Description

Technical Field

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

[0002] Gas-liquid reaction technology is widely used in the chemical industry. Simply put, it is to use the chemical or physical reaction that occurs during the contact between gas and liquid to treat gas or liquid. For example, the reaction between gas and liquid is used to absorb certain components in the flue gas (such as carbon dioxide or sulfur dioxide), thereby purifying the flue gas, or the reaction between gas and liquid is used to cause carbon dioxide to precipitate from the liquid that absorbs carbon dioxide, thereby obtaining a high concentration of carbon dioxide gas for subsequent treatment of the carbon dioxide gas. These are all specific applications of gas-liquid reaction technology.

[0003] In practical applications, a reaction space is usually constructed so that the gas to be reacted enters from one place in the reaction space and flows 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 gas and liquid react more fully in the reaction space is one of the directions in which gas-liquid reaction technology needs to be continuously improved. Utility Model Content

[0004] One purpose of the utility model is to provide a gas-liquid mixing device that can make the gas-liquid reaction more complete.

[0005] A further object of the present invention is to further improve the sufficiency of the reaction between gas and liquid.

[0006] In particular, the utility model provides a gas-liquid mixing device, comprising:

[0007] A reaction device, wherein the reaction device is formed with a reaction space, and a gas inlet is formed at the bottom of the reaction space so that the gas to be reacted can enter the reaction space through the gas inlet; and

[0009] Optionally, a bent surface is formed on one side of the guiding structure facing the through hole, the concave side of the bent surface faces the through hole, and the bent surface extends from the surface of the blending plate to the guiding outlet.

[0010] Optionally, the bent surface is a smooth curved surface.

[0011] Optionally, with the surface of the blending plate as a reference plane and the direction perpendicular to the surface of the blending plate as the height, the height of the highest point of the bent surface is greater than the height of the highest point of the guiding outlet.

[0012] Optionally, the projection of the guiding structure on the surface of the blending plate completely covers the corresponding through hole.

[0013] Optionally, the guiding outlet is in contact with the surface of the blending plate.

[0014] Optionally, the axis of the guiding outlet is parallel to the surface of the blending plate, or the guiding outlet faces the surface of the blending plate.

[0015] Optionally, the guiding outlets of multiple guiding structures face the same direction, and multiple guiding structures are arranged in rows on the surface of the blending plate, and the guiding structures in adjacent rows are staggered.

[0016] Optionally, the gas-liquid blending device includes multiple blending members, and the multiple blending members are distributed longitudinally along the reaction space, and the inclination directions of two adjacent blending members are opposite.

[0017] Optionally, the gas-liquid blending device includes an installation ring frame, and a plurality of groups of support ribs are provided on the inner side wall of the installation ring frame. Each group of support ribs is used to place and support one blending member, so that multiple blending members can be commonly installed in the reaction space via the installation ring frame.

[0018] The gas-liquid mixing device of the utility model is provided with a mixing component in the reaction space of the reaction equipment, and the mixing component is arranged obliquely in the reaction space. The gas to be reacted enters the reaction space from the bottom of the reaction space through the air inlet, encounters the mixing component in the process of flowing to the top of the reaction space, and then passes through the through hole on the mixing plate, changes direction under the guidance of the guide structure, and flows out from the guide outlet. On the one hand, the gas whose direction is changed changes from the original direction perpendicular to the surface of the mixing plate to the direction at an acute angle to the surface of the mixing plate, so that it is easier to diffuse along the surface of the mixing plate. On the other hand, the inclined mixing component is more convenient for the liquid to flow and diffuse on the surface of the mixing plate, so that the gas and liquid are fully contacted and reacted on the surface of the mixing plate, increasing the contact area of ​​the gas and liquid, thereby helping the gas and liquid to react more fully in the reaction space. Moreover, the inclined mixing component ensures the liquid diffusion effect while avoiding the reaction The liquid gathers on the mixing component, thereby avoiding the reaction efficiency from decreasing due to the excessive saturation of the liquid on the surface of the mixing plate.

