Description

Technical Field

[0001] The present invention relates to the technical field of energy utilization, and particularly to a green hydrogen production and combined heat and power supply device based on solar energy conversion. Background Art

[0002] Producing green hydrogen from solar energy is a technology that uses solar energy to decompose water into hydrogen and oxygen, which has the advantages of being clean, renewable, and having zero carbon emissions, and 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 and convert light energy into electrical energy. The electrolyzer is used to electrolyze water with the electrical energy. Water molecules are decomposed into hydrogen and oxygen in the electrolyzer. The electrolyzer usually consists of an anode, a cathode, and an electrolyte. Under the action of an electric field, water molecules lose electrons at the anode and undergo an oxidation reaction to generate oxygen, while at the cathode, they gain electrons and undergo a reduction reaction to generate hydrogen.

[0004] Hydrogen combined heat and power supply 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 overall energy utilization rate can generally reach more than 90%.

[0005] After high-temperature water is generated by the chemical reaction of hydrogen and oxygen, the staff will store the generated high-temperature water centrally and then discharge it into the environment separately. Discharging the high-temperature water that has undergone a chemical reaction will not only affect the surrounding environment, but also reduce the utilization rate of the heat energy of the high-temperature water, resulting in waste of resources. Moreover, the discharge of high-temperature water may cause the equipment to bear greater thermal stress, leading to a decline in the performance of the equipment materials, and even problems such as cracks and deformation.

[0006] Therefore, it is necessary to design a green hydrogen production and combined heat and power supply device based on solar energy conversion with high energy utilization rate. Summary of the Invention

[0017] According to the above technical solution,

[0018] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0019] 1. By sending high-calorie chemical reaction water into the ion resin exchanger, not only can the ions in the chemical reaction water be removed, enabling the purified chemical reaction water to re-enter the electrolysis tank for the cyclic electrolysis of water, but also during the transportation process, the entire first cooling water pipe can be wrapped to keep the high-temperature water about to enter the heat exchanger warm. This effectively prevents the loss of heat from the high-temperature water when it passes through the first cooling water pipe, thus avoiding the phenomenon of reduced heat exchange efficiency between the subsequent high-temperature water and the water pumped from the water tank, achieving a high energy utilization rate. Moreover, after the high-calorie chemical reaction water keeps the high-temperature water warm, the heat inside the chemical reaction water will quickly dissipate, thereby reducing the temperature of the chemical reaction water and effectively preventing the subsequent ion resin exchanger from suffering from excessive thermal stress, which may lead to a decline in the material properties of the equipment.

[0020] 2. By controlling the rotation of the first roller and the second roller with a motor, the anti-leakage plate is indirectly driven to slide on the uneven surface of the hydrogen pipe. During the sliding process, the rubber block always adheres to the surface of the hydrogen pipe, and the gas sensor continuously detects the surface of the hydrogen pipe. When leakage occurs, the motor controls the anti-leakage plate to stop moving, and the rubber block covers the leakage area. The solar panel is controlled to stop power supply, and the remaining hydrogen inside the hydrogen pipe is collected. Moreover, when the air pressure inside the rubber block and the ventilation groove gradually increases, the hydrogen generates a large thrust on the slide plate, driving the slide plate to slide along the chute and exerting 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, effectively preventing the rubber block from turning out due to excessive internal pressure, which may cause the hydrogen to leak again, achieving a high level of protection.

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0041] Please refer to Figures 1-12 , the present invention provides a technical solution: a green hydrogen production and combined heat and power supply device based on solar energy conversion, including a cabinet body 2. A solar panel 1 is provided on one side of the cabinet body 2. An electrolysis tank 4 for electrolyzing circulating water is fixedly connected inside the cabinet body 2. An electrolysis cell is provided inside the electrolysis tank 4. The solar panel 1 is used to convert light energy into electrical energy to supply power to the electrolysis cell. 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 to the upper side of the water tank 6. A reaction mechanism 5 for producing electrical energy and heat energy is provided on the upper side of the heat exchanger 7. An ion resin exchanger 3 for removing impurities and ions from the chemical reaction water generated by the reaction mechanism 5 is provided on one side of the reaction mechanism 5.

[0042] Specifically, the solar panel 1 absorbs solar energy and converts it into electrical energy. The solar panel 1 is usually composed of multiple solar cells. When these cells are irradiated by sunlight, an electric current will be generated due to the photovoltaic 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. Usually, an anode and a cathode are provided inside the electrolysis tank 4, and 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, water molecules undergo an oxidation reaction to generate oxygen, hydrogen ions, and electrons. At the cathode, hydrogen ions gain electrons and undergo a reduction reaction to generate hydrogen.

