Description

Technical Field

[0001] This invention relates to the field of gas energy storage technology, and more specifically to a gas energy storage device. Background Technology

[0002] Gas energy storage refers to an energy storage method that uses electrical energy to compress gas during periods of low grid load and releases the compressed gas to drive a steam turbine to generate electricity during periods of high grid load. This method can store intermittent renewable energy sources such as wind, solar, and tidal power during periods of low electricity demand and then output them stably during periods of high demand, thus providing an effective solution for the large-scale utilization of renewable energy.

[0003] Gas energy storage can utilize a wide variety of gases, including air, pure gases, and industrial flue gas. During energy storage, multi-stage cooling is required during gas compression to reduce energy consumption. Conversely, during energy release, the compressed gas needs to be heated to fully release its stored energy. However, current technologies offer limited research on energy distribution during storage and release, often relying on external cold and heat sources for cooling and heating respectively. This approach fails to optimize energy utilization during storage and release, resulting in increased energy consumption.

[0004] Furthermore, the gases used in gas energy storage typically contain components such as carbon dioxide and oxygen, which are widely used in industrial production and manufacturing. Therefore, it is necessary to separate some target components during the gas energy storage process to improve economic efficiency. Summary of the Invention

[0005] In view of the above-mentioned problems in the prior art, the present invention provides a gas energy storage device that can make reasonable use of energy during the energy storage and release process in order to reduce energy consumption, and can separate the target components during the gas energy storage process to improve economic efficiency.

[0006] The technical solution adopted by this invention to solve its technical problem is: to provide a gas energy storage device, comprising,

[0007] An energy storage assembly for inputting a first gas includes a first adsorber, a second compressor connected to the first adsorber, and a second adsorber connected to the second compressor. The first adsorber is configured to adsorb a target gas from the first gas and obtain a second gas.

[0008] The second compressor is configured to compress the second gas, thereby heating the second adsorber, which has already adsorbed the target gas, after the second gas is heated to a higher temperature, thus causing the target gas to desorb from the second adsorber.

[0009] Furthermore, the first adsorber is provided with an adsorbent inside, which is used to adsorb the target gas after the first gas enters the first adsorber.

[0010] Furthermore, the first adsorber is provided with a first input terminal for inputting the first gas and a first output terminal for outputting the second gas. The first output terminal is connected to the second compressor to compress the second gas.

[0011] Furthermore, the second adsorber includes a second input terminal connected to the second compressor and a second output terminal for communicating with the second input terminal. The second adsorber contains an adsorbent that has adsorbed the target gas. The second adsorber is configured to heat the adsorbent that has adsorbed the target gas when the second compressor delivers the compressed second gas from the second input terminal to the second output terminal.

[0012] Furthermore, the structure of the second adsorber is the same as that of the first adsorber, and the first output end of the second adsorber is connected to a storage tank for storing the target gas desorbed from the adsorbent of the second adsorber.

[0013] Furthermore, the second output terminal is connected to a third compressor for compressing the second gas flowing out of the second adsorber.

[0014] Furthermore, the target gas is carbon dioxide.

[0015] Furthermore, the gas energy storage device also includes an energy release component and an energy storage container connected to the energy release component and the energy storage component for storing the compressed second gas. The energy release component includes a heat exchanger connected to the energy storage container, and the heat exchanger is configured to heat the second gas output from the energy storage container.

[0016] Furthermore, the heat exchanger is connected to a third adsorber with the same structure as the first and second adsorbers, and a storage container for storing the heat exchange medium. The heat exchanger is configured to transfer the heat absorbed by the heat exchange medium when the energy storage component is operating and flowing through the third adsorber to the second gas output from the energy storage container when the energy release component is operating.

[0017] Furthermore, a cooler is provided between the storage container and the third adsorber to assist in cooling the heat exchange medium, so that the third adsorber can be cooled by the cooled heat exchange medium only when the energy storage component is running.

