Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen-rich water preparation, and in particular to a hydrogen-rich water preparation device and method. Background Art

[0002] As the name implies, hydrogen water is water containing hydrogen. Since the discovery of the medical and biological effects of hydrogen, the international medical and biological communities have been actively studying it in recent years. Hydrogen has a selective antioxidant effect. Hydrogen can actively choose to combine with free radicals that are harmful to organisms to form water. The medical community generally believes that the free radical theory is one of the root causes of disease and aging. Hydrogen selectively neutralizes harmful free radicals, providing a treatment for diseases caused by oxidative damage, and more importantly, providing a preventive measure for the human body to prevent the occurrence of diseases and aging. Hydrogen is the lightest element of all elements and exists in the form of gas at room temperature and pressure. One of the ways for the human body to use hydrogen is to dissolve hydrogen in high-purity water, use water as a carrier to enter the body, and dissipate it in the body, thereby reducing the oxidation caused by harmful free radicals in the human body. The solubility of hydrogen in water is very low and it is difficult to preserve. How to dissolve as much hydrogen as possible in water and preserve it well has become an important indicator for measuring hydrogen water.

[0003] The existing methods for preparing supersaturated hydrogen-rich water are mainly the following:

[0004] (1) In a sealed pressure container, magnesium hydride metal is used to react with water to produce hydrogen gas. After continuous production of hydrogen gas, a certain pressure is formed and it combines with water to produce high-concentration hydrogen-rich water. However, the hydrogen production effect of magnesium hydride will increase as the amount of use increases. However, with the increase in the amount of use, residual byproducts will remain in the water during the catalytic process, seriously affecting the water quality. After drinking, it will cause excessive intake of magnesium metal in the human body. If the amount used is small, the gas production is small and a certain pressure cannot be formed in the container in a short time, thus failing to achieve the effect of high-concentration hydrogen-rich water. In addition, this method has the disadvantage that the catalytic reaction effect of magnesium hydride will decay rapidly over time.

[0005] (2) After water is passed through the electrolytic cell, the water is electrolyzed to produce hydrogen. A multi-layer water channel is designed inside the electrolytic cell to increase the residence time of water in the electrolytic cell to facilitate full electrolysis, and the electrolytic plate stacking is increased. The purpose is also to increase the contact time between water and the electrolytic plate to enhance the electrolysis effect, and a valve is set at the water outlet of the electrolytic cell to reduce the water output so as to increase the internal pressure of the electrolytic cell to achieve high-concentration hydrogen-rich water. The disadvantage of the electrolytic cell water flow method is that in order to fully electrolyze the water, it is necessary to increase the residence time of the water in the electrolytic cell. Therefore, the flow rate must not be too fast, resulting in a small amount of water output. In order to increase the pressure in the cell, setting a valve at the water outlet will cause the water to be over-pressured when it is discharged, and the water will flow out in a jet-like shape. The hydrogen dissolved in the water is instantly released into the air, and it is impossible to achieve high-concentration hydrogen-rich water.

[0006] (3) Through the gas-liquid mixing pressurization method, after filling the sealed container with water, hydrogen is injected under pressure to form a certain pressure in the container so that the hydrogen and water combine to produce high-concentration hydrogen-rich water. The gas-liquid mixing method also combines water and hydrogen after the container is pressurized, but when the water is discharged, the jet effect caused by the high pressure causes the hydrogen dissolved in the water to be instantly released into the air, and high-concentration hydrogen-rich water cannot be produced.

[0007] (4) A bypass is set up in the channel where water passes through the Venturi method to supply hydrogen into the water channel. According to the Venturi effect, hydrogen will be automatically sucked from the bypass while the water flows and combined with water to produce high-concentration hydrogen-rich water. The Venturi method also forms pressure when the water is discharged, and the hydrogen mixed in the water will instantly lose to the air. In order to fully mix, the hydrogen in the bypass needs to be supplied with a large amount of air, otherwise the gas cannot keep up with the water flow rate, so the cost of the gas production device will increase accordingly.

[0008] In summary, the art currently requires a device and method for quickly and effectively preparing hydrogen-rich water. Summary of the invention

DETAILED DESCRIPTION

[0035] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0036] Example 1: A hydrogen-rich water preparation device.

