[0030] As Figures 1 to 3As shown, in this embodiment, the filler ball includes a first half-shell 10, a second half-shell 20, a plurality of first connecting pieces 31, a plurality of first containing balls 40, a plurality of second connecting pieces 32, and a plurality of second containing balls 50. The first half-shell 10 and the second half-shell 20 are snap-fitted. The plurality of first connecting pieces 31 are arranged at intervals, and the first end of each first connecting piece 31 is connected to the first half-shell 10. The plurality of first containing balls 40 and the plurality of first connecting pieces 31 are arranged one-to-one, and each first containing ball 40 is connected to the second end of the corresponding first connecting piece 31, and the inside of each first containing ball 40 is placed with a catalyst. The plurality of second connecting pieces 32 are arranged at intervals, and the first end of each second connecting piece 32 is connected to the second half-shell 20. The plurality of second containing balls 50 and the plurality of second connecting pieces 32 are arranged one-to-one, and each second containing ball 50 is connected to the second end of the corresponding second connecting piece 32, and the inside of each second containing ball 50 is placed with a catalyst.

[0031] By applying the technical solution of this embodiment, the first half-shell 10 and the second half-shell 20 are snap-fitted, the plurality of first connecting pieces 31 and the plurality of first containing balls 40 are arranged one-to-one, the first connecting piece 31 is connected between the first half-shell 10 and the first containing ball 40, the plurality of second connecting pieces 32 and the plurality of second containing balls 50 are arranged one-to-one, the second connecting piece 32 is connected between the second half-shell 20 and the second containing ball 50, and the inside of the first containing ball 40 and the second containing ball 50 is placed with a catalyst. Through the above arrangement, the catalyst is fixed in the first containing ball 40 and the second containing ball 50, the first containing ball 40 and the second containing ball 50 are arranged between the first half-shell 10 and the second half-shell 20, that is, the inside of the filler ball is fixedly provided with the catalyst, which can prevent the catalyst from being lost, and further prevent the catalyst 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 within the first containing ball 40, effectively improving the reaction efficiency, and is particularly suitable for gas purification or conversion processes that require catalyst participation, such as industrial waste gas treatment and automobile exhaust purification. By dispersing the catalyst within the plurality of first containing balls 40, not only the total surface area of the catalyst is increased, but also the utilization efficiency of the catalyst is improved, reducing the amount of catalyst used and the cost. In practical applications, this filler ball can adapt to various gas treatment equipment, such as air purifiers and chemical reactors, significantly improving the gas purification effect and catalytic conversion rate.

[0033] As Figure 3 and Figure 4As shown, in this embodiment, the first connecting member 31 comprises a first flexible rod, and the second connecting member 32 comprises a second flexible rod. The first flexible rod and the second flexible rod are bendably arranged, and can be bent by the flue gas when the flue gas enters the packing spheres, thereby enabling the first containing sphere 40 and the second containing sphere 50 to better contact the flue gas.

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

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

[0036] As shown in Figure 1 , Figure 2 and Figure 5 , in this embodiment, the first half-sphere 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, which are arranged in the direction from the top of the first half-sphere cover 10 to the bottom of the first half-sphere 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 half-sphere cover 10, thereby enabling the flue gas to more easily enter the packing spheres.

[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 effectively disperses the gas, avoiding excessive local gas concentration and affecting the uniformity of the catalytic reaction. In the chemical industry, this design can significantly improve the efficiency and safety of the reactor. By precisely 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 spheres can be further optimized, enabling the catalytic reaction to be carried out under better conditions. This design is particularly suitable for gas conversion processes in chemical reactors, such as the synthesis of ammonia or the production of acetic acid, etc., and can significantly improve reaction efficiency, reduce energy consumption, and improve product purity, playing an important role in energy saving and emission reduction and improving economic benefits in the chemical industry.

[0038] Specifically, the second half 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] As shown in Figure 1 , Figure 2 and Figure 5 , in this embodiment, the first hole group 11 includes a plurality of first hole bodies 111 arranged along the circumference of the first half cover 10, the second hole group 12 includes a plurality of second hole bodies 121 arranged along the circumference of the second half cover 20, the third hole group 13 includes a plurality of third hole bodies 131 arranged along the circumference of the second half cover 20, and the fourth hole group 14 includes a plurality of fourth hole bodies 141 arranged along the circumference of the second half cover 20. Specifically, the first hole body 111 is a circular hole, and the second hole body 121, the third hole body 131, and the fourth hole body 141 are all rectangular holes.