[0018] Furthermore, a heater is provided between the storage container and the heat exchanger to assist in heating the heat exchange medium, so that the second gas output from the energy storage container can be heated by the heated heat exchange medium when only the energy release component is running.

[0019] Furthermore, the first adsorber is configured to be installed at the position of the second adsorber after adsorbing the target gas, the second adsorber is configured to be installed at the position of the third adsorber after desorbing the target gas, and the third adsorber is configured to be installed at the position of the first adsorber after cooling.

[0020] The beneficial effects of this invention are as follows: This invention provides a gas energy storage device, comprising an energy storage component for inputting a first gas. The energy storage component includes a first adsorber, a second compressor connected to the first adsorber, and a second adsorber connected to the second compressor. The first adsorber is configured to adsorb a target gas from the first gas, obtaining a second gas. The second compressor is configured to compress the second gas, causing the second gas to heat the second adsorber, which has already adsorbed the target gas, after its temperature rises, thereby desorbing the target gas from the second adsorber. This separates the target gas from the first gas during the gas energy storage process, improving economic efficiency. Furthermore, it rationally utilizes the heat of the second gas after compression by the second compressor, reducing the energy consumption of the gas energy storage device.

[0021] Furthermore, the gas energy storage device can use the second adsorber after desorption of the second gas as a third adsorber, which is cooled by a heat exchanger during the energy release process. This rationally utilizes the heat generated during energy storage for the energy release process, thereby further reducing energy consumption. The cooled third adsorber can then function as the first adsorber, ensuring the continuous operation of the gas energy storage device. In addition, the heat exchanger, in conjunction with a cooler and a heater, allows the energy storage and energy release processes of the gas energy storage device to be performed independently or simultaneously, thus improving the flexibility of the gas energy storage device.

[0027] To make the technical problem to be solved, the technical solution, and the beneficial effects of this invention clearer, the invention will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, illustrating only the basic structure of the invention, and therefore only shows the components relevant to the invention. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0028] refer to Figure 1 As shown, the gas energy storage device 100 provided by the present invention includes an energy storage component 10, an energy release component 20 connected to the energy storage component 10, and an energy storage container 30 communicating with the energy storage component 10 and the energy release component 20. The energy storage component 10 is configured to separate a target gas and a second gas from an input first gas, thereby improving economic efficiency. Furthermore, the energy storage component 10 can compress the separated second gas to convert excess electrical energy during off-peak hours into the pressure potential energy of the second gas. The compressed second gas is stored in the energy storage container 30 and then released through the energy release component 20 during peak hours to convert the pressure potential energy back into electrical energy.

[0029] It should be understood that the first gas input to the energy storage component 10 of the gas energy storage device 100 is a mixed gas, which includes at least a target gas and a second gas. The target gas can be one or more gases, such as carbon dioxide, oxygen, etc. The second gas can also be one or more gases, such as nitrogen, rare gases, etc.

[0030] In some implementations, the first gas can be air, industrial flue gas, or flue gas emitted from a power plant.

[0031] Combination Figure 1As shown, in some embodiments, the energy storage component 10 includes a filter 11 for inputting a first gas, a first compressor 12 connected to the filter 11, and a first adsorber 13 connected to the first compressor 12. The filter 11 is used to filter impurities mixed in the first gas. The impurities can be solid impurities, such as dust, or liquid impurities, such as tiny water droplets. Preferably, the filter 11 can also absorb water vapor in the first gas to dry the first gas, thereby preventing the water vapor in the first gas from liquefying during subsequent compression and preventing the water vapor from having an adverse effect during the subsequent separation of the target gas.

[0032] In some embodiments, the input end of the first compressor 12 is connected to the output end of the filter 11 via a pipe, and the output end of the first compressor 12 is connected to the first adsorber 13 via a pipe. The first compressor 12 performs a first-stage compression on the first gas filtered by the filter 11, and then delivers the compressed gas to the first adsorber 13.