[0019] Furthermore, the gas-liquid mixing device of the utility model arranges a plurality of mixing components in the reaction space, and makes the inclination directions of two adjacent mixing components opposite, that is, the gas directions changed by two adjacent mixing components are opposite. Therefore, from the perspective of the whole composed of the plurality of mixing components, the gas flows in a reciprocatingly bent flow path in the reaction space, thereby extending the flow path of the gas in the reaction space, helping to make the gas and liquid have more reaction time in the reaction space, thereby further improving the fullness of the reaction of the gas and liquid.

[0031] Such as Figures 1 to 3As shown, in one embodiment, the gas-liquid mixing device includes a reaction device 100 and two mixing members 200. The reaction device 100 forms a reaction space 101, and an air inlet 102 is formed at the bottom of the reaction space 101 for the gas to be reacted to enter the reaction space 101 through the air inlet 102. The mixing member 200 includes a mixing plate 210 and a plurality of guiding structures 220. The mixing plate 210 is formed with a plurality of through holes 201. All the guiding structures 220 are disposed on the surface of the same side of the mixing plate 210, and each guiding structure 220 corresponds to one through hole 201. The projection of the guiding structure 220 on the surface of the mixing plate 210 at least partially covers the corresponding through hole 201. The guiding structure 220 is formed with a guiding outlet 202, and the axis of the guiding outlet 202 intersects with the axis of the through hole 201. The mixing member 200 is inclinedly disposed in the reaction space 101 and is located above the air inlet 102, and the guiding structure 220 is located on the side of the mixing plate 210 facing away from the air inlet 102.

[0032] Referring to Figures 1 to 3 As shown, the reaction device 100 is a device for reacting gas and liquid, and the gas and liquid react in the reaction space 101 of the reaction device 100. Exemplarily, the reaction device 100 may be a desulfurization tower for desulfurizing flue gas, or an absorption tower for decarbonizing flue gas, etc. The gas-liquid mixing device further includes a spraying device 300, and the spraying device 300 is disposed in the reaction space 101 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.

[0033] 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, and 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. Although not shown in the figure, an air outlet is provided at a position near the top end of the reaction device 100. The flue gas flows from the bottom of the reaction space 101 to the top of the reaction space 101 and finally flows out of the reaction space 101 from the air outlet.

[0034] Continuing to refer to Figures 1 to 3 As shown, the mixing member 200 includes a mixing plate 210 and a guiding structure 220. The mixing plate 210 is a square flat plate structure, and the mixing plate 210 is formed with a plurality of through holes 201. The mixing member 200 is disposed in the reaction space 101 and is located above the air inlet 102. Therefore, in the process of the gas to be reacted entering the reaction space 101 from the air inlet 102 and flowing from the bottom of the reaction space 101 to the top of the reaction space 101, it will encounter the mixing member 200, and then flow through the through holes 201 on the mixing plate 210 to the side of the mixing plate 210 facing away from the air inlet 102.

[0035] It should be noted that, in some other embodiments, the mixing plate may also be in other shapes such as circular, polygonal, etc. In addition, the mixing plate may be a whole plate or a plate formed by splicing a plurality of plates.

[0036] Reference Figures 1 to 4 As shown, a guide structure 220 is provided corresponding to each through hole 201, and the guide structure 220 is a shell-like structure protruding from the surface of the mixing plate 210 and covering at least part of the through hole 201. The portion of the guide structure 220 that is in contact with the mixing plate 210 at least partially surrounds the through hole 201, and the projection of the portion protruding from the surface of the mixing plate 210 on the surface of the mixing plate 210 to which it is connected at least partially covers the corresponding through hole 201.

[0037] Continue to refer to Figures 1 to 4 As shown, specifically, in this embodiment, the projection of the guide structure 220 on the surface of the mixing plate 210 completely covers the corresponding through hole 201. The guide structure 220 is located on the side of the mixing plate 210 away from the air inlet 102, that is, in the process of the gas passing through the through hole 201 on the mixing plate 210 and flowing to the side of the mixing plate 210 away from the air inlet 102, the gas will be blocked by the guide structure 220, thereby changing the flow direction.

[0038] Furthermore, the guide structure 220 is further formed with a guide outlet 202, the axis of which intersects with the axis of the through hole 201. Specifically, in this embodiment, the axis of the guide outlet 202 is parallel to the surface of the mixing plate 210, that is, the axis of the guide outlet 202 (refer to Figure 4 The horizontal dotted line) and the through hole 201 are the axis (reference Figure 4 The gas whose flow direction is changed by the guide structure 220 flows from the outlet 202 to the side of the mixing plate 210 away from the air inlet 102 .

