Description

Technical Field

[0001] This invention relates to the field of carbon dioxide capture technology, and more specifically, to a regeneration tower apparatus and a carbon dioxide capture system having the same. Background Technology

[0002] Currently, commonly used CO2 separation methods include absorption, adsorption, and membrane separation. Absorption is the earliest researched, most widely used, and mature CO2 capture method. Absorption involves enriching CO2 by a physical or chemical process between an absorbent and CO2 in an absorption tower. The absorbent is then desorbed in a regeneration tower to obtain CO2 with higher purity, while the absorbent is simultaneously reduced.

[0003] Organic amine absorption is the most widely used chemical absorption method, with a CO2 separation efficiency of approximately 98%. However, since chemical absorption utilizes the reversible chemical reaction of the absorbent, the regeneration of the absorbent requires not only the heat of reaction for the reverse reaction but also high sensible heat of solution and latent heat of vaporization of steam.

[0004] In related technologies, CO2 capture requires a reboiler to provide heat for the reaction of the absorbent, which leads to high energy consumption and increases the cost of CO2 capture. Summary of the Invention

[0005] The main objective of this invention is to provide a regeneration tower device and a carbon dioxide capture system thereon, in order to solve the problem in the related art that the reaction using a reboiler as an absorbent provides heat, resulting in high energy consumption and thus increasing the cost of CO2 capture.

[0006] To achieve the above objectives, according to one aspect of the present invention, a regeneration tower apparatus is provided, comprising: a transparent container having a heat-conducting solution disposed inside; a tower body disposed within the transparent container and surrounded by the heat-conducting solution; a heat-absorbing membrane disposed within the transparent container and located outside the tower body; an air inlet structure passing through the transparent container and communicating with the side wall of the tower body; an air outlet structure passing through the transparent container and communicating with the top of the tower body; a liquid inlet structure passing through the transparent container and communicating with the top of the tower body; and a liquid outlet structure passing through the transparent container and communicating with the bottom of the tower body; wherein the heat-absorbing membrane is capable of heating the heat-conducting solution to heat the tower body.

[0007] Furthermore, the heat-absorbing membrane includes multiple first membrane bodies and second membrane bodies, with the multiple first membrane bodies arranged sequentially along the circumference of the transparent container, and the second membrane body located at the top of the transparent container.

[0008] Furthermore, the regeneration tower device also includes a transmission structure and a drive structure. The transmission structure includes multiple transmission shafts, multiple transmission wheels, and a transmission ring. The first end of each transmission shaft is located inside the transparent container, and the second end of each transmission shaft is located outside the transparent container. A first membrane is provided on each transmission shaft. The multiple transmission shafts and multiple transmission wheels are connected one-to-one. The multiple transmission wheels are located on the outside of the transparent container. The transmission ring is connected to the multiple transmission wheels. The drive structure drives the multiple transmission wheels to rotate through the transmission ring.

[0009] Furthermore, the regeneration tower device also includes a support frame, which is located on the top of the tower body. The transmission ring is rotatably mounted on the support frame. The inside of the transmission ring is provided with a first tooth structure that cooperates with multiple transmission wheels, and the outside of the transmission ring is provided with a second tooth structure that cooperates with the drive structure.

[0010] Furthermore, the regeneration tower device also includes a heating structure and a controller. The heating structure is disposed in the heat-conducting solution, and the controller is electrically connected to both the heating structure and the drive structure.

[0011] Furthermore, the regeneration tower device also includes a temperature sensor, which is placed in the heat-conducting solution, and the controller controls the heating structure and the drive structure based on the temperature sensor.

[0012] Furthermore, the regeneration tower device also includes a telescopic frame, on which the second membrane is mounted, and the telescopic frame can retract to fold the second membrane.

[0013] Furthermore, the first membrane has a wavy structure.

[0014] Furthermore, the transparent container is a cylinder or a cone.

[0015] According to another aspect of the present invention, a carbon dioxide capture system is provided, including a regeneration tower device, wherein the regeneration tower device is the regeneration tower device described above.

