Description

Technical Field

[0001] The utility model relates to the technical field of flue gas treatment, in particular to a gas-liquid mixing device and a flue gas treatment device. Background Art

[0002] Some industrial production processes are accompanied by the generation of large amounts of flue gas, which needs to be treated and purified before discharge. Currently, flue gas is usually treated by a gas-liquid reaction in a reaction tower. Generally speaking, the flue gas is introduced into the reaction tower from the bottom, and a reaction solution (such as a desulfurization solution, a decarbonization solution, etc.) that reacts with the flue gas is sprayed into the reaction tower. As the flue gas flows upward, it reacts with the reaction solution, thereby eliminating environmentally harmful components in the flue gas and achieving the purpose of flue gas purification.

[0003] To improve the efficiency of the gas-liquid reaction in the reaction tower, packing is usually placed inside the reaction tower to provide a contact surface for the gas and liquid, thereby increasing the gas-liquid contact area. However, existing packings are all the same size as the circumference of the reaction tower, which is bulky and inconvenient to use. Utility Model Content

[0011] Optionally, the separator includes two sealing films, which are respectively arranged on both sides of the square frame and cover the area enclosed by the square frame. The sealing films are sealed and fitted with four sides of the square frame to prevent gas from passing through the square frame.

[0013] Optionally, the lowest points on both sides of the top surface of the partition between two adjacent filler pieces are higher than or flush with the top surfaces of the filler pieces.

[0014] In another aspect of the present invention, a flue gas treatment device is provided, comprising:

[0015] a reaction device forming a reaction space; and

[0016] At least one gas-liquid mixing device according to any one of the above items, wherein the gas-liquid mixing device is arranged in the reaction space.

[0017] Optionally, the reaction space is cube-shaped, the filler pieces are cube-shaped, and along the distribution direction of the multiple filler pieces, the end faces of the filler pieces at the two ends are sealed with the inner wall of the reaction space, and along the direction perpendicular to the distribution direction of the multiple filler pieces, the side faces of the multiple filler pieces are sealed with the inner wall of the reaction space.

Moreover, compared with the use of a large-volume filler element, there is a situation where the filler element must be replaced or removed for cleaning if part of it is damaged or needs to be cleaned.

In addition, the multiple filler elements can be supported in the vertical direction by the support members and fixed in position in the horizontal direction by the partition members, making the overall structure of the gas-liquid mixing device more stable and improving the firmness of the installation of the gas-liquid mixing device.

[0042] Furthermore, it should be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0043] like Figures 1 to 3 As shown, in one embodiment, the flue gas treatment device 10 includes a reaction device 100 and a gas-liquid mixing device 200. The reaction device 100 forms a reaction space 101. The gas-liquid mixing device 200 is disposed in the reaction space 101.

[0044] Combine Figures 1 to 5 As shown, in one embodiment, a gas-liquid mixing device 200 includes a mounting frame 210 and a filler 220. The mounting frame 210 includes a transverse support member 211 and a plurality of partitions 212 extending upward from the top surface of the support member 211. The plurality of partitions 212 are spaced apart in the transverse direction to define a plurality of placement areas 201. Each placement area 201 is formed with a through hole extending longitudinally through the support member 211. The filler 220 is disposed in the placement area 201, abutting against the partition 212.

[0045] like Figures 4 to 7 As shown, specifically, the support member 211 includes a plurality of laterally distributed grid plates 2111, the partition 212 is arranged between two adjacent grid plates 2111, and two assembly grooves 2121 are provided at the bottom of each partition 212, and the openings of the two assembly grooves 2121 are respectively facing the opposite sides of the partition 212, and the grid plates 2111 on both sides of the partition 212 respectively extend into the assembly grooves 2121.

[0046] Reference Figures 4 to 7As shown, the mesh panels 2111 have a square outline and can be considered to be formed by punching multiple square holes through a square panel. The square holes in the mesh panels 2111 are the aforementioned through-holes that extend longitudinally through the support member 211. The multiple mesh panels 2111 are arranged in the same direction as the multiple dividers 212, and are arranged in a cyclic pattern, one mesh panel 2111 per divider 212, such that the dividers 212 are positioned between two adjacent mesh panels 2111. In other words, the area above each mesh panel 2111 is the placement area 201 separated by the dividers 212.

