Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen energy storage, and in particular to a hydrogen supply and energy storage device. Background Art

[0002] With the increasing demand for clean energy, hydrogen, as an efficient and clean energy carrier, has received extensive attention in the field of energy storage. Hydrogen energy storage devices can achieve energy storage and release, providing support for the stable supply of renewable energy.

[0003] For current energy storage devices, in an existing hydrogen energy storage device and its hydrogen energy storage method disclosed in the patent number "CN118998600B", it enters the interior of the heat exchange tube through a tee tube. When the rotating motor starts, it drives the heat exchange fan installed at its output end to rotate. When the heat exchange fan rotates, the air flow will come into contact with the outer surface of the heat exchange tube, and the heat energy generated by the hydrogen in the heat exchange tube is carried away by the generated air flow. During the operation of this device, as hydrogen continuously flows into the heat exchange tube, the heat carried by the hydrogen itself will gradually be transferred to the inner wall of the heat exchange tube, thereby causing a significant increase in the surface temperature of the heat exchange tube. In this case, the air flow generated by the heat exchange fan is difficult to fully dissipate the heat on the surface of the heat exchange tube. Since the heat on the surface of the heat exchange tube cannot be dissipated in a timely and effective manner, it is difficult for the heat of the hydrogen in the tube to be conducted to the outside through the tube wall, resulting in ineffective heat dissipation treatment of the hydrogen. This situation will have an adverse impact on the condensation effect of the device and reduce the condensation efficiency.

[0004] Accordingly, this application proposes a hydrogen supply and energy storage device. Summary of the Invention

[0044] 1. By setting up a heat dissipation circulation component, the motor drives the first sector gear to rotate.

The second sector gear meshes with the rack, causing the rack to reciprocate. The telescopic airbag is driven to expand and contract through the fixed rod, sucking air into the gas storage tank and then spraying it out through the air delivery pipe, the transfer pipe and the nozzle to blow and clean the metal heat dissipation fins, removing dust and ensuring the good heat dissipation performance of the heat dissipation components.

[0046] 3. By setting up a waste heat storage shell and a spiral heating belt, the heat during the cooling process of gaseous hydrogen can be recovered to avoid waste of thermal energy. The recovered heat is stored in the waste heat storage shell and then, through cooperation with the spiral heating belt, the liquid hydrogen in the conversion pipe can repeatedly absorb heat and gradually undergo a phase change, and finally be completely converted into gaseous hydrogen and enter the gaseous hydrogen storage tank, realizing the efficient utilization of energy.

Detailed implementation manners

[0058] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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 of the embodiments.

[0059] Embodiment 1:

[0060] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4, a hydrogen supply and energy storage device, including a hydrogen storage tank body 1. Inside the hydrogen storage tank body 1, a gaseous hydrogen storage tank 2 is installed. One end of the hydrogen storage tank body 1 is connected to an intake three-way pipe 3, and the intake three-way pipe 3 communicates with the gaseous hydrogen storage tank 2. An air outlet 4 is opened at the bottom of the gaseous hydrogen storage tank 2, and a spiral compressor 5 is installed at the bottom end of the gaseous hydrogen storage tank 2. The air outlet communicates with the intake port of the spiral compressor 5. A hydrogen delivery pipe 6 is connected to the spiral compressor 5. A support plate 7 is fixedly connected to the hydrogen storage tank body 1. At the top of the support plate 7, a coolant storage tank 8 is installed. A transverse plate 9 is fixedly connected to the side wall of the coolant storage tank 8. The height of the transverse plate 9 is the same as the height of the metal heat dissipation fins 801, and the spray head 913 and the transfer pipe 912 are arranged on the inner side wall of the transverse plate 9, so that the spray head 913 directly aims at the gaps in the metal heat dissipation fins 801. When the air blowing and cleaning assembly is started, the spray head 913 sprays out a strong and concentrated air flow, which can quickly and effectively penetrate into the gaps in the metal heat dissipation fins 801. These gaps are often areas where dust and impurities are extremely likely to accumulate, and the precise aiming of the spray head 913 enables the air flow to fully play its role, blowing the dust in the gaps away completely, avoiding the problem of reduced heat dissipation efficiency caused by dust accumulation.