[0033] In some embodiments, the first adsorber 13 includes a first input terminal 131 for communication with the first compressor 12 and a first output terminal 132 for communication with the second compressor 14. The first adsorber 13 is filled with an adsorbent for adsorbing the target gas mixed in the first gas. After the first compressor 12 delivers the compressed first gas from the first input terminal 131 into the first adsorber 13, the adsorbent in the first adsorber 13 adsorbs the target gas, while the second gas that cannot be adsorbed by the adsorbent flows through the first output terminal 132 to the second compressor 14.

[0034] In this embodiment, the target gas is carbon dioxide, and the adsorbent is a carbon dioxide adsorbent. Preferably, the adsorbent is a physical adsorbent, such as activated carbon or zeolite molecular sieves. The adsorbent adsorbs carbon dioxide by means of intermolecular attraction between its surface molecules and carbon dioxide molecules. This adsorption method is reversible; carbon dioxide can be desorbed by reducing the partial pressure or increasing the temperature. This effectively reduces the difficulty of separating and extracting carbon dioxide.

[0035] In some embodiments, the first compressor 12 performs a first-stage compression on the first gas, which can effectively increase the density of the first gas when it is delivered to the first adsorber 13, thereby improving the processing efficiency of the energy storage component 10 for the first gas. Therefore, in order to ensure the adsorption rate and adsorption efficiency of the first adsorber 13 for the target gas, the temperature of the first gas should not rise significantly after the first-stage compression.

[0036] In some preferred embodiments, multiple first adsorbers 13 can be connected in series between the first compressor 12 and the second compressor 14 to improve the adsorption rate of the target gas. Different types of adsorbents can be filled into the multiple first adsorbers 13 to adsorb various target gases mixed in the first gas.

[0037] In some preferred embodiments, multiple first adsorbers 13 can also be connected in parallel between the first compressor 12 and the second compressor 14 to increase the throughput of the first gas.

[0038] Recombined Figure 1 As shown, in some embodiments, the second adsorber 15 includes a second input terminal 151 for communication with the second compressor 14 and a second output terminal 152 for communication with the third compressor 16. The interior of the second adsorber 15 is filled with adsorbent that has already adsorbed the target gas. The second input terminal 151 and the second output terminal 152 are connected inside the second adsorber 15 via pipes, so that the second gas delivered to the second adsorber 15 after the second stage compression by the second compressor 14 is separated from the adsorbent that has already adsorbed the target gas, thereby preventing the second gas from re-mixing with the desorbed target gas. The desorbed target gas can flow through a pipe to the storage tank 17 for storage.

[0039] In some embodiments, the second compressor 14 performs a second-stage compression on the second gas, which can effectively increase the pressure potential energy of the second gas. However, during the second-stage compression process, the work done by the second compressor 14 on the second gas also causes the temperature of the second gas to rise. Therefore, the second compressor 14 inputs the second gas, which has undergone second-stage compression, into the second adsorber 15 from the second input end 151, which can heat the adsorbent that has adsorbed the target gas, thereby improving the desorption rate and desorption efficiency of the target gas. Furthermore, this is also a cooling process for the second gas. After passing through the second adsorber 15, the temperature of the second gas decreases. This reduces the difficulty for the third adsorber 16 to compress the second gas output from the second output end 152. This effectively utilizes the heat of the second gas after compression by the second compressor 14, reducing the energy consumption of the gas storage device 100 to a certain extent.

[0040] In some embodiments, the second compressor 14 compresses the separated second gas at a higher rate than the first compressor 12 compresses the first gas.

[0041] In some preferred embodiments, the compression ratio of the separated second gas by the second compressor 14 is at least 5 times that of the compression ratio of the first gas by the first compressor 12, and may also be 10 times, 20 times, 30 times, etc.

