Description

Technical Field

[0001] This invention relates to the field of carbon dioxide recovery technology, and more specifically to a packing layer support structure and a carbon dioxide absorption tower having the packing layer support structure. Background Technology

[0002] The packing layer is arranged inside the tower to ensure sufficient contact between the gas and liquid phases. The stability of the packing layer within the tower is crucial. The packing layer can hold a certain amount of liquid, forming a liquid film, which prolongs the residence time of the liquid within the tower, facilitating the full absorption of solutes from the gas. Furthermore, the presence of the packing promotes turbulent gas flow, enhancing gas-liquid mixing, helping to break up bubbles, and making it easier for solute molecules in the gas to diffuse into the liquid phase. The packing layer inside the absorption tower requires support beams for maintenance.

[0003] In related technologies, a single-layer support beam is used to support the filler. During operation, the support beam near the nozzle is easily eroded by the slurry sprayed from the spray layer on the same layer. In severe cases, it may cause blow-through, perforation, or even breakage and collapse of the spray device, threatening the safe and stable operation of the system. Summary of the Invention

[0004] This invention aims to at least partially solve one of the technical problems in related art. To this end, embodiments of this invention propose a filler layer support structure. This filler layer support structure has the advantage of high structural stability.

[0006] The packing layer support structure of this invention includes an upper crossbeam, a lower crossbeam, and a connecting beam. Both ends of the upper crossbeam and the lower crossbeam can be erected on the tower body. The upper crossbeam and the lower crossbeam are connected by the connecting beam. There are multiple connecting beams, and the multiple connecting beams are arranged in a zigzag pattern along the extension direction of the upper crossbeam. The upper end face of the upper crossbeam forms a support surface for supporting the packing layer.

[0007] The packing layer support structure of this invention, by dividing the support structure into an upper crossbeam, a lower crossbeam, and connecting beams, offers greater mechanical strength and rigidity compared to a single-layer support beam setup. This provides more stable support for the packing layer, making it suitable for high-temperature, high-pressure, or corrosive environments. Simultaneously, the two beam layers distribute the weight of the equipment within the tower more evenly, preventing overload at individual support points and reducing stress concentration, thereby extending the overall service life of the equipment. Furthermore, the zigzag arrangement of the connecting beams provides more support points for the upper and lower crossbeams, further enhancing their rigidity. Therefore, the packing layer support structure of this invention further improves the overall structural stability.

[0008] Therefore, the filler layer support structure of the present invention has the advantage of enhancing the stability of the structure.

[0015] In some embodiments, the width of the base is 1.5 to 3 times the width of the support.

[0016] In some embodiments, the lower crossbeam includes a lower beam body and extensions disposed on both sides of the lower crossbeam in the width direction, the extensions being used to connect to a distributor disposed below them, each of the connecting beams including a connected connecting beam body and a connecting base plate, the connecting base plate being connected to the lower beam body, the connecting beam body being obliquely connected between the connecting base plate and the lower end face of the upper crossbeam, and the upper end of the connecting beam body having the slot.

[0033] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0034] The following is for reference. Figures 1-6 The packing layer support structure 100 and the carbon dioxide absorption tower of the present invention are described in an embodiment.

[0035] The packing layer support structure 100 of this embodiment includes an upper crossbeam 1, a lower crossbeam 2, and a connecting beam 3. Both ends of the upper crossbeam 1 and the lower crossbeam 2 can be erected on the tower body 200. The upper crossbeam 1 and the lower crossbeam 2 are connected by the connecting beam 3. There are multiple connecting beams 3, and the multiple connecting beams 3 are arranged in a zigzag pattern along the extension direction of the upper crossbeam 1. The upper end surface 11 of the upper crossbeam 1 forms a support surface for supporting the packing layer.

