Description

Technical Field

[0001] This utility model relates to the field of gas processing technology, and in particular to a gas reaction device and a plate structure for use therein. Background Technology

[0002] Gas-liquid reaction technology is widely used in the chemical industry for gas treatment. Simply put, it involves using the chemical or physical reactions that occur during the contact between a gas and a liquid to treat the gas or liquid. For example, the reaction between a gas and a liquid can be used to absorb certain components (such as carbon dioxide or sulfur dioxide) in flue gas, thereby purifying the flue gas. Alternatively, the reaction between a gas and a liquid can be used to release carbon dioxide from a liquid that has absorbed carbon dioxide, thereby obtaining a high concentration of carbon dioxide gas for further treatment. These are all specific applications of gas-liquid reaction technology.

[0003] In practical applications, a reaction space is usually constructed, allowing the gas to be reacted to enter from one part of the reaction space and exit from another. As the gas flows 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 that gas-liquid reaction technology needs to continuously improve. Utility Model Content

[0004] One objective of this invention is to provide a gas reaction device and a plate structure thereof that enable more complete gas-liquid reactions.

[0005] Specifically, this utility model provides a plate structure for a gas reaction device, comprising: The main body panel has multiple air vents and multiple drainage holes; and Multiple drainage structures are disposed on the bottom side of the main body plate. Each drainage structure forms an elongated drainage channel with a top opening and a bottom opening. The top opening of each drainage channel is in contact with the bottom side of the main body plate. Each of the drainage channels corresponds to at least one of the drainage holes, such that liquid on the top side of the main plate can flow into the drainage channel through the drainage hole and the top opening of the drainage channel, and flow out through the bottom opening of the drainage channel.

[0006] Optionally, each of the drainage structures includes a first sidewall and a second sidewall extending along the length of the drainage channel and disposed opposite to each other, wherein the bottom side of the first sidewall is lower than the bottom side of the second sidewall, and the bottom side of the first sidewall is serrated.

[0007] Optionally, the width of each of the drainage channels gradually decreases from the top opening toward the bottom opening.

[0008] Optionally, the width of the bottom opening of each of the drainage channels is set to 1 mm to 10 mm.

[0009] Optionally, the plurality of drainage holes are arranged in rows and columns on the main body plate, with each drainage structure corresponding to a row of drainage holes, and the width of each drainage hole is set to 3 mm to 10 mm.

[0010] Optionally, the distance between two adjacent rows of drainage holes is set to 50 mm to 500 mm.

[0011] Optionally, the top side of the main body plate is provided with a plurality of brim structures, each brim structure corresponding to a ventilation hole, and the projection of each brim structure on the top side of the main body plate at least partially covers its corresponding ventilation hole. The brim structure forms an outlet, and the axis of the outlet intersects the axis of the ventilation hole.

[0012] Optionally, the side of the brim structure facing the vent is configured as a smooth curved surface, with the concave side of the smooth curved surface facing the vent.

[0013] In another aspect of this utility model, a gas reaction apparatus is also provided, comprising: A reaction tower having a reaction space and an inlet and an outlet communicating with the reaction space; A spraying device, disposed in the reaction space, is used to spray the reaction solution that reacts with the gas into the reaction space; and According to any one of the above-described plate structures, the plate structure is disposed within the reaction space and located below the spraying device.

[0014] Optionally, the air inlet is disposed on the side wall of the reaction tower such that the axis of the air inlet extends laterally; The plurality of drainage holes are arranged in rows and columns on the main body plate, with each drainage structure corresponding to a row of drainage holes, and the distribution direction of the plurality of drainage structures is the same as the axial extension direction of the air inlet.

