Description

Technical Field

[0001] This invention relates to the field of packing structure technology, and more specifically, to a packing structure and a carbon dioxide capture device having the same. Background Technology

[0002] The packing layer inside the tower serves as a mass transfer device for the gas-liquid two-phase contact. A packing support plate is installed at the bottom of the tower, and the packing is randomly placed on the support plate. A packing pressure plate is installed above the packing to prevent it from being blown away by the rising gas flow. The spray liquid is sprayed from the top of the tower onto the packing via a liquid distributor and flows down along the packing surface. Gas is introduced from the bottom of the tower, distributed by a gas distribution device, and flows counter-currently through the voids of the packing layer, achieving close contact and mass transfer between the gas and liquid phases on the packing surface. Currently, commercially available packed towers have a packing layer divided into two sections with a redistribution device in between. After redistribution, the liquid is sprayed onto the lower packing layer. While this reduces wall flow, it complicates the manufacturing structure of the packed tower.

[0003] In related technologies, the packing structure includes multiple plates spaced apart, with flow gaps between the plates, through which flue gas can pass. However, dead zones are easily generated when the flue gas passes through the flow gaps. Summary of the Invention

[0004] The main objective of this invention is to provide a packing structure and a carbon dioxide capture device having the same, so as to solve the problem that dead zones are easily generated when flue gas passes through the packing structure in related technologies.

[0005] To achieve the above objectives, according to one aspect of the present invention, a filler structure is provided, comprising: a main body, the main body comprising: a plurality of first spheres spaced apart along a predetermined direction; a plurality of second spheres spaced apart along a predetermined direction, the centers of the plurality of first spheres and the spherical shapes of the plurality of second spheres being located on a first plane; a plurality of third spheres, the centers of the plurality of third spheres being located on a second plane, the second plane being spaced apart from the first plane; and a plurality of first connecting rods, a first connecting rod being provided between any adjacent first sphere and third sphere, and a first connecting rod being provided between any adjacent second sphere and third sphere.

[0006] Furthermore, the size of the first sphere is larger than the size of the second sphere, and the size of the first sphere is larger than the size of the third sphere.

[0007] Furthermore, a third sphere is placed between any two adjacent first spheres, and a third sphere is placed between any two adjacent second spheres.

[0008] Furthermore, in the preset direction, the included angle between two adjacent first links is 45°.

[0009] Furthermore, the filler structure also includes multiple fourth spheres and multiple second connecting rods. The multiple fourth spheres are arranged in an array, with the center of each fourth sphere located on a second plane. Each fourth sphere is connected to a third sphere through at least one second connecting rod.

[0010] Furthermore, the four third spheres form a rectangular structure, with the fourth sphere located at the center of the rectangular structure.

[0011] Furthermore, the axes of the multiple second links are located on the second plane, and / or the fourth sphere is spaced apart from the second sphere in the vertical direction.

[0012] Furthermore, multiple first links and multiple second links are all elastic links.

[0013] Furthermore, the packing structure also includes a connecting ring, which is connected to the outer periphery of the main body.

[0014] According to another aspect of the present invention, a carbon dioxide capture device is provided, wherein the packing structure is the packing structure described above.

[0015] The technical solution of this invention includes a main body comprising multiple first spheres, multiple second spheres, multiple third spheres, and multiple first connecting rods. The first spheres are spaced apart along a predetermined direction, as are the second spheres. The centers of the first and second spheres are located on a first plane, and the centers of the third spheres are located on a second plane. The first and second planes are spaced apart. A first connecting rod is provided between any two adjacent first and third spheres, and between any two adjacent second and third spheres. Through this arrangement, the first, second, and third spheres are connected by multiple first connecting rods, with the centers of the first and second spheres located on the first plane and the center of the third sphere located on the second plane. This results in a larger flow clearance in the main body and a larger contact area between the main body and the flue gas. Furthermore, the arrangement of the first, second, and third spheres avoids obstructing the flue gas, enabling flow guidance and preventing dead zones. Therefore, the technical solution of this application effectively solves the problem of dead zones easily generated when flue gas passes through the packing structure in related technologies.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. 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.

