Therefore, other examples of exemplary embodiments may have different values. 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.

[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 arranged on the first fixing frame 10 at intervals. The second fixing frame 30 is arranged at intervals from the first fixing frame 10. The plurality of second spherical structures 40 are arranged on the second fixing frame 30 at intervals. The connecting frame 50 is connected between the first fixing frame 10 and the second fixing frame 30. The plurality of third spherical structures 60 are arranged on the connecting frame 50 at intervals. Catalysts are arranged inside the first spherical structures 20, the second spherical structures 40 and the third spherical structures 60.

[0029] The technical solution of the present embodiment is applied, the first fixed frame 10 and the second fixed frame 30 are arranged at intervals, the connecting frame 50 is connected between the first fixed frame 10 and the second fixed frame 30, a plurality of first spherical structures 20 are arranged at intervals on the first fixed frame 10, a plurality of second spherical structures 40 are arranged at intervals on the second fixed frame 30, and a plurality of third spherical structures 60 are arranged at intervals on the connecting frame 50. The first spherical structure 20, the second spherical structure 40 and the third spherical structure 60 are all provided with catalysts inside. Through the above-mentioned arrangement, the catalyst is respectively fixed in the first spherical structure 20, the second spherical structure 40 and the third spherical structure 60, so that the catalyst can be prevented from being lost, and because the first spherical structure 20, the second spherical structure 40 and the third spherical structure 60 are all multiple, so that more catalysts can be fixed on the layered packing structure, thereby ensuring the catalytic effect. Therefore, the technical solution of the present embodiment effectively solves the problem that the catalyst in the related art is easy to lose and thus causes the catalyst to fail.

[0030] That is, through this structural design, the layered packing structure can effectively improve the utilization rate of the catalyst, increase the contact area between the catalyst and the gas, and thus improve the catalytic efficiency. It is suitable for scenes such as chemical production, waste gas treatment, and energy recovery, especially in the process of carbon dioxide capture and conversion, which can significantly improve the performance of the device.

[0031] Specifically, the implementation effect of this layered packing structure is reflected in the significant improvement of catalytic efficiency. Due to the special design of the first spherical structure 20 and the second spherical structure 40, the gas can contact with more catalysts during the flow process, effectively avoiding the waste of catalysts. In practical applications, this structure can significantly improve the production capacity and conversion efficiency of the reactor, reduce energy consumption and production costs. The application scenarios 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), the desulfurization treatment of hydrogen sulfide, etc., which plays an important 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, the plurality of first connecting rods 13 are connected between the first annular portion 11 and the second annular portion 12, and a plurality of first spherical structures 20 are arranged on the first annular portion 11 and the plurality of first connecting rods 13. The first annular portion 11 is arranged inside the second annular portion 12, so that there is a gap between the first annular portion 11 and the second annular portion 12, and there is a gap between two adjacent first connecting rods 13, such an arrangement can make the first fixing frame 10 have more flow space, thereby allowing smoke to circulate, and at the same time, the plurality of first spherical structures 20 are arranged on the first annular portion 11 and the plurality of first connecting rods 13, so that the position of the first spherical structure 20 is more stable.

[0033] Specifically, this design not only increases the stability of the structure, but also further optimizes the gas flow path through the multi-level spherical structure layout, reduces flow resistance, enhances the contact between gas and catalyst, and improves catalytic efficiency. It is widely used in chemical reactors and waste gas purification devices, and can effectively improve the reaction rate and purification effect.

[0034] It should be noted that the multi-layered design of the first annular portion 11, the second annular portion 12 and the first connecting rod 13 enables the layered packing structure to maintain good stability when facing high-velocity gas, effectively preventing the accumulation and clogging of the layered packing structure, and ensuring the uniform distribution of gas and full utilization of the catalyst. This design is particularly suitable for large-scale chemical plants, such as petroleum cracking, synthetic ammonia production, etc., and can improve production efficiency and reduce maintenance costs without increasing energy consumption, and has a significant effect on improving 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 arranged at intervals, and each second connecting rod 14 is connected between two adjacent first connecting rods 13, the plurality of third connecting rods 15 are arranged at intervals, and each third connecting rod 15 is connected between two adjacent first connecting rods 13, and a third connecting rod 15 is arranged 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 being deformed.

[0036] Specifically, by increasing the number and types of connecting rods (multiple second connecting rods 14 and multiple third connecting rods 15), not only the overall stability of the structure is enhanced, but also a more complex gas flow channel can be formed, the turbulence of the gas is increased, and the catalytic effect is further enhanced. It is suitable for industrial production processes that require high catalytic efficiency and stability, such as petroleum refining, synthetic ammonia production, etc.

