[0042] The present application provides a hydrogen-rich water preparation device, thereby solving the problem that in the existing hydrogen-rich water preparation equipment, the hydrogen content in the hydrogen-rich water flowing out is relatively low when hydrogen is directly introduced into water.

[0043] Reference is made below to Figures 1 to 10 describe the hydrogen-rich water preparation device according to some embodiments of the present application.

[0044] As Figure 1 and Figure 2 shown, the hydrogen-rich water preparation device of the present application includes a jet pump 100, a hydrogen mixing pump 200 and a cutting pipe 300 that are connected in sequence. Among them, as Figure 6 shown, the jet pump 100 includes a main pipe and a hydrogen suction pipe 103 that communicate with each other; the fluid entering the main pipe can suck in hydrogen from the hydrogen suction pipe 103 and flow out of the jet pump 100; a rotating blade mechanism 301 is provided in the cutting pipe 300; after the fluid flows out through the jet pump 100, it enters the hydrogen mixing pump 200 for pressurization, and the fluid after passing through the hydrogen mixing pump 200 enters the cutting pipe 300 and is disturbed and sheared by the blade mechanism 301.

[0045] The fluid of the present application flows through the ejector 100, the hydrogen mixing pump 200, and the cutting pipe 300 in sequence. First, the working water absorbs hydrogen and mixes with hydrogen in the ejector 100 to form hydrogen-rich water. After that, the hydrogen-rich water flowing out of the ejector 100 is pressurized by the hydrogen mixing pump 200, that is, the hydrogen-rich water and hydrogen in the cavity of the hydrogen mixing pump 200 are continuously pressurized. Under high-pressure conditions, hydrogen dissolves better in water to form supersaturated hydrogen-rich water. Finally, the supersaturated hydrogen-rich water flowing out of the hydrogen mixing pump 200 undergoes turbulence and shearing in the cutting pipe 300, that is, the blade mechanism 301 in the cutting pipe 300 subjects the high-speed moving gas-liquid to turbulence and shearing using the blades, turning the hydrogen bubbles in the water into uniform nano-scale small bubbles and cutting the small molecular clusters into monomer water molecules. In this way, hydrogen can be evenly dissolved between water molecules, greatly increasing the solubility of hydrogen in water and forming supersaturated hydrogen-rich water.

[0046] In summary, for the hydrogen-rich water preparation device of the present application, after water and hydrogen pass through the ejector 100, the hydrogen mixing pump 200, and the cutting pipe 300 in sequence to absorb and mix hydrogen, the hydrogen-rich water flowing out thereof has a high hydrogen content.

[0047] In the first example of the present application, as Figure 1 and Figure 2 shown, the water inlet of the hydrogen mixing pump 200 is connected to the water outlet of the ejector 100 through the first connecting pipe 201, the water outlet of the hydrogen mixing pump 200 is connected to the water inlet of the cutting pipe 300 through the second connecting pipe 202, and a blade mechanism 301 is provided in the cutting pipe 300; after the working water flows out of the ejector 100, the mixed saturated hydrogen-rich water and hydrogen enter the hydrogen mixing pump 200 to be pressurized, and the saturated hydrogen-rich water and hydrogen after passing through the hydrogen mixing pump 200 enter the cutting pipe 300 and are subjected to turbulence and shearing by the blade mechanism 301.

[0048] Specifically: The saturated hydrogen-rich water and hydrogen mixed with hydrogen in the ejector 100 enter the pressurizing pump (i.e., the hydrogen mixing pump 200). In the cavity of the pressurizing pump, the hydrogen-rich water and hydrogen are continuously pressurized. Under high-pressure conditions, according to the gas law PV = nRT, with the temperature T and volume V remaining unchanged and R being a constant, the greater the pressure P, the more hydrogen dissolves in water, causing the gas-liquid mixed water to rotate, collide, and shear at high speed in the cavity, cutting the large molecular cluster water into small molecular clusters and turning the large bubble hydrogen in the water into microbubble hydrogen, enabling more hydrogen molecules to dissolve into water molecules to form supersaturated hydrogen-rich water.

