Description

TECHNICAL FIELD

[0001] The utility model relates to hydrogen -rich water preparation technical field, concretely relates to hydrogen -rich water preparation technology under the plateau environment, especially relates to plateau type nanometer bubble hydrogen -rich water generating device. BACKGROUND

[0002] Hydrogen-rich water is a water solution in which hydrogen gas is dissolved by physical or chemical methods, and the hydrogen concentration reaches saturation or supersaturation. Studies have shown that hydrogen has selective antioxidant, anti-inflammatory and cell protection effects, so hydrogen-rich water has broad application prospects in the fields of health drinks, medical assistance and sports rehabilitation. Currently, the mainstream hydrogen-rich water preparation technologies include electrolytic hydrogen production, metal magnesium reaction and high-pressure hydrogenation. Among them, the electrolytic hydrogen production method has become the mainstream technology route of commercial equipment due to its high hydrogen purity and convenient operation.

[0003] According to Henry's law, the solubility of a gas in a liquid is directly proportional to its partial pressure. In the low-pressure environment of the plateau, the partial pressure of hydrogen gas decreases, resulting in a significant decrease in its solubility in water. For example, at an altitude of 3000 meters (atmospheric pressure of about 70 kPa), the solubility of hydrogen gas is reduced by about 30% compared to sea level. Low pressure environment may cause insufficient mixing of gas and liquid, accelerated hydrogen escape, etc., resulting in unstable hydrogen-rich water concentration, and even unable to reach the claimed hydrogen content standard. To maintain the dissolution efficiency, the traditional equipment needs to compensate by increasing the pressure or prolonging the reaction time, but the sealing and pressure resistance of the equipment may decrease in the plateau environment, increasing the risk of leakage. For example:

[0004] The document "Qin Xiujun, Anquan, Zhang Wei, et al. Preliminary study on preparation and preservation method of hydrogen-rich water [J]. Cancer, deformation, mutation, 2013, 25 (6): 457-460." uses the method of increasing pressure to prepare hydrogen-rich water. First, the air pressure in the water is reduced by pre-vacuumizing, then a certain pressure of hydrogen gas is introduced and maintained for a period of time, so that the hydrogen gas is dissolved in the water.

[0005] Chinese utility model patent CN216738558U provides a preparation method of hydrogen-rich water, which includes a pressurized hydrogen enrichment step. Specifically, hydrogen gas is introduced into an ultrasonic atomizer, the gas flow rate is adjusted, the pressure inside the container is steadily increased to a certain value (such as 0.36-0.4 MPa) at a certain rate, and hydrogen-rich water with high hydrogen concentration is obtained. This method combines ultrasonic atomization and single-stage pressurization technology to improve the dissolution efficiency of hydrogen gas.

[0006] Chinese utility model patent CN216738558U discloses a hydrogen-rich water preparation device, which comprises a pressurized hydrogen dissolving part. By setting a second pressurizing device, pure hydrogen is pressurized into a closed hydrogen dissolving water tank to form a high pressure environment, so that hydrogen is more easily dissolved in drinking water. At the same time, the pressurized hydrogen is strongly contacted with the drinking water by using an aeration head, further promoting the dissolution of hydrogen.

[0007] Chinese invention patent CN116535039A provides a preparation method of hydrogen-rich oxygen-rich water, which comprises a pressurizing and oscillating step in a high-pressure sealed container. Pure water, oxygen and hydrogen are simultaneously introduced into the sealed container, and oscillation is performed to accelerate gas dissolution. Subsequently, a cutting net plate is added in the high-pressure sealed container, oxygen and hydrogen are injected, and the container is repeatedly vibrated to break the gas bubbles into smaller sizes, thereby accelerating the fusion of pure water and gas to obtain hydrogen-rich oxygen-rich water. This method uses single-stage pressurization and physical oscillation technology to improve the solubility of gas in water.

[0008] However, the single-stage pressurization technology of the above technical solution relies on the initial pressure to improve the solubility of hydrogen, but in the plateau low-pressure environment, the pressure difference between the initial pressure and the external pressure decreases, resulting in insufficient hydrogen injection power. For example, the device can achieve 1.6 ppm hydrogen concentration under normal pressure, but only 0.8 ppm at an altitude of 4000 meters. In order to make up for the decline in dissolution efficiency, the device needs to prolong the contact time of hydrogen and water.

[0009] Therefore, the present application proposes a plateau type nano bubble hydrogen-rich water generating device. Utility model content

[0010] Therefore, the utility model embodiment hopes to provide a plateau type nano bubble hydrogen-rich water generating device to solve or alleviate the technical problems existing in the prior art, that is, to develop a multi-stage pressurization technology and mixing technology to further adapt to the hydrogen-rich water preparation demand in the plateau environment. The technical scheme of the utility model is as follows:

[0011] The plateau type nano bubble hydrogen-rich water generating device comprises,

[0012] An electrolytic hydrogen generating mechanism 2 for generating hydrogen;

[0013] The multi-stage pressurization and mixing mechanism 3 is connected with the electrolytic hydrogen generating mechanism 2 and the pump group 7, and the pump group 7 is connected with the electrolytic hydrogen generating mechanism 2 and the multi-stage pressurization and mixing mechanism 3.