[0043] Please refer to Figure 3 , an oxygen output end and a hydrogen output end are respectively provided on the upper side of the electrolysis tank 4. The oxygen output end and the hydrogen output end are respectively fixedly connected with an oxygen pipe 41 and a hydrogen pipe 42. An anti-leakage mechanism 8 for preventing hydrogen leakage is provided on the outer side of the hydrogen pipe 42.

[0044] Specifically, the hydrogen and oxygen generated by the electrolysis of the electrolysis tank 4 are respectively discharged from the electrolysis tank through the hydrogen pipe 42 and the oxygen pipe 41. The anti-leakage mechanism 8 is used to slide on the surface of the pipeline, monitor in real time whether the pipeline is leaking, and stop moving when the pipeline leaks, and use the leaked hydrogen flow to block the leakage point.

[0045] Please refer to Figures 3-7, the reaction mechanism 5 includes a heat dissipation plate 52 fixedly connected to the inside of the cabinet body 2. Inside the heat dissipation plate 52, a fuel cell 56 is fixedly connected. An oxygen input end, a hydrogen input end, a power generation end, and a water output end are respectively arranged outside 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 output end of the fuel cell 56 is fixedly connected to a first water pipe 51. The other end of the first water pipe 51 is connected through a water guide pipe 53. The other side of the water guide pipe 53 is fixedly connected to a second water pipe 54. A first water pump 55 is arranged on one side of the ion exchange resin device 3. The first water pump 55 is fixedly connected to the cabinet body 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 exchange resin device 3 through a pipeline. The upper end of the ion exchange resin device 3 is fixedly connected to a return pipe 44, and the other end of the return pipe 44 penetrates and is connected to the electrolysis tank 4.

[0046] Specifically, the charging socket 43 is used to charge the leakage prevention mechanism 8. After hydrogen and oxygen enter the fuel cell 56, hydrogen undergoes an oxidation reaction under the action of an anode catalyst, decomposing into hydrogen ions and electrons. The electrons generated by the decomposition of hydrogen flow through an external circuit to the cathode, forming an electric 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 for 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 a cathode catalyst. Oxygen combines with hydrogen ions and electrons to generate chemical reaction water. The first water pump 55 starts to pump it. The chemical reaction water is discharged from the water output end and sequentially enters the ion exchange resin device 3 through the first water pipe 51, the water guide pipe 53, and the second water pipe 54. The chemical reaction water is transmitted from bottom to top. When the water containing cations passes through the cation exchange resin, the cations in the water will be adsorbed by the resin. When the 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 return pipe 44, and then electrolysis is carried out again, thus completing the cyclic electrolysis of water without manual water addition by personnel.

[0047] A first liquid inlet and a first liquid outlet are respectively arranged on one side of the heat exchanger 7. A second liquid inlet and a second liquid outlet are respectively arranged 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. The input end of the third water pump 74 is connected to the output end of the water tank 6 through a pipeline. The output end of the third water pump 74 is connected to the first liquid inlet of the heat exchanger 7 through a pipeline. The first liquid outlet of the heat exchanger 7 is connected to the input end of the water tank 6 through a pipeline.

[0048] 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 normal-temperature water inside the water tank 6, so as to convert the water entering the heat exchanger 7 into hot water and then return it to the inside of the water tank 6, thereby circularly heating the water inside the water tank 6.

[0049] A water path 521 is provided inside the heat dissipation plate 52. The output end of the water path 521 is fixedly connected to a first cooling water pipe 58. The other end of the first cooling water pipe 58 is fixedly connected to the second liquid inlet of the heat exchanger 7. A guide water pipe 53 is arranged outside the first cooling water pipe 58. The upper and lower ends of the guide water pipe 53 are both closed. Two flow guide plates 57 are fixedly connected to the outside of the first cooling water pipe 58, and the other sides of the two flow guide plates 57 are fixedly connected to the inner wall of the guide water pipe 53. The two flow guide plates 57 divide the inner wall of the guide water pipe 53 into a downstream chamber and an upstream chamber, and the lower parts of the downstream chamber and the upstream chamber are communicated with each other.

