Description

Technical Field

[0001] This utility model relates to the field of packing assembly technology, specifically a high-efficiency extraction tower packing assembly. Background Technology

[0002] An extraction tower, also known as a liquid-liquid mass transfer tower, is a commonly used liquid-liquid mass transfer device in industries such as chemical manufacturing, petroleum refining, and environmental protection. Liquid-liquid extraction is a method of mass transfer that uses another liquid (called a solvent, which is immiscible with the solvent in the mixture solution) to extract one or more compound components from a solution, thereby achieving separation, enrichment, and purification. Extraction towers require packing material during operation.

[0003] Chinese Patent No. 201820208066.3 discloses a hydrogen peroxide extraction tower. The extraction tower includes a composite tray section and a regular tray section from top to bottom. The composite tray section includes several layers of composite trays, and the composite tray includes a sieve plate, a coalescing packing layer, a void zone, a flow guiding packing layer, a mass transfer packing layer, and a downcomer.

[0004] During use, the feeding and unloading of the packing material is very inconvenient, resulting in a long replacement time and affecting the use of the equipment. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency extraction tower packing assembly to solve the problems mentioned in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency extraction tower packing assembly, comprising a packing assembly: the packing assembly is installed inside the middle of the extraction tower body, the packing assembly consists of a packing cylinder and an mounting plate, the packing cylinder is installed on one side of the mounting plate, the extraction tower body and the mounting plate are fixed together by a fixing mechanism, a grid plate is installed at the bottom of the packing cylinder, the packing cylinder is filled with packing, and a grid cover plate is placed inside the mounting cylinder above the packing.

[0007] Preferably, the extraction tower body has mounting grooves on the upper and lower sides corresponding to the installation position of the packing assembly, and the upper and lower sides of the packing assembly are embedded in the mounting grooves.

[0008] Preferably, a rubber pad is provided on the inner side of the mounting plate, and the rubber pad is attached to the inner side of the mounting plate with adhesive.

[0009] Preferably, handles are provided on the upper and lower sides of the outer side of the mounting plate, and the handles are fixedly installed on the outer side of the mounting plate by bolts.

[0010] Preferably, the fixing mechanism consists of a screw and a nut. The screw is welded to the outer perimeter of the extraction tower body corresponding to the installation position of the packing assembly. One end of the screw passes through the mounting plate, and the nut is screwed to the outer side of the screw.

[0011] Preferably, a support plate is provided inside the packing cylinder, and the support plate is welded to the inside of the packing cylinder.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. A stable connection between the two is achieved through a fixing mechanism, ensuring reliable installation of the packing assembly inside the tower. The packing assembly allows for quick replacement of the packing inside the extraction tower body during use.

[0014] 2. The design of the mounting groove provides precise positioning and installation interface for the packing assembly. The embedded installation method can effectively limit the horizontal displacement of the packing assembly and ensure its positional accuracy in the extraction tower. This installation method makes the packing assembly fit tightly with the extraction tower body, reducing the possibility of fluid bypassing the gap between the packing assembly and the tower wall, ensuring that the fluid can only pass through the packing layer for mass transfer, thus improving the extraction efficiency.

[0015] 3. The support plate inside the stuffing box plays a role in strengthening the structure and providing auxiliary support. When the stuffing box is filled with a large amount of packing, the weight of the packing itself and the pressure generated by the fluid flowing in the packing layer will put a certain load on the stuffing box wall. The support plate is welded inside the stuffing box, which can distribute and transfer these loads to the stuffing box wall, enhance the overall structural strength of the stuffing box, and prevent the stuffing box from deforming or cracking due to excessive stress.

[0016] 4. The fixing mechanism uses a screw and nut to securely install the packing assembly. The screw is welded to the outside of the extraction tower body, providing a fixed connection point for the mounting plate. After the screw passes through the corresponding through hole on the mounting plate, the mounting plate is gradually pressed onto the extraction tower body by rotating the nut. The rotation of the nut applies axial pressure, making the mounting plate fit tightly against the extraction tower body, ensuring that the packing assembly will not loosen due to fluid pressure, vibration, or other factors during operation.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 In this embodiment of the present invention, a high-efficiency extraction tower packing assembly includes a packing assembly 1. The packing assembly 1 is installed inside the middle of the extraction tower body 6. The packing assembly 1 consists of a packing cylinder 8 and a mounting plate 5. The packing cylinder 8 is installed on one side of the mounting plate 5. The extraction tower body 6 and the mounting plate 5 are fixed together by a fixing mechanism 2. A grid plate 12 is installed at the bottom of the packing cylinder 8. The packing cylinder 8 is filled with packing. The mounting cylinder should have a grid cover plate 13 placed inside the packing cylinder 8 above the packing.

