Description

[Technical Field]

[0001] The present invention relates to the technical field of hydrogen and oxygen production, and more particularly to an apparatus and method for generating a hydrogen and oxygen mixed gas with adjustable hydrogen content. [Background technology]

[0002] Oxygen plays an important role in human metabolism. Oxygen deficiency can lead to illnesses such as upper respiratory tract infections, insomnia, and pulmonary and cerebral edema. In recent years, the use of hydrogen has expanded in the fields of medicine, health, and wellness, with hydrogen gas and hydrogen-containing liquid products gaining attention. Hydrogen's biological effects, such as antioxidant, anti-inflammatory, anti-apoptotic, and cell repair, can be utilized to improve physical condition and prevent disease. Numerous studies have shown that hydrogen selectively removes harmful free radicals from the body and has other health benefits, including immune regulation and metabolic regulation. Hydrogen also has complementary therapeutic effects for cerebral ischemia, Alzheimer's disease, lung injury, kidney injury, tumor treatment, and sleep improvement. Hydrogen also has cosmetic anti-aging properties, anti-UV damage, and skin tissue repair.

[0003] Currently, most commercially available hydrogen generators and hydrogen-oxygen generators used in medical institutions have complex configurations and can only generate high-purity hydrogen or a hydrogen-oxygen mixed gas with a fixed hydrogen / oxygen ratio (hydrogen / oxygen = 66.6%:33.3%); no hydrogen / oxygen mixed gas generator with adjustable hydrogen content has yet been reported.

[0004] Therefore, in order to overcome the shortcomings of the prior art, it is necessary to provide a hydrogen and oxygen mixed gas generator suitable for medical care and allowing users to adjust the hydrogen content. Summary of the Invention [Problem to be solved by the invention]

[0005] The present invention has been made in consideration of the technical problems, such as the complicated configuration of the hydrogen and hydrogen-oxygen mixed gas generation equipment in the above-mentioned prior art and the inability to adjust the hydrogen to oxygen ratio, and provides an apparatus and method for generating hydrogen and oxygen mixed gas with adjustable hydrogen content. The present invention mainly combines the air separation oxygen generation process with the technology of hydrogen production by water electrolysis, and by rationally designing and optimizing the structure of the above-mentioned apparatus, it is possible to adjust and control the gas flow rate and hydrogen content to achieve multi-mode supply, and has the advantages of being compact, having a long life, and being able to adjust the gas output and hydrogen content of the hydrogen and oxygen mixed gas. [Means for solving the problem]

[0006] The technical means of the present invention are as follows:

[0007] One aspect of the present invention is an apparatus for generating a hydrogen and oxygen mixed gas with adjustable hydrogen content, the apparatus comprising: a case for housing an oxygen generator, a hydrogen generator, a control module, and a power supply module; the power supply module supplies power to the oxygen generator, the hydrogen generator, and the control module; The oxygen generator separates and stores oxygen from the air, The hydrogen generator generates hydrogen or a mixed gas of hydrogen and oxygen by electrolyzing water, The control module controls and adjusts the flow rate of oxygen, detects the concentration of oxygen, and adjusts the flow rate and hydrogen content of the hydrogen-oxygen mixed gas within a predetermined range; The oxygen generated by the oxygen generator and the hydrogen or hydrogen and oxygen mixed gas generated by the hydrogen generator flow through a pipeline into the outlet of the hydrogen and oxygen mixed gas generator, where they are humidified and discharged or directly discharged.

[0008] Furthermore, the oxygen generating device includes an air compressor, a condenser connected to the air compressor, an adsorption device connected to the condenser for separating oxygen from the air, a gas tank connected to the adsorption device for storing oxygen, and a silencer connected to an exhaust pipe for other gases in the air.

[0009] The oxygen generator's operating principle is based on pressure swing adsorption, using zeolite molecular sieves as adsorbents. Due to the selective adsorption properties of zeolite molecular sieves, nitrogen is adsorbed in large quantities by the zeolite molecular sieves, while oxygen is concentrated in the gas phase, achieving the separation of nitrogen and oxygen through pressure swing adsorption. Two adsorption towers are used, one for adsorption to generate oxygen, and the other for desorption and regeneration. A control module controls the opening and closing of the combined air valve, allowing the two adsorption towers to operate in a cyclical alternating sequence, thereby continuously generating high-quality oxygen.

