Furthermore, immobilized carbonic anhydrase exhibits structural stability, high temperature resistance, and a long service life.

[0003] In existing technologies, immobilized carbonic anhydrase is integrated into water and sprayed onto flue gas. However, after spraying, the immobilized carbonic anhydrase cannot be collected, which means it cannot be reused, thus increasing production costs. Summary of the Invention

[0008] Furthermore, both the second and third connecting rods are arc-shaped rods, and the diameter of the circle formed by the multiple second connecting rods is smaller than the diameter of the circle formed by the multiple third connecting rods.

[0009] Furthermore, the second fastener includes a third annular portion, a fourth annular portion, a plurality of fourth connecting rods, a plurality of fifth connecting rods, and a plurality of sixth connecting rods.

Through this arrangement, the catalyst is fixed within each of the first, second, and third spherical structures, preventing catalyst loss.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0028] like Figures 1 to 3As shown, in this embodiment, the layered packing structure includes: a first fixing frame 10, a plurality of first spherical structures 20, a second fixing frame 30, a plurality of second spherical structures 40, a connecting frame 50, and a plurality of third spherical structures 60. The plurality of first spherical structures 20 are spaced apart on the first fixing frame 10. The second fixing frame 30 is spaced apart from the first fixing frame 10. The plurality of second spherical structures 40 are spaced apart on the second fixing frame 30. The connecting frame 50 connects the first fixing frame 10 and the second fixing frame 30. The plurality of third spherical structures 60 are spaced apart on the connecting frame 50. A catalyst is disposed inside each of the first spherical structures 20, the second spherical structures 40, and the third spherical structures 60.

[0029] In this embodiment, a first fixing frame 10 and a second fixing frame 30 are spaced apart, and a connecting frame 50 connects the first fixing frame 10 and the second fixing frame 30. Multiple first spherical structures 20 are spaced apart on the first fixing frame 10, multiple second spherical structures 40 are spaced apart on the second fixing frame 30, and multiple third spherical structures 60 are spaced apart on the connecting frame 50. A catalyst is disposed inside each of the first spherical structure 20, the second spherical structure 40, and the third spherical structure 60. Through this arrangement, the catalyst is fixed inside the first spherical structure 20, the second spherical structure 40, and the third spherical structure 60, respectively, preventing catalyst loss. Furthermore, since there are multiple first spherical structures 20, the second spherical structure 40, and the third spherical structure 60, a larger amount of catalyst can be fixed on the layered packing structure, thereby ensuring the catalytic effect. Therefore, the technical solution of this embodiment effectively solves the problem of catalyst loss and subsequent catalyst failure in related technologies.

[0030] This structural design, with its layered packing structure, effectively improves catalyst utilization and increases the contact area between the catalyst and the gas, thereby enhancing catalytic efficiency. It is suitable for applications in chemical production, waste gas treatment, and energy recovery, and is particularly effective in carbon dioxide capture and conversion processes, significantly improving equipment performance.

[0031] Specifically, the effect of this layered packing structure is reflected in a significant improvement in catalytic efficiency. Due to the special design of the first spherical structure 20 and the second spherical structure 40, the gas can come into contact with more catalyst during flow, effectively avoiding catalyst waste. In practical applications, this structure can significantly improve the reactor's production capacity and conversion efficiency, while reducing energy consumption and production costs. Its applications are not limited to carbon dioxide capture but are also widely applicable to the conversion and treatment of other harmful gases, such as the catalytic oxidation of VOCs (volatile organic compounds) and the desulfurization of hydrogen sulfide, playing a vital role in improving air quality and promoting environmentally friendly production.

[0032] like Figure 4 and Figure 5 As shown, in this embodiment, the first fixing frame 10 includes a first annular portion 11, a second annular portion 12, and a plurality of first connecting rods 13. The first annular portion 11 is located inside the second annular portion 12, and the plurality of first connecting rods 13 connect the first annular portion 11 and the second annular portion 12. A plurality of first spherical structures 20 are provided on both the first annular portion 11 and the plurality of first connecting rods 13. The first annular portion 11 is located inside the second annular portion 12, thus creating a gap between the first annular portion 11 and the second annular portion 12, and a gap between adjacent first connecting rods 13. This arrangement allows for a larger flow space on the first fixing frame 10, enabling flue gas to circulate. Simultaneously, the plurality of first spherical structures 20 are provided on the first annular portion 11 and the plurality of first connecting rods 13, making the position of the first spherical structures 20 more stable.