[0037] like Figure 1 As shown, a hydrogen-rich water preparation device of a preferred embodiment of the present invention comprises: a water tank 1 and a plurality of pipelines, wherein the water tank 1 is provided with a water inlet end a, a water inlet end b, a water outlet end c and an air inlet end d; a first tank body 2, wherein the first tank body 2 is provided with a water inlet end e, a water outlet end f and an air inlet and outlet end g, wherein the water inlet end e of the first tank body 2 is connected to the water outlet end c of the water tank 1 through the pipeline, the water outlet end f of the first tank body 2 is connected to the water inlet end a of the water tank 1 through the pipeline, the air inlet and outlet end g of the first tank body 2 is connected to the air inlet end d of the water tank 1 through the pipeline, and the air inlet and outlet end g of the first tank body 2 is also connected to a hydrogen supply device through the pipeline; a second tank body 3, wherein the second tank body 3 is provided with a water inlet end h, a water outlet end i and The air inlet and outlet ends j, the water inlet end h of the second tank body 3 is connected to the water outlet end c of the water tank 1 through the pipe, the water outlet end i of the second tank body 3 is connected to the water inlet end b of the water tank 1 through the pipe, and the air inlet and outlet ends j of the second tank body 3 are connected to the water inlet end e of the first tank body 2 through the pipe; a water pump 4, the water pump 4 is arranged on the pipe connected to the water outlet end c of the water tank 1, and the water pump 4 is connected to the water inlet end e of the first tank body 2 and the water inlet end h of the second tank body 3 through the pipe respectively; a water outlet 13, the water outlet 13 is arranged on the pipe connecting the water outlet end f of the first tank body 2 and the water inlet end a of the water tank 1; a plurality of switch valves, each of the switch valves is arranged on each of the pipes in a one-to-one correspondence.

[0038] Based on the above scheme, the working principle of this embodiment is as follows: first, the water pump 4 is started to pass the water in the water tank 1 into the first tank body 2 and the second tank body 3 and squeeze out the gas therein. When the first tank body 2 and the second tank body 3 are full of water, hydrogen is passed into the first tank body 2 through the hydrogen supply device, and the hydrogen passed into the first tank body 2 pushes the water back into the water tank 1. When the water in the first tank body 2 reaches a certain position, the switch valve at the water outlet f is closed, and then the hydrogen in the first tank body 2 enters the second tank body 3 and pushes the water back into the water tank 1. When the water in the second tank body 3 reaches a certain height, the corresponding switch valve is also closed; when the hydrogen in the first tank body 2 forms a certain pressure, water is added to the first tank body 2 through the water tank 1, and the water and hydrogen are mixed to form hydrogen-rich water; before the hydrogen-rich water is taken out, the first tank body 2 needs to be depressurized, and the depressurization method is to pass the compressed hydrogen in the first tank body 2 into the second tank body 3, and after the depressurization, the switch valve at the water outlet 13 can be opened to take water.

[0039] Here, an alternative solution is proposed in which the water outlet 13 is arranged on the pipe connecting the water outlet end f of the first tank body 2 and the water inlet end a of the water tank 1. The water outlet 13 is connected to the water outlet end f of the first tank body 2 through a pipe alone. By setting two separate through passages to connect the water outlet end f of the first tank body 2, the two pipes do not affect each other when in use, which is more convenient to use.

[0040] Preferably, the switch valve on the connecting pipe between the water outlet end c of the water tank 1 and the water inlet end h of the second tank body 3 is set to be the first valve 5, the switch valve on the connecting pipe between the gas inlet and outlet ends j of the second tank body 3 and the water inlet end e of the first tank body 2 is set to be the second valve 6, the switch valve on the connecting pipe between the gas inlet and outlet ends g of the first tank body 2 and the gas inlet end d of the water tank 1 is set to be the third valve 7, the switch valve on the connecting pipe between the water inlet end e of the first tank body 2 and the water outlet end c of the water tank 1 is set to be the fourth valve 8, the switch valve on the connecting pipe between the hydrogen supply device and the gas inlet and outlet ends g of the first tank body 2 is set to be the fifth valve 9, the switch valve on the connecting pipe between the water outlet end f of the first tank body 2 and the water inlet end a of the water tank 1 is set to be the sixth valve 10, the switch valve on the connecting pipe between the water outlet end i of the second tank body 3 and the water inlet end b of the water tank 1 is set to be the seventh valve 11, and the switch valve on the connecting pipe between the water outlet 13 is set to be the eighth valve 12.

