Description

Technical Field

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

[0002] The burning of fossil fuels and biomass leads to the continuous accumulation of carbon dioxide in the atmosphere, resulting in a severe greenhouse effect. At the same time, carbon dioxide is widely used in various fields such as food, industry, agriculture, medicine, defense, and commerce, and has potential as a resource. Therefore, capturing carbon dioxide and realizing its resource utilization is urgently needed.

[0003] Currently, carbon dioxide capture mainly involves the recovery and reprocessing of gases such as industrial by-product gases, flue gas, kiln gas, and waste gas. The main carbon dioxide capture processes include solvent absorption, pressure swing absorption, and membrane permeation separation. Solvent absorption has advantages such as high purification efficiency, small equipment footprint, and easy regeneration, and is widely used in industry. Solvent absorption primarily involves the organic amine absorption tower spray method to absorb carbon dioxide; due to different industrial requirements, cylindrical absorption towers with packing materials of varying heights are typically selected.

[0004] In related technologies, catalysts, specifically carbonic anhydrase, are commonly used to improve carbon dioxide capture efficiency. Immobilized carbonic anhydrase is applied to carbon dioxide absorption towers to accelerate the absorption rate. However, immobilized enzymes are generally small particles, and during the reaction, they often flow away with the reaction liquid, eventually entering the high-temperature zone within the tower. This leads to enzyme deactivation and reduces its efficiency. Furthermore, separating the enzyme from the absorption tower packing after the reaction is difficult, increasing operating costs. Summary of the Invention

[0005] The main objective of this invention is to provide a regeneration device and a carbon dioxide capture system thereon, in order to solve the problem in related technologies that immobilized enzymes are easily carried by the reaction liquid to high-temperature areas, which can easily lead to the inactivation of immobilized enzymes.

[0006] To achieve the above objectives, according to one aspect of the present invention, a regeneration apparatus is provided, comprising: a tower body including a first portion and a second portion, the first portion being located below the second portion and having a temperature at the first portion being higher than that at the second portion; an inlet structure communicating with the bottom of the tower body; a barrier structure disposed within the second portion, the barrier structure including a barrier membrane allowing gas to pass through; a circulation pipeline, a first end of which communicates with a side wall of the tower body and is located above the barrier structure, and a second end of which communicates with the top of the tower body; and a pusher structure disposed inside the tower body and located on the barrier membrane, the pusher structure having a driven state and a stopped state; wherein, when the pusher structure is in the driven state, the pusher structure is capable of pushing the catalyst on the barrier membrane into the circulation pipeline.

[0007] Furthermore, the barrier structure also includes a support frame connected inside the tower body, and the barrier membrane is mounted on the support frame.

[0008] Furthermore, the support frame includes a connecting part and a protrusion. The connecting part is connected to the outer periphery of the protrusion. The cross-sectional area of ​​the protrusion gradually increases in the direction from the top of the tower to the bottom of the tower.

[0009] Furthermore, the protrusion is a cone, and the connecting part is a connecting ring. The width 'a' of the connecting ring and the maximum diameter 'b' of the cone satisfy the condition: 0.08 ≤ a / b ≤ 0.25. Furthermore, the connecting part has multiple first hollow areas, and the protrusion has multiple second hollow areas.

[0010] Furthermore, the pushing structure includes a first pushing top and a second pushing top. When the pushing structure is in a stopped state, both the first pushing top and the second pushing top are located on the side of the blocking structure away from the circulation pipeline. When the pushing structure is in a driving state, the first pushing top and the second pushing top can move synchronously towards the side closer to the circulation pipeline.

[0011] Furthermore, the first push top includes a first push plate and a second push plate connected to each other, and the second push top includes a third push plate and a fourth push plate connected to each other. The first push plate and the third push plate are both disposed on the connecting part, and the second push plate and the fourth push plate are both disposed on the protrusion.

[0012] Furthermore, the regeneration device also includes a drive structure that can synchronously drive the first pusher and the second pusher to move.

[0013] Furthermore, the regeneration device also includes a pump body, which is installed on the circulation pipeline.

[0014] According to another aspect of the present invention, a carbon dioxide capture system is provided, including a regeneration device, wherein the regeneration device is the regeneration device described above.