[0033] Specifically, this design not only increases structural stability but also optimizes the gas flow path through a multi-layered spherical structure layout, reducing flow resistance, enhancing gas-catalyst contact, and improving catalytic efficiency. It is widely used in chemical reactors and waste gas purification devices, effectively improving reaction rates and purification effects.

[0034] It should be noted that the multi-layered design of the first annular section 11, the second annular section 12, and the first connecting rod 13 ensures that the layered packing structure maintains good stability even when facing high-velocity gases. This effectively prevents the accumulation and blockage of the layered packing structure, guaranteeing uniform gas distribution and full utilization of the catalyst. This design is particularly suitable for large-scale chemical plants, such as petroleum cracking and synthetic ammonia production, and can improve production efficiency and reduce maintenance costs without increasing energy consumption, significantly enhancing the safety and economy of industrial production.

[0035] like Figure 4 and Figure 5 As shown, in this embodiment, the first fixing frame 10 further includes a plurality of second connecting rods 14 and a plurality of third connecting rods 15. The plurality of second connecting rods 14 are spaced apart, and each second connecting rod 14 connects two adjacent first connecting rods 13. The plurality of third connecting rods 15 are spaced apart, and each third connecting rod 15 connects two adjacent first connecting rods 13. A third connecting rod 15 is disposed between two adjacent second connecting rods 14. The arrangement of the second connecting rods 14 and the third connecting rods 15 can improve the structural strength of the first fixing frame 10 and prevent the first fixing frame 10 from deforming.

[0036] Specifically, by increasing the number and types of connecting rods (multiple second connecting rods 14 and multiple third connecting rods 15), not only is the overall stability of the structure enhanced, but more complex gas flow channels can also be formed, increasing the degree of gas turbulence and further enhancing the catalytic effect. This is suitable for industrial production processes requiring high catalytic efficiency and stability, such as petroleum refining and ammonia synthesis.

[0037] It should be noted that this complex gas flow channel design enables the gas to form a more effective turbulent state when passing through the layered packing structure, increasing the collision opportunities between the gas and the catalyst, thereby improving the rate and conversion rate of the catalytic reaction. In the petroleum refining process, it can accelerate the cracking reaction of heavy oil and increase the yield of light oil; in the synthesis of ammonia, it can improve the conversion efficiency of nitrogen and hydrogen and increase the yield of ammonia, playing an important role in improving the quality and quantity of chemical products.

[0038] like Figure 4 and Figure 5 As shown, in this embodiment, both the second connecting rod 14 and the third connecting rod 15 are arc-shaped rods, and the diameter of the circle formed by the multiple second connecting rods 14 is smaller than the diameter of the circle formed by the multiple third connecting rods 15. This arrangement ensures the structural strength of the first fixing frame 10. That is, this design can form two annular structures with different diameters, providing a richer spatial distribution for the catalyst, which is beneficial for the uniform distribution of gas in different regions, improving the uniformity and efficiency of the catalytic reaction. In fields such as waste gas treatment and chemical reactors, it can effectively improve treatment capacity and reaction rate.

[0039] Specifically, the inner and outer ring structure design allows the layered packing structure to adapt to gases with different flow rates and pressures, maintaining good catalytic performance even under conditions of large fluctuations in gas flow. In practical applications, this design is particularly suitable for waste gas treatment scenarios, such as the purification of industrial exhaust gases and the catalytic conversion of automotive exhaust gases, effectively removing harmful gases and reducing environmental pollution.

[0040] like Figures 1 to 3 As shown, in this embodiment, the second fixing frame 30 includes a third annular portion 31, a fourth annular portion 32, a plurality of fourth connecting rods 33, a plurality of fifth connecting rods 34, and a plurality of sixth connecting rods 35. The third annular portion 31 is located between the fourth annular portions 32. The plurality of fourth connecting rods 33 are spaced apart between the third annular portion 31 and the fourth annular portion 32. The plurality of fifth connecting rods 34 are spaced apart, and each fifth connecting rod 34 is connected between two adjacent third connecting rods 15. The plurality of sixth connecting rods 35 are spaced apart, and each sixth connecting rod 35 is connected between two adjacent third connecting rods 15. The above arrangement enables the second fixing frame 30 to have better structural strength and makes the position of the second spherical structure 40 more stable.

[0041] Specifically, this multi-layered ring structure design not only increases the complexity and stability of the structure, but also forms multi-level catalytic reaction zones, which is beneficial to improving the selectivity and efficiency of the reaction. It is particularly suitable for chemical processes that require precise control of reaction conditions, such as the synthesis of fine chemicals and the production of pharmaceutical intermediates.

