Abstract
Description
Technical Field
[0001] This application relates to the field of carbon capture technology, and in particular to a shipborne carbon capture system and transportation equipment. Background Technology
[0002] As global shipping regulations become increasingly stringent, ships and other vessels on water are required to capture carbon dioxide from their exhaust gases during navigation in order to reduce carbon intensity.
[0003] In existing technologies, carbon capture is performed using a solution absorption method. During ship navigation, exhaust gas is discharged into a separation device. A chemical solution, such as an amine solution, reacts with the carbon dioxide in the exhaust gas, separating the carbon dioxide and collecting it dissolved in the chemical solution. The collected carbon dioxide-containing chemical solution is then transported to a heat exchanger for heating, causing the chemical reaction to proceed in reverse and releasing the carbon dioxide. The released carbon dioxide is then dried, compressed, and stored in a high-pressure storage device mounted on the ship. Upon arrival at port, the compressed and liquefied carbon dioxide is unloaded and transferred to a receiving facility at the port.
[0004] This results in limited flexibility in carbon capture operations. Utility Model Content

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation
[0046] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. In the absence of conflict, the following embodiments and features can be combined with each other.
[0047] In existing technologies, carbon capture is performed using a solution absorption method. During ship navigation, exhaust gas is discharged into a separation device. A chemical solution, such as an amine solution, reacts with the carbon dioxide in the exhaust gas, separating the carbon dioxide and collecting it in the chemical solution. The collected carbon dioxide-containing chemical solution is then transported to a heat exchanger for heating, causing the chemical reaction to proceed in reverse and releasing the carbon dioxide. The released carbon dioxide is then dried, compressed, and stored in a high-pressure storage device mounted on the ship. Upon arrival at port, the compressed and liquefied carbon dioxide is unloaded and transferred to a receiving facility at the port.
[0048] This results in a large number of devices and a complex operating system required for carbon capture operations.
[0049] Furthermore, because existing carbon capture operations require numerous devices with different functions, these devices are difficult to move once installed, thus limiting the amount of carbon dioxide captured. If an increase in carbon capture is needed later, the entire system must be replaced, resulting in high costs.
[0050] Meanwhile, existing shipborne carbon capture systems also require the installation of corresponding high-pressure pipelines and storage equipment at rest stops such as ports in order to unload carbon dioxide from docked ships, which places high demands on the equipment conditions of the rest stops.
[0051] To overcome the deficiencies in the prior art, the shipborne carbon capture system and transportation equipment provided in this application include a first connecting pipe assembly, a second connecting pipe assembly, and at least one solid adsorption carbon capture module. Each solid adsorption carbon capture module corresponds to a carbon dioxide emission reduction of W tons for one standard voyage. The inlet of the solid adsorption carbon capture module is connected to the carbon dioxide emission source through the first connecting pipe assembly, and the outlet is connected to the second connecting pipe assembly. This allows carbon dioxide-containing gas emitted from the carbon dioxide emission source to be input into the solid adsorption carbon capture module through the first connecting pipe assembly, whereby the solid adsorption carbon capture module adsorbs the carbon dioxide in the gas. The remaining gas is then discharged through the outlet, thus achieving carbon dioxide capture. Once the solid adsorption element of a solid adsorption carbon capture module reaches its adsorption limit, the solid adsorption carbon capture module can be directly replaced. Compared to existing technologies that use multiple devices with different functions to process and capture and store carbon dioxide in gas, the shipborne carbon capture system provided in this application can directly adsorb and store carbon dioxide in gas through the solid adsorption element within the solid adsorption carbon capture module. This makes carbon dioxide capture operations simpler, more efficient, and less energy-intensive. The system includes at least one solid adsorption carbon capture module, and the first connecting pipe assembly is detachably connected to it. This allows the shipborne carbon capture system to adaptively adjust the number of solid adsorption carbon capture modules based on the ship's specific emissions, tonnage, voyage, and related emission requirements. This makes the system more flexible, suitable for ships with various emission levels, and allows for modular disassembly and replacement, simplifying operation. Therefore, the shipborne carbon capture system provided in this application reduces the number of devices required for carbon capture operations, simplifying the process.
