[0042] The present disclosure provides a carbon dioxide energy storage system SYS, see Figure 1 , the carbon dioxide energy storage system SYS includes a gas storage subsystem 100, an energy storage component 200, an energy storage container 300 and an energy release component 400. The gas storage subsystem 100 is connected to the inlet of the energy storage component 200, the outlet of the energy storage component 200 is connected to the inlet of the energy storage container 300, the outlet of the energy storage container 300 is connected to the inlet of the energy release component 400, and the outlet of the energy release component 400 is connected to the gas storage subsystem 100. The gas storage subsystem 100 can store gaseous carbon dioxide; the energy storage container 300 can store liquid carbon dioxide. The energy storage component 200 can use electricity to compress the gaseous carbon dioxide from the gas storage subsystem 100 to achieve energy storage; the energy release component 400 can expand the carbon dioxide from the energy storage container 300 to generate electricity. The energy storage component 200 can also cool down the compressed gaseous carbon dioxide, for example, cool down the compressed gaseous carbon dioxide to condense into liquid carbon dioxide, or allow the cooled gaseous carbon dioxide to enter the energy storage container 300 and be condensed into liquid carbon dioxide. The energy release component 400 can also heat the carbon dioxide, for example, evaporate the liquid carbon dioxide provided by the energy storage container 300 into gaseous carbon dioxide, then heat it up, and expand the heated gaseous carbon dioxide to generate electricity, or heat the gaseous carbon dioxide provided by pre-evaporation in the energy release component 400, and expand the heated gaseous carbon dioxide to generate electricity.

[0043] For example, in the energy storage stage, the energy storage component 200 can compress and condense the gaseous carbon dioxide from the gas storage subsystem 100, thereby causing the gaseous carbon dioxide to phase-change into liquid carbon dioxide and store it in the energy storage container 300. In the energy release stage, the energy release component 400 can evaporate and expand the liquid carbon dioxide from the energy storage container 300 to generate electricity, thereby causing the generated gaseous carbon dioxide to be stored in the gas storage subsystem 100.

[0044] In one embodiment of the present disclosure, see Figure 2The energy storage assembly 200 includes at least one compressed energy storage unit 201; the compressed energy storage unit 201 includes a compressor 21 and an energy storage heat exchanger 22, and each compressed energy storage unit 201 is connected to the gas storage subsystem 100 and the energy storage container 300. Specifically, the inlet of each compressed energy storage unit 201 is connected to the gas storage subsystem 100, and the outlet of each compressed energy storage unit 201 is connected to the energy storage container 300. The compressor 21 can compress the gaseous carbon dioxide from the gas storage subsystem 100 under electric drive, and the compressed carbon dioxide can be heat exchanged and cooled in the energy storage heat exchanger 22.

[0045] exist Figure 2 In the example, the energy storage assembly 200 includes three compressed energy storage parts 201. It is understood that in other embodiments of the present disclosure, the number of compressed energy storage parts 201 in the energy storage assembly 200 is not limited to 3, for example, it can be 1, or a plurality of other numbers (for example, 2, 4, 5 or 6).

[0046] In one embodiment of the present disclosure, the compressed energy storage unit 201 includes a compressed energy storage unit or a plurality of compressed energy storage units cascaded in sequence. A compressed energy storage unit may include a compressor 21 and an energy storage heat exchanger 22; the outlet of the compressor 21 is connected to the carbon dioxide inlet of the energy storage heat exchanger 22; in this way, after the gaseous carbon dioxide is compressed in the compressor 21, it flows into the energy storage heat exchanger 22 for heat exchange and cooling. When the compressed energy storage unit 201 includes a plurality of compressed energy storage units cascaded in sequence, between two adjacent compressed energy storage units, the carbon dioxide outlet of the energy storage heat exchanger 22 of the upper-stage compressed energy storage unit is connected to the inlet of the compressor 21 of the lower-stage compressed energy storage unit. Figure 2 In the example, the compressed energy storage part 201 includes two compressed energy storage units. It can be understood that, according to needs, the compressed energy storage unit in the compressed energy storage part 201 can be one, or two or more.

[0047] exist Figure 2 In the example, the solid arrows indicate the flow direction of the carbon dioxide in the compressed energy storage unit 201, and the dotted arrows indicate the flow direction of the cooling medium flowing through the energy storage heat exchanger 22. In the energy storage heat exchanger 22, the compressed carbon dioxide with a higher temperature exchanges heat with the cooling medium with a lower temperature, so that the carbon dioxide is cooled and thus facilitates condensation into liquid carbon dioxide, and the cooling medium absorbs heat and heats up to recover the heat generated during the compression of the carbon dioxide.