[0039] In other words, the guide structure 220 forms a section of air guide path between the outlet 202 and the through hole 201. The gas on the side of the mixing plate 210 facing the air inlet 102 passes through the through hole 201 and enters the air guide path. The flow direction is changed under the guidance of the air guide path, and finally flows from the outlet 202 to the side of the mixing plate 210 away from the air inlet 102. The gas whose direction is changed changes from the direction perpendicular to the surface of the mixing plate 210 to the direction at an acute angle to the surface of the mixing plate 210, so that it is easier to diffuse along the surface of the mixing plate 210.

[0040] It should be noted that the guide structure 220 may be integrally formed with the mixing plate 210 , or may be separately formed and then fixed on the mixing plate 210 .

[0041] 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.

[0042] As shown in Figures 1 to 4 , the mixing member 200 is disposed obliquely in the reaction space 101, that is to say, the surface of the mixing plate 210 is inclined. In addition, the two mixing members 200 are distributed at intervals along the longitudinal direction of the reaction space 101, and the inclination directions of the two mixing members 200 are opposite. As shown in Figure 1 , the lower mixing member 200 is inclined from the lower left to the upper right, and the higher mixing member 200 is inclined from the lower right to the upper left, and the lowest point of the higher mixing member 200 is higher than the highest point of the lower mixing member 200.

[0043] It should be noted that in some other embodiments, one, three or more mixing members can also be provided in the reaction space of the gas-liquid mixing device. In the case of providing multiple mixing members, the multiple mixing members are distributed along the longitudinal direction of the reaction space, and the inclination directions of two adjacent mixing members are opposite.

[0044] Moreover, the spraying device 300 is disposed higher than the two mixing members 200. When the spraying device 300 sprays liquid into the reaction space 101, the liquid can fall on the mixing member 200 and diffuse on the surface of the mixing plate 210. At the same time, because the mixing member 200 is disposed obliquely, it is convenient for the liquid to flow and diffuse on the surface of the mixing plate 210, ensuring the diffusion effect while preventing the reacted liquid from accumulating on the mixing member 200.

[0045] It should be noted that in some other embodiments, multiple spraying devices can also be provided, and each spraying device is at least located above one mixing member. That is, the gas-liquid mixing device is provided with at least one spraying device, and each spraying device is at least located above one mixing member.

[0046] As shown in Figures 1 to 4 , during the working process, the gas to be reacted enters the reaction space 101 from the inlet 102. At the same time, the spraying device 300 sprays liquid into the reaction space 101. The falling liquid and the rising gas meet and react. In addition, when the gas rises to the mixing member 200, it enters the through hole 201 of the mixing member 200, and then flows out from the outlet 202 after changing direction under the guidance of the guiding structure 220. The gas after changing direction diffuses on the surface of the mixing plate 210. At the same time, the liquid sprayed by the spraying device 300 also falls on the surface of the mixing plate 210 and diffuses. The liquid and the gas come into contact on the surface of the mixing plate 210, increasing the contact area, and thus the reaction occurs.

[0047] In the solution of this embodiment, by arranging a mixing member 200 in the reaction space 101 of the reaction device 100 and arranging the mixing member 200 obliquely in the reaction space 101. The gas to be reacted enters the reaction space 101 from the bottom of the reaction space 101 through the air inlet 102. During the process of flowing towards the top of the reaction space 101, it will encounter the mixing member 200, then pass through the through holes 201 on the mixing plate 210, and flow out from the outlet 202 after changing the direction under the guidance of the guiding structure 220. On the one hand, the gas whose direction is changed changes from the direction perpendicular to the surface of the mixing plate 210 to the direction forming an acute angle with the surface of the mixing plate 210, so it is easier to diffuse along the surface of the mixing plate 210. On the other hand, the inclined mixing member 200 is more convenient for the liquid to flow and diffuse on the surface of the mixing plate 210, so that the gas and the liquid can fully contact and react on the surface of the mixing plate 210, increasing the contact area between the gas and the liquid, which helps the gas and the liquid to react more fully in the reaction space 101. Moreover, the inclined mixing member 200 avoids the liquid after the reaction from accumulating on the mixing member 200 while ensuring the liquid diffusion effect, thus avoiding the decrease of the reaction efficiency due to the too high liquid saturation degree on the surface of the mixing plate 210.