[0026] like Figures 1 to 4 As shown, in this embodiment, the filler structure includes: a main body 100, which includes: a plurality of first spheres 10, spaced apart along a preset direction; a plurality of second spheres 20, spaced apart along a preset direction, wherein the centers of the plurality of first spheres 10 and the spherical shapes of the plurality of second spheres 20 are located on a first plane; a plurality of third spheres 30, the centers of the plurality of third spheres 30 being located on a second plane, which is spaced apart from the first plane; and a plurality of first connecting rods 40, wherein a first connecting rod 40 is provided between any two adjacent first spheres 10 and third spheres 30, and a first connecting rod 40 is provided between any two adjacent second spheres 20 and third spheres 30.

[0027] Applying the technical solution of this embodiment, the main body 100 includes a plurality of first spheres 10, a plurality of second spheres 20, a plurality of third spheres 30, and a plurality of first connecting rods 40. The plurality of first spheres 10 are spaced apart along a preset direction, the plurality of second spheres 20 are spaced apart along a preset direction, the centers of the plurality of first spheres 10 and the plurality of second spheres 20 are located on a first plane, and the centers of the plurality of third spheres 30 are located on a second plane. The first plane and the second plane are spaced apart, and a first connecting rod 40 is provided between any two adjacent first spheres 10 and third spheres 30, and a first connecting rod 40 is provided between any two adjacent second spheres 20 and third spheres 30. With the above configuration, the first sphere 10, the second sphere 20, and the third sphere 30 are connected by multiple first connecting rods 40. The centers of the first sphere 10 and the second sphere 20 are located on a first plane, and the center of the third sphere 30 is located on a second plane. This allows the main body 100 to have a large flow gap and a large contact area between the main body 100 and the flue gas. Furthermore, the arrangement of the first sphere 10, the second sphere 20, and the third sphere 30 avoids obstructing the flue gas and enables flow guidance, thereby preventing dead zones. Therefore, the technical solution of this embodiment effectively solves the problem of dead zones easily generated when flue gas passes through the packing structure in related technologies.

[0028] It should be noted that this packing structure design significantly increases the effective contact area of ​​the packing, improving the gas-liquid contact efficiency. It is suitable for various applications such as carbon dioxide capture, gas purification, and liquid treatment, especially in the chemical, environmental protection, and energy sectors, effectively enhancing the processing capacity and efficiency of the equipment. It achieves uniform fluid distribution and sufficient gas-liquid contact within the packing structure, thus providing higher mass transfer efficiency within the same volume. This has a significant effect on improving equipment processing capacity, reducing energy consumption, and decreasing emissions, making it an important technical means to achieve green chemical engineering and sustainable development.

[0029] like Figures 1 to 4 As shown, in this embodiment, the size of the first sphere 10 is larger than the size of the second sphere 20, and the size of the third sphere 30 is also larger. This arrangement ensures sufficient contact area between the flue gas and the main body 100.

[0030] Specifically, by combining first spheres 10 and second spheres 20 of different sizes, a more complex internal structure can be formed, increasing the degree of fluid turbulence and further improving gas-liquid contact efficiency. This is suitable for industrial processes that require high-efficiency gas-liquid contact, such as petroleum refining, chemical synthesis, and water treatment.

[0031] In practical applications, this size difference design allows the fluid to encounter more obstacles when passing through the packing structure, thereby increasing the gas-liquid phase contact path and improving mass transfer efficiency. Especially when dealing with high-viscosity fluids or fluids containing solid particles, it can effectively prevent packing blockage and ensure long-term stable operation of the equipment.

[0032] like Figures 1 to 4 As shown, in this embodiment, a third sphere 30 is disposed between any two adjacent first spheres 10, and a third sphere 30 is disposed between any two adjacent second spheres 20. This arrangement effectively blocks the flow of flue gas, preventing it from passing directly through the flow gap.

