DETAILED DESCRIPTION

[0018] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0019] A highly efficient carbon dioxide absorption device for a reaction tower, such as Figure 1 and Figure 2As shown in the figure, it includes an absorption box 1. The absorption box 1 includes a bottom box 11. A top box 12 is installed above the bottom box 11. Ventilation openings 13 are provided on both the top box 12 and the bottom box 11. A fixing plate 2 is connected to the upper part inside the top box 12. A spraying assembly 3 is rotatably connected to the fixing plate 2. The spraying assembly 3 includes a connecting frame and nozzles. A connecting frame is rotatably connected to the fixing plate 2, and 6 nozzles are connected to the connecting frame. A first gear 4 is connected to the spraying assembly 3. A first driving motor 5 is installed in the upper part inside the top box 12. A second gear 6 is connected to the output shaft of the first driving motor 5. The second gear 6 meshes with the first gear 4. A hydraulic cylinder 8 is installed in the lower part inside the bottom box 11. Triangular rib plates for reinforcement are connected to the hydraulic cylinder 8. A lifting plate 7 is connected to the telescopic end of the hydraulic cylinder 8. The lifting plate 7 is slidably connected to the bottom box 11. A boosting mechanism 9 is provided inside the bottom box 11.

[0020] As Figures 1 - 3 shown, the boosting mechanism 9 includes a filler box 91. The filler box 91 is connected inside the bottom box 11. The filler box 91 is of a hollow structure. A mounting plate 92 is connected to the filler box 91. A pressure pipe 93 is connected to the lower part of the mounting plate 92.

[0021] As Figure 1 、 Figure 2 and Figure 4 shown, it further includes a gathering mechanism 10. The gathering mechanism 10 includes a second driving motor 101. The second driving motor 101 is installed below the lifting plate 7. The output shaft of the second driving motor 101 is rotatably connected to the lifting plate 7. A third gear 102 is connected to the output shaft of the second driving motor 101. A gathering frame 103 is rotatably connected to the lifting plate 7. The gathering frame 103 is rotatably connected to the telescopic end of the hydraulic cylinder 8. A third gear 102 is also connected to the gathering frame 103. The two third gears 102 mesh with each other.

[0022] It should be noted that the reaction tower is a device used in the processes of gas purification, separation or recovery. The reaction tower can be used for the absorption of carbon dioxide in the gas. By providing sufficient contact area and time, the carbon dioxide in the gas can fully contact with the absorbent and undergo a chemical reaction, thereby removing carbon dioxide. The gas is injected into the bottom frame 11 through the ventilation port 13 at the lower part, and then the first driving motor 5 is started. The output shaft of the driving motor rotates to drive the second gear 6 to rotate, which drives the first gear 4 to rotate, and then makes the spraying assembly 3 rotate and spray the alkaline solution. The rotating spray makes the alkaline solution contact the gas more evenly and fully. The alkaline solution contacts the carbon dioxide in the gas and undergoes a chemical reaction, forming solid particles such as carbonates, thereby removing carbon dioxide. To accelerate the reaction rate between the alkaline solution and carbon dioxide, it can be achieved by increasing the pressure inside the absorption frame 1. The operator performs a pressurization operation on the absorption frame 1 through the pressure pipe 93. Increasing the pressure helps to increase the solubility of carbon dioxide and thus improve the absorption efficiency. After the carbon dioxide is absorbed, the purified gas can be discharged through the ventilation port 13 at the upper part, thus achieving the effect of gas recovery. Solid particles such as carbonates will precipitate on the lifting plate 7;

[0023] When the solid particles accumulate, the hydraulic cylinder 8 is started. The telescopic end of the hydraulic cylinder 8 drives the lifting plate 7 to move upward. After the lifting plate 7 is lifted upward, the operator can clean the solid particles on the lifting plate 7. To facilitate the operator to clean the solid particles on the lifting plate 7, the gathering mechanism 10 can be used to regularize and gather them. The second driving motor 101 is started. The output shaft of the second driving motor 101 rotates to drive the adjacent third gear 102 to rotate, and then drives another third gear 102 to rotate, making the gathering frame 103 rotate. The gathering frame 103 rotates to gather the solid particles generated by the reaction together, which is convenient for the operator to clean.

[0024] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that these embodiments can be changed without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
