[0029] Applying the technical solution of this embodiment, the top cover structure of the absorption tower includes: a shielding cover body 20, a water storage tank 30 and a guide plate 41. The shielding cover body 20 is covered on the top of the absorption tower 10. The shielding tube 22 can shield the outside of the clean smoke pipe 11, prevent direct sunlight, and reduce the growth of algae. In addition, the guide plate 41 can divert water so that the water can be stored in the water storage tank 30, which can block the algae from obtaining water, reduce the growth rate of algae, effectively reduce the formation of a layer of biofilm, and prevent algae from easily blocking the pipe mouth of the clean smoke pipe 11, thereby reducing the impact on the normal discharge of gas in the absorption tower 10.

The guide plate 41 has a shielding position in which the shielding cover 42 shields the water inlet 31 and a avoiding position in which the shielding cover 42 avoids the water inlet 31. When the guide plate 41 is in the shielding position, the shielding cover 42 can prevent debris from falling directly into the water inlet 31, and when the guide plate 41 is in the avoiding position, the shielding cover 42 can clean the water inlet 31.

In this way, the setting of the avoidance hole 43 prevents the guide plate 41 from interfering with the shielding tube 22 when sliding, and the sealing sleeve always seals the avoidance hole 43, which can prevent debris from falling into the shielding tube 22 below the guide plate 41 through the avoidance hole 43.

[0032] like Figure 1 and Figure 2 As shown, in order to facilitate the deformation of the sealing sleeve, the sealing sleeve includes a corrugated section.

[0034] like Figure 1 and Figure 2 As shown, in order to limit the guide plate 41 to the shielding position, a stop plate 51 is provided on the top wall of the water storage tank 30. When the guide plate 41 is engaged with the stop plate 51, the guide plate 41 is in the shielding position.

[0035] like Figure 1 and Figure 2 As shown, in order to facilitate the water on the guide plate 41 to flow smoothly into the water storage tank 30, a guide groove 44 connected to the water inlet 31 is provided on the guide plate 41.

[0036] like Figure 1 and Figure 2 As shown, in order to prevent the water inlet 31 from being blocked, a filter element 52 is provided at the water inlet 31 .

[0037] The present application also provides an absorption tower, such as Figure 1 As shown, an embodiment of the absorption tower includes a tower body and a top cover structure disposed on the top of the tower body, and the top cover structure is the top cover structure of the absorption tower described above. Since the top cover structure of the absorption tower described above can solve the problem in the related art that algae easily block the pipe opening of the clean smoke pipe, the absorption tower including the top cover structure can solve the same technical problem.

[0038] like Figure 1 As shown, the water storage tank 30 is connected to the liquid inlet pipe 12 of the absorption tower 10 through the drainage pipe 23. The liquid inlet pipe 12 and the smoke purification pipe 11 are both arranged on the tower body, and a control valve 24 is arranged on the drainage pipe 23. The control valve 24 can control the on and off of the drainage pipe 23. The water collected in the water storage tank 30 can be used to replenish the absorption tower 10, saving water resources.

[0039] like Figure 1 and Figure 2 As shown, the present application provides a top cover structure of an absorption tower, and an embodiment of the top cover structure of the absorption tower includes: a shielding cover body 20, a water storage tank 30 and a guide plate 41. The shielding cover body 20 is covered on the top of the absorption tower 10. The shielding cover body 20 includes a cover plate 21 and a shielding tube 22, the shielding tube 22 is sleeved on the outside of the clean smoke pipe 11 of the absorption tower 10, and the cover plate 21 is covered on the top of the absorption tower 10. The water storage tank 30 is arranged on the cover plate 21 and is arranged to avoid the shielding tube 22, and the water inlet 31 is arranged on the top wall of the water storage tank 30. The guide plate 41 is sealed and connected to the shielding tube 22, and the guide plate 41 is obliquely arranged on the top wall of the water storage tank 30, and is connected to the water inlet 31.

[0040] The principle of the above structural design is to shield the outside of the clean smoke pipe 11 by the shielding tube 22 in the shielding cover 20 to prevent direct sunlight, thereby reducing the growth of algae. At the same time, the inclined setting of the guide plate 41 and the connection with the water tank 30 can effectively divert rainwater or other water sources to flow into the water tank 30, thereby blocking the way for algae to obtain water, reducing the growth rate of algae, and avoiding algae from blocking the pipe mouth of the clean smoke pipe 11, ensuring the normal discharge of gas in the absorption tower 10. The application scenario is mainly during the operation of the absorption tower 10, especially in sunny areas, which can effectively reduce the impact of algae growth on the operation of the equipment.

