[0002] The gas-liquid reaction technology is widely applied in the chemical industry. Briefly speaking, it is to utilize the chemical or physical reaction occurring during the contact process between a gas and a liquid to treat the gas or the liquid. For example, certain components in flue gas (such as carbon dioxide or sulfur dioxide) are absorbed by using the reaction between the gas and the liquid, so as to purify the flue gas, or carbon dioxide is precipitated from the liquid absorbing carbon dioxide by using the reaction between the gas and the liquid, so as to obtain high-concentration carbon dioxide gas for subsequent treatment of the carbon dioxide gas. These are all specific applications of the gas-liquid reaction technology.

[0003] In the actual application process, usually a reaction space is constructed to enable the gas to be reacted to enter from one place of the reaction space and flow out from another place. During the flow of the gas in the reaction space, it reacts with the liquid to be reacted. Therefore, how to make the reaction between the gas and the liquid in the reaction space more sufficient is one of the directions that the gas-liquid reaction technology needs to continuously improve. Summary of the Utility Model

[0004] An object of the utility model is to provide a gas-liquid reaction component and a gas-liquid reaction device that can make the gas-liquid reaction more sufficient.

[0005] In particular, the utility model provides a gas-liquid reaction component, including:

[0006] A bottom plate, which is formed with at least one convex structure extending from one side of itself to the opposite side, and the convex structure is formed with a plurality of first through holes; and

[0007] A cover plate, which is covered above the convex structure and has a gap with the convex structure. There is an air passage gap between the side edges of the cover plate on both sides of the convex structure and the bottom plate, and the highest point of the air passage gap is lower than the lowest point of the plurality of first through holes.

[0008] Optionally, the convex structure has a horizontal part and two inclined parts, and the two inclined parts are respectively located on both sides of the horizontal part, and the plurality of first through holes are all formed in the horizontal part.

[0009] Optionally, the gas-liquid reaction assembly includes a plurality of guiding structures disposed on the top surface of the horizontal portion, and each guiding structure corresponds to one of the first through holes. The projection of the guiding structure on the top surface of the horizontal portion at least partially covers the corresponding first through hole. The guiding structure is formed with a guiding outlet, and the axis of the guiding outlet intersects with the axis of the first through hole to guide the airflow passing through the first through hole to the side where one of the inclined portions is located via the guiding structure.

[0010] Optionally, a bent surface is formed on one side of the guiding structure facing the first through hole, and the concave side of the bent surface faces the first through hole to guide the flow direction of the airflow passing through the first through hole via the bent surface.

[0011] Optionally, the bent surface is a smooth curved surface.

[0012] Optionally, the guiding outlets of some of the plurality of guiding structures face one of the inclined portions, and the guiding outlets of the other part face the other inclined portion.

[0013] Optionally, the bottom plate is provided with a plurality of second through holes, and the second through holes are disposed on the part of the bottom plate that avoids the convex structure.

[0014] Optionally, the bottom plate is provided with a plurality of the convex structures, and the extending directions of the plurality of convex structures are the same to form a recessed area between two adjacent convex structures.

[0015] In another aspect of the present invention, a gas-liquid reaction device is further provided, including:

[0016] A reaction device that forms a reaction space; and

[0017] At least one gas-liquid reaction assembly according to any one of the above, and the gas-liquid reaction assembly is disposed in the reaction space in a form that the cover plate is above the bottom plate.

[0018] Optionally, the gas-liquid reaction device includes a plurality of the gas-liquid reaction assemblies, and the plurality of gas-liquid reaction assemblies are longitudinally distributed in the reaction space.

[0019] The gas-liquid reaction component and the gas-liquid reaction device of the present utility model form a convex structure on the bottom plate, form a plurality of first through holes in the convex structure, then cover the convex structure with a cover plate, and form a gas passing gap lower than the first through holes between the cover plate and the bottom plate. When liquid continuously falls on the gas-liquid reaction component, it will submerge the gas passing gap between the cover plate and the bottom plate. On the other hand, after the gas passes through the first through holes from the bottom of the bottom plate and is blocked by the cover plate, it can only flow towards the gas passing gap between the cover plate and the bottom plate. In this way, a gas explosion phenomenon can be generated at the gas passing gap between the cover plate and the bottom plate, so that the gas can completely penetrate into the liquid and react with the liquid, making the reaction between the gas and the liquid more sufficient and helping to improve the reaction efficiency of the gas and the liquid.

