Description

Technical Field

[0001] This invention relates to the field of flue gas treatment technology, and in particular to a flue gas treatment system. Background Technology

[0002] The large amounts of flue gas generated by factories need to be treated and purified before being discharged. Equipment used to treat flue gas is generally called a tower, such as a desulfurization tower or an absorption tower. The main method of flue gas treatment is to spray a reaction solution inside the tower, and use the gas-liquid reaction between the solution and the flue gas to absorb substances in the flue gas. For example, alkaline solutions are used to absorb sulfides in flue gas, and organic amine solutions are used to absorb carbon dioxide in flue gas.

[0003] Existing flue gas reactors are generally quite tall, making them prone to problems when subjected to lateral loads (such as those from strong winds or earthquakes). Therefore, improving the structural stability of flue gas reactors is one of the design requirements for flue gas treatment. Summary of the Invention

[0004] One object of the present invention is to provide a flue gas treatment system that can improve the structural stability of a flue gas reaction tower.

[0005] Specifically, the present invention provides a flue gas treatment system, comprising:

[0006] Two flue gas reaction towers, the internal space of which is used to receive and process flue gas, are arranged facing each other with the same sides; and

[0007] Multiple connecting structures are disposed between the opposite sides of the two flue gas reaction towers, and each connecting structure is fixedly connected to the two flue gas reaction towers respectively.

[0008] Optionally, the connection structure includes multiple sets of connection components. Each set of connection components includes a connecting beam and two support beams. The two ends of the connecting beam are fixedly connected to the two flue gas reaction towers, respectively. The two support beams are disposed at the bottom of the connecting beam and are located at the two ends of the connecting beam, respectively. One end of each support beam is fixedly connected to the flue gas reaction tower, and the other end is fixedly connected to the connecting beam.

[0009] Optionally, multiple connecting structures are distributed longitudinally, and the maintenance opening of the flue gas reaction tower is located on the side fixed to the connecting structure and above one of the connecting structures, and the distance between the opening and the corresponding connecting structure is less than 1 meter.

[0010] The connection structure corresponding to the maintenance opening is equipped with a maintenance platform.

[0011] Optionally, the flue gas reaction tower includes a main body, which includes multiple assembly modules, each of which is cylindrical, and the multiple assembly modules are fixedly connected longitudinally to form the main body.

[0012] Optionally, the flue gas reaction tower further includes a reinforcing frame that surrounds the main body of the equipment and is fixedly connected to the main body of the equipment.

[0013] Optionally, the connection structure is fixedly connected to the reinforcing frame.

[0014] Optionally, the flue gas reaction tower further includes at least one diversion device, which is disposed inside the flue gas reaction tower to divide the internal space of the flue gas reaction tower into multiple flue gas treatment areas distributed longitudinally.

[0015] The diversion device includes multiple liquid receiving tanks for receiving liquid from above, the multiple liquid receiving tanks being arranged at intervals such that an airflow channel is formed between the sidewalls of two adjacent liquid receiving tanks; and

[0016] A shielding structure is disposed above the flow channel to prevent liquid from above the diversion device from entering the flow channel, and the shielding structure has a gap with the sidewall of at least one of the two adjacent liquid receiving tanks, so that gas below the diversion device can flow through the flow channel to the top of the diversion device.

[0017] Optionally, each airflow channel corresponds to one shielding structure, the shielding structure is curved, the concave surface of the shielding structure faces the airflow channel, and the highest point of the shielding structure is aligned with the airflow channel in the vertical direction.

[0018] Optionally, the flue gas treatment system further includes two cooling devices, which are respectively installed on the side walls of the two flue gas reaction towers opposite to the connecting structure. The cooling devices form a longitudinal cooling air path to cool the internal space of the flue gas reaction towers through the airflow flowing through the cooling air path, thereby improving the gas-liquid reaction efficiency.

[0019] Optionally, the bottom surface of the cooling device is flush with the bottom surface of the flue gas reaction tower.

[0020] The flue gas treatment system of the present invention arranges two flue gas reaction towers facing each other on the same side, and sets up multiple connecting structures between the opposing sides of the two flue gas reaction towers, thereby fixing the two flue gas reaction towers together and enabling them to support each other, which helps to improve the structural stability of the flue gas reaction towers and thus improve their resistance to lateral loads. Furthermore, the two flue gas reaction towers receive and treat flue gas separately. In this way, even if one flue gas reaction tower fails, the other flue gas reaction tower can continue to operate, ensuring the continuity of flue gas treatment to a certain extent and reducing the occurrence of interruptions in flue gas treatment.