[0052] The present invention will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the present invention.
[0053] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this application provides a shipborne carbon capture system, including:
[0054] Solid adsorption carbon capture module 100, at least one solid adsorption carbon capture module 100 is provided, and the carbon dioxide emission reduction of any one solid adsorption carbon capture module 100 for one standard flight segment is W tons.
[0055] The solid adsorption carbon capture module 100 is provided with an air inlet 121 and an air outlet 131;
[0056] The first connecting pipe assembly 300 connects the air inlet 121 to the carbon dioxide emission source on the ship;
[0057] The second connecting pipe assembly 400 is connected to the air outlet 131;
[0058] The shipboard carbon capture system is configured to load and activate a corresponding number of solid adsorption carbon capture modules 100, depending on the ship's voyage and / or tonnage.
[0059] First of all, it should be noted that Figure 4 and Figure 5 The dashed arrow indicates the approximate flow direction of the gas within the cavity 111.
[0060] The solid adsorption carbon capture module 100 is modular, and at least one is provided. Each solid adsorption carbon capture module 100 corresponds to a carbon dioxide emission reduction of W tons for one standard voyage. For example, the carbon dioxide emission reduction of each solid adsorption carbon capture module 100 can be 10 tons, 20 tons, or 30 tons, and this application does not limit this. In specific settings, the number of solid adsorption carbon capture modules 100 can be flexibly adjusted according to the actual carbon dioxide treatment requirements to achieve flexible adjustment of the carbon dioxide emission reduction of the entire shipborne carbon capture system. Therefore, for smaller ships, shorter voyages, or lower carbon emission reduction requirements, only one or a small number of solid adsorption carbon capture modules 100 can be used, while for larger ships, longer voyages, or higher carbon emission reduction requirements, multiple solid adsorption carbon capture modules 100 can be added in parallel or series to improve the carbon capture capacity of the entire system.
[0061] An inlet 121 and an outlet 131 are provided on the solid adsorption carbon capture module 100 to ensure that carbon dioxide gas can smoothly enter and exit the solid adsorption carbon capture module 100. The inlet 121 introduces the gas containing carbon dioxide into the receiving cavity 111, so that the gas comes into contact with the solid adsorbent 200 for adsorption; the outlet 131 discharges the gas after adsorption treatment from the module, completing the entire carbon capture process. Specifically, the outlet 131 can be directly connected to the outside to discharge the gas after adsorption treatment directly to the outside, or it can be connected to a pipeline structure and discharged to the outside after being guided by the pipeline structure. This application does not limit this.
[0062] The detachable connection between the first connecting pipe assembly 300 and the solid adsorption carbon capture module 100 allows for easy separation or connection, facilitating flexible adjustment of the number of solid adsorption carbon capture modules 100 as needed. Furthermore, the structure of the first connecting pipe assembly 300 can be flexibly adjusted based on the number and arrangement of the solid adsorption carbon capture modules 100. For example, the first connecting pipe assembly 300 is also detachably connected to and communicates with the exhaust pipe 710 on the ship's hull 700, which serves as the carbon dioxide emission source. The second connecting pipe assembly 400 is detachably connected to the exhaust port 131; the specific assembly / disassembly method can be referenced from that of the first connecting pipe assembly 300.
[0063] Therefore, the shipborne carbon capture system provided in this application includes a first connecting pipe assembly 300, a second connecting pipe assembly 400, and at least one solid adsorption carbon capture module 100. Each solid adsorption carbon capture module 100 corresponds to a carbon dioxide emission reduction of W tons for a standard voyage. The air inlet 121 of the solid adsorption carbon capture module 100 is connected to the carbon dioxide emission source through the first connecting pipe assembly 300, and the air outlet 131 is connected to the second connecting pipe assembly 400. In this way, carbon dioxide-containing gas emitted from the carbon dioxide emission source can be input into the solid adsorption carbon capture module 100 through the first connecting pipe assembly 300, allowing the solid adsorption carbon capture module 100 to adsorb the carbon dioxide in the gas. The remaining gas is then discharged through the air outlet 131, thus achieving carbon dioxide capture. Once the solid adsorption element 200 of a certain solid adsorption carbon capture module 100 reaches its adsorption limit, the solid adsorption carbon capture module 100 can be directly unloaded and replaced to achieve carbon dioxide unloading, eliminating the need to install pipelines and storage equipment at rest stops.
