Description

Technical Field

[0001] The present invention relates to the field of water making machines, and in particular to a hydrogen mixing device and a high hydrogen concentration hydrogen-rich water making machine. Background Art

[0002] In recent years, as people's demand for healthy drinking water continues to increase, hydrogen-rich water has shown important application value in the fields of medical care, sports rehabilitation, etc. due to its unique antioxidant and biological activity. As a new type of healthy drinking water, hydrogen-rich water is believed to have a variety of health benefits, such as anti-fatigue, anti-inflammation, anti-radiation, anti-allergy, improving physical functions, relieving fatigue, delaying aging, etc., and has attracted the attention and recognition of consumers.

[0003] In the medical field, studies have found that hydrogen molecules can play a selective antioxidant role, effectively remove free radicals, reduce the damage of oxidative stress to the body, and regulate the immune system and metabolic function. At the same time, it has now been proven that hydrogen has a wider range of biological functions, such as improving energy metabolism and reducing cell apoptosis. It can induce the expression of antioxidant-related enzymes and reduce inflammatory responses by downregulating the expression of a series of pro-inflammatory factors. A large number of medical studies have shown that hydrogen-rich water can help relieve symptoms and enhance the therapeutic effect in the fields of metabolic diseases (such as hypertension, diabetes, hyperuricemia, hyperlipidemia, chronic constipation, gastrointestinal diseases, etc.), inflammatory diseases (such as prostatitis, superficial gastritis, arthritis, etc.), degenerative diseases (such as cardiovascular and cerebrovascular diseases, stroke recovery period), stone diseases, gynecological diseases, etc., by improving microcirculation, reducing inflammatory responses, and promoting tissue repair.

[0004] Existing hydrogen-rich water production equipment mainly realizes the dissolution of hydrogen in water through a gas-liquid mixing device. Its basic principle can be summarized as: maintaining the gas-liquid contact environment through a pressure regulating system, and promoting the dissolution of hydrogen molecules by means of mechanical stirring, bubbling diffusion or jet mixing. For example, in the patent with publication number CN220618554U and invention name "a new type of hydrogen mixer", the hydrogen-rich water flow in the mixing box is horizontally cut by setting a mixing and cutting component to cut the bubbles in the hydrogen-rich water and increase the amount of hydrogen dissolved in water.

[0005] The traditional hydrogen mixing technology has the following technical bottlenecks: First, the gas-liquid contact area is limited. The millimeter-level bubbles produced by the conventional bubbling method have a small specific surface area, resulting in insufficient effective hydrogen dissolution rate; second, the contradiction between turbulence intensity and residence time in the dynamic mixing process is difficult to reconcile. Although high-speed stirring can enhance mass transfer, it shortens the gas-liquid contact time, while low-speed mixing easily leads to two-phase separation; third, the synergy between pressure regulation and structural design is insufficient. Most existing equipment adopts a single boosting mode, which fails to achieve dynamic adaptation of pressure gradient and mixing structure. It is particularly noteworthy that the existing hydrogen mixers mostly adopt a Venturi tube structure or a simple impeller design, which has obvious defects in hydrogen nano-sizing and multiphase flow field optimization.

[0006] Therefore, developing a new type of hydrogen mixing device with efficient mass transfer characteristics, low energy consumption and strong adaptability has become a key breakthrough in improving the quality of hydrogen-rich water and the economy of equipment. Summary of the invention

[0007] In view of the above problems, the present invention proposes the following technical solutions:

[0008] A hydrogen mixing device for enhancing the effect of hydrogen molecules dissolving in water, comprising a first hydrogen mixer;

[0009] The first hydrogen mixer body is a hollow structure, with the first hydrogen mixer water inlet and the first hydrogen mixer water outlet at the two ends respectively, and the end of the first hydrogen mixer water inlet is a spray hole; a hydrogen mixing column is arranged in the first hydrogen mixer body, and the hydrogen mixing column is a hollow structure, and there is a gap space between the hydrogen mixing column and the first hydrogen mixer water inlet; the hydrogen bubble water entering from the first hydrogen mixer water inlet is injected into the hydrogen mixing column, and after colliding with the inner wall of the hydrogen mixing column, a part of it flows out from the first hydrogen mixer water outlet, and the other part returns to the gap space.

[0010] Furthermore, the size of the injection hole is 0.6 mm.

[0011] Furthermore, a plurality of grooves and protrusions are provided on the outer wall of the hydrogen mixing column.

