Description

TECHNICAL FIELD

[0001] The application relates to a hydrogen bubble water preparation device and specifically relates to a device and method for electrolyzing water to generate nanometer hydrogen bubble water. BACKGROUND

[0002] Due to the significant biological activity of hydrogen molecules, such as the antioxidant and anti-inflammatory effects in the fields of health care, agricultural preservation and the like, the preparation technology of hydrogen-rich water, which is an efficient delivery carrier of the hydrogen molecules, has become a research hotspot. Among them, hydrogen water rich in nanometer hydrogen bubbles has a smaller bubble particle size, a larger specific surface area and a longer residence time in liquid, and exhibits more excellent stability and biological availability than ordinary hydrogen-rich water, and has a broader application prospect.

[0003] The electrolysis water method can generate hydrogen in situ, and is one of common technical approaches for preparing hydrogen-rich water. In the technology, in order to overcome the low solubility of hydrogen in water, a Venturi tube is generally used to suck and break the hydrogen bubbles generated by electrolysis by using the negative pressure generated at the throat of the Venturi tube to realize preliminary mixing of gas and liquid. However, the existing mixing technology based on the Venturi tube has inherent limitations, which restricts the further improvement of the concentration and stability of nanometer hydrogen bubble water.

[0004] In the prior art, the Venturi tube usually works under a stable and constant water inlet pressure and flow rate. Although this steady state condition is reliable, the breaking effect of the Venturi tube on the bubbles will quickly reach a balance point. Specifically, the constant water flow makes the shear force and turbulent flow pattern generated at the throat of the Venturi tube relatively fixed, and the breaking effect on the bubbles tends to be homogenized, and it is difficult to produce a stronger and breakthrough breaking effect. This leads to the fact that the micron-sized bubble particle size distribution generated after preliminary mixing is relatively concentrated, and it is difficult to further refine, which brings a great burden to the subsequent nanometer treatment and limits the improvement of the hydrogen concentration in the final product. In addition, the breaking efficiency under this steady flow condition has an upper limit. When the water flow rate is constant, the shear force on the bubbles is also basically constant, and it is impossible to actively create more intense instantaneous pressure changes and turbulent flow patterns, so it is impossible to continuously and efficiently break the bubbles to a smaller size. The subsequent process usually needs to rely on high-energy mechanical shearing equipment for intensive treatment, which increases the complexity and energy consumption of the system. Therefore, the technical personnel in the field have long been committed to optimizing the working condition of the Venturi tube, but the ideas are mostly focused on optimizing the geometric parameters of the fixed structure or simply improving the water inlet pressure. These static optimization methods cannot fundamentally change the problem that the working efficiency of the Venturi tube is limited under the steady flow condition. Therefore, the application provides a device and method for electrolyzing water to generate nanometer hydrogen bubble water to solve the above-mentioned problems. SUMMARY

[0005] The present application aims to provide a device and method for electrolytic water generating nanometer hydrogen bubble water, which can actively and dynamically change the water inlet conditions of the Venturi tube to break the steady flow and stimulate its higher breaking potential, thereby solving the problem that the existing electrolytic water generating nanometer hydrogen bubble water device based on the Venturi tube has a relatively fixed shear force and turbulent flow form generated by the throat of the Venturi tube, and the breaking effect on the bubbles tends to be homogeneous, which makes it difficult to produce a stronger and breakthrough breaking effect, resulting in a relatively concentrated micron bubble particle size distribution after preliminary mixing, which is difficult to further refine, thereby bringing a great burden to the subsequent nanometer treatment and limiting the improvement of the hydrogen concentration in the final product.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all embodiments of the present application.