[0015] Applying the technical solution of this invention, the air intake structure is connected to the bottom of the tower body, and the blocking structure is located inside the tower body. The blocking structure includes a blocking membrane that allows gas to pass through. The first end of the circulation pipe is connected to the side wall of the tower body and located above the blocking structure, while the second end of the circulation pipe is connected to the top of the tower body. The pushing structure is located inside the tower body and on the blocking membrane. The pushing structure has a driving state and a stopped state. When the pushing structure is in the driving state, it can push the catalyst on the blocking membrane into the circulation pipe. With the above configuration, flue gas can enter the interior of the tower body through the air intake structure. After entering the interior of the tower body, the flue gas passes through the blocking membrane from below the blocking structure and enters above the blocking structure, i.e., from the first part to the second part. The pushing structure can push the catalyst on the blocking membrane into the circulation pipe and into the interior of the tower body from the second end of the circulation pipe, simultaneously achieving contact with the flue gas for catalysis. When the catalyst falls onto the blocking membrane, it can be pushed again by the pushing structure for collection, thus realizing the recycling of the catalyst and avoiding catalyst waste and failure. Therefore, the technical solution of this application effectively solves the problem in related technologies that immobilized enzymes are easily carried to high-temperature areas by the reaction solution, which can easily lead to the inactivation of immobilized enzymes.

[0027] Carbonic anhydrase is a metalloprotein widely found in living organisms that efficiently catalyzes the hydration and dehydration reactions of carbon dioxide. Immobilized carbonic anhydrase can be used in batches in industrial applications, reducing enzyme usage costs and preventing enzyme contamination of the reaction system. Furthermore, immobilized carbonic anhydrase exhibits structural stability, high temperature resistance, and a long service life.

[0028] Immobilized carbonic anhydrase can accelerate the absorption rate of carbon dioxide in carbon dioxide absorption towers. However, immobilized enzymes are generally small particles, and they often flow away with the reaction liquid during the reaction, reducing their efficiency. Furthermore, it is difficult to separate them from the absorption tower packing after the reaction, increasing operating costs.

[0029] To solve the above-mentioned technical problems, such as Figures 1 to 3 As shown, in this embodiment, the regeneration device includes: a tower body 10, an inlet structure 20, a barrier structure 30, a circulation pipeline 40, and a pusher structure 50. The tower body 10 includes a first part and a second part, with the first part located below the second part. The temperature at the first part is higher than the temperature at the second part. The inlet structure 20 is connected to the bottom of the tower body 10. The barrier structure 30 is disposed within the second part and includes a barrier membrane 31 that allows gas to pass through. The circulation pipeline 40 has a first end connected to the side wall of the tower body 10 and located above the barrier structure 30, and a second end connected to the top of the tower body 10. The pusher structure 50 is disposed inside the tower body 10 and located on the barrier membrane 31. The pusher structure 50 has a driven state and a stopped state. When the pusher structure 50 is in the driven state, it can push the catalyst on the barrier membrane 31 into the circulation pipeline 40.

[0030] Applying the technical solution of this embodiment, the air inlet structure 20 is connected to the bottom of the tower body 10, and the blocking structure 30 is disposed inside the tower body 10. The blocking structure 30 includes a blocking membrane 31, which allows gas to pass through. The first end of the circulation pipe 40 is connected to the side wall of the tower body 10 and located above the blocking structure 30, and the second end of the circulation pipe 40 is connected to the top of the tower body 10. The pusher structure 50 is disposed inside the tower body 10 and located on the blocking membrane 31. The pusher structure 50 has a driving state and a stopping state. When the pusher structure 50 is in the driving state, it can push the catalyst on the blocking membrane 31 into the circulation pipe 40. With the above configuration, the flue gas can enter the interior of the tower body 10 through the air inlet structure 20. After entering the interior of the tower body 10, the flue gas passes through the blocking membrane 31 from below the blocking structure 30 and enters above the blocking structure 30, that is, it enters from the first part to the second part. The pusher structure 50 pushes the catalyst on the barrier membrane 31 into the circulation pipe 40, and then into the interior of the tower body 10 from the second end of the circulation pipe 40, simultaneously achieving catalysis through contact with the flue gas. When the catalyst falls onto the barrier membrane 31, it can be pushed again by the pusher structure 50 for collection, thus achieving catalyst recycling and avoiding catalyst waste and failure. Therefore, the technical solution of this embodiment effectively solves the problem in related technologies where immobilized enzymes are easily carried to high-temperature areas by the reaction liquid, leading to enzyme deactivation. Specifically, this design utilizes the natural temperature gradient from bottom to top within the tower body 10 to effectively improve catalyst regeneration efficiency, especially in the process where the catalyst needs to undergo high-temperature regeneration and low-temperature cooling cycles, significantly shortening the regeneration cycle and reducing energy consumption. It is suitable for various industrial processes requiring catalyst regeneration, such as chemical, petroleum refining, and environmental protection fields, especially in carbon dioxide capture systems, significantly improving system operating efficiency and economy, reducing catalyst loss, and extending system lifespan.