[0025] The extraction tower body 6 has mounting grooves 7 on the upper and lower sides corresponding to the installation position of the packing assembly 1. The upper and lower sides of the packing assembly 1 are embedded in the mounting grooves 7. The design of the mounting grooves 7 provides the packing assembly 1 with precise positioning and installation interface. The embedded installation method can effectively limit the displacement of the packing assembly 1 in the horizontal direction and ensure its positional accuracy in the extraction tower. This installation method makes the packing assembly 1 fit tightly with the extraction tower body 6, reducing the possibility of fluid bypassing the gap between the packing assembly 1 and the tower wall, ensuring that the fluid can only carry out the mass transfer process through the packing layer, and improving the extraction efficiency.

[0026] A rubber pad 3 is provided on the inner side of the mounting plate 5. The rubber pad 3 is attached to the inner side of the mounting plate 5 with adhesive. The rubber pad 3 has good elasticity and sealing performance. After being attached to the inner side of the mounting plate 5, when the fixing mechanism 2 tightens the mounting plate 5 to the extraction tower body 6, the rubber pad 3 is squeezed and deformed, filling the tiny gaps between the mounting plate 5 and the extraction tower body 6 to form a reliable sealing structure. Handles 4 are provided on the upper and lower sides of the outer side of the mounting plate 5. The handles 4 are fixed to the outer side of the mounting plate 5 with bolts. The handles 4 are mainly provided to facilitate the operator to install and disassemble the packing assembly 1. When installing the packing assembly 1, the operator can hold the handle 4 to accurately embed the packing assembly 1 into the mounting groove 7 of the extraction tower body 6. When disassembling, the same force is applied using the handle 4 to remove the packing assembly 1 from the mounting groove 7.

[0027] The fixing mechanism 2 consists of a screw 9 and a nut 10. The screw 9 is welded to the outer perimeter of the extraction tower body 6 corresponding to the installation position of the packing assembly 1. One end of the screw 9 passes through the mounting plate 5. The nut 10 is screwed to the outside of the screw 9. The fixing mechanism 2 achieves the fastening installation of the packing assembly 1 through the cooperation of the screw 9 and the nut 10. The screw 9 is welded to the outside of the extraction tower body 6, providing a fixed connection point for the mounting plate 5. After the screw 9 passes through the corresponding through hole on the mounting plate 5, the mounting plate 5 is gradually pressed onto the extraction tower body 6 by rotating the nut 10. The rotation of the nut 10 applies axial pressure, making the mounting plate 5 fit tightly with the extraction tower body 6, ensuring that the packing assembly 1 will not loosen due to fluid pressure, vibration or other factors during operation.

[0028] A support plate 11 is installed inside the packing cylinder 8. The support plate 11 is welded inside the packing cylinder 8. The support plate 11 plays the role of strengthening the structure and providing auxiliary support inside the packing cylinder 8. When the packing cylinder 8 is filled with a large amount of packing, the weight of the packing itself and the pressure generated by the fluid flowing in the packing layer will put a certain load on the wall of the packing cylinder 8. The support plate 11, which is welded inside the packing cylinder 8, can distribute and transfer these loads to the wall of the packing cylinder 8, thereby enhancing the overall structural strength of the packing cylinder 8 and preventing the packing cylinder 8 from deforming or cracking due to excessive stress.

[0029] The working principle and usage process of this utility model are as follows: The packing assembly 1 is the core mass transfer component of the extraction tower. Its operation is based on increasing the contact area between the two phases to promote the mass transfer process. The packing in the packing cylinder 8 provides a huge specific surface area, which allows the extractant and the liquid to be treated to fully contact each other when flowing through, realizing the transfer of solute from one phase to another. The grid plate 12 is installed at the bottom of the packing cylinder 8. Its function is to support the packing and prevent the packing from falling off, while ensuring that the liquid and gas can pass through smoothly and be evenly distributed in the packing layer. The grid cover plate 13 is placed on top of the packing to prevent the packing from moving or deforming under the impact of fluid, maintaining the stability and structural integrity of the packing layer, and ensuring the stability of the mass transfer efficiency. The mounting plate 5 serves to connect and fix the packing cylinder 8 and the extraction tower body 6. The two are firmly connected by the fixing mechanism 2 to ensure the reliable installation of the packing assembly 1 in the tower. The setting of the packing assembly 1 allows for quick replacement of the packing inside the extraction tower body 6 during use.

[0030] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
