DETAILED DESCRIPTION

[0047] The present invention will be further described below with reference to specific examples. It should be understood that these examples are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

[0050] Unless otherwise specified, all technical features and optional technical features of the present invention can be combined with each other to form a new technical solution.

[0051] Unless otherwise specified, all steps of the present invention may be performed sequentially or randomly, preferably sequentially. For example, the method includes steps (a) and (b), which means that the method may include steps (a) and (b) performed sequentially, or may include steps (b) and (a) performed sequentially. For example, the method may further include step (c), which means that step (c) may be added to the method in any order, for example, the method may include steps (a), (b) and (c), or may include steps (a), (c) and (b), or may include steps (c), (a) and (b), etc.

[0052] Unless otherwise specified, the terms "include" and "comprising" used in the present invention may be open-ended or closed-ended. For example, "include" and "comprising" may mean that other components not listed may also be included or that only the listed components are included.

[0053] First, the nouns appearing in the present invention are explained:

[0054] Internet Data Center (IDC): An IDC is a facility specifically designed to host and manage internet infrastructure. It provides services such as server hosting, network access, and storage space to businesses, governments, and individuals. It is the foundation for the secure operation of e-commerce and other online services.

[0055] Liquid-cooled data center: A data center that uses liquid instead of air as a refrigerant to cool computing equipment.

[0056] UPS (Uninterruptible Power Supply): A device that provides continuous power to equipment during power outages or power instability. It is widely used in computers, communications equipment, medical equipment, and other fields to ensure that important equipment can continue to operate normally during power failures.

[0057] Computing equipment in a data center, such as a computer room, usually consists of multiple computing devices that generate a large amount of heat when operating with electricity. If the heat continues to accumulate, it will have an adverse effect on the data center, causing damage to circuit components and devices in the data center. Therefore, during normal operation of the data center, the data center needs to be cooled. The existing cooling method mainly uses a cold distribution unit to circulate a circulating fluid with a lower temperature to the data center to cool it down, and the circulating fluid needs to be continuously cooled in the cold distribution unit. If solar energy, wind energy, etc. are simply used directly, it is impossible to continuously and stably provide electricity to the data center, and it is impossible to eliminate the carbon footprint, and it is impossible to achieve energy recycling and reduce energy consumption.

[0058] Based on this, the present invention provides an air carbon capture system based on a data center; the technical solution of the present invention is as follows:

[0059] In some embodiments of the present invention, an air carbon capture system based on a data center is provided, comprising: a carbon dioxide capture device 100, the carbon dioxide capture device 100 comprising an absorber 110 and a regeneration electrolyzer 120 connected to each other; the regeneration electrolyzer 120 is provided with a first gas outlet and a second gas outlet, and the outlet of the regeneration electrolyzer 120 is connected to the inlet of the absorber 110.

[0060] refer to Figure 1The carbon dioxide capture device 100 is mainly used to capture carbon dioxide from the air and produce hydrogen. The hydrogen can be converted into electrical energy and used as backup power to supply the data center and the carbon dioxide capture device 100. At the same time, it can also cool the circulating fluid used to cool the data center 400, thereby ensuring that the data center 400 can operate normally. The carbon dioxide capture device 100 includes an absorber 110 and a regeneration electrolyzer 120 that are interconnected. The absorber 110 is used to capture carbon dioxide from the air. For example, the absorber 110 contains a chemical solution for absorbing carbon dioxide. When air passes through the absorber 110, the chemical solution can absorb carbon dioxide and discharge the remaining air out of the absorber 110. At the same time, the air absorbs the heat in the solution to cool the solution. This can effectively reduce the cooling energy consumption of the data center and achieve green and low-carbon goals.

[0061] In some preferred embodiments, absorber 110 can be an empty tower, a packed tower, or a bubble tower. An absorbent, such as an alkaline solution such as potassium hydroxide or sodium hydroxide, is added to absorber 110. The absorbent absorbs carbon dioxide from the air to form carbonates. The air that has absorbed carbon dioxide is discharged from absorber 110 and can cool the electrolytic solution. Multiple inlets can be provided in absorber 110, such as an absorbent inlet or an electrolyte inlet, each connected to different devices and equipment.

