[0038] The typical embodiments embodying the features and advantages of the present application will be described in detail in the following description. It should be understood that the present application can have various changes in different embodiments, which do not deviate from the scope of the present application, and the description and drawings in essence are used for description, not for limiting the present application.

[0039] In the description of the present application, it should be understood that in the embodiments shown in the drawings, the indication of direction or position relationship (such as up, down, left, right, front and back, etc.) is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation. When the position of these elements is changed, the indication of these directions is also changed accordingly.

[0040] In addition, the terms "first", "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0041] Please refer to Figure 1 and Figure 2 It is shown that the low-temperature medium storage tank system 10 of the embodiment of the present application comprises an outer container 100 and a plurality of inner container groups 200 arranged in the outer container 100. Wherein, the outer container 100 can be a straight cylindrical tank structure. The outer container 100 can be arranged vertically, thereby facilitating the saving of floor space. The outer container 100 can be made of carbon steel or low-carbon alloy steel and the like.

[0042] As shown in Figure 1 The top of the outer container 100 can be an arc-shaped head structure. The outer container 100 can be provided with a storage tank foundation 101 for supporting the outer container 100 and the inner container groups 200 therein. Wherein, the storage tank foundation 101 can adopt a reinforced concrete structure to stably support the outer container 100 and the inner container groups 200 therein, thereby improving the pressure-bearing capacity and load resistance of the storage tank system 10.

[0043] As shown in Figure 2 , the outer container 100 is provided with a plurality of inner container groups 200. Each inner container group 200 comprises at least one container body 210, and each container body 210 is used to store cryogenic medium.

[0044] For example, referring to Figure 2 , the outer container 100 can be provided with two inner container groups 200, and each inner container group 200 can comprise five container bodies 210. Among them, the two inner container groups 200 can be used independently. For example, the two inner container groups 200 can be used to store different cryogenic media, and can be used for liquid output or liquid input respectively.

[0045] Alternatively, referring to Figure 3 , the outer container 100 can be provided with three inner container groups 200, one of which can comprise four container bodies 210, and the other two can each comprise three container bodies 210. Among them, the three inner container groups 200 can be used independently. For example, the three inner container groups 200 can be used to store different cryogenic media, and can be used for liquid output or liquid input respectively.

[0046] It should be noted that the container bodies 210 of the same inner container group 200 store the same cryogenic medium. The container bodies 210 of different inner container groups 200 can store different cryogenic media or the same cryogenic medium.

[0047] When the container bodies 210 of different inner container groups 200 store the same cryogenic medium, the same cryogenic medium can be stored in different inner container groups 200 to achieve different process operations of the cryogenic medium. For example, during the use of the storage tank system 10, one inner container group 200 can be used for liquid input, and the other inner container group 200 can be used for liquid output.

[0048] For another example, when two inner container groups 200 store liquefied natural gas (LNG), since LNG is composed of multiple components, liquid stratification will occur when it is stored for a long time, causing gas to boil and roll, and it needs to be inverted to mix. Therefore, when two inner container groups 200 are used to store LNG, the two inner container groups 200 can be inverted with each other without the need for additional connection to other external tanks for inversion.

[0049] Among them, each container body 210 can be made of low-temperature-resistant austenitic stainless steel or strain-hardened steel plate. The temperature range of the cryogenic medium stored in each container body 210 can be -196℃ to -45℃.

[0050] Each container body 210 can be a pressure container. The pressure container can be in a form that maintains the state of the container body 210 storing the liquid, such that the container body 210 does not release gas due to overpressure, avoids continuous discharge of gas, and reduces the loss of the storage medium.

[0051] Referring to Figure 1 In one embodiment, each container body 210 is in a vertical arrangement. The vertical arrangement can be advantageous for saving floor space.

[0052] As Figure 1 shown, the container bodies 210 of the multiple inner container groups 200 can be arranged in parallel and spaced apart from each other. In this way, more container bodies 210 can be arranged in the limited space of the outer container 100. In addition, the spaced apart arrangement of the container bodies 210 can avoid the mutual influence of the storage media stored in different inner container groups 200.