[0010] The adsorption device is an adsorption tower group including at least two adsorption towers, and a composite air valve is provided between the condenser and the adsorption tower group to control the air passage and operate in a cyclical alternating manner by pressure swing adsorption to separate oxygen from the air. A radiator is provided on one side of the condenser to dissipate heat from the condenser.

[0011] Furthermore, the hydrogen generating device includes an electrolytic cell and a catalytic electrode, the electrolytic cell is provided with an outlet for hydrogen or a mixed gas of hydrogen and oxygen, the outlet for hydrogen or a mixed gas of hydrogen and oxygen is provided with a gas-liquid separator, and the generated hydrogen or mixed gas of hydrogen and oxygen is filtered and dried in multiple stages before flowing into an exhaust pipe communicating with an oxygen exhaust pipe.

[0012] Preferably, the dried hydrogen and oxygen mixed gas passes through a flame arrester before flowing into the junction line, which can effectively ensure the safety of the device.

[0013] Furthermore, the specified ranges for the flow rate and hydrogen content of the hydrogen-oxygen mixed gas are 0.03 to 7 L / min for the gas output of the hydrogen-oxygen mixed gas and 0% to 100% for the hydrogen-oxygen mixed gas. When the oxygen generator is shut down, the hydrogen outlet of the hydrogen generator can be turned on to supply hydrogen at nearly 100% concentration. When the oxygen generator is shut down, the hydrogen-oxygen mixed gas outlet of the hydrogen generator can be turned on to supply a hydrogen-oxygen mixed gas with a hydrogen-oxygen ratio of 66.6%:33.3%. Alternatively, the oxygen generator can be operated alone to supply 100% oxygen. Alternatively, both can be operated simultaneously to adjust the hydrogen content within the required range. Furthermore, if the hydrogen content exceeds the explosion limit, a flame arrester can be installed between the confluence and the outlet to further ensure the safety of the device.

[0014] Furthermore, the case includes a main case and a top lid and a bottom lid provided at both the top and bottom ends of the main case, the top lid is provided with a water inlet for injecting water into the hydrogen generation device, the water inlet is provided with a sealing cap, and a humidifier bottle is provided inside the top lid.

[0015] Additionally, the top cover is further provided with a control panel display and a flow meter display window.

[0016] Furthermore, the bottom cover is provided with a plurality of rows of air intake holes, and the bottom cover is provided with casters for easy movement.

[0017] Furthermore, a lighting panel is provided at the bottom of the humidifying bottle, and a viewing window for the humidifying bottle is provided on the top cover of the side of the humidifying bottle.

[0018] Another aspect of the present invention is a method for using the above-mentioned hydrogen-oxygen mixed gas generator with adjustable hydrogen content, in which water is injected into the hydrogen generator, the hydrogen-oxygen mixed gas generator is turned on, and the oxygen generator and hydrogen generator are operated. Air enters the main case through the intake hole in the bottom cover of the case, enters the air compressor, passes through the condenser, and then enters the combined air valve, and enters a selected group of adsorption towers to perform pressure swing adsorption, separating oxygen from other gases in the air. The oxygen then flows into a gas tank for flow control and concentration detection. After that, the oxygen is combined with hydrogen or hydrogen-oxygen mixed gas generated by electrolyzing water in the hydrogen generator and flows into the exhaust pipe, where it is humidified in a humidifying bottle and discharged or discharged directly, and the other gases in the air are discharged through a silencer. [Effects of the Invention]

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1. The oxygen generator of the present invention is based on the principle of pressure swing adsorption, which separates oxygen from other gases in the air to obtain high-purity oxygen for backup use.

[0021] 2. The hydrogen generating device of the present invention generates hydrogen or a mixed gas of hydrogen and oxygen based on the principle of electrolysis of water, and after multiple stages of filtration and drying, purified hydrogen or a mixed gas of hydrogen and oxygen is obtained and used as a backup.

[0022] 3. The hydrogen-oxygen mixed gas generator with adjustable hydrogen content of the present invention can adjust the flow rate and hydrogen content of the generated hydrogen-oxygen mixed gas within a preset range according to the user's needs, enabling safe, rapid, and multi-mode supply.