[0062] The regeneration electrolyzer 120 obtains an electrolytic solution from the absorber 110. The electrolytic solution is a solution, such as a carbonate solution, obtained after the absorber 110 absorbs carbon dioxide through an absorbent. This electrolytic solution undergoes electrolysis in the regeneration electrolyzer 120 to produce a mixed gas and hydrogen. The regeneration electrolyzer 120 may also be provided with a first gas outlet for outputting hydrogen and a second gas outlet for outputting the mixed gas. For example, the regeneration electrolyzer 120 utilizes an electrolytic regeneration method powered by electrical energy to regenerate the carbonate-rich electrolytic solution from the absorber 110 into an alkaline solution in the cathode chamber. The carbonate-rich electrolytic solution is then fed into the anode chamber of the regeneration electrolyzer 120, where hydrogen and a mixed gas are generated, respectively. The regeneration electrolyzer 120 can also transfer the regenerated alkaline solution to the absorber 110 for use as an absorbent. The mixed gas can be separated to obtain carbon dioxide, which can be stored or used for other purposes, significantly achieving zero carbon emissions.

[0063] In some preferred embodiments, the absorber 110 may include a shell; a filler is provided in the shell, and the filler is used to react the air flowing into the shell with the absorbent to absorb CO2 in the air to generate an electrolytic solution.

[0064] refer to Figure 1The absorber 110 includes a shell with a storage space inside. A filler is provided in the storage space. Air can be transported into the storage space through a blower and other equipment. The filler is sprayed with an absorbent. When the air is transported into the shell, the carbon dioxide in the air reacts fully with the absorbent, and the air after desorbing the carbon dioxide is transported to the outside of the shell; the electrolytic solution generated by the absorbent absorbing the carbon dioxide can be temporarily stored in the shell and will be further transported to the regeneration electrolytic cell 120 and the cold distribution device 410 later.

[0065] The provided filler can enable carbon dioxide and the absorbent to react more fully, and the air can fully absorb the heat of the electrolytic solution to cool the electrolytic solution.

[0066] In some preferred embodiments, the absorber 110 may further include a spray piece arranged at the top end of the shell; an inlet A and an inlet B are respectively provided on the shell, and the inlet A and the inlet B are respectively connected to the spray piece; the inlet A is also connected to the cathode chamber of the regeneration electrolytic cell 120, and the inlet B is connected to the cold distribution device 410. The spray piece splashes the solution in the regeneration electrolytic cell 120 and the electrolytic solution that has exchanged heat in the cold distribution device 410 onto the filler piece and reacts with the CO2 in the air flowing into the shell.

[0067] refer to Figure 1 , a spray piece can also be provided in the absorber 110, and an inlet A and an inlet B are respectively provided on the shell, and the inlet A and the inlet B are respectively connected to the spray piece, the inlet A is connected to the cathode chamber of the regeneration electrolytic cell 120, and the inlet B is connected to the cold distribution device 410; the spray piece can spray the absorbent from the top of the shell, so that the contact area between the absorbent and the air is increased, so that the carbon dioxide and the absorbent can react more fully and the air can fully cool the electrolytic solution; the electrolytic solution obtained after the reaction is transported to the cold distribution device 410 to exchange heat with the circulating fluid, and the electrolytic solution with increased temperature is output from the cold distribution device 410, and the pH value drops below the specified value. After it is input into the regeneration electrolytic cell 120 for electrolysis, before the pH value drops below the specified value, it is transported to the spray piece through the inlet B for splashing. Because the electrolytic solution contains incompletely reacted or unreacted absorbent, it is input into the spray piece through the cold distribution device 410 and the inlet B for splashing, which can react with carbon dioxide, thereby improving the utilization efficiency of the absorbent and effectively reducing the raw material cost. The absorbent solution obtained after electrolysis in the regeneration electrolytic cell 120 is input into the spraying part through the inlet A and can be used as an absorbent to absorb carbon dioxide in the air.