[0014] The pump group 7 further conducts the hydrogen-rich water and hydrogen to the dissolution and stabilization assembly 4 for further turbulent mixing and dissolution of the hydrogen-rich water.

[0015] In use, the electrolytic hydrogen production mechanism 2 first produces hydrogen, and then the pump group 7 sends the hydrogen to the pump group 7 through the pipe A, and sends it to the multi-stage pressurizing and mixing mechanism 3 through the pipe B, and the multi-stage pressurizing and mixing mechanism 3 mixes the hydrogen with the water body connected to the outside, and relies on a plurality of pressure-decreasing booster units 302 connected in series, the first booster unit 302 performs preliminary mixing at normal pressure, and the subsequent booster units 302 gradually enter the plateau high-pressure environment, thereby shortening the reaction time and improving the dissolution efficiency, and generating hydrogen-rich water;

[0016] Then the pump group 7 extracts the hydrogen-rich water generated by the preliminary mixing through the pipe C and sends it to the pump group 7, and the pump group 7 sends it to the dissolution and stabilization assembly 4 through the pipe D1, and the pump group 7 extracts hydrogen from the electrolytic hydrogen production mechanism 2 through the pipe D2 and the pipe D3, and sends it to the inside of the dissolution and stabilization assembly 4 at the upper end and the lower end, respectively, for secondary pressurization and mixing; finally, the pump group 7 extracts the hydrogen-rich water prepared in the dissolution and stabilization assembly 4 and sends it to the finished product cabin 5 through the pipe E.

[0017] In one embodiment, the electrolytic hydrogen production mechanism 2 includes:

[0018] The electrolytic unit 202 is arranged in the shell 201, and the bottom is provided with a rotational flow shearing assembly 203 for rotational flow shearing and improving the flowability of hydrogen; the rotational flow shearing assembly 203 includes a motor 2031 and a rotating turbine 2032 driven by the motor 2031.

[0019] After the pump group 7 sends the hydrogen to the pump group 7 through the pipe A, it is sent to the multi-stage pressurizing and mixing mechanism 3 through the pipe B.

[0020] The pump group 7 sends the hydrogen to the dissolution and stabilization assembly 4 through the pipe D2 and the pipe D3.

[0021] In one embodiment, the multi-stage pressurizing and mixing mechanism 3 includes:

[0022] The container 301 is connected to the outside water body at the upper part; the container 301 is arranged with a plurality of booster units 302 in series from bottom to top, and the bottommost booster unit 302 mixes the water body with hydrogen at normal pressure, and the remaining booster units 302 at the upper part gradually enter the plateau high-pressure environment.

[0023] The micro-porous dispersion unit 303 is connected to the bottommost booster unit 302.

[0024] Each booster unit 302 includes:

[0025] The pressure chamber 3021 is opened in the container 301, and the gas-liquid mixing pump 3022 is used to mix hydrogen and water.

[0026] The pressure chamber 3021 of the uppermost pressurizing unit 302 is communicated with the pump group 7 through pipe C.

[0027] When the water body is in the pressure chamber 3021, the gas-liquid mixing pump 3022 is responsible for mixing hydrogen and the water body; for all the pressurizing units 302, the bottommost gas-liquid mixing pump 3022 receives the dispersed hydrogen from the microporous dispersion unit 303, then performs gas-liquid mixing; then it is pumped into the pressure chamber 3021 of the upper pressurizing unit 302, and the gas-liquid mixing pump 3022 thereof performs secondary pressurization, and reciprocates in turn; the pressure chamber 3021 of the uppermost pressurizing unit 302 is prepared into preliminary hydrogen-rich water, which is pumped into the pump group 7 through pipe C after being pumped into the pump group 7 by the pump group 7, and then is introduced into the dissolution stabilizing assembly 4 through pipe D1.

[0028] In an embodiment, the microporous dispersion unit 303 includes a cavity composed of an upper end hole array screen plate 3031 for dispersing hydrogen bubbles and a lower end water passage groove plate 3032 for flowing hydrogen, which is fixed in the container 301, and an ultrasonic vibrator 304 is arranged in the cavity for applying vibration force to the hole array screen plate 3031. The hole array screen plate 3031 is responsible for dispersing hydrogen bubbles and breaking the bubbles into micrometer level or even nanometer level in combination with a resonance field, which helps to increase the gas-liquid contact area during subsequent gas-liquid mixing. The side of the hole array screen plate 3031 facing the pressurizing unit 302 is a raised arc surface, which is the contact area for pressurized hydrogen; the hole diameter of the hole array screen plate 3031 is 0.2-0.5 mm.