[0061] The side wall of the transverse plate 9 is provided with metal heat dissipation fins 801. The metal heat dissipation fins 801 are made of high-purity aluminum material and have an extremely high heat conduction coefficient, which can quickly transfer heat to the air. The metal heat dissipation fins 801 are arranged in two layers up and down. The heat of the coolant in the coolant storage tank 8 is absorbed by the metal heat dissipation fins 801 at the bottom and transferred to the metal heat dissipation fins 801 at the top to be dissipated into the surrounding air, thus achieving a rapid cooling effect on the coolant storage tank 8.

[0062] A connecting plate 10 is fixedly connected to the bottom end of the spiral compressor 5. The spiral compressor 5 is composed of a male rotor and a female rotor, a housing, bearings, a sealing device and a synchronous gear. It rotates through the rotor. The teeth of the male rotor and the female rotor gradually mesh with each other, so that the volume between the teeth continuously decreases. The hydrogen enclosed in the volume between the teeth is compressed, and the pressure and temperature gradually increase. Due to the special tooth profile design of the rotor, the compression process is relatively continuous and stable, and the gas is gradually compressed in the volume between the teeth. This spiral compressor 5 belongs to the prior art in this field, and the internal structure of this spiral compressor 5 is one of the prior arts, only included and not unique. Specific selection needs to be based on actual situations, so it will not be described in detail.

[0063] A fan 11 is installed on the connecting plate 10. An infrared temperature sensor is installed on the connecting plate 10. When infrared rays radiate onto the cooling pipe, the detector absorbs the infrared energy and its own temperature rises. Due to the special physical properties of the thermosensitive material inside it, the change in temperature will cause a change in the charge on the surface of the material, thereby converting the energy of the infrared radiation into an electrical signal charge or voltage signal to control the start of the motor, which drives the heat dissipation circulation component to work and dissipate heat from the cooling pipe.

[0064] At one end of the connecting plate 10 away from the screw compressor 5, a piston compressor 12 is installed. The piston compressor 12 communicates with the hydrogen delivery pipe 6. A hydrogen transport pipe 13 is connected to the side wall of the piston compressor 12. The piston compressor 12 consists of a piston assembly, a cylinder, a valve, a lubrication system and a lubrication system. When the piston starts to move upward from the bottom dead center, the space inside the cylinder gradually decreases and the hydrogen is compressed. At this time, the suction valve inside the piston compressor closes to prevent gas backflow. As the piston moves upward, the pressure and temperature of the hydrogen inside the cylinder continuously increase until the pressure inside the cylinder reaches the set discharge pressure, and the compression process ends. This piston compressor 12 belongs to the prior art in this field, and the internal structure of this piston compressor 12 belongs to one of the prior arts, only included and not unique. Specifically, it needs to be selected according to the actual situation, so it will not be described in detail.

[0065] A plate condenser 14 is installed on the hydrogen transport pipe 13. At one end of the hydrogen transport pipe 13 away from the piston compressor 12, a liquid hydrogen storage tank 15 is installed. The plate condenser 14 is fixedly connected to the liquid hydrogen storage tank 15. The plates of the plate condenser 14 are made of stainless steel material, which has good corrosion resistance and heat conduction performance. The plates are sealed by a sealing gasket, and the sealing gasket is made of fluororubber material with high temperature resistance and low temperature resistance to ensure good sealing performance. The plate condenser 14 is equipped with a cooling water system, and the heat of the hydrogen is carried away through the circulating flow of the cooling water to achieve cooling and liquefaction. This plate condenser 14 belongs to the prior art in this field, and the internal structure of this plate condenser 14 belongs to one of the prior arts, only included and not unique. Specifically, it needs to be selected according to the actual situation, so it will not be described in detail.