[0048] In addition, by making the projection of the guiding structure 220 on the surface of the mixing plate 210 completely cover the corresponding through hole 201, all the gas entering the through hole 201 can be blocked by the guiding structure 220, and the ability of the guiding structure 220 to change the gas flow direction reaches the best, ensuring that all the gas flows in the same direction, which helps to make the gas flow more smoothly.

[0049] Furthermore, by making the axis of the outlet 202 parallel to the surface of the mixing plate 210, the flow direction of the gas flowing out from the outlet 202 fits better with the plane of the mixing plate 210, which further helps the gas to diffuse uniformly on the surface of the mixing plate 210.

[0050] In addition, by arranging a plurality of mixing members 200 in the reaction space 101 and making the inclination directions of two adjacent mixing members 200 opposite, that is to say, the gas directions changed by two adjacent mixing members 200 are opposite. Therefore, from the overall of the plurality of mixing members 200, the gas flows in a reciprocating and bending flow path in the reaction space 101, thus extending the flow path of the gas in the reaction space 101, which helps to make the gas and the liquid have more reaction time in the reaction space 101, thereby further improving the sufficiency of the reaction between the gas and the liquid.

[0051] Refer to Figures 1 to 4As shown, the outlet 202 is in contact with the surface of the mixing plate 210, that is, the outlet 202 formed by the guiding structure 220 is in contact with the surface of the mixing plate 210 where it is located. Specifically, the outlet 202 formed by the guiding structure 220 is an unclosed outlet 202 with a notch, and the notched part of the outlet 202 is in contact with the surface of the mixing plate 210, so that the surface of the mixing plate 210 closes the notch of the outlet 202.

[0052] By making the outlet 202 in contact with the surface of the mixing plate 210, the airflow flowing out of the outlet 202 is more in contact with the surface of the mixing plate 210, which helps the gas to diffuse more fully on the surface of the mixing plate 210.

[0053] Refer to Figures 1 to 4 As shown, on the side of the guiding structure 220 facing the through hole 201, there is a bent surface 203 formed. The concave side of the bent surface 203 faces the through hole 201, and the bent surface 203 extends from the surface of the mixing plate 210 to the outlet 202. Specifically, the bent surface 203 is a smooth curved surface.

[0054] Refer to Figure 4 As shown, specifically, the concave side of the bent surface 203 faces the through hole 201, and the bent surface 203 extends from the surface of the mixing plate 210 to the outlet 202. That is, the gas from the through hole 201 will flow to the bent surface 203 and then flow along the bent surface 203 to the outlet 202. That is to say, the bent surface 203 guides the gas to change the flow direction.

[0055] By providing the bent surface 203 on the side of the guiding structure 220 facing the through hole 201, with the concave side of the bent surface 203 facing the through hole 201 and the bent surface 203 extending from the surface of the mixing plate 210 to the outlet 202, the gas from the through hole 201 will flow to the bent surface 203 and then, under the guidance of the bent surface 203, change the flow direction and flow to the outlet 202. Moreover, the bent surface 203 can change the flow direction of the gas more gently, making the gas flow more smoothly and avoiding turbulent flow caused by too sharp a change in the flow direction.

[0056] Furthermore, the bent surface 203 is set as a smooth curved surface to make 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] Such as Figures 1 to 4 As shown, further, taking the surface of the mixing plate 210 as the reference plane and the direction perpendicular to the surface of the mixing plate 210 as the height, the height of the highest point of the bent surface 203 is greater than the height of the highest point of the outlet 202.

[0059] Reference Figure 4 As shown, the height of the highest point of the bent surface 203 relative to the surface of the mixing plate 210 is H, and the height of the highest point of the outlet 202 relative to the surface of the mixing plate 210 is h, and H is greater than h. That is to say, the bent surface 201 can be regarded as having an adjacent first part and a second part. The first part is adjacent to the surface of the mixing plate 210, the second part is adjacent to the first part and is connected to the outlet 202. The first part extends upward and extends in the direction of the outlet 202, and the second part extends downward and extends in the direction of the outlet 202. Therefore, when the bent surface 203 guides the gas to the outlet 202, the gas will be guided in the direction pointing to the surface of the mixing plate 210 in the last section, so as to guide the gas to flow toward the surface of the mixing plate 210.