[0028] Please refer to Figures 1-10As an embodiment of the present invention, an apparatus for generating nano-hydrogen bubble water by electrolysis of water includes a frame 1. From left to right, an inlet regulating pipe 2, a venturi tube 3, a guide pipe 4, and a Tesla valve 5 are fixed on the frame 1. The inlet regulating pipe 2, the venturi tube 3, the guide pipe 4, and the Tesla valve 5 are internally connected to form a continuous flow path. One end of the inlet regulating pipe 2 is provided with multiple regulating plates 8 extending to the inlet of the venturi tube 3 and forming a variable outlet. The multiple regulating plates 8 are driven by a first driving mechanism to synchronously expand and contract radially to change the cross-sectional area of ​​the variable outlet. The first rotating shaft 19 is rotatably mounted inside the guide tube 4, and a shearing rotor 20 is fixed on the first rotating shaft 19. The second rotating shaft 21 is rotatably mounted inside the venturi tube 3, and a stirring blade 22 is fixed on the second rotating shaft 21. The second rotating shaft 21 and the first rotating shaft 19 are driven to rotate by the same first driving source.

[0029] In this embodiment, during use, hydrogen is produced by electrolyzing water, and the produced hydrogen is continuously delivered to the inlet regulating pipe 2. Simultaneously, water is pumped into the inlet regulating pipe 2 via an external water pump. The positions of multiple regulating plates 8 are adjusted by a first driving mechanism, changing the cross-sectional area of ​​the variable outlet formed by the multiple regulating plates 8. This continuously changes the flow velocity of the water entering the Venturi tube 3 from the inlet regulating pipe 2, making the flow velocity of the water entering the Venturi tube 3 dynamically changing rather than at a fixed rate. This facilitates the formation of disordered turbulence within the Venturi tube 3, thereby optimizing the Venturi effect within the Venturi tube 3. The water flow and hydrogen combine within the Venturi tube 3 to form a hydrogen-water mixture. The Venturi tube 3 breaks up large hydrogen bubbles by narrowing the tube section, initially generating micro-nano hydrogen bubbles, thus performing preliminary mixing and breaking of the hydrogen. The first driving source drives the stirring blade 22 and the shearing rotor 20 to rotate at high speed. Under the action of the stirring blade 22, the hydrogen-water mixture is mechanically stirred, mixed and broken inside the Venturi tube 3. The hydrogen-water mixture initially treated by the Venturi tube 3 enters the guide tube 4. Under the high-speed shearing action of the shearing rotor 20, the bubbles are further nano-sized. The nano-sized hydrogen-water mixture flows into the Tesla valve 5 to achieve homogenization and stabilization of the bubbles, ultimately generating high-concentration, high-stability nano-hydrogen bubble water.

[0030] As a further embodiment of the present invention, an inlet pipe 6 for conveying water into the inlet pipe 2 is fixed on the inlet regulating pipe 2, and an inlet pipe 7 for conveying hydrogen into the venturi tube 3 is fixed on the venturi tube 3.

[0031] In this embodiment, the water inlet pipe 6 is connected to an external water pump to provide water to the inside of the water inlet regulating pipe 2. The water pump also provides power for the water entering the inside of the water inlet regulating pipe 2. The water pump delivers water to the inside of the water inlet regulating pipe 2. The air inlet pipe 7 is connected to an external water electrolysis device to introduce the generated hydrogen into the inside of the venturi tube 3 and mix it with the water entering the inside of the venturi tube 3.

[0032] As a further embodiment of the present invention, the first driving mechanism includes a rotating cylinder 9 rotatably installed inside the water inlet regulating pipe 2. The rotating cylinder 9 is driven to rotate by a second driving source. An external threaded cone cylinder 14 is fixed to the end of the rotating cylinder 9. Multiple adjusting plates 8 are circumferentially distributed at equal angles on the outer periphery of the external threaded cone cylinder 14. An arc-shaped threaded sleeve 13 is fixed to one end of the adjusting plate 8. The arc-shaped threaded sleeve 13 is threadedly engaged with the external threaded cone cylinder 14. The arc-shaped threaded sleeve 13 is slidably engaged with the inner wall of the water inlet regulating pipe 2 through a sliding component, so that when the external threaded cone cylinder 14 rotates, the arc-shaped threaded sleeve 13 and the adjusting plates 8 fixed thereto are driven to move linearly along the radial direction of the water inlet regulating pipe 2 through the threaded pair.