[0038] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can also refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0039] like Figure 1 As shown, in one embodiment, the flue gas treatment system includes two flue gas reaction towers 100 and a plurality of connecting structures 200. The internal space of the flue gas reaction towers 100 is used to receive and process flue gas. The two flue gas reaction towers 100 are arranged opposite each other with the same sides facing each other. The plurality of connecting structures 200 are disposed between the opposite sides of the two flue gas reaction towers 100, and each connecting structure 200 is fixedly connected to the two flue gas reaction towers 100 respectively.

[0040] Reference Figures 1 to 2 As shown, specifically, the flue gas reaction tower 100 is cuboid in shape, and the two flue gas reaction towers 100 are arranged symmetrically with respect to the longitudinal plane, with identical sides of the two flue gas reaction towers 100 facing each other. That is, the identical square faces of the two flue gas reaction towers 100 are arranged opposite each other. The connecting structure 200 is disposed between the opposite sides of the two flue gas reaction towers 100 and is fixedly connected to the two flue gas reaction towers 100 respectively, thereby fixing the two flue gas reaction towers 100 together.

[0041] like Figures 1 to 4 As shown, the connection structure 200 includes multiple sets of connection components 210. Each set of connection components 210 includes a connecting beam 211 and two support beams 212. The two ends of the connecting beam 211 are fixedly connected to the two flue gas reaction towers 100 respectively. The two support beams 212 are located at the bottom of the connecting beam 211 and at the two ends of the connecting beam 211 respectively. One end of each support beam 212 is fixedly connected to the flue gas reaction tower 100, and the other end is fixedly connected to the connecting beam 211.

[0042] Continue to refer to Figures 1 to 4 As shown, specifically, the connecting beam 211 extends along the distribution direction of the two flue gas reaction towers 100, with one end fixedly connected to one of the flue gas reaction towers 100 and the other end fixedly connected to the other flue gas reaction tower 100. The connecting beams 211 of each set of connecting components 210 are distributed horizontally. Support beams 212 of the connecting components 210 are located at the bottom of the connecting beams 211 and at both ends of the connecting beams 211. One end of the support beam 212 is fixedly connected to the flue gas reaction tower 100, and the other end is fixedly connected to the bottom surface of the connecting beam 211, thus forming a triangle with the flue gas reaction tower 100 and the connecting beam 211 at the end of the connecting beam 211, enhancing structural stability. Multiple connecting structures 200 are distributed longitudinally, thus forming more connections both longitudinally and laterally, improving the robustness of the connection between the two flue gas reaction towers 100.

[0043] It should be noted that the two flue gas reaction towers 100 are configured such that the sum of their processing efficiencies meets the preset processing efficiency.

[0044] In this embodiment, by arranging two flue gas reaction towers 100 facing each other on the same side and providing multiple connecting structures 200 between the opposing sides of the two flue gas reaction towers 100, the two flue gas reaction towers 100 can be fixed together, allowing them to support each other. This helps improve the structural stability of the flue gas reaction towers 100, thereby increasing their resistance to lateral loads. Furthermore, since the two flue gas reaction towers 100 receive and treat flue gas respectively, even if one flue gas reaction tower 100 fails, the other flue gas reaction tower 100 can continue to operate, ensuring the continuity of flue gas treatment to a certain extent and reducing the occurrence of interruptions in flue gas treatment.

[0045] It should be noted that in some other embodiments, the connection structure may also be distributed laterally, with each set of connection components in each connection structure distributed longitudinally. Alternatively, the connection structure may be a plate-like structure, with opposite sides of the plate fixedly connected to the two flue gas reaction towers respectively.

[0046] like Figures 1 to 4 As shown, in one embodiment, the maintenance opening 101 of the flue gas reaction tower 100 is located on a side wall fixed to the connecting structure 200 and positioned above one of the connecting structures 200, with a distance of less than 1 meter from the corresponding connecting structure 200. The connecting structure 200 is provided with a maintenance platform 220 for supporting maintenance personnel.

