Description

Technical Field

[0001] The present invention relates to the technical field of carbon dioxide capture, and in particular to a regeneration device and a carbon dioxide capture system having the same. Background Art

[0002] The burning of fossil fuels and biomass has led to the continuous accumulation of carbon dioxide in the atmosphere, resulting in a serious greenhouse effect. At the same time, carbon dioxide is widely used in various fields such as food, industry, agriculture, medicine, national defense, and commerce, and has potential resource value, so it is urgent to realize its resource utilization through the capture of carbon dioxide.

[0003] At present, carbon dioxide is mainly captured by recycling and reprocessing from industrial by-product gases, flue gases, kiln gases and waste gases. The main carbon dioxide capture processes include solvent absorption, pressure swing absorption, membrane permeation separation, etc. The solvent absorption method has the advantages of high purification, small equipment footprint, and easy regeneration, and is widely used in industry. The solvent absorption method mainly absorbs carbon dioxide by spraying an organic amine absorption tower. Due to different industrial needs, cylindrical absorption towers of different heights filled with fillers are usually selected.

[0004] In the related art, in order to improve the efficiency of carbon dioxide capture, a catalyst, namely carbonic anhydrase, is usually used. Immobilized carbonic anhydrase is applied to the carbon dioxide absorption tower to accelerate the absorption rate of carbon dioxide. However, the immobilized enzyme generally has small particles. During the reaction, the immobilized enzyme often flows away with the reaction liquid and then enters the high-temperature area in the tower, which will cause the immobilized enzyme to be inactivated, thereby reducing its use efficiency. After the reaction is completed, it is difficult to separate it from the absorption tower filler, which increases the use cost. Summary of the invention

[0005] The main purpose of the present invention is to provide a regeneration device and a carbon dioxide capture system having the same, so as to solve the problem in the related art that the immobilized enzyme is easily flowed to the high temperature area with the reaction liquid, which easily leads to the inactivation of the immobilized enzyme.

[0006] In order to achieve the above-mentioned purpose, according to one aspect of the present invention, a regeneration device is provided, comprising: a tower body, comprising a first part and a second part, the first part is located below the second part, and the temperature at the first part is greater than the temperature at the second part; an air intake structure, connected to the bottom of the tower body; a blocking structure, arranged in the second part, the blocking structure comprising a blocking membrane allowing gas to pass through; a circulation pipeline, the first end of the circulation pipeline is connected to the side wall of the tower body and is located above the blocking structure, and the second end of the circulation pipeline is connected to the top of the tower body; a pushing structure, arranged inside the tower body and located on the blocking membrane, the pushing structure having a driving state and a stopping state; wherein, when the pushing structure is in the driving state, the pushing structure can push the catalyst on the blocking membrane into the circulation pipeline.

[0009] Further, the raised portion is a cone, the connecting portion is a connecting ring, and the width a of the connecting ring and the maximum diameter b of the cone satisfy: 0.08≤a / b≤0.25. Further, the connecting portion is provided with a plurality of first hollow areas, and the raised portion is provided with a plurality of second hollow areas.

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

[0011] Further, the first pushing part includes a first pushing plate and a second pushing plate connected to each other, the second pushing part includes a third pushing plate and a fourth pushing plate connected to each other, the first pushing plate and the third pushing plate are both arranged on the connecting part, and the second pushing plate and the fourth pushing plate are both arranged on the protruding part.

[0012] Furthermore, the regeneration device also includes a driving structure, which can synchronously drive the first pushing top part and the second pushing top part to move.

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

[0027] Carbonic anhydrase is a metalloprotein widely found in organisms, which can efficiently catalyze the hydration and dehydration reactions of carbon dioxide. In industrial applications, immobilized carbonic anhydrase can be used in batches. On the one hand, it reduces the cost of enzyme use and avoids enzyme contamination of the reaction system. On the other hand, immobilized carbonic anhydrase has a stable structure, high temperature resistance, and a long service life.

[0028] Applying immobilized carbonic anhydrase in a carbon dioxide absorption tower can speed up the absorption rate of carbon dioxide. However, immobilized enzyme particles are generally small, and during the reaction process, the immobilized enzyme often flows away with the reaction liquid, reducing its use efficiency. After the reaction is completed, it is difficult to separate it from the absorption tower filler, increasing the use cost.