[0012] Furthermore, it also includes a second hydrogen mixer, which is connected in series after the first hydrogen mixer;

[0013] The second hydrogen mixer body is a hollow structure, with a second hydrogen mixer water inlet and a second hydrogen mixer water outlet at both ends. Inside the second hydrogen mixer body, a stainless steel sintered high-pressure gas filter and a corrugated steel wire mesh are arranged in sequence along the direction of water flow.

[0014] Furthermore, the end of the water inlet of the second hydrogen mixer is a tapered pipe.

[0015] Furthermore, the thinnest part of the end of the water inlet of the second hydrogen mixer is a circular hole with a diameter of 1 mm.

[0016] Furthermore, the pore size of the stainless steel sintered high-pressure gas filter is 0.2 μm.

[0019] The third hydrogen mixer body is a hollow structure, with a third hydrogen mixer water inlet and a third hydrogen mixer water outlet at two ends respectively; inside the third hydrogen mixer body, a filter screen and a throttling orifice plate are arranged in sequence along the direction of water flow.

[0020] The present invention also provides a high hydrogen concentration hydrogen-rich water making machine, which uses the above-mentioned hydrogen mixing device to enhance the hydrogen mixing effect of hydrogen-rich water.

[0021] Beneficial effects: The present invention uses a three-stage hydrogen mixer. In the first hydrogen mixer, the injection hole design allows the water flow to circulate partially and collide violently to avoid the aggregation of hydrogen bubbles; the groove / protrusion structure enhances the shear force and eliminates the van der Waals force of the interaction between hydrogen molecules in hydrogen, providing a more uniform distribution basis for hydrogen molecules for subsequent treatment. In the second hydrogen mixer, the uniform distribution of hydrogen molecules in the previous stage treatment makes the load of the stainless steel sintered high-pressure gas filter balanced to avoid blockage; the water flow is accelerated and combined with the stainless steel sintered high-pressure gas filter to form a dynamic pressure oscillation field, which enhances the mixing efficiency of hydrogen molecules. In the third hydrogen mixer, the pressure gradient design (pre-stage high pressure → final stage voltage stabilization) is further used to form a dissolution equilibrium forward drive, and the Le Chatelier principle is used to promote the conversion of hydrogen molecules to a dissolved state. The three work together to produce a better hydrogen mixing effect. The hydrogen concentration of the hydrogen-rich water machine using the hydrogen mixer in the present invention can reach 5000+ppb.

DETAILED DESCRIPTION

[0032] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figures 1 to 9 As shown, a hydrogen mixing device is used to enhance the hydrogen mixing effect of hydrogen-rich water, including a first hydrogen mixer, a second hydrogen mixer, and a third hydrogen mixer connected in series in sequence, wherein the first hydrogen mixer, the second hydrogen mixer, and the third hydrogen mixer can produce a hydrogen mixing effect when used alone, but after the three are connected in series in the order of the present invention, they can work together to produce a better hydrogen mixing effect.

[0034] The first hydrogen mixer body 14 is a hollow structure, and the two ends are respectively a first hydrogen mixer water inlet 11 and a first hydrogen mixer water outlet 12, and the end of the first hydrogen mixer water inlet 11 is a spray hole; in this embodiment, the first hydrogen mixer water inlet 11 is arranged on the inlet end cover, and the inlet end cover is connected to the first hydrogen mixer body 14 by threads, and the inlet end cover and the first hydrogen mixer body 14 are sealed by a sealing ring 4; a hydrogen mixing column 13 is arranged in the first hydrogen mixer body 14, and the hydrogen mixing column 13 is a hollow structure, and there is a gap space between the hydrogen mixing column 13 and the first hydrogen mixer water inlet 11; the hydrogen bubble water entering from the first hydrogen mixer water inlet 11 is injected into the hydrogen mixing column 13, and after colliding with the inner wall of the hydrogen mixing column 13, a part of the hydrogen bubble water flows out from the first hydrogen mixer water outlet 12, and the other part returns to the gap space.

[0035] In this embodiment, the size of the injection hole is 0.6 mm; in a further embodiment, a plurality of grooves and protrusions are provided on the outer wall of the hydrogen mixing column 13, and the groove / protrusion structure is used to enhance the shear force, eliminate the van der Waals force between hydrogen molecules in the hydrogen gas, make the hydrogen molecules better dissolved in water, and further increase the hydrogen mixing effect.