[0047] Reference Figures 1 to 4 As shown, the maintenance platform 220 is a flat structure that is positioned above and fixedly connected to multiple horizontally distributed connecting beams 211. The maintenance opening 101 is located above the connecting structure 200, that is, above the maintenance platform 220, allowing maintenance personnel to perform external maintenance on the flue gas reactor 100 from the maintenance platform 220, or to enter the flue gas reactor 100 from the maintenance platform 220 through the maintenance opening 101 to perform internal maintenance on the flue gas reactor 100.

[0048] In this embodiment, the maintenance opening 101 of the flue gas reactor 100 is located on the side wall fixed to the connecting structure 200 and above one of the connecting structures 200, with a distance of less than 1 meter from the corresponding connecting structure 200. A maintenance platform 220 is provided on the connecting structure 200, which can support maintenance personnel. This facilitates maintenance personnel to inspect both flue gas reactors 100 and allows them to enter the flue gas reactor 100 through the maintenance opening 101 to inspect its interior, thus improving the convenience of maintenance of the flue gas reactor 100.

[0049] It should be noted that the distance between the two flue gas reaction towers 100 facing each other should be greater than or equal to 0.6 meters and less than or equal to 10 meters. For example, it can be 0.6 meters, 0.8 meters, 1 meter, 1.1 meters, 1.5 meters, 2 meters, 2.1 meters, 2.5 meters, 3 meters, 3.1 meters, 3.5 meters, 4 meters, 4.1 meters, 4.5 meters, 5 meters, 5.1 meters, 5.5 meters, 6 meters, 6.1 meters, 6.5 meters, 7 meters, 7.1 meters, 7.5 meters, 8 meters, 8.1 meters, 8.5 meters, 9 meters, 9.1 meters, 9.5 meters, or 10 meters. This provides sufficient space for maintenance personnel while avoiding excessive cost for the connection structure 200.

[0050] like Figure 1 and Figure 2 , Figures 5 to 6 As shown, in one embodiment, the flue gas reaction tower 100 includes a main body 110, which includes a base 111 and multiple assembly modules 112. Each assembly module 112 is cylindrical, and the multiple assembly modules 112 are fixedly connected longitudinally to form the main body 110. Specifically, the base 111 is a cuboid structure with an open top. The base 111 constitutes the bottommost part of the flue gas reaction tower 100, which can contact the ground to support the flue gas reaction tower 100. The sidewall of the base 111 also forms a flue gas inlet for receiving flue gas, thereby allowing the flue gas to enter the internal space of the flue gas reaction tower 100 and flow from the bottom to the top of the flue gas reaction tower 100.

[0051] Reference Figure 5 and Figure 6 As shown, each assembly module 112 has four side walls, forming a rectangular structure open at both ends. Multiple assembly modules 112 are fixedly connected longitudinally, so that the areas they enclose are joined together to form a continuous space in the longitudinal direction. The bottom assembly module 112 is connected to the base 111 to connect to the internal space of the base 111. The flue gas reaction tower 100 also includes an exhaust structure 120, which covers the top of the top assembly module 112, for guiding and exhausting the treated flue gas within the flue gas reaction tower 100.

[0052] In this embodiment, multiple assembly modules 112 are fixedly connected to form part of the main body 110 of the equipment. This means that during the construction of the flue gas reaction tower 100, the towers are continuously stacked and raised, thereby improving the ease of construction. Furthermore, the connecting structure 200 can be installed when the required height is reached, which is more convenient than installing the connecting structure 200 on the outside of two complete flue gas reaction towers 100.

[0053] It should be noted that the main body of the equipment is made of steel.

[0054] like Figure 5 and Figure 6 As shown, the flue gas reaction tower 100 also includes a reinforcing frame 130, which surrounds the main body 110 and is fixedly connected to it. Specifically, the reinforcing frame 130 is composed of multiple horizontal and vertical bars. On each side of the main body 110, the horizontal and vertical bars of the reinforcing frame 130 form a grid structure, and the horizontal bars on each side are connected at the adjacent points of adjacent sides of the equipment to 110, thereby forming the reinforcing frame 130 surrounding the main body 110.

[0055] Those skilled in the art will understand that by providing a reinforcing frame 130 around the main body 110 of the equipment, the connection between the assembly modules 112 can be further strengthened, the overall structural stability of the flue gas reaction tower 100 can be improved, thereby improving the overall structural stability of the flue gas treatment system composed of the connecting structure 200 and the two flue gas reaction towers 100.