[0015] This utility model discloses a plate structure for a gas reaction device. It features multiple air passages and drainage holes on the main plate, and multiple drainage structures on the bottom side of the main plate. Each drainage structure forms an elongated drainage channel, with at least one drainage hole corresponding to each channel. During use, the reaction solution sprayed by the spray device falls onto the top side of the main plate, ensuring the solution covers the entire surface and provides a contact area for the gas and reaction solution, promoting a more complete reaction. Furthermore, the reaction solution on the top side of the main plate flows through the drainage holes to the bottom of the main plate, then into the corresponding drainage channel, and finally out through the bottom opening of the channel. This creates a water curtain of a certain width from each drainage channel. As the gas flows from the bottom of the main plate, it passes through this water curtain formed by the multiple drainage structures, further increasing the contact area between the gas and reaction solution and ensuring a more complete reaction within the reaction space.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] like Figures 1 to 3 As shown, in one embodiment, the gas reaction apparatus 10 includes a reaction tower 100, a spray device 200, and a plate structure 300. The reaction tower 100 forms a reaction space 101 and an inlet 102 and an outlet 103 communicating with the reaction space 101. The spray device 200 is disposed within the reaction space 101 and is used to spray the reaction solution that reacts with the gas into the reaction space 101. The plate structure 300 is disposed within the reaction space 101 and located below the spray device 200.

[0022] like Figure 1 As shown, the air inlet 102 is located at the bottom of the side wall of the reaction tower 100. The air outlet 103 is located at the top of the reaction tower 100. The spray device 200 is a spray head or a spray pipe with spray holes, etc., used to spray the reaction solution that reacts with the gas into the reaction space 101. The gas to be treated is transported into the reaction space 101 through the air inlet 102 and flows upward inside the reaction space 101. At the same time, the spray device 200 sprays the reaction solution that reacts with the gas into the reaction space 101. Therefore, as the gas flows upward in the reaction space 101, it reacts with the reaction solution in the reaction space 101 to complete the treatment process. The treated gas finally flows out of the reaction space 101 from the air outlet 103.

[0023] like Figures 1 to 4As shown, the plate structure 300 includes a main plate 310 and multiple drainage structures 320. The main plate 310 is provided with multiple air passages 301 and multiple drain holes 302. The multiple drainage structures 320 are disposed on the bottom side of the main plate 310, and each drainage structure 320 forms an elongated drainage channel 303. The drainage channel 303 has a top opening and a bottom opening, and the top opening of each drainage channel 303 is in contact with the bottom side of the main plate 310. The multiple drain holes 302 are respectively disposed corresponding to the drainage channels 303 of the multiple drainage structures 320, so that liquid on the top side of the main plate 310 can flow into the drainage channel 303 through the drain holes 302 and the top opening of the drainage channel 303, and flow out through the bottom opening of the drainage channel 303. Here, the elongated shape of the drainage channel 303 means that the length of the drainage channel 303 is greater than its width and height.

[0024] Reference Figures 1 to 4 As shown, specifically, the main body plate 310 is a square plate. It should be noted that the square plate is only one example of the main body plate 310; the shape of the main body plate 310 can be flexibly set according to the shape of the installed reaction space 101. The main body plate 310 is provided with multiple vent holes 301, allowing gas at the bottom of the plate structure 300 to flow through the vent holes 301 to the top of the plate structure 300. Simultaneously, the reaction solution sprayed by the spray device 200 can fall onto the top side of the main body plate 310, thus covering the top side of the main body plate 310, thereby providing a reaction contact surface for the gas and reaction solution, which helps to make the gas and reaction solution react more fully.

[0025] Continue to refer to Figures 1 to 4 As shown, the main body plate 310 is provided with multiple drainage holes 302, each corresponding to a drainage channel 303 of a plurality of drainage structures 320. That is, each drainage channel 303 corresponds to at least one drainage hole 302, and the spatial extent of the drainage channel 303, projected onto the bottom side of the main body plate 310, covers all corresponding drainage holes 302. Therefore, the reaction solution on the top side of the main body plate 310 can flow through the drainage holes 302 to the bottom of the main body plate 310, then into the corresponding drainage channel 303, and finally out from the bottom opening of the drainage channel 303. In this way, the reaction solution flowing out of each drainage channel 303 can form a water curtain of a certain width. During the flow of gas at the bottom of the main body plate 310, it passes through the water curtain formed by the multiple drainage structures 320, thereby increasing the contact area between the gas and the reaction solution, allowing the gas and the reaction solution to react more fully within the reaction space 101.

