Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen-rich water production, in particular to a hydrogen permeation method hydrogen mixing and hydrogen dissolving pipe. Background Art

[0002] In the prior art, in the technical solution of a Chinese patent document (publication number: CN211971866U, patent name: an integrated hydrogen-rich water production device), it is disclosed that "it includes a hydrogen production device and a mixing device. The hydrogen production device is connected to the mixing device. The mixing device includes a first shower hose, a second shower hose, a water pump and a mixer. The first shower hose is connected to the water pump, the mixer is connected to the second shower hose. The mixer is provided with a mixing chamber, and a nozzle is arranged in the mixing chamber. The nozzle is connected to the water pump, and the mixing chamber is connected to the hydrogen production device through a gas supply pipe; the hydrogen production device includes a hydrogen production module and a water storage tank. The hydrogen production module is connected to the water storage tank through a water supply pipe. The hydrogen production module is provided with a first air outlet and a second air outlet. The first air outlet is connected to the mixing chamber, and the second air outlet is connected to the water storage tank; a filter screen, a bubbler and an atomizing nozzle are arranged in the second shower hose."

[0003] Combined with the description content and the attached drawings of this patent document, hydrogen is introduced into the mixer, and then through the action of the water pump, pure water is introduced into the mixer through the first shower hose. Hydrogen and pure water are mixed in the mixing chamber to make hydrogen-rich water. During the production process, hydrogen and water need to be fully mixed to achieve the purpose of hydrogen dissolution. This device directly injects hydrogen into water for mixing, and both hydrogen and water are untreated, with larger particle sizes, resulting in insufficient mixing and being not conducive to human absorption. Summary of the Utility Model

[0004] The utility model overcomes the shortcomings in the prior art and provides a hydrogen permeation method hydrogen mixing and hydrogen dissolving pipe to achieve the effect of sufficient mixing between hydrogen and water.

[0005] In order to solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] A hydrogen permeation method hydrogen mixing and hydrogen dissolving pipe includes a hydrogen inlet pipe member and a hydrogen decomposition membrane wound around the outside of the hydrogen inlet pipe member. A gap for water to flow in and out is formed between adjacent hydrogen decomposition membranes along the length direction, and the hydrogen decomposition membrane is communicated with the gap; both ends of the hydrogen inlet pipe member are provided with air inlets, and a plurality of air outlet holes are distributed on the side surface of the hydrogen inlet pipe member. Hydrogen enters the hydrogen inlet pipe member from the air inlets, is decomposed by the hydrogen decomposition membrane through the air outlet holes, and then enters the gap to be mixed with water and discharged.

[0007] Furthermore, the hydrogen decomposition membrane includes a first nanofiltration membrane and a second nanofiltration membrane, and a spacer membrane is arranged between the first nanofiltration membrane and the second nanofiltration membrane.

[0008] Furthermore, a number of decomposition holes are distributed on both the first nanofiltration membrane and the second nanofiltration membrane, and a number of permeation holes are distributed on the spacer membrane.

[0009] Furthermore, the decomposition holes, the permeation holes and the gaps are interconnected.

[0010] Furthermore, a first intake cavity and a second intake cavity are arranged in the hydrogen inlet pipe fitting, and a spacer layer is arranged between the first intake cavity and the second intake cavity.

[0011] Furthermore, one end of the air inlet, the first intake cavity and the air outlet are interconnected, and the other end of the air inlet, the second intake cavity and the air outlet are interconnected.

[0012] Furthermore, an adhesive layer is arranged on the side of the air outlet, and the inner end of the hydrogen decomposition membrane is adhered to the adhesive layer.

[0013] Furthermore, a waterproof membrane is wound and connected to the outer end of the hydrogen decomposition membrane.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] Hydrogen and water will flow through the hydrogen decomposition membrane for decomposition and then be mixed with each other. Since the diameters of the decomposition holes and the permeation holes are small, the particle sizes of the water and hydrogen after decomposition by the hydrogen decomposition membrane are small, so that the hydrogen and water can be fully mixed. The hydrogen decomposition membrane is composed of a first nanofiltration membrane, a second nanofiltration membrane and a spacer membrane. By spacing between the first nanofiltration membrane and the second nanofiltration membrane through the spacer membrane, the smooth flow of hydrogen can be effectively ensured.

