Description

Technical Field

[0001] The present invention relates to the technical field of carbon dioxide capture, and in particular to a tower structure and a carbon dioxide capture system having the same. Background Art

[0002] At present, the liquid in the regeneration tower with built-in membrane is added from the top of the tower, sprayed onto the packing through the liquid distributor, and flows down along the gaps in the packing. The gas is fed into the tower from the bottom, and after being distributed by the gas distribution device, it continuously passes through the gaps in the packing layer in countercurrent with the liquid, and the gas-liquid two-phase is in close contact for mass transfer. When the gas flows to the top of the tower, the condenser at the top of the tower condenses part of the steam, and the condensed steam flows into the tower again, and the remaining gas flows out. When the liquid flows to the bottom of the tower, the reboiler at the bottom of the tower vaporizes part of the liquid, and the vaporized liquid rises along the tower again, and the remaining liquid flows out. The feed flows in from the middle of the tower, and the steam in the feed rises together with the steam in the tower, and the liquid in the feed falls together with the liquid in the tower. When the liquid flows down along the packing layer, it tends to gradually concentrate on the tower wall, so that the liquid flow near the tower wall gradually increases. This phenomenon is called wall flow. The wall flow effect causes corrosion and wear of the tower wall. At the same time, the gas and liquid are unevenly distributed in the packing layer, which reduces the mass transfer efficiency and affects the quality of the finished product. Summary of the invention

[0005] Furthermore, the flow guiding structure comprises a spiral tube, and the pitch of the spiral tube gradually decreases in the direction from the bottom of the tower body to the top of the tower body.

[0010] Furthermore, the plurality of spiral channels include forming a plurality of spiral groups, each spiral group includes a plurality of spiral channels, and the plurality of spiral channels are sequentially arranged in a direction from the center of the filling block to the periphery of the filling block.

[0011] Furthermore, the plurality of spiral groups include a first spiral group, a second spiral group and a third spiral group arranged in sequence from the center of the filling block to the periphery of the filling block, and the pitch of the spiral channel in the first spiral group is smaller than the pitch of the spiral channel in the second spiral group.

[0012] Furthermore, the absorption tower also includes a collecting structure, which is arranged inside the tower body and below the filling blocks.

[0013] According to another aspect of the present invention, a carbon dioxide capture system is provided, comprising a tower structure, wherein the tower structure is the tower structure described above.

At the same time, it can prevent the smoke from blowing the liquid onto the inner wall of the tower body, so as to avoid the wall flow phenomenon.

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 Figure 1 , Figure 2 as well as Figure 4 As shown, in this embodiment, the tower structure includes: a tower body 10, an air inlet pipe 20, an air outlet pipe 30, a guide structure 40 and a packing structure 50. The air inlet pipe 20 is arranged at the bottom of the tower body 10. The air outlet pipe 30 is arranged at the top of the tower body 10. The guide structure 40 is arranged inside the tower body 10 and communicated with the air inlet pipe 20, and the guide structure 40 can guide the smoke to the center of the tower body 10. The packing structure 50 is arranged in the tower body 10 and is located above the guide structure 40.

[0029] According to the technical solution of this embodiment, the air inlet pipe 20 is arranged at the bottom of the tower body 10, and the air outlet pipe 30 is arranged at the top of the tower body 10; the guide structure 40 is arranged inside the tower body 10 and communicated with the air inlet pipe 20. The guide structure 40 can guide the flue gas to the center of the tower body 10, and the packing structure 50 is arranged in the tower body 10 and located above the guide structure 40. Through the above arrangement, the flue gas can enter through the air inlet pipe 20 and enter the guide structure 40, and the flue gas can be guided to the center of the tower body 10 through the guide structure 40, and the flue gas is transported to the packing structure 50, and the flue gas is absorbed at the packing structure 50, and diffused from the center of the packing structure 50 to the periphery, so that the absorption effect is better. At the same time, it can prevent the flue gas from blowing the liquid onto the inner wall of the tower body 10, so that the wall flow phenomenon can be avoided. Therefore, the technical solution of this embodiment effectively solves the problem of the tower wall being easily corroded due to the wall flow phenomenon in the related art.

[0030] Specifically, by guiding the flue gas to the center of the tower body 10, the guide structure 40 increases the contact area between the flue gas and the absorbent, thereby improving the absorption rate. In practical applications, this design can significantly improve the capture efficiency, reduce the size and cost of the flue gas treatment equipment, and reduce the operating energy consumption. In large emission sources such as thermal power plants and cement plants, the use of this tower structure can achieve more efficient carbon dioxide capture, helping enterprises meet environmental protection standards and reduce carbon footprints.

