Description

Technical Field

[0001] This invention relates to the field of water treatment equipment technology, specifically to a hydrogen-rich water production equipment. Background Technology

[0002] With increasing public awareness of healthy drinking water, hydrogen-rich water has gained widespread attention due to its potential benefits such as anti-oxidation and metabolism-boosting effects. Currently, the main production technologies for hydrogen-rich water are physical dissolution and water electrolysis. Physical dissolution typically uses high pressure to dissolve hydrogen in water. This method has simple equipment, but its hydrogen dissolution efficiency is low, and it's difficult to guarantee the stability of hydrogen in water. Water electrolysis produces hydrogen by electrolyzing water, and then mixes the hydrogen with water to create hydrogen-rich water. This method can produce high-concentration hydrogen-rich water and is currently the more commonly used production method.

[0003] In practical applications, existing hydrogen-rich water production equipment has limitations in the hydrogen dissolution efficiency during the mixing process of hydrogen and water, which cannot meet consumers' demand for high-quality hydrogen-rich water. The equipment's disinfection methods are also limited. Chemical disinfection methods may leave chemical residues inside the equipment, affecting the quality of the hydrogen-rich water. High-temperature disinfection methods require maintaining a high-temperature environment for a long time, which is inefficient and consumes a lot of energy, resulting in high costs.

[0004] To address this, we have developed a new type of equipment for producing hydrogen-rich water. Summary of the Invention

[0015] (III) Beneficial Effects

[0016] This invention provides a hydrogen-rich water production device, which has the following beneficial effects:

[0017] 1. This hydrogen-rich water production equipment utilizes a circumferentially arrayed and linearly arranged swirling nozzle within the mixing tank to spray water in a rotating manner, significantly increasing the contact area and time between water and hydrogen. Simultaneously, a spiral-shaped ultraviolet lamp emits specific wavelengths of ultraviolet light that promote hydrogen dissolution, breaking hydrogen bonds between water molecules, reducing water molecule clusters and increasing their activity. The synergistic effect of these two elements significantly improves the dissolution efficiency of hydrogen in water, thereby producing hydrogen-rich water with higher hydrogen concentration and superior quality, better meeting consumer demand for high-quality hydrogen-rich water.

[0018] 2. This hydrogen-rich water production equipment uses ultraviolet lamps to emit ultraviolet light of different wavelengths to convert the oxygen generated by water electrolysis into ozone. Ozone has strong oxidizing properties and can effectively kill bacteria, viruses and other microorganisms in the mixing tank, gas storage tank and related pipelines. It has a good disinfection effect, avoids the problem of chemical residues caused by chemical disinfection, and ensures the quality and safety of hydrogen-rich water. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Examples, such as Figure 1 - Figure 5 As shown, this embodiment of the invention provides a hydrogen-rich water production device, including a housing 1. A hydrogen generator 2, a mixing tank 3, and a storage tank 4 are fixedly installed on the inner wall of the housing 1. The hydrogen generator 2 is the core component for producing hydrogen and oxygen, which decomposes water into hydrogen and oxygen through water electrolysis. The mixing tank 3 is used to fully mix hydrogen and water, so that hydrogen dissolves in the water to form hydrogen-rich water. The storage tank 4 is used to store the hydrogen produced by the hydrogen generator 2 to meet different production needs and ensure the continuity of production.

[0027] The mixing tank 3 is equipped with a spiral-shaped ultraviolet lamp 5 that emits ultraviolet light of different wavelengths. The spiral shape increases the coverage area within the mixing tank 3, allowing for more even irradiation of the water and gas. Different wavelengths of ultraviolet light have different functions. During the hydrogen-rich water production stage, the ultraviolet lamp 5 emits a specific wavelength of ultraviolet light. This specific wavelength precisely breaks the hydrogen bonds between water molecules, reducing the size of larger water molecule clusters and significantly enhancing their activity. This change creates favorable conditions for the dissolution of hydrogen in water, greatly promoting its dissolution. During the equipment disinfection stage, the ultraviolet lamp 5 switches to another specific wavelength, converting the oxygen entering the mixing tank 3 into highly oxidizing ozone. The ozone diffuses, thoroughly disinfecting the mixing tank 3, the gas storage tank 4, and related pipelines, effectively killing various bacteria, viruses, and other microorganisms, ensuring a hygienic and safe internal environment.