[0040] Specifically, the design of the plurality of circumferentially distributed first hole bodies 111 and the plurality of second hole bodies 121 allows gas to enter the packing spheres from multiple directions, increasing the opportunity for gas to contact the catalyst, and is particularly suitable for applications requiring high-efficiency catalytic reactions, such as waste gas treatment equipment in the environmental protection field. By arranging the plurality of circumferentially distributed first hole bodies 111 and the plurality of second hole bodies 121, the packing spheres can achieve all-around gas dispersion and catalysis, reducing airflow dead angles and improving the uniformity and efficiency of catalytic reactions. 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] As shown in Figure 1 , Figure 2 and Figure 5 , 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 increase in turn. The areas of the second hole body 121, the third hole body 131, and the fourth hole body 141 are set in geometric progression, and the distance between the second hole group 12 and the third hole group 13, the distance between the third hole group 13 and the fourth hole group 14, etc. are set in geometric progression.

[0042] It should be noted that the design of the first hole body 111, the second hole body 121, the third hole body 131, and the fourth hole body 141 with gradually increasing sizes can guide the gas to flow along a predetermined path, effectively avoiding turbulent flow of the gas inside the packing ball, improving the orderliness of the gas flow, and thus improving the efficiency of the catalytic reaction. In the field of energy conversion, such as natural gas conversion, this design can improve the conversion rate and reduce energy consumption. By controlling the size increment of the first hole body 111, the second hole body 121, the third hole body 131, and the fourth hole body 141, the packing ball can realize step-by-step dispersion and catalysis of the gas, reducing the resistance in the gas flow process and improving the continuity and efficiency of the catalytic conversion. This design is particularly suitable for energy processing processes such as natural gas conversion, can significantly improve the utilization efficiency of energy, reduce energy consumption in the conversion process, and has important significance for the sustainable development of the energy industry.

[0043] As shown in Figures 1 to 4 In this embodiment, the first containment sphere 40 is made of a first membrane structure, and the second containment sphere 50 is made of a second membrane structure. The first membrane structure and the second membrane structure allow the gas to pass through, thereby ensuring that the flue gas passes through.

[0044] The selection of the first membrane structure and the second membrane structure not only protects the catalyst and prevents it from being lost, but also allows different membrane materials to be selected according to different catalytic needs 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 containment sphere 40 and the second containment sphere 50 made of different membrane materials, the packing ball can provide the best catalytic environment according to the characteristics of different catalysts and reaction needs. This design is particularly suitable for the field of pharmaceutical synthesis and can achieve precise control and efficient use of catalysts, significantly improving the efficiency and purity of drug synthesis, and playing an important role in promoting technological innovation and product upgrading in the pharmaceutical industry.

[0045] As shown in Figures 1 to 4 In this embodiment, the plurality of first containment spheres 40 includes a plurality of first spheres 41 and a plurality of second spheres 42, the diameter of the first sphere 41 is greater than the diameter of the second sphere 42, and the first sphere 41 is located between the second sphere 42 and the second half-shell cover 20. The above arrangement can accommodate more first containment spheres in the interior of the first half-shell cover 10.

[0046] The combination design of the two sizes of the spheres (the first sphere 41 and the second sphere 42) can form a multi-level catalytic reaction environment, which not only increases the total surface area of the catalyst, but also provides different catalytic conditions according to the needs of different reaction stages, especially suitable for catalytic reactions that need to be carried out in stages, such as catalytic cracking in the petroleum refining process. By setting different sizes of the first sphere 41 and the second sphere 42 in the filler sphere, the staged control of the catalytic reaction can be realized, so that the catalyst can work under the best conditions. This design is particularly suitable for catalytic cracking in the petroleum refining process, which can improve the cracking efficiency and reduce the generation of by-products, and has important contribution to energy saving and emission reduction and improvement of product quality in the petroleum industry.