[0056] like Figures 1 to 5 As shown, the connecting structure 200 is fixedly connected to the reinforcing frame 130. Specifically, the connecting beam 211 and support beam 212 of each set of connecting components 210 are fixedly connected to the longitudinal rods in the reinforcing frame 130. By fixing the connecting structure 200 to the reinforcing frame 130, the force transmitted by the connecting structure 200 can be distributed throughout the entire reinforcing frame 130, improving the resistance of the flue gas treatment system to external forces.

[0057] like Figures 7 to 10 As shown, taking a flue gas reaction tower 100 as an example, the flue gas reaction tower 100 also includes multiple diversion devices 140. The diversion devices 140 are disposed inside the flue gas reaction tower 100 and are used to divide the internal space of the flue gas reaction tower 100 into multiple flue gas treatment areas distributed longitudinally. The diversion device 140 includes multiple liquid receiving tanks 141 for receiving liquid from above. The multiple liquid receiving tanks 141 are arranged at intervals, such that a flow passage 1401 is formed between the sidewalls of two adjacent liquid receiving tanks 141. The diversion device 140 also includes a shielding structure 142 disposed above the flow passage 1401. The shielding structure 142 is used to prevent liquid from above the diversion device 140 from entering the flow passage 1401, and the shielding structure 142 has a gap with the sidewall of at least one of the two adjacent liquid receiving tanks 141, so that the gas below the diversion device 140 can flow through the flow passage 1401 to the top of the diversion device 140.

[0058] Reference Figures 7 to 10As shown, specifically, multiple liquid receiving tanks 141 are arranged side by side in the same direction of extension, and there is a gap between the side walls of two adjacent liquid receiving tanks 141, which are the air passages 1401. Each air passage 1401 is provided with a shielding structure 142 above it, that is, one air passage 1401 corresponds to one shielding structure 142. The shielding structure 142 covers the air passage 1401 in the vertical direction and has gaps with the side walls of the liquid receiving tanks 141 on both sides.

[0059] Reference Figures 7 to 10 As shown, the diversion device 140 has a flue gas treatment zone above and below it. The diversion device 140 allows gas flow from its lower gas treatment zone to its upper gas treatment zone, but prevents liquid from flowing from its upper gas treatment zone to its lower gas treatment zone. In this way, after the gas enters the flue gas reaction tower 100 from the bottom, it flows from bottom to top, passing through each gas treatment zone sequentially, where independent gas-liquid reactions occur. Finally, the gas is discharged from the top of the flue gas reaction tower 100, thus completing multiple gas treatment processes within the flue gas reaction tower 100.

[0060] Reference Figure 10 The dashed arrow illustrates the gas flow path. Specifically, gas below the diversion device 140 can flow through the gap between the airflow channel 1401 and the sidewall of the shielding structure 142 and the liquid receiving tank 141 to the top of the diversion device 140. (Refer to...) Figure 5 The solid arrows indicate the liquid flow path. The liquid sprayed above the diversion device 140 (desulfurization solution or decarbonization solution, etc.) can fall directly into the receiving tank 141 or onto the shielding structure 142, and then flow along the shielding structure into the receiving tank 141. When gas flows above the diversion device 140, it can react with the liquid sprayed above the diversion device 140, while the liquid sprayed above the diversion device 140 will not fall into the area below the diversion device 140, allowing different gas treatment processes to be carried out in the areas above and below the diversion device 140.

[0061] For example, the flue gas reaction tower 100 can be divided into three gas treatment zones by two diversion devices 140, which are, from bottom to top, a desulfurization zone, a carbon capture zone, and a purification zone. Specifically, the flue gas undergoes desulfurization treatment in the desulfurization zone, and then enters the carbon capture zone through the diversion device 140 between the desulfurization zone and the carbon capture zone. A decarbonization solution is sprayed in the carbon capture zone to decarbonize the flue gas. The sprayed decarbonization solution falls onto the diversion device 140 between the desulfurization zone and the carbon capture zone, and does not fall into the desulfurization zone, thus avoiding any impact on the desulfurization process. The decarbonized flue gas continues to flow upwards, passing through the diversion device 140 between the carbon capture zone and the purification zone to enter the purification zone. The purification zone uses electrostatic dust removal to absorb the dispersed medium in the flue gas. The adsorbed droplets fall onto the diversion device 140 between the carbon capture zone and the purification zone, and do not fall into the carbon capture zone, thus avoiding any impact on the decarbonization process.

