Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a fluoroplastic Pall ring for packed towers. Background Technology

[0002] In many chemical production processes, such as distillation, absorption, and desorption, packed towers are extremely important gas-liquid mass transfer devices. Their working principle is to provide sufficient contact area for the gas and liquid phases through the packing material inside the tower, thereby realizing the transfer and separation of substances. During the actual operation of packed towers, especially under conditions of high gas velocity, high liquid velocity, or the presence of solid particles, fluoroplastic Pall rings are prone to deformation and breakage. Deformed Pall rings will change the flow path and distribution of gas and liquid, leading to a decrease in mass transfer efficiency. Broken Pall ring fragments may block the channels inside the tower, increase pressure drop, and in severe cases, even affect the normal operation of the packed tower, requiring shutdown for maintenance and packing replacement, thereby increasing production costs and production cycle. Therefore, we have introduced a fluoroplastic Pall ring for packed towers. Utility Model Content

[0003] The main objective of this invention is to provide a fluoroplastic Pall ring for packed towers, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A fluoroplastic Pall ring for a packed tower includes a lower ring body, a connecting device fixedly connected to the inner side of the lower ring body, a docking device snapped into the middle of the upper end of the connecting device, an upper ring body fixedly connected to the outer side of the docking device, and a fixed ring movably connected between the upper end of the connecting device and the lower end of the docking device.

[0006] The connecting device includes an inner rib plate, which has a slot at the middle of its upper end and is fixedly connected to the inner side of the lower ring body.

[0007] Preferably, the docking device includes a second inner stiffening plate, and a locking post is fixedly connected to the lower middle part of the second inner stiffening plate. The second inner stiffening plate is fixedly connected to the inner side of the upper ring body.

[0008] By adopting the above technical solution, the No. 2 inner stiffening plate plays a dual role of connection and reinforcement. On the one hand, as a key component of the docking device, it achieves accurate docking of the upper ring body and the lower ring body through the cooperation of the locking post at its lower end with the locking groove of the connecting device, ensuring the integrity of the entire Pall ring structure. On the other hand, the No. 2 inner stiffening plate is fixedly connected to the inner side of the upper ring body, enhancing the structural strength of the upper ring body, enabling it to better withstand the impact and pressure brought by gas-liquid flow, avoiding deformation or damage to the upper ring body during use, and extending the service life of the Pall ring.

[0009] Preferably, the position and size of the card post correspond to the position and size of the card slot, and the card post has a flower-shaped structure.

[0010] By adopting the above technical solution, the corresponding dimensions of the locking pin and the locking slot ensure that the upper and lower ring bodies can be accurately connected, avoiding problems such as structural instability or poor gas-liquid flow caused by inaccurate connection.

[0011] Preferably, the second inner stiffener plate has a cross-shaped structure, just like the first inner stiffener plate, and the structure of the second inner stiffener plate is the same as that of the first inner stiffener plate, with the two plates staggered vertically.

[0012] By adopting the above technical solution, the gas and liquid will continuously change their flow direction between the interlaced internal ribs, increasing the contact opportunities and contact time between the gas and liquid. At the same time, this interlaced structure also allows the gas and liquid to be more evenly distributed inside the Pall ring, avoiding the phenomenon of gas-liquid flow deviation, improving the gas-liquid mass transfer efficiency, and thus improving the separation effect of the packed tower.

[0013] Preferably, the cross-sections of the second inner stiffening plate and the first inner stiffening plate are in a cross-shaped structure.

[0014] By adopting the above technical solution, the cross-section of the star shape further increases the specific surface area of ​​gas-liquid contact. The star shape structure enables the gas and liquid to form multiple branch flows and vortices within the Pall ring, further enhancing the degree of gas-liquid mixing, promoting the rapid transfer of substances between the gas and liquid phases, and improving the overall performance of the packed tower.

[0015] Preferably, the diameter of the upper ring body is the same as the diameter of the lower ring body, and the diameter of both the upper ring body and the lower ring body is larger than the diameter of the fixed ring.

[0016] By adopting the above technical solution, the upper and lower rings have the same diameter, which ensures the structural symmetry of the entire Pall ring. This allows the gas and liquid to be evenly distributed around the ring when flowing through it, avoiding uneven gas and liquid flow caused by differences in ring diameter.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In this utility model, the lower ring provides stable support for the connecting device. The first inner stiffener plate is fixed inside the lower ring to enhance its structural strength. At the same time, it cooperates with the docking device through the slot. The second inner stiffener plate in the docking device is fixed inside the upper ring. The flower-shaped locking post at its lower end can accurately and tightly lock into the slot. The flower-shaped structure increases the contact points and area, providing stronger friction and interlocking force, making the initial connection between the upper and lower rings stable. The fixing ring between the connecting device and the docking device further strengthens the connection. In the actual operation of the packed tower, when facing the impact and vibration generated by high gas velocity, high liquid velocity or solid particle scouring, this stable structure can ensure that the Pall ring remains intact for a long time, avoid the separation of the upper ring 4 and the lower ring 5, reduce the problems of changes in gas-liquid flow path, decrease in mass transfer efficiency and channel blockage caused by Pall ring deformation or damage, reduce the frequency of shutdown maintenance and packing replacement, improve the reliability of the equipment, and save production costs and production cycle.