[0048] In one embodiment of the present disclosure, the inlet of the first-stage compressor 21 of the compressed energy storage part 201 is connected to the gas storage subsystem 100. It is understandable that when the compressed energy storage part 201 has only one compressed energy storage unit, the inlet of the compressor 21 of the compressed energy storage part 201 is connected to the gas storage subsystem 100. Further, a valve may be provided between the inlet of the first-stage compressor 21 and the gas storage subsystem 100.

[0049] In one embodiment of the present disclosure, the compressed energy storage unit 201 may further include a condenser 23, which is disposed between the last stage compressed energy storage unit and the energy storage container 300. In other words, the carbon dioxide outlet of the last stage energy storage heat exchanger 22 may be connected to the carbon dioxide inlet of the condenser 23, and the carbon dioxide outlet of the condenser 23 may be connected to the inlet of the energy storage container 300. The condenser 23 may condense the carbon dioxide from the compressed energy storage unit, so that the carbon dioxide from the compressed energy storage unit is condensed into liquid carbon dioxide and stored in the energy storage container 300.

[0050] In one embodiment of the present disclosure, see Figure 3 , the energy release assembly 400 includes at least one expansion energy release part 401; the expansion energy release part 401 includes a turbine 41 and an energy release heat exchanger 42, and each expansion energy release part 401 is connected to the gas storage subsystem 100 and the energy storage container 300. Specifically, the inlet of each expansion energy release part 401 is connected to the energy storage container 300, and the outlet of each expansion energy release part 401 is connected to the gas storage subsystem 100. The carbon dioxide from the energy storage container 300 can enter the turbine 41 after absorbing heat in the energy release heat exchanger 42, and then drive the turbine 41 to generate electricity.

[0051] exist Figure 3 In the example, the energy release component 400 includes three expansion energy release parts 401. It is understandable that in other embodiments of the present disclosure, the number of expansion energy release parts 401 in the energy release component 400 is not limited to 3, for example, it can be 1, or other numbers (for example, 2, 4, 5 or 6).

[0052] In one embodiment of the present disclosure, the expansion energy release section 401 includes one expansion energy release unit or multiple expansion energy release units cascaded in sequence. One expansion energy release unit may include a turbine 41 and an energy release heat exchanger 42; the carbon dioxide outlet of the energy release heat exchanger 42 is connected to the inlet of the turbine 41; in this way, after carbon dioxide absorbs heat in the energy release heat exchanger 42, it flows into the turbine 41 to expand and generate electricity. When the expansion energy release section 401 includes multiple expansion energy release units cascaded in sequence, between two adjacent expansion energy release units, the outlet of the turbine 41 of the upper-stage expansion energy release unit is connected to the carbon dioxide inlet of the energy release heat exchanger 42 of the lower-stage expansion energy release unit. Figure 3In the example of , the expansion energy release part 401 includes two expansion energy release units. It can be understood that, according to needs, the expansion energy release unit in the expansion energy release part 401 can be one, or two or more.

[0053] exist Figure 3 In the example, the solid arrows indicate the flow direction of the carbon dioxide in the expansion energy release part 401, and the dotted arrows indicate the flow direction of the heating medium flowing through the energy release heat exchanger 42. In the energy release heat exchanger 42, the carbon dioxide that flows out of the energy storage container 300 and expands and cools down exchanges heat with the heating medium with a higher temperature, thereby heating the carbon dioxide, which can recover the cold energy generated by the expansion of the gaseous carbon dioxide.

[0054] In one embodiment of the present disclosure, the outlet of the last stage turbine 41 of the expansion energy release part 401 is connected to the gas storage subsystem 100. It is understandable that when the expansion energy release part 401 has only one expansion energy release unit, the outlet of the turbine 41 of the expansion energy release part 401 is connected to the gas storage subsystem 100. Optionally, a valve is provided between the outlet of the last stage turbine 41 of the expansion energy release part 401 and the gas storage subsystem 100.

[0055] In one embodiment of the present disclosure, the expansion energy release part 401 may further include an evaporator 43, which is disposed between the first-stage expansion energy release unit and the energy storage container 300. In other words, the carbon dioxide inlet of the first-stage energy release heat exchanger 42 may be connected to the carbon dioxide outlet of the evaporator 43, and the carbon dioxide inlet of the evaporator 43 may be connected to the outlet of the energy storage container 300. The evaporator 43 may heat the liquid carbon dioxide from the energy storage container 300, so that the liquid carbon dioxide from the energy storage container 300 evaporates into gaseous carbon dioxide and flows into the energy release heat exchanger 42.