[0042] It should be noted that the implementation of the multi-layered ring structure provides an ideal reaction environment for the synthesis of fine chemicals, especially in the synthesis of pharmaceutical intermediates. This structure can effectively control reaction conditions, improve product purity and selectivity, and reduce the formation of by-products. Furthermore, it can adapt to the needs of different reaction stages, achieving precise control of the reaction process by adjusting the distribution of catalysts and the hierarchy of reaction zones, thus significantly improving the quality and production efficiency of chemical products.

[0043] like Figure 1 , Figure 2 as well as Figure 6 As shown, in this embodiment, the connecting frame 50 includes multiple first uprights 51, multiple second uprights 52, and multiple seventh connecting rods 53. The multiple first uprights 51 are connected between the second connecting rod 14 and the fifth connecting rod 34. The multiple second uprights 52 are connected between the third connecting rod 15 and the sixth connecting rod 35. The first ends of the multiple seventh connecting rods 53 are connected one-to-one with the multiple first uprights 51, and the second ends of the multiple seventh connecting rods 53 are connected to the first connecting rods 10 and the second connecting rod 30. The first uprights 51 and the second uprights 52 can effectively connect the first fixing frame 10 and the second fixing frame 30. This results in better overall stability of the layered packing structure. Specifically, this three-dimensional frame connection method not only ensures the stability of the packing structure but also forms a three-dimensional gas flow path, further reducing flow resistance and improving the contact efficiency between the gas and the catalyst. In large-scale chemical reactors, waste gas treatment towers, and other equipment, it can significantly improve processing capacity and efficiency.

[0044] Specifically, the three-dimensional frame connection method enables the packing structure to exhibit excellent physical stability and chemical activity in large-scale equipment, maintaining its structural integrity and catalytic performance even under extreme conditions of high pressure and high temperature. This design is particularly suitable for large-scale chemical reactors, such as reforming reactors and methanol synthesis towers, significantly improving reactor processing capacity and catalyst utilization, reducing operating costs, and increasing production efficiency. In waste gas treatment towers, it can also effectively reduce the emission of harmful gases, thus having a positive impact on environmental protection.

[0045] like Figure 1 , Figure 2 as well as Figure 6As shown, in this embodiment, the layered packing structure further includes multiple fourth spherical structures 70, which are connected to multiple seventh connecting rods 53. The fourth spherical structures 70 contain a catalyst, further ensuring contact between the flue gas and the catalyst. In other words, adding fourth spherical structures 70 to the seventh connecting rods 53 not only increases the catalyst loading but also allows for a more complex gas flow pattern through the arrangement of the fourth spherical structures 70, improving the uniformity and efficiency of the catalytic reaction. This is suitable for scenarios requiring high catalytic efficiency and catalyst utilization, such as waste gas purification in environmental protection equipment and gas conversion in energy recovery equipment.

[0046] Specifically, the addition of the fourth spherical structure 70 further optimizes the contact between the gas and the catalyst, achieving more efficient catalytic conversion. In environmental protection equipment, such as industrial waste gas purification towers, this design can improve the removal efficiency of harmful gases, reduce secondary pollution, and play an important role in improving air quality. In energy recovery equipment, such as biomass gasification converters, it can improve gas conversion rates and increase the utilization efficiency of renewable resources, which is of positive significance for promoting energy transition and reducing carbon emissions.

[0047] Specifically, the first spherical structure 20, the second spherical structure 40, the third spherical structure 60, and the fourth spherical structure 70 are all made of membrane structures, which allow flue gas to pass through.

[0048] like Figures 1 to 3 As shown, in this embodiment, multiple first spherical structures 20 are connected to opposite sides of the first fixed frame 10, and multiple second spherical structures 40 are connected to opposite sides of the second fixed frame 30. This arrangement ensures that the first spherical structures 20 and second spherical structures 40 are evenly distributed on the first fixed frame 10 and the second fixed frame 30, guaranteeing contact between the flue gas and the catalyst. Specifically, this layout ensures uniform gas distribution within the layered packing structure, reduces localized catalyst overload, and improves the stability and efficiency of the catalytic reaction. In fields such as chemical production, waste gas treatment, and energy recovery, it can effectively improve the operational performance and economic efficiency of the equipment.