[0050] Specifically, since the fuel cell 56 generates 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 reaches the inside of the heat exchanger 7 through the first cooling water pipe 58 and performs heat exchange on the water pumped from the inside of the water tank 6 again. At this time, the heat inside the high-temperature water is taken away by the water pumped from the inside of the water tank 6 and becomes low temperature again, and then returns to the inside of the water path 521. The water pumped from the inside of the water tank 6 obtains heat and becomes high-temperature water and then returns to the inside of the water tank 6, thereby indirectly using the heat generated by the chemical reaction of the fuel cell 56 to heat the water source inside the water tank 6, and thus facilitating the provision of domestic hot water.

[0051] The input end of the second water pump 72 is fixedly connected to a 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 a 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.

[0052] Specifically, the cooling water circulating inside the water channel 521 cools down the fuel cell 56 and then heats up to high-temperature water after obtaining heat. Since it needs to enter the heat exchanger 7 through the first cooling water pipe 58, when passing through the first cooling water pipe 58, heat loss of the high-temperature water will occur, gradually reducing the temperature of the high-temperature water, which in turn leads to a decrease in the heat exchange efficiency between the subsequent high-temperature water and the water extracted from the water tank 6, and further causes the water extracted from the water tank 6 to fail to reach the required temperature. Therefore, when the first cooling water pipe 58 transports the high-temperature water, the high-calorie chemical reaction water reaches the upper flow chamber through the first water delivery pipe 51. The upper flow chamber transports the high-calorie chemical reaction water from top to bottom, enabling the high-calorie chemical reaction water to fully contact the semi-circle on one side of the first cooling water pipe 58, insulating the high-temperature water inside the semi-circle on one side of the first cooling water pipe 58 to prevent heat loss. When the high-calorie chemical reaction water reaches the bottom inside the water guide pipe 53, the high-calorie chemical reaction water enters the upper flow chamber and is driven to be transported from bottom to top, enabling the high-calorie chemical reaction water to fully contact the semi-circle on the other side of the first cooling water pipe 58, insulating the high-temperature water inside the semi-circle on the other side of the first cooling water pipe 58 to prevent heat loss. Until the high-calorie chemical reaction water reaches the top inside the water guide pipe 53, the chemical reaction water with reduced heat enters the second water delivery pipe 54.

[0053] By transporting the high-calorie chemical reaction water into the ion resin exchanger 3, not only can the ions of the chemical reaction water be removed, enabling the chemical reaction water to be purified and then enter the electrolysis tank 4 again for cyclic electrolysis of water, but also during the transportation process, the entire first cooling water pipe 58 can be wrapped to insulate the high-temperature water about to enter the heat exchanger 7, effectively preventing heat loss of the high-temperature water when passing through the first cooling water pipe 58, which would otherwise lead to a decrease in the heat exchange efficiency between the subsequent high-temperature water and the water extracted from the water tank 6, achieving the effect of high energy utilization rate. Moreover, after the high-calorie chemical reaction water insulates the high-temperature water, the heat inside the chemical reaction water will quickly dissipate, thereby reducing the temperature of the chemical reaction water, effectively preventing the subsequent ion resin exchanger 3 from suffering from excessive thermal stress, which would cause a decline in the material properties of the equipment.

[0054] In Embodiment 2, hydrogen molecules are extremely small and easily penetrate into the metal lattice, reacting with the carbon element in the metal to form methane, resulting in the generation of microcracks inside the metal, ultimately causing the pipeline strength to decline and rupture, thereby allowing hydrogen to leak into the air. Personnel cannot promptly detect the hydrogen leakage and close the gas source. When the volume concentration of hydrogen in the air reaches 4% - 75%, it can explode when encountering an open flame, high temperature, or static electric spark, causing serious safety accidents. Therefore, the following structure is designed to solve the above technical problems.

[0055] Please refer to Figures 8-12, the anti-leakage mechanism 8 includes a leak-proof plate 81 provided outside the hydrogen pipe 42. Inside the leak-proof plate 81, there are respectively a transmission component 82 for driving the anti-leakage mechanism 8 to slide adaptively on the surface of the convex hydrogen pipe 42 for monitoring, and a pressing component 83 for using the leaked hydrogen pressure to seal the periphery of the leakage area. One side of the leak-proof plate 81 is fixedly connected with a plug-in ring 84.

[0056] Specifically, the plug-in ring 84 is used to insert into the charging socket 43 to charge the electricity storage box 826. The electricity storage box 826 is used to provide power for the motor 825. The transmission component 82 is used to drive the leak-proof plate 81 to slide on the uneven surface of the hydrogen pipe 42, and the pressing component 83 is used to block the leaked area on the surface of the hydrogen pipe 42.