[0047] Continue to refer to Figures 4 to 7 As shown, along the distribution direction of the multiple dividers 212, the bottom of each divider 212 is provided with a mounting groove 2121 that opens toward two opposite sides. In other words, the openings of the two mounting grooves 2121 face the grid plates 2111 on either side. Specifically, the mounting groove 2121 comprises a longitudinal wall and two transverse walls, which extend in the vertical direction. Alternatively, the bottom of the divider 212 forms an "I"-shaped structure. The grid plates 2111 extend into the mounting groove 2121 and rest on the transverse walls at the bottom.

[0048] Reference Figures 1 to 4 As shown, the filler member 220 is generally in the shape of a cube. The filler member 220 is disposed in the placement area and abuts against at least one partition 212, so that the filler member 220 can be supported longitudinally by the support member 211 and fixed in position transversely by the partition 212. Furthermore, the distribution direction of the multiple filler members 220, the distribution direction of the multiple partitions 212, and the distribution direction of the multiple grid plates 2111 are all the same. In a direction perpendicular to the distribution direction of the multiple filler members 220, the dimensions of the filler members 220, the dimensions of the partitions 212, and the dimensions of the grid plates 2111 are the same. Furthermore, the two ends of the gas-liquid mixing device 200 along the distribution direction of the multiple filler members 220 are filler members 220, so that the gas-liquid mixing device 200 as a whole is roughly a cube. That is, for the gas-liquid mixing device 200 as a whole, the four side surfaces are the end surfaces of the filler members 220 at the two ends and the side surfaces composed of the side surfaces of the multiple filler members 220 and the partition 212.

[0049] It can be understood by those skilled in the art that the filler has a hollow area for gas and liquid to pass through, so that gas-liquid reaction occurs on the solid part of the filler, that is, the contact surface provided by the filler. The filler piece 220 of this embodiment is only square in shape, and the rest of the structure can be set with reference to the existing filler.

[0050] like Figures 1 to 4As shown, specifically, the reaction space 101 is a cube, the filler pieces 220 are a cube, and along the distribution direction of the multiple filler pieces 220, the end faces of the filler pieces 220 at the two ends are sealed with the inner wall of the reaction space 101, and along the direction perpendicular to the distribution direction of the multiple filler pieces 220, the side faces of the multiple filler pieces 220 are sealed with the inner wall of the reaction space 101.

[0051] Reference Figures 1 to 4 As shown, the reaction device 100 is a cube, thereby forming a cube-shaped reaction space 101. The gas-liquid mixing device 200 is fixedly connected to the reaction device 100 by a mounting frame 210. Along the direction perpendicular to the distribution direction of the plurality of filler members 220, the size of the filler members 220, the size of the separator 212 and the size of the grid plate 2111 are the same as the size of the reaction space 101, so that the two side surfaces of the gas-liquid mixing device 200 distributed along the direction perpendicular to the distribution direction of the plurality of filler members 220 can be sealed and fitted with the inner wall of the reaction space 101. In addition, along the distribution direction of the plurality of filler members 220, the size of the gas-liquid mixing device 200 as a whole is the same as the size of the reaction space 101, so that the end faces of the filler members 220 at the two ends are sealed and fitted with the inner wall of the reaction space 101.

[0052] Continue to refer to Figures 1 to 4 As shown, the flue gas treatment device 10 also includes a spray device 300 corresponding to each gas-liquid mixing device 200. The spray device 300 is disposed within the reaction space 101 and above the corresponding gas-liquid mixing device 200. An air inlet is provided at the bottom side of the reaction apparatus 100 to receive the flue gas to be treated. After entering the reaction space 101, the flue gas flows from the bottom to the top, passing through the gas-liquid mixing device 200. Specifically, it enters and passes through the packing 220 via the mesh holes in the mesh plate 2111. Simultaneously, the spray device 300 sprays a reaction solution into the reaction space 101. The reaction solution lands on the packing 220 and diffuses on its surface. The gas and reaction solution come into contact on the surface of the packing 220, causing a gas-liquid reaction. Of course, direct contact between the upward-flowing flue gas and the falling reaction solution can also produce a certain gas-liquid reaction. Ultimately, the treated flue gas continues to flow upward and exits the top of the flue gas treatment device 10.

