water level detection module also detects when the water level is too low and issues a warning to prevent related components such as pumps from running dry due to lack of water, thus avoiding damage to components, extending the service life of the device, and ensuring the continuous and stable operation of the device.

[0057] like Figure 1 and Figure 3 The water circuit system shown is applied to a hydrogen peroxide generator. The water outlet 22 is located on the upper side of the water tank 1. The hydrogen peroxide module 2 is provided with a transfer member 27 that communicates with the water outlet 22. The collecting end 4 is provided with a collecting channel 41 that communicates with the water tank cavity 11. The transfer member 27 is used to guide the liquid from the water outlet 22 to the collecting channel 41.

[0058] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the water outlet is located on the upper side of the water tank. With the guidance effect of the transfer component, the liquid's own weight is used to achieve natural backflow from the hydrogen peroxide module to the water tank, reducing dependence on the pump body.

[0059] Specifically, the transfer unit guides the hydrogen peroxide-containing liquid into the water tank cavity in a laminar flow along the collection channel, avoiding concentration dilution caused by vigorous mixing with the existing liquid. With the help of the transfer unit and the collection channel, the liquid generated by the hydrogen peroxide module can be efficiently returned to the water tank cavity, and then transported back to the hydrogen peroxide module through the circulation component to continue participating in the reaction. This helps to accelerate the liquid circulation speed, allowing the liquid to circulate and react multiple times within the device, improving the utilization rate of raw materials and the generation efficiency of hydrogen peroxide, and making it more conducive to obtaining high-concentration hydrogen peroxide products.

[0060] Furthermore, the design of the water outlet being located on the upper side of the water tank makes it easier for staff to observe the liquid flow during routine inspections, allowing them to visually determine whether the liquid flow rate and state are normal. The upper water outlet and transfer device are connected via a quick-release mechanism, enabling the hydrogen peroxide module to be separated for maintenance without emptying the water tank.

[0061] like Figures 1 to 4 The water circuit system shown is used in a hydrogen peroxide generator. The hydrogen peroxide module 2 is provided in multiple sets and arranged in parallel along the vertical direction.

[0062] Furthermore, as a preferred embodiment of this utility model and not a limitation, multiple sets of hydrogen peroxide modules are provided, enabling more reaction units to simultaneously carry out the hydrogen peroxide preparation reaction within the same time period. Compared to a single set of modules, multiple parallel sets can significantly increase the amount of raw materials participating in the reaction per unit time, thereby increasing the overall hydrogen peroxide production and effectively improving the production efficiency of the entire device to meet the needs of larger-scale production.

[0063] Specifically, multiple hydrogen peroxide modules are arranged parallel to each other in the vertical direction, making full use of the vertical space of the device and making the overall structure more compact. Compared with arranging multiple modules in a distributed manner on a plane, this layout can accommodate more hydrogen peroxide modules in a limited area, improving space utilization and facilitating the installation and layout of the device in factories of different sizes and other locations.

[0064] Furthermore, each hydrogen peroxide module can be controlled and adjusted relatively independently. Operators can adjust reaction conditions such as reaction temperature, current intensity, and liquid flow rate for different modules according to actual production needs, achieving refined management of the reaction process of each module. For example, parameters can be appropriately increased for modules that require faster reaction speeds, while troubleshooting and parameter adjustments can be performed individually for modules exhibiting abnormal reactions, making the entire production process more flexible and controllable.

[0065] In addition, if one of the modules malfunctions, such as electrode damage or abnormal gas-liquid supply, the other normal modules can still continue the reaction, preventing a complete interruption of the hydrogen peroxide production process and ensuring the continuity and stability of production.

The low-concentration hydrogen peroxide generated by the hydrogen peroxide module 2 is collected in the water tank cavity 11 and transferred back to the hydrogen peroxide module 2 through the circulation component 3 to continue the reaction.

[0068] This invention, by setting up a circulation component 3, allows the low-concentration hydrogen peroxide generated by the hydrogen peroxide module 2 to be collected in the water tank cavity 11 and then transferred back to the hydrogen peroxide module 2 to continue the reaction. By allowing the liquid to participate in the reaction process multiple times, the reaction is accumulated step by step, thereby alleviating electrode polarization and reducing side reaction interference, which helps to increase the final concentration of hydrogen peroxide generated and realize integrated continuous production.

[0069] The circulation assembly 3 includes a pump body 31 located in the water tank cavity 11 and a connecting pipe 32 connecting the water inlet end 21 and the pump body 31.