[0029] As Figure 1 shown, in one embodiment, the gas-liquid reaction device 10 includes a reaction device 100 and two gas-liquid reaction components 200. The reaction device 100 forms a reaction space 101. The gas-liquid reaction components 200 are disposed in the reaction space 101. And the two gas-liquid reaction components 200 are distributed longitudinally in the reaction space 101. That is to say, one gas-liquid reaction component 200 is located above the other gas-liquid reaction component 200.

[0030] As Figure 1 shown, the gas-liquid reaction device 10 is provided with an air inlet 102 and a spraying device 300. The gas to be reacted enters the reaction space 101 from the air inlet 102. The spraying device 300 is disposed in the reaction space 101 and is located above the gas-liquid reaction components 200, and is used for spraying the liquid that reacts with the gas into the reaction space 101, so that the liquid and the gas react in the reaction space 101.

[0031] Referring to Figure 1 shown, exemplarily, the reaction device 100 can be a desulfurization tower for desulfurizing flue gas, or an absorption tower for decarbonizing flue gas, etc. Taking the reaction device 100 as a desulfurization tower as an example, the flue gas enters the reaction space 101 from the air inlet 102 and flows from the bottom of the reaction space 101 to the top of the reaction space 101. At the same time, the spraying device 300 sprays the liquid for desulfurization into the reaction space 101. The liquid and the flue gas are mixed and reacted in the reaction space 101, and the liquid absorbs sulfur dioxide in the flue gas, thereby desulfurizing the flue gas.

[0032] In addition, the liquid will fall on the gas-liquid reaction component 200, and the gas will also flow through the gas-liquid reaction component 200. The gas-liquid reaction component 200 can improve the reaction adequacy between the gas and the liquid. As described below, the specific structure of the gas-liquid reaction component 200 and how to achieve the effect will be described.

[0033] As shown in FIGS. 2 to Figure 4 As shown, in one embodiment, the gas-liquid reaction component 200 includes a bottom plate 210 and a cover plate 220. The bottom plate 210 is formed with at least one convex structure 211 extending from one side of itself to the opposite side, and the convex structure 211 is formed with a plurality of first through holes 201. The cover plate 220 is disposed above the convex structure 211 and has a gap from the convex structure 211. There is a gas passing gap between the side edges of the cover plate 220 on both sides of the convex structure 211 and the bottom plate 210, and the highest point of the gas passing gap is lower than the lowest point of the plurality of first through holes 201.

[0034] As Figures 2 to 4 shown, specifically, the convex structure 211 has a horizontal portion 2111 and two inclined portions 2112. The two inclined portions 2112 are respectively located on both sides of the horizontal portion 2111, and the plurality of first through holes 201 are all formed in the horizontal portion 2111.

[0035] Referring to Figures 2 to 4 shown, specifically, the bottom plate 210 is a square plate, and the convex structure 211 is a convex portion bent from the square bottom plate 210, extending from one side edge of the square bottom plate 210 to the opposite side edge, and the cross-sectional shape of the convex structure 211 is an isosceles trapezoid. The horizontal portion 2111 is the top edge of the trapezoid, and the two inclined portions 2112 are the two waists of the trapezoid. The horizontal portion 2111 is formed with a plurality of first through holes 201.