Specific embodiments

[0023] The following describes the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0024] As Figures 1 to 3 shown, a hydrogen permeation method hydrogen-mixed and hydrogen-dissolved pipe includes a hydrogen inlet pipe fitting 1 and a hydrogen decomposition membrane 2 wound around the outside of the hydrogen inlet pipe fitting 1. A gap 204 for accommodating the inflow and outflow of water is formed between adjacent hydrogen decomposition membranes 2 along the length direction. The hydrogen decomposition membrane 2 is communicated with the gap 204. Air inlet holes 101 are provided at both ends of the hydrogen inlet pipe fitting 1, and a plurality of air outlet holes 102 are distributed on the side surface of the hydrogen inlet pipe fitting 1. The working principle of this hydrogen-mixed and hydrogen-dissolved pipe is that water enters from one end of the gap 204, and after being decomposed by the hydrogen decomposition membrane 2, the water can flow into the adjacent gap 204. Hydrogen enters the hydrogen inlet pipe fitting 1 from the air inlet hole 101, and then after being decomposed by the hydrogen decomposition membrane 2 from the air outlet hole 102, it enters the gap 204 to be fully mixed with water to form hydrogen-rich water, and then is discharged from the other end of the gap 204. The decomposed water and hydrogen after passing through the hydrogen decomposition membrane 2 have smaller particle sizes, so that hydrogen and water can achieve a sufficient mixing effect.

[0025] Specifically, as Figures 1 to 4 shown, the hydrogen decomposition membrane 2 includes a first nanofiltration membrane 201 and a second nanofiltration membrane 202. A spacer membrane 203 is provided between the first nanofiltration membrane 201 and the second nanofiltration membrane 202. In the state without the spacer membrane 203, when water passes through the hydrogen decomposition membrane 2, the first nanofiltration membrane 201 and the second nanofiltration membrane 202 will be adhered together, resulting in the inability of hydrogen to flow. Therefore, by spacing between the first nanofiltration membrane 201 and the second nanofiltration membrane 202 through the spacer membrane 203, the smooth flow of hydrogen can be effectively guaranteed.

[0026] A plurality of decomposition holes 2011 are distributed on both the first nanofiltration membrane 201 and the second nanofiltration membrane 202. A plurality of permeation holes 2031 are distributed on the spacer membrane 203. The decomposition holes 2011, the permeation holes 2031 and the gap 204 are connected to each other, effectively ensuring the smooth flow of hydrogen and water. Taking hydrogen as an example, hydrogen will enter the gap 204 after being decomposed by the decomposition holes 2011 and the permeation holes 2031.

[0027] A paste layer is provided on the side of the air outlet hole 102, and the inner end of the hydrogen decomposition membrane 2 is adhered to the paste layer, so as to ensure the fixed connection between the hydrogen decomposition membrane 2 and the hydrogen inlet pipe component 1 while not affecting the flow of hydrogen through the air outlet hole 102 to the hydrogen decomposition membrane 2 for decomposition.

[0028] The outer end of the hydrogen decomposition membrane 2 is wound and connected with a waterproof membrane 3. The waterproof membrane 3 wraps the hydrogen decomposition membrane 2 on the outside, and the waterproof membrane 3 has a waterproof function to prevent water from penetrating through the hydrogen decomposition membrane 2 to the outside of the hydrogen-mixed and hydrogen-dissolved pipe.

[0029] As Figure 5 shown, a first intake cavity 103 and a second intake cavity 104 are provided in the hydrogen inlet pipe component 1. An interlayer 105 is provided between the first intake cavity 103 and the second intake cavity 104. One end intake port 101, the first intake cavity 103 and the air outlet hole 102 are connected and communicated with each other. The other end intake port 101, the second intake cavity 104 and the air outlet hole 102 are connected and communicated with each other. When the two end intake ports 101 are connected to an external hydrogen inlet device, the first intake cavity 103 and the second intake cavity 104 are in a sealed state. When hydrogen enters the first intake cavity 103 and the second intake cavity 104, air pressure will be generated. Separated by the interlayer 105, it can ensure that the air pressures generated by the two will not collide, and at the same time, hydrogen will be discharged from the corresponding air outlet hole 102.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