[0056] It is understood that in other embodiments of the present disclosure, the carbon dioxide energy storage system SYS may also be provided with other components. In one example, the carbon dioxide energy storage system SYS may also be provided with a heat recovery component, which includes a heat storage tank and a cold storage tank. In the energy storage stage, the energy storage heat exchanger 22 may exchange heat with the low-temperature medium from the cold storage tank (i.e., the cooling medium flowing into the energy storage heat exchanger 22), so that the carbon dioxide in the energy storage heat exchanger 22 is cooled down, and the low-temperature medium is heated to a high-temperature medium and stored in the heat storage tank. In the energy release stage, the energy release heat exchanger may exchange heat with the high-temperature medium from the heat storage tank (i.e., the heating medium flowing into the energy release heat exchanger 42), so that the carbon dioxide in the energy release heat exchanger is heated up, and the high-temperature medium is cooled to a low-temperature medium and stored in the cold storage tank. In this example, the heating medium and the cooling medium are heat exchange media circulating between the heat storage tank and the cold storage tank, and the temperature states of the two are different.

[0057] exist Figure 1~Figure 3 In the example, the number of energy storage containers 300 is one. It is understandable that in the embodiment of the present disclosure, the number of energy storage containers 300 may also be multiple. When the number of energy storage containers 300 is multiple, these energy storage containers 300 may be connected in series, or in parallel, or may be connected in a mixed manner of series and parallel.

[0058] In one embodiment of the present disclosure, see Figure 1 The gas storage subsystem 100 includes a pipeline structure 120 and at least one gas storage reservoir component 110 connected to the pipeline structure 120. The pipeline structure 120 is connected to at least one of the energy storage component 200 and the energy release component 400. For example, Figure 1 In the example, the pipeline structure 120 is connected to the inlet of the energy storage component 200 and the outlet of the energy release component 400 at the same time. In this way, in the energy storage stage, the gaseous carbon dioxide stored in the gas storage component 110 can flow into the energy storage component 200 through the pipeline structure 120; in the energy release stage, the gaseous carbon dioxide flowing out of the energy storage container 300 can flow into the gas storage component 110 through the pipeline structure 120. It can be understood that in other embodiments of the present disclosure, the pipeline structure 120 may not be provided in the gas storage subsystem 100, but the gas storage component 110 is directly connected to the energy storage component 200 and the energy release component 400. For example, in Fig.14 In the example, the gas storage subsystem 100 has only one gas storage reservoir component 110, and the gas storage reservoir component 110 can be directly connected to the energy storage component 200 and the energy release component 400; a valve is provided between the gas storage reservoir component 110 and the energy storage component 200, and a valve is provided between the gas storage reservoir component 110 and the energy release component 400.

[0059] exist Figure 1 In the example, the gas storage subsystem 100 includes a plurality of gas storage reservoir components 110; it can be understood that in other embodiments of the present disclosure, the number of gas storage reservoir components 110 in the gas storage subsystem 100 may also be one.

[0060] exist Figure 1In the example, multiple gas storage reservoir components 110 are connected to the pipeline structure 120. Therefore, when multiple gas storage subsystems 100 provide gaseous carbon dioxide to the energy storage component 200, the pipeline structure 120 can rebalance the airflow rate and air pressure, which is conducive to maintaining a stable airflow output of the gas storage subsystem 100 on the one hand, and on the other hand, it is conducive to balancing the airflow rate of each gas storage reservoir component 110, so that the airflow rate of each gas storage reservoir component 110 is roughly consistent. This helps to improve the overall efficiency of the carbon dioxide energy storage system SYS. Similarly, when the energy release component 400 provides gaseous carbon dioxide to multiple gas storage reservoir components 110, the pipeline structure 120 can rebalance the airflow rate and air pressure, which is conducive to balancing the air intake flow of each gas storage reservoir component 110, so that the air intake flow of each gas storage reservoir component 110 is roughly consistent.

[0061] In some embodiments of the present disclosure, see Figure 4~Figure 13 The gas storage assembly 110 includes a gas storage 111, a gas distribution pipe 112 and a connecting pipe 113. The gas distribution pipe 112 has a plurality of gas ports 117 connected to the gas storage space 111a of the gas storage 111; the first end of the connecting pipe 113 is connected to the gas distribution pipe 112, and the second end 113a of the connecting pipe 113 is directly or through a pipeline structure connected to at least one of the energy storage assembly and the energy release assembly. Optionally, the second end 113a of the connecting pipe 113 is located outside the range of the gas storage 111.