[0029] In an embodiment, the dissolution stabilizing assembly 4 is composed of three tank bodies with different diameters, each of which is communicated with pipe D1, pipe D2 and pipe D3 of the pump group 7, the hydrogen-rich water prepared by the uppermost pressurizing unit 302 is introduced into the tank bodies, and the hydrogen prepared by the electrolytic hydrogen production mechanism 2 is introduced into the upper tank body and the lower tank body, so as to force the hydrogen and the water to form turbulent flow in the dissolution tank and prolong the contact time.

[0030] The outer shell of the dissolution stabilizing assembly 4 is communicated with a heat transfer pipe 8, the heat transfer pipe 8 transfers the heat of the heater 6 to the outer shell of the dissolution stabilizing assembly 4 for heating, thereby assisting to increase the hydrogen flow in the interior.

[0031] Compared with the prior art, the mechanism for solving the above technical problems of the utility model lies in that:

[0032] (1) The multi-stage pressurization technology solves the problem of hydrogen solubility decline: in the plateau low-pressure environment, according to Henry's law, the solubility of hydrogen in water is proportional to the partial pressure. The traditional single-stage pressurization technology relies on the initial pressure to improve the solubility, but in the plateau environment, the pressure difference between the initial pressure and the external pressure decreases, which leads to insufficient hydrogen injection power and significant decline in dissolution efficiency.

[0033] The utility model discloses a multistage pressurization mixing mechanism 3, this scheme adopts a plurality of pressure decrement's pressure boost unit 302 in series, gradually promotes the contact pressure of hydrogen and water.This design principle is based on the following two points:

[0034] The pressure chamber 3021 of each pressure boost unit 302 is inputted with the mechanical energy of gas-liquid mixing pump 3022, and fluid kinetic energy is converted into pressure energy.In the plateau low pressure environment, by gradually reducing the pressure gradient (Delta P / Delta L), the gas bubble coalescence phenomenon is effectively inhibited, and the stability of the dissolution process is ensured.For example, at an altitude of 4000 meters, although the pressure difference between the initial pressure and the external air pressure is reduced, the multistage pressurization design can maintain the system pressure at 0.6MPa, so that the hydrogen solubility is improved by 2.3 times compared with the traditional single-stage pressurization equipment.The gas-liquid mixing pump 3022 in each pressure boost unit 302 generates a cyclone mixing state, so that the fluid is in a turbulent flow state (Reynolds number Re>4000).Turbulent flow can significantly enhance the mass transfer process of hydrogen to the liquid phase and improve the dissolution efficiency.

[0035] (2) Micropore dispersion and ultrasonic vibration solve the problem of insufficient gas-liquid mixing: in the plateau environment, due to low air pressure, hydrogen bubbles are easy to escape, resulting in insufficient gas-liquid mixing and unstable dissolution efficiency.

[0036] In the utility model, through the micropore dispersion unit 303, the scheme utilizes the hole array sieve plate 3031 and the ultrasonic vibrator 304 to break the hydrogen bubbles to micron level or even nanometer level, significantly increases the gas-liquid contact area; because the high-frequency vibration generated by the ultrasonic vibrator 304 forms a periodic pressure fluctuation on the surface of the hole array sieve plate 3031. When the local pressure is lower than the saturated vapor pressure of hydrogen, the gas molecules nucleate and expand rapidly, generating microjet and shock wave, breaking the hydrogen bubbles to submicron level. Moreover, the arc surface design and specific pore size (0.2-0.5mm) of the sieve plate form a dynamic screening effect under ultrasonic vibration. Large-sized bubbles are trapped and broken again, small-sized bubbles (d<1um) pass through the sieve hole into the pressure boost unit 302, significantly improving the gas-liquid contact efficiency.

[0037] Dissolution stability assembly solves the problem of unstable dissolution efficiency: in the plateau environment, due to the possible decline of equipment sealing performance and pressure resistance, the traditional equipment is prone to leakage risk, resulting in unstable dissolution efficiency.

[0038] In this invention, the solution employs a three-stage series tank design through the dissolution stabilization component 4. This design combines turbulent mass transfer enhancement with a heat-assisted flow mechanism to prolong the contact time between hydrogen and water, thereby improving dissolution efficiency. The variable diameter design of the three-stage tank and the spiral guide plate generate strong turbulence, enhancing the mass transfer process from hydrogen to the liquid phase. Simultaneously, the three-stage gas supply path forms a hydrogen concentration gradient field, driving hydrogen molecules to diffuse towards low-concentration regions. Combined with the convection effect of the turbulent field, this increases the dissolution rate by 2.1 times. The heat transfer pipe 8 transfers heat from the heater 6 to the outer shell of the dissolution stabilization component 4, intensifying the thermal motion of hydrogen molecules and reducing the surface tension of water, thus promoting bubble breakage and dissolution. Furthermore, the heating function also suppresses the decrease in solubility caused by the low temperature environment at high altitudes.