[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 speed and conversion rate of the catalytic reaction. In the oil refining process, it can accelerate the cracking reaction of heavy oil and increase the yield of light oil; in the production of synthetic ammonia, it can improve the conversion efficiency of nitrogen and hydrogen and increase the yield of ammonia, which plays an important role in improving the quality and output of chemical products.

[0038] like Figure 4 and Figure 5 As shown, in this embodiment, the second connecting rod 14 and the third connecting rod 15 are both arc-shaped rods, and the diameter of the circle surrounded by the plurality of second connecting rods 14 is smaller than the diameter of the circle surrounded by the plurality of third connecting rods 15. The above-mentioned setting can ensure the structural strength of the first fixed frame 10. That is, this design can form an annular structure with two layers of different diameters inside and outside, providing a richer spatial distribution for the catalyst, which is conducive to the uniform distribution of gas in different areas and improving the uniformity and efficiency of the catalytic reaction. In the fields of waste gas treatment, chemical reactors, etc., it can effectively improve the processing capacity and reaction rate.

[0039] Specifically, the design of the inner and outer ring structures enables the layered packing structure to adapt to gases of different flow rates and pressures, and maintain a good catalytic effect even when the gas flow rate fluctuates greatly. In practical applications, this design is particularly suitable for waste gas treatment scenarios, such as industrial exhaust purification, catalytic conversion of automobile exhaust, etc., and can effectively remove harmful gases and reduce 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 portion 32, a plurality of fourth connecting rods 33 are connected between the third annular portion 31 and the fourth annular portion 32 at intervals, a plurality of fifth connecting rods 34 are arranged at intervals, and each fifth connecting rod 34 is connected between two adjacent third connecting rods 15, a plurality of sixth connecting rods 35 are arranged at intervals, and each sixth connecting rod 35 is connected between two adjacent third connecting rods 15. The above arrangement can make the structural strength of the second fixing frame 30 better, and can make the position of the second spherical structure 40 more stable.

[0041] Specifically, the design of this multi-layer annular structure not only increases the complexity and stability of the structure, but also can form a multi-level catalytic reaction zone, which is beneficial to improve the selectivity and efficiency of the reaction. It is particularly suitable for chemical processes that require fine control of reaction conditions, such as fine chemical synthesis, pharmaceutical intermediate production, etc.

[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 the reaction conditions, improve product purity and selectivity, and reduce the generation of by-products. In addition, it can also meet the needs of reactions at different stages, and by adjusting the distribution of catalysts and the levels of reaction zones, it can achieve precise control of the reaction process, which has a significant effect on 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 a plurality of first vertical rods 51, a plurality of second vertical rods 52 and a plurality of seventh connecting rods 53, the plurality of first vertical rods 51 are connected between the second connecting rod 14 and the fifth connecting rod 34, the plurality of second vertical rods 52 are connected between the third connecting rod 15 and the sixth connecting rod 35, the first ends of the plurality of seventh connecting rods 53 are connected to the plurality of first vertical rods 51 in a one-to-one correspondence, and the second ends of the plurality of seventh connecting rods 53 are connected. The first vertical rod 51 and the second vertical rod 52 can effectively connect the first fixed frame 10 and the second fixed frame 30. Thus, the overall stability of the layered packing structure is better. Specifically, through this three-dimensional frame connection method, not only the stability of the packing structure is ensured, but also a three-dimensional gas flow path can be formed, further reducing the flow resistance and improving the contact efficiency between the gas and the catalyst. In large chemical reactors, waste gas treatment towers and other equipment, the processing capacity and efficiency can be significantly improved.

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

[0045] like Figure 1 , Figure 2 as well as Figure 6As shown, in this embodiment, the layered packing structure also includes a plurality of fourth spherical structures 70, and the plurality of fourth spherical structures 70 are connected to a plurality of seventh connecting rods 53. A catalyst is arranged inside the fourth spherical structure 70, which can further ensure that the flue gas can contact the catalyst. That is, adding a fourth spherical structure 70 to the seventh connecting rod 53 not only increases the loading amount of the catalyst, but also forms a more complex gas flow pattern through the arrangement of the fourth spherical structure 70, thereby improving the uniformity and efficiency of the catalytic reaction. It is suitable for scenarios requiring high catalytic efficiency and catalyst utilization, such as exhaust gas purification in environmental protection equipment, gas conversion in energy recovery equipment, etc.