[0047] According to a second aspect of the present application, a filler structure is provided, such as Figures 6 to 8 As shown, the filler structure of the embodiment includes a fixing frame 60, and a plurality of filler spheres arranged inside the fixing frame 60, the filler spheres being the above-mentioned filler spheres. The above-mentioned filler structure can prevent the loss of catalyst and thus avoid the waste of catalyst, so the filler structure with the above-mentioned filler spheres also has the above-mentioned advantages.

[0048] Specifically, the design of the fixing frame 60 not only stabilizes the position of the filler spheres, but also can be adjusted according to the size of the actual reactor, so that the filler structure can adapt to reactors of various scales, improving the versatility and flexibility of the device. By adjusting the position of the filler spheres using the fixing frame 60, the filler structure can optimize the distribution of the catalyst and the gas flow path according to the actual needs, improving the controllability and efficiency of the catalytic reaction. This design is particularly suitable for reactors of various scales, which can significantly improve the flexibility of gas treatment and energy conversion, and has an important role in promoting technological innovation in the chemical industry, energy industry and other industries.

[0049] As shown in Figures 6 to 8 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 realize the passing of flue gas, so that the flue gas can contact with the filler spheres.

[0050] As shown in 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 filler structure, but also promotes the flow of gas between the filler balls, improving the overall catalytic efficiency of the filler structure. In the field of environmental protection, such as in the biological membrane reactor in wastewater treatment, this design can improve the contact efficiency of the biological membrane and the wastewater, accelerating 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 filler structure, but also promotes the uniform distribution of airflow by increasing the gap between the filler balls, improving the efficiency and stability of the catalytic reaction. This design is particularly suitable for biological membrane reactors in wastewater treatment, which can significantly improve the contact efficiency of the biological membrane and the wastewater, accelerating the degradation of pollutants, and has important contributions to the wastewater treatment technology and efficiency improvement in the field of environmental protection.

[0051] According to a third aspect of the present application, a carbon dioxide capture device is provided, the carbon dioxide capture device of the present embodiment comprises a filler structure, and the filler structure is the filler structure described above.

[0052] Specifically, this carbon dioxide capture device not only can efficiently capture carbon dioxide, but also can adjust the type and distribution of catalyst according to actual needs, adapt to different industrial waste gas and environmental conditions, and has significant practicality and flexibility. By using the filler structure described above, the carbon dioxide capture device can adjust the type and distribution of catalyst according to the composition and concentration of different waste gas, realize 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., which can significantly improve the efficiency of carbon dioxide capture and reduce carbon emissions, and has important significance for achieving carbon neutralization and responding to global climate change.

[0053] It should be noted that the filler ball and the filler structure proposed in the present application encapsulate the catalyst in the first containing ball 40 and the second containing ball 50, and connect the first half ball cover 10 and the second half ball cover 20 by the first connecting piece 31 and the second connecting piece 32, forming a highly flexible and adjustable catalytic reaction environment. This design not only increases the surface area of the catalyst in contact with the gas, improves the catalytic efficiency, but also optimizes the gas flow path through the hole group on the first half ball cover 10 and the second half ball cover 20, so that the gas can be more uniformly contacted with the catalyst, improving the efficiency of carbon dioxide capture. In addition, the structure design of the filler ball enables it to be adjusted in the fixing frame 60 according to actual needs, adapting to the reaction requirements under different conditions, and has significant practicality and flexibility. In practical application, this filler ball and filler structure can significantly improve the performance of the carbon dioxide capture device, which not only performs well in industrial waste gas treatment, but also plays an important role in automobile exhaust purification, building ventilation system and other fields, effectively reducing carbon dioxide emissions, and making important contributions to environmental protection and sustainable development. For example, in the waste gas treatment system of thermal power plants, by using this filler ball, the carbon dioxide capture rate can be significantly improved, and greenhouse gas emissions can be reduced, contributing to the carbon neutralization goal. In the automobile industry, this filler structure can be used in the exhaust purification system to effectively reduce the carbon dioxide content in the exhaust gas and reduce the impact of automobiles on the environment. In the management of greenhouse gases in agricultural greenhouses, by applying this filler ball in the ventilation system, the carbon dioxide concentration in the greenhouse can be effectively controlled, promoting crop growth, while reducing greenhouse gas emissions, achieving environmental protection and high efficiency in agricultural production.