[0039] Compared with the prior art, the beneficial effects of this utility model are:

[0040] I. Breakthrough in Adaptability to Extreme Environments: The multi-stage pressurized mixing mechanism, by progressively reducing the pressure gradient (ΔP / ΔL), can maintain a system pressure of 0.6 MPa at an altitude of 5000 meters (at an atmospheric pressure of 54 kPa), achieving a 2.3-fold increase in solubility compared to traditional equipment. The heat transfer tubes of the dissolution stabilization component maintain the internal temperature at 40±2℃, increasing the kinetic energy of hydrogen molecules through thermal convection (q=hAΔT), overcoming the decrease in solubility caused by the low temperature at high altitudes (solubility increases by 2.3% for every 1℃ increase in temperature).

[0041] II. Exponential Improvement in Dissolution Efficiency: The three-stage tank with variable diameter design induces three-dimensional turbulence (Re>4000), and combined with the Coanda effect induced by the spiral guide plate, the hydrogen dissolution rate is increased by 45% compared to laminar flow. The microporous dispersion unit and ultrasonic vibrator work together to reduce the hydrogen bubble size to below 100nm, increasing the specific surface area by 600 times and improving the dissolution efficiency by 3.7 times. The dissolution stabilization component forms a concentration gradient field (ΔC=1.2ppm) through synchronous gas supply from the upper and lower ends. Combined with the convection-diffusion coupling effect of the turbulent field, the hydrogen molecule flux (J=KmΔC) is increased by 2.1 times. Attached Figure Description

DETAILED DESCRIPTION

[0058] In order to make the above objectives, characteristics and advantages of the present application more apparent, specific embodiments of the present application will be described in detail below with reference to the drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in a number of ways beyond the specific embodiments described and illustrated herein, and it is therefore intended that the present application not be limited in scope to the specific embodiments described and illustrated herein. Indeed, the present application can be practiced in a number of ways beyond the specific embodiments described and illustrated herein, and it is therefore intended that the present application not be limited in scope to the specific embodiments described and illustrated herein.

[0059] Embodiment one: in the prior art, in order to solve the problem of insufficient pressure in the preparation process of hydrogen-rich water, it is often necessary to pre-evacuate to reduce the air partial pressure in the water, then inject hydrogen gas with a certain pressure and maintain for a period of time, so that the hydrogen gas is dissolved in the water. However, in the plateau low-pressure environment, the pressure difference between the initial pressure and the external pressure is reduced, resulting in insufficient hydrogen injection power and reduced dissolution efficiency. Therefore, please refer to Figures 1-7 , the present embodiment will provide a related technical solution to solve the above technical problems:

[0060] The plateau type nano bubble hydrogen-rich water generating device realizes integrated control of multi-stage pressurization and mixing process through modular structure design. The electrolytic hydrogen production mechanism 2 adopts a proton exchange membrane electrolytic cell, takes pure water as raw material, generates oxygen at the anode and hydrogen at the cathode under the action of direct current, and the hydrogen is transported through pipe A of pump set 7 after gas-liquid separation. The multi-stage pressurization and mixing mechanism 3 is composed of a plurality of independent pressurization units 302 connected in series, each pressurization unit 302 includes a high-pressure plunger pump, a spiral static mixer and a pressure sensor, and by gradually reducing the pressurization ratio (such as the first pressurization unit 302 is set to 0.2 MPa, and the last pressurization unit 302 is set to 0.6 MPa), the hydrogen gas and the water body form dynamic mixing in the pressure gradient field. The dissolution stability assembly 4 adopts a double-layer jacket structure, the inner layer is provided with a vortex generator and a microporous aeration disc, the outer layer is maintained at a constant temperature of 25±2℃ by circulating cooling water, and the hydrogen gas is injected from the top and the bottom through pipe D2 and pipe D3 of pump set 7 respectively, and the preliminary hydrogen-rich water transported through pipe C is dissolved in the turbulent field.

[0061] Specifically, the technology is based on the coupling mechanism of gas dissolution dynamics and fluid mechanics. The multi-stage pressurization unit 302 uses the Bernoulli equation (ΔP = 1 / 2 ρv 2The conversion efficiency of fluid kinetic energy to pressure energy is controlled. Initial hydrogen emulsification is achieved in the first-stage pressurization unit 302. Subsequent pressurization units 302 suppress bubble coalescence by reducing the pressure gradient (ΔP / ΔL), and combined with the shearing effect of the spiral static mixer, the hydrogen bubble size is controlled to below 100 nm. The bidirectional pressurization design of the dissolution stabilization component 4 is based on the double-film theory. Synchronous gas supply from the upper and lower ends forms a concentration gradient field, increasing the diffusion flux of hydrogen molecules into the liquid phase (J=KmΔC). Simultaneously, the turbulent pulsations (Re>4000) generated by the eddy current generator enhance the interface renewal rate, thus improving the dissolution efficiency compared to the single-stage pressurization process.

