[0039] As shown in Figure 1 and Figure 2 shown, the application provides a top cover structure of an absorption tower, and the embodiment of the top cover structure of the absorption tower comprises: a shielding cover body 20, a water storage tank 30 and a flow guide plate 41. The shielding cover body 20 is arranged on the top of the absorption tower 10.

[0045] As shown in Figure 1 and Figure 2 , in order to facilitate the deformation of the sealing sleeve, the sealing sleeve includes a pleated section. The principle of this design is to add a pleated section to the sealing sleeve, so that the sealing sleeve can adapt to the position change of the guide plate 41 during sliding, maintaining good sealing performance. The implementation effect is to improve the deformation ability of the sealing sleeve and the overall sealing performance of the system, ensuring the stability and safety of the operation of the absorption tower 10. The application scenario is during the operation of the absorption tower 10, especially in situations where the position of the guide plate 41 needs to be frequently adjusted, which can effectively prevent sundries from entering the lower part of the shielding cylinder 22 through the avoiding hole 43 while maintaining good sealing performance.

Through this design, the position of the guide plate 41 can be precisely controlled to ensure the accurate execution of the blocking and avoidance functions.

[0064] Filter screen 52: A filter screen 52 is provided at the water inlet 31 to filter the water entering the water storage tank 30, prevent impurities from flowing in with the water, keep the water quality clean, and reduce clogging and maintenance frequency.

[0065] Drain pipe 23 and control valve 24: The water storage tank 30 is connected to the liquid inlet pipe 12 of the absorption tower through the drain pipe 23. The drain pipe 23 is equipped with a control valve 24, which can precisely control the water flow, realize the directional discharge and recycling of water, and reduce the waste of water resources.

The location and direction of the drain pipe 23 indicate that the design of this invention emphasizes the smoothness and control of water flow.

[0069] The water storage tank 30 and the water inlet 31 are located on the left side of the device, and...Figure 1 The description in the above is consistent, which embodies the consistency and coherence of the design.

[0070] The following components are located at the top of the device, wherein the deflector 41 and the shielding cover 42 are designed to control water flow and shielding, and the avoidance hole 43 and the flow guide groove 44 further optimize the water flow guiding and storage effect, ensuring the high efficiency of the device in different working states.

[0071] The functions of the stop plate 51 and the filter screen 52 have been described in Figure 2 , and their existence and layout further prove the consideration of the design details of the present application, aiming to provide a reliable, efficient and easy-to-maintain top cover structure.