[0064] Compared to existing technologies that use multiple devices with different functions to process gas and capture and store carbon dioxide, the shipborne carbon capture system provided in this application can directly adsorb and store carbon dioxide in gas through the solid adsorption element 200 in the solid adsorption carbon capture module 100, making carbon dioxide capture operations simpler, more efficient, and less energy-intensive.
[0065] The system includes at least one solid adsorption carbon capture module 100, and the first connecting pipe assembly 300 is detachably connected to the solid adsorption carbon capture module 100. This allows the shipborne carbon capture system provided in this embodiment to adaptively adjust the number of solid adsorption carbon capture modules 100 loaded according to the specific emissions of the ship and related emission requirements. This makes the shipborne carbon capture system more flexible in use, suitable for ships with various emission levels, and allows for modular disassembly and replacement, simplifying operation. Therefore, the shipborne carbon capture system provided in this embodiment reduces the number of devices required for carbon capture operations, simplifying the carbon capture process.
[0066] In some embodiments, refer to Figure 4 and Figure 5 As shown, the solid adsorption carbon capture module 100 includes:
[0067] The module housing 110 has a receiving cavity 111 inside, which is filled with a solid adsorbent 200 for adsorbing carbon dioxide.
[0068] The first connector 120 is disposed on the module housing 110 and communicates with the receiving cavity 111. An air inlet 121 is provided on the first connector 120.
[0069] The second connector 130 is disposed on the module housing 110 and communicates with the receiving cavity 111. An air outlet 131 is provided on the second connector 130.
[0070] The solid adsorption carbon capture module 100 has a receiving cavity 111, which provides a stable placement space for the solid adsorbent 200, allowing the solid adsorbent 200 to naturally accumulate or fill the receiving cavity 111. The receiving cavity 111 ensures that carbon dioxide and the solid adsorbent 200 can fully contact each other, so that the solid adsorbent 200 can efficiently adsorb carbon dioxide in the gas introduced into the receiving cavity 111.
[0071] The module housing 110 provides a stable storage and reaction space for the entire solid adsorption carbon capture module 100, protecting the internal solid adsorbent 200 from interference and damage from the external environment, ensuring that the carbon capture process takes place in a relatively stable environment. At the same time, the receiving cavity 111 provides space for filling the solid adsorbent 200, allowing the solid adsorbent 200 to be placed in a concentrated manner, facilitating the flow of carbon dioxide gas within it and ensuring full contact with the solid adsorbent 200, thereby improving adsorption efficiency.
[0072] The first connector 120 provides a connection interface between the module housing 110 and the first connecting pipe assembly 300, facilitating detachable connection, easy installation, disassembly, and maintenance, and can also be flexibly adjusted according to different connection requirements. The air inlet 121 on the first connector 120 serves as a channel for carbon dioxide gas to enter the module housing 110, guiding the gas to flow steadily into the receiving cavity 111.
[0073] Similarly, the second connector 130 provides a connection interface between the module housing 110 and any subsequent gas treatment systems or related pipelines, facilitating the guidance and delivery of the treated gas and ensuring the continuity of the entire carbon capture process. For example, both the first connector 120 and the second connector 130 are tubular structures mounted on the module housing 110, with one end of the tubular structure facing away from the module housing 110 forming an inlet 121 or an outlet 131.
[0074] In specific implementation, refer to Figure 1 , Figure 2 and Figure 3 As shown, multiple solid adsorption carbon capture modules 100 are arranged in an array in a vertical plane, and the air inlet 121 of each solid adsorption carbon capture module 100 is connected to the first connecting pipe assembly 300.