[0036] Continuing to refer to Figures 2 to 4 shown, the cross-sectional shape of the cover plate 220 is also an isosceles trapezoid. It is placed on the bottom plate 210 in such a way that the bottom ends of the two waists contact the bottom plate 210, and the two waists are respectively located on both sides of the convex structure 211, so as to cover the convex structure 211. The height of the cover plate 220 is greater than the height of the convex structure 211, and for the width at the same height, the cover plate 220 is larger than the convex structure 211, so that there is a gap between the cover plate 220 and the convex structure 211. Further, the side edge of the cover plate 220 in contact with the bottom plate 210 is serrated, that is, there are a plurality of gaps distributed at intervals between the cover plate 220 and the bottom plate 210, namely the gas passing gaps.

[0037] Referring to Figures 1 to 2As shown, when performing the gas-liquid reaction operation, the gas to be reacted enters the reaction space 101 from the gas inlet 102 and flows from the bottom of the reaction space 101 to the top of the reaction space 101. At the same time, the spraying device 300 sprays the liquid that reacts with the gas into the reaction space 101. The liquid will fall on the gas-liquid reaction assembly 200. Specifically, it will fall on the cover plate 220 and the part of the bottom plate 210 not covered by the cover plate 220.

[0038] As the liquid continuously falls on the gas-liquid reaction assembly 200, since the first through holes 201 are higher than the gas passing gap, before the liquid level on the bottom plate 210 reaches the first through holes 201, it will gradually submerge the gas passing gap between the cover plate 220 and the bottom plate 210. On the other hand, after the gas flows from the bottom of the gas-liquid reaction assembly 200 to the gas-liquid reaction assembly 200, it passes through the raised structure 211 of the bottom plate 210 via the first through holes 201. Because it is blocked by the cover plate 220 above, the gas can only flow to both sides of the raised structure 211 to flow out from the gas passing gap between the cover plate 220 and the bottom plate 210 and continue to flow to the top of the reaction device 100. And because the liquid submerges the gas passing gap between the cover plate 220 and the bottom plate 210, a gas explosion phenomenon will occur at the gas passing gap between the cover plate 220 and the bottom plate 210, so that the gas and the liquid can react fully.

[0039] In the solution of this embodiment, by forming the raised structure 211 on the bottom plate 210, forming a plurality of first through holes 201 in the raised structure 211, then covering the raised structure 211 with the cover plate 220, and making a gas passing gap lower than the first through holes 201 formed between the cover plate 220 and the bottom plate 210. When the liquid continuously falls on the gas-liquid reaction assembly 200, it will submerge the gas passing gap between the cover plate 220 and the bottom plate 210. On the other hand, after the gas passes through the first through holes 201 from the bottom of the bottom plate 210 and is blocked by the cover plate 220, it can only flow to the gas passing gap between the cover plate 220 and the bottom plate 210. In this way, a gas explosion phenomenon can occur at the gas passing gap between the cover plate 220 and the bottom plate 210, so that the gas can completely penetrate into the liquid and react with the liquid, making the reaction between the gas and the liquid more sufficient and helping to improve the reaction efficiency of the gas and the liquid.

[0040] In addition, by making the convex structure 211 have a horizontal portion 2111 and two inclined portions 2112, such that a plurality of first through holes 201 are all formed in the horizontal portion 2111. When the liquid level height of the liquid reaches the horizontal portion 2111, part of the liquid flows away through the first through holes 201, and part of the liquid can diffuse to a certain extent on the horizontal portion 2111. At the same time, the gas passing through the first through holes 201 from the bottom of the bottom plate 210 will also diffuse on the horizontal portion 2111, so that the gas and the liquid come into contact and react on the surface of the horizontal portion 2111. In other words, the horizontal portion 2111 provides a reaction platform. Compared with the convex structure with inclined surfaces from the middle to both sides, the convex structure 210 having the horizontal portion 2111 helps to further improve the sufficiency of the gas-liquid reaction.

[0041] It should be noted that during the use of the gas-liquid reaction assembly, a certain degree of enclosure is required around the gas-liquid reaction assembly to prevent the liquid from flowing away too quickly from all around. Specifically, it can be that the periphery of the gas-liquid reaction assembly is attached to the side wall of the reaction space, and the side wall of the reaction space is used for enclosure, or a baffle can be provided around the gas-liquid reaction assembly, and the baffle is used for enclosure.