[0062] For example, in one example, the second end of the connecting tube 113 is connected to the pipeline structure 120 , and the pipeline structure 120 is connected to the energy storage assembly 200 and the energy release assembly 400 .

[0063] For another example, in another embodiment, the second end of the connecting tube 113 is directly connected to the energy storage assembly 200 and the energy release assembly 400 .

[0064] In these embodiments, the gas distribution pipe 112 has a plurality of gas ports 117 connected to the gas storage space 111a of the gas storage reservoir 111. In the energy storage stage, the gaseous carbon dioxide in the gas storage space 111a of the gas storage reservoir 111 can enter the gas distribution pipe 112 through the gas ports 117, and then flow out of the gas storage reservoir 111 through the gas distribution pipe 112 and the connecting pipe 113 and flow into the energy storage assembly 200. In the energy release stage, the gaseous carbon dioxide provided to the connecting pipe 113 by the energy release assembly 400 can enter the gas distribution pipe 112, and then enter the gas storage space 111a of the gas storage reservoir 111 through the gas ports 117. The connection position a between the gas distribution pipe 112 and the connecting pipe 113 is arranged close to the middle of the gas distribution pipe 112, so the air resistance of the parts of the gas distribution pipe 112 located on both sides of the connection position a is substantially the same. In the energy storage stage, this is conducive to the roughly consistent air intake flow rate of each air port 117, which is conducive to making the inner membrane sedimentation speed of the air storage reservoir 111 more uniform, avoiding excessive differences in the sedimentation degree of the inner membrane of the air storage reservoir 111 at different positions. In the energy release stage, this is conducive to the roughly consistent air outlet flow rate of each air port 117, which is conducive to making the inner membrane lifting speed of the air storage reservoir 111 more uniform, avoiding excessive differences in the lifting degree of the inner membrane of the air storage reservoir 111 at different positions.

[0065] In some embodiments of the present disclosure, the gas distribution pipe 112 and the connecting pipe 113 may be connected by a tee or a four-way connection.

[0066] In some embodiments of the present disclosure, the distance between the connection position a between the air distribution pipe 112 and the connecting pipe 113 and one end of the air distribution pipe 112 is 45% to 50% of the length of the air distribution pipe 112, and in particular, can be 48% to 50%. In one example, the distance between the connection position a between the air distribution pipe 112 and the connecting pipe 113 and one end of the air distribution pipe 112 is 50% of the length of the air distribution pipe 112. In other words, the midpoint of the air distribution pipe 112 is connected to the connecting pipe 113. In this way, the air resistance of the two parts of the air distribution pipe 112 on both sides of the connection position a can be made as close as possible, which is beneficial to the engineering design and commissioning of the gas storage assembly 110, reduces the complexity of the operation of the gas storage assembly 110, and achieves the effect of reducing the design and operation costs of the gas storage assembly 110.

[0067] In one embodiment of the present disclosure, see Figure 4 to Figure 12 , the gas distribution pipe 112 may be within the range of the gas storage reservoir 111. Specifically, the orthographic projection of the gas distribution pipe 112 on the horizontal plane may be located within the orthographic projection of the gas storage reservoir 111 on the horizontal plane. In this way, the normal gas supply or air intake of the gas distribution pipe 112 to the gas storage space 111a of the gas storage reservoir 111 can be ensured, and the engineering cost caused by the unnecessary extension of the gas distribution pipe 112 can be avoided.

[0068] In one embodiment of the present disclosure, see Fig.13 , the gas distribution pipe 112 can be located below the gas storage reservoir 111, for example, the gas distribution pipe 112 can be buried below the gas storage reservoir 111. The lower end of the gas port 117 is connected to the gas distribution pipe 112, and the upper end passes through the ground membrane of the gas storage reservoir 111 and extends into the gas storage space 111a of the gas storage reservoir 111. In one example, the gas port can be a riser, the lower end of which is connected to the gas distribution pipe 112, and the upper end of which extends into the gas storage space. On the one hand, the main structure of the gas distribution pipe 112 and the gas port 117 (i.e., the main part of the riser) is located below the gas storage reservoir 111, for example, buried below the ground membrane of the gas storage reservoir 111, which is conducive to the fastening and shock absorption of the gas distribution pipe 112 and the gas port 117. On the other hand, this can reduce the support and fixation of the gas distribution pipe 112 in the gas storage space 111a of the gas storage reservoir 111, which is conducive to improving the air tightness of the gas storage reservoir 111. Furthermore, the portion of the connecting pipe 113 within the gas storage reservoir 111 may also be disposed below the gas storage reservoir 111 , for example, at the same level as the gas distribution pipe 112 .