[0053] In the solution of this embodiment, by providing a mounting frame 210 composed of transverse support members 211 and longitudinal partitions 212, multiple placement areas for the filler members 220 can be separated, allowing multiple filler members 220 to be fixed to the mounting frame 210 in a distributed manner along the transverse direction. In other words, in the transverse direction, multiple filler members 220 collectively fill the reaction space 101 of the reaction apparatus 100. Therefore, while achieving improved gas-liquid reaction efficiency, the volume of a single filler member 220 is effectively reduced, making the installation, replacement, and cleaning of the filler member 220 more convenient, effectively improving the ease of use of the filler member 220. Moreover, compared to the use of a single, large filler member, which may require replacement or removal for cleaning if part of the filler member is damaged or requires cleaning, when multiple filler members 220 are arranged transversely, each filler member 220 can be replaced or cleaned individually according to its usage, effectively saving work time and material costs. In addition, the plurality of filler members 220 can be supported longitudinally by the support member 211 and fixed in position transversely by the partition member 212, so that the overall structure of the entire gas-liquid mixing device 200 is more stable and the installation firmness of the gas-liquid mixing device 200 is improved.

[0054] Furthermore, by configuring the support member 211 as a plurality of laterally distributed grid plates 2111 and providing two assembly grooves 2121 at the bottom of the partition 212, the grid plates 2111 on both sides of the partition 212 are respectively extended into the assembly grooves 2121. Compared with the use of a complete large support member, the positioning work of the plurality of partitions 212 on the support member is reduced, and the cooperation between the assembly grooves 2121 and the grid plates 2111 is also convenient for fixation, thereby making the production of the mounting frame 210 more convenient.

[0055] In addition, by setting the reaction space 101 to be square-shaped and the filler member 220 to be square-shaped, the gas-liquid mixing device 200 can better cooperate with the inner wall of the reaction space 101, and it is also convenient to seal the gas-liquid mixing device 200 with the inner wall of the reaction space 101, making the installation of the gas-liquid mixing device 200 in the reaction space 101 more convenient.

[0056] It should be noted that, in some other embodiments, the support member may be a larger, integral plate with holes. Furthermore, in some other embodiments, the filler member and the reaction space may have other mutually compatible shapes. Furthermore, in some other embodiments, each filler member may be clamped between two spacers.

[0057] It should be noted that the flue gas treatment device may have one, two, three or more gas-liquid mixing devices.

[0058] like Figures 4 to 7As shown, in one embodiment, the partition 212 includes a square frame 2122, the bottom side frame edge of the square frame 2122 is connected to the support member 211, and the filler member 220 abuts against the side surface of the square frame 2122. Specifically, the square frame 2122 is formed by four I-beams connected end to end. The two grooves of the I-beams serving as the bottom side frame edge constitute the aforementioned assembly grooves 2121, that is, the bottom side frame edge is connected to the support member 211.

[0059] In the solution of this embodiment, by using the square frame 2122 as the partition 212, the filler 220 can be stably abutted, while the structure of the partition 212 is simplified and the cost is reduced.

[0060] like Figure 7 As shown, the separator 212 further includes at least two reinforcing rods 2123 disposed inside the square frame 2122. The two ends of the reinforcing rods 2123 are fixedly connected to the top and bottom side edges of the square frame 2122, respectively. Two adjacent reinforcing rods 2123 form a triangle with the bottom or top side edges of a portion of the square frame 2122. Specifically, the reinforcing rods 2123 are disposed within the square area enclosed by the square frame 2122 and are tilted. The two ends of the reinforcing rods 2123 are fixedly connected to the top and bottom side edges of the square frame 2122, respectively. Adjacent reinforcing rods 2123 have opposite tilt directions, thereby forming a triangle with the bottom or top side edges of the portion of the square frame 2122. The provision of the reinforcing rods 2123 helps improve the structural stability of the separator 212.

[0061] Reference Figure 7 and Figure 8 As shown, in one embodiment, the separator 212 includes two sealing films 2124, which are respectively disposed on either side of the square frame 2122 and cover the area enclosed by the square frame 2122. The sealing films 2124 are in sealed contact with the four sides of the square frame 2122 to prevent gas from passing through the square frame 2122. In other words, after the flue gas enters the packing member through the through hole in the support member, it can only continue to flow upward within the packing member and will not flow upward into the area enclosed by the square frame 2122. This ensures that the flue gas flows within the packing member while passing through the gas-liquid mixing device, thereby ensuring good reaction efficiency between the flue gas and the reaction solution.

