[0030] like Figures 1 to 6 As shown, in this embodiment, the centrifugal separation device includes: a first housing 10, a second housing 20, a plurality of screen parts 30, a rotating structure 40, a containing space 51, a discharge port 52, a feed port 53 and a driving structure 54. The second housing 20 is arranged outside the first housing 10. The plurality of screen parts 30 are arranged on the side wall of the first housing 10 at intervals. The rotating structure 40 is rotatably arranged, and the rotating structure 40 includes a rotating shaft 41 and a plurality of blades 42, and the plurality of blades 42 are all arranged on the rotating shaft 41, and the plurality of blades 42 are all arranged inside the first housing 10, and the first end of the rotating shaft 41 is located inside the first housing 10, and the second end of the rotating shaft 41 is located outside the first housing 10. The containing space 51 is arranged inside the rotating shaft 41. The discharge port 52 is arranged on the side wall of the rotating shaft 41 and communicates with the containing space 51. The feed port 53 is arranged at the second end of the rotating shaft 41 and communicates with the containing space 51. The driving structure 54 is drivingly matched with the rotating shaft 41.

[0031] The technical solution of this embodiment is applied, the first shell 10 is arranged inside the second shell 20, a plurality of screen parts 30 are arranged at intervals on the side wall of the first shell 10, the rotating structure 40 is rotatably arranged and includes a rotating shaft 41 and a plurality of blades 42, the plurality of blades 42 are all arranged on the rotating shaft 41 and are all located inside the first shell 10, the first end of the rotating shaft 41 is located inside the first shell 10, the second end of the rotating shaft 41 is located outside the first shell 10, the accommodating space 51 is arranged inside the rotating shaft 41, the discharge port 52 is arranged on the side wall of the rotating shaft 41 and communicates with the accommodating space 51, the feed port 53 is arranged at the second end of the rotating shaft 41 and communicates with the accommodating space 51, and the driving structure 54 cooperates with the rotating shaft 41. Through the above arrangement, the driving structure 54 drives the rotating shaft 41 to rotate, the material enters the accommodating space 51 from the feed port 53, and is discharged through the discharge port 52, and the material can be thrown by the blades 42 during the discharge of the material through the discharge port 52, and the material separation is realized. The liquid in the material can be discharged through the screen portion 30, and the remaining material can flow down along the side wall of the first shell 10, thereby effectively realizing the separation of the materials, that is, the separation of the immobilized enzyme and water. Therefore, the technical solution of this embodiment can effectively solve the problem in the related art that the immobilized enzyme is easily flowed away with the reaction liquid, thereby reducing the use efficiency of the immobilized enzyme.

[0032] It should be noted that the technical solution of this embodiment utilizes the principle of centrifugal force. Specifically, the centrifugal separation device can effectively separate solid particles, oil-water mixtures, etc. in the fluid under high-speed rotation. At the same time, through the accommodating space 51 and the discharge port 52 inside the rotating shaft 41, the continuous transportation of the separated materials is realized, which greatly improves the processing efficiency and continuity. In the chemical industry, this device can be used for catalyst recovery to reduce resource waste; in the pharmaceutical field, it can effectively remove impurities suspended in the solvent and improve the purity of the drug; in the food processing field, it can remove pulp fibers from fruit juice to improve product quality and taste. The design of this device not only improves the efficiency of material processing, but also greatly meets the needs of industrial production for high efficiency and stability due to its ability to operate continuously.

[0033] like Figures 2 to 6 As shown, in this embodiment, a plurality of screen parts 30 protrude outward from the side wall of the first housing 10. The above arrangement allows the water to have a certain swinging space, thereby making it easier for the water to be thrown out. That is, such a structure increases the contact area between the screen part 30 and the material, thereby improving the separation efficiency, especially when processing a fluid containing a large amount of solid particles, it can be separated more effectively, and is suitable for industrial fields such as mining, papermaking, and sewage treatment.

[0034] Specifically, the outwardly protruding design of the screen portion 30 effectively improves the separation efficiency by increasing the surface contact area, especially when dealing with fluids with high concentrations of solid particles, such as slurry in the mining industry, pulp in the papermaking industry, and sludge in the sewage treatment industry. This design can significantly improve the separation effect of solids and liquids, reduce the burden of subsequent treatment, and reduce energy consumption. In the mining industry, this device can be used for the preliminary screening and dehydration of ore to improve the recovery rate of minerals; in the papermaking industry, it can effectively remove non-fiber impurities in pulp and improve the quality of paper; in the sewage treatment industry, it can effectively intercept suspended matter, improve water quality, and reduce the impact on the environment. This design achieves more refined and efficient separation by optimizing the interaction between the screen portion 30 and the fluid, providing strong technical support for related industrial fields.