[0033] In this embodiment, the second drive source drives the rotating drum 9 to rotate. The rotation of the rotating drum 9 causes the external threaded cone 14 to rotate synchronously. The arc-shaped threaded sleeve 13 engages with the external threaded cone 14 through a threaded fit, and the arc-shaped threaded sleeve 13 slides against the inner wall of the inlet regulating pipe 2 via a sliding assembly, causing multiple arc-shaped threaded sleeves 13 to move radially in a linear fashion. By controlling the rotation direction of the rotating drum 9 (forward and reverse rotation, and the number of rotations), the synchronous radial displacement of all regulating plates 8 can be precisely controlled. As the multiple regulating plates 8 radially contract, the cross-sectional area of ​​the resulting outlet decreases, and multiple... The radial expansion of the regulating plate 8 increases the cross-sectional area of ​​the outlet, enabling continuous and precise adjustment of the outlet cross-sectional area. By adjusting the outlet cross-sectional area, the flow velocity and pressure of the water entering the Venturi tube 3 can be actively and periodically changed, so that the flow velocity and pressure of the water entering the Venturi tube 3 are no longer fixed. This artificially creates an unsteady flow of the fluid in the Venturi tube 3, causing the hydrogen-water mixture to generate more intense and variable turbulence and instantaneous pressure changes inside the Venturi tube 3. This facilitates the generation of dynamic impacts and shear forces on the hydrogen bubbles that far exceed steady-state conditions.

[0034] As a further embodiment of the present invention, the second driving source includes a driven gear ring 10 fixed on the outer periphery of one end of the rotating drum 9 and a driving gear 11 rotatably mounted on the water inlet regulating pipe 2. The driving gear 11 meshes with the first driving motor 12. The first driving motor 12 is fixed on the water inlet regulating pipe 2. The driving gear 11 is connected to the output shaft of the first driving motor 12 and is driven to rotate by the first driving motor 12.

[0035] In this embodiment, the first drive motor 12 is electrically connected to an external power source via a wire. When the first drive motor 12 is started, it drives the drive gear 11 to rotate. Through the gear pair formed by the drive gear 11 and the driven gear ring 10, the power is transmitted to the rotating drum 9, which is driven to rotate. The first drive motor 12 drives the drive gear 11 to rotate in both directions, thus driving the rotating drum 9 to rotate in both directions.

[0036] As a further embodiment of the present invention, the sliding assembly includes a sliding key 15 fixed to the outer wall of each arc-shaped threaded sleeve 13 and a keyway 16 correspondingly opened on the inner wall of the water inlet regulating pipe 2. The sliding key 15 is slidably embedded in the keyway 16 to restrict the circumferential rotation of the arc-shaped threaded sleeve 13.

[0037] In this embodiment, the inner surface dimensions of the keyway 16 are adapted to the outer surface dimensions of the slide key 15. The sliding fit between the slide key 15 and the keyway 16 provides reliable guidance and anti-rotation function for the movement of the arc-shaped threaded sleeve 13, enabling the adjusting piece 8 to stably achieve radial linear movement.

[0038] As a further embodiment of the present invention, a static crushing grid 17 is fixedly installed inside the water inlet regulating pipe 2.

[0039] In this embodiment, the static crushing grid 17 is located inside the Venturi tube 3. When the hydrogen-water mixture flows through the grid, larger bubbles are physically cut and squeezed, resulting in additional static crushing. This complements the Venturi effect and mechanical stirring formed inside the Venturi tube 3, enhancing the primary crushing effect.

[0040] As a further embodiment of the present invention, a plurality of shearing rotors 20 are distributed at equal intervals along the axial direction of the first rotating shaft 19, and a plurality of stirring blades 22 are distributed at equal intervals along the axial direction of the second rotating shaft 21.