[0041] Preferably, a first one-way valve 14 is further provided on the pipe connecting the water inlet end e of the first tank body 2 and the water outlet end c of the water tank 1, and a second one-way valve 15 is further provided on the pipe connecting the water inlet end h of the second tank body 3 and the water outlet end c of the water tank 1. Since the atomizing nozzle arranged in the first tank body 2 will form a large pressure when spraying water, the purpose of setting the first one-way valve 14 is to ensure that water only flows in from one set direction, avoiding the situation of backflow when the pressure at the atomizing nozzle is greater than the pressure of the water pump 4. Similarly, the second one-way valve 15 is provided to avoid the backflow of water in the second tank body 3.

[0042] Preferably, the pipe connected to the water outlet end c of the water storage tank is the first pipe 16, the ends of the first pipe 16 are respectively connected to the second pipe 17 and the third pipe 18, the second pipe 17 is connected to the water inlet end h of the second tank body 3, the third pipe 18 is connected to the water inlet end e of the first tank body 2, the pipe connecting the water outlet end f of the first tank body 2 and the water inlet end a of the water tank 1 is the fourth pipe 19, the pipe connecting the water outlet end i of the second tank body 3 and the water inlet end b of the water tank 1 is the fifth pipe 20, the pipe connecting the air inlet and outlet ends j of the second tank body 3 and the water inlet end e of the first tank body 2 is the sixth pipe 21, the pipe connecting the air inlet and outlet ends g of the first tank body 2 and the air inlet end d of the water tank 1 is the seventh pipe 22, and the pipe connecting the air outlet and air inlet ends g of the first tank body 2 and the air inlet end d of the water tank 1 is the seventh pipe 22. The pipeline connecting the gas inlet and outlet ends g of the first tank body 2 and the hydrogen supply device is the eighth pipeline 23, and the pipeline connecting the water outlet end f of the first tank body 2 and the water outlet 13 is the ninth pipeline 24; the water pump 4 is arranged on the first pipeline 16, the first one-way valve 14 and the fourth valve 8 are arranged on the third pipeline 18 in sequence, the second one-way valve 15 and the first valve 5 are arranged on the second pipeline 17 in sequence, the second valve 6 is arranged on the sixth pipeline 21, the third valve 7 is arranged on the seventh pipeline 22, the fifth valve 9 is arranged on the eighth pipeline 23, the sixth valve 10 is arranged on the fourth pipeline 19, the seventh valve 11 is arranged on the fifth pipeline 20, and the eighth valve 12 is arranged on the ninth pipeline 24.

[0043] Preferably, a high-pressure control valve 25 is further provided on the fourth pipeline 19, and the high-pressure control valve 25 is electrically connected to the water pump 4. The pressure of the mixture of hydrogen and water in the first tank 2 is detected by the high-pressure control valve 25, and when the detected pressure reaches a preset detection threshold, a control signal is sent to the water pump 4, and the water pump 4 stops working after receiving the signal.

[0044] Preferably, a plurality of atomizing nozzles are arranged in the first tank body 2, and each of the atomizing nozzles is connected to the water inlet end e of the first tank body 2. The water introduced into the first tank body 2 from the water tank 1 is sprayed out through the atomizing nozzles to form fine mist water, and the fine mist water and the hydrogen in the first tank body 2 can be more quickly and better fused to form hydrogen-rich water. The number of atomizing nozzles can be set according to actual needs. For those with no excessive production efficiency requirements, a small number of atomizing nozzles can be set, and for those with high efficiency requirements, a larger number of atomizing nozzles need to be set accordingly.