[0031] The temperature mentioned above refers to the operating temperature.

[0032] Specifically, in this embodiment, the catalyst is a mixture of carbonic anhydrase and water, forming a fluid.

[0033] like Figure 1 and Figure 2 As shown, in this embodiment, the tower body 10 includes a first part and a second part, with the first part located below the second part. The temperature at the first part is higher than the temperature at the second part, and the blocking structure 30 is disposed within the second part. This arrangement allows the catalyst to be positioned at a lower temperature, thereby preventing catalyst deactivation.

[0034] like Figures 3 to 5As shown, in this embodiment, the blocking structure 30 further includes a support frame 32, which is connected inside the tower body 10, and the blocking membrane 31 is disposed on the support frame 32. The arrangement of the support frame 32 enables better stability of the position of the blocking membrane 31, that is, the support frame 32 can support the blocking membrane 31.

[0035] It should be noted that the support frame 32 not only stabilizes the barrier membrane 31 but also ensures the uniform distribution of the catalyst within the tower body 10, improving the uniformity and efficiency of the regeneration process and preventing localized overheating or insufficient regeneration caused by catalyst accumulation. It is particularly suitable for large-scale industrial plants requiring catalyst recycling and regeneration, such as flue gas purification systems in power plants and catalytic cracking units in oil refineries, effectively improving regeneration efficiency, reducing energy consumption, and ensuring system operational stability.

[0036] like Figures 3 to 5 As shown, in this embodiment, the support frame 32 includes a connecting portion 321 and a protrusion 322. The connecting portion 321 is connected to the outer periphery of the protrusion 322. The cross-sectional area of ​​the protrusion 322 gradually increases from the top to the bottom of the tower body 10. The protrusion 322 enables flow guidance, allowing the fluid catalyst to flow downwards from the sidewall of the protrusion 322 onto the connecting portion 321. This prevents catalyst from accumulating on the barrier membrane 31, thus ensuring the catalyst can be reused.

[0037] Specifically, this design of the support frame 32 can better adapt to changes in the temperature gradient within the tower body 10, ensuring uniform distribution of the catalyst in different temperature zones, thereby improving regeneration efficiency. Simultaneously, it reduces gas flow resistance and maintains good gas distribution, making it suitable for various regeneration processes with temperature gradients, such as catalyst regeneration in chemical reactors and oil refining units. Especially when treating large, complex industrial waste gases, it can effectively improve catalyst utilization and the overall efficiency of the regeneration system. Figures 3 to 5 As shown, in this embodiment, the protrusion 322 is a cone, and the connecting part 321 is a connecting ring. The width 'a' of the connecting ring and the maximum diameter 'b' of the cone satisfy the condition: 0.08 ≤ a / b ≤ 0.25. This arrangement ensures that the catalyst flows evenly onto the connecting ring. Specifically, a / b = 0.15. Of course, in other embodiments, a / b can also be 0.1, 0.12, 0.18, 0.2, 0.22, or other values.

[0038] The aforementioned proportional design ensures a stable distribution of the catalyst on the support frame 32 without affecting gas flow. This design is suitable for industrial processes requiring catalyst regeneration, such as catalytic cracking regeneration systems in petroleum refining. By precisely controlling the proportions of the support frame 32, excessive catalyst aggregation in the high-temperature zone can be effectively avoided, reducing the risk of catalyst sintering. Simultaneously, sufficient cooling of the catalyst in the low-temperature zone is ensured, improving the safety and efficiency of the regeneration process.

[0039] Specifically, in this embodiment, the connecting ring is provided with a plurality of first hollow areas, and the ratio of the area of ​​the plurality of first hollow areas to the area of ​​the connecting ring is greater than 0.7 and less than 0.9. This ensures the structural strength of the connecting ring on the one hand, and avoids the area that obstructs the flow of flue gas being too large on the other hand.