[0016] The technical solution of this invention involves a tower body housed within a transparent container, which contains a heat-conducting solution. A heat-absorbing film is disposed inside the transparent container and located on the outside of the tower body. The inlet, outlet, liquid inlet, and outlet structures are all connected to the tower body and extend beyond the transparent container. Through this arrangement, the heat-conducting solution surrounds the outer periphery of the tower body, and the heat-absorbing film is disposed within it. The heat-absorbing film absorbs solar heat and transfers this heat to the heat-conducting solution, thereby raising the temperature of the solution and heating the tower body. This provides heat for the absorbent reaction, eliminating the need for a reboiler and reducing energy waste. Therefore, the technical solution of this application effectively solves the problem in related technologies where a reboiler is used to provide heat for the absorbent reaction, leading to high energy consumption and increased CO2 capture costs.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0029] like Figure 1 , Figure 2 , Figure 4 as well as Figure 5 As shown, in this embodiment, the regeneration tower device includes: a transparent container 10, a tower body 20, a heat-absorbing membrane 30, an air inlet structure 41, an air outlet structure 42, a liquid inlet structure 43, and a liquid outlet structure 44. A heat-conducting solution is disposed inside the transparent container 10. The tower body 20 is disposed inside the transparent container 10 and surrounded by the heat-conducting solution. The heat-absorbing membrane 30 is disposed inside the transparent container 10 and located outside the tower body 20. The air inlet structure 41 passes through the transparent container 10 and communicates with the side wall of the tower body 20. The air outlet structure 42 passes through the transparent container 10 and communicates with the top of the tower body 20. The liquid inlet structure 43 passes through the transparent container 10 and communicates with the top of the tower body 20. The liquid outlet structure 44 passes through the transparent container 10 and communicates with the bottom of the tower body 20. The heat-absorbing membrane 30 can heat the heat-conducting solution to heat the tower body 20.

[0030] In this embodiment, the tower body 20 is housed within a transparent container 10, which contains a heat-conducting solution. A heat-absorbing film 30 is disposed inside the transparent container 10 and located outside the tower body 20. The inlet structure 41, outlet structure 42, liquid inlet structure 43, and liquid outlet structure 44 are all connected to the tower body 20 and extend beyond the transparent container 10. Through this arrangement, the heat-conducting solution surrounds the outer periphery of the tower body 20, and the heat-absorbing film 30 is disposed within it. The heat-absorbing film 30 absorbs solar heat and transfers it to the heat-conducting solution, thereby raising the temperature of the solution and heating the tower body 20. This provides heat for the absorbent reaction, eliminating the need for a reboiler and reducing energy waste. Therefore, this embodiment effectively solves the problem in related technologies where a reboiler is used to provide heat for the absorbent reaction, leading to high energy consumption and increased CO2 capture costs.

[0031] The heat-conducting solution is responsible for absorbing and transferring heat. This solution needs to have good thermal conductivity to efficiently absorb solar energy and transfer it to the tower body 20. The heat-absorbing film 30 is one of the key components; it absorbs solar radiation and converts it into heat energy. This film is usually made of special materials that maximize the absorption of specific wavelengths in the solar spectrum, thereby improving energy conversion efficiency. On a clear day, sunlight shines on the heat-absorbing film 30, which converts solar energy into heat energy, heating the heat-conducting solution. Once the temperature of the heat-conducting solution rises, it transfers heat to the tower body 20 through thermal conduction, thus heating the substances inside the tower body 20.

[0032] Specifically, the above design effectively utilizes solar energy or other heat sources to increase the temperature within the tower body 20, thereby enhancing the efficiency of carbon dioxide capture and regeneration. It is suitable for various industrial sites requiring carbon dioxide capture, such as power plants and chemical plants. In practical applications, this regeneration tower device can significantly reduce the cost of carbon dioxide capture, especially in areas rich in solar energy resources. Utilizing solar energy as a heat source, it can achieve almost zero-cost heating, greatly improving the system's economic and environmental benefits. For example, in large-scale power plants built in solar-rich desert areas, or in chemical production facilities utilizing industrial waste heat, this device can demonstrate its high efficiency and energy-saving advantages, becoming a key technology driving the green transformation of industries.