[0045] Preferably, the volume of the second tank body 3 is several times the volume of the first tank body 2. In this embodiment, the preferred multiple is more than 2 times. When the multiple is larger, that is, the more gas is squeezed back into the first tank body 2 by the second tank body 3, the gas pressure of the first tank body 2 will be greater. For example, if the pressure is 2KG when the pressure is squeezed back into the first tank body 2, then 4 times is 4KG. When adding water, if the pressure is 8KG, the water level of the first tank body 2 will still be at the half position, but because the total pressure is increased, the concentration of hydrogen-rich water will also increase to 8.0ppm. In addition, when the gas of the first tank body 2 is squeezed back into the second tank body 3, since the volume of the second tank body 3 is several times that of the first tank body 2, the hydrogen pressure between the first tank body 2 and the second tank body 3 is easy to reach equilibrium, and a part of the water will remain in the second tank body 3 and will not be completely discharged by the gas when the pressure is balanced, ensuring that the internal gas does not leak out.

[0046] Preferably, a liquid level sensor is provided in each of the first tank body 2 and the second tank body 3, and the liquid level sensor is electrically connected to the water pump 4 and each of the switch valves, respectively. The water level conditions in the first tank body 2 and the second tank body 3 can be monitored in real time by the liquid level sensor, and the water level conditions include the full water level, the lowest water level and the mixed water level of the first tank body 2, and the full water level and the lowest water level of the second tank body 3. When the liquid level sensor detects the corresponding water level, the corresponding switch valve is controlled to be opened or closed.

[0047] Preferably, observation ports are provided on the first tank body 2 and the second tank body 3. The observation ports are used as an alternative to the liquid level sensor, and the water level in the first tank body 2 and the second tank body 3 can be directly observed to facilitate timely adjustment.

[0048] Preferably, the water inlet end e is arranged at the top of the first tank body 2 , the water outlet end f is arranged at the bottom of the first tank body 2 , and the water inlet end h and the water outlet end i are both arranged at the bottom of the second tank body 3 .

[0049] In summary, in this embodiment, hydrogen can be first collected in the first tank body 2 by a small amount of hydrogen supply device, and then water and hydrogen can be efficiently mixed in the reverse direction by spraying water mist, thereby reducing costs. The second tank body 3 can relieve the pressure of the supersaturated hydrogen-rich water with pressure in the first tank body 2, so that the supersaturated hydrogen-rich water in the first tank body 2 is not splashed due to the pressure during the discharge process, resulting in instantaneous loss of hydrogen in the supersaturated hydrogen-rich water, thereby ensuring that the water discharged from the first tank body 2 is supersaturated hydrogen-rich water. In addition, by setting the collection liquid level height or observation port and other means, when the water discharge from the first tank body 2 reaches the lowest water level line, the drainage will be cut off to ensure that the hydrogen in the first tank body 2 does not leak out. When the first tank body 2 releases the hydrogen to the second tank body 3, the water in the second tank body 3 will be pushed into the water tank 1 due to the hydrogen from the first tank body 2. However, when the water in the second tank body 3 approaches the lowest water level line, the drainage will be cut off to seal the hydrogen in the first tank body 2 and the second tank body 3 from leaking out. The advantage of this is that the hydrogen in the first tank body 2 and the second tank body 3 (or even multiple tanks) can be kept in the first tank body 2 and the second tank body 3 and fully utilized. There is no need to frequently start the hydrogen supply device to add gas, which can shorten the water production time each time, reduce the gas volume requirements of the hydrogen supply device, extend the life of the machine, and reduce unnecessary energy consumption and noise.

[0050] Example 2: A method for preparing hydrogen-rich water.

[0051] A method for preparing hydrogen-rich water provided in this embodiment is implemented based on the preparation device described in Example 1, and the steps include:

[0057] Preferably, step S1 is specifically as follows: in the initial stage, all switch valves are in the closed state, the first valve 5, the second valve 6 and the third valve 7 are opened, and the water pump 4 is started. The water in the water tank 1 will pass through the water pump 4, the second one-way valve 15, and the first valve 5 in sequence, and be injected from the bottom of the second tank body 3.

At this time, the water in the first tank body 2 will be continuously discharged from the bottom of the first tank body 2 through the sixth valve 10 into the water tank 1 due to the pressure generated by the entry of hydrogen. After the water in the first tank body 2 is drained, the sixth valve 10 is closed. Open the second valve 6 and the seventh valve 11, drain the water in the second tank body 3 until a certain level of water remains in the second tank body 3, close the second valve 6 and the seventh valve 11, and close the hydrogen supply device at the same time.

