Abstract
Description
Technical Field
[0001] The present invention relates to the field of energy utilization technology, and specifically to a green hydrogen production and heat and power cogeneration device based on solar energy conversion. Background Art
[0002] Solar energy production of green hydrogen is a technology that uses solar energy to decompose water into hydrogen and oxygen. It has the advantages of being clean, renewable, and having zero carbon emissions. It is an important development direction in the future energy field.
[0003] The principle of producing green hydrogen from solar energy is that solar panels absorb sunlight, convert light energy into electrical energy, and use electrolyzers to electrolyze water, where water molecules are decomposed into hydrogen and oxygen. Electrolyzers are usually composed of an anode, a cathode, and an electrolyte. Under the action of an electric field, water molecules lose electrons at the anode to undergo an oxidation reaction to generate oxygen, and gain electrons at the cathode to undergo a reduction reaction to generate hydrogen.
[0004] Hydrogen cogeneration means that after the generated hydrogen and oxygen enter the fuel cell, an electrochemical reaction will occur inside the fuel cell, directly converting chemical energy into electrical energy, while generating heat energy and water, and the generated electrical energy and heat energy are utilized. The comprehensive energy utilization rate can generally reach more than 90%.
[0005] After the chemical reaction of hydrogen and oxygen produces high-temperature water, the staff will store the high-temperature water in a centralized manner and then discharge it into the environment separately. The discharge of high-temperature water produced by chemical reactions will not only affect the surrounding environment, but also reduce the utilization rate of high-temperature water thermal energy, resulting in a waste of resources. The discharge of high-temperature water may cause the equipment to be subjected to greater thermal stress, resulting in a decline in the performance of equipment materials, and even problems such as cracks and deformation.

[0018] 2. The motor controls the first roller and the second roller to rotate, which indirectly drives the leak-proof disc to slide on the uneven surface of the hydrogen pipe. During the sliding process, the rubber block always fits the surface of the hydrogen pipe, and the gas sensor detects the surface of the hydrogen pipe in real time. When a leak occurs, the motor controls the leak-proof disc to stop moving, and the rubber block covers the leaking area, controls the solar panel to stop supplying power, and starts to collect the remaining hydrogen inside the hydrogen pipe. When the air pressure inside the rubber block and the ventilation groove gradually increases, the hydrogen generates a greater thrust on the slide, driving the slide to slide along the slide groove, generating an extrusion force on the rubber block. At this time, the pressing force of the rubber block on the surface of the hydrogen pipe increases, which effectively prevents the internal pressure of the rubber block from being too high, causing the rubber block to turn outward, thereby causing the hydrogen to leak again, thereby achieving a high protective effect.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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.
[0022] See also Figure 1-12The present invention provides a technical solution: a green hydrogen production and cogeneration equipment based on solar energy conversion, including a cabinet 2, a solar panel 1 is provided on one side of the cabinet 2, an electrolysis tank 4 for electrolyzing circulating water is fixedly connected inside the cabinet 2, an electrolysis tank 4 is provided inside, the solar panel 1 is used to convert light energy into electrical energy to power the electrolysis tank, a water tank 6 for storing domestic hot water is provided on one side of the electrolysis tank 4, a heat exchanger 7 is fixedly connected on the upper side of the water tank 6, a reaction mechanism 5 for producing electrical energy and thermal energy is provided on the upper side of the heat exchanger 7, and an ion resin exchanger 3 for removing impurities and ions from the chemical reaction water produced by the reaction mechanism 5 is provided on one side of the reaction mechanism 5.
[0023] Specifically, the solar panel 1 absorbs solar energy and converts it into electrical energy. The solar panel 1 is usually composed of a plurality of solar cells. When these cells are irradiated by sunlight, they will generate current due to the photoelectric effect. The electrical energy generated by the solar panel 1 will directly provide the required energy for the electrolysis tank 4 to drive the electrolysis reaction. The electrolysis tank 4 is usually provided with an anode and a cathode. The anode and the cathode are separated by an electrolyte such as a proton exchange membrane. When the current generated by the solar panel 1 connects the anode and the cathode of the electrolysis tank 4, the circulating water undergoes an electrolysis reaction in the electrolysis tank 4. At the anode, the water molecules undergo an oxidation reaction to generate oxygen, hydrogen ions and electrons. At the cathode, the hydrogen ions undergo a reduction reaction with the electrons to generate hydrogen.
