Description

Technical Field

[0001] The invention relates to the technical field of hydrogen energy, and in particular to a mobile hydrogen energy power generation system. Background Art

[0002] With the continuous development of human society and the growing demand for electricity, although fixed power stations can provide stable power output, their limitations become apparent in certain specific scenarios, such as remote areas, emergency rescue, and field operations. These scenarios often require power supply equipment to be small in size, light in weight, easy to transport and deploy, so as to quickly respond to various power needs. Therefore, mobile power generation systems came into being and gradually developed into an important part of the power supply field.

[0003] In the prior art, mobile power generation systems usually use diesel generator sets to generate electricity. However, diesel generator sets need to use fuel as energy, which has high energy consumption and high power generation costs. At the same time, diesel generator sets have small capacity and low speed (generally rated speed is 1500r / min), which leads to large voltage waveform distortion and rich third harmonics output by synchronous generators. The power quality is poor and it is difficult to apply to equipment or systems with high power quality requirements. In addition, in order to meet environmental protection requirements, mobile power generation systems based on diesel generator sets need to be equipped with complex and expensive exhaust gas treatment systems, such as catalytic converters, particulate filters, etc., to reduce exhaust emissions, which increases the complexity and cost of the system and affects the reliability and stability of the system. Summary of the invention

[0004] Based on this, it is necessary to provide a mobile hydrogen power generation system to address the problems of high energy consumption, high power generation cost, poor power quality, difficulty in applying to equipment or systems with high power quality requirements, high system complexity, and poor system reliability and stability in the mobile power generation system based on diesel generator sets in the existing technology.

[0006] A mobile hydrogen power generation system comprises a hydrogen engine, wherein the output end of the hydrogen engine is connected to the input end of a generator, and the generator is electrically connected to a battery pack;

[0007] The hydrogen inlet of the hydrogen engine is connected to the hydrogen outlet of the buffer tank through the first hydrogen supply pipe group, and one hydrogen inlet of the buffer tank is connected to the hydrogen gas source through the second hydrogen supply pipe group. The second hydrogen supply pipe group is equipped with a third hydrogen supply pipe group, and the end of the third hydrogen supply pipe group is connected to the gas port of the solid-state hydrogen storage module, and the solid-state hydrogen storage module is filled with solid-state hydrogen storage material. The third hydrogen supply pipe group is equipped with a fourth hydrogen supply pipe group, and the end of the fourth hydrogen supply pipe group is connected to another hydrogen inlet of the buffer tank;

[0008] At the hydrogen absorption temperature, the hydrogen gas source inputs hydrogen into the solid hydrogen storage module through the second hydrogen supply pipe group and the third hydrogen supply pipe group, and the solid hydrogen storage module stores the input hydrogen through the solid hydrogen storage material;

[0009] At the hydrogen release temperature, the solid-state hydrogen storage material inside the solid-state hydrogen storage module releases hydrogen, and the released hydrogen enters the buffer tank through the third hydrogen supply pipe group and the fourth hydrogen supply pipe group. The hydrogen in the buffer tank is input into the hydrogen engine through the first hydrogen supply pipe group. The hydrogen inside the hydrogen engine burns to do work, thereby driving the generator to generate electricity.

[0010] As a further improvement of the above technical solution:

[0011] The structure of the solid-state hydrogen storage module is as follows: it comprises an inner shell, the interior of the inner shell is filled with solid-state hydrogen storage material, the outer shell is matched and installed on the outside of the inner shell, and a gap is provided between the inner wall surface of the outer shell and the outer wall surface of the inner shell, so as to form a heat exchange space between the inner wall surface of the outer shell and the outer wall surface of the inner shell;

[0012] A heat exchanger, an electric heater and a first radiator are respectively installed inside the inner shell, and heat is supplemented by the heat exchanger, the electric heater and the first radiator when the solid hydrogen storage material releases hydrogen.

[0013] The heat exchanger is provided with a first inlet and a first outlet, the first inlet is connected to the exhaust port of the hydrogen engine through a first heat exchange tube group, and the first outlet is matched with a second heat exchange tube group;

[0014] The high-temperature exhaust gas generated by the combustion of hydrogen inside the hydrogen engine enters the heat exchanger through the first heat exchange tube group, thereby exchanging heat with the solid hydrogen storage material inside the inner shell, and is discharged through the second heat exchange tube group after heat exchange.

