[0030] See Figure 1 and Figure 2 The present invention provides a hydrogen direct-fired supercritical carbon dioxide energy storage power station, comprising a main engine area 1, a first heat exchange area 2, a second heat exchange area 3, a heat storage area 4 and a carbon dioxide air bag 5. The main engine area 1 includes a compression mechanism 11 and a turbine mechanism 12; the first heat exchange area 2 and the second heat exchange area 3 are respectively arranged on both sides of the main engine area 1, the first heat exchange area 2 includes a water cooler 21, a radiator 22 and a first condenser 23, and the second heat exchange area 3 includes a regenerator 31 and a second condenser 32; the heat storage area 4 is arranged on one side of the main engine area 1; and the carbon dioxide air bag 5 is connected to the main engine area 1.

[0031] In this embodiment, the main engine area 1 is provided with a partition wall (not shown in the figure), the first heat exchange area 2 and the second heat exchange area 3 are both arranged on the outside of the partition wall, and the first heat exchange area 2 and the second heat exchange area 3 are respectively arranged on both sides of the width direction of the main engine area 1, a plurality of water coolers 21 are provided, and the plurality of water coolers 21 are arranged at equal intervals along the length direction of the main engine area 1, the radiator 22 and the first condenser 23 are arranged on the same side of the water cooler 21, and a plurality of heat regenerators 31 are provided, and the plurality of heat regenerators 31 are arranged at intervals.

[0032] In this way, the carbon dioxide air bag 5 can store a large amount of carbon dioxide, making the location of the hydrogen direct-fired supercritical carbon dioxide energy storage power station more flexible, reducing dependence on the environment, improving the flexibility of site selection, reducing environmental limitations, and facilitating the transportation of carbon dioxide to the condenser, reducing the length of large-diameter low-pressure pipelines, and reducing power loss; the compression mechanism 11 and the turbine mechanism 12 are arranged inside the main engine area 1, and other structures are arranged outside the main engine area 1, which can save the floor space of the main engine area 1. By dividing the areas according to function, the problems of process medium path return, equipment cross-interference, etc. are reduced, the space utilization rate is improved, the functional areas are arranged compactly, space waste is reduced, and the length of connecting cables and process pipelines is reduced, the project cost and construction difficulty are reduced, and costs are saved.

[0033] It is understandable that the number and location of the water coolers 21 and the regenerators 31 can be adjusted according to actual needs, and no further details are given here.

[0034] See Figure 2 In some embodiments, the compression mechanism 11 includes a first compressor 111 , a second compressor 112 and a compressor lubricating oil device 113 , and the first compressor 111 and the second compressor 112 are respectively arranged on both sides of the compressor lubricating oil device 113 .

[0035] In this embodiment, the first compressor 111 is a low-pressure compressor, the second compressor 112 is a high-pressure compressor, and the compressor lubricating oil device 113 is connected to both the first compressor 111 and the second compressor 112 .

[0036] In this way, the space of the main engine area 1 can be fully utilized, the distance between the compressor lubricating oil device 113 and the first compressor 111 and the second compressor 112 can be shortened, the length of the lubricating oil pipeline can be reduced, the energy consumption of the lubricating oil pump can be reduced, and the power consumption rate of the hydrogen direct-fired supercritical carbon dioxide energy storage power station can be reduced. The floor area of ​​the main engine area 1 can be reduced, the cost of pipeline materials and laying costs can be reduced, and the internal structure of the main engine area 1 can be made more compact.

[0037] It can be understood that multiple first compressors 111 and multiple second compressors 112 can be set, and multiple first compressors 111 and multiple second compressors 112 can be arranged in sequence from small to large according to working pressure. The number of first compressors 111 and second compressors 112 can be adjusted according to actual needs, which will not be elaborated here.

[0038] See Figure 2 In some embodiments, the turbine mechanism 12 includes a turbine generator set 121, a turbine control oil station 122, a turbine top shaft oil station 123, and a turbine lubricating oil station 124, and the main engine area 1 also includes a carbon dioxide pressurizing pump 15 and an oxygen pressurizing device 16.

[0039] In this embodiment, the turbine control oil station 122, the turbine top shaft oil station 123 and the turbine lubricating oil station 124 are all arranged on the side of the turbine generator set 121 facing the compressed lubricating oil device, and the carbon dioxide pressurizing pump 15 and the oxygen pressurizing device 16 are both spaced apart from the turbine generator set 121.

[0040] In this way, the compression mechanism 11 and the turbine mechanism 12 are arranged compactly, and the turbine control oil station 122, the turbine top shaft oil station 123 and the turbine lubricating oil station 124 are all arranged close to the compression lubricating oil device, which can facilitate the first compressor 111, the second compressor 112 and the turbine generator set 121 to share a set of lubricating oil treatment and oil supply and return devices, reduce the length of cables and process pipelines, and save project costs.