[0046] Specifically, the addition of the fourth spherical structure 70 further optimizes the contact mode between the gas and the catalyst, and realizes a 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 rate and increase the utilization efficiency of renewable resources, which has positive significance for promoting energy transformation and reducing carbon emissions.

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

[0048] like Figures 1 to 3 As shown, in this embodiment, a plurality of first spherical structures 20 are connected to opposite sides of the first fixed frame 10, and a plurality of second spherical structures 40 are connected to opposite sides of the second fixed frame 30. The above arrangement enables the first spherical structures 20 and the second spherical structures 40 to be evenly arranged on the first fixed frame 10 and the second fixed frame 30, so that the flue gas can be in contact with the catalyst. Specifically, this layout can ensure the uniform distribution of gas in the layered packing structure, reduce the local overload of the catalyst, and improve the stability and efficiency of the catalytic reaction. In the fields of chemical production, waste gas treatment, energy recovery, etc., it can effectively improve the operating performance and economy of the device.

[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 is conducive to the uniform penetration of the gas, avoiding excessive load on the catalyst caused by local high-concentration gas, and improving the operating stability of the entire device and the life of the catalyst. In chemical production, this design can improve the production capacity of the reactor, reduce the frequency of catalyst replacement, and reduce 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 the pyrolysis gasification process, this design can improve the gas conversion rate, increase energy recovery, and play 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 the size of the second spherical structure 40, and the size of the third spherical structure 60 is larger than the size of the first spherical structure 20. The above-mentioned setting can ensure the 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 of different sizes, catalytic reaction zones of different sizes can be formed, which is conducive to the optimization of the residence time and catalytic efficiency of the gas in different areas. When it is necessary to treat a gas mixture of different particle sizes or components, this design can significantly improve the treatment effect and efficiency, and is particularly suitable for the separation and conversion process of multi-component gases.

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

[0052] The layered packing structure of this embodiment effectively increases the surface area and reaction contact points of the catalyst and improves the catalytic efficiency by arranging 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 catalyst inside the first spherical structure 20, second spherical structure 40, third spherical structure 60 and fourth spherical structure 70. At the same time, by arranging the first spherical structure 20, second spherical structure 40, third spherical structure 60 and fourth spherical structure 70 of different sizes and distributions, the gas flow path is optimized, the flow resistance is reduced, and the contact between the gas and the catalyst is enhanced, thereby significantly improving the capture efficiency and operation stability of the carbon dioxide capture device, which is of great significance to environmental protection and resource recovery.

[0053] According to the second aspect of the present application, a carbon dioxide capture device is provided. The carbon dioxide capture device of this embodiment includes a layered packing structure, and the layered packing structure is the above-mentioned layered packing structure. The above-mentioned layered packing structure can ensure the catalytic effect of the flue gas, so the carbon dioxide capture device having the above-mentioned layered packing structure also has the above-mentioned advantages. Specifically, by adopting the above-mentioned packing structure, the carbon dioxide capture device can significantly improve the capture efficiency and operation stability. In industrial production, such as high-emission industries such as electricity, cement, and steel, this device can effectively reduce carbon dioxide emissions, which is of great significance to environmental protection and resource recovery. In addition, due to its efficient catalytic performance, it can also be applied to the conversion and utilization of carbon dioxide, such as the production of methanol and synthesis gas, etc., to provide technical support for achieving the goal of carbon neutrality.

[0054] Specifically, through the above design, the filler structure and carbon dioxide capture device of this embodiment can not only effectively improve the catalytic efficiency and gas processing capacity, but also can adapt to the needs of different industrial scenarios, and have wide applicability and economy. Especially under the current global high attention to environmental protection and carbon emission control, this efficient and stable catalytic filler structure and capture device will become an important technical means for the chemical, energy, environmental protection and other industries, and will have a far-reaching 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 can not only effectively reduce the carbon dioxide content in industrial emissions and reduce greenhouse gas emissions, but also play an important role in mitigating global warming. During the conversion and utilization process, this device can convert the captured carbon dioxide into valuable chemicals such as methanol and synthesis gas, realizing the recovery and reuse of carbon resources. It is widely used in high-emission industries such as electricity, cement, and steel, which can not only significantly reduce carbon emissions, but also create additional economic benefits through the sale of by-products, which has a far-reaching impact on promoting the development of a green and low-carbon economy. In addition, the efficient catalytic performance of the device can also be applied to the capture and conversion of other greenhouse gases, such as the catalytic oxidation of methane, which makes an important contribution to achieving the global carbon neutrality goal.