[0015] The first heat exchange tube group is equipped with an exhaust gas exhaust tube group, and the exhaust gas exhaust tube group is equipped with a bypass valve.

[0016] A second inlet and a second outlet are respectively provided on the wall surface of the outer shell, the second inlet is connected to the coolant outlet of the hydrogen engine through the third heat exchange tube group, and the second outlet is connected to the coolant inlet of the hydrogen engine through the fourth heat exchange tube group, the coolant in the cooling water tank of the hydrogen engine flows into the cooling space through the third heat exchange tube group, and the coolant in the cooling space flows back to the cooling water tank of the hydrogen engine through the fourth heat exchange tube group;

[0017] The first radiator is respectively provided with a heat dissipation inlet and a heat dissipation outlet, both of which are connected to the heat exchange space. The coolant in the heat exchange space flows into the first radiator through the heat dissipation inlet to exchange heat with the solid hydrogen storage material in the inner shell, and the coolant after heat exchange flows back to the heat exchange space through the heat dissipation outlet.

[0021] A one-way valve is installed on the second hydrogen supply pipe group.

[0022] The fourth hydrogen supply pipe group is equipped with a booster pump.

[0023] The beneficial effects of the present invention are as follows:

[0024] The present invention has a compact and reasonable structure and is easy to operate. By arranging a hydrogen engine, a generator, a solid-state hydrogen storage module and a buffer tank, it can output electric energy stably. In the case of emergency power supply, it has a fast response and will not be powered off, so that uninterrupted power supply can be achieved. In addition, the battery pack and the generator can supply power at the same time within a certain period of time to achieve overload power supply and ensure power supply stability. It is suitable for equipment or systems with high requirements on power quality.

[0025] In the present invention, the heat required for the solid-state hydrogen storage module to release hydrogen mainly comes from the exhaust of the hydrogen engine and the heat dissipation of the cooling system, which effectively improves the energy utilization efficiency of the system; when the solid-state hydrogen storage module absorbs hydrogen, the heat exchange module configured by the hydrogen engine is used to dissipate heat, which effectively reduces the complexity of the system.

[0031] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0032] The structure and function of the present invention are as follows:

[0033] like Figure 1-Figure 2As shown, a mobile hydrogen power generation system includes a hydrogen engine 1, the output end of the hydrogen engine 1 is connected to the input end of the generator 2, and the generator 2 is electrically connected to the battery pack 6; the hydrogen inlet of the hydrogen engine 1 is connected to the hydrogen outlet of the buffer tank 5 through the first hydrogen supply pipe group 11, and a hydrogen inlet of the buffer tank 5 is connected to the hydrogen gas source through the second hydrogen supply pipe group 12, and the second hydrogen supply pipe group 12 is equipped with a third hydrogen supply pipe group 13, and the end of the third hydrogen supply pipe group 13 is connected to the gas port of the solid-state hydrogen storage module 3, and the solid-state hydrogen storage module 3 is filled with solid-state hydrogen storage material 303, and the third hydrogen supply pipe group 13 is equipped with a fourth hydrogen supply pipe group 14, and the fourth hydrogen supply pipe group 15 is equipped with a fourth hydrogen supply pipe group 16. The end of the four hydrogen supply tube groups 14 is connected to another hydrogen inlet of the buffer tank 5; at the hydrogen absorption temperature, the hydrogen gas source inputs hydrogen into the solid hydrogen storage module 3 through the second hydrogen supply tube group 12 and the third hydrogen supply tube group 13, and the solid hydrogen storage module 3 stores the input hydrogen through the solid hydrogen storage material 303; at the hydrogen release temperature, the solid hydrogen storage material 303 inside the solid hydrogen storage module 3 releases hydrogen, and the released hydrogen enters the buffer tank 5 through the third hydrogen supply tube group 13 and the fourth hydrogen supply tube group 14, and the hydrogen in the buffer tank 5 is input into the hydrogen engine 1 through the first hydrogen supply tube group 11, and the hydrogen inside the hydrogen engine 1 burns to do work, thereby driving the generator 2 to generate electricity. By setting the solid hydrogen storage module 3, hydrogen can be stably supplied to the hydrogen engine 1, so that the generator 2 can stably output electrical energy, which is suitable for equipment or systems with high requirements for power quality, and the system has good safety and stability, low overall energy consumption of the system, and low power generation cost.