[0062] Please refer to the following specific embodiments in this application. Figures 3-4 The electrolytic hydrogen production mechanism 2 adopts a modular integrated design, with its core consisting of a housing 201, an electrolysis unit 202, and a swirling shearing assembly 203. The housing 201 is a sealed pressure-bearing structure, internally housing the electrolysis unit 202. This unit uses a proton exchange membrane (PEM) as the diaphragm, with an iridium oxide coating on the anode catalyst layer and a platinum-carbon alloy on the cathode catalyst layer. Hydrogen is generated through a water electrolysis reaction driven by a DC power supply. At the bottom of the housing 201, the swirling shearing assembly 203 is driven by a motor 2031 to rotate a turbine 2032. The turbine blades are designed with a backward-curved surface structure, and the speed is adjustable from 500-3000 rpm. It generates an axial swirling flow field to shear and break up hydrogen bubbles. After gas-liquid separation, the hydrogen is transported to the pump group 7 via pipe A for pressurization, and then distributed to the multi-stage pressurized mixing mechanism 3 via pipe B. Simultaneously, some hydrogen is diverted to the dissolution stabilization assembly 4 via pipes D2 and D3, forming a dual-channel gas supply path.

[0063] Specifically, the design of the vortex shearing assembly 203 is based on the turbulent shearing theory and bubble dynamics principles in fluid mechanics. When the motor 2031 drives the rotating turbine 2032 to rotate at high speed, the fluid forms a forced vortex under the action of centrifugal force. According to the velocity gradient theory (G=Δv / Δy), the linear velocity at the tip of the turbine blades can reach 15m / s, generating a velocity as high as 10 at the interface. 4 s -1 The shear rate causes the hydrogen bubbles to undergo stretching, deformation, and eventual rupture, reducing the bubble diameter from an initial 50-100 μm to below 10 μm. This process significantly increases the hydrogen-water interphase area (…). (where d is the bubble diameter and d is the volume fraction) combined with the high-purity hydrogen (purity ≥ 99.99%) generated by the PEM electrolysis unit 202, providing a micron-level gas source for subsequent multi-stage pressurized mixing. The dual-channel gas supply path achieves gradient supply of hydrogen in the mixing mechanism 3 and the dissolution component 4 through the diversion design of pipe B and pipes D2 / D3, avoiding the impact of single-channel pressure fluctuations on system stability.

[0064] It should be noted that in the above scheme: as Figure 8

[0065] (1) The rotational flow shear is strengthened: the rotational flow shear component 203 reduces the hydrogen bubble particle size to sub-millimeter level, combined with the high purity gas production characteristics of the PEM electrolysis unit 202, the hydrogen dissolution resistance in the pipeline is reduced by 42%, and the delivery efficiency is significantly improved;

[0066] (2) Energy efficiency optimization: the shear work of the rotational flow shear component 203 accounts for only 8% of the total power consumption of the system, but the hydrogen solubility is increased by 1.8 times, and the energy consumption per unit of hydrogen production is reduced to 0.35 kWh / Nm 3 , which is 27% lower than that of the traditional electrolytic hydrogen production system. This design is particularly suitable for altitudes above 3000 meters, and can overcome the problem of hydrogen escape caused by low pressure environment, and ensure that the hydrogen concentration of hydrogen-rich water is stable above 1.2ppm.

[0067] In some embodiments of the present application, please refer to Figures 5-7 : The multi-stage pressurization mixing mechanism 3 adopts a vertical series structure design, and its core is composed of a container 301, a pressurization unit 302 and a microporous dispersion unit 303. The container 301 is a cylindrical pressure-bearing container, the upper part is connected with the external water body through a water inlet pipe, and a plurality of pressurization units 302 are connected in series from bottom to top inside. The bottom pressurization unit 302 is provided with a normal pressure mixing chamber, and a gas-liquid mixing pump 3022 is arranged in the chamber. The pump adopts a centrifugal impeller structure, and the rotating speed can be adjusted in the range of 500-1500 rpm. The pump sucks hydrogen and water through negative pressure and preliminarily mixes them. After the hydrogen is dispersed by the titanium alloy microporous plate (pore size 50μm) of the microporous dispersion unit 303, it enters the pressure chamber 3021 of the bottom pressurization unit 302, and forms a rotational flow mixing state under the action of the gas-liquid mixing pump 3022. The pressure chambers 3021 of the upper pressurization units 302 are pressurized step by step, and the pressurization ratio of each stage is set to 0.2MPa. By adjusting the rotating speed and impeller angle of the gas-liquid mixing pump 3022, the forced dissolution of hydrogen in the high-pressure environment is realized. Finally, the preliminarily prepared hydrogen-rich water is pumped by the pump group 7 through pipe C, and is transported to the dissolution stabilization component 4 through pipe D1 for deep treatment.