[0066] A hydrogen storage tank body 1 is equipped with a transfer pump 16. The transfer pump 16 communicates with a liquid hydrogen storage tank 15. A conversion pipe 17 is installed on the transfer pump 16, and a spiral heating tape 18 is installed on the conversion pipe 17. An intake valve 19 is installed on the gaseous hydrogen storage tank 2, and the intake valve 19 is inserted into the conversion pipe 17. A gas detector 20 is installed on the hydrogen storage tank body 1. The gas detector 20 consists of a sensor, a signal processing module, a microprocessor, a display module, an alarm module, a power supply module, and a housing. When a gas containing hydrogen contacts the surface of the sensor, hydrogen will chemically react with the metal oxide on the sensor surface, causing a change in the resistance value of the sensor. This change in resistance value is directly proportional to the concentration of hydrogen. The signal processing module calculates the concentration of hydrogen by detecting and analyzing the change in resistance value and converts it into a corresponding electrical signal. After further processing and conversion, the display module displays the hydrogen concentration value. When the detected hydrogen concentration exceeds a preset safety threshold, the alarm module will be immediately activated, the buzzer will emit a high-loudness sound, and the warning light will flash to remind the operator to take corresponding measures to ensure the safe operation of the device. At the same time, the detector will also send the alarm information to an external control system or monitoring device through a communication interface to achieve remote monitoring and management.

[0067] A waste heat storage shell 21 is fixedly connected to the hydrogen storage tank body 1. The waste heat storage shell 21 communicates with a connecting plate 10, and further includes a heat dissipation circulation component and a blowing and cleaning component.

[0068] In this embodiment, gaseous hydrogen enters the gaseous hydrogen storage tank 2 through an intake three-way pipe 3 for temporary storage. When the internal space of the gaseous hydrogen storage tank 2 reaches a specified range, it will flow into a spiral compressor 5 through the outlet 4 at the bottom for preliminary compression. A large amount of heat will be generated during the compression of hydrogen. The heat dissipation circulation component and a fan 11 dissipate heat from the hydrogen delivery pipe 6. The fan 11 blows the heat in the hydrogen delivery pipe 6 into the waste heat storage shell 21 for storage. When the cooled hydrogen enters a piston compressor 12 through the hydrogen delivery pipe 6 for further compression, the compressed high-temperature and high-pressure hydrogen enters a hydrogen transport pipe 13 and is cooled into liquid hydrogen by a plate condenser 14 and stored in the liquid hydrogen storage tank 15. When it is necessary to convert liquid hydrogen into gaseous hydrogen, the liquid hydrogen in the liquid hydrogen storage tank 15 is pumped to the conversion pipe 17 by the transfer pump 16. At this time, the heat recovered by the spiral heating tape 18 and the waste heat storage shell 21 is used to heat the liquid hydrogen to make it turn into gaseous hydrogen, and then it is transported to the gaseous hydrogen storage tank 2 through the intake valve 19. At the same time, the gas detector 20 on the hydrogen storage tank body 1 monitors the hydrogen concentration in real time, alarms when an abnormality occurs, and the blowing and cleaning component cleans and maintains the metal heat dissipation fins 801 to ensure its good heat dissipation performance and ensure the stable operation of the entire device.

[0069] Embodiment Two:

[0070] Different from the first embodiment, with reference to Figure 3 , Figure 4 , Figure 5 and Figure 6 , this embodiment further has the following content: The heat dissipation circulation component is used to dissipate heat from the hydrogen delivery pipe 6; The heat dissipation circulation component includes a mounting plate 81, a motor 82, a first sector gear 83, a rotating shaft 84, a transmission gear 85, an output shaft 86, a driven gear 87, a connecting rod 88, a piston rod 89, a sealing pipe 810, a cooling pipe 811, and a liquid inlet pipe 812. The mounting plate 81 is fixedly connected to the top of the coolant storage tank 8. The mounting plate 81 is hollow. The height of the mounting plate 81 is set to be lower than the top height of the metal heat dissipation fins 801. During the process of blowing and cleaning the metal heat dissipation fins 801, when the nozzle 913 sprays out strong air flow, the air flow will blow towards the surface of the metal heat dissipation fins 801 at a certain angle and speed. Since the height of the mounting plate 81 is lower than the top of the metal heat dissipation fins 801, the dust that was originally attached to the metal heat dissipation fins 801 will be quickly lifted and separated from the fin surface under the impact force of the air flow. At this time, since the top of the mounting plate 81 is inclined, the lifted dust will not disperse disorderly inside the device, but will be directly blown away from the surface of the mounting plate 81 along the direction of the air flow.