[0034] The mobile hydrogen power generation system of the present invention comprises a hydrogen engine 1, a generator 2, a solid hydrogen storage module 3, a buffer tank 5, a battery pack 6, and a heat exchange module 8; wherein:

[0035] The hydrogen engine 1 burns and works, and can convert the internal energy generated by the combustion of hydrogen into mechanical energy. Its output shaft is connected to the input end of the generator 2, and the mechanical energy generated by the movement of the output shaft is converted into electrical energy through the generator 2.

[0036] In the present invention, the power output end of the generator 2 is electrically connected to the battery pack 6, and a part of the power generated by the generator 2 is stored through the battery pack 6. The battery pack 6 is provided with a battery charging port for charging it with an external power source; the power output end of the generator 2 is configured with a power output circuit, which can directly supply power to the outside; the battery pack 6 also provides power input to the power output circuit of the generator 2 through the inverter 7, and the battery pack 6 and the generator 2 can simultaneously supply power to the outside through the power output circuit within a certain period of time to achieve overload power supply, thereby further improving the power supply stability of the system; in addition, when the hydrogen engine 1 is started (about 10s-20s), the power output circuit is provided with power input through the battery pack 6, which can ensure that the system achieves uninterrupted power supply.

[0037] In addition, the battery pack 6 supplies power to the hydrogen engine 1, the heat exchange module 8, and the electric heater 309 respectively, so that when the exhaust heat and cooling capacity of the hydrogen engine 1 are insufficient to support its rapid release of hydrogen, auxiliary heating can be performed through the battery pack 6; the system circuits are equipped with electric switches to ensure the safety of the system power supply.

[0038] like Figure 2 As shown, the structure of the solid-state hydrogen storage module 3 is as follows: it includes an inner shell 301, the interior of the inner shell 301 is filled with a solid-state hydrogen storage material 303, the outer shell 302 is installed on the outside of the inner shell 301, and a gap is provided between the inner wall surface of the outer shell 302 and the outer wall surface of the inner shell 301, so as to form a heat exchange space 304 between the inner wall surface of the outer shell 302 and the outer wall surface of the inner shell 301; a heat exchanger 310, an electric heater 309 and a first radiator 311 are respectively installed inside the inner shell 301, and heat is supplemented by the heat exchanger 310, the electric heater 309 and the first radiator 311 when the solid-state hydrogen storage material 303 releases hydrogen. The solid-state hydrogen storage module 3 can absorb or release hydrogen based on the solid-state hydrogen storage material 303, and the solid-state hydrogen storage material 303 preferably uses magnesium hydride material; by setting a heat exchanger 310, an electric heater 309 and a first radiator 311, it is possible to ensure that the temperature inside the inner shell 301 is stable at the hydrogen absorption temperature or hydrogen release temperature of the solid-state hydrogen storage material 303.

[0039] The heat exchanger 310 is respectively provided with a first inlet 305 and a first outlet 306. The first inlet 305 is connected to the exhaust port of the hydrogen engine 1 through the first heat exchange tube group 16, and the first outlet 306 is installed with a second heat exchange tube group 17. The high-temperature exhaust gas generated by the combustion of hydrogen inside the hydrogen engine 1 enters the heat exchanger 310 through the first heat exchange tube group 16, thereby exchanging heat with the solid hydrogen storage material 303 inside the inner shell 301, and is discharged through the second heat exchange tube group 17 after heat exchange. The first heat exchange tube group 16 is installed with an exhaust gas exhaust pipe group 15, and the exhaust gas exhaust pipe group 15 is installed with a bypass valve 9.

[0040] By providing the first heat exchange tube group 16, the exhaust gas discharge tube group 15 and the bypass valve 9, the exhaust energy of the hydrogen engine 1 can be fully utilized; when the hydrogen engine 1 is cold-started, since the exhaust gas temperature generated by the hydrogen engine 1 is relatively low at this time and cannot reach the temperature for heating the solid-state hydrogen storage module 3, the bypass valve 9 is opened so that the low-temperature exhaust gas generated by the hydrogen engine 1 is discharged into the atmosphere through the first heat exchange tube group 16 and the exhaust gas discharge tube group 15 in sequence; when the hydrogen engine 1 runs stably, the bypass valve 9 is closed, and the high-temperature exhaust gas discharged by the hydrogen engine 1 enters the interior of the heat exchanger 310 through the first heat exchange tube group 16, thereby heating the solid-state hydrogen storage material 303 inside the inner shell 301 to reach the hydrogen release temperature, and the solid-state hydrogen storage material 303 stably releases hydrogen, thereby stably supplying hydrogen to the hydrogen engine 1.