[0041] In this embodiment, the multi-stage distributed stirring blades 22 and shear rotor 20 ensure that the fluid is uniformly and fully processed as it flows through the entire length of the chamber. The fluid is fully stirred by the rotating stirring blades 22 when it is in the Venturi tube 3, and is fully sheared by the rotating shear rotor 20 when it passes through the guide tube 4, thus avoiding processing dead zones and improving the consistency of processing efficiency.

[0042] As a further embodiment of the present invention, the first driving source includes a dual-axis motor 18 fixed inside the guide tube 4, and the first rotating shaft 19 and the second rotating shaft 21 are both installed at the output end of the dual-axis motor 18 and driven to rotate by the dual-axis motor 18.

[0043] In this embodiment, the dual-shaft motor 18 is electrically connected to an external power source via wires. The dual-shaft motor 18 is the core power source and is connected to the first rotating shaft 19 and the second rotating shaft 21 via couplings, driving the second rotating shaft 21 and the first rotating shaft 19 to rotate simultaneously. This achieves centralized power supply and coordinated speed of the two-stage crushing, simplifies the structure, and reduces energy consumption.

[0044] As a further embodiment of the present invention, the Tesla valve 5 is provided with a Tesla valve flow channel 23 based on the Tesla valve principle for further shearing of bubbles. The end of the Tesla valve flow channel 23 is connected to a water outlet pipe 24, which is connected to an external hydrogen collection device. The external hydrogen collection device is used to collect and store the nano-hydrogen bubble water generated by the Tesla valve 5.

[0045] In this embodiment, a Tesla valve flow channel 23 based on the Tesla valve principle is provided inside the Tesla valve 5. One end of the guide pipe 4 is connected to the Tesla valve 5. The sheared and nano-processed hydrogen and water mixture enters the Tesla valve flow channel 23 inside the Tesla valve 5. The Tesla valve flow channel 23 uses its unique geometry to cause the fluid to generate opposing collisions and secondary flow inside, which performs final fine shearing and homogenization treatment on the nanobubbles and can suppress the subsequent aggregation of bubbles, greatly improving the long-term stability of nano-hydrogen bubble water.

[0046] The working principle of this invention is as follows: an external water pump pumps water into the inlet regulating pipe 2 through the inlet pipe 6, while hydrogen gas generated by water electrolysis is introduced into the venturi tube 3 through the gas inlet pipe 7. The first drive motor 12 operates, driving the rotating drum 9 to rotate through the gear pair, which in turn drives the external threaded cone 14 to rotate. Guided by the threaded pair and sliding assembly, all regulating plates 8 move radially synchronously, changing the size of the outlet of the inlet regulating pipe 2, thereby forming a fluctuating water flow that enters the venturi tube 3. This fluctuating water flow greatly optimizes the crushing efficiency of the venturi tube 3. After the hydrogen gas is drawn in and initially mixed with water, it is crushed. The mixture flows through the static crushing grid 17 inside the Venturi tube 3 for auxiliary crushing. Then, the mixture enters the rear section of the Venturi tube 3, where the dual-shaft motor 18 drives the stirring blades 22 to rotate at high speed for mechanical stirring, so that the hydrogen and water are mixed evenly and crushed. Next, the mixture enters the guide pipe 4 and is finely nano-sheared by the high-speed rotating shear rotor 20. Finally, the nano-bubble liquid flows into the Tesla valve channel 23 inside the Tesla valve 5. After being homogenized by collision in the Tesla valve channel 23, it forms a high-concentration, highly stable nano-hydrogen bubble water, which is discharged from the outlet pipe 24 to the collection device for collection.

[0047] The above embodiments are exemplary and not restrictive. Therefore, any technical solutions that can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention are included within the scope of the present invention.

S5: The nano-sized hydrogen-water mixture flows into the Tesla valve (5), where it collides and shears through the internal Tesla valve channel (23) to achieve homogenization and stabilization of the bubbles, ultimately generating high-concentration, high-stability nano-hydrogen bubble water, which is then transported to the hydrogen collection device for storage through the outlet pipe (24).