[0033] like Figure 2 , Figure 3 , Figure 5 as well as Figure 6As shown, in this embodiment, the heat-absorbing film 30 includes multiple first film bodies 31 and second film bodies 32. The multiple first film bodies 31 are arranged sequentially along the circumference of the transparent container 10, and the second film bodies 32 are located at the top of the transparent container 10. This arrangement improves the heat absorption efficiency, thereby ensuring a higher temperature for the heat-conducting solution. Furthermore, this design makes heating more uniform, improves the heat transfer efficiency of the solution, and is suitable for applications requiring large-area uniform heating, such as large-scale carbon dioxide capture systems.

[0034] Specifically, uniform heating is key to improving CO2 capture efficiency, especially when handling large-scale gas flows. The distributed design of the first membrane 31 and the second membrane 32 ensures that the temperature of the heat-conducting solution rises uniformly within the transparent container 10, avoiding localized overheating or cooling. This not only improves heating efficiency but also effectively extends the service life of the equipment. For example, in flue gas treatment systems of large coal-fired power plants, this design can significantly improve CO2 capture rates while reducing system maintenance costs caused by uneven heat source distribution, providing reliable technical support for achieving large-scale CO2 emission reduction.

[0035] like Figure 2 , Figure 3 , Figure 5 as well as Figure 6 As shown, in this embodiment, the regeneration tower device further includes a transmission structure 50 and a drive structure 60. The transmission structure 50 includes multiple transmission shafts 51, multiple transmission wheels 52, and a transmission ring 53. The first end of each transmission shaft 51 is located inside the transparent container 10, and the second end of each transmission shaft 51 is located outside the transparent container 10. A first membrane 31 is disposed on each transmission shaft 51. The multiple transmission shafts 51 and multiple transmission wheels 52 are connected one-to-one. The multiple transmission wheels 52 are all located on the outside of the transparent container 10. The transmission ring 53 is connected to the multiple transmission wheels 52. The drive structure 60 drives the multiple transmission wheels 52 to rotate through the transmission ring 53. The first membrane 31 is connected to the transmission shaft 51. The transmission shaft 51 can rotate, thereby driving the first membrane 31 to rotate, thus ensuring that the first membrane 31 always faces the sun. Furthermore, through the cooperation of the transmission structure 50 and the drive structure 60, the automatic rotation of the heat-absorbing membrane 30 can be realized, further improving the uniformity and efficiency of heating, making it suitable for highly automated industrial application environments.

[0036] It should be noted that the design of the automatically rotating heat-absorbing film 30 not only improves the utilization efficiency of thermal energy, but also simplifies the operation process, reduces the need for manual intervention, and makes the system operation more stable and efficient. This design is particularly suitable for industrial scenarios that require continuous operation and unattended operation, such as the CO2 capture system in a large steel plant or the CO2 regeneration facility supporting a wind power station in a remote area. Through automatic control, it can ensure the stable operation of the system in a complex environment and improve the overall energy utilization efficiency.

[0037] As Figure 2 , Figure 3 , Figure 5 and Figure 6 shown, in this embodiment, the regeneration tower device further includes a support frame 70. The support frame 70 is disposed at the top of the tower body 20. The transmission ring 53 is rotatably disposed on the support frame 70. A first tooth structure 531 that cooperates with a plurality of transmission wheels 52 is disposed inside the transmission ring 53, and a second tooth structure 532 that cooperates with the drive structure 60 is disposed outside the transmission ring 53. The setting of the support frame 70 can support the transmission ring 53, thereby making the position of the transmission ring 53 more stable and the cooperation between the first tooth structure 531 and the transmission wheels 52 more stable. And the design of the support frame 70 and the transmission ring 53 ensures the stability and reliability of the transmission structure 50, and is suitable for occasions that require long-term stable operation, such as a continuously operating carbon dioxide capture system.