[0023] As described above, the hydrogen-oxygen mixed gas generator with adjustable hydrogen content of the present invention is compact, allows the gas output and hydrogen content of the hydrogen-oxygen mixed gas to be adjusted, and has a long life.

[0024] For the above reasons, the present invention can be widely used in the field of hydrogen and oxygen production. [Brief explanation of the drawings]

[0034] As shown in FIG. 1, the present invention provides a hydrogen and oxygen mixed gas generator with adjustable hydrogen content, which includes a case for housing an oxygen generator, a hydrogen generator, a control module 14, and a power supply module 19 for supplying power to the above-mentioned devices. The case includes a main case 1 and a top lid 2 and a bottom lid 3 provided at the upper and lower ends of the main case 1.

[0037] The oxygen generator separates oxygen from air and stores it for storage. The oxygen generator includes an air compressor 6, a condenser 7 connected to the air compressor 6, an adsorption device connected to the condenser 7 and separating oxygen from air, a gas tank 10 connected to the adsorption device and storing oxygen, and a silencer 28 connected to the discharge pipe for other gases. The adsorption device is an adsorption tower group 9 including two adsorption towers, and a composite air valve 8 is installed between the condenser 7 and the adsorption tower group 9. The composite air valve 8 controls the air passage, and the two adsorption towers operate in a cyclical alternating manner using a pressure swing adsorption method to separate oxygen from air. A radiator 30 is installed on one side of the condenser 7 to dissipate heat from the condenser 7. The radiator 30 is capable of air-cooling heat dissipation.

[0038] The hydrogen generation device generates hydrogen or a mixed gas of hydrogen and oxygen by electrolyzing water, and includes an electrolytic cell 20 and a catalytic electrode (electrolysis stack 21). The electrolytic cell 20 is provided with an outlet for hydrogen or a mixed gas of hydrogen and oxygen, and a gas-liquid separator 22 is provided at the outlet for hydrogen or a mixed gas of hydrogen and oxygen. The generated hydrogen or mixed gas of hydrogen and oxygen is filtered and dried in multiple stages and flows through a flame arrester 2 into a T-shaped pipe 16 that communicates with an oxygen outlet pipe.

[0039] The control module 14 controls and adjusts the oxygen flow rate, detects the oxygen concentration, and adjusts the flow rate and hydrogen content of the hydrogen-oxygen mixed gas within a predetermined range: a gas output of 0.03 to 7 L / min and a hydrogen content of 0% to 100%. The oxygen generated by the oxygen generator flows through a check valve 15, together with the hydrogen or hydrogen-oxygen mixed gas generated by the hydrogen generator, via a T-shaped pipe 16 into the outlet 17 of the hydrogen-oxygen mixed gas generator.

[0042] The oxygen generator workflow is as follows: air enters the main case 1 through the intake 24 on the bottom cover 3, passes through the first filter 5 into the air compressor 6, where it is compressed, passes through the condenser 7 into the combined air valve 8, and is then cooled by the radiator 30. The compressed air passes through the combined air valve 8 and enters the adsorption tower group 9, where oxygen is separated from other gases by pressure swing adsorption. The oxygen (oxygen air passage) enters the gas tank 10 and passes through the second filter 11. The control module 14 controls the flow rate with the flow control valve 29, displays the flow rate with the flow meter 12, and detects the concentration. After that, the air passes through the check valve 15 into the T-pipe 16, where it is combined with the hydrogen or hydrogen-oxygen mixture gas generated by electrolysis of water in the hydrogen generator. The other gases are discharged via the silencer 28.

[0043] The workflow of the hydrogen generator: Water is electrolyzed in the electrolytic cell to generate hydrogen or a mixture of hydrogen and oxygen, which then passes through the gas-liquid separator 22 and enters the flame arrestor 23, and then merges with the oxygen (oxygen channel) through the T-pipe 16. At this time, the flow rate and hydrogen content of the mixture of hydrogen and oxygen can be adjusted to a predetermined range according to the user's needs, and the mixture can be selectively passed through the outlet 17 into the humidifying bottle 18, humidified, and then discharged or directly discharged for safe and reliable use.

[0044] Depending on the user's needs, the hydrogen generator or oxygen generator can be turned on alone, or both can be turned on simultaneously, allowing for multi-mode gas supply.