[0042] In some preferred embodiments, the second adsorber 15 has the same structure as the first adsorber 13. This allows the first adsorber 13, which has reached saturation adsorption, to be installed between the second compressor 14 and the third compressor 16, so that the first adsorber 13, which has reached saturation adsorption, functions as the second adsorber 15, thereby desorbing the adsorbed target gas. Therefore, the first output end 132 of the second adsorber 15 can be connected to the storage tank 17 via a pipeline to transport the desorbed target gas to the storage tank 17 for storage.

[0043] Similarly, the second adsorber 15, which has reached a fully desorbed state, can be installed between the first compressor 12 and the second compressor 14 so that the second adsorber 15, which has reached a fully desorbed state, can be used as the first adsorber 13 after cooling, thereby continuing to adsorb the target gas in the first gas.

[0044] Recombined Figure 1 As shown, in some embodiments, the input end of the third compressor 16 is connected to the second output end 152 of the second adsorber 15 via a pipe, and the output end of the third compressor 16 is connected to the input end of the energy storage container 30 via a pipe. The third compressor 16 performs a third-stage compression on the second gas delivered from the second adsorber 15, so that the pressure of the second gas is the same as the pressure inside the energy storage container 30, so as to deliver the second gas into the energy storage container 30.

[0045] As is easily understood, the energy storage container 30 can be a man-made container such as a storage tank or storage box with an internal cavity. Multiple energy storage containers 30 can be arranged, and the multiple energy storage containers 30 can be connected in series and / or parallel.

[0046] In some other preferred embodiments and implementations, the third compressor 16 can also deliver the second gas after the third stage of compression to abandoned mines, caves, expired oil and gas wells or newly built gas storage wells with internal cavities for storage.

[0047] Recombined Figure 1 As shown, in some embodiments, the energy release assembly 20 includes a first expander 21 connected to the output end of the energy storage container 30, and a second expander 22 connected to the first expander 21. The first expander 21 is used to perform a first-stage expansion of the second gas supplied from the energy storage container 30, and the second expander 22 is used to perform a second-stage expansion of the second gas supplied from the first expander 21. Both the first expander 21 and the second expander 22 are configured to convert the pressure potential energy of the second gas into electrical energy during the expansion process, so as to provide power supply during peak electricity consumption periods. Specifically, the first expander 21 and the second expander 22 can be steam turbines.

[0048] In some embodiments, the energy release assembly 20 further includes a heat exchanger 23 connected to the energy storage container 30, and the heat exchanger 23 is connected to a storage container 24 for storing the heat exchange medium. The heat exchanger 23 is capable of transferring heat from the heat exchange medium to the second gas output from the energy storage container 30, thereby heating the second gas and allowing its pressure potential energy to be fully released.

[0049] In this embodiment, the heat exchanger 23 is disposed on the pipeline between the first expander 21 and the second expander 22. The heat exchanger 23 heats the second gas only after the first expander 21 has performed a first-stage expansion on the second gas output from the energy storage container 30. This ensures that the pressure potential energy of the second gas can be fully released, and also guarantees the safety of the energy release component 20.

[0050] In some embodiments, heat exchanger 23 is also connected to a third adsorber 25, which has the same structure as the first adsorber 13 and the second adsorber 15. The second input terminal 151 and the second output terminal 152 of the third adsorber 25 are respectively connected to the storage container 24 and the heat exchanger 23. The second adsorber 15, having reached a fully desorbed state, is installed between the heat exchanger 23 and the storage container 24, so that the fully desorbed second adsorber 15 serves as the third adsorber 25, thereby heating the heat exchange medium flowing to the heat exchanger 23. This is also the process of cooling the third adsorber 25. Therefore, the cooled third adsorber 25 can be installed between the first compressor 12 and the second compressor 14, so that it can continue to adsorb the target gas in the first gas as the first adsorber 13.