[0041] It is understandable that there can be multiple turbine generator sets 121, and the multiple turbine generator sets 121 are arranged at intervals. The number and setting positions of the turbine generator sets 121 can be flexibly adjusted, and no further enumeration is given here.

[0042] See Figure 2 In some embodiments, the main engine area 1 further includes a maintenance area 13 , and the compression mechanism 11 and the turbine mechanism 12 are respectively arranged on both sides of the maintenance area 13 .

[0043] In this embodiment, the length direction of the maintenance area 13 is parallel to the length direction of the main engine area 1, and along the width direction of the main engine area 1, the compression mechanism 11, the maintenance area 13, and the turbine mechanism 12 are arranged at intervals.

[0044] In this way, the compression mechanism 11 and the turbine mechanism 12 are arranged on both sides of the maintenance area 13, which can facilitate the staff to repair the compression mechanism 11 and the turbine mechanism 12 as needed, reduce the moving distance of the staff, improve the space utilization rate of the main engine area 1, avoid the scattered arrangement of the maintenance equipment due to the long distance between the compression mechanism 11 and the turbine mechanism 12, save the number of maintenance equipment arranged, and achieve a reasonable layout.

[0045] See Figure 2In some embodiments, the first heat exchange area 2 is disposed on the side of the compression mechanism 11 facing away from the maintenance area 13, and the second heat exchange area 3 is disposed on the side of the turbine mechanism 12 facing away from the maintenance area 13. In this embodiment, along the width direction of the main engine area 1, the first heat exchange area 2, the compression mechanism 11, the maintenance area 13, the turbine area, and the second heat exchange area 3 are spaced apart.

[0046] In this way, according to the required heat exchange type, the first heat exchange area 2 and the second heat exchange area 3 can be placed close to the compression mechanism 11 and the turbine mechanism 12 respectively, reducing the cross-arrangement, making the structure of the hydrogen direct-fired supercritical carbon dioxide energy storage power station more compact and reducing the footprint; the turbine mechanism 12 is set close to the second heat exchange, which can shorten the exhaust pipe length of the turbine generator set 121 and reduce the exhaust pressure loss and exhaust back pressure.

[0047] It is understandable that the locations of the first heat exchange zone 2 and the second heat exchange zone 3 can be adjusted according to the locations of the compression mechanism 11 and the turbine mechanism 12, and no further details are given here.

[0048] See Figure 2 In some embodiments, the main engine area 1 further includes a passage 14, which is located in correspondence with the maintenance area 13. The compression mechanism 11 and the turbine mechanism 12 are respectively disposed on either side of the passage 14. In this embodiment, the width of the passage 14 is greater than the width of the maintenance area 13, and the passage 14 is disposed at one end of the maintenance area 13.

[0049] In this way, it is convenient for vehicles transporting maintenance parts to enter and exit, avoids occupying extra space in the main engine area 1, improves space utilization, shortens the transportation path of maintenance parts, and improves maintenance efficiency and transportation efficiency.

[0050] It can be understood that there can be multiple channels 14. In this embodiment, only one channel 14 is provided in order to reduce the space occupied by the host area 1 and to allow more space inside the host area 1 to accommodate other structures. The number and location of the channels 14 can be adjusted according to actual needs and will not be listed in detail here; the host area 1 can also be provided with a lifting crane to improve maintenance efficiency.

[0051] See Figure 1 and Figure 3 In some embodiments, the hydrogen direct-fired supercritical carbon dioxide energy storage power station further includes a booster station area 6 , and the booster station area 6 and the heat storage area 4 are arranged on the same side of the main engine area 1 .

[0052] In this embodiment, the hydrogen direct-fired supercritical carbon dioxide energy storage power station also includes an injection equipment area 8 and a liquid carbon dioxide storage tank area 9. The injection equipment area 8 and the liquid carbon dioxide storage tank area 9 are arranged on the other side of the main engine area 1. The injection equipment area 8 includes a carbon dioxide filling pump, a carbon dioxide gasifier and a carbon dioxide buffer tank. The liquid carbon dioxide storage tank area 9 includes a tank body (not shown in the figure), and the tank body is a high-pressure liquid carbon dioxide storage tank.

[0053] In this way, the booster station area 6 and the heat storage area 4 are arranged on the same side of the main unit area 1, which can shorten the cable length, reduce line loss and construction costs, and reduce the connection costs between various devices; the filling equipment area 8 and the liquid carbon dioxide storage tank area 9 are arranged on the same side of the main unit area 1, which can shorten the carbon dioxide transportation path, and cooperate with the carbon dioxide air bag 5 to realize the storage of carbon dioxide, reducing the requirements for the site selection environment.

[0054] It is understandable that the storage tank bodies can be arranged in a single layer or in multiple layers, and the arrangement of the storage tank bodies can be flexibly adjusted, which will not be described in detail here.