[0038] Specifically, the combined design of the support frame 70 and the transmission ring 53 not only enhances the mechanical stability of the transmission structure 50, but also provides an efficient energy transmission path, ensuring that the system can still maintain high efficiency during long-term operation. This design is particularly suitable for industrial facilities that need to operate continuously for 24 hours, such as a chemical plant that continuously emits CO2 or a facility that needs to continuously capture CO2 for biofuel production. By providing a stable and reliable operating environment, this design can ensure the continuous and efficient operation of the CO2 capture system and meet the requirements of industrial large-scale production.

[0039] As Figure 2 and Figure 5 shown, in this embodiment, the regeneration tower device further includes a heating structure 80 and a controller. The heating structure 80 is disposed in the heat-conducting solution, and the controller is electrically connected to both the heating structure 80 and the drive structure 60. The heating structure 80 can heat the heat-conducting solution, and the controller can control the start and stop of the heating structure 80, so that when the sun does not heat the heat-conducting solution, the heating structure 80 can supplement heat. Through the setting of the heating structure 80 and the controller, precise temperature control of the heat-conducting solution can be achieved, which is suitable for occasions that require precise temperature control, such as carbon dioxide capture research in a laboratory environment.

[0040] It is important to note that precise temperature control is an indispensable element in scientific research and experimentation, especially when exploring new materials and technologies for CO2 capture. The combined use of the heating structure 80 and the controller allows for rapid adjustment of the solution temperature according to experimental requirements, providing ideal thermodynamic conditions for the experiment. For example, when studying the performance of novel adsorbents or catalysts in the laboratory, precise temperature control helps scientists better understand their reaction kinetics under different conditions, accelerates the research process, and promotes innovation and development in CO2 capture technology.

[0041] like Figure 2 and Figure 5 As shown, in this embodiment, the regeneration tower device also includes a temperature sensor, which is disposed within the heat-conducting solution. The controller controls the heating structure 80 and the driving structure 60 based on the temperature sensor readings. The temperature sensor can detect the stability of the heat-conducting solution, and the controller can control the heating structure 80 and the driving structure 60 based on the temperature of the heat-conducting solution, thereby maintaining a constant temperature of the heat-conducting solution. Furthermore, the combined use of the temperature sensor and the controller allows the system to automatically adjust the heating power and the rotation speed of the heat-absorbing film 30, ensuring efficient system operation. This makes it suitable for applications requiring automated adjustment, such as carbon dioxide capture systems in intelligent factories.

[0042] Specifically, the intelligent coordination of temperature sensors and controllers enables the system to adaptively adjust heating power and rotation speed based on real-time temperature data, ensuring maximum operational efficiency and energy utilization of the entire system. This design is particularly important for intelligent factories, especially when dealing with complex and variable CO2 emission sources, enabling flexible responses to different operating conditions and maintaining optimal system performance. By reducing energy consumption and improving CO2 capture rates, this design helps companies achieve their energy conservation and emission reduction goals while also enhancing the factory's level of intelligence.

[0043] like Figure 1 , Figure 5 as well as Figure 6 As shown, in this embodiment, the regeneration tower device further includes a telescopic frame 90, on which the second membrane 32 is mounted. The telescopic frame 90 can retract to fold the second membrane 32. This configuration enables the second membrane 32 to retract and expand. In other words, the design of the telescopic frame 90 allows the second membrane 32 to be folded as needed, increasing the flexibility of the device and making it suitable for applications requiring regular maintenance and adjustment, such as carbon dioxide capture systems that require regular cleaning.

[0044] Specifically, the design of the telescopic frame 90 not only improves the flexibility of the device but also simplifies the maintenance and cleaning process, allowing the second membrane 32 to be folded and stored when not in use, reducing space occupation and facilitating membrane inspection and cleaning. This design is particularly suitable for CO2 capture systems located in harsh environments, such as offshore wind farms and desert solar power plants. Regular maintenance and cleaning can effectively prevent membrane clogging and efficiency degradation, ensuring the long-term stable operation of the system.

[0045] like Figure 2 , Figure 3 , Figure 5 as well as Figure 6 As shown, in this embodiment, the first membrane 31 has a wavy structure. This design increases the surface area, thereby improving the heat absorption efficiency. Furthermore, the wavy design of the first membrane 31 increases the contact area with the heat-conducting solution, improving heat exchange efficiency and making it suitable for applications requiring high-efficiency heat exchange, such as high-load carbon dioxide capture systems.

