[0023] Embodiment 1:

[0024] This embodiment discloses a hydrogen internal combustion engine power generation system, such as Figure 1 As shown, the hydrogen internal combustion engine power generation system may include but is not limited to a hydrogen energy storage system, a power generation system, an electric energy management system, a first container 1 and a second container 2, wherein the hydrogen energy storage system is arranged in the first container 1, and the power generation system and the electric energy management system are arranged in the second container 2; the power generation system includes a hydrogen internal combustion engine and a generator 3, wherein the hydrogen internal combustion engine includes an engine cylinder 4, wherein the engine cylinder 4 is connected to the hydrogen energy storage system through a hydrogen delivery pipeline, wherein the engine cylinder 4 is used to drive the hydrogen from the hydrogen energy storage system to undergo an electrochemical reaction with the oxygen from the air delivery pipeline and convert it into mechanical energy, wherein the generator 3 is transmission-connected to the engine cylinder 4, wherein the generator 3 is used to convert the mechanical energy generated by the engine cylinder 4 into electric energy, and transmit the electric energy to the electric energy management system.

[0025] Specifically, in this embodiment, hydrogen is transported from the hydrogen energy storage system to the engine cylinder 4 of the hydrogen internal combustion engine through the hydrogen transportation pipeline, and is mixed with the air transported to the combustion chamber of the engine cylinder 4 through the air transportation pipeline, and a combustion reaction occurs to convert the chemical energy of the combustion of hydrogen and oxygen into mechanical energy. Then, the crankshaft connecting rod structure of the engine cylinder 4 drives the generator 3 to move, so that the generator 3 converts the mechanical energy into electrical energy. Finally, the electrical energy generated by the generator 3 is transported to the power management system, so as to supply power to the user-side electrical equipment through the power grid 38, and the excess electrical energy can be stored in the energy storage battery 39 of the power management system.

[0026] The structure of this embodiment is compact and convenient for transportation and installation. Specifically, the hydrogen internal combustion engine generator set in this embodiment adopts a containerized modular design. By setting up a hydrogen energy storage system, a power generation system, and a power management system that are connected in sequence, the function of converting hydrogen energy into electrical energy is realized. At the same time, the hydrogen energy storage system is arranged in the first container 1, and the power generation system and the power management system are arranged in the second container 2, which is convenient for the transportation and installation of the hydrogen internal combustion engine generator set, and is especially suitable for occasions that require quick response such as temporary projects and emergency backup power supplies. Furthermore, it is beneficial to expand the application scenarios of hydrogen energy in the power generation field, improve the reliability and emergency response ability of green energy supply, and has the value of popularization and application.

[0027] In this embodiment, the hydrogen internal combustion engine power generation system further includes a waste heat recovery and utilization system and a third container 5. The waste heat recovery and utilization system is arranged in the third container 5. The waste heat recovery and utilization system includes a chilled and hot water unit 6 and a water tank 7. The chilled and hot water unit 6 includes a fresh water heat exchange channel, a gas heat exchange channel, and a coolant heat exchange channel. The gas heat exchange channel and the coolant heat exchange channel are both heat exchange-connected to the fresh water heat exchange channel. The fresh water heat exchange channel is communicated with the water tank 7. The water tank 7 is used to supply water to the user's pipe network 8. The gas heat exchange channel is communicated with the exhaust pipe of the engine cylinder 4. The fresh water heat exchange channel is communicated with the coolant circulation pipeline of the hydrogen internal combustion engine.

[0028] In this embodiment, by setting up a waste heat recovery and utilization system, in addition to providing electrical energy, chilled and hot water can be further provided for users, realizing diversified energy output, and meeting the energy application requirements in more scenarios.

[0029] It should be noted that in this embodiment, the chilled and hot water unit 6 is used to transfer the waste heat of the exhaust gas in the exhaust pipe of the engine cylinder 4 and the waste heat of the circulating water in the coolant circulation pipeline of the hydrogen internal combustion engine to the water tank 7, so as to realize the reuse of the waste heat of the exhaust gas in the exhaust pipe of the engine cylinder 4 and the waste heat of the circulating water in the coolant circulation pipeline of the hydrogen internal combustion engine.

[0030] It should be noted that in this embodiment, the three containers, namely the first container 1, the second container 2, and the third container 5, exist independently of each other. They can be connected through pipelines, cable lines, etc. to form a complete combined cooling, heating, and power generation system. In addition, according to different application scenarios, the corresponding containers can be increased or decreased, which is not limited here.