[0055] See Figures 1 to 3 In some embodiments, the hydrogen direct-fired supercritical carbon dioxide energy storage power station further includes an electric control building 7, which is located between the main engine area 1 and the booster station area 6. Furthermore, in some embodiments, the electric control building 7 includes a line room 71, and the booster station area 6 includes a main transformer 61, which is located between the main transformer 61 and the turbine mechanism 12.

[0056] In this embodiment, the booster station area 6 also includes a first transformer 62, a second transformer 63 and a distribution device 64. The main transformer 61, the first transformer 62 and the second transformer 63 are arranged toward the electric control building 7. The first transformer 62 and the second transformer 63 are both high-voltage transformers.

[0057] In this way, the outgoing line room 71 is arranged between the main transformer 61 and the turbine mechanism 12, which can shorten the distance between the outgoing line room 71 and the main transformer 61 and the turbine mechanism 12, reduce the outgoing line bus length of the turbine generator set 121, reduce the bus impedance and bus heat dissipation loss, reduce power loss, and make the structure of the hydrogen direct-fired supercritical carbon dioxide energy storage power station more compact, save floor space, and reduce project costs.

[0058] It is understandable that the position of the outgoing line room 71 can be adjusted according to the positions of the main transformer 61 and the turbine mechanism 12, which will not be described in detail here.

[0059] See Figure 2 and Figure 5In some embodiments, the electric control building 7 further includes a battery room 72, a frequency converter room 73, a low-voltage distribution room 74, a high-voltage distribution room 75, an excitation room 76, an engineer station 77, a centralized control room 78, and an electronic equipment room 79. This can reduce the length of electrical cables and control cables.

[0060] It can be understood that the electric control building 7 can be a single-story structure or a double-story structure. The engineer station 77, the centralized control room 78 and the electronic equipment room 79 can be set on the second floor of the electric control building 7 to save the floor space of the electric control building 7. The battery room 72, the inverter room 73, the low-voltage distribution room 74, the high-voltage distribution room 75 and the excitation room 76 are set on the first floor to facilitate connection with other equipment.

[0061] See Figure 3 In some embodiments, the heat storage area 4 includes a heat storage cold water tank 41 and a heat storage hot water tank 42 , and the heat storage cold water tank 41 and the heat storage hot water tank 42 are arranged on the same side of the boosting station area 6 .

[0062] In this embodiment, the heat storage area 4 also includes a cable tower 43 and a heat storage auxiliary facilities area 44. The cable tower 43 and the heat storage auxiliary setting area are arranged between the heat storage cold water tank 41, the heat storage hot water tank 42 and the booster station area 6. The heat storage auxiliary facilities area 44 includes a heat storage circulating water pump, a heat release circulating water pump, a nitrogen production device, a heat storage water supply pump, and a constant pressure pump.

[0063] In this way, the heat storage cold water tank 41, the heat storage hot water tank 42 and the heat storage auxiliary facilities area 44 are integrated, which not only reduces the footprint of the heat storage area 4 and makes the overall structure of the hydrogen direct-fired supercritical carbon dioxide energy storage power station more compact, but also facilitates the heat storage auxiliary facilities area 44 to regulate the heat storage cold water tank 41 and the heat storage hot water tank 42, reduces the length of the inlet pipe of the heat storage circulating water pump, reduces the cavitation margin requirements of the heat storage circulating water pump and the heat release circulating water pump, improves the circulation and heat exchange efficiency, and enables the heat storage cold water tank 41 and the heat storage hot water tank 42 to maintain a stable pressure during the operation of the heat storage area 4.

[0064] It is understandable that multiple heat storage cold water tanks 41 and heat storage hot water tanks 42 can be provided, and the number of heat storage cold water tanks 41 and heat storage hot water tanks 42 can be adjusted according to actual needs, which will not be elaborated here.

[0065] See Figure 1 In some embodiments, the hydrogen direct-fired supercritical carbon dioxide energy storage power station further includes a water service area 10 , which is arranged on a side of the heat storage area 4 away from the main engine area 1 .

[0066] In this embodiment, the water district 10 includes an industrial wastewater collection pool 101, a chemical water treatment workshop 102, a comprehensive water pump area 103, a mechanical ventilation cooling tower 104 and a fire water pool 105. The mechanical ventilation cooling tower 104 and the comprehensive water pump area 103 are arranged at intervals, and the fire water pool 105, the industrial wastewater collection pool 101 and the chemical water treatment workshop 102 are all arranged on the side of the comprehensive water pump area 103 away from the mechanical ventilation cooling tower 104.

[0067] In this way, the comprehensive water pump area 103 is set close to the mechanical ventilation cooling tower 104, which can reduce the inlet resistance and power consumption of the circulating water pump in the comprehensive water pump area 103 and save electricity. The water area 10 is set on the side of the main unit area 1, which not only reduces the floor area of ​​the main unit area 1, but also facilitates access to external water source pipelines, while shortening the length of pipelines such as cooling water pipelines and fire water pump inlet pipelines.

[0068] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