[0069] In one embodiment of the present disclosure, see Figure 4~Figure 9 , the extension direction of the gas distribution pipe 112 is parallel to the length direction of the gas storage reservoir 111. Especially when the length of the gas storage reservoir 111 is much greater than the width of the gas storage reservoir 111, for example, when the length of the gas storage reservoir 111 is greater than twice the width of the gas storage reservoir 111, this can reduce the number of gas distribution pipes 112 within the gas storage reservoir 111, and further reduce the number of connection points between the gas distribution pipe 112 and the connecting pipe 113, which is conducive to reducing construction costs.

[0070] Of course, in some other embodiments of the present disclosure, the extension direction of the gas distribution pipe 112 may also be non-parallel to the length direction of the gas storage reservoir 111. Fig.11 and Fig.12 In the illustrated gas storage assembly 110 , the extension direction of the gas distribution pipe 112 may be perpendicular to the length direction of the gas storage 111 .

[0071] In one embodiment of the present disclosure, see Figure 4~Figure 7 , Figure 9~Figure 12 The number of the gas distribution pipes 112 of the gas storage assembly 110 is multiple, and the multiple gas distribution pipes 112 are arranged at equal intervals. In particular, the gas distribution pipes 112 can be parallel to two opposite edges of the gas storage 111, and one edge of the gas storage 111, each gas distribution pipe 112 and the other edge of the gas storage 111 are arranged side by side at equal intervals. For example, Figure 4~Figure 7In the example, the extension direction of the gas distribution pipe 112 is parallel to the long side edge of the gas storage reservoir 111; one long side edge of the gas storage reservoir 111, a plurality of the gas distribution pipes 112 and another long side edge of the gas storage reservoir 111 are arranged side by side at equal intervals. This arrangement of the gas distribution pipes 112 in the gas storage reservoir assembly 110 can make the gas distribution pipes 112 as evenly distributed as possible in the gas storage reservoir 111, thereby facilitating the uniformity of the gas flow of the inlet or outlet at different positions of the gas storage reservoir 111.

[0072] In some other embodiments of the present disclosure, the gas distribution pipes 112 of the gas storage assembly 110 are parallel to each other and are arranged at equal intervals. The gas storage 111 has a characteristic edge parallel to the gas distribution pipes 112, such as Fig. 9 The long side edge of the gas storage reservoir 111 in the figure is the characteristic edge of the gas storage reservoir 111. In these embodiments, the component of the distance between the characteristic edge of the gas storage reservoir 111 and the nearest gas distribution pipe 112 in the horizontal plane is smaller than the distance between two adjacent gas distribution pipes 112 in the horizontal plane. Fig.10 As shown, the distance between two adjacent gas distribution pipes 112 on the horizontal plane is X, and the component of the distance between the characteristic edge of the gas storage reservoir 111 and the nearest gas distribution pipe 112 on the horizontal plane is Y, satisfying X / 2<Y<X. In particular, the component of the distance between the characteristic edge of the gas storage reservoir 111 and the nearest gas distribution pipe 112 on the horizontal plane is 0.6 times to 0.75 times, for example, 0.66 times, of the distance between two adjacent gas distribution pipes 112 on the horizontal plane. Affected by the inner membrane and outer membrane structure of the gas storage reservoir 111, when the gas storage space 111a of the gas storage reservoir 111 is filled with gaseous carbon dioxide, its height near the edge of the gas storage reservoir 111 is less than that near the middle position; therefore, near the characteristic edge of the gas storage reservoir 111, the area affected by the single gas port 117 when inletting or outleting can be larger on the horizontal plane, which is more conducive to keeping the inner membrane of the gas storage reservoir 111 to settle or rise synchronously. In one example, the characteristic edge of the gas storage reservoir 111 is a long side edge of the gas storage reservoir 111 .

[0073] In one embodiment of the present disclosure, among the multiple air ports 117 provided on the same air distribution pipe 112, at least two adjacent air ports 117 have different opening sizes. On the one hand, the farther the distance between the air port 117 and the connection position a (the connection position between the air distribution pipe 112 and the connection pipe 113), the greater the air resistance between the air port 117 and the connection position a; therefore, the air intake flow rate or the air outlet flow rate of the air port 117 can be adjusted by adjusting the opening size of the air port 117, so that the air intake flow rate or the air outlet flow rate of each air port 117 can be substantially consistent. For example, when the distance between the air port 117 and the connection position a is farther, the opening size of the air port 117 can be larger.