[0035] like Figures 2 to 4 as well as Figure 6 As shown, in this embodiment, there are multiple discharge ports 52, and at least one discharge port 52 is provided between any two adjacent blades 42. The above arrangement can improve the efficiency of centrifugal separation. That is, this design can evenly distribute the material, avoid local overload, ensure the stability and efficiency of the separation process, and is suitable for occasions where a large amount of fluid needs to be continuously processed, such as the continuous production process of a large chemical plant.

[0036] Specifically, the design of multiple discharge ports 52 ensures uniform distribution of the fluid under high-speed rotation, avoiding uneven separation and equipment wear caused by local overload, which is particularly important for the continuous production process of large chemical plants. In a continuously operated chemical production line, this design can ensure the smooth flow and separation efficiency of materials, avoid production interruptions caused by local blockage or overload, reduce maintenance and downtime, and improve the operational reliability and economic benefits of the production line. Especially when processing high-flow and high-viscosity fluids, such as polymer solutions, oil-based muds, etc., this design can effectively improve separation efficiency, reduce energy consumption, and provide an efficient and stable material processing solution for industries such as chemical and oil extraction.

[0037] like Figure 2 , Figure 3 as well as Figure 6 As shown, in this embodiment, the first housing 10 includes a first main body 11 and a first conical portion 12, the first main body 11 and the first conical portion 12 are connected and located above the first conical portion 12, and a plurality of screen portions 30 are arranged on the first main body 11. The arrangement of the first conical portion 12 can achieve flow diversion, and thus achieve material collection. That is, the design of the first conical portion 12 helps to concentrate and guide the material, so that the separated material can be discharged smoothly, which is particularly suitable for occasions that require rapid separation and reduction of residues, such as oil-water separation in the oil refining process.

[0038] Specifically, the design of the first conical portion 12 plays a key role in the centrifugal separation device. It not only helps to concentrate the material, but also guides the separated fluid to be discharged smoothly, reduces the material residue in the first shell 10, and improves the thoroughness and efficiency of the separation. In the oil refining industry, this design can be used for oil-water separation, effectively removes water and impurities in crude oil, and improves the quality of oil products; in biofuel production, it can achieve rapid separation of vegetable oil and water phase, and improve the production efficiency of biodiesel; in the food processing industry, such as olive oil extraction, it can effectively remove solid particles in the oil and improve the purity and taste of olive oil. This design, by optimizing the material flow path, realizes the efficiency and speed of the separation process, which has a significant promoting effect on improving product quality and production efficiency.

[0039] like Figure 2 , Figure 3 , Figure 5 as well as Figure 6 As shown, in this embodiment, there is a gap between the second housing 20 and the screen portion 30. The above arrangement allows water to enter between the second housing 20 and the first housing 10, thereby enabling water collection.

[0040] Specifically, such a spacing design can prevent the second shell 20 from directly contacting the screen portion 30, avoid wear and damage, extend the service life of the device, and is suitable for long-term operation and high-load industrial applications.

[0041] It should be noted that the spacing design between the second shell 20 and the screen part 30 is based on the consideration of maintaining the long-term stable operation of the equipment and extending the service life. This design can effectively avoid the friction and collision between the second shell 20 and the screen part 30 under high-speed rotation, reduce the wear of the equipment, and reduce the maintenance cost. In long-term operation and high-load industrial environments, such as the cooling water circulation system of a steel plant and the dust recovery system of a cement plant, this design can ensure the continuous operation of the separation device under high flow and high pressure, reduce equipment failures and downtime, and improve the overall operation efficiency and economic benefits of the system. In these high-load applications, the stability and durability of the equipment are the key, and this design just meets this demand and provides reliable support for industrial production.

[0042] like Figure 2 and Figure 3 As shown, in this embodiment, the centrifugal separation device further includes a positioning structure 60, which is disposed between the rotating shaft 41 and the first housing 10. The positioning structure 60 can position the rotating shaft 41, thereby making the rotation stability of the rotating shaft 41 better.

[0043] Specifically, the addition of the positioning structure 60 ensures the stable operation of the rotating shaft, avoids vibration and deviation during operation, enhances the reliability and safety of the device, and is suitable for precision industrial and laboratory applications requiring high-precision separation.

