DETAILED DESCRIPTION

[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0027] like Figure 1 As shown, the system for preparing hydrogen and oxygen by electrolyzing water coupled with gas turbine power generation and hydrogen and oxygen transportation in the embodiment of the utility model includes a power grid 1, a power generation subsystem, a water electrolysis subsystem, a compression subsystem and a generator set.

[0028] The power generation subsystem is electrically connected to the power grid 1, and the power generation subsystem generates electricity using renewable energy.

[0029] The water electrolysis subsystem utilizes the electrical energy provided by the power generation subsystem to electrolyze water to produce oxygen and hydrogen.

[0030] The compression subsystem includes a first oxygen compressor 22 and a first hydrogen compressor 11. The first oxygen compressor 22 can be connected to the water electrolysis subsystem to compress the oxygen produced by the water electrolysis subsystem, and the first hydrogen compressor 11 can be connected to the water electrolysis subsystem to compress the hydrogen produced by the water electrolysis subsystem.

[0031] The generator set includes a gas turbine and a generator 17 . The gas turbine is connected to the generator 17 , and the generator 17 transmits the generated electrical energy to the power grid 1 .

[0032] The first oxygen compressor 22, the first hydrogen compressor 11 and the gas turbine are coaxially connected, and the rotating shaft of the gas turbine drives the rotating shafts of the first oxygen compressor 22 and the first hydrogen compressor 11 to rotate when rotating.

[0033] The gas turbine comprises a combustion chamber 15 , and the outlet of the first hydrogen compressor 11 can be communicated with the combustion chamber 15 .

[0034] For example, the power generation subsystem generates electricity driven by wind, light or water power, and part of the electricity generated can be directly transmitted to the power grid 1 through the circuit, and the excess electricity is stored for use by the water electrolysis subsystem. The water electrolysis and hydrogen and oxygen production coupled with the gas turbine power generation and hydrogen and oxygen delivery system of the utility model embodiment uses renewable energy for power generation, which not only saves traditional fossil energy, but also reduces pollution to the environment.

[0035] The oxygen and hydrogen produced by the water electrolysis subsystem are respectively transported to the first oxygen compressor 22 and the first hydrogen compressor 11 through pipelines. The first oxygen compressor 22 and the first hydrogen compressor 11 can compress oxygen and hydrogen into high-pressure gas.

[0036] The rotating shaft of the first oxygen compressor 22, the rotating shaft of the first hydrogen compressor 11 and the rotating shaft of the gas turbine are connected through the coupling 12. When the gas turbine is running, it can drive the first oxygen compressor 22 and the first hydrogen compressor 11 to run, so as to compress hydrogen and oxygen into high-pressure gas. At the same time, when the gas turbine is running, the gas turbine can drive the generator 17 to run to generate electrical energy after doing work, and the electrical energy generated by the generator 17 can be transmitted to the power grid 1 for users to use.

[0037] Optionally, the first oxygen compressor 22, the first hydrogen compressor 11 and the gas turbine can be arranged flexibly, for example, the first oxygen compressor 22, the first hydrogen compressor 11 and the gas turbine are arranged in sequence, the first oxygen compressor 22, the gas turbine and the first hydrogen compressor 11 are arranged in sequence, etc. The specific arrangement can be designed according to the site conditions. The rotating shafts of the two adjacent bodies are connected by a coupling 12. In addition, auxiliary devices such as a transmission can also be provided.

[0038] In the related art, the gas pressure boosting process must be equipped with a boosting device such as a compressor 14, and these boosting devices need to consume additional electricity from the power grid 1, especially when the pressure to be boosted is high, a large amount of electricity is consumed, which increases the energy consumption and operating cost of the system. In the present application, the shaft work generated by the gas turbine during operation is transferred to the first oxygen compressor 22 and the first hydrogen compressor 11, and then the hydrogen and oxygen are compressed, and the gas can be compressed without the additional use of the power grid 1, and the power consumption is small, thereby significantly reducing the energy consumption of the system.

[0039] In addition, the gas turbine is a hydrogen gas turbine, and the hydrogen compressed by the first hydrogen compressor 11 can be transported to the combustion chamber 15 for combustion, thereby further reducing the energy consumption required for compressing the hydrogen.

[0040] Therefore, the hydrogen and oxygen production by electrolysis of water coupled with gas turbine power generation and hydrogen and oxygen transportation system in the embodiment of the utility model has the advantage of low energy consumption.