[0074] In some other embodiments of the present disclosure, the opening sizes of the air ports 117 connected to the air distribution pipe 112 can be consistent, and the distance between two adjacent air ports 117 can be adjusted as needed. For example, along the direction from the connection position a to the end of the air distribution pipe 112, the setting interval of the air ports 117 gradually decreases. In other words, the farther the average distance between two adjacent air ports 117 and the connection position a, the smaller the interval between the two adjacent air ports 117. In this way, the air distribution pipe 112 can offset the increase in air resistance at the end of the air distribution pipe 112 by increasing the setting density of the air ports 117, thereby maintaining a rough balance in the total air intake flow rate or the total air outlet flow rate in different areas of the air storage space 111a of the gas storage reservoir 111.

[0075] In one embodiment of the present disclosure, see Figure 4 to Figure 12 The gas storage reservoir assembly 110 has a connecting pipe 113, one end of which is connected to the gas distribution pipe 112, and the other end extends out of the range of the gas storage reservoir 111 so as to be connected to the pipeline structure 120, the energy storage assembly 200 or the energy release assembly 400. Optionally, the portion of the connecting pipe 113 connected to the gas distribution pipe 112 has an extension direction that is perpendicular to the extension direction of the gas distribution pipe 112. With this arrangement, the length of the connecting pipe 113 can be reduced to reduce the cost of the gas storage reservoir assembly 110 while keeping the basic shape of the connecting pipe 113 unchanged. In particular, when there are multiple gas distribution pipes 112 in the gas storage reservoir assembly 110, the connecting pipe 113 minimizes the length of the portion where the gas distribution pipes 112 are connected.

[0076] Optionally, in the gas storage assembly 110, there are multiple gas distribution pipes 112. The connecting pipe 113 includes a first connecting pipe 1131 and a second connecting pipe 1132; the first connecting pipe 1131 is connected to each of the gas distribution pipes 112; one end of the second connecting pipe 1132 is connected to the first connecting pipe 1131, and the other end extends outside the gas storage 111.

[0077] In one embodiment of the present disclosure, the extension direction of the first connecting tube 1131 is perpendicular to the extension direction of the air distribution tube 112; the connection position between the first connecting tube 1131 and the second connecting tube 1132 is 40% to 60% of the length of the first connecting tube 1131 at a distance from one end of the first connecting tube 1131, and the extension direction of the second connecting tube 1132 is perpendicular to the extension direction of the first connecting tube 1131.

[0078] For example, in Figure 4In the example gas storage assembly 110, there are two gas distribution pipes 112, and the extension direction of the two gas distribution pipes 112 is parallel to the length direction of the gas storage 111. The connecting pipe 113 includes a first connecting pipe 1131 and a second connecting pipe 1132. The two ends of the first connecting pipe 1131 are respectively connected to the two gas distribution pipes 112, and the extension direction of the first connecting pipe 1131 is perpendicular to the extension direction of the gas distribution pipes 112. One end of the second connecting pipe 1132 is connected to the middle of the first connecting pipe 1131 (the connection position of the second connecting pipe 1132 and the first connecting pipe 1131 is at Figure 4 (marked as b in the figure), the second connecting pipe 1132 extends beyond the range of the gas storage reservoir 111; for example, the second connecting pipe 1132 extends straightly to the outside of the range of the gas storage reservoir 111 in a direction parallel to the extension direction of the gas distribution pipe 112. Further, the distance between the connection position b and one end of the first connecting pipe 1131 is half the length of the first connecting pipe 1131. In this way, the second connecting pipe 1132 can evenly inflate the two gas distribution pipes 112 or evenly inhale air from the two gas distribution pipes 112 through the first connecting pipe 1131.

[0079] exist Figure 4 In the illustrated gas storage assembly 110, the second connecting pipe 1132 extends from the short side edge of the gas storage 111 outside the range of the gas storage 111, for example, the second connecting pipe 1132 is at the same distance from the two long side edges of the gas storage 111. It is understandable that the configuration of the second connecting pipe 1132 in the embodiment of the present disclosure is not limited thereto.

[0080] In another embodiment of the present disclosure, the extension direction of the first connecting pipe 1131 is perpendicular to the extension direction of the air distribution pipe 112; one end of the second connecting pipe 1132 is connected to one end of the first connecting pipe 1131, and part or all of the extension direction of the second connecting pipe 1132 is parallel to the extension direction of the first connecting pipe 1131.