[0068] Specifically, the design of the mechanism is based on the coupling mechanism of gas dissolution dynamics and fluid mechanics. The microporous dispersion unit 303 cuts the hydrogen into micron-sized bubbles (d<100μm) through physical confinement effect. According to the Kelvin equation (ln(P / P0)=2γVm / (rRT)), the reduction of bubble particle size significantly improves the internal pressure (P) of the bubble, thereby strengthening the driving force of hydrogen mass transfer to the liquid phase. The pressurization unit 302 adopts a staged pressurization strategy. The mechanical energy input of the gas-liquid mixing pump 3022 in each pressure chamber 3021 converts the fluid kinetic energy into pressure energy (ΔP=1 / 2ρv 2 ​), achieving high-efficiency hydrogen dissolution in turbulent state (Re>4000). In the pressure chamber 3021 of the top pressurization unit 302, the hydrogen solubility follows Henry's law (C=kP), and the hydrogen concentration can reach 1.6 ppm under a working pressure of 0.6 MPa, which is 3 times higher than the solubility under normal pressure. The multi-stage series structure effectively suppresses the bubble coalescence phenomenon by gradually reducing the pressure gradient (ΔP / ΔL), ensuring the stability of the dissolution process.

[0069] It should be noted that in the above scheme: as shown in Figure 9 , the multi-stage pressurization mixing mechanism 3:

[0070] (1) Pressure gradient adaptation: through the design of staged pressurization, the system pressure of 0.6 MPa can still be maintained at an altitude of 4000 meters (atmospheric pressure of 62.5 kPa), making the hydrogen solubility 2.3 times higher than that of traditional single-stage pressurization equipment;

[0071] (2) Micro-bubble enhanced dissolution: the synergistic effect of the microporous dispersion unit 303 and the gas-liquid mixing pump 3022 reduces the hydrogen bubble size to microns, increases the specific surface area by 100 times, and significantly prolongs the residence time of hydrogen in water (from 15 min to 60 min);

[0072] (3) Energy efficiency optimization: the staged pressurization strategy reduces the system energy consumption to 0.45 kWh / L, saving 25% energy compared with continuous high-pressure equipment. At the same time, by adjusting the number of pressurization units 302 (3-5 stages), different pressure environments at altitudes of 2000-5000 meters can be flexibly adapted, ensuring that the hydrogen concentration of hydrogen-rich water is stable in the range of 1.2-1.6 ppm, meeting the dosage requirements of high-altitude medical and sports rehabilitation scenarios.

[0073] In some specific embodiments of the present application, please refer to Figure 7: The micro-porous dispersion unit 303 adopts a double-layer composite structure design, and its core is composed of a hole array sieve plate 3031, a water channel plate 3032, and an ultrasonic vibrator 304. The hole array sieve plate 3031 is made of titanium alloy material, and the surface is formed with a regular array of micro-holes by laser drilling technology. The hole diameter is accurately controlled within the range of 0.2-0.5 mm, and the whole sieve plate is in an arc convex structure, and the arc curvature radius is matched with the inner diameter of the container 301 to maximize the hydrogen contact area. The water channel plate 3032 is located below the sieve plate and adopts a honeycomb flow channel design with a flow channel width of 2 mm and a depth of 5 mm to ensure uniform distribution of hydrogen. The ultrasonic vibrator 304 is fixed on the edge of the sieve plate and adopts a piezoelectric ceramic transducer with a working frequency of 20 kHz and an adjustable amplitude range of 10-50 μm. During operation, hydrogen is transported to the water channel plate 3032 through pipe B, uniformly rises to the bottom of the hole array sieve plate 3031 through the honeycomb flow channel, and the high-frequency vibration generated by the ultrasonic vibrator 304 causes the sieve plate to resonate, breaks the hydrogen bubbles to micron or even nanometer level, and then enters the bottommost pressurizing unit 302 for mixing.

[0074] Specifically: the design of the unit is based on the coupling mechanism of ultrasonic cavitation effect and fluid mechanics. When the ultrasonic vibrator 304 vibrates at a frequency of 20 kHz, periodic pressure fluctuations are formed on the surface of the hole array sieve plate 3031. According to the cavitation nucleus theory (Pc = Ph + Pv - 2σ / R), when the local pressure is lower than the saturated vapor pressure of hydrogen, gas molecules gather into nuclei and rapidly expand, generating micro-jets (velocity up to 100 m / s) and shock waves (pressure up to 100 MPa), which break the hydrogen bubbles to sub-micron level. The arc design of the sieve plate causes the hydrogen to generate a radial velocity gradient when flowing through the sieve plate, according to Bernoulli's equation (ΔP = 1 / 2 ρv 2 ), the difference in flow rate causes a pressure difference, further strengthening the bubble shear effect. The sieve plate with a hole diameter of 0.2-0.5 mm forms a dynamic sieving effect under ultrasonic vibration, large-size bubbles are trapped and broken again, and small-size bubbles (d < 1 μm) pass through the sieve holes into the pressurizing unit 302, the specific surface area increases several times, and the gas-liquid contact efficiency is significantly improved.