[0040] Similarly, the protrusion 322 is provided with multiple second hollow areas, which are spaced apart circumferentially along the protrusion. Between two adjacent second hollow areas is a solid portion, which is provided with multiple through holes. The diameter of the through holes gradually increases from the top to the bottom of the protrusion 322. This also ensures the flow of flue gas and maintains the structural strength of the protrusion 322.

[0041] The number of first hollow areas is greater than the number of second hollow areas, and each second hollow area corresponds to one first hollow area.

[0042] Specifically, the perforated area design increases the contact area between the gas and the catalyst, improving regeneration efficiency while reducing the weight of the support frame 32, thus lowering manufacturing costs and energy consumption. This design is suitable for environmental protection equipment requiring catalyst regeneration, such as the catalyst regeneration module in air purifiers. In practical applications, this design significantly improves the catalyst's activity recovery rate and reduces regeneration time. Furthermore, the optimized layout of the perforated area enhances the uniformity of gas flow, further improving the catalyst regeneration effect and the equipment's processing capacity.

[0043] The top of the protrusion 322 is a solid structure.

[0044] like Figures 2 to 4 As shown, in this embodiment, the pusher structure 50 includes a first pusher 51 and a second pusher 52. When the pusher structure 50 is in a stopped state, both the first pusher 51 and the second pusher 52 are located on the side of the blocking structure 30 away from the circulation pipe 40. When the pusher structure 50 is in a driven state, the first pusher 51 and the second pusher 52 can move synchronously towards the side closer to the circulation pipe 40. The first pusher 51 and the second pusher 52 can approach each other and push the catalyst to the first end of the circulation pipe 40.

[0045] It should be noted that this pusher structure 50 effectively propels the catalyst into the circulation pipeline 40, enabling catalyst recycling, reducing static storage time, and preventing catalyst activity loss. It is suitable for industrial equipment requiring catalyst regeneration, such as catalyst regeneration systems in chemical plants. This coordinated motion design ensures the continuity and uniformity of the catalyst during circulation, significantly reducing catalyst consumption, lowering operating costs, and improving system stability and reliability.

[0046] like Figures 2 to 4 As shown, in this embodiment, the first pushing top 51 includes a first pushing plate 511 and a second pushing plate 512 connected to each other, and the second pushing top 52 includes a third pushing plate 521 and a fourth pushing plate 522 connected to each other. The first pushing plate 511 and the third pushing plate 521 are both disposed on the connecting portion 321, and the second pushing plate 512 and the fourth pushing plate 522 are both disposed on the protrusion 322. The structure of the first pushing plate 511, the second pushing plate 512, the third pushing plate 521, and the fourth pushing plate 522 is simple and easy to install. The first pushing plate 511 and the third pushing plate 521 can push and scrape the catalyst on the barrier film 31 located on the connecting portion 321, and the second pushing plate 512 and the fourth pushing plate 522 can push and scrape the catalyst on the barrier film 31 located on the protrusion 322.

[0047] Specifically, the design of this pusher structure 50 can ensure the uniform distribution of the catalyst during the pusher process, reduce mechanical damage to the catalyst during the pusher process, improve regeneration efficiency, and is suitable for industrial processes that require catalyst regeneration, such as catalyst regeneration systems in environmental protection equipment. It can effectively improve the operating efficiency and economy of the equipment, while reducing catalyst loss and environmental pollution.

[0048] Specifically, the first push plate 511 is provided with a first hole, and the third push plate 521 is provided with a second hole. When the first push plate 51 and the second push plate 52 approach each other on the side away from the circulation pipe 40, the catalyst located between the first push plate 51 and the second push plate 52 can pass through the first hole and the second hole. When the first push plate 51 and the second push plate 52 approach each other on the side closer to the circulation pipe 40, the catalyst passing through the first hole and the second hole, as well as the catalyst flowing down from the top of the tower body 10, can be pushed to the circulation pipe 40.

[0049] like Figures 1 to 5As shown, in this embodiment, the regeneration device further includes a drive structure that can synchronously drive the first pusher 51 and the second pusher 52 to move. Specifically, the regeneration device also includes a reset member connected between the first pusher 51 and the second pusher 52, which can pull the first pusher 51 and the second pusher 52 closer to each other on the side away from the circulation pipe 40.

[0050] Specifically, the design of the drive structure can ensure the synchronization and stability of the top pushing process, avoid uneven distribution of the catalyst during the top pushing process, improve the controllability and efficiency of the regeneration process, and is suitable for industrial equipment that requires catalyst regeneration, such as catalyst regeneration systems of large chemical reactors and petroleum refining units. It can effectively improve the stability and efficiency of the regeneration process, reduce energy consumption, reduce catalyst loss, extend system service life, and improve economic benefits.