[0024] See also Figure 3 An oxygen output terminal and a hydrogen output terminal are respectively provided on the upper side of the electrolytic tank 4, and an oxygen pipe 41 and a hydrogen pipe 42 are respectively fixedly connected to the oxygen output terminal and the hydrogen output terminal. An anti-leakage mechanism 8 for preventing hydrogen leakage is provided on the outer side of the hydrogen pipe 42.
[0025] Specifically, hydrogen and oxygen generated by electrolysis in the electrolytic tank 4 are discharged from the electrolytic tank through the hydrogen pipe 42 and the oxygen pipe 41 respectively. The anti-leakage mechanism 8 is used to slide on the surface of the pipeline, monitor whether the pipeline is leaking in real time, and stop moving when the pipeline leaks, and use the leaked hydrogen flow to block the leak.
[0026] See also Figure 3-Figure 7The reaction mechanism 5 includes a heat sink 52 fixedly connected to the inside of the cabinet 2, a fuel cell 56 is fixedly connected to the inside of the heat sink 52, an oxygen input end, a hydrogen input end, a power generation end and a water outlet are respectively provided on the outside of the fuel cell 56, the other end of the oxygen pipe 41 is fixedly connected to the oxygen input end of the fuel cell 56, the other end of the hydrogen pipe 42 is provided with a charging socket 43 and is fixedly connected to the hydrogen end of the fuel cell 56, the water outlet of the fuel cell 56 is fixedly connected to the first water pipe 51, the other end of the first water pipe 51 is penetrated and connected with the water pipe 53, and the other side of the water pipe 53 is fixedly connected to the second water pipe 54, a first water pump 55 is provided on one side of the ion resin exchanger 3, the first water pump 55 is fixedly connected to the cabinet 2 and the input end of the first water pump 55 is fixedly connected to the other end of the second water pipe 54, the output end of the first water pump 55 is connected to the ion resin exchanger 3 pipeline, the upper end of the ion resin exchanger 3 is fixedly connected to the reflux pipe 44 and the other end of the reflux pipe 44 is penetrated and connected to the electrolytic tank 4.
[0027] Specifically, the charging socket 43 is used to charge the anti-leakage mechanism 8. After hydrogen and oxygen enter the fuel cell 56, hydrogen undergoes an oxidation reaction under the action of the anode catalyst and decomposes into hydrogen ions and electrons. The electrons generated by the decomposition of hydrogen flow to the cathode through an external circuit to form a current, thereby generating electrical energy. This electrical energy can be output through the power generation end. The power generation end of the fuel cell 56 is used to provide power to the first water pump 55, the second water pump 72, the third water pump 74 and the charging socket 43. At the cathode, oxygen undergoes a reduction reaction under the action of the cathode catalyst. Oxygen combines with hydrogen ions and electrons to generate chemical reaction water. The first water pump 55 starts The chemical reaction water is automatically extracted, and the chemical reaction water is discharged from the water outlet and enters the ion resin exchanger 3 through the first water pipe 51, the water pipe 53 and the second water pipe 54 in sequence. The chemical reaction water is transmitted from bottom to top. When water containing cations passes through the cation exchange resin, the cations in the water will be adsorbed by the resin. When water containing anions passes through the anion exchange resin, the anions in the water will be adsorbed by the resin, thereby effectively removing the ions in the water. After the water quality is further purified, it returns to the inside of the electrolysis tank 4 through the reflux pipe 44, so that electrolysis is carried out again, thereby completing the cyclic electrolysis of water without the need for manual water addition.
[0028] A first liquid inlet and a first liquid outlet are respectively provided on one side of the heat exchanger 7, a second liquid inlet and a second liquid outlet are respectively provided on the upper side of the heat exchanger 7, a second water pump 72 and a third water pump 74 are respectively fixedly connected to the upper side of the water tank 6, an input end of the third water pump 74 is connected to the output end pipeline of the water tank 6, an output end of the third water pump 74 is connected to the first liquid inlet pipeline of the heat exchanger 7, and the first liquid outlet of the heat exchanger 7 is connected to the input end pipeline of the water tank 6.
