It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0030] like Figures 1 to 3As shown, in this embodiment, the filler ball includes: a first hemispherical cover 10, a second hemispherical cover 20, a plurality of first connecting members 31, a plurality of first accommodating balls 40, a plurality of second connecting members 32, and a plurality of second accommodating balls 50. The first hemispherical cover 10 and the second hemispherical cover 20 are buckled. The plurality of first connecting members 31 are arranged at intervals, and the first end of each first connecting member 31 is connected to the first hemispherical cover 10. The plurality of first accommodating balls 40 and the plurality of first connecting members 31 are arranged one-to-one correspondingly, and each first accommodating ball 40 is connected to the second end of the corresponding first connecting member 31, and a catalyst is placed inside each first accommodating ball 40. The plurality of second connecting members 32 are arranged at intervals, and the first end of each second connecting member 32 is connected to the second hemispherical cover 20. The plurality of second accommodating balls 50 and the plurality of second connecting members 32 are arranged one-to-one correspondingly, and each second accommodating ball 50 is connected to the second end of the corresponding second connecting member 32, and a catalyst is placed inside each second accommodating ball 50.

[0031] By applying the technical solution of this embodiment, the first hemispherical cover 10 and the second hemispherical cover 20 are buckled and arranged, a plurality of first connecting members 31 and a plurality of first accommodating balls 40 are arranged one by one, the first connecting member 31 is connected between the first hemispherical cover 10 and the first accommodating ball 40, a plurality of second connecting members 32 and a plurality of second accommodating balls 50 are arranged one by one, the second connecting member 32 is connected between the second hemispherical cover 20 and the second accommodating ball 50, and a catalyst is placed inside the first accommodating ball 40 and the second accommodating ball 50. Through the above arrangement, the catalyst is fixed in the first accommodating ball 40 and the second accommodating ball 50, and the first accommodating ball 40 and the second accommodating ball 50 are arranged between the first hemispherical cover 10 and the second hemispherical cover 20, that is, the catalyst is fixed inside the filler ball, so that the catalyst can be prevented from being lost, and then the catalyst can be prevented from being deactivated. Therefore, the technical solution of this embodiment effectively solves the problem that the immobilized carbonic anhydrase in the related art cannot be reused, thereby increasing the production cost.

[0032] Specifically, this design allows the catalyst to be evenly distributed in the first receiving ball 40, which can effectively improve the reaction efficiency and is particularly suitable for gas purification or conversion processes that require the participation of catalysts, such as industrial waste gas treatment and automobile exhaust purification. By dispersing the catalyst in multiple first receiving balls 40, not only the total surface area of ​​the catalyst is increased, but also the utilization efficiency of the catalyst is improved, the amount of catalyst used is reduced, and the cost is reduced. In practical applications, this packing ball can adapt to various gas processing equipment, such as air purifiers and chemical reactors, and significantly improve the gas purification effect and catalytic conversion rate.

[0033] like Figure 3 and Figure 4As shown, in this embodiment, the first connecting member 31 includes a first flexible rod, and the second connecting member 32 includes a second flexible rod. The first flexible rod and the second flexible rod are bendably arranged, and when smoke enters into the filler ball, the first flexible rod and the second flexible rod can be bent by the smoke, thereby enabling the first accommodating ball 40 and the second accommodating ball 50 to better contact with the smoke.

[0034] It should be noted that the design of the first flexible rod and the second flexible rod enables the filler balls to be fine-tuned according to the gas flow direction and pressure during use, ensuring the maximum contact area between the catalyst and the gas, thereby improving the catalytic efficiency. In the building ventilation system, this design can automatically adjust the distribution of the catalyst according to changes in wind direction and wind speed, thereby improving the air purification effect.

[0035] Specifically, the use of the first flexible rod and the second flexible rod enables the packing balls to automatically adapt to changes in gas flow, and maintain the optimal distribution state of the catalyst even when the direction or strength of the gas flow changes. This adaptive ability is particularly suitable for dynamically changing gas processing environments, such as high-speed building ventilation systems or chemical reactors with unstable airflow, and can significantly improve the quality of gas purification and the efficiency of catalytic conversion.