[0036] The packing layer support structure 100 of this embodiment of the invention, by dividing itself into an upper crossbeam 1, a lower crossbeam 2, and a connecting beam 3, provides stronger mechanical strength and rigidity compared to a single-layer support beam setup. This allows for more stable support of the packing layer, making it suitable for high-temperature, high-pressure, or corrosive environments. Simultaneously, the two beams can more evenly distribute the weight of the equipment within the tower, preventing overload at individual support points and reducing stress concentration, thereby extending the overall service life of the equipment. Furthermore, the connecting beam 3, arranged in a zigzag pattern, provides more support points for the upper crossbeam 1 and lower crossbeam 2, further enhancing the rigidity of the packing layer support structure 100. Therefore, the packing layer support structure 100 of this embodiment of the invention further improves the overall structural stability of the tower.

[0037] Therefore, the filler layer support structure 100 of the present invention has the advantage of good structural stability.

[0038] like Figure 2 and Figure 3 As shown, there are multiple upper crossbeams 1 and multiple lower crossbeams 2. The multiple upper crossbeams 1 and multiple lower crossbeams 2 are arranged in a one-to-one correspondence along the vertical direction. The multiple upper crossbeams 1 are arranged parallel to each other at intervals along the horizontal direction, and the width of the lower crossbeams 2 is smaller than the width of the upper crossbeams 1. It can be understood that the multiple upper crossbeams 1 are arranged in parallel, and the multiple lower crossbeams 2 are arranged in parallel.

[0039] The packing layer support structure 100 of this embodiment of the invention has multiple upper crossbeams 1 and lower crossbeams 2, and the multiple upper crossbeams 1 and multiple lower crossbeams 2 are arranged in a one-to-one correspondence along the vertical direction. The dripping spray liquid is first blocked by the upper crossbeams 1, because the width of the lower crossbeams 2 is smaller than the width of the upper crossbeams 1. Therefore, the liquid dripping from the upper crossbeams 1 is less likely to fall onto the lower crossbeams 2, thus avoiding the problem of the lower crossbeams 2 being perforated, broken, or collapsed due to long-term blown damage from the spray liquid. Therefore, the packing layer support structure 100 of this embodiment of the invention helps to maintain the long-term stable operation of the packing layer support structure 100.

[0040] like Figure 5 and Figure 6 As shown, the upper crossbeam 1 has an upper end face 11, a lower end face 12, and a connecting surface 13 connecting the upper end face 11 and the lower end face 12. The area of ​​the upper end face 11 is smaller than the area of ​​the lower end face 12. The connecting beam 3 is connected to the lower end face 12. The width of the lower end face 12 is greater than the width of the lower crossbeam 2.

[0041] The packing layer support structure 100 of this embodiment of the invention, by connecting the upper end face 11 (with an area smaller than the lower end face 12) to the lower end face 12 (the larger face), not only helps to further improve the overall structural stability, but also, because the support beam itself increases the resistance to the flow of flue gas, it helps to reduce the problem of poor gas dispersion caused by the upper crossbeam 1 obstructing the corresponding flue gas flow, thereby helping to improve the dispersion of flue gas in the packing. Therefore, the packing layer support structure 100 of this embodiment of the invention helps to improve the absorption rate of flue gas.

[0042] like Figure 5 As shown, the connecting surface 13 is an arc-shaped smoke guiding surface. The flue gas flows obliquely upward along the smoke guiding surface. Thus, the filler layer support structure 100 of this embodiment of the invention further improves the flue gas dispersion.

[0043] The embodiments of the present invention are not limited thereto; for example, such as Figure 6 As shown, in other embodiments, the connecting surface 13 is an inclined smoke guiding surface in a downward direction. Similarly, the filler layer support structure 100 of this embodiment further improves the flue gas dispersion.

[0044] like Figure 5 and Figure 6 As shown, the upper crossbeam 1 includes an integrally formed base, a smoke guide part, and a support part. The width of the base is greater than that of the smoke guide part, and the width of the base is 1.5-3 times the width of the support part. The support part forms the upper end face 11 of the upper crossbeam 1, and the lower end face 12 of the base forms the lower end face 12 of the upper crossbeam 1. The side of the smoke guide part forms a smoke guide surface. The width of the base is greater than that of the lower crossbeam 2. The base has a locking protrusion, and the connecting beam 3 has a locking groove. The locking groove of the connecting beam 3 is locked onto the locking protrusion.