[0029] In order to solve the above technical problems, such as Figures 1 to 3 As shown, in this embodiment, the regeneration device includes: a tower body 10, an air intake structure 20, a blocking structure 30, a circulation pipeline 40 and a push-up structure 50. The tower body 10 includes a first part and a second part, the first part is located below the second part, the temperature at the first part is greater than the temperature at the second part, and the air intake structure 20 is connected to the bottom of the tower body 10. The blocking structure 30 is arranged in the second part, and the blocking structure 30 includes a blocking film 31 that allows gas to pass through. The first end of the circulation pipeline 40 is connected to the side wall of the tower body 10 and is located above the blocking structure 30, and the second end of the circulation pipeline 40 is connected to the top of the tower body 10. The push-up structure 50 is arranged inside the tower body 10 and is located on the blocking film 31. The push-up structure 50 has a driving state and a stopping state. Among them, when the push-up structure 50 is in the driving state, the push-up structure 50 can push the catalyst on the blocking film 31 into the circulation pipeline 40.

[0030] According to the technical solution of this embodiment, the air intake structure 20 is connected to the bottom of the tower body 10, and the blocking structure 30 is arranged inside the tower body 10. The blocking structure 30 includes a blocking film 31, and the blocking film 31 can allow gas to pass through. The first end of the circulation pipeline 40 is connected to the side wall of the tower body 10 and is located above the blocking structure 30, and the second end of the circulation pipeline 40 is connected to the top of the tower body 10. The push-up structure 50 is arranged inside the tower body 10 and is located on the blocking film 31. The push-up structure 50 has a driving state and a stopping state. When the push-up structure 50 is in the driving state, the push-up structure 50 can push the catalyst on the blocking film 31 into the circulation pipeline 40. Through the above arrangement, the flue gas can enter the interior of the tower body 10 through the air intake structure 20. After entering the interior of the tower body 10, the flue gas passes through the blocking film 31 from the bottom of the blocking structure 30 and enters the top of the blocking structure 30, that is, it enters from the first part to the second part. The push-up structure 50 can push the catalyst on the barrier film 31 into the circulation pipeline 40 and enter the interior of the tower body 10 from the second end of the circulation pipeline 40, while achieving contact with the flue gas for catalysis. When the catalyst falls onto the barrier film 31, it can be pushed again by the push-up structure 50, and then collected again, so as to achieve the recycling of the catalyst, thereby avoiding the waste and failure of the catalyst. Therefore, the technical solution of this embodiment effectively solves the problem that the immobilized enzyme in the related art is easy to flow to the high temperature area with the reaction liquid, which easily leads to the inactivation of the immobilized enzyme. Specifically, this design can effectively improve the regeneration efficiency of the catalyst by utilizing the natural temperature gradient from the bottom to the top of the tower body 10, especially in the cycle process where the catalyst needs to undergo high-temperature regeneration and low-temperature cooling, which can significantly shorten the regeneration cycle and reduce energy consumption. It is suitable for various industrial processes that require catalyst regeneration, such as chemical industry, petroleum refining, and environmental protection fields, especially in carbon dioxide capture systems, which can significantly improve the operating efficiency and economy of the system, reduce the loss of catalysts, and extend the service life of the system.

[0031] The above-mentioned temperatures refer to working temperatures.

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

[0033] like Figure 1 and Figure 2 As shown, in this embodiment, the tower body 10 includes a first part and a second part, the first part is located below the second part, the temperature at the first part is greater than the temperature at the second part, and the blocking structure 30 is arranged in the second part. The above arrangement can make the catalyst in a position with lower temperature, thereby preventing the catalyst from being deactivated.

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

[0035] It should be noted that the support frame 32 can not only stabilize the barrier film 31, but also ensure the uniform distribution of the catalyst in the tower body 10, improve the uniformity and efficiency of the regeneration process, and avoid local overheating or insufficient regeneration caused by catalyst accumulation. It is particularly suitable for large industrial devices that require catalyst recycling, such as flue gas purification systems in power plants and catalytic cracking units in refineries, which can effectively improve regeneration efficiency, reduce energy consumption, and ensure the stability of system operation.