[0033] Specifically, this arrangement ensures the stability and uniformity of the packing structure, avoids local blockage, and extends the service life of the device. It is particularly suitable for treating fluids containing solid particles, such as flue gas desulfurization and wastewater treatment. This arrangement not only optimizes fluid distribution but also helps reduce dead zones between the packing materials, improving overall mass transfer efficiency. For industrial processes such as flue gas desulfurization, it can significantly increase the removal rate of sulfur dioxide, reduce harmful emissions, and protect the environment.

[0034] like Figures 1 to 4 As shown, in this embodiment, the included angle between two adjacent first connecting rods 40 in the preset direction is 45°. This arrangement ensures good overall structural strength of the main body 100.

[0035] It should be noted that this angle design can optimize the mechanical properties of the packing structure, making it more stable under fluid impact and reducing wear. It is suitable for high-pressure, high-speed fluid processing, such as high-pressure gas purification and high-speed liquid filtration.

[0036] This design effectively disperses fluid impact forces, reduces wear on the packing structure, and significantly improves the durability of the packing structure, reduces maintenance costs, and ensures efficient operation of the equipment, especially under high pressure and high speed conditions.

[0037] like Figures 1 to 4 As shown, in this embodiment, the packing structure further includes a plurality of fourth spheres 50 and a plurality of second connecting rods 60. The plurality of fourth spheres 50 are arranged in an array, with the center of each sphere located on a second plane. Each fourth sphere 50 is connected to a third sphere 30 via at least one second connecting rod 60. This arrangement further enables the blocking of flue gas, thereby increasing the contact area between the flue gas and the main body 100.

[0038] Specifically, this multi-layered sphere (first sphere 10, second sphere 20, third sphere 30 and fourth sphere 50) and connecting rod (first connecting rod 40 and second connecting rod 60) structure can further increase the specific surface area of ​​the packing and improve the treatment efficiency. It is suitable for applications requiring deep purification or treatment, such as fine chemicals, biopharmaceuticals, and food processing.

[0039] It should be noted that by adding the fourth sphere 50 and the second connecting rod 60, the complexity of the packing structure and the specific surface area are further improved, which can provide a more sufficient contact interface for complex reactions in fine chemicals, improve reaction selectivity and yield, and is suitable for the preparation process of high value-added chemical products.

[0040] like Figures 1 to 4 As shown, in this embodiment, the four third spheres 30 are arranged to form a rectangular structure, and the fourth sphere 50 is located at the center of the rectangular structure. This arrangement makes the overall structure of the main body 100 more stable.

[0041] Specifically, this layout can create a stable microenvironment, which is conducive to the uniform distribution and contact of fluids. It is particularly suitable for chemical reaction processes that require high-precision control, such as catalyst supports and bioreactors.

[0042] This layout optimizes the fluid dynamics inside the packing material, forming a microstructure that facilitates uniform dispersion and contact of reactants. For processes such as catalytic reactions and biotransformation, it can significantly improve reaction efficiency and reduce the occurrence of side reactions, making it an indispensable key component in modern fine chemicals and biotechnology.

[0043] like Figures 1 to 4 As shown, in this embodiment, the axes of the plurality of second connecting rods 60 are located on the second plane, and the fourth sphere 50 and the second sphere 20 are spaced apart in the vertical direction. This arrangement ensures sufficient contact area between the flue gas and the main body 100.

[0044] It should be noted that this design ensures the multi-directional contact capability of the packing structure, improves processing efficiency and stability, and is suitable for various complex fluid processing processes, such as multiphase flow separation and complex gas purification.

[0045] This design, by controlling the spatial relationship between different spheres, achieves effective contact and fluid dispersion of the packing structure in multiple directions, effectively improving the separation efficiency of multiphase flow and gas-liquid mass transfer in complex gas purification processes. It is of great significance for improving resource utilization and reducing environmental pollution.