[0053] Each inner container group 200 can include one, two, or more container bodies 210. Preferably, when an inner container group 200 includes two or more container bodies 210, the two or more container bodies 210 can be arranged in parallel and spaced apart from each other.

[0054] In the embodiments of the present application, the volume of a single container body 210 can be 50m 3 ~ 500m 3 . The volume of the entire storage tank system 10 can be 500m 3 ~ 6000m 3 . Each container body 210 in each inner container group 200 can have the same volume. However, the present application is not limited thereto, and each container body 210 in each inner container group 200 can have different volumes under certain conditions.

[0055] Referring to Figure 1 , a sandwich space 300 is formed between the outer container 100 and each container body 210, and the sandwich space 300 is used to fill the thermal insulation material 102. The thermal insulation material 102 can be expanded perlite material, foamed glass material, or polyurethane thermal insulation material, or a mixture of various thermal insulation materials, etc.

[0056] It can be understood that the sandwich space 300 exists between the inner wall of the outer container 100 and the outer wall of each container body 210, and between any two adjacent container bodies 210. The sandwich space 300 filled with the thermal insulation material 102 can play a role of thermal insulation, thereby being advantageous for maintaining the low-temperature state of the container body 210 and being advantageous for prolonging the low-temperature storage life of the container body 210.

[0057] For example, the interlayer space 300 can be connected to an external nitrogen charging system. The external nitrogen charging system is used to charge nitrogen into the interlayer space 300, so that the interlayer space 300 is kept in a positive pressure state, avoiding moisture in the air from entering the interlayer space 300.

[0058] In other embodiments, the interlayer space 300 can also be connected to a vacuum pumping system, which is used to pump the interlayer space 300 to keep the interlayer space 300 in a vacuum state.

[0059] Referring to Figure 2 , Figure 4 and Figure 5 , each content container group 200 is provided with a liquid phase pipeline 220, which communicates with the bottom of each container body 210 of the content container group 200, and is arranged in the interlayer space 300 and extends out of the outer container 100. The liquid phase pipeline 220 of each content container group 200 can include a main pipe and a plurality of branch pipes, one end of the main pipe extends out of the outer container 100, the other end of the main pipe communicates with one end of the plurality of branch pipes respectively, and the other end of the plurality of branch pipes respectively communicates with each container body 210. Through the liquid phase pipeline 220, the liquid inlet and outlet process operations of each container body 210 of each content container group 200 can be realized.

[0060] Each content container group 200 is provided with a gas phase pipeline 230, which communicates with the top of each container body 210 of the content container group 200, and is arranged in the interlayer space 300 and extends out of the outer container 100. The gas phase pipeline 230 of each content container group 200 can include a main pipe and a plurality of branch pipes, one end of the main pipe extends out of the outer container 100, the other end of the main pipe communicates with one end of the plurality of branch pipes respectively, and the other end of the plurality of branch pipes respectively communicates with each container body 210. Through the gas phase pipeline 230, the pressure control and gas discharge process operations of each container body 210 of each content container group 200 can be realized.

[0061] It can be understood that a set of liquid phase pipeline 220 and gas phase pipeline 230 can be provided for each content container group 200, so that each content container group 200 can realize the requirements of liquid inlet, liquid outlet and exhaust respectively.

[0062] It should be noted that each content container group 200 can also include other pipelines, valve components or process ports to meet the use requirements of the storage tank system 10. For example, a pressure gauge, a safety valve and the like can be arranged on the gas phase pipeline 230. For example, a detection port can be provided on any container body 210 of each content container group 200, through which the liquid level of the content container group 200 can be detected. For example, a maintenance port can be provided on each container body 210, through which personnel can enter the container body 210 for maintenance.

[0063] Referring toFigure 1 and Figure 6 In one embodiment, each container body 210 is supported by a plurality of pillars 400 and disposed in the outer container 100. For example, three pillars 400 may be disposed at the bottom of each container body 210, and the three pillars 400 may be arranged in a triangular shape, which can improve the support stability of the container body 210.

[0064] like Figure 6 As shown, the top end of the support 400 is connected to the bottom of the container body 210, and the bottom end of the support 400 is connected to the bottom of the outer container 100. The support 400 is provided with a heat insulation structure 410, which is used to prevent the cold energy of the container body 210 from being transferred to the outer container 100. By providing the heat insulation structure 410, the cold energy loss of the low-temperature medium in the container body 210 can be effectively avoided.