[0051] In some preferred embodiments, when only the energy storage component 10 is operating, the storage container 24 can continuously store the high-temperature heat exchange medium flowing through the third adsorber 25, so as to heat the second gas output from the energy storage container 30 through the heat exchanger 23 when only the energy release component 20 is operating. Similarly, when only the energy release component 20 is operating, the storage container 24 can continuously store the low-temperature heat exchange medium flowing through the heat exchanger 23, so as to cool the third adsorber 25 when only the energy storage component 10 is operating.

[0052] In some preferred embodiments, a cooler 26 is further provided between the storage container 24 and the third adsorber 25 to assist in cooling the heat exchange medium flowing to the third adsorber 25, so that the third adsorber 25 can be cooled by the cooled heat exchange medium. This allows the third adsorber 25 to be cooled only when the energy storage component 10 is running, thereby improving the cooling efficiency and cooling effect of the third adsorber 25.

[0053] In some embodiments not shown, a heater is also provided between the storage container 24 and the heat exchanger 23 to assist in heating the heat exchange medium flowing to the heat exchanger 23, so as to heat the second gas output from the energy storage container 30 through the heated heat exchange medium. This allows the second gas output from the energy storage container 30 to be heated even when only the energy release component 20 is in operation.

[0054] Combination Figure 1 As shown, the energy storage and energy release processes of the gas energy storage device 100 will be described in detail below.

[0055] During the energy storage process, filter 11 delivers the filtered first gas to first compressor 12. First compressor 12 performs a first-stage compression on the delivered first gas and then delivers it to first adsorber 13. First adsorber 13 adsorbs the target gas mixed in the first gas and then delivers the second gas that cannot be adsorbed to second compressor 14. Second compressor 14 performs a second-stage compression on the delivered second gas and then delivers the heated second gas to the second input terminal 151 of second adsorber 15.

[0056] The heated second gas, flowing from the second input end 151 to the second output end 152 of the second adsorber 15, heats the adsorbent in the second adsorber 15 that has already adsorbed the target gas, causing the target gas to desorb from the adsorbent. The desorbed target gas flows from the first output end 132 of the second adsorber 15 to the storage tank 17 for storage. The second gas flowing out from the second output end 152 of the second adsorber 15 flows to the third compressor 16, which performs a third-stage compression on the second gas, making the pressure of the second gas the same as the pressure inside the energy storage container 30, so as to deliver the second gas into the energy storage container 30. This completes the entire energy storage process.

[0057] In the aforementioned energy storage process, the first adsorber 13, which has reached saturated adsorption, can be installed at the position of the second adsorber 15, so that the first adsorber 13, which has reached saturated adsorption, can function as the second adsorber 15. The second adsorber 15, which has reached complete desorption, can be installed at the position of the third adsorber 25, so that the second adsorber 15, which has reached complete desorption, can function as the third adsorber 25. The cooled third adsorber 25 can be installed at the position of the first adsorber 13, so that it can continue to adsorb the target gas in the first gas as the first adsorber 13.

[0058] During the energy release process, the energy storage container 30 delivers the stored second gas to the first expander 21 and the second expander 22. As the second gas expands, the first expander 21 and the second expander 22 convert the pressure potential energy of the second gas into electrical energy, thus completing the entire energy release process.

[0059] During the energy release process described above, the heat exchanger 23 heats the second gas flowing from the first expander 21 to the second expander 22 so that the pressure potential energy of the second gas can be fully released.

[0060] In some embodiments, the energy storage and release processes described above can be performed individually or simultaneously. When the energy storage and release processes are performed simultaneously, the cooler 26 or the heater can be activated. When the operating power of the energy storage component 10 is greater than the operating power of the energy release component 20, the cooler 26 is activated to provide auxiliary cooling for the third adsorber 25. When the operating power of the energy storage component 10 is less than the operating power of the energy release component 20, the heater is activated to provide auxiliary heating for the second gas output from the energy storage container 30. Therefore, by incorporating a cooler and a heater, the flexibility of the gas energy storage device 100 can be significantly improved while effectively reducing energy consumption.