[0036] like Figure 1 , Figure 2 as well as Figure 5 As shown, in this embodiment, the first hemispherical cover 10 is provided with a first hole group 11, a second hole group 12, a third hole group 13 and a fourth hole group 14, and the first hole group 11, the second hole group 12, the third hole group 13 and the fourth hole group 14 are arranged at intervals in the direction from the top of the first hemispherical cover 10 to the bottom of the first hemispherical cover 10. The first hole group 11, the second hole group 12, the third hole group 13 and the fourth hole group 14 can improve the passability of the first hemispherical cover 10, thereby making it easier for smoke to enter the filler ball.

[0037] It should be noted that the arrangement of the first hole group 11, the second hole group 12, the third hole group 13 and the fourth hole group 14 not only optimizes the gas flow path, but also can effectively disperse the gas, avoid excessive local gas concentration, and affect the uniformity of the catalytic reaction. In the chemical industry, this design can significantly improve the efficiency and safety of the reactor. By accurately controlling the size and position of the first hole group 11, the second hole group 12, the third hole group 13 and the fourth hole group 14, the distribution of the gas inside the packing ball can be further optimized, so that the catalytic reaction can be carried out under better conditions. This design is particularly suitable for gas conversion processes in chemical reactors, such as synthetic ammonia or acetic acid production, which can significantly improve reaction efficiency, reduce energy consumption, and improve product purity, and has an important role in promoting energy conservation, emission reduction and economic benefits in the chemical industry.

[0038] Specifically, the second hemispherical cover is also provided with a first hole group 11 , a second hole group 12 , a third hole group 13 and a fourth hole group 14 .

[0039] like Figure 1 , Figure 2 as well as Figure 5 As shown, in this embodiment, the first hole group 11 includes a plurality of first holes 111 spaced apart along the circumference of the first hemispherical cover 10, the second hole group 12 includes a plurality of second holes 121 spaced apart along the circumference of the second hemispherical cover 20, the third hole group 13 includes a plurality of third holes 131 spaced apart along the circumference of the second hemispherical cover 20, and the fourth hole group 14 includes a plurality of fourth holes 141 spaced apart along the circumference of the second hemispherical cover 20. Specifically, the first hole 111 is a circular hole, and the second hole 121, the third hole 131, and the fourth hole 141 are all rectangular holes.

[0040] Specifically, the design of the circumferentially distributed multiple first holes 111 and multiple second holes 121 allows the gas to enter the packing balls from multiple directions, increasing the chance of gas contact with the catalyst, and is particularly suitable for occasions requiring high-efficiency catalytic reactions, such as waste gas treatment equipment in the environmental protection field. By providing multiple circumferentially distributed multiple first holes 111 and multiple second holes 121, the packing balls can achieve all-round gas dispersion and catalysis, reduce airflow dead corners, and improve the uniformity and efficiency of the catalytic reaction. This design is not only suitable for waste gas treatment in the environmental protection field, but can also be used in industries such as pharmaceuticals and food processing that require precise control of the gas environment, effectively improving product quality and production efficiency.

[0041] like Figure 1 , Figure 2 as well as Figure 5 As shown, in this embodiment, the size of the first hole body 111, the size of the second hole body 121, the size of the third hole body 131 and the size of the fourth hole body 141 are increased in sequence. The areas of the second hole body 121, the third hole body 131 and the fourth hole body 141 are arranged in equal proportion, and the distance between the second hole group 12 and the third hole group 13, and the distance between the third hole group 13 and the fourth hole group 14 are arranged in equal proportion.

[0042] It should be noted that the design of the first pore body 111, the second pore body 121, the third pore body 131 and the fourth pore body 141, which are gradually increased in size, can guide the gas to flow along a preset path, effectively avoid the turbulence of the gas inside the packing ball, improve the orderliness of the gas flow, and thus improve the efficiency of the catalytic reaction. In the field of energy conversion, such as the natural gas conversion process, this design can improve the conversion rate and reduce energy consumption. By controlling the size increase of the first pore body 111, the second pore body 121, the third pore body 131 and the fourth pore body 141, the packing balls can achieve step-by-step dispersion and catalysis of the gas, reduce the resistance during the gas flow process, and improve the continuity and efficiency of the catalytic conversion. This design is particularly suitable for energy processing processes such as natural gas conversion, which can significantly improve the utilization efficiency of energy and reduce energy consumption during the conversion process, and is of great significance to the sustainable development of the energy industry.