[0031] like Figure 2 as well as Figures 4 to 6 As shown, in this embodiment, the flow guiding structure 40 includes a spiral tube 41, and the pitch of the spiral tube 41 gradually decreases from the bottom of the tower body 10 to the top of the tower body 10. The spiral tube 41 can effectively guide the flow and make the flow distance of the flue gas longer, so that the flue gas can be precipitated to a certain extent in the spiral tube 41, that is, the floating objects in the flue gas can be precipitated to a certain extent.

[0032] Specifically, this design enables the flue gas to form a spiral upward flow pattern when entering the tower body 10, thereby increasing the path length of the flue gas in the tower, increasing the contact time between the flue gas and the absorbent, and thus improving the capture efficiency of carbon dioxide. In the chemical, petroleum, natural gas and other industries, this design can significantly improve the performance of the treatment system and reduce environmental pollution.

[0033] Moreover, the gradually decreasing pitch design of the spiral tube 41 not only increases the residence time of the flue gas, but also promotes the turbulent mixing of the flue gas and the absorbent, thereby increasing the chemical reaction rate. In the chemical, oil and gas industries, this design can effectively reduce CO2 emissions during the production process, help enterprises comply with stricter environmental regulations, and enhance market competitiveness.

[0034] like Figure 2 as well as Figures 4 to 6 As shown, in this embodiment, the spiral tube 41 can guide the flue gas to move from the tower wall to the center position, so that the flue gas is evenly distributed in the packing structure 50. By guiding the flue gas to the center of the packing structure 50, the contact area and time between the flue gas and the absorption solution can be increased, thereby improving the absorption efficiency. The design of the spiral tube 41 can optimize the flow dynamics in the tower body 10, reduce turbulence and eddy currents, and improve the scrubbing efficiency.

[0035] like Figure 2 as well as Figures 4 to 6 As shown, in this embodiment, the tower structure further includes a flaring structure 60, which is connected to the outlet of the guide structure 40 and is located below the packing structure 50. The flaring structure 60 can diffuse the smoke, thereby making the smoke more fully contacted with the liquid in the packing structure 50.

[0036] Specifically, the expansion structure 60 can evenly diffuse the smoke from the narrow outlet of the spiral tube 41 to the filler structure 50, avoiding local overheating and excessive flow of the smoke at the filler structure 50, ensuring full contact between the smoke and the filler, and improving the absorption efficiency. In metal smelting industries such as steel and aluminum, this design can help reduce greenhouse gas emissions and meet the requirements of green production.

[0037] At the same time, the design of the expansion structure 60 not only optimizes the flue gas flow direction, but also reduces the wear of the packing structure 50 and prolongs the service life of the equipment. In metal smelting industries such as steel and aluminum, this improvement helps enterprises achieve clean production, reduce CO2 emissions, reduce maintenance costs, and improve production efficiency, which is in line with the strategic goal of sustainable development.

[0038] like Figure 2 as well as Figures 4 to 6 As shown, in this embodiment, the diameter of the expansion structure 60 gradually increases from the bottom of the tower body 10 to the top of the tower body 10. The above-mentioned setting can ensure the diffusion effect of the smoke. In addition, this design can ensure that the flow rate of the smoke gradually decreases during the rising process, increase the contact time between the smoke and the filler, and improve the absorption efficiency. In light industrial fields such as food processing and papermaking, this design can help reduce carbon dioxide emissions in the production process and enhance the environmental protection image of the enterprise.

[0039] Specifically, the gradual increase in the diameter of the expansion structure 60 helps control the flue gas flow speed and ensures that the residence time of the flue gas in the filler area is maximized, thereby improving the CO2 capture efficiency. In the food processing and papermaking industries, this design can help companies reduce greenhouse gas emissions, not only comply with environmental regulations, but also enhance the public's recognition of the company's green production image, enhance brand appeal, and promote sustainable development.

[0040] like Figure 2 as well as Figures 4 to 6 As shown, in this embodiment, the ratio between the maximum diameter of the expansion structure 60 and the diameter of the tower body 10 is between 0.3 and 0.6. The above-mentioned setting can not only ensure the diffusion effect of the smoke, but also prevent the smoke from blowing onto the inner wall of the tower body 10. At the same time, this design can ensure the best diffusion effect of the smoke at the expansion structure 60, and neither the smoke flow rate is too slow due to excessive diffusion, nor the smoke flow rate is too fast due to insufficient diffusion, thereby ensuring sufficient contact between the smoke and the filler and improving the absorption efficiency. In heavy industrial fields such as automobile manufacturing and mechanical processing, this design can help reduce carbon dioxide emissions in the production process and meet the requirements of sustainable development.