[0036] like Figures 3 to 5 As shown, in this embodiment, the support frame 32 includes a connecting portion 321 and a protruding portion 322, the connecting portion 321 is connected to the outer periphery of the protruding portion 322, and the cross-sectional area of ​​the protruding portion 322 gradually increases from the top of the tower body 10 to the bottom of the tower body 10. The arrangement of the protruding portion 322 can achieve flow diversion, that is, the catalyst of the fluid can flow downward on the side wall of the protruding portion 322 to the connecting portion 321, thereby preventing the catalyst from accumulating on the barrier film 31, thereby ensuring that the catalyst can be reused.

[0037] Specifically, the support frame 32 of this design can better adapt to the change of temperature gradient in the tower body 10, ensure the uniform distribution of catalyst in different temperature areas, thereby improving the regeneration efficiency, while reducing the resistance of gas flow and maintaining good gas distribution. It is suitable for various regeneration processes with temperature gradients, such as catalyst regeneration in chemical reactors and petroleum refining devices, especially when processing large and complex industrial waste gas, and can effectively improve the utilization rate of catalysts and the overall efficiency of the regeneration system. Figures 3 to 5 As shown, in this embodiment, the protrusion 322 is a cone, the connecting portion 321 is a connecting ring, and the width a of the connecting ring and the maximum diameter b of the cone satisfy: 0.08≤a / b≤0.25. The above setting can ensure that the catalyst flows evenly to 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 above-mentioned proportion design can ensure the stable distribution of the catalyst on the support frame 32 without affecting the circulation of gas, and is suitable for industrial processes that require catalyst regeneration, such as catalytic cracking regeneration systems in oil refining. By accurately controlling the proportion of the support frame 32, it is possible to effectively avoid excessive accumulation of catalysts in high-temperature areas, reduce the risk of catalyst sintering, and ensure sufficient cooling of the catalyst in the low-temperature area, thereby improving the safety and efficiency of the regeneration process.

[0039] Specifically, in this embodiment, a plurality of first hollow areas are provided on the connecting ring, 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 can ensure the structural strength of the connecting ring on the one hand, and avoid blocking too large an area of ​​smoke flow on the other hand.

[0040] Similarly, the raised portion 322 is provided with a plurality of second hollow areas, which are arranged at intervals along the circumference of the raised portion, and a solid portion is provided between two adjacent second hollow portions, and a plurality of through holes are provided on the solid portion, and the diameters of the plurality of through holes gradually increase from the top of the raised portion 322 to the bottom of the raised portion 322. This can also ensure the flow effect of the smoke and the structural strength of the raised portion 322.

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

[0042] Specifically, the design of the hollow area can increase the contact area between the gas and the catalyst, improve the regeneration efficiency, and reduce the weight of the support frame 32, reduce the manufacturing cost and energy consumption, and is suitable for environmental protection equipment that requires catalyst regeneration, such as the catalyst regeneration module in the air purifier. In practical applications, this design can significantly increase the activity recovery speed of the catalyst and reduce the regeneration time. At the same time, through the optimized layout of the hollow area, the uniformity of the gas flow can be improved, and the regeneration effect of the catalyst and the processing capacity of the equipment can be further improved.

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

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

[0045] It should be noted that the push-up structure 50 of this design can effectively push the catalyst into the circulation pipeline 40, realize the recycling of the catalyst, reduce the static storage time of the catalyst, avoid the activity loss of the catalyst, and is suitable for industrial equipment that requires catalyst recycling, such as the catalyst regeneration system of a chemical plant. This coordinated motion design can ensure the continuity and uniformity of the catalyst during the circulation process, significantly reduce the consumption of the catalyst, reduce operating costs, and improve the stability and reliability of the system.

[0046] like Figures 2 to 4 As shown, in this embodiment, the first pushing part 51 includes a first pushing plate 511 and a second pushing plate 512 connected to each other, and the second pushing part 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 arranged on the connecting portion 321, and the second pushing plate 512 and the fourth pushing plate 522 are both arranged on the protruding portion 322. The structures of the first pushing plate 511, the second pushing plate 512, the third pushing plate 521 and the fourth pushing plate 522 are simple and convenient to arrange, the first pushing plate 511 and the third pushing plate 521 can push and scrape the catalyst on the blocking 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 blocking film 31 located on the protruding portion 322.