[0059] Preferably, the step S3 is specifically as follows: when making water, the first valve 5 and the second valve 6 are opened, the water pump 4 is turned on, the water is introduced to squeeze the hydrogen in the first tank body 2 and the second tank body 3 into the first tank body 2 to form a certain pressure, and then the first valve 5 and the second valve 6 are closed. The fourth valve 8 is opened, and the water pump 4 adds water to the first tank body 2. At this time, the water in the water tank 1 will pass through the water pump 4, the first one-way valve 14, and the fourth valve 8, and will be sprayed into the first tank body 2 in the form of fine mist from the atomizing nozzle at the top of the first tank body 2. The first tank body 2 itself has hydrogen with a certain pressure. At this time, the water mist can be fully combined with the internal hydrogen to generate supersaturated hydrogen-rich water. When the water level in the first tank body 2 reaches a certain height or a certain pressure, the pressure in the first tank body 2 is detected by the high-pressure control valve 25. When the detected pressure value reaches a preset threshold, the fourth valve 8 is closed and the water pump 4 also stops working at the same time.

[0060] Preferably, the step S4 is specifically as follows: when taking water, first open the second valve 6 and the seventh valve 11, at this time, the hydrogen compressed in the first tank body 2 will enter the second tank body 3 from the top of the first tank body 2 through the second valve 6, and the water in the second tank body 3 will be pushed out from the bottom of the second tank body 3 by the hydrogen and discharged into the water tank 1 through the seventh valve 11, and then close the seventh valve 11. The size of the second tank body 3 is to accommodate all the hydrogen discharged from the first tank body 2 until the pressure is 0, and some water will be retained at the bottom, and will not completely flow into the water tank 1 to cause hydrogen to leak into the water tank.

[0061] Preferably, the step S5 is specifically as follows: at this time, the pressure in the first tank body 2 has been completely released, and the eighth valve 12 is opened to take water. Since there is no pressure and other air inlet in the first tank body 2, it is not easy for water to flow out. At this time, the first valve 5, the second valve 6 and the water pump 4 are opened, and the water will pass through the one-way valve and the first valve 5 and enter the second tank body 3 from the bottom of the second tank body 3 and push the hydrogen in the second tank body 3 from the top through the second valve 6 into the first tank body 2. At this time, the water in the first tank body 2 is pushed out from the water outlet of the eighth valve 12 due to the hydrogen from the second tank body 3. When a certain amount of water in the first tank body 2 is discharged but not completely discharged, the eighth valve 12 is closed, the water is taken, the water pump 4 stops working, and then enters the standby state (step S4 pressure relief state).

[0062] Preferably, liquid level sensors are provided in the first tank body 2 and the second tank body 3, and the liquid level sensors are electrically connected to the water pump 4 and each of the switch valves, respectively. In the step S1, when the liquid level sensor detects that the first tank body 2 and the second tank body 3 are full of water, the water pump 4 stops working; in the step S2, when the liquid level sensor detects that the water level of the second tank body 3 reaches the set minimum water level, the second valve 6 and the seventh valve 11 are closed; in the step S3, when the liquid level sensor detects that the water level of the first tank body 2 reaches the set height, the fourth valve 8 is closed and the water pump 4 stops working; in the step S4, when the liquid level sensor detects that the water level of the second tank body 3 reaches the set height, the seventh valve 11 is closed.

[0063] Preferably, both the first tank body 2 and the second tank body 3 are provided with observation ports. In the step S1, when it is observed through the observation port that the first tank body 2 and the second tank body 3 are full of water, the water pump 4 is controlled to stop working; in the step S2, when it is observed through the observation port that the water level of the second tank body 3 reaches a set minimum water level, the second valve 6 and the seventh valve 11 are controlled to be closed; in the step S3, when it is observed through the observation port that the water level of the first tank body 2 reaches a set height, the fourth valve 8 is controlled to be closed and the water pump 4 stops working; in the step S4, when it is observed through the observation port that the water level of the second tank body 3 reaches a set height, the seventh valve 11 is closed.