[0041] In some embodiments, Figure 1 As shown, the system for producing hydrogen and oxygen by electrolyzing water and coupling gas turbine power generation and hydrogen and oxygen transportation also includes an oxygen supply subsystem 221 and a hydrogen supply subsystem 111. The oxygen supply subsystem 221 is connected to the first oxygen compressor 22, and the hydrogen supply subsystem 111 is connected to the first hydrogen compressor 11. The oxygen supply subsystem 221 and the oxygen supply subsystem 221 both include multi-stage gas supply systems.

[0042] The oxygen supply subsystem 221 includes a multi-stage supply system, and each stage supply system has a different oxygen pressure. For example, a primary oxygen supply system, a secondary oxygen supply system, a tertiary oxygen supply system, etc. A multi-stage exhaust is set in the first oxygen compressor 22 to obtain compressed oxygen of different pressure levels. According to the pressure requirements of the supply, different supply systems are selected for long-distance transmission so that the compressed oxygen reaches the target location.

[0043] The hydrogen supply subsystem 111 includes a multi-stage supply system, and the hydrogen pressure of each stage supply system is different. For example, a primary hydrogen supply system, a secondary hydrogen supply system, a tertiary hydrogen supply system, etc. A multi-stage exhaust is set in the first hydrogen compressor 11 to obtain compressed hydrogen of different pressure levels. According to the pressure requirements of the gas supply, different gas supply systems are selected for long-distance transmission so that the compressed hydrogen reaches the target location.

[0044] For example, Figure 1 As shown, there are three lines between the first oxygen compressor 22 and the oxygen supply subsystem 221, indicating that the oxygen supply subsystem 221 has a primary oxygen supply system, a secondary oxygen supply system, and a tertiary oxygen supply system. There are three lines between the first hydrogen compressor 11 and the hydrogen supply subsystem 111, indicating that the hydrogen supply subsystem 111 has a primary hydrogen supply system, a secondary hydrogen supply system, and a tertiary hydrogen supply system.

[0045] Optionally, the multi-stage air supply system may be a two-stage air supply system to a six-stage air supply system, etc.

[0046] Therefore, the hydrogen and oxygen production by electrolysis of water coupled with gas turbine power generation and hydrogen and oxygen transportation system of the embodiment of the utility model adopts graded gas supply, so that graded utilization of gas supply pressure can be achieved, thereby facilitating the transportation of hydrogen and oxygen.

[0047] In some embodiments, the system for producing hydrogen and oxygen by electrolyzing water and coupling gas turbine power generation and hydrogen and oxygen transportation also includes a hydrogen storage tank 19, the inlet of the hydrogen storage tank 19 is connected to the first hydrogen compressor 11, and the outlet of the hydrogen storage tank 19 is connected to the combustion chamber 15.

[0048] A flow regulating device 20 is also provided on the pipeline between the outlet of the hydrogen storage tank 19 and the combustion chamber 15. A portion of the hydrogen compressed by the first hydrogen compressor 11 can be stored in the hydrogen storage tank 19 for use by the combustion chamber 15. When it is necessary to adjust the flow of hydrogen entering the combustion chamber 15, the flow regulating device 20 can be controlled.

[0049] In some embodiments, Figure 1 As shown, the compression subsystem also includes an oxygen pipeline, which can connect the water electrolysis subsystem and the first oxygen compressor 22. The second oxygen compressor 7, the oxygen storage device 9 and the oxygen flow regulating device 23 are arranged in sequence on the oxygen pipeline. The second oxygen compressor 7 is arranged adjacent to the water electrolysis subsystem relative to the oxygen flow regulating device 23.

[0050] The oxygen pipeline is used to transport the oxygen produced by the water electrolysis subsystem to the first oxygen compressor 22. Compared with the first oxygen compressor, the second oxygen compressor 7 has a smaller compression capacity than the first oxygen compressor. The second oxygen compressor 7, the oxygen storage device 9, the oxygen flow regulating device 23 and the first oxygen compressor 22 are arranged in sequence. The oxygen produced by the water electrolysis subsystem is preliminarily compressed in the second oxygen compressor 7 and then stored in the oxygen storage device 9. The oxygen flow regulating device 23 is used to regulate the oxygen flow entering the first oxygen compressor 22. For example, during the peak period of oxygen use, the oxygen flow regulating device 23 increases the oxygen flow. During the low-peak period of oxygen use, the oxygen flow regulating device 23 reduces the oxygen flow.

[0051] The electrolysis of water to produce hydrogen and oxygen coupled with gas turbine power generation and hydrogen and oxygen delivery system of the embodiment of the utility model can use the second oxygen compressor 7 to preliminarily compress the oxygen obtained from the electrolysis of water subsystem, so that the volume of oxygen is preliminarily reduced, and it is more convenient for the subsequent further compression work of the first oxygen compressor 22, thereby reducing the workload of the first oxygen compressor 22, and thus improving the efficiency and stability of the entire compression process. The oxygen storage device 9 can temporarily store the preliminarily compressed oxygen so that the first oxygen compressor 22 can obtain it in time when needed, thereby ensuring a continuous supply of oxygen.