[0071] The motor 82 is fixedly connected to the side wall of the mounting plate 81. The first sector gear 83 is fixedly connected to the output end of the motor 82. One end of the rotating shaft 84 is rotatably connected to the side wall of the mounting plate 81. The rotating shaft 84 is fixedly connected to the metal heat dissipation fins 801. The other end of the rotating shaft 84 is rotatably connected to the cross plate 9. The transmission gear 85 is fixedly connected to the rotating shaft 84. The transmission gear 85 meshes with the first sector gear 83. The output shaft 86 is rotatably connected to the side wall of the coolant storage tank 8. The driven gear 87 is fixedly connected to the output shaft 86. The driven gear 87 meshes with the first sector gear 83. The connecting rod 88 is hinged to the driven gear 87. The piston rod 89 is hinged to the end of the connecting rod 88 away from the first sector gear 83. The sealing pipe 810 is hermetically sleeved on the piston rod 89. The cooling pipe 811 is connected to the end of the sealing pipe 810 away from the piston rod 89. The cooling pipe 811 communicates with the coolant storage tank 8. The liquid inlet pipe 812 is connected to the sealing pipe 810. The liquid inlet pipe 812 communicates with the coolant storage tank 8. Electromagnetic valves are provided in the suction pipe 97, the discharge pipe 99, the liquid inlet pipe 812, and the cooling pipe 811.

[0072] In this embodiment, the surface of the cooling pipe 811 is detected by a temperature sensor. When the surface temperature of the cooling pipe 811 reaches a specified value, the motor 82 is controlled to start and drive the first sector gear 83 to rotate. During the rotation of the first sector gear 83, it meshes with the transmission gear 85. Since the transmission gear 85 is fixed on the rotating shaft 84, and the rotating shaft 84 is fixedly connected to the metal heat dissipation fins 801, the rotation of the rotating shaft 84 is driven, and then the metal heat dissipation fins 801 rotate to accelerate the flow of the surrounding air to assist in heat dissipation. At the same time, the first sector gear 83 also meshes with the driven gear 87, driving the driven gear 87 to rotate around the output shaft 86. The driven gear 87 makes the piston rod 89 hinged to it perform a reciprocating linear motion in the sealed pipe 810 through the hinged connecting rod 88. When the piston rod 89 moves outward, the solenoid valve in the liquid inlet pipe 812 opens, and the coolant is sucked from the coolant storage tank 8 into the sealed pipe 810 through the liquid inlet pipe 812. When the piston rod 89 moves inward, the solenoid valve in the liquid inlet pipe 812 closes, and the solenoid valve in the cooling pipe 811 opens, and the coolant is pressed into the cooling pipe 811 and flows back to the coolant storage tank 8. In this way, the continuous reciprocating motion of the piston rod 89 makes the coolant continuously circulate among the coolant storage tank 8, the liquid inlet pipe 812, the sealed pipe 810 and the cooling pipe 811, absorbs the heat dissipated by the hydrogen delivery pipe 6 and brings it back to the coolant storage tank 8 for heat dissipation, thereby realizing effective heat dissipation for the hydrogen delivery pipe 6.

[0073] Embodiment Three:

[0074] Refer to Figure 7 , Figure 8 , Figure 9 and Figure 10, compared with the first embodiment and the second embodiment, in this embodiment, the air blowing and cleaning assembly is used to clean the dust on the metal heat dissipation fins 801. The air blowing and cleaning assembly includes a second sector gear 91, an L-shaped plate 92, a spring 93, a rack 94, a fixed rod 95, a telescopic airbag 96, an air suction pipe 97, a support plate 98, an air outlet pipe 99, a gas storage tank 910, an air supply pipe 911, a transfer pipe 912, and a spray head 913. The second sector gear 91 is fixedly connected to the rotating shaft 84. The L-shaped plate 92 is fixedly connected to the side wall of the horizontal plate 9. The spring 93 is fixedly connected to the inner side wall of the L-shaped plate 92. The rack 94 is fixedly connected to the end of the spring 93 away from the L-shaped plate 92. The rack 94 meshes with the second sector gear 91. The fixed rod 95 is fixedly connected to the end of the rack 94 away from the spring 93. The spring 93 is made of stainless steel spring steel, with high strength characteristics and excellent elastic performance. When the second sector gear 91 disengages from the rack 94, the spring 93 drives the fixed rod 95 connected thereto to perform a reset movement by virtue of its strong resilience. The reset of the fixed rod 95 further pulls the telescopic airbag 96 to reset synchronously, so that the internal space of the telescopic airbag 96 increases and the pressure decreases. Under the action of the pressure difference, the outside air can smoothly be inhaled into the telescopic airbag 96 through the air suction pipe 97, storing sufficient gas for the subsequent air blowing and cleaning work, ensuring that the air blowing and cleaning assembly can operate continuously and stably, and effectively removing the dust on the metal heat dissipation fins 801.

[0075] The telescopic airbag 96 is installed at the end of the fixed rod 95 away from the rack 94. The air suction pipe 97 is communicated with the telescopic airbag 96. The support plate 98 is fixedly connected to the side wall of the horizontal plate 9. The telescopic airbag 96 is fixedly connected to the support plate 98. The telescopic airbag 96 is made of a high-strength and elastic rubber material, with good flexibility and elastic recovery ability, and can maintain the stability of its shape and performance during repeated telescopic processes, and is not prone to rupture or deformation.

[0076] The air outlet pipe 99 is communicated with the bottom end of the telescopic airbag 96. The gas storage tank 910 is installed on the side wall of the horizontal plate 9. The air outlet pipe 99 communicates with the gas storage tank 910. The air supply pipe 911 is communicated with the gas storage tank 910. The transfer pipe 912 is communicated with the end of the air supply pipe 911 away from the gas storage tank 910. The spray heads 913 are arranged at equal intervals on the transfer pipe 912. There are multiple spray heads 913, and direct-acting electric valves are provided inside all the multiple spray heads 913. After the electromagnetic coil inside the valve is energized, the generated electromagnetic force directly overcomes the spring force and the friction force of the valve core, lifts the valve core, and opens the valve, so that the gas quickly sprays out through the spray heads 913 to clean the metal heat dissipation fins 801; when powered off, the spring force presses the valve core down to close the valve.

[0077] In this embodiment, when the rotating shaft 84 rotates, the second sector gear 91 fixedly connected thereto rotates accordingly. The second sector gear 91 meshes with the rack 94. Since one end of the rack 94 is fixedly connected to the spring 93, and the other end of the spring 93 is fixedly connected to the L-shaped plate 92, when the teeth of the second sector gear 91 do not contact the rack 94, the rack 94 is reset under the action of the spring 93. Driven by the second sector gear 91 and the spring 93, the rack 94 makes a reciprocating linear motion within the L-shaped plate 92, and this motion is transmitted to the telescopic airbag 96 through the fixed rod 95; when the rack 94 moves upward, the fixed rod 95 stretches the telescopic airbag 96 to increase its volume. At this time, the solenoid valve in the air suction pipe 97 is opened, and the outside air is sucked into the telescopic airbag 96 through the air suction pipe 97. When the rack 94 moves downward, the fixed rod 95 compresses the telescopic airbag 96 to reduce its volume, the solenoid valve in the air suction pipe 97 is closed, and the solenoid valve in the air outlet pipe 99 is opened. The air in the telescopic airbag 96 is pressed into the air outlet pipe 99 and enters the gas storage tank 910 for storage; as the gas is continuously pressed in, the air pressure in the gas storage tank 910 increases, and the gas enters the transfer pipe 912 through the air supply pipe 911 and is sprayed out by the nozzles 913 evenly spaced on the transfer pipe 912 to blow away the dust on the metal heat dissipation fins 801, realizing the efficient cleaning of the metal heat dissipation fins 801. At the same time, by blowing air on the metal heat dissipation fins 801, the flow rate of the air can be significantly accelerated, thereby accelerating the heat exchange on the surface of the metal heat dissipation fins 801 and further improving the heat dissipation efficiency.