[0081] For example, in Figure 5 In the illustrated gas storage assembly 110, the second connecting pipe 1132 may first extend to the outside of the gas storage 111 in a direction parallel to the first connecting pipe 1131, and then bend to a suitable position. For example, the extension direction of the gas distribution pipe 112 is parallel to the long side direction of the gas storage 111, the first connecting pipe 1131 extends in a direction perpendicular to the gas distribution pipe 112 and is connected to each gas distribution pipe 112; the first end of the second connecting pipe 1132 is connected to one end of the first connecting pipe 1131, and then extends to the outside of the gas storage 111 in a direction perpendicular to the gas distribution pipe 112, and then bends and extends to a suitable position in a direction parallel to the gas distribution pipe 112.

[0082] For example, in Figure 6In the illustrated gas storage assembly 110, the second connecting pipe 1132 can extend to the outside of the gas storage 111 in a direction parallel to the first connecting pipe 1131. For example, the extension direction of the gas distribution pipe 112 is parallel to the long side direction of the gas storage 111, and the first connecting pipe 1131 extends in a direction perpendicular to the gas distribution pipe 112 and is connected to each gas distribution pipe 112; the first end of the second connecting pipe 1132 is connected to one end of the first connecting pipe 1131, and then extends out of the gas storage 111 in a direction perpendicular to the gas distribution pipe 112. The illustrated solution can make the second connecting pipe 1132 have a shorter length, thereby greatly reducing the cost of the gas storage assembly 110. At the same time, one end of the second connecting pipe 1132 is connected to one end of the first connecting pipe 1131, rather than connecting the second connecting pipe 1132 to the middle of the first connecting pipe 1131, which can reduce the number of connecting joints, thereby further reducing costs.

[0083] exist Figure 4~Figure 6 In the illustrated gas storage assembly 110, the arrangement of the connecting pipe 113 is illustrated by taking the arrangement of two gas distribution pipes 112 in the gas storage assembly 110 as an example. It is to be understood that in the embodiments of the present disclosure, the number of gas distribution pipes 112 in the gas storage assembly 110 is not limited to two. Figure 8 In the illustrated gas storage assembly 110, only one gas distribution pipe 112 may be provided. In this example, the connecting pipe 113 may be directly connected to the gas distribution pipe 112 and extend outside the gas storage 111. Fig. 9 The illustrated gas storage assembly 110 is provided with three gas distribution pipes 112 , and the connecting pipe 113 can be connected to the three gas distribution pipes 112 and extend to outside the gas storage 111 .

[0084] In one embodiment of the present disclosure, see Figure 7 The number of the gas distribution pipes 112 is multiple; the gas storage assembly 110 also includes a balance pipe 118, and the balance pipe 118 is connected to each of the gas distribution pipes 112 (in Figure 7 In the example, position c is used to illustrate the connection position between the air distribution pipe 112 and the balance pipe 118). In other words, the air distribution pipes 112 are connected to each other through the connecting pipe 113 and the balance pipe 118. In this way, within the range of the gas storage reservoir 111, the air paths between the air distribution pipes 112 are in a grid shape through the balance pipe 118 and the connecting pipe 113, which is conducive to the balance of air resistance between different air distribution pipes 112, and further conducive to the balance of air intake flow or air outlet flow in different areas of the gas storage space 111a of the gas storage reservoir 111.

[0085] Optionally, the balancing tubes 118 are arranged in pairs, and each pair of balancing tubes 118 is respectively arranged on both sides of the first connecting tube 1131 and are at the same distance from the first connecting tube 1131. Figure 7 In the example, the gas storage assembly 110 is provided with a pair of balancing pipes 118. Further, the extending direction of the balancing pipe 118 is perpendicular to the extending direction of the gas distribution pipe 112.

[0086] In one embodiment of the present disclosure, see Figure 4 to Figure 12 , a stop valve 116 is provided on the connecting pipe 113. In this embodiment, the stop valve 116 can be opened or closed. When the stop valve 116 is opened, the gas distribution pipe 112 can be connected to the pipeline structure 120, the energy storage component 200 or the energy release component 400 through the connecting pipe 113, so that gaseous carbon dioxide can flow into or out of the gas storage reservoir component 110. When the stop valve 116 is turned off, the connecting pipe 113 can be cut off, so that the gas storage space 111a of the gas storage reservoir 111 is disconnected from the pipeline structure 120, the energy storage component 200 and the energy release component 400. In particular, when the gas storage reservoir component 110 needs maintenance, the gas storage reservoir component 110 can be isolated from the carbon dioxide energy storage system SYS by turning off the stop valve 116, so that the operation of the carbon dioxide energy storage system SYS is not affected during the maintenance of the gas storage reservoir component 110. Optionally, the stop valve 116 is disposed outside the gas storage reservoir 111 to facilitate control and maintenance of the stop valve 116 , thereby further improving the maintainability of the gas storage reservoir assembly 110 .