[0026] In this embodiment, multiple air vents 301 and multiple drainage holes 302 are provided on the main body plate 310, and multiple drainage structures 320 are provided on the bottom side of the main body plate 310. Each drainage structure 320 forms an elongated drainage trough 303, with each trough corresponding to at least one drainage hole 302. During use of the plate structure 300, the reaction solution sprayed by the spraying device 200 can fall onto the top side of the main body plate 310, thereby covering the top side of the main body plate 310 with the reaction solution, providing a reaction contact surface for the gas and the reaction solution, and helping to make the gas and the reaction solution react more fully. Furthermore, the reaction solution on the top side of the main body plate 310 can flow through the drainage holes 302 to the bottom of the main body plate 310, then into the corresponding drainage trough 303, and then out from the bottom opening of the drainage trough 303. In this way, the reaction solution flowing out of each drainage trough 303 can form a water curtain with a certain width. As the gas flows through the bottom of the main plate 310, it passes through the water curtain formed by multiple drainage structures 320, thereby increasing the contact area between the gas and the reaction solution, allowing the gas and the reaction solution to react more fully in the reaction space 101.

[0027] Reference Figure 2 The orifice area of ​​the drain hole 302 is larger than that of the vent hole 301, so that the reaction solution can flow out of the drain hole 302 more easily. In addition, the drain hole 302 is racetrack-shaped, that is, a shape formed by two opposite straight sides and two opposite curved sides, facilitating liquid outflow. The width of the drain hole 302 is set to 3 mm to 10 mm, for example, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm, etc.

[0028] Reference Figures 1 to 4 As shown, specifically, multiple drainage holes 302 are arranged in rows and columns on the main body plate 310, with each drainage structure 320 corresponding to a row of drainage holes 302. In this embodiment, the multiple drainage holes 302 are divided into seven rows. Correspondingly, seven drainage structures 320 are provided at the bottom of the main body plate 310, with each drainage structure 320 corresponding to a row of drainage holes 302. Furthermore, the distribution direction of the multiple drainage holes 302 in a row is the same as the length direction of the corresponding drainage groove 303. By arranging the multiple drainage holes 302 in rows and columns on the main body plate 310, with each drainage structure 320 corresponding to a row of drainage holes 302, the structure of the plate structure 300 is more regular and easier to manufacture.

[0029] Furthermore, the distance between two adjacent rows of drainage holes 302 is set to 50 mm to 500 mm. Specifically, the center-to-center distance between two adjacent drainage holes 302 in the same column is set to 50 mm to 500 mm. For example, it can be 50 mm, 60 mm, 70 mm, 80 mm, 90 mm, 100 mm, 200 mm, 300 mm, 400 mm, or 500 mm, etc. This setting helps to prevent the reaction solution on the top side of the main plate 310 from flowing away from the drainage holes 302 too quickly, and also ensures that there is a suitable distance between the multiple drainage structures 320, that is, that the water curtain formed by the multiple drainage structures 320 has a suitable distance, thereby allowing the water curtain and gas to have a better contact reaction effect.

[0030] Reference Figures 1 to 3 As shown, furthermore, because the air inlet 102 is located on the side wall of the reaction tower 100, the axis of the air inlet 102 extends laterally. The distribution direction of the multiple drainage structures 320 is the same as the axial extension direction of the air inlet 102. (Reference) Figure 1 As shown, the axis of the air inlet 102 extends in the left-right direction, and multiple drainage structures 320 are distributed in the left-right direction.

[0031] Because the axis of the air inlet 102 extends laterally, the gas entering the reaction space 101 from the air inlet 102 has a certain flow tendency in the direction of the axis extension of the air inlet 102. By making the distribution direction of the multiple drainage structures 320 the same as the direction of the axis extension of the air inlet 102, that is, making the distribution direction of the water curtain formed by the multiple drainage structures 320 the same as the direction of the axis extension of the air inlet 102, it helps the gas to pass through the multiple water curtains more fully, thereby further improving the reaction effect between the gas and the reaction solution.

[0032] like Figures 1 to 4 As shown, each drainage structure 320 includes a first sidewall 321 and a second sidewall 322 extending along the length of the drainage channel 303 and disposed opposite to each other. The bottom edge of the first sidewall 321 is lower than the bottom edge of the second sidewall 322, and the bottom edge of the first sidewall 321 is serrated. Specifically, the elongated drainage channel 303 has a length, a width, and a height. The height is the dimension of the drainage channel 303 in the longitudinal direction, or in the direction of the distribution of the top opening and the bottom opening. The length and width are the two dimensions of the drainage channel 303 in the transverse direction, with the length being the longer dimension. In other words, the bottom edge of the first sidewall 321 is provided with multiple serrations distributed along the length direction.