[0045] The filler layer support structure 100 of this embodiment is divided into an integrally formed base, a smoke guiding part, and a support part by an upper crossbeam 1. The base has a locking protrusion, and the connecting beam 3 has a locking groove. The locking groove of the connecting beam 3 is engaged with the locking protrusion, thereby improving the connection stability between the connecting beam 3 and the upper crossbeam 1. Thus, the filler layer support structure 100 of this embodiment further improves the stability of the structure.

[0046] like Figure 4 As shown, the filler layer support structure 100 of this embodiment of the invention also includes an upper crossbeam 1 including a plurality of reinforcing ribs 14. The plurality of reinforcing ribs 14 are spaced apart on the smoke guide portion and the base along the length extension direction of the base, and the reinforcing ribs 14 extend along the smoke guide surface.

[0047] The filler layer support structure 100 of this embodiment of the invention has multiple reinforcing ribs 14, which are spaced apart on the smoke guide and the base along the length extension direction of the base. This helps to further improve the overall stability of the filler layer support structure 100 without obstructing the flow of flue gas.

[0048] Furthermore, the width of the lower end face is 1.5 to 3 times the width of the upper end face.

[0049] The filler layer support structure 100 of this embodiment of the invention avoids the problems of poor flue gas guidance and poor flue gas uniformity caused by an excessively small ratio of base width to support width, and also avoids the problem of low structural strength caused by an excessively large ratio. Therefore, the filler layer support structure 100 of this embodiment of the invention has the advantage of improving the uniformity of flue gas dispersion while ensuring structural strength.

[0050] Optionally, the width of the base is 1.5, 1.6, 1.7, 1.8, 1.9, 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9 or 3.0 times the width of the support.

[0051] like Figure 5 and Figure 6 As shown, the lower crossbeam 2 includes a lower beam body 21 and extensions 22 disposed on both sides of the lower crossbeam 2 in the width direction. The extensions 22 are used to connect with the distributor disposed below them. Each connecting beam 3 includes a connected connecting beam body 31 and a connecting base plate 32. The connecting base plate 32 is connected to the lower beam body 21. The connecting beam body 31 is obliquely connected between the connecting base plate 32 and the lower end face 12 of the upper crossbeam 1. The upper end of the connecting beam body 31 has a slot.

[0052] The filler layer support structure 100 of this embodiment of the invention, by connecting each connecting beam 3 to a connecting beam body 31 and a connecting base plate 32 respectively, with the connecting base plate 32 connected to the lower beam body 21, and the connecting beam body 31 connected to the lower beam body 21 through the connecting base plate 32, helps to increase the connection area 13 between the connecting beam body 31 and the lower beam body 21. Therefore, the filler layer support structure 100 of this embodiment of the invention further improves the stability of the structure.

[0053] The upper crossbeam 1 is externally bonded with an erosion-resistant layer (not shown). This erosion-resistant layer enhances the impact resistance of the support beam. Furthermore, the filler layer support structure 100 of this embodiment helps to improve the service life of the support beam.

[0054] Alternatively, the erosion-resistant layer can be a polypropylene layer.

[0055] The filler layer support structure 100 of this embodiment of the invention also includes a support base 4, which includes a base body and a spring support. The base body can be connected to the side wall of the tower body 200, and the spring support is disposed on the upper end face 11 of the base body. The upper crossbeam 1 is supported on the spring support.

[0056] The packing layer support structure 100 of this embodiment of the invention divides the support base 4 into a base body and a spring support. The spring support can absorb and buffer vibration energy, reducing the transmission of vibration to other structural parts, thereby reducing the vibration amplitude of the tower body 200 and protecting the equipment from damage. Furthermore, the spring support allows the structure to move freely according to temperature changes, reducing thermal stress and preventing structural damage caused by thermal expansion and contraction. Simultaneously, the spring support can also reduce stress concentration and extend the service life of the equipment. Therefore, the packing layer support structure 100 of this embodiment of the invention has the advantage of further improving structural stability.