[0068] In some preferred embodiments, the absorber 110 may further include a collection tank; the collection tank is arranged at the bottom end of the shell, and the collection tank is used to collect the electrolytic solution after the reaction of the absorbent and CO2; an outlet is also provided on the shell, and the outlet is connected to the collection tank and the cold distribution device 410. The solution in the collection tank flows through the outlet to the cold distribution device 410 and exchanges heat with the circulating fluid in the cold distribution device 410.

[0069] refer to Figure 1 The absorber 110 is also provided with a collecting tank, wherein the collecting tank is provided at the bottom end of the shell for collecting the electrolytic solution after the reaction between the absorbent and CO2; the shell is also provided with an outlet, which is connected to the collecting tank, and the electrolytic solution can be transported to the cold distribution device 410 through the outlet, and then heat exchange can be carried out with the circulating fluid in the cold distribution device 410.

[0070] In some embodiments, the system also includes a hydrogen energy backup power device 300 and a data center 400; the hydrogen energy backup power device 300 includes a hydrogen fuel cell 320, the inlet of the hydrogen fuel cell 320 is connected to the first gas outlet, and the hydrogen fuel cell 320 generates electricity through the electrochemical reaction of hydrogen; the data center 400 includes a cold distribution device 410 and a computing device 420, the cold distribution device 410 is provided with a first inlet, a first outlet, a second inlet and a second outlet, the first inlet is connected to the outlet of the absorber 110, and the second inlet is respectively connected to the inlet of the absorber 110 and the inlet of the regeneration electrolyzer 120; the second inlet is connected to the circulating liquid outlet of the computing device 420, and the second outlet is connected to the circulating liquid inlet of the computing device 420, the cold distribution device 410 exchanges heat from the electrolytic solution in the absorber 110 and the circulating liquid, and cools the computing device 420 through the circulating liquid; the output end of the hydrogen fuel cell 320 is electrically connected to the computing device 420, the absorber 110 and the regeneration electrolyzer 120 respectively.

[0071] refer to Figure 1 The system also includes a hydrogen energy backup power device 300. The hydrogen fuel cell 320 in the hydrogen energy backup power device 300 is connected in series with the regenerative electrolyzer 120 in the carbon dioxide capture device 100. The hydrogen produced by the regenerative electrolyzer 120 can be transported to the hydrogen fuel cell 320 for combustion and power generation. The electrochemical reaction of hydrogen does not produce harmful gases, effectively protecting the air environment. The hydrogen fuel cell 320 is also electrically connected in parallel with the regenerative electrolyzer 120, the absorber 110, and the data center 400. The electricity generated by the hydrogen fuel cell 320 enables the normal operation of the regenerative electrolyzer 120, the absorber 110, and the data center 400.

[0072] In order to protect the components in the data center 400 and avoid damage to the components caused by the heat generated by the operation of the data center 400, a cooling distribution device 410 is provided in the data center 400 and connected to the computing device 420.

It can be first transported to the cold distribution device 410 through the first inlet to exchange heat with the circulating liquid. The electrolytic solution after heat exchange is transported to the regeneration electrolytic cell 120 and the absorber 110 through the first outlet. At this time, the electrolytic solution has a higher temperature. When electrolysis is carried out in the regeneration electrolytic cell 120, the electrolysis efficiency can be improved, and when carbon dioxide is absorbed in the absorber 110, the absorption reaction rate can be increased.

The hydrogen is then compressed by the compressor 150 and input into the hydrogen fuel cell 320 to generate electricity to ensure the operation of the absorber 110, the regeneration electrolytic cell 120 and the data center 400.

[0092] S103 , the solution generated by electrolyzing the electrolytic solution in the regeneration electrolytic cell 120 is transported to the absorber 110 as an absorbent.