[0075] Vertical array arrangement makes full use of vertical space, which is especially suitable for situations where space is limited on ships. Specifically, the array arrangement involves multiple solid adsorption carbon capture modules 100 stacked in a vertical row and arranged in multiple rows in a horizontal direction. Compared with horizontal arrangement, vertical array arrangement can accommodate more solid adsorption carbon capture modules 100 in a smaller footprint, improving space utilization and enabling the entire carbon capture system to achieve greater processing capacity in a limited space.
[0076] Meanwhile, this regular array arrangement makes the layout of each solid adsorption carbon capture module 100 more neat and orderly, which facilitates the modular design and integration of the entire carbon capture system. This allows the first connecting pipe assembly 300 to be connected to multiple solid adsorption carbon capture modules 100 at the same time, so that the air inlet 121 of each solid adsorption carbon capture module 100 is connected to the first connecting pipe assembly 300, ensuring that the gas containing carbon dioxide is evenly distributed to each solid adsorption carbon capture module 100.
[0077] When the number of solid adsorption carbon capture modules 100 is small, they can be arranged only in the horizontal direction or stacked in the vertical direction. This application does not limit this.
[0078] In some embodiments, refer to Figure 1 and Figure 3 As shown, the first connecting pipe assembly 300 includes:
[0079] First main pipe 310, first main pipe 310 is used to connect to carbon dioxide emission sources;
[0080] Multiple first branch pipes 320 are provided. Each of the multiple first branch pipes 320 is detachably connected to the first main pipe 310. Each of the multiple first branch pipes 320 is connected to a multiple first connector 120 in a one-to-one correspondence. The first main pipe 310 is connected to the air inlet 121 through the first branch pipes 320.
[0081] After the first main pipe 310 is connected to the carbon dioxide emission source, multiple first branch pipes 320 are detachably connected to the first main pipe 310, which can evenly distribute the gas emitted by the emission source to the air inlets 121 of each solid adsorption carbon capture module 100. This ensures that each solid adsorption carbon capture module 100 can obtain a relatively stable and balanced gas flow rate, allowing each module to fully utilize its carbon dioxide adsorption capacity, avoiding the problem of low processing efficiency caused by excessive or insufficient gas in some modules, thereby improving the overall efficiency of the entire carbon capture system.
[0082] Specifically, the first main pipe 310 and multiple first branch pipes 320 are detachably connected. Both the first main pipe 310 and the first branch pipes 320 can use standard pipe fittings, facilitating flexible assembly of the first main pipe 310 and multiple first branch pipes 320 for the solid adsorption carbon capture module 100. For example, the standard pipe fittings are steel fittings capable of withstanding high gas temperatures. Since both the first main pipe 310 and the first branch pipes 320 are standard pipe fittings, the assembly of the first connecting pipe assembly 300 is more convenient, and the first branch pipes 320 and the first connecting member 120 can be quickly disassembled and assembled via a flange structure. Simultaneously, to prevent leakage of the flange structure under high temperature and high pressure exhaust gas conditions, a sealing element can be installed inside the flange structure.
[0083] Furthermore, refer to Figure 1 and Figure 2 The second connecting pipe assembly 400 shown includes:
[0084] Second main pipe 410, the second main pipe 410 is used to communicate with the outside world;
[0085] Multiple second branch pipes 420 are provided. Each of the multiple second branch pipes 420 is detachably connected to the second main pipe 410. Each of the multiple second branch pipes 420 is connected to a multiple second connector 130 in a one-to-one correspondence. The second main pipe 410 is connected to the air inlet 121 through the second branch pipes 420.
[0086] Multiple second branch pipes 420 are connected one-to-one to the second connectors 130 of multiple solid adsorption carbon capture modules 100, which can uniformly collect the gas after adsorption treatment in each module. The collected gas is collected through the second branch pipes 420 and then gathered into the second main pipe 410, and then discharged to the outside or transported to the subsequent treatment stage by the second main pipe 410, making the shipborne carbon capture system more flexible and adaptable.