[0057] The transmission component 82 includes a guide slide plate 823 fixedly connected to the outside of the leak-proof plate 81. Inside the guide slide plate 823, there is a first spring 824 fixedly connected. The other end of the first spring 824 is fixedly connected with a slider 822. The slider 822 is slidably connected inside the leak-proof plate 81. On the other side of the slider 822, there is a motor 825 fixedly connected. The output end of the motor 825 is fixedly connected with a first roller 821. There is an electricity storage box 826 on one side of the motor 825. The electricity storage box 826 is fixedly connected with the leak-proof plate 81. Three second springs 828 are evenly and fixedly connected inside the leak-proof plate 81. The other end of each second spring 828 is fixedly connected with a U-shaped plate 827. Inside the U-shaped plate 827, there is a second roller 829 connected by a bearing. The first roller 821 and the second roller 829 are slidably connected with the hydrogen pipe 42.

[0058] Specifically, when hydrogen is transported in the pipeline, hydrogen molecules will dissociate on the inner wall of the pipeline to form hydrogen atoms and adsorb on the pipe wall surface. These hydrogen atoms will diffuse into the interior of the pipeline material and accumulate at positions such as material defects, grain boundaries, and dislocations. When the hydrogen atoms accumulate to a certain extent in a local area, hydrogen molecules will be formed, generating local internal pressure, causing local expansion of the material to form bulges, making some areas on the pipeline surface bulge. The bulging areas will jam the wheels and prevent the leak-proof plate 81 from sliding on the surface of the hydrogen pipe 42.

[0059] 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 plate 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 on the bulging area of the hydrogen pipe 42, the corresponding first spring 824 or second spring 828 is compressed, so that the first roller 821 and the second roller 829 can roll to adapt to the bulging area of the hydrogen pipe 42, effectively preventing the phenomenon that the first roller 821 and the second roller 829 are jammed and the leak-proof plate 81 cannot move.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] The contact area between hydrogen and the skateboard 835 is larger than that between hydrogen and the rubber block 834. In the state of hydrogen leakage, the rubber block 834 fits against the surface of the hydrogen pipe 42, and hydrogen continuously leaks into the internal of the loop-shaped rubber block 834. As hydrogen continuously enters, the internal air pressure of the loop-shaped rubber block 834 becomes higher. Under the push of high-pressure hydrogen, the loop-shaped rubber block 834 may turn outwards, causing hydrogen to leak again. Therefore, during the process of the internal air pressure of the loop-shaped rubber block 834 becoming higher, the air flow thrust generated at the leakage port continuously pushes the leaked hydrogen to the periphery of the ventilation groove 833. The air pressure inside the rubber block 834 and the ventilation groove 833 becomes higher, and hydrogen gas generates a direct thrust on the skateboard 835 through the ventilation groove 833. The skateboard 835 slides along the chute 832, generating an extrusion force on the rubber block 834, increasing the pressing force of the rubber block 834 against the surface of the hydrogen pipe 42, preventing the rubber block 834 from turning outwards due to excessive internal pressure. Since the friction between the skateboard 835 and the chute 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 when turning outwards. These resistances are large, resulting in a larger air pressure difference required for the rubber block 834 to turn outwards. Therefore, the rubber block 834 will not turn outwards in advance before the skateboard 835 slides.

[0064] The motor 825 is used to control the rotation of the first roller 821 and the second roller 829, indirectly driving the leakage prevention plate 81 to slide on the uneven surface of the hydrogen pipe 42. During the sliding process, the rubber block 834 always fits against the surface of the hydrogen pipe 42. The gas sensor 836 continuously detects the surface of the hydrogen pipe 42. When air leakage occurs, the motor 825 controls the leakage prevention plate 81 to stop moving, and the rubber block 834 covers the air leakage area, controls the solar panel 1 to stop power supply, and starts to collect the remaining hydrogen inside the hydrogen pipe 42. And when the air pressure inside the rubber block 834 and the ventilation groove 833 gradually increases, hydrogen generates a large thrust on the skateboard 835, driving the skateboard 835 to slide along the chute 832, generating an extrusion force on the rubber block 834. At this time, the pressing force of the rubber block 834 against the surface of the hydrogen pipe 42 increases, effectively preventing the rubber block 834 from turning outwards due to excessive internal pressure, thus preventing the phenomenon of hydrogen leaking again, achieving a high protection effect.