[0049] The supersaturated hydrogen-rich water with microbubbles and hydrogen produced by the action of a pressure pump (i.e., the hydrogen mixing pump 200) enters the secondary pressure hydrogen dissolution module (i.e., the cutting pipe 300). In the special structure of the secondary pressure hydrogen dissolution module, through the combination of the blade mechanism and the needle valve, the high-speed moving gas-liquid is used to turn the large hydrogen bubbles and ultramicrobubble hydrogen in the water into uniform nanoscale small bubbles by means of the impact, turbulent flow, eddy current, and shear force of the impeller. The small molecular clusters are cut into monomer water molecules, and a monomer water molecule is composed of one water molecule. Monomer water molecules have the characteristics of strong activation, strong penetration, strong solubility, strong diffusion, strong detergency, and weak alkalinity compared with small molecular cluster water and large molecular cluster water. Hydrogen can be evenly dissolved between water molecules, greatly increasing the solubility of hydrogen in water, forming supersaturated hydrogen-rich water in a water-in-gas state. The uniform nano hydrogen bubbles are not easily aggregated into large hydrogen bubbles and can dissolve and stay in water for several days or even months.

[0050] According to Stokes' equation, the rising rate of bubbles in water is as follows:

[0051] V = 2r 2 (Δp)g / 9η, where V is the rising rate of the bubble, Δp is the difference between the density of hydrogen and the density of water, η is the fluid viscosity, which is the viscosity of water, r is the radius of hydrogen, and g is the acceleration due to gravity. The smaller the bubble size, the smaller the rising rate of the bubble, and the longer its residence time in water. Therefore, the hydrogen-rich water containing hydrogen nano bubbles can not only increase the solubility of hydrogen in water but also extend the dissolution time of hydrogen.

[0052] Water is a polar molecule, that is, one end is negatively charged and the other end is positively charged. The positive and negative ends of water molecules attract each other and are connected together to form water molecule clusters. Large molecular cluster water is generally composed of 12 water molecules, and small molecular cluster water is generally composed of 6 water molecules. Since hydrogen can only be dissolved into the gaps between water molecule clusters, the gas solubility of ordinary water molecule cluster water is low. For monomer water molecules, gas can be evenly dissolved between water molecules, greatly increasing the gas solubility in water.

[0053] As an example, as Figure 8 shown, a first pressure maintaining pipe 302 and a second pressure maintaining pipe 303 are also arranged in the cutting pipe 300. Among them, the blade mechanism 301 is arranged between the first pressure maintaining pipe 302 and the second pressure maintaining pipe 303; the blade mechanism 301 includes a blade shaft and blades arranged on the outer periphery of the blade shaft. The outer walls of the first pressure maintaining pipe 302 and the second pressure maintaining pipe 303 are attached to the inner wall of the cutting pipe 300, and there is a certain gap between the blade mechanism 301 and the inner wall of the cutting pipe 300.

[0054] As Figure 9 and Figure 10As shown in the figure, one end of the first pressure-holding pipe 302 facing the second pressure-holding pipe 303 is provided with a water outlet hole 3021, and the other end of the first pressure-holding pipe 302 is provided with a water inlet; one end of the second pressure-holding pipe 303 facing the first pressure-holding pipe 302 is provided with a water inlet hole 3031, and the other end of the second pressure-holding pipe 303 is provided with a water outlet. The fluid entering the cutting pipe 300 sequentially passes through the first pressure-holding pipe 302, the blade mechanism 301, and the second pressure-holding pipe 303, and flows out from the water outlet of the second pressure-holding pipe 303.

[0055] In this way, the water outlet hole 3021 of the first pressure-holding pipe 302 facing the second pressure-holding pipe 303 and the water inlet hole 3031 of the second pressure-holding pipe 303 facing the first pressure-holding pipe 302 have small apertures. On the one hand, the pressure between the first pressure-holding pipe 302 and the second pressure-holding pipe 303 can be ensured, so that the blade mechanism 301 can rotate at a high speed; on the other hand, the pressure between the first pressure-holding pipe 302 and the second pressure-holding pipe 303 can be ensured to increase the amount of dissolved hydrogen.