[0087] Similarly, the second main pipe 410 and the second branch pipe 420 can also use standard pipe fittings, and the second branch pipe 420 is connected to the second connector 130 through a flange structure.
[0088] In specific implementation, refer to Figure 4 and Figure 5 As shown, the module housing 110 has a lifting part 112, which is used to connect with lifting equipment;
[0089] The module box 110 has a limiting part 113. When two adjacent module boxes 110 are stacked one on top of the other, the limiting part 113 of one module box 110 is connected to the other module box 110.
[0090] The hoisting unit 112 provides a clear connection point for hoisting equipment. When installing the solid adsorption carbon capture module 100, the hoisting equipment can connect to the hoisting unit 112 to accurately and stably lift the module housing 110 to the designated position, improving installation efficiency and reducing the workload and difficulty of manual handling. Similarly, when it is necessary to disassemble, repair, or replace the module housing 110, the hoisting unit 112 can be used to conveniently lift it from the installation position for subsequent operations.
[0091] A limiting part 113 is also provided on the module box 110. When two adjacent module boxes 110 are stacked one on top of the other, the limiting part 113 can firmly connect them together, preventing the module boxes 110 from relative displacement or shaking in the vertical direction. This can effectively avoid relative positional changes between the module boxes 110 and ensure the structural stability and safety of the entire shipborne carbon capture system.
[0092] For example, the module housing 110 can be configured as a container. The internal specifications of the container structure are standardized, and the amount of solid adsorption components 200 that it can hold is consistent, as is the amount of carbon dioxide it can adsorb. It also has a lifting section 112 and a limiting section 113. Using a container as the module housing 110 allows direct utilization of existing container manufacturing systems, eliminating the need to design and develop entirely new container manufacturing processes and production lines specifically for the solid adsorption carbon capture module 100, thus reducing manufacturing costs. Simultaneously, containers have standardized dimensions and interfaces, ensuring good compatibility with various transportation tools (such as trucks, trains, and ships). Existing shipping and transportation networks can be used directly for transport without special modifications to the vehicles. This not only reduces transportation costs but also improves transportation efficiency, enabling the rapid and safe transport of the solid adsorption carbon capture module 100 to its destination. For example, each module housing 110 can be configured to hold 10 tons of solid adsorption components 200 capable of adsorbing carbon dioxide.
[0093] The container itself is equipped with lifting rings, which serve as the lifting unit 112 and are highly compatible with common lifting equipment (such as cranes and forklifts). During installation, the lifting equipment can be easily and quickly connected to the lifting unit 112, enabling rapid lifting and installation of the modular container 110, improving installation efficiency and reducing labor and time costs during the installation process.
[0094] Furthermore, the container itself is equipped with limiting parts 113, such as limiting edges, limiting grooves, and limiting posts, which ensure accurate alignment of adjacent containers when stacked or spliced. When installing multiple solid adsorption carbon capture modules 100, the cooperation of the limiting parts 113 ensures accurate relative positions between modules, guarantees tight and sealed connections between modules, avoids gas leakage and other problems caused by installation errors, and improves the stability and reliability of the entire carbon capture system.
[0095] In specific implementation, the solid adsorbent 200 includes at least one of physical adsorption particles and chemical adsorption particles.
[0096] Physical adsorption particles typically possess a large specific surface area and abundant pore structure, enabling them to rapidly adsorb large amounts of carbon dioxide in a short time. This allows the carbon capture process to be completed quickly, improving carbon capture efficiency and making it suitable for scenarios requiring rapid processing of large quantities of carbon dioxide gas. Furthermore, physical adsorption particles primarily adsorb carbon dioxide based on intermolecular van der Waals forces, and this adsorption is reversible. Once the adsorbent reaches saturation, conditions such as temperature and pressure can be changed to desorb the adsorbed carbon dioxide molecules from the adsorbent surface, thus regenerating the adsorbent. This not only reduces operating costs but also allows for the reuse of the adsorbent, improving resource utilization.