[0044] It should be noted that the setting of the positioning structure 60 is crucial to ensure the stability and accuracy of the centrifugal separation device under high-speed rotation. It can effectively prevent the vibration and deviation of the rotating shaft 41 during high-speed operation, which is particularly important for precision industrial and laboratory applications that require high-precision separation. In occasions such as precision electronic manufacturing, semiconductor material cleaning, and purification of biopharmaceutical products, this design can ensure the uniform distribution and fine separation of materials during the separation process, improve the consistency and purity of the product, and reduce the scrap rate in the production process. Especially in a laboratory environment, the separation and recovery of tiny particles has a direct impact on the accuracy of the experimental results. This design can provide more stable and accurate separation conditions, meeting the high standards of scientific research and quality control.

[0045] like Figures 1 to 4 As shown, in this embodiment, the second housing 20 includes a second main body 21 and a second tapered portion 22. The second main body 21 is arranged correspondingly to the first main body 11, and the second tapered portion 22 is arranged correspondingly to the first tapered portion 12. The arrangement of the second tapered portion 22 can realize the collection of water.

[0046] Specifically, this corresponding arrangement helps to form a closed fluid channel, improves the sealing performance and efficiency of the separation device, and is suitable for occasions of processing high-pressure or toxic and harmful fluids, such as harmful gas processing in chemical plants.

[0047] like Figures 1 to 4 As shown, in this embodiment, the corresponding arrangement of the second shell 20 and the first shell 10 forms a closed and efficient fluid processing channel, which not only improves the sealing and processing efficiency of the separation device, but also can effectively cope with the processing requirements of high pressure and toxic and harmful fluids, which is of great significance for the treatment of harmful gases and the production of fine chemicals in chemical plants. When processing high-pressure fluids, this design can maintain internal pressure stability, avoid leakage and pressure fluctuations, and ensure production safety; when processing toxic and harmful fluids, such as sulfuric acid, chlorine, etc., it can effectively prevent fluid leakage and protect the environment and the health of operators. In these high-risk occasions, the sealing and safety of the equipment are the primary considerations. This design significantly improves the comprehensive performance of the device by optimizing the shell structure, providing a strong guarantee for the chemical industry and environmental protection fields.

[0048] Specifically, the centrifugal separation device and system realizes efficient separation and transportation of materials by arranging a containing space 51 inside the rotating shaft 41, combined with the design of the discharge port 52 and the feed port 53. The cooperation between the rotating structure 40 and the driving structure 54 enables the device to effectively utilize centrifugal force during operation and improve the separation efficiency. The special layout of the screen part 30 not only increases the separation area, but also optimizes the fluid dynamic characteristics, further improving the separation effect. In addition, the addition of the positioning structure 60 ensures the stable operation of the rotating shaft 41, avoids vibration and deviation during operation, and enhances the reliability and safety of the device. The overall design enables the device to perform excellently in the carbon dioxide capture system, not only reducing energy consumption, but also improving the capture efficiency of carbon dioxide, which has significant benefits for environmental protection and energy conservation and emission reduction.

[0049] According to the second aspect of the present application, an absorption tower system is provided. The absorption tower system of this embodiment includes: an absorption tower 71 having a liquid inlet and a liquid outlet; a first pipeline 81 connected between the liquid inlet and the liquid outlet; a centrifugal separation device 1, which is arranged on the first pipeline 81, and the centrifugal separation device 1 is the above-mentioned centrifugal separation device 1. The above-mentioned centrifugal separation device can improve the efficiency of centrifugal separation, and can effectively achieve the separation of immobilized enzyme and water, so the absorption tower system with the above-mentioned centrifugal separation device also has the above-mentioned advantages. That is, by integrating the centrifugal separation device in the absorption tower system, solid particles and impurities in the absorption liquid can be effectively removed, the absorption efficiency and the stability of the system operation can be improved, and it is particularly suitable for carbon dioxide capture systems, and can significantly improve the capture rate and purity of carbon dioxide.

[0050] Specifically, integrating a centrifugal separation device into the absorption tower system can not only effectively remove solid particles and impurities in the absorption liquid and improve the absorption efficiency, but also maintain the stability of the system operation through continuous and automated operation, which is particularly important for the carbon dioxide capture system. In carbon capture, utilization and storage (CCUS) technology, this design can significantly improve the capture rate and purity of carbon dioxide, reduce the difficulty and cost of subsequent treatment, and play an important role in achieving carbon reduction targets in industrial processes. Especially in industries such as electricity, cement, and steel, which are major carbon dioxide emitters, the use of this high-efficiency carbon dioxide capture system can significantly reduce their carbon emissions and promote the transformation of these industries towards low-carbonization and sustainable development. The design of this system not only achieved a breakthrough in technology, but also has significant economic and environmental benefits, providing a reliable solution for achieving global carbon reduction targets.