[0029] Specifically, the third water pump 74 is used to pump the water inside the water tank 6 into the heat exchanger 7. The heat exchanger 7 is used to perform heat exchange on the water at room temperature inside the water tank 6, thereby converting the water entering the heat exchanger 7 into hot water, which returns to the inside of the water tank 6 again, thereby circulating and heating the water inside the water tank 6.
[0030] A water channel 521 is provided inside the heat sink 52, and the output end of the water channel 521 is fixedly connected to the first cooling water pipe 58, and the other end of the first cooling water pipe 58 is fixedly connected to the second liquid inlet of the heat exchanger 7. The water pipe 53 is provided on the outside of the first cooling water pipe 58, and the upper and lower ends of the water pipe 53 are both closed. Two guide plates 57 are fixedly connected to the outside of the first cooling water pipe 58, and the other sides of the two guide plates 57 are fixedly connected to the inner wall of the water pipe 53. The two guide plates 57 divide the inner wall of the water pipe 53 into a downstream chamber and an upstream chamber, and the lower parts of the downstream chamber and the upstream chamber are connected to each other.
[0031] Specifically, since the fuel cell 56 will generate high temperature during the reaction, the cooling water circulating inside the water path 521 cools down the fuel cell 56. The cooling water exchanges heat with the heat generated by the fuel cell 56, thereby taking away the heat generated by the fuel cell 56. At this time, the fuel cell 56 is cooled down, and the cooling water is heated up to become high-temperature water. The high-temperature water passes through the first cooling water pipe 58 to reach the inside of the heat exchanger 7, and again exchanges heat with the water drawn from the water tank 6. At this time, the heat inside the high-temperature water is taken away by the water drawn from the water tank 6, and becomes low temperature again, and returns to the inside of the water path 521. The water drawn from the water tank 6 obtains heat and becomes high-temperature water, and returns to the inside of the water tank 6, thereby indirectly utilizing the heat generated by the chemical reaction of the fuel cell 56 to heat the water source inside the water tank 6, thereby conveniently providing domestic hot water.
[0032] The input end of the second water pump 72 is fixedly connected to the third cooling water pipe 73, the other end of the third cooling water pipe 73 is fixedly connected to the second liquid outlet of the heat exchanger 7, the output end of the second water pump 72 is fixedly connected to the second cooling water pipe 71, and the other end of the second cooling water pipe 71 is fixedly connected to the input end of the water path 521.
[0033] Specifically, the cooling water circulating inside the water path 521 cools down the fuel cell 56, and is heated to high-temperature water after obtaining heat. Since it needs to enter the heat exchanger 7 through the first cooling water pipe 58, the heat of the high-temperature water will be lost when passing through the first cooling water pipe 58, causing the temperature of the high-temperature water to gradually decrease, thereby causing the subsequent heat exchange efficiency between the high-temperature water and the water drawn from the water tank 6 to decrease, and further causing the water drawn from the water tank 6 to be unable to rise to the required temperature. Therefore, when the first cooling water pipe 58 transmits the high-temperature water, the high-calorie chemical reaction water reaches the upstream chamber through the first water delivery pipe 51, and the upstream chamber transports the high-calorie chemical reaction water from top to bottom, so that the high-temperature water is heated to a high temperature. The hot chemical reaction water completely contacts the semicircle on one side of the first cooling water pipe 58, and insulates the high-temperature water inside the semicircle on one side of the first cooling water pipe 58 to prevent heat loss. When the high-calorie chemical reaction water reaches the bottom of the water pipe 53, the high-calorie chemical reaction water enters the upstream chamber and is driven to be transported from bottom to top, so that the high-calorie chemical reaction water completely contacts the other semicircle on the first cooling water pipe 58, and insulates the high-temperature water inside the other semicircle on the first cooling water pipe 58 to prevent heat loss. Until the high-calorie chemical reaction water reaches the top of the water pipe 53, the chemical reaction water with reduced heat enters the second water pipe 54.
