Description

Technical Field

[0001] This utility model relates to the field of high-pressure gas storage equipment, and more specifically, to a large-capacity multi-bladder high-pressure gas storage device. Background Technology

[0002] Existing large-capacity high-pressure gas storage systems mostly use single large-capacity gas storage tanks. Based on the pressure they withstand, these tanks can be categorized as high-pressure, medium-pressure, low-pressure, and atmospheric-pressure tanks. Based on the material, they can be classified as carbon steel tanks, carbon fiber wound tanks, fiberglass tanks, low-alloy steel tanks, and stainless steel tanks. When storing large quantities of high-pressure gas, these tanks require increased volume and capacity. Larger tanks are often placed directly on the ground, resulting in a large footprint and placing high demands on the pressure-bearing sidewalls of the tank, requiring strong pressure resistance and thus increasing manufacturing costs. Utility Model Content

[0003] This invention proposes a new large-capacity multi-bladder high-pressure gas storage device to solve one of the aforementioned technical problems.

[0004] In view of this, the present invention proposes a new large-capacity multi-bladder high-pressure gas storage device, comprising at least one set of gas storage components; each set of gas storage components includes a gas transmission system and eight sets of gas storage wells for storing gas; the gas transmission system includes a gas transmission main pipe, an electromagnetic venting valve, and a controller, the controller being connected to the electromagnetic venting valve and the controller; each set of gas storage wells is connected to a gas transmission branch pipe, and at least one set of gas pressure detectors is installed on the inner wall of each set of gas storage wells, each gas pressure detector being connected to the controller, and each gas transmission branch pipe being connected to the gas transmission main pipe.

[0005] In this technical solution, the high-pressure gas storage device consists of at least one gas storage component, and each gas storage component consists of eight gas storage wells and one gas transmission system. Specifically, the eight gas storage wells and one gas transmission system are arranged in a grid shape, so that adjacent gas storage wells can share a portion of the pressure-bearing sidewall. This allows the high-pressure gas to be borne not only by the pressure-bearing sidewall but also by the stored high-pressure gas itself. The entire device can be directly buried underground, reducing the land occupation and lowering manufacturing costs. The controller of the gas transmission system can monitor the internal gas pressure of each gas storage well in real time using a gas pressure detector inside each well, and control the gas transmission in real time through the electromagnetic ventilation valve on the main gas transmission pipe. The gas is then transmitted from the main gas transmission pipe to the branch gas transmission pipe, ensuring the stability of gas transmission and the stability of the high-pressure gas storage device. The overall structure is simple and reasonable.

[0006] Furthermore, each of the gas storage components is semi-buried on the ground surface.

[0007] In this technical solution, a maintenance window can be installed on the exposed portion of each gas storage well to facilitate maintenance.

[0008] Furthermore, the gas transmission system is located in the middle of the eight sets of gas storage wells, and the eight sets of gas storage wells surround the gas transmission system, forming a nine-square grid structure.

[0009] In this technical solution, the nine-square grid structure layout is relatively stable and can effectively prevent unexpected ground movement from affecting the stable storage of high-pressure gas storage devices.

[0010] Furthermore, the gas supply main pipe is equipped with the electromagnetic vent valve.

[0011] In this technical solution, the electromagnetic vent valve is used to control the on / off of gas delivery in the main gas supply pipe under the control of the controller.

[0012] Furthermore, the gas storage chamber inside the gas storage well is used to store gas, and the sidewalls of the gas storage well are made of reinforced concrete.

[0013] In this technical solution, reinforced concrete can be directly cast and molded, its pressure-bearing capacity meets the storage requirements of high-pressure gas, and its production cost is relatively low.

[0014] Furthermore, each of the gas storage wells is cylindrical or hexagonal, the diameter of the main gas transmission pipe is 430 mm, and the volume of the gas storage chamber of each gas storage well is 30,600 cubic meters.

[0015] Compared with the prior art, the advantages of this utility model are:

[0016] (1) Each gas storage component consists of eight gas storage wells and one gas transmission system. Each gas storage well is arranged in close proximity to form a honeycomb structure, so that adjacent gas storage wells can share a portion of the pressure-bearing sidewall. This allows the high-pressure gas to not only be subjected to pressure through the pressure-bearing sidewall, but also to bear part of the pressure through the stored high-pressure gas itself, thus reducing the manufacturing cost of the high-pressure gas storage device.

[0017] (2) Specifically, the eight gas storage wells and one gas transmission system are arranged in a grid shape, which is relatively stable and can effectively avoid the impact of unexpected surface movements on the stable storage of high-pressure gas storage devices. Attached Figure Description

[0024] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0025] The following combination Figures 1 to 5 The utility model will be further described.