[0041] Specifically, by precisely controlling the diameter ratio of the expansion structure 60 to the tower body 10, the flow characteristics of the flue gas can be optimized to achieve efficient CO2 capture. In the automobile manufacturing and mechanical processing industries, this tower structure design can significantly reduce the greenhouse gas content in exhaust emissions, helping companies meet environmental standards, while reducing energy consumption, reducing production costs, and improving the green manufacturing level of the entire industry.

[0042] like Figures 2 to 4 as well as Figure 7 As shown, in this embodiment, the tower structure also includes a filling block 70, on which a plurality of spiral channels 71 are arranged. The filling block 70 is arranged inside the tower body 10 and above the packing structure 50. The flue gas passes through the spiral channel 71 and is discharged through the exhaust pipe 30. Since the spiral channel 71 is relatively long, the flue gas flows in the spiral channel 71 for a longer time, so that the flue gas can be cooled and the temperature of the flue gas can be prevented from being too high. In addition, this design can further increase the path length of the flue gas in the tower, prolong the contact time between the flue gas and the absorbent, and improve the absorption efficiency. In the flue gas treatment systems in the energy, chemical and other industries, this design can significantly improve the capture rate of carbon dioxide and reduce greenhouse gas emissions.

[0043] Specifically, the spiral channel 71 design on the filling block 70 not only increases the contact area between the flue gas and the absorbent, but also disperses the flue gas, avoids local hot spots, and improves the overall performance of the absorption tower. In the energy and chemical industries, this innovation can significantly reduce CO2 emissions, help companies achieve green transformation, and contribute to the global response to climate change.

[0044] like Figures 2 to 4 as well as Figure 7 As shown, in this embodiment, the plurality of spiral channels 71 include forming a plurality of spiral groups, each spiral group includes a plurality of spiral channels 71, and the plurality of spiral channels 71 are sequentially arranged in the direction from the center of the filling block 70 to the periphery of the filling block 70. The above arrangement can improve the efficiency of flue gas cooling, that is, the flue gas can be discharged from the plurality of spiral channels 71. Moreover, this design can ensure that the flow path of the flue gas in the filling block 70 is more complex, the contact area between the flue gas and the absorbent is increased, and the absorption efficiency is improved. In industries such as electricity, cement, and steel, this design can significantly improve the capture rate and capture efficiency of carbon dioxide, reduce greenhouse gas emissions, and combat global warming.

[0045] Specifically, the grouping design of the spiral channel 71 in the filling block 70 can effectively disperse the flue gas flow and increase the contact opportunity between the flue gas and the absorbent. In high-emission industries such as electricity, cement and steel, the tower structure with this design can significantly enhance the efficiency of the CO2 capture system, reduce corporate carbon emissions, and provide technical support for achieving carbon neutrality goals. At the same time, this design can also reduce the negative impact on the environment and enhance the practical effect of sustainable development.

[0046] like Figures 2 to 4 as well as Figure 7 As shown, in this embodiment, the spiral channel 71 can maximize the contact area within a limited space and improve the heat exchange efficiency. Since the spiral channel 71 does not rely on water as a cooling medium, this can reduce the consumption of water resources and reduce water treatment and maintenance costs. Since the water treatment and circulation systems are omitted, the overall cost will be relatively low. The vertical spiral channel 71 can use gravity to help the flue gas flow, reduce the energy required for pumping, and further improve energy efficiency. By optimizing the layout and materials of the spiral channel 71, the refrigeration efficiency can be improved and the required temperature control can be achieved. Since the use of water is reduced, this technology has less impact on the environment and meets the requirements of sustainable development. The vertical spiral channel 71 has a simple structure and is easy to maintain and clean, which helps to reduce long-term operating costs.

[0047] like Figures 2 to 4 as well as Figure 7 As shown, in this embodiment, the plurality of spiral groups include a first spiral group, a second spiral group and a third spiral group which are sequentially arranged in a direction from the center of the filling block 70 to the periphery of the filling block 70, and the pitch of the spiral channel 71 in the first spiral group is smaller than the pitch of the spiral channel 71 in the second spiral group. The above arrangement can ensure that the flue gas has a sufficient running distance, thereby ensuring the cooling effect of the flue gas. And this design can adjust the gas flow speed in different areas according to the flow characteristics of the flue gas to achieve a better absorption effect. In the petroleum, natural gas, chemical and other industries, this design can significantly improve the performance of the treatment system, reduce environmental pollution, and enhance the environmental protection image of the enterprise.