[0062] It should be noted that one, two, three, four, or more diversion devices can be installed within the flue gas reaction tower. Furthermore, with a sufficient number of gas processing zones, multiple adjacent gas processing zones can be used to perform the same gas processing flow. For example, three diversion devices can be installed within the flue gas reaction tower, dividing the reaction space into four gas processing zones: from bottom to top, one desulfurization zone, two carbon capture zones, and one purification zone.

[0063] In this embodiment, a diversion device 140 is installed inside the flue gas reaction tower 100. The diversion device 140 has multiple liquid receiving tanks 141, and a flow passage 1401 is formed between the sidewalls of two adjacent liquid receiving tanks 141. A shielding structure 142 is installed above the flow passage 1401, which can cover the flow passage 1401. In this way, the liquid sprayed in the area above the diversion device 140 will fall directly into the liquid receiving tank 141 or onto the shielding structure 142 and then flow into the liquid receiving tank 141, without falling into the area below the diversion device 140. However, the gas in the area below the diversion device 140 can flow to the area above the diversion device 140 through the gap between the flow passage 1401 and the shielding structure 142 and the sidewall of the liquid receiving tank 141. In other words, different gas-liquid reactions can occur in the area above and below the diversion device 140, that is, different gas-liquid treatment processes can be carried out in the flue gas reaction tower 100. Therefore, by using two flue gas reaction towers 100 to construct the flue gas treatment system and improving the structural stability of the flue gas reaction towers 100, each flue gas reaction tower 100 can complete all the required flue gas treatment processes, thus not increasing the number of towers required for the entire flue gas treatment process (because even if multiple flue gas treatment processes use a single tower, multiple towers still need to be built). This increases the structural stability of the flue gas reaction towers 100 without excessively increasing the footprint and cost of the flue gas treatment system.

[0064] like Figures 8 to 10 As shown, the shielding structure 142 is a smooth curved surface, meaning both its convex and concave surfaces are smooth curved surfaces. The concave surface of the shielding structure 142 faces the airflow channel 1401, and the highest point of the shielding structure 142 is aligned with the airflow channel 1401 in the vertical direction. Specifically, the highest point of the shielding structure 142 is aligned with the airflow channel 1401 in the vertical direction, meaning that the convex surface of the shielding structure 142 slopes from high to low towards the liquid receiving tanks 141 on both sides.

[0065] Those skilled in the art will understand that by setting the shielding structure 142 to a smooth curved surface, with the concave surface of the shielding structure 142 facing the flow channel 1401, and the highest point of the shielding structure 142 aligned vertically with the flow channel 1401, the gas from the flow channel 1401 can flow to both sides under the guidance of the concave surface of the shielding structure 142, improving the uniformity of gas distribution and contributing to improved gas-liquid reaction efficiency. Furthermore, liquid falling onto the convex surface of the shielding structure 142 can flow to the liquid receiving tanks 141 on both sides under the guidance of the convex surface of the shielding structure 142, preventing liquid accumulation in the shielding structure 142 and reducing the likelihood of liquid droplets splashing into the flow channel 1401.

[0066] It should be noted that in some other embodiments, the shielding structure may also be a curved structure with angles, such as an acute angle, a right angle, or an obtuse angle, with the highest point, i.e., the angle, aligned with the airflow channel. Additionally, in some other embodiments, the shielding structure may also be a planar plate structure.

[0067] Additionally, it should be noted that in some other embodiments, the shielding structure can also be a complete plate-like structure that covers all airflow channels and has through holes aligned with the liquid receiving tank in the vertical direction.

[0068] It should be noted that, in some embodiments, the diversion device may also include a liquid collection container, with all liquid receiving tanks fixedly connected to and communicating with the liquid collection container, so that liquid falling into the liquid receiving tanks flows into the liquid collection container and is collected.

[0069] It should be noted that the diversion device may not require a collection container; multiple receiving tanks can be directly fixed to the plate-like structure and then to the side wall of the reaction equipment, or they can be directly fixed to the side wall of the reaction equipment. Simultaneously, a pump system is used to extract the liquid from the receiving tanks.

