[0001] The present invention relates to the field of energy technology, and in particular to a distributed data center attached to a natural gas production well station. Background Art

[0002] After the construction of a natural gas well station is completed and the gas production stage begins, the wellhead pressure is often as high as tens or even hundreds of MPa. The gas pressure in the pipeline from the well station to the gas gathering station and purification plant will drop to 6 to 8 MPa. Therefore, technical means are needed to reduce the wellhead pressure to the pressure required by each level of gas pipelines. The huge pressure difference and flow contain extremely abundant, stable and long-lasting energy, which can last for more than 20 years.

[0003] A distributed data center consists of numerous small computer rooms distributed over a certain area, connected by a fiber optic network. This approach primarily addresses the land requirements of centralized data centers and avoids the massive concentration of electricity in a single area. However, operating and maintenance costs are no lower than those of a centralized data center and may even increase due to their dispersed distribution.

[0034] At present, in the relevant technical field, the operating and maintenance costs of setting up distributed data centers in the western natural gas mining areas are relatively high.

[0035] To address this issue, various embodiments of a distributed data center attached to a natural gas production well station are proposed. The distributed data center attached to a natural gas production well station provided by the present invention is configured by attaching the distributed data center to the natural gas production well station. The distributed data center utilizes a pressure differential generator in the distributed data center's power generation bypass to collect pressure differential energy from the gas pipeline during gas transmission operations at the natural gas production well station, providing electrical energy for the operation of the data center's modules. Furthermore, the distributed data center's refrigeration module collects the cooling energy generated by the expansion and pressure reduction of gas after the throttle valve and pressure differential generator during gas transmission operations at the natural gas production well station, providing cooling refrigerant for the operation of the data center's modules. This addresses the technical issues of high operating and maintenance costs associated with installing distributed data centers in western natural gas mining areas.

[0036] This embodiment provides a distributed data center attached to a natural gas production well station. The distributed data center includes a data center module, a main line 15 , a power generation bypass 16 , and a refrigeration module.

[0037] The data center module includes server equipment, refrigeration equipment and a distribution cabinet for powering the server equipment and the refrigeration equipment; the first end of the main line 15 is connected to the gas source 1 of the natural gas production well station, and the second end of the main line 15 is connected to the gas transmission pipeline 6. The main line 15 is provided with a first three-way valve 2, a second three-way valve 4 and a main throttle valve 3 located between the first three-way valve 2 and the second three-way valve 4; the power generation bypass 16 includes a pressure difference generator 5, the first end of the pressure difference generator 16 is connected to the first three-way valve 2, the second end of the pressure difference generator 5 is connected to the second three-way valve 4, and the power output end of the pressure difference generator 5 is connected to the distribution cabinet; the refrigeration module includes a plurality of cold exchange coils arranged on the main line 15 and the power generation bypass 16, and the cold exchange coils are connected to the coils of the refrigeration equipment.

[0038] It should be noted that, in this embodiment, by setting a main line 15 between the gas source 1 of the natural gas production well station and the gas transmission pipeline 6, the first three-way valve 2 and the second three-way valve 4 set on the main line 15 can be used to transfer the pressure difference energy in the gas transmission pipeline to the power generation bypass 16, and the power generation bypass 16 can use the pressure difference energy between the first three-way valve 2 and the second three-way valve 4 to generate power supply energy for the operation of the data center module.

[0039] It is easy to understand that the power generation bypass 16 passes through the pressure difference generator 5. After generating power energy, the power is sent to the distribution cabinet through the pressure difference generator output line 14 at the power output end, and then the distribution cabinet transmits power to the server equipment and refrigeration equipment.

[0040] In this embodiment, the main line 15 is further provided with a diffusion pressure reducing device 8 , a first end of the diffusion pressure reducing device 8 is connected to the gas source 1 , and a second end of the diffusion pressure reducing device 8 is connected to the first three-way valve 2 .

[0041] It is easy to understand that the diffusion and pressure reduction device 8 can adopt a Laval nozzle or a throttle valve device with the same function, so as to achieve throttling and pressure reduction of the gas source 1 of the natural gas production well station.

[0042] On this basis, the cold exchange coil includes a first cold exchange coil 71 arranged in the pipeline between the diffusion and decompression device 8 and the first three-way valve 2, and / or a second cold exchange coil 72 in the pipeline between the pressure difference generator 5 and the second three-way valve 4, and / or a third cold exchange coil 73 in the pipeline between the main throttle valve 3 and the second three-way valve 4.

[0043] like Figure 1 FIG. 1 is a schematic diagram of different configuration schemes of the refrigeration module involved in the embodiment of the present invention. Figure 1 In the implementation scheme in, the cold exchange disk includes a second cold exchange coil 72 arranged in the pipeline between the pressure difference generator 5 and the second three-way valve 4. The second cold exchange coil collects the cold energy generated by the expansion and pressure reduction of the gas in the output pipeline of the pressure difference generator 5 to provide cooling refrigerant for the equipment operation of the data center module.

[0044] like Figure 2 FIG. 1 is a second schematic diagram of different configuration schemes of the refrigeration module involved in the embodiment of the present invention. Figure 2 In the implementation scheme in, the cold exchange disk includes a second cold exchange coil 72 arranged in the pipeline between the pressure difference generator 5 and the second three-way valve 4, and a third cold exchange coil 73 in the pipeline between the main throttle valve 3 and the second three-way valve 4. The second cold exchange coil 72 collects the cold energy generated by the expansion and decompression of the gas in the output pipeline of the pressure difference generator 5 to provide cooling refrigerant for the equipment operation of the data center module. The third cold exchange coil 73 collects the cold energy generated by the expansion and decompression of the gas in the output pipeline of the main throttle valve 3 to provide cooling refrigerant for the equipment operation of the data center module.

