[0023] Specifically, the recovery component 6 includes a connecting pipe 61, a collection box 62, a top cover 63, a connecting rod 64, a filter screen 65, a drainage block 66, a box door 67 and a collection box 68, wherein a connecting pipe 61 is provided on the surface of the outlet pipe 5, a collection box 62 is provided at one end of the connecting pipe 61, a top cover 63 is provided at the upper end of the inner part of the collection box 62, a connecting rod 64 is symmetrically provided at the lower end of the top cover 63, a filter screen 65 is provided at one end of the connecting rod 64, a drainage block 66 is symmetrically provided at the lower end of the filter screen 65, a collection box 68 is provided at the lower end of the collection box 62, and a box door 67 is provided on one side of the collection box 62.

[0024] By adopting the above technical solution, when the absorption liquid is recovered, the absorption liquid enters the collection box 62 through the connecting pipe 61, and is guided to the filter screen 65 by the drainage block 66. After being filtered, the absorption liquid falls into the interior of the collection box 68, and the recovery of the absorption liquid is completed. The staff can rotate the box door 67 upward to remove the collection box 68, and pull the top cover 63 upward to drive the connecting rod 64 and the filter screen 65, so that the filter screen 65 can be taken out, which is convenient for cleaning the filter screen 65.

[0025] Specifically, a sealing ring is provided inside the connecting pipe 61, and the shape of the filter screen 65 is set to be conical.

[0026] By adopting the above technical solution, when the absorption liquid is recovered, the sealing ring can prevent the absorption liquid from leaking from the gap, and the conical filter screen 65 can guide the absorption liquid to the center to prevent the absorption liquid from entering the collection box 68.

[0027] When this embodiment is in use: the absorption liquid enters the collection box 62 through the connecting pipe 61, and is guided to the filter screen 65 by the drainage block 66. After being filtered, the absorption liquid falls into the interior of the collection box 68, and the absorption liquid can be recovered. The staff can rotate the box door 67 upwards to remove the collection box 68, and pull the top cover 63 upwards to drive the connecting rod 64 and the filter screen 65 to remove the filter screen 65, which is convenient for cleaning the filter screen 65. When the absorption liquid is recovered, the sealing ring can prevent the absorption liquid from leaking from the gap, and the conical filter screen 65 can guide the absorption liquid to the center to prevent the absorption liquid from entering the collection box 68. Example 2

[0028] The difference between this embodiment and embodiment 1 is that: specifically, the disassembly and assembly component 7 includes a shell 71, a disassembly and assembly block 72, a fixed block 73, a rotating shaft 74, a baffle 75 and a limiting mechanism 76, wherein a shell 71 is provided at the upper end of the tower shell 1, a disassembly and assembly block 72 is provided inside the shell 71, a fixed block 73 is symmetrically provided at the lower end of the shell 71, a rotating shaft 74 is provided inside the fixed block 73, a baffle 75 is provided on one side of the rotating shaft 74, and a limiting mechanism 76 is provided on one side of the shell 71.

[0029] By adopting the above technical solution, when the defogger plate 4 needs to be replaced, the limiting mechanism 76 is used to release the limit on the baffle 75, and the baffle 75 is rotated around the fixed block 73 so that it no longer blocks the opening on one side of the shell 71. At this time, the staff can pull the disassembly block 72, so that the disassembly block 72 can drive the defogger plate 4 to be taken out.

[0030] Specifically, the limiting mechanism 76 includes a support block 761 , a spring 762 and a stopper 763 , wherein the support block 761 is provided on one side of the shell 71 , the spring 762 is provided inside the support block 761 , and the stopper 763 is provided at the lower end of the spring 762 .

[0031] By adopting the above technical solution, when limiting the baffle 75, the block 763 is pushed upward. When the baffle 75 rotates and blocks the opening on one side of the shell 71, the block 763 is released, and the spring 762 rebounds and pushes the block 763, thereby limiting the baffle 75 and preventing the baffle 75 from being unstable and rotating.

[0032] Specifically, a pull block is provided on one side of the disassembly block 72 , and a rubber pad is provided on one side of the baffle 75 .

[0033] By adopting the above technical solution, when pulling the disassembly block 72, the pulling block facilitates the staff to pull the disassembly block 72, and the rubber pad can make the baffle 75 completely fit into the opening on one side of the shell 71, thereby improving the shielding and sealing effect.

[0034] When the visor 75 is in the closed position, the stopper 763 is pushed upwards, and the spring 762 rebounds and pushes the stopper 763, thereby limiting the position of the visor 75 and preventing the visor 75 from rotating due to instability. When the visor 75 is in the closed position, the visor 75 is pulled out of the closed position to prevent the visor 75 from rotating due to instability. When the visor 75 is in the closed position, the visor 75 is pulled out of the closed position to prevent the visor 75 from rotating due to instability.

[0035] The structure and use principle of the tower shell, air inlet pipe 2, guide plate 3, demister plate 4, water outlet pipe 5 and packing section 8 in the utility model have been disclosed in a rectifying carbon capture absorption tower disclosed in Chinese patent application No. 202321007297.5.

[0036] The working principle and use process of the present invention are as follows: When the rectifier carbon capture absorption tower is in use, the absorption liquid enters the interior of the collection box 62 through the connecting pipe 61, and is guided to the filter screen 65 by the drainage block 66. After being filtered, the absorption liquid falls into the interior of the collection box 68, and the recovery of the absorption liquid is completed. The staff can rotate the box door 67 upward to take out the collection box 68, and pull the top cover 63 upward to drive the connecting rod 64 and the filter screen 65, so that the filter screen 65 can be taken out, which is convenient for cleaning the filter screen 65. When the absorption liquid is recovered, the sealing ring can prevent the absorption liquid from leaking from the gap. The conical filter screen 65 can guide the absorption liquid to the center to prevent the absorption liquid from entering the collection box 68. The limiting mechanism 76 is used to release the limit of the baffle 75, and the baffle 75 is rotated around the fixing block 73 so that it no longer blocks the opening on one side of the shell 71. At this time, the staff can pull the disassembly block 72, so that the disassembly block 72 can drive the defogger plate 4 to be taken out. When limiting the baffle 75, push the block 763 upward. When the baffle 75 rotates and blocks the opening on one side of the shell 71, release the block 763, and the spring 762 rebounds to push the block 763. In this way, the baffle 75 can be limited to prevent the baffle 75 from rotating due to instability.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