[0046] Specifically, the design of the first membrane 31 with a wave-like structure improves heat exchange efficiency by increasing the contact area, which is particularly effective when handling gas flows with high CO2 loads.

[0047] This design can accelerate the temperature rise of the heat transfer solution and shorten the CO2 capture cycle. It is suitable for industrial scenarios with high emissions and high demand, such as large oil refineries and cement plants. By accelerating the heating process, it not only improves the efficiency of CO2 capture but also reduces the energy consumption of the system, helping companies reduce operating costs while meeting environmental regulations.

[0048] like Figures 1 to 6 As shown, in this embodiment, the transparent container 10 is a cylinder or a cone. This design simplifies the overall structure and facilitates installation. The cylindrical or conical transparent container 10 design is not only aesthetically pleasing but also optimizes the flow path of the heat-conducting solution, improving heat transfer efficiency. It is suitable for applications requiring optimized heat transfer paths, such as space-constrained industrial environments.

[0049] Specifically, the cylindrical or conical transparent container 10 design not only enhances the visual appeal of the device but also effectively improves heat transfer efficiency by optimizing the solution flow path. This design is particularly suitable for industrial environments with limited space and compact layouts, such as CO2 capture systems on ships or small-scale CO2 treatment facilities in urban industrial areas. By optimizing the container shape, it enables efficient utilization of thermal energy within limited space while reducing the overall size of the device, facilitating deployment and operation in various confined environments.

[0050] In an embodiment not shown in the figure, the regeneration tower device may also include solar panels to convert collected solar energy into electrical energy. This electrical energy can be stored in batteries for heating on cloudy days or at night. In cases where there is insufficient solar energy, such as on cloudy days or at night, the previously stored electrical energy can be used to heat the heat-conducting solution. This can be achieved through heating structure 80, ensuring that the temperature inside the tower body 20 is maintained at the required level.

[0051] The advantages of the regenerative tower device in this embodiment are that it can utilize free solar energy resources, reducing dependence on traditional energy sources, lowering operating costs, and minimizing environmental impact. Meanwhile, the heating structure 80 serves as a backup solution, ensuring stable system operation under any weather conditions.

[0052] According to another aspect of this application, a carbon dioxide capture system is provided. This embodiment of the carbon dioxide capture system includes a regeneration tower device, which is the regeneration tower device described above. The aforementioned regeneration tower device eliminates the need for a reboiler; the tower body 20 can be heated using a heat-conducting solution to provide heat for the absorbent reaction, thereby reducing energy consumption. Therefore, the technical solution of this application effectively solves the problem in related technologies where providing heat for the absorbent reaction using a reboiler leads to high energy consumption and increases CO2 capture costs.

[0053] By adopting the above-mentioned regeneration tower device, this carbon dioxide capture system can significantly improve its operating efficiency and economy, and has important application benefits for reducing greenhouse gas emissions and achieving green and sustainable development.

[0054] Furthermore, this system boasts advantages such as high flexibility, high automation, and convenient maintenance, making it suitable for various industrial environments, including coal-fired power plants, cement plants, steel mills, and laboratory environments requiring precise control. Through optimized design, the system can adapt to different heat sources, such as solar energy and industrial waste heat, further improving energy utilization efficiency and reducing operating costs. It is an effective tool for achieving green industrial transformation and environmental protection.

[0055] Specifically, the optimized design of the carbon dioxide capture system not only improves capture efficiency and economy but also promotes the green transformation of industry, making a positive contribution to environmental protection. The system can flexibly adapt to various heat sources, maintaining stable operation even under conditions of limited resources or unstable heat sources through automated regulation and efficient heat exchange technology.

[0056] For example, in energy extraction projects in remote areas, geothermal energy can be used as a heat source, or in urban waste treatment facilities, waste heat from waste incineration can be used for CO2 capture. Both methods demonstrate the system's unique environmental and economic benefits. Furthermore, its application in laboratory environments, through precise control of experimental conditions, has accelerated the development of novel CO2 capture technologies.