[0070] like Figures 11 to 13 As shown, in one embodiment, when a shielding structure 142 is provided in each airflow channel 1401, the shielding structure 142 is fixedly connected to the sidewall of one of the two adjacent liquid receiving tanks 141, and has a gap with the sidewall of the other. Specifically, it can also be said that for two adjacent sidewalls of two liquid receiving tanks 141, the top of the sidewall of one liquid receiving tank 141 extends toward the sidewall of the other liquid receiving tank 141 to form a shielding structure 142 covering the airflow channel 1401.

[0071] Reference Figure 13 The dashed arrow illustrates the gas flow path. Specifically, the gas below the diversion device 140 can flow through the airflow channel 1401 to the shielding structure 142. Because the shielding structure 142 is fixedly connected to the side wall of a liquid receiving tank 141, the gas can only flow towards the side wall of another liquid receiving tank 141 that has a gap with the shielding structure 142, and finally flows above the diversion device 140. (Refer to...) Figure 13The solid arrows indicate the liquid flow path. The liquid sprayed above the diversion device 140 (desulfurization solution or decarbonization solution, etc.) can fall directly into the receiving tank 141 or onto the shielding structure 142, and then flow along the shielding structure into the receiving tank 141. When gas flows above the diversion device 140, it can react with the liquid sprayed above the diversion device 140, while the liquid sprayed above the diversion device 140 will not fall into the area below the diversion device 140, allowing different gas treatment processes to be carried out in the areas above and below the diversion device 140.

[0072] Reference Figure 1 and Figure 7 As shown, the flue gas treatment system also includes two cooling devices 300. The two cooling devices 300 are respectively installed on the side walls opposite to the connecting structure 200 of the two flue gas reaction towers 100. The cooling devices 300 form a longitudinal cooling air passage 301 to cool the internal space of the flue gas reaction tower 100 through the airflow flowing through the cooling air passage 301, so as to improve the gas-liquid reaction efficiency.

[0073] Reference Figure 1 and Figure 7 As shown, specifically, the cooling device 300 is attached to the side wall of the flue gas reaction tower 100 opposite to the connecting structure 200, so as to... Figure 1 As shown in the plan, a connecting structure 200 is connected to the right side of the flue gas reaction tower on the left, and a cooling device 300 is located on its left side. The cooling device 300 has an air outlet at the top that communicates with the cooling air passage 301, and an air inlet at the bottom that communicates with the cooling air passage 301. A fan (not shown in the figure) is installed inside the cooling air passage. By starting the fan, air is driven into the cooling air passage 301 through the air inlet and flows out of the cooling air passage 301 through the air outlet, forming a continuous cooling airflow within the cooling air passage 301. This airflow cools the flue gas reaction tower 100 through heat conduction with the side wall of the flue gas reaction tower 100, thereby improving the reaction efficiency of the flue gas and the reaction solution inside the flue gas reaction tower 100.

[0074] Reference Figure 1 and Figure 7 As shown, the bottom surface of the cooling device 300 is flush with the bottom surface of the flue gas reaction tower 100, meaning that the bottom surfaces of the cooling device 300 and the flue gas reaction tower 100 are supported on the ground together. Since the cooling device 300 is also fixedly connected to the flue gas reaction tower 100, it can not only cool the flue gas reaction tower 100, but also increase the support area through the overall structure formed by the flue gas reaction tower 100 and the cooling device 300, thereby making the entire flue gas treatment system more stable. Moreover, the cooling device 300 is attached to the side wall of the flue gas reaction tower 100 opposite to the connecting structure 200, so it can enhance the bearing capacity of the connecting structure 200 when the flue gas treatment system is subjected to lateral loads.

[0075] In addition, a reinforcing frame is also provided on the outside of the cooling equipment 300, and it is fixedly connected to the reinforcing frame on the outside of the flue gas reaction tower 100.

[0076] Reference Figure 1 and Figure 7 As shown, specifically, the cooling equipment 300 is also equipped with a cooling pool at its bottom for holding cold water. A spray device is installed in the cooling air passage 301, which sprays the cold water from the cooling pool into the cooling air passage 301, thereby further cooling the airflow and improving the cooling effect on the flue gas reaction tower 100, thus further improving the reaction efficiency within the flue gas reaction tower 100. Furthermore, the cooling pool holding cold water increases the gravity of the cooling equipment 300, thereby further improving the stability of the flue gas treatment system.