[0064] Preferably, in step S2, when it is determined that a certain level of water remains in the second tank body 3, the second valve 6 and the seventh valve 11 are closed. The specific method for determining the remaining certain level of water is as follows: the amount of gas intake can be controlled, for example, 600ml of gas is input into the first tank body 2, and 1200ml of gas is input into the second tank body 3. When the first tank body 2 is full of gas, the second valve 6 and the seventh valve 11 are opened to add gas twice the volume of the first tank body 2 to stop adding gas. At this time, the water in the second tank body 3 will be driven out by the gas into the water tank 1, and the amount of water remaining in the second tank body 3 after stopping adding gas is the remaining certain level of water (because the size of the second tank body 3 is 1800ml, and if the gas intake is 1200ml, 600ml of water can be left).

[0065] Preferably, in step S4, the specific method for judging that the water level in the first tank body 2 reaches a certain height or a certain pressure is as follows: when the two gases in the second tank body 3 are all squeezed into the first tank body 2, a gas pressure of about 2KG will be formed in the first tank body 2, and pressure will be formed when the water pump in S3 injects water into the first tank body 2 and the second tank body 3. When the water is injected to a pressure of 4KG in the first tank body 2, the water level in the first tank body 2 is about halfway between the first tank body 2, and the hydrogen-rich water is about 4.0ppm at this time. When water continues to be added and pressurized, for example, the total pressure is 6KG, the water level will rise more than 4KG, to about 70% of the height of the first tank body 2, and the concentration of hydrogen-rich water will be 6.0ppm. However, water cannot be added, because the water level will rise, and the gas space will be reduced. When the spray is sprinkled, the mixing effect with the gas will be weakened. If you want to continue to increase the concentration, you can set the gas pressure in the first tank 2 to 3KG and the water inlet pressure to 6KG. In this way, the water level is also at half the position and the concentration is also 6.0ppm. When the water inlet pressure reaches 8KG, the water level will rise to 70% height and the concentration will reach 8.0ppm, and so on. When the gas pressure in the first tank 2 increases, the volume of the second tank 3 should also be increased to have enough space for pressure relief. Preferably, in step S4, the method for judging whether to close the seventh valve 11 is as follows: if 1 portion of gas (600 ml) is injected into the first tank body 2, 2 portions of gas (1200 ml) are injected into the second tank body 3, and the total volume of the second tank body 3 is 1800 ml, then after opening the second valve 6 and the seventh valve 11, the 2 kg gas compressed in the first tank body 2 (the origin of the aforementioned 2 kg) will definitely discharge about 1200 ml + 300 ml = 1500 ml of water in the second tank body 3. , (300ml is because if the first tank body 2 is designed to have a volume of 600ml, when there is 2KG hydrogen pressure in the first tank body 2, and the first tank body 2 forms a 4KG pressure after adding water, the water level in the first tank body 2 will be about 300ml at the halfway position, and this 300ml of water will occupy the position of the gas, so the displacement of the second tank body 3 during pressure relief should be added with this 300ml), so that there is still 300ml of water remaining in the second tank body 3 (1800-1500=300). This process is instantaneous and can be controlled by time, for example, opening the seventh valve 11 for thirty seconds and then closing it.

[0066] Preferably, when it is necessary to continuously generate saturated hydrogen-rich water, in the pressure relief state of step S4, the fourth valve 8 and the eighth valve 12 are opened, the water pump 4 is turned on until the water extraction is completed, and then the fourth valve 8 and the eighth valve 12 are closed. Through the adjustment of this step, saturated hydrogen-rich water can be continuously produced. In both of these specific methods, only a small amount of hydrogen is consumed. When the hydrogen is insufficient, the water level of the first tank body 2 will slowly rise to a certain level, and then step S3 can be started to add gas.

[0067] In summary, the method for preparing hydrogen-rich water provided in this embodiment can instantly produce supersaturated hydrogen-rich water, and is also equipped with a pressure relief function, which can solve the problem that the products on the market cannot obtain supersaturated hydrogen-rich water because the hydrogen-rich water is prepared by pressurizing the container but is accompanied by pressure relief when taking water. Because the method fully utilizes hydrogen without waste, supersaturated hydrogen-rich water can be obtained with very little hydrogen used each time, so the requirements for the hydrogen supply device are low, which can save costs.

[0068] 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 substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
