Description

Technical Field

[0001] The utility model relates to a high-concentration nano-bubble hydrogen-rich water generating device, belonging to the technical field of micro-nano bubble preparation. Background Art

[0002] Due to the selective antioxidant effect of hydrogen, it has attracted extensive attention from scholars in the biomedical field. The biological activity of hydrogen and its role in the prevention and treatment of various diseases have also quickly become research hotspots. Hydrogen has good prevention and treatment effects on various diseases such as radiation injury, metabolic syndrome, organ ischemia, arteriosclerosis, fatty liver, oxygen poisoning, diabetes, organ and system inflammation, uremia, Parkinson's disease, carbon monoxide poisoning, etc. As a therapeutic gas, the most direct and effective application method at present is to use water as a carrier, and prepare hydrogen-rich water by mixing hydrogen into water, and drink it into the body to achieve the therapeutic effect.

[0003] However, the solubility of hydrogen in water is low, and it is difficult to store, and it is easy to escape. The hydrogen concentration in hydrogen-rich water affects its improvement effect on diseases. The higher the hydrogen concentration, the more beneficial it is to the therapeutic effect. How to improve and maintain the concentration and stability of saturated hydrogen in water has become the main problem in the application of hydrogen-rich water.

To further illustrate the high-concentration nano-bubble hydrogen-rich water generating device of the present utility model, the present utility model also provides a process for producing high-concentration nano-bubble hydrogen-rich water using the high-concentration nano-bubble hydrogen-rich water generating device of the present utility model. Among them, the process includes the following steps:

[0020] The hydrogen supply system pressurizes and transports hydrogen gas to a stirring mixer filled with a certain amount of water. Through the rapid stirring of the stirring mixer, the initial mixing of hydrogen gas and water is achieved and a certain amount of bubbles are generated. Subsequently, the hydrogen-water mixture is pressurized by the pressurizing chamber and then divided and input into each spiral tube located in the variable-temperature storage tank. In the spiral tube, hydrogen gas and water further contact to achieve the full contact of hydrogen gas and water. After passing through the spiral tube, it flows into the Venturi tube. The high-pressure hydrogen-water mixture passes through the Venturi tube. Due to the Venturi effect, that is, the cross-section gradually increases, the speed and pressure of the hydrogen-water mixture gradually decrease, and the flow velocity distribution also changes accordingly, becoming uneven. And the hydrogen-water mixture is separated from the uneven inner wall surface, forming an eddy current area. The uneven flow velocity of the gas-liquid mixture, that is, the hydrogen-water mixture, and the appearance of the eddy current area cause the bubbles in the gas-liquid mixture to further collide, and the bubbles are further broken to form smaller micro-nano bubbles. The liquid after passing through the Venturi tube converges into the conical water tank. The bottom of the conical water tank is a downwardly concave conical structure. The impact of the liquid on the water tank wall further causes the bubbles in the liquid to break, forming a large number of nano-bubbles, further improving the mixing strength and effect, thereby increasing the hydrogen content in the water. The water sprayed out from the Venturi tube will concentrate at the bottom of the conical water tank, which is more conducive to the discharge of water. After discharge, high-concentration nano-bubble hydrogen-rich water is obtained.

[0021] In the process for producing high-concentration nano-bubble hydrogen-rich water described above of the present utility model, the temperature of the variable-temperature storage tank is controlled at -20 to 60 °C to further increase the solubility of hydrogen gas in water.

[0022] In the process of producing high-concentration nano-bubble hydrogen-rich water described above in the present utility model, the rotation speed of the stirring mixer is controlled to be 200 - 2000 r / min.

[0023] In the process of producing high-concentration nano-bubble hydrogen-rich water described above in the present utility model, the hydrogen-water mixture is pressurized by a pressurization chamber, and the pressure range for pressurization is 0.1 - 5 MPa.

[0024] Compared with the prior art, the beneficial technical effects that the present utility model can achieve include:

[0025] The high-concentration nano-bubble hydrogen-rich water generating device provided by the present utility model is based on the principle of pressurized variable-temperature dissolved gas, and adopts a unique spiral shunt + Venturi structure design, forming a structure that can make the gas-liquid mixture contact, collide, and break multiple times.

[0048] The pressurization chamber 300 includes one or more pressurization pumps and compressors.

The output ends of multiple groups of Venturi tubes 330 extend into the conical water tank 340, and a manual valve 350 is provided at the output end of the conical water tank 340.