[0034] By transporting high-calorie chemical reaction water into the ion resin exchanger 3, not only can the ions of the chemical reaction water be removed, so that the chemical reaction water can be purified and then re-enter the electrolysis tank 4 to perform cyclic electrolysis of the water, but also the entire first cooling water pipe 58 can be wrapped during the transportation process to insulate the high-temperature water that is about to enter the heat exchanger 7, effectively preventing the high-temperature water from losing heat when passing through the first cooling water pipe 58, thereby causing the subsequent heat exchange efficiency between the high-temperature water and the water extracted from the water tank 6 to decrease, achieving a high energy utilization effect, and after the high-calorie chemical reaction water is insulated, the heat inside the chemical reaction water will be quickly lost, thereby reducing the temperature of the chemical reaction water, effectively preventing the subsequent ion resin exchanger 3 from being subjected to large thermal stress, resulting in a decrease in the performance of the equipment materials.
[0035] Embodiment 2: Hydrogen molecules are extremely small and can easily penetrate into the metal lattice, reacting with the carbon element in the metal to generate methane, causing microcracks inside the metal, and eventually reducing the strength of the pipeline and causing it to rupture, thereby causing hydrogen to leak into the air. Personnel are unable to detect the hydrogen leakage and shut off the gas source in time. When the volume concentration of hydrogen in the air reaches 4% to 75%, it can explode when exposed to open flames, high temperatures or static sparks, causing serious safety accidents. Therefore, the following structure is designed to solve the above technical problems.
[0036] See also Figure 8-Figure 12The anti-leakage mechanism 8 includes an anti-leakage disk 81 arranged on the outside of the hydrogen pipe 42. The interior of the anti-leakage disk 81 is respectively provided with a transmission component 82 for driving the anti-leakage mechanism 8 to perform adaptive sliding monitoring on the raised surface of the hydrogen pipe 42 and a pressing edge component 83 for sealing the edges around the leakage area using the leaking hydrogen pressure. A plug-in ring 84 is fixedly connected to one side of the anti-leakage disk 81.
[0037] Specifically, the plug-in ring 84 is used to be inserted into the charging socket 43 to charge the power storage box 826. The power storage box 826 is used to provide power to the motor 825. The transmission assembly 82 is used to drive the leak-proof disk 81 to slide on the uneven surface of the hydrogen pipe 42. The edge pressing assembly 83 is used to block the leaking area on the surface of the hydrogen pipe 42.
[0038] The transmission assembly 82 includes a guide slide 823 fixedly connected to the outside of the leak-proof disk 81, a first spring 824 is fixedly connected inside the guide slide 823, a slider 822 is fixedly connected to the other end of the first spring 824, the slider 822 is slidably connected to the inside of the leak-proof disk 81, a motor 825 is fixedly connected to the other side of the slider 822, a first roller 821 is fixedly connected to the output end of the motor 825, a power storage box 826 is provided on one side of the motor 825, the power storage box 826 is fixedly connected to the leak-proof disk 81, three second springs 828 are evenly fixedly connected inside the leak-proof disk 81, the other end of each second spring 828 is fixedly connected to a U-shaped plate 827, the internal bearing of the U-shaped plate 827 is connected to a second roller 829, the first roller 821 and the second roller 829 are slidably connected to the hydrogen pipe 42.
[0039] Specifically, when hydrogen is transported in a pipeline, hydrogen molecules will dissociate on the inner wall of the pipeline to form hydrogen atoms that are adsorbed on the surface of the pipeline wall. These hydrogen atoms will diffuse into the interior of the pipeline material and gather at defects, grain boundaries, dislocations and the like in the material. When hydrogen atoms gather to a certain extent in a local area, hydrogen molecules will be formed, generating local internal pressure, causing the material to expand locally to form bubbles, causing some areas of the pipeline surface to bulge, and the bulging areas will jam the wheels, preventing the leak-proof disc 81 from sliding on the surface of the hydrogen pipe 42.
[0040] The rotation of the output end of the motor 825 is used to control the rotation of the first roller 821, so that the first roller 821 rubs against the surface of the hydrogen pipe 42, and then the leak-proof disc 81 slides on the surface of the hydrogen pipe 42, and indirectly drives the three second rollers 829 to roll for auxiliary sliding. When the first roller 821 or the second roller 829 presses onto the raised area of the hydrogen pipe 42, the corresponding first spring 824 or the second spring 828 is compressed, so that the first roller 821 and the second roller 829 adapt to the raised area of the hydrogen pipe 42 to roll, effectively preventing the first roller 821 and the second roller 829 from getting stuck, causing the leak-proof disc 81 to be unable to move.