[0041] A second inlet 307 and a second outlet 308 are respectively provided on the wall surface of the outer shell 302. The second inlet 307 is connected to the coolant outlet of the hydrogen engine 1 through the third heat exchange tube group 18, and the second outlet 308 is connected to the coolant inlet of the hydrogen engine 1 through the fourth heat exchange tube group 19. The coolant in the cooling water tank of the hydrogen engine 1 flows into the heat exchange space 304 through the third heat exchange tube group 18, and the coolant in the heat exchange space 304 flows back to the cooling water tank of the hydrogen engine 1 through the fourth heat exchange tube group 19; a heat dissipation inlet 312 and a heat dissipation outlet 313 are respectively provided on the first radiator 311, and the heat dissipation inlet 312 and the heat dissipation outlet 313 are both connected to the heat exchange space 304. The coolant in the heat exchange space 304 flows into the first radiator 311 through the heat dissipation inlet 312 to exchange heat with the solid hydrogen storage material 303 in the inner shell 301, and the coolant after heat exchange flows back to the heat exchange space 304 through the heat dissipation outlet 313. The third heat exchange tube group 18 is equipped with a first branch pipe 20, the end of which is connected to the liquid inlet of the heat exchange module 8. The fourth heat exchange tube group 19 is equipped with a second branch pipe 21, the end of which is connected to the liquid outlet of the heat exchange module 8. The heat exchange module 8 includes a second radiator 801, and a fan 802 is arranged beside the second radiator 801. The fan 802 fans air, thereby dissipating the coolant inside the second radiator 801.

[0042] In the present invention, the heat exchange module 8 is used to cool the coolant in the cooling water tank of the hydrogen engine 1. The heat exchange module 8 includes a second radiator 801 and a fan 802. The heat dissipation and cooling of the second radiator 801 is completed by the fan 802. The fan 802 is driven by a drive motor. The drive motor is powered by the battery pack 6. The drive motor controls the rotation speed of the fan 802 according to the cooling demand of the hydrogen engine 1, thereby adjusting the heat exchange amount. Compared with directly mechanically connecting the fan 802 to the hydrogen engine 1, the heat exchange method in which the rotation speed of the fan 802 is fixed can reduce power consumption and energy consumption.

[0043] In the present invention, when the hydrogen engine 1 is in a stable working state, most of the coolant (i.e., cooling water) in the cooling water tank of the hydrogen engine 1 flows into the heat exchange space 304 through the third heat exchange tube group 18 to keep the inner shell 301 warm. At the same time, the coolant in the heat exchange space 304 flows into the first radiator 311 through the heat dissipation inlet 312 to heat the solid hydrogen storage material 303 inside the inner shell 301 to reach the hydrogen release temperature. The coolant in the heat exchange space 304 flows into the first radiator 311 through the heat dissipation inlet 312 to heat the solid hydrogen storage material 303 inside the inner shell 301 to reach the hydrogen release temperature. The cooling liquid flows back to the cooling water tank of the hydrogen engine 1 through the third heat exchange tube group 19; a small portion of the cooling liquid in the cooling water tank of the hydrogen engine 1 flows into the second radiator 801 through the third heat exchange tube group 18 and the first branch pipe 20 in sequence, and the cooling liquid in the second radiator 801 flows into the fourth heat exchange tube group 19 through the second branch pipe 21 to merge. When the temperature of the merged cooling liquid cannot meet the cooling requirement of the hydrogen engine 1, the control driving motor is started to drive the fan 802 to accelerate the heat dissipation so as to reduce the temperature of the cooling liquid in the second radiator 801.

[0044] When the system is in the hydrogenation state, that is, when the solid hydrogen storage material 303 absorbs hydrogen, the coolant circulates between the heat exchange space 304 and the second radiator 801 without passing through the hydrogen engine 1. The specific process is as follows:

[0045] The coolant in the heat exchange space 304 flows into the second radiator 801 through the fourth heat exchange tube group 19 and the second branch pipe 21 in sequence, and after being cooled by the fan 802, it flows back to the heat exchange space 304 through the first branch pipe 20 and the third heat exchange tube group 18, thereby taking away the heat released by the solid hydrogen storage material 303 absorbing hydrogen, so that the temperature in the inner shell 301 is stabilized at the hydrogen absorption temperature.