[0097] For example, the physical adsorption particles can be at least one of activated carbon particles, molecular sieve particles, metal-organic framework particles and mesoporous silica material particles, and physical adsorption particles with high selectivity for carbon dioxide can be selected.
[0098] Chemisorption particles achieve adsorption by reacting with carbon dioxide to form chemical bonds. This chemical reaction exhibits high selectivity, specifically adsorbing carbon dioxide while adsorbing less of other gases. This allows chemisorption particles to more effectively separate and capture carbon dioxide when treating mixed gases containing multiple gas components, improving the purity of carbon capture. The strong chemical bonds between the chemisorption agent and carbon dioxide result in a higher adsorption capacity. Under the same conditions, chemisorption particles can adsorb more carbon dioxide than physisorption particles, making them suitable for treating gases with low carbon dioxide concentrations or scenarios requiring deep carbon dioxide removal.
[0099] For example, the chemical adsorption particles can be at least one of amine-functionalized particles, calcium-based adsorption particles, and magnesium-based adsorption particles.
[0100] It should also be noted that when physical adsorption particles and chemical adsorption particles are used in combination, the types of physical adsorption particles and chemical adsorption particles should be selected appropriately to avoid mutual interference. For example, activated carbon and amine-functionalized particles should not be mixed to prevent the adsorption process of amine-functionalized particles from damaging the pore structure of activated carbon.
[0101] In addition, since exhaust gas contains not only carbon dioxide, but also water vapor, nitrogen and other gases, when selecting solid adsorbents, particulate materials with strong selective adsorption of carbon dioxide and weak selective adsorption of other gases should be selected.
[0102] Because the adsorption process of the physical adsorption particles (activated carbon, molecular sieves, metal-organic frameworks) and some chemical adsorption particles (amine functionalized particles) is reversible, after the solid adsorption carbon capture module reaches the adsorption limit, desorption or decomposition can be achieved by introducing high-temperature (100℃-150℃) air into the solid adsorption carbon capture module.
[0103] Furthermore, in some embodiments, reference is made to Figure 4 and Figure 5 As shown, the shipborne carbon capture system also includes a dispersion component 500, which is disposed in the receiving cavity 111 and communicates with the air inlet 121. Multiple exhaust ports 510 are provided on the dispersion component 500 at intervals.
[0104] The air inlet 121 is connected to the receiving cavity 111 through the exhaust port 510 on the dispersion member 500.
[0105] When gas enters through the inlet 121, the disperser 500 can disperse the concentrated gas flow into the containment cavity 111 through multiple spaced exhaust ports 510. This avoids excessive concentration of gas in local areas, allowing the gas to contact the solid adsorbent 200 in the containment cavity 111 more evenly, thereby achieving more efficient adsorption and improving the adsorption efficiency of the solid adsorbent 200 for carbon dioxide.
[0106] Meanwhile, the dispersed gas forms a wider flow path within the containment cavity 111, extending the contact time between the gas and the solid adsorbent 200. Simultaneously, multiple exhaust ports 510 disperse the gas into multiple small airflows, increasing the contact area between the gas and the solid adsorbent 200, allowing more carbon dioxide molecules to be captured by the solid adsorbent 200, further enhancing the carbon capture effect.
[0107] For example, the dispersive component 500 can be as follows: Figure 4 As shown, along the bottom of the receiving cavity 111, an air inlet 121 extends towards an air outlet 131, and multiple exhaust ports 510 are spaced apart along the extending direction. An additional exhaust port 510 may also be provided at the end of the dispersing member's extending direction. Alternatively, the dispersing member 500 may be as follows: Figure 5 As shown, the air inlets and outlets are spaced apart along the height of the cavity 111 and located on the side of the cavity 111 that is closer to the inlet 121 and farther from the outlet 131.