[0041] The edge pressing assembly 83 includes four detection grooves 831 arranged inside the leak-proof disk 81, and a gas sensor 836 is fixedly connected inside each detection groove 831. Each detection groove 831 is provided with a slide groove 832 on four sides, and one side of the slide groove 832 is connected to a ventilation groove 833. A slide plate 835 is slidably connected inside the ventilation groove 833, and a rubber block 834 is fixedly connected to the other side of the slide plate 835. The other side of the rubber block 834 is in contact with the outer side of the hydrogen pipe 42, and one side of the rubber block 834 is pressed against the inner wall of the leak-proof disk 81.
[0042] Specifically, the four gas sensors 836 are used to detect hydrogen in four different directions respectively. The gas sensor 836 can be an infrared gas sensor. The infrared gas sensor is a sensor that uses infrared absorption spectroscopy technology to detect gas concentration. It measures the gas concentration based on the principle that different gas molecules have different absorption characteristics for infrared light of a specific wavelength. When the infrared gas sensor detects a hydrogen leak, the infrared gas sensor transmits a signal to the solar panel 1 to stop powering it, thereby stopping the electrolysis of water.
[0043] However, when the electrolysis of water stops, there is still some untransmitted hydrogen inside the hydrogen pipe 42, and the leak is still leaking the remaining hydrogen. Therefore, the infrared gas sensor transmits a signal to the output end of the motor 825 while transmitting a signal to the solar panel 1, and the output end of the motor 825 stops rotating, and the first roller 821 and the second roller 829 stop moving, so that the anti-leakage plate 81 stops sliding.
[0044] The contact area between hydrogen and the slide plate 835 is larger than the contact area between hydrogen and the rubber block 834. When hydrogen is leaking, the rubber block 834 is in contact with the surface of the hydrogen pipe 42, and hydrogen continues to leak into the inside of the round-shaped rubber block 834. As hydrogen continues to enter, the internal pressure of the round-shaped rubber block 834 increases. Under the push of the high-pressure hydrogen, the round-shaped rubber block 834 may turn inside out, causing hydrogen to leak again. Therefore, when the internal pressure of the round-shaped rubber block 834 increases, the airflow thrust generated by the leakage port continuously pushes the leaked hydrogen to the vicinity of the ventilation groove 833, and the internal pressure of the rubber block 834 and the ventilation groove 833 increases, and the hydrogen The vent groove 833 generates a direct thrust on the slide plate 835, and the slide plate 835 slides along the slide groove 832, generating an extrusion force on the rubber block 834, thereby increasing the pressing force of the rubber block 834 on the surface of the hydrogen pipe 42, and preventing the internal pressure of the rubber block 834 from being too high and causing the rubber block 834 to turn inside out. Since the friction between the slide plate 835 and the slide groove 832 is small, the rubber block 834 needs to overcome the friction between the rubber block 834 and the outer wall of the pipe and the elastic resistance of the rubber block 834 itself in order to turn inside out. These resistances are relatively large, resulting in a larger air pressure difference for the rubber block 834 to turn inside out. Therefore, the rubber block 834 will not turn inside out before the slide plate 835 slides.
[0045] The motor 825 controls the first roller 821 and the second roller 829 to rotate, thereby indirectly driving the leak-proof disc 81 to slide on the uneven surface of the hydrogen pipe 42. During the sliding process, the rubber block 834 always fits the surface of the hydrogen pipe 42, and the gas sensor 836 detects the surface of the hydrogen pipe 42 in real time. When leakage occurs, the motor 825 controls the leak-proof disc 81 to stop moving, and the rubber block 834 covers the leakage area, controls the solar panel 1 to stop power supply, and starts to collect the remaining hydrogen inside the hydrogen pipe 42. When the air pressure inside the rubber block 834 and the ventilation groove 833 gradually increases, the hydrogen generates a large thrust on the slide plate 835, driving the slide plate 835 to slide along the slide groove 832, generating an extrusion force on the rubber block 834. At this time, the pressing force of the rubber block 834 on the surface of the hydrogen pipe 42 increases, effectively preventing the internal pressure of the rubber block 834 from being too high, causing the rubber block 834 to turn outward, thereby causing the hydrogen to leak again, thereby achieving a high protective effect.