[0056] Furthermore, the hydrogen-rich water preparation device further includes a needle valve; the needle valve is arranged between the water outlet of the hydrogen mixing pump and the water inlet of the cutting pipe. In this way, the flow rate or pressure inside the cutting pipe (between the first pressure-holding pipe and the second pressure-holding pipe) can be controlled by adjusting the needle valve.

[0057] It is worth mentioning here that the hydrogen-rich water preparation device in the first example has a simple structural water path and few components.

[0058] In the second example of the present application, as Figure 7 shown, the hydrogen-rich water preparation device may further include a mixing three-way valve 400 and a solenoid valve 500. Among them, the three-way valve 400 includes a water inlet, a pure water outlet, and a hydrogen-rich water outlet. The water inlet of the ejector 100 is communicated with the hydrogen-rich water outlet, the water inlet of the hydrogen mixing pump 200 is communicated with the water outlet of the ejector 100 through a first connecting pipe 201, and the water outlet of the hydrogen mixing pump 200 is communicated with the water inlet of the cutting pipe 300 through a second connecting pipe 202. The water inlet of the solenoid valve 500 is communicated with the pure water outlet through a third connecting pipe 401, and the water outlet of the solenoid valve 500 is communicated with the cutting pipe 300 (for example, as Figure 8 shown, the water outlet of the solenoid valve 500 is communicated with a third pressure-holding pipe 304 through a fourth connecting pipe 402. Both the water inlet and the water outlet of the third pressure-holding pipe 304 are large-diameter openings).

[0059] When the solenoid valve 500 is opened (i.e., when pure water is prepared), the working water flows through the pure water outlet, enters the solenoid valve 500, and flows out from the water outlet of the cutting pipe 300.

[0060] When the solenoid valve 500 is closed (i.e., when preparing hydrogen-rich water), the working water flows through the hydrogen-rich water outlet and then enters the ejector 100. After flowing out of the ejector 100, the mixed saturated hydrogen-rich water and hydrogen enter the hydrogen mixing pump 200 to be pressurized. The saturated hydrogen-rich water and hydrogen after passing through the hydrogen mixing pump 200 enter the cutting pipe 300 to be pressurized, and are turbulently flowed and sheared by the blades. It should be noted here that the principle when preparing hydrogen-rich water is the same as that of the first example.

[0061] It is worth mentioning here that in the hydrogen-rich water preparation device under the second example, the two water paths for discharging hydrogen-rich water and pure water are separated. When hydrogen-rich water needs to be discharged, the hydrogen mixing pump 200 is started and the solenoid valve 500 is closed. When pure water needs to be discharged, the solenoid valve 500 is opened and the hydrogen mixing pump 200 is closed (and the blades of the cutting pipe 300 are closed), effectively prolonging the life of the pump and not affecting the water use experience.

[0062] In addition, regardless of which two examples of the hydrogen-rich water preparation device, it saves structural space, is convenient for assembly, and saves labor costs.

[0063] Next, the ejector and the design method of the ejector described in some embodiments of the present application will be referred to Figures 1 to 7 and described.

[0064] As Figure 5 and Figure 6 shown, the ejector 100 of the present application includes a conduit 101, a throat pipe 102, and a hydrogen suction pipe 103. Among them, the conduit 101 and the throat pipe 102 extend along a first direction L1, the hydrogen suction pipe 103 extends along a second direction L2, and the first direction L1 and the second direction L2 intersect (for example, are perpendicular); the conduit 101 and the throat pipe 102 are respectively arranged on both sides of the hydrogen suction pipe 103, and the conduit 101 is communicated with the hydrogen suction pipe 103 through its nozzle 1011, and the throat pipe 102 is communicated with the hydrogen suction pipe 103 through its throat nozzle 1021. It should be noted here that the wall thickness at each position of the ejector 100 of the present application is different, and the above-mentioned conduit 101, throat pipe 102, and hydrogen suction pipe 103 refer to the cavities inside each position of the ejector 100.