[0051] According to a third aspect of the present application, a carbon dioxide capture system is provided, such as Figure 7As shown, the carbon dioxide capture system of this embodiment includes an absorption tower system, and the absorption tower system is the above-mentioned absorption tower system. The above-mentioned absorption tower system can show the recycling of the immobilized enzyme, thereby improving the use efficiency of the immobilized enzyme, so the carbon dioxide capture system having the above-mentioned absorption tower system also has the above-mentioned advantages.

[0052] That is, the carbon dioxide capture system can achieve efficient capture of carbon dioxide at low energy consumption through the synergistic effect of the absorption tower system and the centrifugal separation device. It is suitable for large-scale carbon dioxide emission reduction projects in the electricity, cement, steel and other industries, and is of great significance for achieving the global carbon neutrality goal.

[0053] Specifically, the integrated design of the carbon dioxide capture system combines the efficient absorption capacity of the absorption tower and the impurity removal function of the centrifugal separation device, and can achieve large-scale carbon dioxide capture at a lower energy consumption. This is one of the key technologies for achieving carbon neutrality goals for high-emission industries such as electricity, cement, and steel. In these industries, by capturing and recycling carbon dioxide, not only can greenhouse gas emissions be reduced, but the captured carbon dioxide can also be used in other industries, such as manufacturing food-grade carbon dioxide and improving oil recovery, realizing the recycling of resources and improving the economic benefits of the entire system. Driven by the global carbon neutrality goal, the scope of application of this technology will continue to expand, and its contribution to promoting global environmental protection and sustainable development will become increasingly significant. The design of this system not only reflects the power of technological innovation, but also reflects a deep commitment to environmental protection, and provides strong technical support for building a green and low-carbon future.

[0054] like Figure 7As shown, in this embodiment, the carbon dioxide capture system further includes a regeneration tower 72, a first pump body 73, a heat exchanger 74, a second pump body 75, a reboiler 76, a cooler 77 and a condenser 78, the centrifugal separation device 1 and the first pump body 73 are connected through the second pipeline 82, the first pump body 73 and the heat exchanger 74 are connected through the third pipeline 83, the heat exchanger 74 and the liquid inlet are connected through the fourth pipeline 84, the cooler 77 is arranged on the fourth pipeline 84, the heat exchanger 74 and the regeneration tower 72 are connected through the fifth pipeline 85, the heat exchanger 74 and the reboiler 76 are connected through the sixth pipeline 86, the reboiler 76 is connected to the regeneration tower 72, and the condenser 78 is connected to the regeneration tower 72 through the seventh pipeline 87. The above-mentioned arrangement can realize the capture of carbon dioxide, and the centrifugal separation device 1 can separate the immobilized enzyme from water, and the separated immobilized enzyme can be refluxed to the absorption tower 71 through the first pipeline 81, thereby realizing reuse. Specifically, this complete system design can not only efficiently capture carbon dioxide, but also realize the recycling of the absorption liquid, greatly reducing operating costs and improving the economic and environmental benefits of the system. It is suitable for industrial scenarios that require continuous operation and large-scale processing, such as the flue gas decarbonization system of thermal power plants, and can effectively reduce greenhouse gas emissions and promote sustainable development.

[0055] It should be noted that the fully integrated design of the carbon dioxide capture system realizes the complete process from absorption, separation to regeneration and reuse, which not only improves the efficiency of carbon dioxide capture, but also realizes the recycling of the absorption liquid, greatly reduces the operating cost and resource consumption, and improves the overall economic and environmental benefits of the system. In the flue gas decarbonization system of thermal power plants, this design can effectively reduce the concentration of carbon dioxide in the flue gas and reduce greenhouse gas emissions. At the same time, by regenerating and reusing the absorption liquid, it reduces the energy consumption and water consumption of the system and improves the sustainability of operation. In large-scale industrial applications, this system can operate stably and meet the processing needs of long cycles and large flows. It plays a key role in promoting the green transformation of the industrial field and achieving the global carbon neutrality goal. The design of this system not only demonstrates the potential of technological innovation, but also reflects the practice of the concept of sustainable development, and provides important technical support for building a low-carbon economy and an environmentally friendly society.