The guide plate 41 has a shielding position in which the shielding cover 42 shields the water inlet 31 and a avoiding position in which the shielding cover 42 avoids the water inlet 31 .

[0042] The principle of the above structural design is to prevent debris from falling directly into the water inlet 31 when the guide plate 41 is in the blocking position through the shielding cover 42, so as to avoid clogging of the water inlet 31. At the same time, when the guide plate 41 slides to the avoidance position, the shielding cover 42 can clean the water inlet 31 to ensure that the water inlet 31 is unobstructed. The implementation effect is manifested in that the water inlet efficiency and water quality of the water storage tank 30 are improved and the maintenance cost is reduced. The application scenario is in the daily operation of the absorption tower 10, especially in rainy or windy areas, which can effectively prevent debris from clogging the water inlet 31 and ensure the smooth entry of water. The use process includes adjusting the position of the guide plate 41 according to the weather conditions to control the shielding cover 42 to block or avoid the water inlet 31, and regularly cleaning the shielding cover 42 to keep it clean and functional.

[0043] like Figure 1 and Figure 2 As shown, the guide plate 41 is provided with an avoidance hole 43 for avoiding the shielding tube 22 , and the avoidance hole 43 is connected to the shielding tube 22 through a sealing sleeve.

[0044] The principle of the above structural design is to set an avoidance hole 43 on the guide plate 41 and connect it to the shielding tube 22 through a sealing sleeve to ensure that the guide plate 41 will not interfere with the shielding tube 22 during the sliding process, while maintaining good sealing to prevent debris from falling under the shielding tube 22 through the avoidance hole 43. The implementation effect is manifested in improving the sliding flexibility of the guide plate 41 and the overall sealing of the system, ensuring the stability and safety of the operation of the absorption tower 10.

The use process includes regularly checking the sealing of the avoidance hole 43 and the sealing sleeve to ensure that the guide plate 41 does not leak when sliding, and adjusting the position of the guide plate 41 as needed to adapt to different operating conditions.

[0045] like Figure 1 and Figure 2 As shown, 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 when the guide plate 41 slides and maintain good sealing. The implementation effect is manifested in improving the deformation ability of the sealing sleeve and the overall sealing of the system, ensuring the stability and safety of the operation of the absorption tower 10. The application scenario is that during the operation of the absorption tower 10, especially in situations where the position of the guide plate 41 needs to be adjusted frequently, it can effectively prevent debris from entering under the shielding tube 22 through the avoidance hole 43 while maintaining good sealing. The use process includes regularly checking the pleated section of the sealing sleeve to ensure that it can deform normally when the guide plate 41 slides and maintains sealing.

[0049] The principle of the above structural design is to set a stop plate 51 on the top wall of the water tank 30. When the guide plate 41 slides to the blocking position, the stop plate 51 can limit the position of the guide plate 41, ensuring that it stably blocks the shielding cover 42 above the water inlet 31 to prevent debris from entering. The implementation effect is manifested in improving the operational stability and safety of the system, ensuring the continuity and efficiency of the operation of the absorption tower 10. The application scenario is that during the operation of the absorption tower 10, especially in rainy or windy areas, it can effectively prevent debris from entering the system and ensure the smooth flow of the water inlet 31. The use process includes regularly checking the wear of the stop plate 51 to ensure that it can effectively limit the position of the guide plate 41, and adjusting the position of the guide plate 41 according to weather conditions to adapt to different operating environments.

[0051] The principle of the above structural design is to set a guide groove 44 on the guide plate 41 so that rainwater or other water sources can flow smoothly into the water tank 30 along the guide groove 44, thereby realizing the effective collection and utilization of water sources. The implementation effect is manifested in improving the water intake efficiency of the water tank 30, reducing the waste of water resources, and ensuring the purity of the water source. The application scenario is that during the operation of the absorption tower 10, especially in areas where water resources are relatively scarce, natural water sources such as rainwater can be effectively collected and utilized to reduce operating costs. The use process includes regularly checking the cleanliness and diversion effect of the guide groove 44 to ensure that it can effectively guide the water source into the water tank 30, and adjusting the position of the guide plate 41 according to weather conditions to adapt to different water source collection needs.

[0052] like Figure 1 and Figure 2 As shown, in order to prevent the water inlet 31 from being blocked, a filter element 52 is provided at the water inlet 31 .