[0052] In some embodiments, Figure 1As shown, the compression subsystem also includes a hydrogen pipeline, which can connect the water electrolysis subsystem and the first hydrogen compressor 11. The second hydrogen compressor 6, the hydrogen storage device 8 and the hydrogen flow regulating device 10 are arranged in sequence on the hydrogen pipeline. The second hydrogen compressor 6 is arranged adjacent to the water electrolysis subsystem relative to the hydrogen flow regulating device 10.

[0053] The hydrogen pipeline is used to transport the hydrogen produced by the water electrolysis subsystem to the first hydrogen compressor 11. Compared with the first hydrogen compressor, the second hydrogen compressor 6 has a smaller compression capacity than the first hydrogen compressor. The second hydrogen compressor 6, the hydrogen storage device 8, the hydrogen flow regulating device 10 and the first hydrogen compressor 11 are arranged in sequence. The hydrogen produced by the water electrolysis subsystem is preliminarily compressed in the second hydrogen compressor 6 and then stored in the hydrogen storage device 8. The hydrogen flow regulating device 10 is used to regulate the flow of hydrogen entering the first hydrogen compressor 11. For example, during the peak period of hydrogen consumption, the hydrogen flow regulating device 10 increases the hydrogen flow. During the low-peak period of hydrogen consumption, the hydrogen flow regulating device 10 reduces the hydrogen flow.

[0054] The electrolysis of water to produce hydrogen and oxygen coupled with a gas turbine power generation and hydrogen and oxygen delivery system of the embodiment of the utility model can use the second hydrogen compressor 6 to preliminarily compress the hydrogen obtained from the water electrolysis subsystem, so that the volume of the hydrogen is preliminarily reduced, and it is more convenient for the subsequent further compression work of the first hydrogen compressor 11, thereby reducing the workload of the first hydrogen compressor 11, and thus improving the efficiency and stability of the entire compression process. The hydrogen storage device 8 can temporarily store the preliminarily compressed hydrogen so that the first hydrogen compressor 11 can obtain it in time when needed, thereby ensuring a continuous supply of hydrogen.

[0055] In some embodiments, the power generation subsystem includes a renewable energy power generation device 2 , a rectifier 3 and a power storage device 4 , and the renewable energy power generation device 2 is electrically connected to the power storage device 4 via the rectifier 3 .

[0056] For example, part of the electric energy generated by the renewable energy power generation device 2 is transmitted to the power grid 1 , and the other part can be transmitted to the power storage device 4 after being rectified by the rectifier 3 .

[0057] The electrolysis of water to produce hydrogen and oxygen coupled with a gas turbine power generation and hydrogen and oxygen delivery system of the utility model embodiment uses renewable energy for power generation, which not only saves traditional fossil energy but also reduces environmental pollution. The power storage device 4 can temporarily store electrical energy so that the electrolysis water subsystem can obtain it in time when needed, thereby ensuring a continuous supply of oxygen and hydrogen.

[0058] In some embodiments, Figure 1As shown, the water electrolysis subsystem includes a water electrolysis device 5, which is electrically connected to the power storage device 4. The water electrolysis device 5 uses the electrical energy provided by the power storage device 4 to produce hydrogen and oxygen.

[0059] The power storage device 4 provides electric energy for the water electrolysis subsystem. During the peak period of gas consumption, when the amount of hydrogen and oxygen required downstream is large, the output power of the power storage device increases to speed up the production of hydrogen and oxygen by the water electrolysis subsystem. During the low-peak period of gas consumption, the output power of the power storage device 4 decreases.

[0060] Therefore, the water electrolysis for preparing hydrogen and oxygen coupled with gas turbine power generation and hydrogen and oxygen transportation system of the embodiment of the utility model can flexibly adjust the operation of the water electrolysis subsystem according to the demand for downstream gas supply by setting up the power storage device 4, thereby improving the stability of power generation.

[0061] In some embodiments, the gas turbine further includes a compressor 14 and a turbine 16, wherein the compressor 14, the combustion chamber 15 and the turbine 16 are arranged in sequence. The compressor 14 is used to compress the gas and then provide it to the combustion chamber 15. After the fuel is burned in the combustion chamber 15, a large amount of heat energy is released, which drives the turbine 16 to do work.

[0062] In some embodiments, Figure 1 As shown, the gas turbine further includes an air supply system 21, which can be communicated with the compressor 14. The air supply system 21 is communicated with the compressor 14 so as to provide air into the compressor 14.