[0048] It should be noted that the adjustment of the pitch of different spiral groups in the filling block 70 can accurately control the flow speed of flue gas in different areas and optimize the utilization efficiency of the absorbent. In heavy industries such as oil, natural gas and chemical industry, this design improvement can significantly reduce CO2 emissions, help enterprises reduce environmental pollution and improve the overall environmental protection level of the industry. At the same time, the use of this tower structure can also enhance the social responsibility of enterprises, improve their brand image, and win more market opportunities for enterprises.

[0049] In an embodiment not shown in the figure, the absorption tower also includes heat dissipation fins, which are connected to the filling blocks 70 and extend out of the tower body 10, so that the filling blocks 70 can be effectively cooled, thereby achieving a better cooling effect on the flue gas.

[0050] like Figures 2 to 4 as well as Figure 7 As shown, in this embodiment, the absorption tower also includes a collection structure 80, which is arranged inside the tower body 10 and below the filling block 70. Condensed water will be generated after the flue gas is cooled, and the condensed water can flow from the spiral channel 71 into the collection structure. Specifically, the collection structure 80 includes a barrier film, which allows gas to pass through and prevents water from passing through. In addition, the collection structure 80 can collect unreacted absorbent, reduce resource waste, and improve the economy and environmental protection of the system. In light industrial fields such as food, pharmaceuticals, and papermaking, this design can help companies reduce production costs, improve resource utilization, and meet the requirements of green production.

[0051] Specifically, the design of the collection structure 80 can not only recycle the unreacted absorbent and reduce the consumption of raw materials, but also reduce the secondary pollution to the environment and improve the environmental performance of the entire system. In the light industrial fields such as food, pharmaceuticals and papermaking, this improvement can significantly reduce production costs and improve economic benefits. At the same time, it meets the requirements of green production, helps enterprises achieve sustainable development, improve market competitiveness, and meet consumers' growing demand for green products.

[0052] Specifically, in this embodiment, by setting an air inlet pipe 20 at the bottom of the tower body 10, setting an air outlet pipe 30 at the top of the tower body 10, and setting a guide structure 40 and a filler structure 50 inside the tower body 10, the contact efficiency between the flue gas and the absorbent is effectively improved, thereby improving the capture effect of carbon dioxide. The pitch of the spiral tube 41 is gradually reduced, so that the flue gas can be more evenly distributed to the center of the tower body 10 when entering the tower body 10, increasing the contact area between the flue gas and the filler. The setting of the flaring structure 60 further optimizes the distribution of the flue gas, prevents the local flow rate from being too fast, and ensures the full reaction of the flue gas and the absorbent. The design of the spiral channel 71 on the filling block 70 increases the complexity of the gas flow path, prolongs the residence time of the gas in the tower, and improves the absorption efficiency. The difference in the pitch of the first spiral group, the second spiral group and the third spiral group can adjust the gas flow rate in different areas according to the flow characteristics of the flue gas to achieve a better absorption effect. The setting of the collection structure 80 is helpful to collect and reuse the unreacted absorbent, reduce resource waste, and improve the economy and environmental protection of the system. The entire tower structure is reasonably designed and easy to operate. It can significantly improve the performance of the carbon dioxide capture system and has important application value in reducing greenhouse gas emissions and addressing climate change.

[0053] According to another aspect of the present application, a carbon dioxide capture system is provided. The carbon dioxide capture system of this embodiment includes a tower structure, and the tower structure is the above-mentioned tower structure. The above-mentioned tower structure can make the flue gas blow to the center of the packing structure 50, thereby avoiding the wall flow phenomenon, thereby preventing the tower body 10 from being corroded. Therefore, the carbon dioxide capture system with the above-mentioned tower structure also has the above-mentioned advantages.

[0054] Specifically, the entire tower structure is reasonably designed and easy to operate, which can significantly improve the performance of the carbon dioxide capture system and has important application value for reducing greenhouse gas emissions and responding to climate change. This tower structure is not only suitable for industrial flue gas treatment, but also can be applied to agricultural greenhouse gas emission control, carbon dioxide capture in building ventilation systems, and waste gas treatment in urban waste treatment plants, and has broad application prospects. By optimizing the contact efficiency between flue gas and absorbent, it can not only effectively reduce carbon dioxide emissions, but also reduce energy consumption and improve the overall operation efficiency of the system, which brings economic benefits to enterprises and contributes to environmental protection. Extended description: The carbon dioxide capture system adopts the above-mentioned improved tower structure, which not only has significant effects in the industrial field, but also can play an important role in many fields such as agriculture, construction and urban waste treatment, reduce greenhouse gas emissions and combat climate change. The application of this system can not only reduce the operating costs of enterprises, but also enhance the society's environmental awareness of enterprises, enhance the harmonious coexistence of enterprises and society, and contribute to the realization of global sustainable development goals. In addition, the system can also promote technological innovation in related industries and promote the development of the green economy.