[0031] In this embodiment, the power generation system further includes a secondary water tank 9, a radiator 10, and a first three-way valve 11. The hydrogen internal combustion engine further includes an engine water pump 12, an engine water jacket 13, a water temperature sensor 14, and a thermostat 15. The outlet of the secondary water tank 9 and the first water outlet of the first three-way valve 11 are both connected to the water inlet of the radiator 10. The water outlet of the radiator 10 is sequentially connected to the water inlet of the thermostat 15 through the engine water pump 12 and the engine water jacket 13. The water temperature sensor 14 is used to measure the water temperature at the water outlet of the engine water jacket 13. The first water outlet of the thermostat 15 is connected to the water inlet of the engine water pump 12. The second water outlet of the thermostat 15 is connected to the water inlet of the first three-way valve 11. The second water outlet of the first three-way valve 11 is connected to the water inlet of the chilled and hot water unit 6 through the coolant heat exchange channel.

[0032] In this embodiment, the secondary water tank 9 is used to hold the coolant. The radiator 10 can be, but is not limited to, a fin-tube radiator 10 and a plate-fin radiator 10. It improves the heat dissipation efficiency by increasing the heat dissipation area and optimizing the air flow distribution to ensure the thermal management requirements of the hydrogen internal combustion engine under different working conditions.

[0033] In this embodiment, in the hydrogen internal combustion engine, the engine water pump 12 is used to pump the coolant into the engine water jacket 13. The engine water jacket 13 is arranged around the cylinder block and cylinder head of the engine cylinder 4 to absorb the heat generated when the engine cylinder 4 works. The thermostat 15 controls the flow direction of the coolant according to the temperature, determining whether it enters the small cycle (internal cycle) or the large cycle (through the radiator 10).

[0034] Specifically, when the coolant of the hydrogen internal combustion engine circulates inside the engine cylinder 4 (mainly in the engine water jacket 13 of the cylinder block and cylinder head), it constitutes a small coolant cycle, which is mainly used for the rapid warm-up stage after the hydrogen internal combustion engine starts to help the engine reach the normal working temperature as soon as possible. In this embodiment, after the hydrogen internal combustion engine starts, the coolant flows out of the engine water pump 12 and directly enters the engine water jacket 13 to absorb the heat generated when the engine cylinder 4 works, and then flows back to the engine water pump 12 to form a closed circulation loop.

[0035] When the coolant of the hydrogen internal combustion engine circulates between the interior of the engine and the external radiator 10, a large coolant circulation is formed, which can be used for heat dissipation during high-temperature operation of the engine to prevent the engine from overheating. Specifically, during implementation, when the temperature of the engine cylinder 4 rises to a certain value (manifested as the water temperature detected by the water temperature sensor 14 being greater than a certain value), the thermostat 15 opens, and the coolant flows out from the engine water jacket 13, is cooled by passing through the radiator 10, and then returns to the engine water pump 12, forming a larger circulation loop. In this embodiment, due to the provision of the first three-way valve 11, during the large coolant circulation, the coolant that has absorbed the heat of the engine cylinder 4 can flow into the coolant heat exchange channel through the first three-way valve 11, and thus the heat of the engine cylinder 4 can be transferred to the fresh water heat exchange channel.

[0036] In this embodiment, the power generation system further includes a second three-way valve 16 and a muffler 17. The first intake port of the second three-way valve 16 is communicatively connected to the outlet of the exhaust pipe of the engine cylinder 4, the first outlet port of the second three-way valve 16 is communicatively connected to the muffler 17, and the second outlet port of the second three-way valve 16 is communicatively connected to the muffler 17 through the gas heat exchange channel. It should be noted that in this embodiment, the second three-way valve 16 is used to transfer the waste heat of the exhaust gas in the exhaust pipe of the engine cylinder 4 to the fresh water heat exchange channel; the muffler 17 is used to reduce the exhaust noise of the engine cylinder 4.

[0037] In this embodiment, the power generation system further includes an air pre-filter 18, an air filter 19, a supercharger, an intercooler 20, and an intake throttle valve 21 arranged in sequence along the intake direction of the air delivery pipeline. In addition, in this embodiment, an air detection sensor 40 is further provided at the outlet of the air filter 19, which can be but is not limited to an air pressure sensor or an air temperature sensor, so as to monitor the air pressure or air temperature in the air delivery pipeline.

[0038] Specifically, in this embodiment, the air pre-filter 18 is used to preliminarily filter larger particulate matters and impurities in the air entering the power generation system, so as to protect subsequent equipment from damage by large particulate pollutants and improve the reliability of the entire power generation system; the air filter 19 is used to further filter minute dust, particles and other impurities in the air to provide high-quality air for the combustion process, ensure the cleanliness of the air entering the power generation system, and avoid abrasion or blockage of precision components; the supercharger increases the intake pressure by compressing the air, thereby increasing the air density per unit volume, which helps the oxygen in the air to better mix with hydrogen and optimize the combustion performance; the intercooler 20 is used to cool the air whose temperature has risen after being compressed by the supercharger to increase the air density and further improve the combustion efficiency; the intake throttle valve 21 is used to control the air flow rate entering the power generation system.