[0046] like Figures 1 to 4As shown, in this embodiment, the plurality of first connecting rods 40 and the plurality of second connecting rods 60 are all elastic rods. The provision of elastic rods allows the main body 100 to undergo a certain deformation. That is, when the force of the flue gas impacting the main body 100 is large, the main body 100 can undergo a certain deformation, thereby increasing the flow gap within the main body 100 and allowing the flue gas to pass through at a faster speed.

[0047] Specifically, the design of the elastic rod allows the packing structure to generate slight vibrations under fluid impact, which helps to avoid clogging of the packing structure and extend the service life of the device. It is particularly suitable for treating fluids containing viscous substances or prone to scaling, such as oil and gas separation in oil extraction and flue gas desulfurization in the power industry.

[0048] The design of the elastic rod not only enhances the mechanical stability of the packing structure, but also effectively prevents scaling and clogging inside the packing through micro-vibration, ensuring long-term operation of the equipment when handling viscous or easily scaling fluids, reducing the frequency of equipment maintenance and cleaning, and saving operating costs.

[0049] like Figures 1 to 4 As shown, in this embodiment, the packing structure further includes a connecting ring 200, which is connected to the outer periphery of the main body 100. The connecting ring ensures the stability of the position of the main body 100.

[0050] Specifically, the design of the connecting ring 200 can increase the overall stability of the packing structure, facilitate the installation and maintenance of the packing structure, and is suitable for industrial packed towers of various sizes, such as gas purification towers in large chemical plants and reactors in small laboratories.

[0051] It should be noted that the use of the connecting ring 200 not only improves the mechanical strength of the packing structure, but also simplifies the installation and disassembly process of the packing structure, improves the convenience and safety of operation, and is suitable for different scenarios from laboratory research to industrial production, meeting the fluid handling processes of different scales and needs.

[0052] It should be noted that by adopting the packing structure of this application, through the three-dimensional network design of the first sphere 10, the second sphere 20, the third sphere 30, the fourth sphere 50, the first connecting rod 40, and the second connecting rod 60, the specific surface area of ​​the packing structure is significantly improved, the gas-liquid contact efficiency is enhanced, and thus the collection efficiency of the carbon dioxide capture device is improved.

[0053] Furthermore, the elastic rod design allows the packing structure to generate minute vibrations under fluid impact, helping to prevent clogging and extending the device's service life. This innovative packing structure design is not only suitable for carbon dioxide capture but can also be widely applied in other gas purification and liquid treatment fields, offering significant economic and social benefits.

[0054] According to another aspect of this application, a carbon dioxide capture device is provided. This embodiment of the carbon dioxide capture device includes a packing structure, which is the packing structure described above. The aforementioned packing structure can avoid the generation of dead zones; therefore, the carbon dioxide capture device having the aforementioned packing structure also has the aforementioned advantages.

[0055] Specifically, the packing structure of this application, through a three-dimensional network design of the first sphere 10, the second sphere 20, the third sphere 30, the fourth sphere 50, the first connecting rod 40, and the second connecting rod 60, significantly increases the specific surface area of ​​the packing and enhances the gas-liquid contact efficiency, thereby improving the capture efficiency of the carbon dioxide capture device. Furthermore, the design of the elastic rods allows the packing structure to generate minute vibrations under fluid impact, helping to prevent clogging of the packing structure and extending the service life of the device.

[0056] This innovative packing structure design is not only suitable for carbon dioxide capture, but can also be widely applied in other gas purification, liquid treatment, and other fields, offering significant economic and social benefits. For example, in the energy industry, it can be used for natural gas purification to remove harmful gases such as hydrogen sulfide; in the environmental protection field, it can be used for industrial wastewater treatment to improve pollutant removal rates; and in the chemical industry, it can be used for catalyst support design to improve the efficiency and selectivity of chemical reactions.

[0057] In summary, this packing structure design provides an efficient, stable, and adaptable solution for fluid handling technology, with broad application prospects and market potential.

[0058] In practical applications, this innovative design of the packing structure not only improves the processing efficiency of the equipment, but also reduces energy consumption and equipment maintenance costs.

[0059] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0060] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below."