[0043] like Figures 1 to 4 As shown, in this embodiment, the material of the first receiving ball 40 is a first membrane structure, and the material of the second receiving ball 50 is a second membrane structure. The first membrane structure and the second membrane structure allow gas to pass through, thereby ensuring that smoke can pass through.

[0044] The selection of the first membrane structure and the second membrane structure mentioned above can not only protect the catalyst and prevent it from being lost, but also select different membrane materials according to different catalytic requirements to adapt to different catalytic environments. In the field of pharmaceutical synthesis, this design can effectively control the reaction conditions and improve the synthesis efficiency and product quality. By using the first containing ball 40 and the second containing ball 50 of different membrane materials, the packing balls can provide the best catalytic environment according to the characteristics and reaction requirements of different catalysts. This design is particularly suitable for the field of pharmaceutical synthesis, and can achieve precise control and efficient use of catalysts, significantly improve the efficiency and purity of drug synthesis, and play an important role in promoting technological innovation and product upgrading in the pharmaceutical industry.

[0045] like Figures 1 to 4 As shown, in this embodiment, the plurality of first accommodating balls 40 include a plurality of first spheres 41 and a plurality of second spheres 42, the diameter of the first spheres 41 is greater than the diameter of the second spheres 42, and the first spheres 41 are located between the second spheres 42 and the second hemispherical cover 20. The above arrangement enables the first hemispherical cover 10 to accommodate more first accommodating balls.

[0046] This combination design of large and small spheres (first sphere 41 and second sphere 42) can form a multi-level catalytic reaction environment, which not only increases the total surface area of ​​the catalyst, but also can provide different catalytic conditions according to the needs of different reaction stages, and is particularly suitable for catalytic reactions that need to be carried out in stages, such as catalytic cracking in the process of oil refining. By arranging the first sphere 41 and the second sphere 42 of different sizes in the packing balls, the staged control of the catalytic reaction can be achieved, so that the catalyst can play a role under the best conditions. This design is particularly suitable for catalytic cracking in the process of oil refining, can improve cracking efficiency, reduce by-product generation, and has important contributions to energy conservation and emission reduction and improving product quality in the oil industry.

[0047] According to a second aspect of the present application, a packing structure is provided, such as Figures 6 to 8 As shown, the packing structure of this embodiment includes: a fixing frame 60; a plurality of packing balls, which are arranged inside the fixing frame 60, and the packing balls are the packing balls mentioned above. The packing structure mentioned above can prevent the loss of catalyst, thereby avoiding the waste of catalyst, so the packing structure with the packing balls mentioned above also has the above advantages.

[0048] Specifically, the design of the fixing frame 60 can not only stabilize the position of the packing balls, but also be adjusted according to the size of the actual reactor, so that the packing structure can adapt to reactors of various sizes, improving the versatility and flexibility of the device. By using the fixing frame 60 to adjust the position of the packing balls, the packing structure can optimize the distribution of the catalyst and the gas flow path according to actual needs, thereby improving the controllability and efficiency of the catalytic reaction. This design is particularly suitable for reactors of various sizes, can significantly improve the flexibility of gas processing and energy conversion, and has an important role in promoting technological innovation in industries such as chemical and energy.

[0049] like Figures 6 to 8 As shown, in this embodiment, the fixing frame 60 includes a first hollow net 61 and a second hollow net 62 arranged at intervals and a plurality of connecting rods 63 connected between the first hollow net 61 and the second hollow net 62, and the plurality of connecting rods 63 are arranged at intervals. The first hollow net 61 and the second hollow net 62 can achieve the passage of smoke, thereby allowing the smoke to contact the filler balls.