[0051] like Figures 1 to 5 As shown, in this embodiment, the driving structure includes a permanent magnet and an electromagnetic component. The electromagnetic component is magnetized or demagnetized by switching the power on and off. When it is necessary to drive the first push top 51 and the second push top 52, the electromagnetic component is energized, which makes the magnetic poles of the permanent magnet and the electromagnetic component opposite, thereby enabling the first push top 51 and the second push top 52 to move closer to each other on the side near the circulation pipe 40.

[0052] like Figure 1 and Figure 2 As shown, in this embodiment, the regeneration device further includes a pump body 60, which is disposed on the circulation pipeline 40. The pump body 60 is capable of pumping the catalyst to the top of the tower 10.

[0053] In this embodiment, the pump body 60 ensures stable catalyst flow in the circulation pipeline 40, preventing catalyst blockage and uneven distribution during circulation. This is suitable for industrial processes requiring catalyst regeneration, such as flue gas purification systems in the power industry and catalytic reforming units in the petrochemical industry. It effectively improves system operating efficiency and economy, reduces catalyst loss, and lowers operating costs. By precisely controlling the operating parameters of the pump body 60, such as rotational speed and flow rate, the regeneration process can be further optimized, improving catalyst regeneration efficiency and system operational stability.

[0054] According to another aspect of this application, a carbon dioxide capture system is provided. The carbon dioxide replenishment system of this embodiment includes a regeneration device, which is the regeneration device described above. The regeneration device enables catalyst recycling, thereby improving catalytic efficiency. Therefore, the carbon dioxide replenishment system having the regeneration device also possesses the aforementioned advantages.

[0055] Specifically, this carbon dioxide capture system, through highly efficient catalyst regeneration, can significantly improve carbon dioxide capture efficiency and the economics of the regeneration process. It is suitable for various industrial processes requiring carbon dioxide capture, such as flue gas treatment systems in power plants, chemical plants, and steel mills. Particularly in carbon capture, utilization, and storage (CCUS) technology, it can effectively reduce carbon dioxide emissions, promote the development of green and low-carbon technologies, and play a positive role in achieving global carbon neutrality goals. Furthermore, because it can significantly reduce catalyst consumption and operating costs, it also has a clear economic advantage, effectively improving the economic efficiency of industrial processes and promoting sustainable industrial development. For example, in flue gas treatment systems of power plants, adopting this design can significantly reduce the cost of carbon dioxide capture and improve the system's carbon capture efficiency, which is of great significance for achieving the low-carbon transformation of the power generation industry.

[0056] The regeneration device and carbon dioxide capture system provided in this application, by incorporating a first and second section with temperature gradients within the tower body 10, combined with the use of a barrier structure 30 and a pusher structure 50, effectively improve the catalyst regeneration efficiency. In the driven state, the pusher structure 50 can advance the catalyst on the barrier membrane 31 into the circulation pipeline 40, achieving catalyst recycling. This not only reduces catalyst consumption and operating costs but also improves the safety and efficiency of the regeneration process. Simultaneously, the special design of the support frame 32 ensures uniform distribution of the catalyst within the tower body 10, further enhancing the efficiency and effectiveness of the regeneration process. This design not only significantly improves the performance of the carbon dioxide capture system in practical applications but also offers significant economic and environmental benefits. In specific applications, this design can be widely used in various industrial fields, such as energy, chemical, and environmental protection. Particularly in the field of carbon dioxide capture and utilization, it can effectively reduce carbon emissions, promote the development of green and low-carbon technologies, and play a positive role in achieving the global carbon neutrality goal. In the future, as the industrial sector continues to demand higher efficiency in catalyst regeneration and carbon dioxide capture, this design is expected to become a key technology for improving the sustainability and economic benefits of industrial processes, contributing to global environmental governance and resource recycling.

[0057] The advantages of the above scheme are that it not only effectively improves the catalyst regeneration efficiency, reduces catalyst consumption, and lowers operating costs, but also ensures uniform catalyst distribution within the tower body 10 through the special design of the support frame 32, further improving the efficiency and effectiveness of the regeneration process. This design significantly improves the performance of the carbon dioxide capture system in practical applications, resulting in significant economic and environmental benefits.