[0049] Specifically, the distribution of the first spherical structure 20 and the second spherical structure 40 on opposite sides of the first fixed frame 10 facilitates uniform gas penetration, avoids excessive loading of the catalyst caused by localized high-concentration gases, and improves the overall operational stability and catalyst life of the device. In chemical production, this design can increase reactor production capacity, reduce catalyst replacement frequency, and lower production costs. In waste gas treatment, it can effectively remove harmful gases, improve purification efficiency, and reduce environmental pollution. In the field of energy recovery, such as in pyrolysis gasification processes, this design can improve gas conversion rate and increase energy recovery, playing an important role in improving energy utilization efficiency.

[0050] like Figures 1 to 3 As shown, in this embodiment, the size of the first spherical structure 20 is the same as that of the second spherical structure 40, while the size of the third spherical structure 60 is larger than that of the first spherical structure 20. This arrangement ensures a good catalytic effect on the flue gas. That is, by setting the first spherical structure 20, the second spherical structure 40, and the third spherical structure 60 to different sizes, catalytic reaction zones of different sizes can be formed, which is beneficial for optimizing the residence time and catalytic efficiency of the gas in different regions. When processing gas mixtures of different particle sizes or compositions, this design can significantly improve the processing effect and efficiency, and is particularly suitable for the separation and conversion of multi-component gases.

[0051] It should be noted that the designs of the first spherical structure 20, the second spherical structure 40, and the third spherical structure 60, each with different sizes, provide an effective means of processing complex gas mixtures. In multi-component gas separation processes, such as separating hydrogen from natural gas, this design can achieve effective conversion and separation of different component gases, improving the purity of the target gas. In conversion processes, such as converting mixed gases produced by biomass gasification into syngas, it can optimize reaction conditions and increase the yield of the target product, which is of great significance for achieving efficient resource utilization and environmental protection.

[0052] The layered packing structure of this embodiment, by setting spherical structures (first spherical structure 20, second spherical structure 40, third spherical structure 60, and fourth spherical structure 70) between the fixed frames (first fixed frame 10 and second fixed frame 30), and filling the interior of the first spherical structure 20, second spherical structure 40, third spherical structure 60, and fourth spherical structure 70 with catalyst, effectively increases the surface area of ​​the catalyst and the reaction contact points, thereby improving the catalytic efficiency. Simultaneously, by setting the first spherical structure 20, second spherical structure 40, third spherical structure 60, and fourth spherical structure 70 with different sizes and distributions, the gas flow path is optimized, flow resistance is reduced, and the contact between the gas and the catalyst is enhanced, thus significantly improving the capture efficiency and operational stability of the carbon dioxide capture device, which is of great significance for environmental protection and resource recovery.

[0053] According to a second aspect of this application, a carbon dioxide capture device is provided. This embodiment of the carbon dioxide capture device includes a layered packing structure, which is the layered packing structure described above. The layered packing structure ensures the catalytic effect of the flue gas; therefore, the carbon dioxide capture device with the layered packing structure also possesses the aforementioned advantages. Specifically, by adopting the aforementioned packing structure, the carbon dioxide capture device can significantly improve capture efficiency and operational stability. In industrial production, such as high-emission industries like power, cement, and steel, this device can effectively reduce carbon dioxide emissions, which is of great significance for environmental protection and resource recovery. Furthermore, due to its highly efficient catalytic performance, it can also be applied to carbon dioxide conversion and utilization processes, such as the production of methanol and syngas, providing technical support for achieving carbon neutrality goals.

[0054] Specifically, through the above design, the packing structure and carbon dioxide capture device of this embodiment can not only effectively improve catalytic efficiency and gas handling capacity, but also adapt to the needs of different industrial scenarios, exhibiting wide applicability and economic efficiency. Especially given the current global emphasis on environmental protection and carbon emission control, this efficient and stable catalytic packing structure and capture device will become an important technological means for industries such as chemical, energy, and environmental protection, having a profound impact on promoting the development and application of green and low-carbon technologies.

[0055] It should be noted that the innovative design of the carbon dioxide capture device not only effectively reduces the carbon dioxide content in industrial emissions and greenhouse gas emissions, playing a crucial role in mitigating global warming, but also, during the conversion and utilization process, converts the captured carbon dioxide into valuable chemicals such as methanol and syngas, achieving carbon resource recovery and reuse. Its widespread application in high-emission industries such as power, cement, and steel not only significantly reduces carbon emissions but also generates additional economic benefits through the sale of byproducts, profoundly impacting the development of a green and low-carbon economy. Furthermore, the device's highly efficient catalytic performance can be applied to the capture and conversion of other greenhouse gases, such as the catalytic oxidation of methane, making a significant contribution to achieving global carbon neutrality goals.