[0050] like Figures 6 to 8As shown, in this embodiment, the design of the first hollow net 61, the second hollow net 62 and the connecting rod 63 not only reduces the weight of the packing structure, but also promotes the circulation of gas between the packing balls, thereby improving the overall catalytic efficiency of the packing structure. In the field of environmental protection, such as in the biofilm reactor in sewage treatment, this design can improve the contact efficiency between the biofilm and sewage and accelerate the degradation of pollutants. The design of the first hollow net 61, the second hollow net 62 and the connecting rod 63 not only improves the lightweight of the packing structure, but also promotes the uniform distribution of the airflow by increasing the gap between the packing balls, thereby improving the efficiency and stability of the catalytic reaction. This design is particularly suitable for biofilm reactors in sewage treatment, which can significantly improve the contact efficiency between the biofilm and sewage, accelerate the degradation of pollutants, and make important contributions to the sewage treatment technology and efficiency improvement in the field of environmental protection.

[0051] According to the third aspect of the present application, a carbon dioxide capture device is provided. The carbon dioxide capture device of this embodiment includes a packing structure, and the packing structure is the packing structure mentioned above. The packing structure mentioned above can prevent the loss of the catalyst, so the carbon dioxide capture device having the packing structure mentioned above also has the above advantages.

[0052] Specifically, this carbon dioxide capture device can not only efficiently capture carbon dioxide, but also adjust the type and distribution of catalysts according to actual needs, adapt to different industrial waste gases and environmental conditions, and has significant practicality and flexibility. By using the above-mentioned filler structure, the carbon dioxide capture device can adjust the type and distribution of catalysts according to the composition and concentration of different waste gases, achieve efficient capture of carbon dioxide, and reduce greenhouse gas emissions. This design is particularly suitable for industrial waste gas treatment, such as thermal power plants, cement plants, etc., and can significantly improve carbon dioxide capture efficiency and reduce carbon emissions, which is of great significance to achieving carbon neutrality goals and responding to global climate change.

[0053] It should be noted that the packing balls and packing structure proposed in the present application form a catalytic reaction environment with high flexibility and adjustability by encapsulating the catalyst in the first accommodating ball 40 and the second accommodating ball 50, and connecting the first hemispherical cover 10 and the second hemispherical cover 20 with the first connecting piece 31 and the second connecting piece 32. This design not only increases the surface area of ​​the catalyst in contact with the gas and improves the catalytic efficiency, but also further optimizes the gas flow path through the hole group setting on the first hemispherical cover 10 and the second hemispherical cover 20, so that the gas can contact the catalyst more evenly, thereby improving the efficiency of carbon dioxide capture. In addition, the structural design of the packing ball enables it to be adjusted according to actual needs in the fixed frame 60 to adapt to the reaction requirements under different conditions, and has significant practicality and flexibility. In practical applications, this packing ball and packing structure can significantly improve the performance of the carbon dioxide capture device, not only performs well in industrial waste gas treatment, but also plays an important role in many fields such as automobile exhaust purification and building ventilation systems, effectively reducing carbon dioxide emissions, and making important contributions to environmental protection and sustainable development. For example, in the exhaust gas treatment system of thermal power plants, by using this filler ball, the capture rate of carbon dioxide can be significantly improved, greenhouse gas emissions can be reduced, and the goal of carbon neutrality can be achieved. In the automotive industry, this filler structure can be used in the exhaust gas purification system to effectively reduce the carbon dioxide content in the exhaust gas and reduce the impact of automobiles on the environment. In agricultural greenhouse gas management, by applying this filler ball in the ventilation system, the carbon dioxide concentration in the greenhouse can be effectively controlled, crop growth can be promoted, and greenhouse gas emissions can be reduced at the same time, achieving environmental protection and high efficiency in agricultural production.

[0054] In practical applications, this type of filler balls and filler structure can significantly improve the performance of carbon dioxide capture devices. They not only perform well in industrial waste gas treatment, but can also play an important role in many fields such as automobile exhaust purification and building ventilation systems, effectively reducing carbon dioxide emissions and making important contributions to environmental protection and sustainable development.