[0065] Specifically, the support 400 includes a first column 420 and a second column 430. The top end of the first column 420 is connected to the bottom of the container body 210, the bottom end of the first column 420 is connected to the top end of the second column 430, and the bottom end of the second column 430 is connected to the bottom of the outer container 100. The thermal insulation structure 410 is disposed between the first column 420 and the second column 430.

[0066] In this embodiment, the support 400 includes a first column 420 and a second column 430, which are separated by an insulation structure 410, which not only facilitates the installation of the insulation structure 410, but also effectively prevents the cold from being transferred downward along the support 400.

[0067] See also Figure 6 In one embodiment, the heat insulation structure 410 includes a first partition 411, a heat insulation layer 412, and a second partition 413. The first partition 411 is fixed to the bottom end of the first column 420, and the second partition 413 is fixed to the top end of the second column 430.

[0068] The first partition plate 411 may be welded to the bottom end of the first column 420. The area of ​​the first partition plate 411 may be larger than the cross-sectional area of ​​the first column 420.

[0069] The second partition plate 413 may be welded to the top of the second column 430. The area of ​​the second partition plate 413 may be larger than the cross-sectional area of ​​the second column 430. The area of ​​the second partition plate 413 may be equal to the area of ​​the first partition plate 411.

[0070] like Figure 6As shown, the thermal insulation layer 412 is sandwiched between the first partition 411 and the second partition 413, and the first partition 411 and the second partition 413 are relatively fixedly connected. The thermal insulation layer 412 may be a thermally insulating fiberglass plate structure. The area of ​​the thermal insulation layer 412 may be greater than or equal to the area of ​​the first partition 411 and the second partition 413. When the thermal insulation layer 412 is sandwiched between the first partition 411 and the second partition 413, the first partition 411 and the second partition 413 are completely isolated by the thermal insulation layer 412, thereby reliably isolating the first column 420 from the second column 430 and preventing the transfer of cold energy between them.

[0071] Preferably, the first partition 411 and the second partition 413 can be detachably fixedly connected. Specifically, the thermal insulation structure 410 includes a fastener 414. The first partition 411 is provided with a first fixing hole, the second partition 413 is provided with a second fixing hole, and the thermal insulation layer 412 is provided with a through hole. The fastener 414 is used to pass through the first fixing hole, the through hole, and the second fixing hole in sequence. The fastener 414 can be a bolt. The fastener 414 is used to connect the first partition 411, the thermal insulation layer 412, and the second partition 413. The structure is simple and can reliably achieve a relatively fixed connection between the first partition 411 and the second partition 413.

[0072] like Figure 6 As shown, in one embodiment, the thermal insulation structure 410 includes multiple thermal insulation washers 415. These washers 415 are respectively mounted on the exterior of the fastener 414 and received in the first and second fixing holes. The thermal insulation washers 415 can isolate heat transfer between the fastener 414 and the first and second partitions 411 and 413. The provision of multiple thermal insulation washers 415 completely isolates the fastener 414 from the first and second partitions 411 and 413, preventing low temperatures on the container body 210 side from being transferred downward through the first partition 411 and fastener 414, and also preventing relatively high temperatures on the outer container 100 side from being transferred upward through the second partition 413 and fastener 414. This further prevents cold energy from the container body 210 from being transferred to the outer container 100, thereby improving the low-temperature storage performance of the container body 210.

[0073] like Figure 6 As shown, in one embodiment, the first column 420 may be a hollow structure. The interior of the first column 420 may be filled with the thermal insulation material 102. This further prevents the cold energy of the container body 210 from being transferred to the outer container 100, thereby improving the low-temperature storage performance of the container body 210.

[0074] It is understood that the second column 430 can also be a hollow structure, which also saves materials and reduces costs. Of course, in other embodiments, the second column 430 can also be a solid structure to help improve the supporting capacity of the pillar 400.