[0062] It should be noted that, in some other embodiments, the separator may also be a solid or hollow plate structure.

[0063] like Figure 9As shown, in one embodiment, the top surface of the separator 212 between two adjacent filler elements 220 is inclined from high to low toward the filler elements 220 on either side. Specifically, along the distribution direction of the filler elements 220, the top surface of the separator 212 is highest in the middle and gradually decreases from the middle to the sides, thereby forming a surface that is inclined from high to low toward the filler elements 220 on both sides. This arrangement allows the reaction solution that lands on the top surface of the separator 212 to flow along the inclined surface of the filler elements 220 on both sides, thereby preventing excessive reaction solution from accumulating on the top surface of the separator 212 and improving the reaction solution utilization rate to a certain extent.

[0064] like Figure 9 As shown, the lowest points on both sides of the top surface of the partition 212 between two adjacent filler pieces 220 are flush with the top surface of the filler piece 220, so that the reaction solution flowing from the top surface of the partition 212 to the filler piece 220 can flow into the top of the filler piece 220, avoiding the phenomenon of reaction solution accumulation when the filler piece 220 is blocked due to the groove structure formed by the two filler pieces 220 and the top surface of the partition 212.

[0065] Reference Figure 1 and Figure 3 As shown, the flue gas treatment device 10 also includes a cooling device 400, which is arranged on the side wall of the reaction device 100. The cooling device 400 forms a longitudinal cooling air path 401 to cool the reaction space 101 through the air flow flowing through the cooling air path 401 to improve the gas-liquid reaction efficiency.

[0066] Reference Figure 1 and Figure 3 As shown, specifically, the cooling device 400 is attached to the side wall of the reaction device 100. An air outlet communicating with the cooling air path 401 is provided at the top of the cooling device 400, and an air inlet communicating with the cooling air path 401 is provided at the bottom. A fan (not shown) is provided inside the cold zone air path. When the fan is activated, air is driven into the cooling air path 401 through the air inlet and out of the cooling air path 401 through the air outlet, forming a continuous cooling air flow within the cooling air path 401. The reaction space 101 is cooled by heat conduction with the side wall of the reaction device 100, thereby improving the reaction efficiency of the flue gas and the reaction solution within the reaction space 101.

[0067] like Figures 10 to 13As shown, the flue gas treatment device 10 also includes at least one diverter device 500, which is arranged in the reaction space 101 and is used to separate the reaction space 101 into multiple flue gas treatment areas distributed in the longitudinal direction. A gas-liquid mixing device 200 is provided in at least one flue gas treatment area. The diverter device 500 includes a plurality of liquid receiving troughs 510 for receiving liquid from above. The plurality of liquid receiving troughs 510 are arranged at intervals so that a flow passage 501 is formed between the side walls of two adjacent liquid receiving troughs 510. And a shielding structure 520 is provided above the flow passage 501. The shielding structure 520 is used to prevent liquid from above the diverter device 500 from entering the flow passage 501. There is a gap between the shielding structure 520 and the side wall of at least one of the two adjacent liquid receiving troughs 510, so that the gas below the diverter device 500 can flow to the top of the diverter device 500 through the flow passage 501.

[0068] Reference Figures 10 to 13 Specifically, multiple liquid receiving grooves 510 are arranged side by side in the same extending direction, with gaps between the sidewalls of adjacent liquid receiving grooves 510. These gaps serve as flow passages 501. A shielding structure 520 is provided above each flow passage 501, i.e., one shielding structure 520 corresponds to each flow passage 501. The shielding structure 520 covers the flow passage 501 in the vertical direction and has gaps between it and the sidewalls of the liquid receiving grooves 510 on both sides.

[0069] Reference Figures 10 to 13 As shown, the splitter device 500 has a flue gas treatment zone above and below it. The splitter device 500 allows airflow from the gas treatment zone below it to flow into the gas treatment zone above it, but prevents liquid from the gas treatment zone above it from flowing into the gas treatment zone below it. In this way, after gas enters the reaction space 101 from the bottom of the reactor 100, it flows from bottom to top, passing through each gas treatment zone in turn, undergoing independent gas-liquid reactions in each gas treatment zone, and finally being discharged from the top of the reactor 100, thereby completing multiple gas treatment processes within the reactor 100.