[0065] The design method of the ejector 100 includes:

[0066] D 2 = 4Q * 1000 / [3.6 * π * φ(2gH) 1 / 2 ; where D is the diameter of the nozzle 1011, Q is the flow rate of hydrogen-dissolved water, φ is the nozzle flow velocity coefficient, g is the acceleration, and H is the nozzle pressure.

[0067] Gs = u * V * L / η; where Gs is the hydrogen inhalation amount, u is the TDS value of pure water, V is the inlet water flow velocity, L is the amount of hydrogen required to float 1 gram of absolutely dry solid matter, and η is the dissolution efficiency of hydrogen in water.

[0068] Q = Gs / (L 2 - L 1 )); where L 2 and L 1 are the dissolved amounts of hydrogen in water at different pressures under a fixed temperature; where V = 1 - 3 L / min.

[0069] Based on the above design method, it can be known that D = KV, and thus the relationship between D and V can be known. In this way, when V takes 1 L / min, 2 L / min, or 3 L / min, the corresponding values of D can be known.

[0070] After knowing the size of D, those skilled in the art can design the structural dimensions of the ejector 100 according to requirements (the diameter D of the nozzle 1011, or the dimensions and relationships of the throat tube 102 and the hydrogen suction tube 103). Finally, after the structural dimensions of the ejector 100 are designed, it is subjected to experimental tests. The test results show that the hydrogen content in the hydrogen-rich water flowing out is relatively high, reaching more than 1600 ppb.

[0071] In the embodiment of the present application, the design concept and specific design method of the ejector 100 are as follows:

[0072] As Figure 6 shown, the ejector 100 mainly consists of several key structures such as a conduit 101 (nozzle 1011), a throat tube 102 (throat tube orifice 1021), a drainage tube 104, and a hydrogen suction tube 103. Its core structures are the nozzle 1011 and the throat tube orifice 1021. In the household hydrogen-rich water machine system, the working pressure of the ejector 100 is generally 5 - 40 psi. The working water flow is continuously pressurized and accelerated in the conduit 101 and then ejected at a high speed from the nozzle 1011, forming a negative pressure in the surrounding air chamber to suck in a large amount of hydrogen. A large amount of hydrogen is carried by the high-speed water column and rushes into the throat tube 102 at a high speed. In the first half of the throat tube 102, hydrogen and water are violently mixed and cut into bubbles, and hydrogen can dissolve into the gaps between water molecule clusters. In the second half, hydrogen is close to atomization, forming saturated hydrogen-rich water.

[0073] The determination of the key components of the ejector plays a decisive role in the working efficiency of the ejector and also plays a crucial role in the hydrogen absorption efficiency of the hydrogen-rich water. Therefore, the ejector 100 with this hydrogen absorption structure is designed as follows.

[0074] (1) Design formula for the diameter of the nozzle 1011:

[0075] D 2 = 4Q * 1000 / [3.6 * π * φ(2gH) 1 / 2, where D is the diameter of the nozzle 1011, Q is the flow rate of hydrogen-dissolved water, φ is the velocity coefficient of the nozzle 1011 (0.95 - 0.975, taking 0.95 here), g is the acceleration (taking 9.8 m / s, 588 m / min here), and H is the pressure of the nozzle 1011 (taking 4 kg / cm 2 ).

[0076] That is, D 2 = 5.68 * Q;

[0077] (2) Calculation formula for the flow rate of hydrogen-dissolved water:

[0078] Gs = u * V * L / η, where Gs is the hydrogen inhalation amount, u is the TDS value of pure water (generally 0.005 - 0.02 g / L, taking 0.01 g / L here), V is the inlet water flow velocity, L is the hydrogen amount required to float 1 gram of absolutely dry solid matter (generally 0.14 - 0.35 L, taking 0.25 L here), and η is the hydrogen dissolution efficiency in water (generally 25% - 35%, taking 25% here). That is, Gs = 0.01V.