[0042] It should be noted that in some other embodiments, the shapes of the cover plate and the convex structure can also be different. For example, the cross-sectional shape of the cover plate is arc-shaped, and the cross-sectional shape of the convex structure is trapezoidal.

[0043] In addition, it should be noted that in some other embodiments, the convex structure can also be of other shapes. For example, the cross-sectional shape of the convex structure can be arc-shaped, triangular, square, etc., as long as the lowest position of the first through hole is higher than the gas passing gap.

[0044] As Figures 2 to 4 shown, the bottom plate 210 forms two convex structures 211, and the extending directions of the two convex structures 211 are the same, so as to form a recessed area between the two convex structures 211, thereby facilitating the collection of liquid by using the recessed area between the convex structures 211.

[0045] It should be noted that in some other embodiments, the bottom plate can also be provided with one, three, four or more convex structures.

[0046] As Figures 2 to 4As shown, the gas-liquid reaction component 200 includes a plurality of guiding structures 230. The guiding structures 230 are disposed on the top surface of the horizontal portion 2111, and each guiding structure 230 corresponds to a first through hole 201. The projection of the guiding structure 230 on the top surface of the horizontal portion 2111 at least partially covers the corresponding first through hole 201. The guiding structure 230 is formed with a guiding outlet 202, and the axis of the guiding outlet 202 intersects with the axis of the first through hole 201, so as to guide the airflow passing through the first through hole 201 to the side where one of the inclined portions 2112 is located via the guiding structure 230.

[0047] Referring to Figures 2 to 4 As shown, the guiding structure 230 is a shell-like structure protruding from the top surface of the horizontal portion 2111 and at least covering a part of the first through hole 201. The part of the guiding structure 230 in contact with the top surface of the horizontal portion 2111 at least partially surrounds the first through hole 201, and the part protruding from the top surface of the horizontal portion 2111 at least partially covers the corresponding first through hole 201 in the projection on the top surface of the horizontal portion 2111 where it is connected.

[0048] Continuing to refer to Figures 2 to 4 As shown, specifically, in this embodiment, the projection of the guiding structure 230 on the top surface of the horizontal portion 2111 completely covers the corresponding first through hole 201. When the gas passes through the first through hole 201 from the bottom of the bottom plate 210, the vertically upward flow path of the gas will be blocked by the guiding structure 230, so that the gas changes its flow direction.

[0049] Referring to Figures 2 to 4 As shown, further, the guiding structure 230 is also formed with a guiding outlet 202, and the axis of the guiding outlet 202 intersects with the axis of the first through hole 201. Specifically, in this embodiment, the axis of the guiding outlet 202 is parallel to the top surface of the horizontal portion 2111, that is, the axis of the guiding outlet 202 is perpendicular to the axis of the first through hole 201. The gas whose flow direction is changed by the guiding structure 230 flows from the guiding outlet 202 to the space between the protruding structure 211 and the cover plate 220, and flows to the side where one of the inclined portions 2112 is located.

[0050] In other words, the guiding structure 230 forms a guiding air path between the guiding outlet 202 and the first through hole 201. The gas passes through the first through hole 201 and then enters the guiding air path, and under the guidance of the guiding air path, the flow direction is changed, changing from the original direction perpendicular to the top surface of the horizontal portion 2111 to the direction pointing to the side where one of the inclined portions 2112 is located for flowing.

[0051] It should be noted that the guiding structure 230 can be integrally formed with the bottom plate 210, or can be separately formed and then fixed on the bottom plate 210.

[0052] It should be noted that in some other embodiments, the outlet can also be oriented towards the surface of the mixing plate, etc., as long as it intersects with the axis of the through hole.

[0053] Those skilled in the art can understand that by providing the guiding structure 230 corresponding to the first through hole 201, the guiding structure 230 can be used to change the flow direction of the gas passing through the first through hole 201, so that the gas flows in a direction pointing to one side where the inclined portion 2112 is located, that is, it helps the gas to flow to the gas passing gap between the cover plate 220 and the bottom plate 210 more quickly, reducing the accumulation of gas between the top of the convex structure 211 and the cover plate 220 due to vertical flow, thereby improving the gas utilization rate.