[0039] In this embodiment, the supercharger includes a compressor 22 and a turbine 23 that are drivingly connected. The compressor 22 is arranged between the air filter 19 and the intercooler 20, and the turbine 23 is arranged on the exhaust pipe of the engine cylinder 4 of the hydrogen internal combustion engine; the power generation system further includes an EGR (Exhaust Gas Recirculation) valve 24. The intake port of the EGR valve 24 is communicated with the exhaust pipe of the engine cylinder 4, and the outlet port of the EGR valve 24 is communicated with the air delivery pipeline.

[0040] In this embodiment, the turbine 23 and the compressor 22 are drivingly connected through a common shaft. During the implementation process, the exhaust gas of the engine cylinder 4 is discharged into the turbine 23 to drive the turbine 23 to rotate. The turbine 23 can further drive the compressor 22 to rotate through the common shaft, so that the compressor 22 compresses the air delivered from the air filter 19 and then sends it into the engine cylinder 4 of the hydrogen internal combustion engine, thereby improving the combustion efficiency of hydrogen and oxygen in the air. This setting not only improves the performance of the hydrogen internal combustion engine, but also effectively reduces energy waste and realizes energy recovery from the exhaust gas of the engine cylinder 4 in the hydrogen internal combustion engine.

[0041] In addition, in this embodiment, the outlet port of the EGR valve 24 is communicated with the outlet port of the intake throttle valve 21 and the intake port of the engine cylinder 4; in this embodiment, the EGR valve 24 is used to reintroduce part of the exhaust gas in the exhaust pipe of the engine cylinder 4 into the engine cylinder 4 of the hydrogen internal combustion engine to reduce the combustion temperature and nitrogen oxide emissions.

[0042] In this embodiment, the hydrogen internal combustion engine power generation system further includes a hydrogen safety system, such as Figure 2As shown, the hydrogen safety system includes a fire extinguishing controller 25, a first hydrogen concentration sensor 26, a first temperature sensor 27, a first fire detector 28, and a first fire extinguishing nozzle 29 that are electrically connected to the fire extinguishing controller 25.

[0043] In this embodiment, the hydrogen safety system further includes a second hydrogen concentration sensor 30, a second temperature sensor 31, a second fire detector 32, and a second fire extinguishing nozzle 33 that are electrically connected to the fire extinguishing controller 25.

[0045] Specifically, in this embodiment, both the first fire detector 28 and the second fire detector 32 may include a spot-type heat fire detector and a spot-type photoelectric smoke fire detector. Among them, the spot-type heat fire detector is used to monitor changes in the ambient temperature so as to issue a fire alarm when the temperature exceeds a set threshold, and the spot-type photoelectric smoke fire detector is used to detect the smoke concentration so as to trigger a fire alarm when the smoke reaches a certain level.

In this embodiment, the protection modes of the hydrogen safety system include a primary protection mode and an advanced protection mode.

[0047] Among them, the primary protection mode of the hydrogen safety system is as follows: the hydrogen concentration is detected by the first hydrogen concentration sensor 26 and the second hydrogen concentration sensor 30, the ambient temperature is detected by the first temperature sensor 27 and the second temperature sensor 31, and the hydrogen concentration and temperature are transmitted to the main control module through the fire extinguishing controller 25; subsequently, the main control module processes the input signal and compares it with the pre-calibrated value. When the converted value of the signal input by any one sensor exceeds the range set by the calibration value, the main control module sends a shutdown command to the hydrogen internal combustion engine in the power generation system, the hydrogen internal combustion engine shuts down, and at the same time the main control module sends a command to the safety valve 37 of the hydrogen energy storage system to require the cut-off of hydrogen supply.

[0048] The advanced protection mode of the hydrogen safety system is as follows: when any one of the first fire detector 28 and the second fire detector 32 detects a fire signal, the automatic fire extinguishing program is triggered, and then the fire extinguishing gas is transported from the gas fire extinguishing cylinder to the first fire nozzle 29 or the second fire nozzle 33, and the first fire nozzle 29 or the second fire nozzle 33 sprays the fire extinguishing gas into the container with the fire signal respectively; at the same time, when the first temperature sensor 27 and the second temperature sensor 31 detect that the temperature is too high, the primary protection mode is triggered to cut off the hydrogen supply.

It should be noted that in this embodiment, the generator 3 is electrically connected to the power grid 38 and the storage battery 39, and can realize the utilization and storage of the electric energy generated by the power generation system.

[0052] Specifically, in this embodiment, the power management system further includes a voltage sensor, a current sensor, and an alarm signal lamp electrically connected to the main control module.