[0028] A water inlet 6 is fixedly connected to one end of the mixing tank 3. A water distribution pipe 7 located inside the gas storage tank 4 is fixedly installed at one end of the water inlet 6. Multiple sets of swirling nozzles 8 are fixedly connected in a circumferential array on the side of the water distribution pipe 7. Each set of swirling nozzles 8 is arranged in a linear array. The water inlet 6 is the channel for water to enter the mixing tank 3. The water distribution pipe 7 evenly distributes the water entering from the water inlet 6 to each swirling nozzle 8. The swirling nozzles 8 can make the water spray out in a rotating manner. This rotating water flow can increase the contact area and contact time between water and hydrogen, thereby improving the dissolution efficiency of hydrogen. One end of the mixing tank 3 is fixedly connected to two air inlets 9, and the other end of the mixing tank 3 is fixedly connected to a water outlet 22. The two air inlets 9 are used to introduce hydrogen and oxygen in different working modes. In the hydrogen-rich water production mode, one air inlet 9 is used to introduce hydrogen generated by the hydrogen generator 2 to mix with water. In the equipment disinfection mode, the other air inlet 9 is used to introduce oxygen so that it can be converted into ozone under the action of ultraviolet lamp 5. The water outlet 22 is the channel for the produced hydrogen-rich water to flow out of the mixing tank 3, ensuring the continuous production and output of hydrogen-rich water.

[0029] Specifically, a control module 21 is fixedly installed on the inner wall of the housing 1. Two sets of interfaces are symmetrically arranged on the top of the hydrogen generator 2, including a water inlet / outlet end 10, a gas outlet end 11, and a wiring terminal 12. The control module 21 is electrically connected to the two wiring terminals 12. The control module 21 is the control center of the entire device. By being electrically connected to the wiring terminals 12 of the hydrogen generator 2, it can control the start-up, stop, and electrolysis parameters (such as voltage and current) of the hydrogen generator 2. A water supply pipe is fixedly connected between one water inlet / outlet end 10 and the water inlet 6. The water in the hydrogen generator 2 is discharged into the mixing tank 3 through this water inlet / outlet end 10. The other water inlet / outlet end 10 is connected to an external water source (the water supply pipe and the external water source are existing technologies and are not shown in the figure, so they will not be discussed in detail here). It is used to provide the water required for electrolysis of the hydrogen generator 2. The gas outlet end 11 transports the hydrogen and oxygen generated by the hydrogen generator 2 to the corresponding pipelines for subsequent processing and use.

[0030] A three-position five-way valve 13 is fixedly installed on the inner wall of the housing 1. It consists of a valve body, a valve core, and an electromagnetic control device. When the electromagnetic control device is energized, it generates electromagnetic force to drive the valve core. It has three working positions and five vents (including two inlets, two working ports, and one exhaust port). The valve core position is changed by switching the electromagnetic control device on and off, thereby switching the gas path. The two inlets of the three-position five-way valve 13 are fixedly connected to the two outlets 11 by two first gas supply pipes 14. Each of the two first gas supply pipes 14 is equipped with a one-way valve 15. The three-position five-way valve 13 can achieve precise control of the flow direction of hydrogen and oxygen by switching different working positions. The two first gas supply pipes 14 deliver hydrogen and oxygen generated by the hydrogen generator 2 to the three-position five-way valve 13. The function of the one-way valve 15 is to prevent gas backflow and ensure that hydrogen and oxygen can only flow in the predetermined direction, avoiding equipment failure or safety problems caused by gas backflow.

[0031] The gas storage tank 4 has two gas ports 16 at the top and bottom. A second gas supply pipe 17 is fixedly connected between one working port of the three-position five-way valve 13 and one gas port 16. A third gas supply pipe 18 is fixedly connected between the other working port of the three-position five-way valve 13 and one gas inlet 9. The exhaust port of the three-position five-way valve 13 is connected to the external environment. The control module 21 is also electrically connected to the three-position five-way valve 13 to control the working state of the three-position five-way valve 13. In the hydrogen-rich water production mode, the control module 21 controls the three-position five-way valve 13 to deliver hydrogen through the first gas supply pipe 14 and the third gas supply pipe. 18 is delivered to the inlet 9 of the mixing tank 3 to mix with water; at the same time, oxygen is discharged to the outside through the exhaust port of the three-position five-way valve 13 via the first gas supply pipe 14. In the equipment disinfection mode, the control module 21 controls the three-position five-way valve 13 to deliver hydrogen through the first gas supply pipe 14 and the second gas supply pipe 17 to the gas port 16 of the gas storage tank 4 for storage, and deliver oxygen through the first gas supply pipe 14 and the third gas supply pipe 18 to the inlet 9 of the mixing tank 3 to generate ozone. The two gas ports 16 at the top and bottom of the gas storage tank 4 facilitate the entry, exit and storage management of hydrogen.