[0046] A one-way valve 10 is installed on the second hydrogen supply pipe group 12. The one-way valve 10 is used to prevent the hydrogen in the second hydrogen supply pipe group 12 from flowing back, thereby preventing the hydrogen from flowing out of the hydrogenation port.

[0047] A booster pump 4 is mounted on the fourth hydrogen supply pipe group 14 . The booster pump 4 is used to increase the pressure of hydrogen in the fourth hydrogen supply pipe group 14 to meet the use of the hydrogen engine 1 .

[0048] At least two hydrogen inlets are provided on the buffer tank 5, one of which is used to be connected to a hydrogen gas source through a second hydrogen supply pipe group 12, and the other hydrogen inlet is used to be connected to a gas port of the solid-state hydrogen storage module 3 through a fourth hydrogen supply pipe group 14 and a third hydrogen supply pipe group 13; a small amount of hydrogen needs to be pre-filled inside the buffer tank 5 for starting the hydrogen engine 1; in addition, by providing the buffer tank 5, the hydrogen released by the solid-state hydrogen storage module 3 can be buffered to prevent the hydrogen pressure fluctuation caused by the hydrogen release of the solid-state hydrogen storage module 3 from affecting the performance of the hydrogen engine 1.

[0049] The working process of the present invention is as follows:

[0050] When charging hydrogen to the mobile hydrogen power generation system, the hydrogen source first charges part of the hydrogen into the buffer tank 5 through the second hydrogen supply pipe group 12, and then the hydrogen source charges hydrogen into the solid hydrogen storage module 3 through the second hydrogen supply pipe group 12 and the third hydrogen supply pipe group 13 in sequence;

[0051] At the same time, the battery pack 6 supplies power to the electric heater 309, so that the temperature inside the inner shell 301 rises to the hydrogen absorption temperature of the solid hydrogen storage material 303, and the solid hydrogen storage material 303 begins to absorb hydrogen and release heat;

[0052] The electric heater 309 is powered off, and the coolant in the heat exchange space 304 flows into the second radiator 801 through the third heat exchange tube group 18 and the first branch pipe 20. After being cooled by the fan 802, it flows back to the heat exchange space 304 through the fourth heat exchange tube group 19 and the second branch pipe 21, thereby ensuring that the temperature inside the inner shell 301 is stable within the hydrogen absorption temperature range.

[0053] When the mobile hydrogen power generation system stably supplies power to the outside, hydrogen is first supplied to the hydrogen engine 1 through the buffer tank 5, thereby starting the hydrogen engine 1;

[0054] At the same time, the battery pack 6 supplies power to the electric heater 309, so that the temperature inside the inner shell 301 rises to the hydrogen release temperature of the solid hydrogen storage material 303, and the solid hydrogen storage material 303 begins to release hydrogen and absorb heat;

[0055] After the hydrogen engine 1 is started, it drives the generator 2 to generate electricity stably, thereby supplying power to the outside through the power output circuit, and the excess power is input into the battery pack 6 for storage;

[0056] The high-temperature exhaust gas generated by the combustion of hydrogen inside the hydrogen engine 1 enters the heat exchanger 310 through the first heat exchange tube group 16 in sequence, thereby replenishing the heat absorbed by the solid hydrogen storage material 303 during hydrogen release, and ensuring that the temperature inside the inner shell 301 is stable at the hydrogen release temperature; at the same time, the coolant in the cooling water tank of the hydrogen engine 1 flows into the heat exchange space 304 through the third heat exchange tube group 18, and flows into the first radiator 311 through the heat dissipation inlet 312, and the coolant in the first radiator 311 exchanges heat with the solid hydrogen storage material 303 inside the inner shell 301, thereby replenishing the heat absorbed by the solid hydrogen storage material 303 during hydrogen release, and ensuring that the temperature inside the inner shell 301 is stable at the hydrogen release temperature;

[0057] The solid hydrogen storage material 303 stably releases hydrogen, and the released hydrogen enters the buffer tank 5 through the third hydrogen supply pipe group 13 and the fourth hydrogen supply pipe group 14 in sequence, and is then input into the hydrogen engine 1 through the first hydrogen supply pipe group 11, ensuring that the hydrogen engine 1 stably drives the generator 2 to generate electricity.

[0058] The above description is an explanation of the present invention, not a limitation of the present invention. The scope of the present invention is defined in the claims. Any form of modification may be made within the scope of protection of the present invention.