[0045] like Figure 3 The figure shows three schematic diagrams of different configuration schemes of the refrigeration module involved in the embodiment of the present invention. Figure 3In the implementation scheme in, the cold exchange plate includes a first cold exchange coil 71 arranged in the pipeline between the diffusion and decompression device 8 and the first three-way valve 2, and a second cold exchange coil 72 in the pipeline between the pressure difference generator 5 and the second three-way valve 4. The first cold exchange coil 71 collects the cold energy generated by the expansion and pressure reduction of the gas in the output pipeline of the diffusion and decompression device 8 to provide cooling refrigerant for the equipment operation of the data center module. The second cold exchange coil 72 collects the cold energy generated by the expansion and pressure reduction of the gas in the output pipeline of the pressure difference generator 5 to provide cooling refrigerant for the equipment operation of the data center module.

[0046] like Figure 4 As shown in FIG, there are four schematic diagrams of different configuration schemes of the refrigeration module involved in the embodiment of the present invention. Figure 3 In the embodiment shown, in this embodiment, the throttle valve device used as the diffusion pressure reduction device is replaced by a Laval nozzle.

[0047] The data center module also includes a refrigeration device, the power input end of the refrigeration device is connected to the power distribution cabinet, and the coil of the refrigeration device is connected to the cold exchange coil through the refrigeration coil input pipe 12 and the refrigeration coil output pipe 13. Figure 5-6 The following are schematic diagrams of two structures of cooling exchange coils.

[0048] It should be noted that a compression pump 11 is also provided on the cooling coil output pipe 13, so that the refrigerant in the cooling coil input pipe 12 and the cooling coil output pipe 13 forms a cycle, thereby exerting a continuous and cyclic cooling effect on the server equipment.

[0049] To more clearly illustrate how refrigeration equipment utilizes the cooling energy generated by the expansion and pressure reduction of gas in the pipeline to cool server equipment, an example is given below to illustrate this.

[0050] According to known information, a standard 40-foot containerized data center unit, for example, includes a power distribution system, cooling and temperature control systems, standard cabinets, and the blade servers housed within them. Within each data center unit, the server cabinets and associated equipment require approximately 250 kilowatts of power, while the cooling equipment requires 150 to 250 kilowatts. Preliminary calculations indicate that the pressure differential and flow rate output by a typical operating natural gas well station, while ensuring safety, can generate hundreds to 1,000 kilowatts of electricity. Based on the cooling capacity of the expander, the cooling capacity generated is 1.5 times the output power. Assuming the output power of the well station's pressure differential power generation system is set at 500 kilowatts, the cooling capacity can reach 750 kilowatts, fully meeting the power and cooling needs of two data center units.

[0051] In addition, in order to ensure good stability of the operating environment of the server equipment in the data center, a backup refrigeration device can also be installed in the data center module. The power input end of the backup refrigeration device is connected to the power distribution cabinet, and uses electricity to drive the cooling source. In this way, even if the well station where the data center is located is shut down for maintenance, the power supply to the data center computer room will not be interrupted, and the backup refrigeration equipment can still exert its cooling efficiency.

[0052] In a preferred embodiment, Figure 1-4 As shown, the power generation module is also provided with an inlet throttle valve 9 and / or an outlet throttle valve 10, the first end of the inlet throttle valve 9 is connected to the first three-way valve 2, the second end of the inlet throttle valve 9 is connected to the pressure difference generator 5, the first end of the outlet throttle valve 10 is connected to the pressure difference generator 5, and the second end of the outlet throttle valve 10 is connected to the second three-way valve 4.

[0053] like Figure 7 As shown, in this embodiment, the main line, power generation bypass and cooling module of the distributed data center can be packaged and defined as Model-A, and the data center module set in the computer room of the distributed data center can be packaged and defined as Model-B.

[0054] like Figure 8 As shown, in this embodiment, a plurality of Model-A and Model-B can be set up in a distributed data center within a certain area to utilize the differential pressure energy of multiple different gas sources or different sections of the same gas source within the area to generate the electrical energy required by the distributed data center.

[0055] Within this area, in order to ensure good reliability of the power supply system of the data center, a grid-connected distribution cabinet 31 can be set up for the distributed data center within this area. The grid-connected distribution cabinet 31 connects the pressure difference generator 5 and the regional power grid 32. The electric energy output by the pressure difference generator 5 is collected into the regional power grid 32 through the grid-connected distribution cabinet 31, and then the regional power grid 32 further distributes the electric energy through the data center power line 33 and the power transformer 34.

[0056] In a preferred embodiment, the server device is provided with an optical fiber interface 21, which can be connected to the external network through a regional optical fiber network 35 or a satellite transceiver 22, thereby realizing data interaction between the server device in the data center and the outside world.

[0057] This embodiment provides a distributed data center attached to a natural gas production well station. By attaching the distributed data center to the natural gas production well station, the pressure difference generator of the power generation bypass in the distributed data center is used to collect the pressure difference energy of the gas pipeline when the natural gas production well station performs gas transmission operations, and provide power for the equipment operation of the data center module. The refrigeration module of the distributed data center is used to collect the cold energy generated by the expansion and pressure reduction of the gas after the throttle valve and the pressure difference generator when the natural gas production well station performs gas transmission operations, and provide cooling refrigerant for the equipment operation of the data center module, thereby solving the technical problem of high operating costs and maintenance costs of setting up distributed data centers in western natural gas mining areas.

[0058] The above are only preferred embodiments of the invention and are not intended to limit the patent scope of the invention. Any equivalent structure or equivalent process transformation made using the contents of the invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the invention.