[0057] The carbon dioxide absorption tower of this invention includes a tower body 200, a packing block 400, and a packing layer support structure 100 according to any one of the above. The tower body 200 has a chamber, and the tower body 200 is provided with an air inlet and an exhaust outlet. The packing layer support structure 100 is disposed in the chamber, and the packing layer support structure 100 and the tower body 200 define a reaction chamber. The packing block 400 is filled in the reaction chamber.

[0058] Therefore, the carbon dioxide absorption tower of the present invention has the advantage of enhanced structural stability.

[0059] The carbon dioxide absorption tower of this embodiment of the invention also includes a cooling component 300, and multiple packing blocks 400 are provided. The cooling component 300 is arranged in a crisscross pattern in the reaction chamber and defines multiple packing compartments with the tower body 200. Multiple packing blocks 400 are correspondingly arranged in the packing compartments. Refrigerant circulates in the cooling component 300.

[0060] In this embodiment of the carbon dioxide absorption tower, cooling components 300 are arranged in a crisscross pattern within the reaction chamber. These cooling components, along with the tower body 200, define multiple packing compartments. This allows the absorbent to absorb CO2 while simultaneously changing from indirect heat exchange to direct contact heat exchange, thereby maintaining the absorbent at a relatively low temperature (because a relatively low temperature results in relatively high adsorption capacity). This helps to increase the concentration of the rich solution and improve the CO2 adsorption efficiency. Furthermore, this embodiment of the carbon dioxide absorption tower helps to reduce the energy consumption for flue gas treatment.

[0061] In addition, the cooling components 300 are arranged in a crisscross pattern in the reaction chamber to exchange heat directly with the adsorbent. There is no need to collect the absorbent liquid and export it outside the tower body 200 and then circulate it to the outside of the tower for cooling by a circulating pump. Only heat exchange pipes need to be installed inside the tower body 200, which reduces the investment cost of the equipment.

[0062] Therefore, the carbon dioxide absorption tower of the present invention has the advantages of reducing energy consumption, improving heat exchange efficiency, and reducing equipment investment.

[0063] Optionally, the cooling assembly 300 includes a heat exchanger 301, a manifold 302, a plurality of main pipes 303 and a plurality of branch pipes 304. The heat exchanger 301 is connected to the plurality of main pipes 303 through the manifold 302. The plurality of branch pipes 304 are all connected to the main pipes 303. The plurality of main pipes 303 extend along the extension direction of the packing layer support structure 100. The plurality of branch pipes 304 extend along the height direction of the tower body 200 to define the packing compartments. The plurality of branch pipes 304, together with the packing layer support structure 100 and / or the tower body 200, define the packing compartments.

[0064] The carbon dioxide absorption tower of this embodiment of the invention divides the cooling assembly 300 into a heat exchanger 301, a manifold 302, multiple main pipes 303, and multiple branch pipes 304. The multiple main pipes 303 extend along the extension direction of the packing layer support structure 100, and the multiple branch pipes 304 extend along the height direction of the tower body 200. This achieves heat exchange at the bottom edge and multiple sides of the packing block 400, not only improving heat exchange efficiency but also contributing to improved temperature uniformity of the absorbent. Therefore, the carbon dioxide absorption tower of this embodiment of the invention helps to further improve the absorption efficiency of the absorbent.

[0065] Furthermore, multiple main pipes 303 extend in a direction perpendicular to the height of the tower body 200, and multiple branch pipes 304 can be regularly arranged to form multiple packing compartments with triangular, square, or rectangular structures. That is, multiple branch pipes 304 can be arranged inside the reaction chamber and sandwiched between adjacent packing blocks 400. Thus, the carbon dioxide absorption tower of this embodiment of the invention greatly improves the heat exchange efficiency.