[0070] Reference Figure 13 The dotted arrows in the middle illustrate the gas flow path. Specifically, the gas below the diverter 500 can flow to the top of the diverter 500 through the gas passage 501 and the gap between the shielding structure 520 and the side wall of the liquid receiving tank 510. Figure 13The solid arrows in the middle illustrate the liquid flow path. The reaction solution sprayed from the top of the diverter 500 can fall directly into the liquid receiving tank 510, or it can fall onto the shielding structure 520 and then flow along the shielding structure into the liquid receiving tank 510. When the gas flows above the diverter 500, it can react with the reaction solution sprayed from above the diverter 500. The liquid sprayed from above the diverter 500 will not fall into the area below the diverter 500, allowing the areas above and below the diverter 500 to undergo different gas treatment processes.

[0071] Reference Figure 10 As shown, for example, the reaction device 100 can be separated into three gas processing areas by two diverter devices 500, which are, from bottom to top, a desulfurization area, a carbon capture area, and a purification area. Specifically, the flue gas undergoes flue gas desulfurization treatment in the desulfurization area, and then enters the carbon capture area through the diverter device 500 between the desulfurization area and the carbon capture area. A decarbonization solution is sprayed in the carbon capture area to decarbonize the flue gas. The sprayed decarbonization solution falls on the diverter device 500 between the desulfurization area and the carbon capture area, and does not fall into the desulfurization area and affect the desulfurization treatment. The flue gas that has undergone decarbonization continues to flow upward, passes through the diverter device 500 between the carbon capture area and the purification area, and enters the purification area. The purification area can absorb the dispersion medium in the flue gas by electrostatic dust removal. The droplets formed by adsorption fall on the diverter device 500 between the carbon capture area and the purification area, and do not fall into the carbon capture area and affect the decarbonization treatment.

[0072] Reference Figure 10 As shown, the two flue gas treatment areas below are provided with the gas-liquid mixing device 200 described in any of the aforementioned embodiments, thereby improving the reaction efficiency of the desulfurization reaction solution and the decarbonization reaction solution with the flue gas.

[0073] It should be noted that one, two, three, four, or more flow diversion devices may be installed within the reactor. Furthermore, if there are sufficient gas processing zones, multiple adjacent gas processing zones may be used to perform the same gas processing process. For example, three flow diversion devices may be installed within the reactor to divide the reaction space into four gas processing zones, which, from bottom to top, are a desulfurization zone, two carbon capture zones, and a purification zone.

[0074] In the solution of this embodiment, a diverter device 500 is provided within the reaction apparatus 100. The diverter device 500 includes a plurality of liquid receiving troughs 510. A flow passage 501 is formed between the sidewalls of two adjacent liquid receiving troughs 510. A shielding structure 520 is provided above the flow passage 501, and the shielding structure 520 can cover the flow passage 501. In this way, liquid sprayed in the area above the diverter device 500 will directly fall into the liquid receiving troughs 510 or onto the shielding structure 520 and then flow into the liquid receiving troughs 510, rather than falling into the area below the diverter device 500. However, gas in the area below the diverter device 500 can flow to the area above the diverter device 500 through the flow passage 501 and the gaps between the shielding structure 520 and the sidewalls of the liquid receiving troughs 510. In other words, different gas-liquid reactions can occur in the area above and below the diverter device 500, which means that different gas-liquid processing processes can be performed within the reaction apparatus 100. Therefore, multiple gas treatment areas can be constructed in one reaction space of a reaction device to realize multiple gas treatment processes, effectively reducing the number of equipment in the flue gas treatment system, thereby reducing the floor space and cost of the flue gas treatment system.

[0075] In addition, because multiple flue gas treatment processes are concentrated in a single reaction device, in order to ensure reaction efficiency while avoiding an excessive increase in the overall height of the reaction device, which would increase the construction cost of the reaction device, the lateral width of the reaction device needs to be increased. In this case, using a large integral packing member would be more inconvenient. Therefore, by adopting the aforementioned gas-liquid mixing device 200 of the present application, multiple horizontally arranged packing members are used to carry out the gas-liquid reaction, effectively reducing the volume of a single packing member, making the installation, replacement, and cleaning of the packing member more convenient, and effectively improving the convenience of the packing member. Moreover, compared with the use of a large-volume packing member, there is a situation where a packing member is partially damaged or needs to be cleaned and the entire packing member needs to be replaced or removed for cleaning. In the case of multiple horizontally arranged packing members, each packing member can be replaced or cleaned individually according to its usage, effectively saving work time and material costs. In addition, the multiple packing members can be supported in the longitudinal direction by the support member and fixed in the transverse direction by the partition member, making the overall structure of the gas-liquid mixing device 200 more stable in the larger transverse dimension, improving the firmness of the installation of the gas-liquid mixing device 200.