[0054] As Figures 2 to 4 shown, a bent surface 231 is formed on the side of the guiding structure 230 facing the first through hole 201, and the concave side of the bent surface 231 faces the first through hole 201 to guide the flow direction of the air flow passing through the first through hole 201 via the bent surface 231. Specifically, the bent surface 231 is a smooth curved surface.

[0055] Referring to Figures 2 to 4 shown, specifically, the concave side of the bent surface 231 faces the first through hole 201, that is, the gas from the first through hole 201 will flow to the concave side of the bent surface 231 and be guided by the concave side of the bent surface 231 to change the flow direction.

[0056] Those skilled in the art can understand that by providing the bent surface 231 on the side of the guiding structure 230 facing the first through hole 201, with the concave side of the bent surface 231 facing the first through hole 201, the bent surface 231 can change the flow direction of the gas more gently, making the gas flow more smoothly and avoiding turbulence caused by too sharp a change in the flow direction. Further, setting the bent surface 231 as a smooth curved surface makes the gas flow more smoothly.

[0057] It should be noted that in some other embodiments, the side of the guiding structure facing the through hole can directly be an inclined plane, which can also play a role in changing the direction.

[0058] Referring to Figures 2 to 4 shown, among the multiple guiding structures 230, some of the outlets 202 face one of the inclined portions 2112, and the other part of the outlets 202 face the other inclined portion 2112. Taking Figure 3 the plane shown as an example, that is, some of the guiding structures 230 on the left guide the gas to the inclined portion 2112 on the left, and some of the guiding structures 230 on the right guide the gas to the inclined portion 2112 on the right. The above structure helps the gas to flow evenly to the gas passing gaps on both sides, so that the gas reacts evenly with the liquid on both sides.

[0059] AsFigure 2 As shown, in one embodiment, the bottom plate 210 is provided with a plurality of second through holes 203, and the second through holes 203 are arranged in a part of the bottom plate 210 that avoids the raised structure 211. When liquid falls on the bottom plate 210, the liquid can pass through the bottom plate 210 from the second through holes 203. In addition, the size of the second through holes 203 is configured such that the liquid flow rate through the second through holes 203 is less than the spraying flow rate of the spraying device, that is, the liquid can accumulate on the bottom plate 210, so as to be able to submerge the air passing gap between the cover plate 220 and the bottom plate 210. When the reaction device finishes working, the spraying device no longer sprays liquid, and the remaining liquid on the bottom plate 210 will gradually flow away from the second through holes 203 and flow to the bottom of the reaction device to be collected.

[0060] Therefore, by providing the second through holes 203 in the part of the bottom plate 210 that avoids the raised structure 211, when the reaction device finishes working and the spraying device no longer sprays liquid, the remaining liquid on the bottom plate 210 can flow to the bottom of the reaction device through the second through holes 203 to be collected, which is convenient for liquid recovery and avoids some liquid remaining on the bottom plate 210 after finishing work.

[0061] Referring to Figures 1 to 4 As shown, the gas-liquid reaction device 10 includes two gas-liquid reaction components 200, and the two gas-liquid reaction components 200 are longitudinally distributed in the reaction space 101. The raised structures 211 of the two gas-liquid reaction components 200 correspond to each other in the longitudinal direction.

[0062] It should be noted that in some other embodiments, the gas-liquid reaction device may also be provided with only one gas-liquid reaction component, or three or more gas-liquid reaction components.

[0063] It should be noted that the cover plate and the bottom plate can be fixed together. Or it can be directly placed on the bottom plate.

[0064] So far, those skilled in the art should recognize that although multiple exemplary embodiments of the present invention have been shown and described in detail herein, still, without departing from the spirit and scope of the present invention, many other variations or modifications that conform to the principles of the present invention can be directly determined or derived based on the content disclosed in the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all these other variations or modifications.