[0075] It should be noted that in the above scheme: the micro-porous dispersion unit 303 realizes three major functional breakthroughs in the high-altitude low-pressure environment:

[0076] (1) Ultrasonic enhanced dispersion: the synergistic effect of ultrasonic vibration and arc sieve plate reduces the hydrogen bubble particle size to nanometer level, increases the specific surface area by several times, and improves the gas-liquid contact efficiency by 3 times;

[0077] (2) Pressure self-adaptive design: the matching design of sieve plate hole diameter and ultrasonic frequency (f = 0.5v / d, v is the fluid velocity, d is the hole diameter) enables the system to maintain high-efficiency dispersion at an altitude of 5000 meters (atmospheric pressure 54 kPa), and the hydrogen solubility is improved by 2.8 times compared with the traditional sieve plate;

[0078] (3) Anti-clogging performance: Titanium alloy material and honeycomb flow channel design make the screen plate still have no clogging phenomenon after 1000 hours of continuous operation, and the maintenance period is extended to 6 months, especially suitable for high-hardness water quality scenes in highland areas. The unit cooperates with the multi-stage pressurizing mixing mechanism 3 to make the hydrogen concentration of the hydrogen-rich water stable at 1.6 ppm or more, meeting the preparation requirements of medical-grade hydrogen-rich water.

[0079] In some specific embodiments of the present application, please refer to Figures 3-6 : The dissolution stability assembly 4 adopts a three-stage series structure design, and its core is composed of three sections of tank bodies with decreasing diameters (upper tank body 401, middle tank body 402, and lower tank body 403) and heat transfer pipes 8. The upper tank body 401 is connected with the pump set 7 through pipe D1 to receive the hydrogen-rich water prepared initially; the middle tank body 402 and the lower tank body 403 are connected with the pump set 7 through pipes D2 and D3 respectively to receive the hydrogen generated by the electrolytic hydrogen production mechanism 2. The three sections of tank bodies are provided with spiral guide plates inside, and the pitch of the guide plates decreases step by step from top to bottom (from 50 mm of the upper tank body 401 to 20 mm of the lower tank body 403), forcing the fluid to generate a rotating flow field. The heat transfer pipe 8 adopts a double-layer sleeve structure, the inner pipe flows the heat medium (such as heat conducting oil) generated by the heater 6, and the outer pipe is welded with the shell of the dissolution stability assembly 4 to transfer heat to the inside of the tank body through heat convection, maintaining the dissolution temperature at 40±2℃. During operation, the hydrogen-rich water and hydrogen form a three-dimensional turbulent flow (Reynolds number Re>4000) in the tank body, and the hydrogen bubbles are further broken and dissolved under the joint action of shear force and thermal motion.

[0080] Specifically: The design of this assembly is based on the principle of turbulent flow strengthening mass transfer and the mechanism of heat-assisted flow. The three sections of tank bodies with different diameters generate pressure fluctuations through flow rate changes (flow rate is inversely proportional to tank body diameter), according to the turbulent energy cascade theory, large-scale vortices are broken into small-scale vortices under the action of guide plates, and energy is transferred to molecular scale step by step, strengthening the mass transfer of hydrogen to liquid phase. The heat transfer pipe 8 transfers heat to the tank body through heat convection (q=hAΔT), which intensifies the thermal motion of hydrogen molecules (according to Maxwell's velocity distribution, the average velocity of molecules increases by 3% for every 10℃ increase in temperature), and at the same time, reduces the surface tension of water (σ∝e^(-E / RT)), promoting bubble rupture and dissolution. In addition, the three-stage gas supply path (pipes D1, D2, D3) forms a hydrogen concentration gradient field (ΔC=C_upper-C_lower), driving hydrogen molecules to diffuse to low-concentration areas, combined with the convection effect of the turbulent flow field, the dissolution rate is increased by 2.1 times.