[0033] By setting the bottom edge of the first sidewall 321 of the drainage structure 320 to a serrated shape, multiple serrations can be used to guide the reaction solution in the drainage tank 303, which helps to make the water curtain formed by the drainage structure 320 more uniform and improves the overall reaction effect with the gas.

[0034] like Figures 1 to 4 As shown, the width of each drainage trough 303 gradually decreases from the top opening to the bottom opening. Specifically, the first sidewall 321 and the second sidewall 322 of the drainage structure 320 gradually approach each other along the direction from the top opening to the bottom opening, thereby forming a drainage trough 303 with a funnel-shaped cross-section. By making the width of the drainage trough 303 gradually decrease from the top opening to the bottom opening, it is convenient for liquid to flow into the drainage trough 303 from the top while preventing the liquid in the drainage trough 303 from flowing out too quickly, which helps to ensure the continuity of the water curtain.

[0035] Furthermore, the width of the bottom opening of each drainage trough 303 is set to 1 mm to 10 mm. For example, it can be 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, 8.5 mm, 9 mm, 9.5 mm, or 10 mm, etc. By setting the width of the bottom opening of each drainage trough 303 to 1 mm, the speed at which liquid flows out from the bottom opening of the drainage trough 303 is more suitable. This helps to prevent liquid from flowing out of the drainage trough 303 too quickly, and also helps to prevent liquid from flowing out of the drainage trough 303 too slowly, thereby helping to ensure the continuity of the formed water curtain.

[0036] refer to Figure 2 In one embodiment, the top side of the main body plate 310 is provided with multiple brim structures (not shown in the figure), each brim structure corresponding to a vent 301. The projection of each brim structure onto the top side of the main body plate 310 at least partially covers its corresponding vent 301. The brim structure has an outlet, the axis of which intersects the axis of the vent 301.

[0037] Specifically, the projection of the brim structure onto the top side of the main body plate 310 completely covers the corresponding vent 301. Furthermore, the axis of the outlet is perpendicular to the axis of the vent 301. Therefore, as gas flows from the bottom side of the main body plate 310 to the top side of the main body plate 310 via the vent 301, the gas passing through the vent 301 is blocked by the brim structure above the vent 301, thus changing its flow direction. The gas whose direction has been changed changes from being perpendicular to the surface of the main body plate 310 to being parallel to the surface of the main body plate 310, making it easier to diffuse along the surface of the main body plate 310. This helps to increase the contact area between the gas and the reaction solution on the surface of the main body plate 310, thereby helping to make the gas and reaction solution react more fully. In addition, the gas whose direction has been changed can collide with each other to form a better gas-liquid mixing effect.

[0038] In addition, the brim structure shields the air vent 301, which helps to reduce the occurrence of the reaction solution sprayed by the spray device passing directly through the air vent 301. This allows more reaction solution to remain on the top side of the main body plate 310 or enter the drainage trough 303 to form a water curtain, so that the reaction solution is used in a place with higher reaction efficiency.

[0039] It should be noted that in some other embodiments, the projection of the brim structure onto the top side of the main body plate may not completely cover the corresponding vent holes, that is, it may only cover a portion of the corresponding vent holes. Additionally, the axis of the outlet may form an acute angle with the axis of the vent hole or face towards the top side of the main body plate, etc.

[0040] The outlet is fitted to the top side of the main body plate 310. Specifically, the outlet formed by the brim structure is a non-closed outlet with a notch, and the notch of the outlet is fitted to the top side of the main body plate 310, thus sealing the notch of the outlet. This helps the airflow from the outlet to fit more closely to the surface of the main body plate 310, thereby helping the gas to diffuse more fully on the surface of the main body plate 310.

[0041] The brim structure has a smooth curved surface on the side facing the vent 301, with the concave side of the smooth curved surface facing the vent 301. The smooth curved surface extends from the surface of the main body plate 310 to the guide outlet. Specifically, the smooth curved surface is a smooth curved surface. Gas from the vent 301 flows towards the smooth curved surface and then flows along the smooth curved surface to the guide outlet. In other words, the smooth curved surface guides the gas to change its flow direction. The smooth curved surface makes the gas flow smoother. It should be noted that the brim structure is prior art.

[0042] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