[0076] like Figures 11 to 13 As shown, the shielding structure 520 is a smoothly curved surface, that is, both the convex and concave surfaces of the shielding structure 520 are smoothly curved. The concave surface of the shielding structure 520 faces the flow passage 501, and the highest point of the shielding structure 520 is aligned with the flow passage 501 in the vertical direction. Specifically, the highest point of the shielding structure 520 is aligned with the flow passage 501 in the vertical direction. In other words, the convex surface of the shielding structure 520 is inclined from high to low toward the liquid receiving grooves 510 on both sides.

[0077] Those skilled in the art will appreciate that by configuring the shielding structure 520 as a smooth curved surface, with the concave surface of the shielding structure 520 facing the flow passage 501, and with the highest point of the shielding structure 520 aligned vertically with the flow passage 501, the gas from the flow passage 501 can flow to both sides under the guidance of the concave surface of the shielding structure 520, thereby improving the uniformity of gas distribution and contributing to improving the efficiency of the gas-liquid reaction. Furthermore, liquid that falls on the convex surface of the shielding structure 520 can flow to the liquid receiving grooves 510 on both sides under the guidance of the convex surface of the shielding structure 520, thereby preventing liquid from accumulating in the shielding structure 520 and making it less likely for liquid droplets to splash into the flow passage 501.

[0078] It should be noted that in some other embodiments, the shielding structure may also be a curved structure with an angle, such as an acute angle, a right angle, or an obtuse angle, with the highest point, i.e., the angle, aligned with the air flow channel. Furthermore, in some other embodiments, the shielding structure may also be a flat plate-like structure.

[0079] In addition, it should be noted that, in some other embodiments, the shielding structure may also be a complete plate-shaped structure, covering all the flow passages at the same time, and having through holes arranged at positions aligned with the liquid receiving tank in the upper and lower directions.

[0080] It should be noted that, in some embodiments, the diversion device may further include a liquid collecting container, and all liquid receiving troughs are fixedly connected to the liquid collecting container and communicate with the liquid collecting container, so that the liquid falling into the liquid receiving troughs flows into the liquid collecting container and is collected.

[0081] It should be noted that the flow dividing device may not be provided with a liquid collecting container, and multiple liquid collecting tanks may be directly fixed on the plate-like structure and then fixed on the side wall of the reaction device, or may be directly fixed on the side wall of the reaction device. At the same time, the liquid in the liquid collecting tank is extracted using a pump tube device.

[0082] like Figures 14 to 16 As shown, in one embodiment, when a shielding structure 520 is provided for each flow passage 501, the shielding structure 520 is fixedly connected to the sidewall of one of the two adjacent liquid receiving grooves 510, and a gap is formed between the shielding structure 520 and the sidewall of the other. Specifically, for two adjacent sidewalls of the two adjacent liquid receiving grooves 510, the top of the sidewall of one liquid receiving groove 510 extends toward the sidewall of the other liquid receiving groove 510, forming the shielding structure 520 covering the flow passage 501.

[0083] Reference Figure 16The dotted arrows in the middle illustrate the gas flow path. Specifically, the gas below the diverter 500 can flow to the shielding structure 520 through the flow passage 501. Because the shielding structure 520 is fixedly connected to the side wall of one liquid receiving tank 510, the gas can only flow in the direction of the side wall of the other liquid receiving tank 510 with a gap from the shielding structure 520, and finally flow to the top of the diverter 500. Figure 16 The solid arrows in the middle illustrate the liquid flow path. The reaction solution sprayed from above the diverter 500 can fall directly into the liquid receiving tank 510, or it can fall onto the shielding structure 520 and then flow along the shielding structure into the liquid receiving tank 510. When the gas flows above the diverter 500, it can react with the liquid sprayed above the diverter 500. The liquid sprayed above the diverter 500 will not fall into the area below the diverter 500, allowing the areas above and below the diverter 500 to undergo different gas treatment processes.

[0084] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention can be directly determined or deduced from the contents disclosed herein without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