[0075] Referring to Figure 7 In an embodiment of the present application, the low-temperature medium storage tank system 10 further comprises a liquid leakage detection structure 500 arranged on the outer container 100. The liquid leakage detection structure 500 is used to detect the liquid leakage state in the interlayer space 300. By arranging the liquid leakage detection structure 500, the staff can timely find and handle the medium leakage condition, thereby facilitating the protection of the storage tank system 10 and the safety of the staff.

[0076] For example, the liquid leakage detection structure 500 can comprise a temperature sensor 510 arranged on the sidewall of the outer container 100, and the detection end of the temperature sensor 510 extends into the interlayer space 300. When the temperature sensor 510 detects that the temperature in the interlayer space 300 decreases significantly, it can be judged that the container body 210 may have a leakage.

[0077] For example, the liquid leakage detection structure 500 comprises a sampling valve port 520 arranged on the sidewall of the outer container 100 and communicating with the interlayer space 300. When necessary, the gas in the interlayer space 300 can be collected through the sampling valve port 520, so as to analyze the gas composition and determine whether the container body 210 has a leakage.

[0078] For example, the sampling valve port 520 can be provided with a valve capable of being opened and closed. When sampling is needed, the valve is opened; when sampling is not needed, the valve is closed to ensure the sealing of the interlayer space 300.

[0079] In other embodiments, the liquid leakage detection structure 500 can also be a liquid leakage sensor, which is preferably arranged at the bottom of each container body 210 and located in the interlayer space 300, so as to detect in real time whether the container body 210 has a leakage.

[0080] The low-temperature medium storage tank system of the embodiment of the present application comprises an outer container 100 and a plurality of inner container groups 200 arranged in the outer container 100, each inner container group 200 comprising at least one container body 210, and each container body 210 is used to store low-temperature medium. Therefore, the storage tank system can realize the purpose of simultaneously storing two or more kinds of low-temperature medium, or simultaneously performing two process operations.

[0081] For example, the low-temperature medium storage tank system of the embodiment of the present application is applied to a peak shaving station project, and one storage tank system can realize separate process operation of liquid inlet and liquid outlet. For another example, the low-temperature medium storage tank system of the embodiment of the present application is applied to a peak shaving station project, and if long-time storage is required, tank inversion operation can be performed in one storage tank system after a certain period of time to avoid component stratification. For another example, the low-temperature medium storage tank system of the embodiment of the present application is applied to an air separation or liquefaction plant project, and when liquid oxygen and liquid nitrogen need to be stored simultaneously or LNG and liquid ethylene need to be stored simultaneously, one storage tank system can realize the purpose of simultaneously storing liquid oxygen and liquid nitrogen or simultaneously storing LNG and liquid ethylene.

[0082] The low-temperature medium storage tank system of the embodiment of the present application adopts the mode of multiple inner container groups sharing one outer container, the multiple inner container groups can be distributedly arranged, and the multiple inner container groups can realize the effect of parallel use. Thus, it is beneficial to broaden the function and use of the storage tank system, make the use mode of the storage tank system more flexible, and can be beneficial to save project construction land.

[0083] Specifically, the mode of multiple inner container groups sharing one outer container makes the storage tank system use one or some inner container groups for liquid outlet operation and another or some inner container groups for liquid inlet operation. Thus, the inconvenience caused by the need for both liquid inlet and liquid outlet in the same storage tank system is avoided.

[0084] The mode of multiple inner container groups sharing one outer container makes the storage tank system store different media according to the demand, and meets the demand of one storage tank system for storing multiple media.

[0085] It can be understood that although the embodiment of the present application provides a storage tank system with multiple inner container groups arranged in an outer container, each inner container group can be independently used. However, it can be understood by those skilled in the art that in actual production and application process, the multiple inner container groups in the outer container can be connected by pipelines to form a whole storage tank for use, and the specific mode can be determined according to the situation.

[0086] The above embodiments are only exemplary descriptions of structures, and the structures in the embodiments are not fixedly combined structures. In the absence of structural conflicts, the structures in the multiple embodiments can be arbitrarily combined for use.

[0087] While the present application has been described with reference to several exemplary embodiments, it is understood that the words that have been used are words of description and illustration, rather than words of limitation. As mentioned above, the present application is capable of taking many forms of implementation and being practiced in various ways, and the above description is not intended to limit the application in any way, except as required by the appended claims and their equivalents.