[0053] The principle of the above structural design is that by setting a filter element 52 at the water inlet 31, impurities in the water source can be effectively filtered out to prevent them from entering the water tank 30, thereby ensuring that the water inlet 31 is unobstructed and improving the purity of the water source. The implementation effect is manifested in improving the water intake efficiency and water quality of the water tank 30 and reducing maintenance costs. The application scenario is that during the operation of the absorption tower 10, especially in rainy or windy areas, impurities can be effectively prevented from clogging the water inlet 31 to ensure the smooth entry of the water source. The use process includes regularly checking the cleanliness and filtering effect of the filter element 52 to ensure that it can effectively filter impurities, and replacing or cleaning the filter element 52 as needed to maintain its filtering performance.

The implementation effect is manifested in improving the operation stability and efficiency of the absorption tower 10, reducing the maintenance cost, and realizing the conservation and environmental protection of water resources. The application scenarios are wide, including but not limited to industrial waste gas treatment, carbon capture system of thermal power plant, tail gas purification of chemical plant, etc., especially in the absorption tower 10 that needs long-term stable operation, which can significantly improve the reliability and economy of the equipment. The use process includes regularly checking the sealing and diversion effect of the top cover structure to ensure that it can effectively prevent algae growth and collect water sources, and adjust the position of the guide plate 41 according to the operating conditions to adapt to different operating requirements.

[0055] like Figure 1 As shown, the water storage tank 30 is connected to the liquid inlet pipe 12 of the absorption tower 10 through the drainage pipe 23 . The liquid inlet pipe 12 and the smoke purification pipe 11 are both arranged on the tower body. The drainage pipe 23 is provided with a control valve 24 .

[0056] The principle of the above structural design is to introduce the water collected in the water tank 30 into the liquid inlet pipe 12 of the absorption tower 10 through the drain pipe 23 for water replenishment of the absorption tower 10, and at the same time control the on-off of the drain pipe 23 through the control valve 24, so as to realize the intelligent management and utilization of the water source.

[0057] To sum up, the top cover structure and absorption tower of the absorption tower of the present application effectively solve the problem of algae blocking the pipe opening of the clean smoke pipe 11 through the innovative design of the shielding cover body 20, the water storage tank 30 and the guide plate 41, while improving the collection and utilization efficiency of water sources, reducing operating costs, achieving water resource conservation and environmental protection, and improving the operating stability and efficiency of the absorption tower 10, and has broad application prospects and significant economic benefits.

[0064] Filter element 52: A filter element 52 is provided at the water inlet 31 for filtering the water entering the water storage tank 30 to prevent impurities from flowing in with the water, thereby keeping the water clean and reducing blockage 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 control valve 24 is provided on the drain pipe 23, which can accurately control the water flow, realize the directional discharge and recycling of water, and reduce the waste of water resources.

[0069] The water storage tank 30 and the water inlet 31 are located on the left side of the device. Figure 1 The descriptions in the text are consistent, reflecting the coherence and consistency of the design.

[0070] The following components are located at the top of the device, wherein the guide plate 41 and the shielding cover 42 are designed to control the water flow and shield, and the avoidance hole 43 and the guide groove 44 further optimize the water flow guidance and storage effect, ensuring the efficient performance of the device under different working conditions.

[0071] The function of the stop plate 51 and the filter element 52 is Figure 1 As described above, their presence and layout further demonstrate the detailed consideration of the design of the present invention, which is intended to provide a reliable, efficient and easy-to-maintain roof structure.

[0072] Overall, Figure 1 and Figure 2 Together, an innovative absorption tower top cover structure is described. Through the ingenious design of key components such as the shielding cover, water storage tank and guide plate, the problem of algae growth blocking the clean smoke pipe orifice is effectively solved, the operation efficiency and reliability of the absorption tower are improved, and the maintenance cost is reduced. The technical solution of the present invention creates an environment that is not conducive to the growth of algae by means of controlling water flow, blocking sunlight and filtering impurities, ensuring the normal operation and emission efficiency of the absorption tower, and demonstrating its potential value in the fields of environmental protection and industrial application. In the description of the present invention, it should be understood that the orientation or position relationship indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, vertical, horizontal" and "top, bottom" is usually based on the orientation or position relationship shown in the accompanying drawings, only for the convenience of describing the present invention and simplifying the description. In the absence of contrary instructions, these directional words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0073] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0074] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