[0108] In some embodiments, reference is made to Figure 1 , Figure 2 and Figure 3 As shown, the shipborne carbon capture system also includes a pressure equalization component 600, which is disposed on the first connecting pipe assembly 300 and communicates with the first connecting pipe assembly 300.
[0109] During carbon capture, the gas pressure may fluctuate as it flows through the pipeline. The pressure equalizer 600 can regulate and balance the gas pressure within the first connecting pipe assembly 300, keeping the gas pressure relatively stable. Stable pressure helps the gas flow smoothly within the pipeline, avoiding gas velocity instability caused by sudden pressure changes, thereby ensuring that each solid adsorption carbon capture module can uniformly and stably receive and process the gas.
[0110] For example, the pressure equalizing component 600 can be a buffer tank, a pressure regulating valve, or a pressure stabilizing pump, etc., and the pressure equalizing component 600 can be connected to the first main pipe 310 of the first connecting pipe assembly 300, which is not limited in this application.
[0111] This application also provides a transportation device, including a ship body 700 and a shipborne carbon capture system disposed on the ship body 700.
[0112] The shipborne carbon capture system has been described in the above embodiments and will not be repeated here.
[0113] The transportation equipment provided in this application embodiment includes a shipborne carbon capture system. The shipborne carbon capture system comprises a first connecting pipe assembly 300 and at least one solid adsorption carbon capture module 100. The receiving cavity 111 of the solid adsorption carbon capture module 100 is filled with a solid adsorbent 200 capable of adsorbing carbon dioxide, and the air inlet 121 of the solid adsorption carbon capture module 100 is connected to a carbon dioxide emission source through the first connecting pipe assembly 300. In this way, carbon dioxide-containing gas emitted from the carbon dioxide emission source can be input into the receiving cavity 111 through the first connecting pipe assembly 300, allowing the solid adsorbent 200 to adsorb the carbon dioxide in the gas. The remaining gas is then discharged through the air outlet 131, thus achieving carbon dioxide capture. Once the solid adsorbent 200 of a certain solid adsorption carbon capture module 100 reaches its adsorption limit, the solid adsorption carbon capture module 100 can be directly unloaded and replaced to achieve carbon dioxide unloading.
[0114] Compared to existing technologies that use multiple devices with different functions to process gas and capture and store carbon dioxide, the shipborne carbon capture system provided in this application can directly adsorb and store carbon dioxide in gas through the solid adsorption element 200 in the solid adsorption carbon capture module 100, making carbon dioxide capture operations simpler, more efficient, and less energy-intensive.
[0115] The system includes at least one solid adsorption carbon capture module 100, and the first connecting pipe assembly 300 is detachably connected to the solid adsorption carbon capture module 100. This allows the shipborne carbon capture system provided in this embodiment to adaptively adjust the number of solid adsorption carbon capture modules 100 loaded according to the specific emissions of the ship and related emission requirements. This makes the shipborne carbon capture system more flexible in use, suitable for ships with various emission levels, and allows for modular disassembly and replacement, simplifying operation. Therefore, the shipborne carbon capture system provided in this embodiment reduces the number of devices required for carbon capture operations, simplifying the carbon capture process.
[0116] It should be noted that the terms "one embodiment," "embodiment," "exemplary embodiment," "some embodiments," etc., mentioned in the specification indicate that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same embodiment. Moreover, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments, whether explicitly described or not, is within the knowledge scope of those skilled in the art.
[0117] Generally speaking, terms should be understood at least in part by their use in context.

Similarly, at least in part by context, terms such as "a" or "the" can also be understood to convey either singular or plural usage.
[0118] It should be readily understood that the terms “on,” “above,” and “on top of” in this application should be interpreted in the broadest possible sense, such that “on” means not only “directly on something” but also “on something” with an intermediate feature or layer therebetween, and that “above” or “on top of” means not only “on something” but also “on something” without an intermediate feature or layer therebetween (i.e., directly on something).
[0119] Furthermore, for ease of explanation, spatially relative terms such as "below," "below," "under," "above," and "above" may be used to describe the relationship of one element or feature relative to other elements or features as shown in the figures.