[0026] Example 1:

[0027] Reference Figure 1 and Figure 2 As shown, this embodiment provides a large-capacity multi-bladder high-pressure gas storage device, including at least one set of gas storage components 101; each set of gas storage components 101 includes a gas transmission system and eight sets of gas storage wells 102 for storing gas; the gas transmission system includes a gas transmission main 103, an electromagnetic venting valve and a controller (not shown in the figure), the controller being connected to the electromagnetic venting valve and the controller; each set of gas storage wells 102 is connected to a gas transmission branch pipe 104, and at least one set of gas pressure detectors (not shown in the figure) is installed on the inner wall of each set of gas storage wells 102, each gas pressure detector being connected to the controller, and each gas transmission branch pipe 104 being connected to the gas transmission main 103.

[0028] The high-pressure gas storage device of the above embodiment consists of at least one gas storage component 101. Each gas storage component 101 consists of eight gas storage wells 102 and one gas transmission system. Specifically, the eight gas storage wells 102 and one gas transmission system are arranged in a grid shape, so that adjacent gas storage wells 102 can share a portion of the pressure-bearing sidewall. This allows the pressure of the high-pressure gas to be borne not only by the pressure-bearing sidewall, but also by the pressure of the stored high-pressure gas itself. The entire device can be directly buried underground, reducing the land area occupied and lowering the manufacturing cost. The controller of the gas transmission system can monitor the internal gas pressure of each gas storage well 102 in real time based on the gas pressure detector inside each gas storage well 102, and control the gas transmission in real time through the electromagnetic ventilation valve on the gas transmission main 103. The gas is then transmitted to the gas transmission branch pipe 104 through the gas transmission main 103, ensuring the stability of gas transmission and the stability of the high-pressure gas storage device. The overall structure is simple and reasonable.

[0029] Example 2:

[0030] In conjunction with the above embodiments, such as Figure 2 As shown, each group of gas storage components 101 is semi-buried on the ground surface. The gas transmission system is located in the middle of the eight groups of gas storage wells 102. The eight groups of gas storage wells 102 surround the gas transmission system, forming a nine-square grid structure. The gas transmission main pipe 103 is equipped with an electromagnetic vent valve. The gas storage chamber inside each gas storage well 102 is used to store gas. The sidewalls of each gas storage well 102 are made of reinforced concrete. Each gas storage well 102 is cylindrical or hexagonal in shape. Figure 1 and Figure 2 As shown, gas storage well 102 is cylindrical, as... Figure 3 and Figure 4 As shown, gas storage well 102 is a hexagonal columnar shape.

[0031] In the above embodiments, maintenance windows can be provided on the exposed portion of each gas storage well 102 to facilitate maintenance; the nine-grid structure layout is relatively stable and can effectively prevent accidental ground movement from affecting the stable storage of the high-pressure gas storage device; the electromagnetic ventilation valve is used to control the on / off of gas delivery in the main gas delivery pipe 103 under the control of the controller; the reinforced concrete can be directly cast and molded, and the pressure bearing capacity meets the storage requirements of high-pressure gas, with low manufacturing cost.

[0032] In addition, the aforementioned large-capacity multi-bladder high-pressure gas storage device relates to a new high-pressure gas storage method. This method involves excavating pits underground, constructing supports, and then erecting steel frames. Concrete is then poured onto these steel frames to form columnar or cylindrical gas storage wells 102. The arrangement of the gas storage wells 102 is as shown above: eight sets of gas storage wells 102 and one gas transmission system form a grid-like structure. In the gas transmission system, the main gas transmission pipe 103, under the control of a controller, transmits gas to each gas transmission branch pipe 104, which then enters each gas storage well 102. Specifically, the controller can adjust the gas delivery volume of the main gas transmission pipe 103 based on the data displayed by the gas pressure detector in each gas storage well 102.

[0033] In the actual production process, for example, to create a square underground honeycomb shape, the first step is to prepare reinforced concrete materials and prefabricate or cast on-site into square blocks 37 meters long, 37 meters wide, and 34 meters high. Figure 5 As shown, the inner wall thickness is 1.5 meters, the outer wall thickness is 2 meters, the bottom plate thickness is 2 meters, and the dimensions of a single gas storage well 102 are 10 meters * 10 meters * 34 meters. The gas storage volume of each gas storage component 101 is maintained at 30,600 cubic meters. The diameter of the specific gas transmission main pipe 103 is 430 millimeters. If 300,000 cubic meters of gas are to be stored, only ten gas storage components 101 are needed.

[0034] The technical solution of this utility model has been described in detail above with reference to the accompanying drawings. This utility model proposes a large-capacity multi-bladder high-pressure gas storage device. Each gas storage component consists of eight gas storage wells and one gas transmission system. The gas storage wells are arranged adjacent to each other in a honeycomb pattern, allowing adjacent gas storage wells to share a portion of the pressure-bearing sidewall. This means that the pressure of the high-pressure gas is not only borne by the pressure-bearing sidewall, but also by the pressure of the stored high-pressure gas itself, reducing the manufacturing cost of the high-pressure gas storage device. Specifically, the eight gas storage wells and one gas transmission system are arranged in a grid shape, which is relatively stable and can effectively avoid the impact of unexpected ground movement on the stable storage of the high-pressure gas storage device, facilitating production and widespread use.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