[0036] In this stage of hydrogen mixer, water flows through the 0.6mm injection hole at the end to form a high-speed jet. According to the Bernoulli principle, a negative pressure zone is formed in the gap space. Part of the hydrogen bubble water coming out of the hydrogen mixing column 13 returns to the gap space. In this process, this part of the hydrogen bubble water collides between the outer wall of the hydrogen mixing column 13 and the inner wall of the first hydrogen mixer body 14, collides with the groove and convex structure of the outer wall of the hydrogen mixing column 13, and generates turbulence. Then it returns to the inside of the hollow hydrogen mixing column 13 again and collides with the inner wall for the second time. The hydrogen bubbles are broken by the impact kinetic energy, forming hydrogen molecules and prolonging the gas-liquid contact time.

[0037] The second hydrogen mixer body 23 is a hollow structure, with a second hydrogen mixer water inlet 21 and a second hydrogen mixer water outlet 22 at both ends. Inside the second hydrogen mixer body 23, a stainless steel sintered high-pressure gas filter 24 and a corrugated steel wire mesh 25 are arranged in sequence along the direction of water flow; the weaving density of the corrugated steel wire mesh 25 is 200 meshes.

[0038] In a further embodiment, the end of the second hydrogen mixer water inlet 21 is a tapered tube and the thinnest part of the end is a circular hole with an aperture of 1 mm; the pore size of the stainless steel sintered high-pressure gas filter 24 is 0.2 μm.

[0039] In this stage of hydrogen mixer, the converging pipe accelerates the water flow, and the accelerated water flow passes through the stainless steel sintered high-pressure gas filter (0.2μm pores) to form a dynamic pressure oscillation field, which enhances the mixing effect of hydrogen molecules in water. When the water flows through the wavy steel wire mesh, due to the guidance of the wavy structure and the effect of turbulence, a periodic compression-expansion effect will be produced, which further promotes gas-liquid mass transfer and enhances the effect of hydrogen molecules dissolving in water.

[0040] The third hydrogen mixer body is a hollow structure, and the two ends are respectively a third hydrogen mixer water inlet 31 and a third hydrogen mixer water outlet 32; in this embodiment, the third hydrogen mixer water inlet 31 and the third hydrogen mixer water outlet 32 ​​are arranged on the inlet end cover and the outlet end cover, and the inlet end cover and the outlet end cover are connected to the third hydrogen mixer body by threads, and the inlet end cover, the outlet end cover and the third hydrogen mixer body are sealed by a sealing ring 4; in the third hydrogen mixer body, a filter screen 33 and a throttling orifice plate 34 are arranged in sequence along the direction of water flow.

[0041] In this stage of the hydrogen mixer, the filter intercepts residual large-particle bubbles, and the throttling orifice plate induces turbulent kinetic energy dissipation through the sudden expansion flow channel design, which reduces the fluid kinetic energy while maintaining the system back pressure to prevent the hydrogen molecules dissolved in water from escaping.

[0042] In the above-mentioned three-stage hydrogen mixer, the function of the first hydrogen mixer is turbulent collision and primary dispersion, the function of the second hydrogen mixer is ultra-fine filtration and dynamic shearing, and the function of the third hydrogen mixer is pressure regulation and stable output. Specifically, in the first hydrogen mixer, the injection hole design allows the water flow to circulate partially and collide violently to avoid the aggregation of hydrogen bubbles; the groove / protrusion structure enhances the shear force and eliminates the van der Waals force of the interaction between hydrogen molecules in hydrogen, providing a more uniform distribution basis for hydrogen molecules for subsequent treatment. In the second hydrogen mixer, the uniform distribution of hydrogen molecules in the front stage treatment makes the load of the stainless steel sintered high-pressure gas filter balanced to avoid blockage; the accelerated water flow and the stainless steel sintered high-pressure gas filter form a dynamic pressure oscillation field to enhance the mixing efficiency of hydrogen molecules. In the third hydrogen mixer, the pressure gradient design (front stage high pressure → final stage pressure stabilization) is further used to form a dissolution equilibrium forward drive, and the Le Chatelier principle and Henry's law are used to promote the transformation of hydrogen molecules to the dissolved state. The three work together to produce a better hydrogen mixing effect. The formula of Henry's law is:

[0043]

[0044] in, is the gas concentration, is the partial pressure, is Henry's constant.

[0045] The three-stage hydrogen mixer in the hydrogen mixing device can produce hydrogen-rich water with different concentrations by combining different hydrogen mixers. The specific test data are as follows:

[0046] Serial number The first hydrogen mixer The second hydrogen mixer The third hydrogen mixer Concentration (ppb) 1 1 0 0 2000 2 0 1 0 1500 3 0 0 1 2000 4 1 1 1 5000 5 1 0 2 5000

[0047] Note: 0, 1, 2 represent the number of corresponding hydrogen mixers used.

[0048] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