[0079] Q = Gs / (L 2 - L 1 ) where L 1 is the hydrogen dissolution amount in water at a pressure of 0 kg / cm 2 , L 1 takes 18 ml / L, L 2 is the hydrogen dissolution amount in water at a pressure of 4 kg / cm 2 , L 2 takes 73 ml / L (L 2 is approximately equal to 73 ml / L), that is, Q = 0.18V, D = (1.0224V) 1 / 2 .

[0080] Here, the pressure value can be selected according to the structure of the ejector itself (such as the wall thickness of the ejector).

[0081] (3) Design formula for the diameter of the throat tube 102:

[0082] where D is the diameter of the nozzle 1011 and d is the diameter of the throat tube orifice 1021.

[0083] (4) Design formula for the length of the throat tube:

[0084] A = K * d (mm), where K takes 5 and A is the length of the throat tube 102.

[0085] (5) Design formula for the distance between the nozzle 1011 and the throat tube 102:

[0086] B = 0.5d (mm), where B is the distance from the nozzle 1011 to the throat nozzle 1021.

[0087] (6) Design formula for the diameter of the hydrogen absorption tube 103:

[0088] C = a * d (mm), where a is taken as 0.7 and C is the diameter of the hydrogen absorption tube 103.

[0089] In summary, after the structural dimensions of the ejector 100 are designed by those skilled in the art and then tested, the test results show that the hydrogen content in the hydrogen-rich water flowing out is relatively high, reaching more than 1600 ppb. The specific test data are as follows in the table:

[0090]

[0091] As can be seen from the above table, when the inlet water flow rate is 1 L / min, the diameter of the nozzle 1011 is 1.01 mm, the diameter of the throat nozzle 1021 is 1.43 mm, the length of the throat tube 102 is 7.14 mm, the distance from the nozzle 1011 to the throat nozzle 1021 is 0.72 mm, and the diameter of the hydrogen absorption tube 103 is 1 mm.

[0092] When the inlet water flow rate is 2 L / min, the diameter of the nozzle 1011 is 1.43 mm, the diameter of the throat nozzle 1021 is 2.02 mm, the length of the throat tube 102 is 10.11 mm, the distance from the nozzle 1011 to the throat nozzle 1021 is 1.01 mm, and the diameter of the hydrogen absorption tube 103 is 1.414 mm.

[0093] When the inlet water flow rate is 3 L / min, the diameter of the nozzle 1011 is 1.75 mm, the diameter of the throat nozzle 1021 is 2.47 mm, the length of the throat tube 102 is 12.37 mm, the distance from the nozzle 1011 to the throat nozzle 1021 is 1.23 mm, and the diameter of the hydrogen absorption tube 103 is 1.73 mm.

[0094] The solubility of hydrogen is 1.83%, which is converted to the mass of 1 liter of water. Under standard conditions, the maximum amount of dissolved hydrogen is 1.6 mg, and the conversion amount of 1.6 mg / L is 1.6 ppm, and 1 ppm = 1000 ppb = 1000 μg / L.

[0095] As can be seen from the above table, the test results of this application show that no matter what the inlet water flow rate of the whole machine is set to, this application can design the corresponding size of the ejector 100 so that the hydrogen content in the hydrogen-rich water flowing out of the ejector 100 reaches more than 1600 ppb.

[0096] In summary, the preparation of hydrogen-rich water in this application includes the following three modules:

[0097] Module 1: Hydrogen suction and mixing module of the ejector 100, that is, through the design of the structural parameters of the ejector 100, the hydrogen content in the hydrogen-rich water flowing out of the ejector 100 is relatively high, reaching more than 1600 ppb.

[0098] Module 2: Primary pressurization and hydrogen dissolution module, that is, the hydrogen-rich water flowing out of the ejector 100 is subjected to primary pressurization and hydrogen dissolution cutting by the hydrogen mixing pump 200.

[0099] Module 3: Secondary pressurization and hydrogen dissolution cutting module, that is, after the primary pressurization and hydrogen dissolution module, it is further subjected to secondary pressurization and hydrogen dissolution and bubble cutting by the cutting pipe 300, so that the hydrogen content in the hydrogen-rich water finally flowing out of the cutting pipe 300 can reach more than 3000 ppb.