[0081] It should be pointed out that in the above scheme: as Figure 10 shown, the dissolution stability assembly 4:

[0082] (1) Turbulent flow enhanced dissolution: The variable diameter design of the three-stage tank and the spiral guide plate cause the fluid to produce strong turbulence, and the hydrogen dissolution efficiency is increased by 45% compared to the laminar flow state, and the dissolution time is shortened to less than 15 minutes;

[0083] (2) Thermal auxiliary flow: The heating function of the heat transfer pipe 8 increases the kinetic energy of hydrogen molecules, and the bubble rupture rate is increased by 3 times, while inhibiting the decrease of solubility caused by the low temperature environment on the plateau (for every 1℃ increase in temperature, the solubility is increased by 2.3%);

[0084] (3) Multi-channel gas supply redundancy: The three-stage gas supply path enables the system to have pressure adaptive capability, and when one channel is insufficient due to low pressure on the plateau, the remaining channels can maintain more than 80% of the gas supply, ensuring that the hydrogen concentration of the hydrogen-rich water in the finished product tank 5 is stable at more than 1.6ppm. The component and the multi-stage pressurization mixing mechanism 3 work together to control the hydrogen concentration fluctuation range of the hydrogen-rich water in the finished product tank 5 to be within ±0.1ppm, meeting the dose accuracy requirements of plateau medical emergency and sports rehabilitation scenarios.

[0085] In the present scheme, all electrical components of the device as a whole rely on commercial power for energy supply; specifically, the electrical components of the device as a whole are connected to the commercial power output port through relays, transformers, and button panels, etc. to meet the energy supply requirements of all electrical components of the device.

[0086] Specifically, the device also has a controller for connecting and controlling all electrical components of the device as a whole according to the pre-set program as the preset value and driving mode; it should be noted that the driving mode corresponds to the start-stop time interval, speed, power, etc. of the corresponding electrical components in the following, that is, it meets the requirements of the related electrical components driving the related mechanical devices according to the functions described in the following.

[0087] Preferably, the controller is a PLC controller, which completes the above control requirements through conventional PLC control modes such as ladder diagram, sequential function chart, function block diagram, instruction table, or structure text; it should be noted that the start-stop time interval, speed, power, etc. of the electrical components or other power components driven by its programming are not limited; specifically, the adjustment of the related driving control is made according to the actual use requirements.

[0088] Example Two: Based on Example One, this embodiment further provides a preferred technical solution.

[0089] The electrolysis unit 202 adopts a solid polymer electrolyte (SPE) technology, the core of which is a proton exchange membrane with a thickness precisely controlled at 0.15 mm ± 0.02 mm. The membrane material is a perfluorosulfonic acid resin (such as the Nafion series), which is tightly combined with the titanium-based platinum carbon electrodes on both sides through a hot pressing process, forming a sandwich structure. During the electrolysis process, pure water is delivered to the anode chamber of the electrolysis unit 202 through pipe A of the pump set 7, and under the action of a direct current electric field, water molecules undergo an oxidation reaction at the anode catalyst layer (iridium oxide coating) to generate oxygen and protons (H + ). The protons migrate through the proton exchange membrane to the cathode chamber, where they combine with electrons at the cathode catalyst layer (platinum carbon alloy) to be reduced to hydrogen gas. The generated hydrogen gas is sheared and broken by the rotating turbine 2032 of the cyclone shearing assembly 203, and then delivered to the multi-stage pressurizing mixing mechanism 3 through pipe B, while part of the hydrogen gas is diverted to the dissolution stabilization assembly 4 through pipe D2 and pipe D3, forming a dual-channel gas supply path.

[0090] Specifically, the working principle of the SPE electrolysis unit 202 is based on electrochemical catalysis and proton conduction mechanism. The perfluorosulfonic acid proton exchange membrane as the core component, its 0.15 mm thickness design realizes the balance of proton conductivity and gas permeability. The thinner membrane layer (such as 0.13 mm) can reduce the proton migration resistance (the ohmic polarization overpotential is reduced to below 50 mV), and improve the electrolysis efficiency; while the slightly thicker membrane layer (such as 0.17 mm) can effectively prevent the penetration of oxygen to the cathode chamber (permeability <0.5%), ensuring the purity of hydrogen gas. Under the action of an electric field, the anode reaction (2H2O→O2+4H + +4e - ) and the cathode reaction (4H + +4e - →2H2) proceed synchronously, and the proton exchange membrane only allows H + to pass, forming charge balance.

[0091] In this embodiment, as shown in Figure 11 , the SPE electrolysis unit 202 exhibits three major functional advantages in high-altitude environments:

[0092] (1) High-efficiency hydrogen production: The 0.15 mm proton exchange membrane increases the electrolysis efficiency to more than 85%, and the energy consumption per unit of hydrogen production is reduced to 0.35 kWh / Nm 3 , which is 30% lower than traditional alkaline electrolysis tanks;

[0093] (2) Environmental adaptability: The dual-channel gas supply path design enables the system to have pressure self-adaptability. When the plateau environment causes pressure fluctuations in one channel, the other channel can maintain more than 70% of the gas supply, ensuring the stability of the dissolution. This unit is particularly suitable for altitudes above 4000 meters. It can overcome the problem of hydrogen escape caused by low pressure environment, ensure that the hydrogen concentration of hydrogen-rich water is stable at 1.2 ppm or more, and meet the preparation needs of medical-grade hydrogen-rich water.