[0060] By making the height of the highest point of the bent surface 203 greater than the height of the highest point of the outlet 202, the gas flowing out of the outlet 202 will flow toward the surface of the mixing plate 201, which helps the gas to diffuse more fully on the surface of the mixing plate 210.

[0061] As Figures 1 to 3 shown, the outlets 202 of the plurality of guiding structures 220 have the same orientation, and the plurality of guiding structures 220 are distributed in rows on the surface of the mixing plate 210, and the guiding structures 220 in adjacent rows are staggered.

[0062] Reference Figure 3 As shown, specifically, in the plane shown in Figure 3 the plurality of guiding structures 220 vertically aligned are one row. That is, from left to right, there are 15 rows of guiding structures 220 on the mixing plate 210. Taking the first row and the second row from left to right as an example, the guiding structures 220 in the adjacent two rows are staggered. That is to say, in the left-right direction, the guiding structures 220 in the first row are not aligned with the guiding structures 220 in the second row. Specifically, each guiding structure 220 in the second row corresponds to the position between two adjacent guiding structures 220 in the first row.

[0063] Reference Figures 1 to 3 As shown, further, the outlets 202 of all the guiding structures 220 have the same orientation, all facing the higher part of the inclined mixing member 200.

[0064] By making the plurality of guiding structures 220 distributed in rows on the surface of the mixing plate 210 and making the guiding structures 220 in adjacent rows staggered, the gas flowing out of the outlet 202 can be more fully diffused on the surface of the mixing plate 210.

[0065] As Figures 1 to 6As shown, in one embodiment, the gas-liquid mixing device includes a mounting ring frame 400. A plurality of groups of support ribs 410 are provided on the inner sidewall of the mounting ring frame 400. Each group of support ribs 410 is used to place and support a mixing member 200, so that a plurality of mixing members 200 can be commonly mounted in the reaction space 101 via the mounting ring frame 400.

[0066] Specifically, the shape of the region surrounded by the mounting ring frame 400 is substantially the same as the outer shape of the mixing member 200, that is, it is generally a square region, so that the mixing member 200 can be placed in the region surrounded by the mounting ring frame 400. Two groups of support ribs 410 are provided on the inner sidewall of the mounting ring frame 400. Each group of support ribs 410 is used to support a mixing member 200. Specifically, each group of support ribs 410 can be four support ribs formed on the four inner sidewalls of the mounting ring frame 400, or three support ribs formed on the three inner sidewalls of the mounting ring frame 400, or two support ribs formed on the two opposite inner sidewalls of the mounting ring frame 400.

[0067] Therefore, two mixing members 200 can be placed on each mounting ring frame 400. And when the mounting ring frame 400 is placed in the reaction space 101, the two groups of support ribs 410 are inclined, and the inclination directions are opposite. Thus, the two mixing members 200 can be commonly mounted in the reaction space 101 via the mounting ring frame 400, so that the two mixing members 200 are inclined in the reaction space 101 and the inclination directions are opposite.

[0068] In the solution of this embodiment, by providing the mounting ring frame 400 in the reaction space 101, and the mounting ring frame 400 is provided with a plurality of groups of support ribs 410, and each group of support ribs 410 is used to place and support a mixing member 200, so that a plurality of mixing members 200 can be commonly mounted in the reaction space 101 via the mounting ring frame 400. Therefore, it is not necessary to separately mount a plurality of mixing members 200 in the reaction space 101. Instead, after mounting the mounting ring frame 400 outside the reaction space 101 and then mounting the mounting ring frame 400 into the reaction space 101, the installation of a plurality of mixing members 200 can be completed, thereby improving the installation convenience of a plurality of mixing members 200 in the reaction space 101.

[0069] It should be noted that in some other embodiments, the mounting ring frame can also be provided with three or more groups of support ribs.

[0070] At this point, those skilled in the art should recognize that although numerous exemplary embodiments of the present utility model have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present utility model can still be directly determined or derived from the disclosed content of the present utility model without departing from the spirit and scope of the present utility model. Therefore, the scope of the present utility model should be understood and recognized as covering all such other variations or modifications.