[0087] In one embodiment of the present disclosure, see Figure 4 to Figure 12 , the connecting pipe 113 is also provided with an exhaust mechanism 114, which can be located between the stop valve 116 and the first end of the connecting pipe 113. That is, in the gas path, the exhaust mechanism 114 is located between the stop valve 116 and the gas distribution pipe 112. The exhaust mechanism 114 can be arranged outside the range of the gas storage reservoir 111. When the exhaust mechanism 114 is opened, the connecting pipe 113 can be directly connected to the outside, for example, to the external air space; at this time, if there is gaseous carbon dioxide in the gas storage space 111a of the gas storage reservoir 111, the gaseous carbon dioxide can be discharged through the exhaust mechanism 114. As an application mode, when the gas storage reservoir assembly 110 needs maintenance, the stop valve 116 can be closed to isolate the gas storage reservoir assembly 110 from the gas path of the carbon dioxide energy storage system SYS, and the exhaust mechanism 114 can be opened to discharge the gaseous carbon dioxide in the gas storage space 111a of the gas storage reservoir 111 or replace the gas in the gas storage space 111a of the gas storage reservoir 111. Optionally, in the normal operating mode of the gas storage assembly 110 , the exhaust mechanism 114 may remain closed.

[0088] In one embodiment of the present disclosure, see Figure 4 to Figure 12 , a flow regulating mechanism 115 may also be provided on the connecting pipe 113, and the flow regulating mechanism 115 may control the flow of gaseous carbon dioxide flowing through the connecting pipe 113. In particular, when the carbon dioxide energy storage system SYS has multiple gas storage reservoir components 110, the inlet flow rate or outlet flow rate of each gas storage reservoir component 110 may be regulated by regulating the flow regulating mechanism 115 of each gas storage reservoir component 110, so that the inlet flow rate or outlet flow rate of each gas storage reservoir component 110 is substantially consistent. Optionally, the flow regulating mechanism 115 may be located outside the range of the gas storage reservoir 111 to facilitate the control and maintenance of the flow regulating mechanism 115.

[0089] In one example, the flow regulating mechanism 115 may be a flow regulating valve, such as a shutter valve.

[0090] In some other examples, the flow regulating mechanism 115 may have a plurality of branch pipes arranged side by side, each of which is provided with a valve. The connecting pipe 113 is divided into two sections at the flow regulating mechanism 115, and one section is connected to the other section by each branch pipe. Among them, the sum of the cross-sectional areas of each branch pipe is not less than the cross-sectional area of ​​the connecting pipe 113. In this way, when the valve on the branch pipe is closed, the branch pipe is turned off; when the valve on the branch pipe is opened, the branch pipe is turned on. The flow of gaseous carbon dioxide flowing through the connecting pipe 113 can be controlled by controlling the number of branch pipes that are turned on. Optionally, the diameter of the branch pipe is 0.4 to 0.5 times the diameter of the connecting pipe 113, and the sum of the cross-sectional areas of each branch pipe is 1.2 to 1.5 times the cross-sectional area of ​​the connecting pipe 113.

[0091] exist Figure 4 to Figure 12 In the example of , the flow regulating mechanism 115 is disposed between the stop valve 116 and the exhaust mechanism 114. It is understood that in other examples of the present disclosure, the flow regulating mechanism 115 may also be disposed at other positions, such as on a side of the exhaust mechanism 114 away from the stop valve 116, or on a side of the stop valve 116 away from the exhaust mechanism 114.

[0092] In one embodiment of the present disclosure, the carbon dioxide energy storage system SYS has a plurality of gas storage reservoir components 110, and the plurality of gas storage reservoir components 110 are all connected to the pipeline structure 120; the energy storage component 200 and the energy release component 400 are all connected to the pipeline structure 120. The pipeline structure 120 can be in a ring network shape, or in a topological shape, or can be a trunk pipeline. In one example, the pipeline structure 120 has an interface corresponding to each gas storage reservoir component 110, and the second end of the gas storage reservoir component 110 is connected to the corresponding interface. Among them, no valve mechanism is provided between two adjacent interfaces. In this way, two adjacent gas storage reservoir components 110 can be connected through the pipeline structure 120. When each gas storage reservoir component 110 is inflated or exhausted, the intake flow rate or the outlet flow rate can be rebalanced between each adjacent gas storage reservoir component 110 with the help of the pipeline structure 120, thereby facilitating the synchronous intake or synchronous outlet of each gas storage reservoir component 110.