[0032] A fourth gas supply pipe 19 is fixedly connected between another gas port 16 and another gas inlet 9. A solenoid valve 20 is installed on the fourth gas supply pipe 19. The solenoid valve 20 is controlled by the control module 21. During the equipment disinfection stage, the gas storage tank 4 performs its hydrogen storage function. The control module 21 precisely regulates the three-position five-way valve 13 to guide the hydrogen generated by the electrolysis of the hydrogen generator 2 into the gas storage tank 4 for storage through the first gas supply pipe 14 and the second gas supply pipe 17. During the hydrogen-rich water production stage, when the mixing tank 3 needs to create a high-pressure environment to improve the hydrogen solubility... At this time, the control module 21 responds quickly and opens the solenoid valve 20 on the fourth gas supply pipe 19. At this time, the hydrogen in the gas storage tank 4 is input into the mixing tank 3 through the fourth gas supply pipe 19. This causes the gas pressure in the mixing tank 3 to rise rapidly and quickly build a high-pressure environment. Under high pressure, the solubility of hydrogen in water increases significantly, creating ideal conditions for the full fusion of hydrogen and water. This efficiently promotes the production of hydrogen-rich water in the mixing tank 3, realizes the flexible allocation of hydrogen, meets different production needs, and ensures the stable quality of hydrogen-rich water.

[0033] Both the gas storage tank 4 and the mixing tank 3 are equipped with pressure sensors (pressure sensors are existing technology and are not shown in the diagram, so they will not be discussed in detail here). The pressure sensor in the mixing tank 3 constantly monitors the pressure inside the tank. Since the solubility of hydrogen in water is related to pressure, a suitable pressure helps improve the hydrogen dissolution efficiency. When the pressure sensor detects that the pressure inside the mixing tank 3 is too low, it will promptly feed the information back to the control module 21. The control module 21 then adjusts the operating parameters of the hydrogen generator 2 to increase the hydrogen production, or controls the three-position five-way valve 13 and the solenoid valve 20 to allow more hydrogen to enter the mixing tank 3 from the gas storage tank 4 through the fourth gas supply pipe 19, thereby increasing the pressure inside the mixing tank 3 and creating favorable conditions for hydrogen dissolution. Conversely, if the pressure is too high, the control module 21 will... 1. Control the relevant valves to release gas and reduce pressure, avoiding damage to the tank body caused by excessively high gas pressure, while ensuring the stability of the hydrogen dissolution process and preventing the quality of hydrogen-rich water from being affected by gas pressure fluctuations; The gas pressure sensor in the gas storage tank 4 monitors the gas pressure of the gas storage tank 4. During the production of hydrogen-rich water, if the gas pressure in the gas storage tank 4 is too low, it may not be able to meet the hydrogen demand of the mixing tank 3, resulting in the obstruction of hydrogen-rich water production. At this time, the gas pressure sensor transmits the signal to the control module 21. The control module 21 adjusts the hydrogen generator 2 to increase the hydrogen output or optimizes the gas delivery path to prioritize the hydrogen storage of the gas storage tank 4. If the gas pressure in the gas storage tank 4 is too high, the control module 21 controls the relevant valves to release gas, ensuring the safety and stability of the gas storage tank 4 and ensuring that it can continuously and stably supply hydrogen to the mixing tank 3.

[0034] Working principle: Hydrogen-rich water production: Control module 21 starts hydrogen generator 2. Water enters hydrogen generator 2 from one inlet / outlet end 10 and is electrolyzed to produce hydrogen and oxygen. At the same time, water flowing out from the other inlet / outlet end 10 of hydrogen generator 2 is sprayed into mixing tank 3 through inlet 6 and water distribution pipe 7 by swirl nozzle 8. Control module 21 controls the three-position five-way valve 13 to switch states, so that hydrogen enters the gas inlet end 9 of mixing tank 3 through the first gas supply pipe 14 and the third gas supply pipe 18, and mixes with water in mixing tank 3; oxygen is discharged from the exhaust port of three-position five-way valve 13 through the first gas supply pipe 14. At this time, the spiral ultraviolet lamp 5 in mixing tank 3 emits ultraviolet light of a specific wavelength to promote the dissolution of hydrogen in water, and the generated hydrogen-rich water flows out from outlet 22.

[0035] Equipment disinfection: The remaining water in the mixing tank 3 is drained. The hydrogen generator 2 continues to work, but it no longer discharges internal water into the mixing tank 3. The control module 21 controls the three-position five-way valve 13 to change the gas flow direction. Hydrogen enters the storage tank 4 through the first gas supply pipe 14 and the second gas supply pipe 17. Oxygen enters the inlet 9 of the mixing tank 3 through another first gas supply pipe 14 and the third gas supply pipe 18. The ultraviolet lamp 5 in the mixing tank 3 emits another specific wavelength of ultraviolet light to convert oxygen into ozone, which disinfects the mixing tank 3, the storage tank 4 and related pipelines. If hydrogen needs to be replenished for subsequent production, the control module 21 can open the solenoid valve 20 on the fourth gas supply pipe 19 to allow the hydrogen in the storage tank 4 to enter the inlet 9 of the mixing tank 3 through the fourth gas supply pipe 19.