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

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

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

[0050] Specifically, the setting of the driving structure can ensure the synchronization and stability of the pushing process, avoid uneven distribution of the catalyst during the pushing process, and improve the controllability and efficiency of the regeneration process. It is suitable for industrial equipment that requires catalyst regeneration, such as large chemical reactors and catalyst regeneration systems of petroleum refining units. It can effectively improve the stability and efficiency of the regeneration process, reduce energy consumption, and at the same time reduce catalyst loss, extend the service life of the system, 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 magnetic or non-magnetic by turning on and off the power. When it is necessary to drive the first pushing part 51 and the second pushing part 52, the electromagnetic component is energized, so that the magnetic poles of the permanent magnet and the electromagnetic component are opposite, so that the first pushing part 51 and the second pushing part 52 can be close to each other on the side close to the circulation pipeline 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 can pump the catalyst to the top of the tower body 10.

[0053] In this embodiment, the pump body 60 is arranged to ensure the stable flow of the catalyst in the circulation pipeline 40, avoid the blockage and uneven distribution of the catalyst during the circulation process, and is suitable for industrial processes that require the recycling and regeneration of the catalyst, such as the flue gas purification system in the power industry and the catalytic reforming device in the petrochemical industry, and can effectively improve the operating efficiency and economy of the system, reduce the loss of the catalyst, and reduce the operating cost. By accurately controlling the operating parameters of the pump body 60, such as the speed and flow rate, the regeneration process can be further optimized, and the regeneration effect of the catalyst and the stability of the system operation can be improved.

[0054] According to another aspect of the present application, a carbon dioxide capture system is provided. The carbon dioxide capture system of this embodiment includes a regeneration device, and the regeneration device is the above-mentioned regeneration device. The above-mentioned regeneration device can realize the circulation of the catalyst, thereby improving the catalytic efficiency. Therefore, the carbon dioxide capture system having the above-mentioned regeneration device also has the above-mentioned advantages.

[0055] Specifically, this carbon dioxide capture system can significantly improve the capture efficiency of carbon dioxide and the economy of the regeneration process through efficient catalyst regeneration. It is suitable for various industrial processes that require carbon dioxide capture, such as flue gas treatment systems in power plants, chemical plants, and steel plants. Especially in carbon capture, utilization, and storage (CCUS) technology, it can effectively reduce carbon dioxide emissions and promote the development of green and low-carbon technologies, which has a positive role in achieving global carbon neutrality goals. In addition, since it can significantly reduce catalyst consumption and reduce operating costs, it also has obvious advantages in terms of economy, which can effectively improve the economic benefits of industrial processes and promote the sustainable development of industry. For example, in the flue gas treatment system of a power plant, the use of this design can significantly reduce the cost of carbon dioxide capture and improve the carbon capture efficiency of the system, which is of great significance for achieving a low-carbon transformation in the power generation industry.

[0056] The regeneration device and carbon dioxide capture system provided in the present application can effectively improve the regeneration efficiency of the catalyst by arranging a first part and a second part with a temperature gradient in the tower body 10, combined with the use of a blocking structure 30 and a push-up structure 50. In the driving state, the push-up structure 50 can push the catalyst on the barrier film 31 into the circulation pipeline 40 to realize the recycling of the catalyst, which not only reduces the consumption of the catalyst, reduces the operating cost, but also improves the safety and efficiency of the regeneration process. At the same time, through the special design of the support frame 32, it is possible to ensure that the catalyst is evenly distributed in the tower body 10, further improving the efficiency and effect of the regeneration process. This design not only significantly improves the performance of the carbon dioxide capture system in practical applications, but also has significant economic and environmental benefits. In specific applications, this design can be widely used in various industrial fields, such as energy, chemical industry and environmental protection, especially in the field of carbon dioxide capture and utilization, can effectively reduce carbon emissions, promote the development of green and low-carbon technologies, and have a positive role in achieving global carbon neutrality goals. In the future, as the industrial field's requirements for catalyst regeneration and carbon dioxide capture efficiency continue to increase, this design is expected to become a key technology to improve the sustainability and economic benefits of industrial processes, and contribute to global environmental governance and resource recycling.

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