[0049] To more clearly illustrate the high-concentration nano-bubble hydrogen-rich water generation device provided in Embodiment 1 of the present invention, the process of producing high-concentration nano-bubble hydrogen-rich water using the high-concentration nano-bubble hydrogen-rich water generation device will now be introduced in detail. Among them, the process specifically includes the following steps:

[0050] The first water tank 100 is used to hold normal-temperature water (pure water). The control valve 110 controls the flow rate of the normal-temperature water entering the stirring mixer 120. The second water tank 200 provides water source for the hydrogen electrolyzer 210. The compressor 220 sends the hydrogen generated by the hydrogen electrolyzer 210 into the stirring mixer 120 at a pressure of 0.3 MPa. The check valve 230 prevents liquid backflow. Pure water and hydrogen are mixed in the stirring mixer 120. The rotation speed of the stirring mixer 120 is 1200 r / min. Rapid stirring realizes the preliminary mixing of hydrogen and water and generates a certain amount of bubbles to obtain a hydrogen-water mixture. In the hydrogen-water mixture, the volume ratio of hydrogen to water is 1:8;

[0051] Subsequently, the hydrogen-water mixture is sent into the pressurization chamber 300. The pressurization chamber 300 pressurizes the hydrogen-water mixture to 0.8 MPa and then shunts and inputs it into each spiral tube 320 located in the variable-temperature storage tank 310. In the spiral tube 320, hydrogen and water are in full contact. At the same time, the temperature of the variable-temperature storage tank 310 is controlled at about 15 °C to increase the solubility of hydrogen in water. After passing through the spiral tube 320, the hydrogen-water mixture flows into the Venturi tube 330. Due to the Venturi effect of the hydrogen-water mixture with high pressure, that is, the cross-section of the pipeline gradually increases, resulting in the gradual decrease of the speed and pressure of the hydrogen-water mixture, and the flow velocity distribution also changes accordingly, becoming uneven. And the hydrogen-water mixture is separated from the uneven wall surface, forming an eddy current area. The uneven flow velocity of the hydrogen-water mixture and the appearance of the eddy current area cause the bubbles in the hydrogen-water mixture to further collide, and the bubbles are further broken to form smaller micro-nano bubbles;

[0052] The liquid flowing through the venturi tube converges into the conical water tank 340. The impact of the liquid on the wall of the conical water tank 340 further causes the bubbles in the liquid to break, forming a large number of nano-bubbles, further improving the mixing effect, thereby increasing the hydrogen content in the water. Finally, high-concentration nano-bubble hydrogen-rich water is obtained and discharged from the output end at the bottom of the conical water tank 340. It is known through testing that in this embodiment, approximately 6 billion nano-bubbles (average diameter of 134 nm and most frequent diameter of 102 nm) are generated in 1 mL of liquid (industrial pure water).

[0053] Among them, the booster pump in the booster chamber 300 is a self-priming booster pump, which can pressurize the pure water and hydrogen mixture flowing through the pump, that is, the hydrogen-water mixture. At the same time, due to the self-priming effect of the booster pump, it can reduce the conveying pressure of the pure water contained in the first water tank 100, achieving the purpose of not requiring an additional conveying pump when conveying water. In this way, the equipment cost can be effectively reduced.

[0054] The compressor in the booster chamber 300 is a multi-stage compressor, which can meet the refrigeration effect required by the process.

[0055] In summary, the high-concentration nano-bubble hydrogen-rich water generating device and process provided by the embodiments of the present utility model are based on the principle of pressurized variable-temperature dissolved gas, and adopt a unique spiral shunt + venturi structure design, forming a structure that can make the gas-liquid mixture contact, collide, and break multiple times. When the gas-liquid mixture passes through the stirring mixer, booster chamber, variable-temperature storage tank, spiral tube, venturi tube, and conical water tank of the device in sequence, the bubbles in the gas-liquid mixture will break or collide with each other. Through multiple controls such as temperature, pressure, and contact method, nano-bubbles with smaller particle size and larger quantity are obtained, achieving a more stable nano-bubble preparation effect.

[0056] The high-concentration nano-bubble hydrogen-rich water generating device and process provided by the embodiments of the present utility model have the advantages of being able to produce high-concentration nano-bubble hydrogen-rich water, with a simple device structure, low energy consumption, a mature production process, convenient operation, simple use, high preparation efficiency, wide application range, and broad market application prospects.

[0057] The above is only a specific embodiment of the present utility model, and it cannot limit the scope of implementation of the utility model. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the scope of patent protection of the present utility model, should still fall within the scope covered by this patent.