[0019] 2. In this invention, the cross-shaped and staggered arrangement of the No. 2 and No. 1 inner ribs, with their cross-shaped cross-section, greatly increases the specific surface area and mass transfer path of the gas-liquid contact. When the gas and liquid enter the packed tower and flow through the Pall rings, they first contact the inner walls of the upper and lower rings, and then enter the complex space formed by the staggered inner ribs. Here, the gas and liquid continuously change their flow direction, forming multiple branch flows and vortices, which enhances the dispersion and mixing effect of the gas and liquid. At the same time, because the upper and lower rings have the same diameter and are larger than the diameter of the fixed ring, the gas and liquid can form complex flow paths inside and between the rings, further promoting the dispersion and mixing of the gas and liquid, making the material exchange between the gas and liquid more complete, and realizing the gas-liquid mass transfer process more effectively. This improves the separation efficiency of the packed tower and meets the needs of efficient mass transfer separation in processes such as distillation, absorption, and desorption in chemical production.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Please see Figures 1-4 This utility model provides a technical solution:

[0029] A fluoroplastic Pall ring for a packed tower includes a lower ring body 5, a connecting device 1 fixedly connected to the inner side of the lower ring body 5, a docking device 2 snapped into the middle of the upper end of the connecting device 1, an upper ring body 4 fixedly connected to the outer side of the docking device 2, and a fixing ring 3 movably connected between the upper end of the connecting device 1 and the lower end of the docking device 2.

[0030] The diameter of the upper ring 4 is the same as the diameter of the lower ring 5, and both the diameter of the upper ring 4 and the lower ring 5 are larger than the diameter of the fixed ring 3.

[0031] In this embodiment, the connecting device 1 includes a first inner stiffening plate 11, with a slot 12 at the upper center of the first inner stiffening plate 11. The first inner stiffening plate 11 is fixedly connected to the inner side of the lower ring body 5. The docking device 2 includes a second inner stiffening plate 21, with a locking post 22 fixedly connected to the lower center of the second inner stiffening plate 21. The second inner stiffening plate 21 is fixedly connected to the inner side of the upper ring body 4. The position and size of the locking post 22 correspond to the position and size of the slot 12. The locking post 22 has a flower-shaped structure. The second inner stiffening plate 21 has a cross-shaped structure, just like the first inner stiffening plate 11. The structure of the second inner stiffening plate 21 is the same as that of the first inner stiffening plate 11 and they are staggered. The cross-sections of the second inner stiffening plate 21 and the first inner stiffening plate 11 have a star-shaped structure.

[0032] Through the above scheme: the lower ring 5, as the foundation of the entire Pall ring structure, provides a stable support frame for the internal connecting device 1. The first inner stiffener 11 in the connecting device 1 is fixedly connected to the inner side of the lower ring 5, which not only enhances the structural strength of the lower ring 5, but also provides a key connecting component for docking with the upper ring 4. The slot 12 opened in the middle of the upper end of the first inner stiffener 11 is an important structure for realizing the connection between the upper ring 4 and the lower ring 5. The docking device 2 is fixedly connected to the inner side of the upper ring 4. The second inner stiffener 21 in the docking device 2 plays the same role as the first inner stiffener 11, on the one hand, enhancing the structure of the upper ring 4. On the one hand, the strength is achieved by the locking post 22 fixedly connected to the middle of its lower end and engaging with the locking groove 12. Since the position and size of the locking post 22 correspond to the position and size of the locking groove 12, and the locking post 22 has a flower-shaped structure, the locking post 22 can be precisely and tightly locked into the locking groove 12 during assembly, thereby achieving the initial connection between the upper ring body 4 and the lower ring body 5. The second inner stiffening plate 21 and the first inner stiffening plate 11 are both designed with a cross-shaped structure, and their structures are the same and staggered, with a cross-shaped structure. This unique structural design greatly changes the flow state of gas and liquid in the Pall ring. When gas and liquid enter the packing When the gas and liquid flow through the Pall rings in the packed tower, they first come into contact with the inner walls of the upper ring 4 and the lower ring 5, and then enter the complex space formed by the interlaced inner ribs. Within this space, the gas and liquid continuously change their flow direction, forming multiple branch flows and vortices. The design of the flower-shaped retaining post 22 and the retaining groove 12 greatly enhances the stability of the connection between the upper ring 4 and the lower ring 5. Compared to ordinary columnar structures, the flower-shaped structure has more contact points and a larger contact area, providing stronger friction and interlocking force, making the retaining post 22 less prone to loosening within the retaining groove 12. During the operation of the packed tower, the gas and liquid flow will... The Pall ring experiences a certain amount of impact and vibration. The robust connection structure ensures that the Pall ring maintains its integrity even under long-term external forces, preventing the upper ring 4 from separating from the lower ring 5. This guarantees the normal operation of the Pall ring in the packed tower. The structure of the second inner stiffener 21 and the first inner stiffener 11 not only enhances the structural strength of the ring but also further assists in the connection between the upper ring 4 and the lower ring 5. Their staggered distribution makes the entire Pall ring structure more compact and stable, better resisting the impact and vibration caused by gas-liquid flow, and further improving the reliability of the connection.

[0033] It should be noted that this utility model is a fluoroplastic Pall ring for a packed tower. During use, the first inner stiffener plate 11 of the connecting device 1, which is fixedly connected to the inner side of the lower ring body 5, provides basic support for the overall structure. The slot 12 at the upper center of the first inner stiffener plate 11 is used to cooperate with the docking device 2. The second inner stiffener plate 21 of the docking device 2 is fixed to the inner side of the upper ring body 4. The position and size of the locking post 22 at the lower center of the second inner stiffener plate 21 correspond to the slot 12, and the locking post 22 has a flower-shaped structure, which can be tightly locked in the slot 12 to achieve the initial docking of the upper ring body 4 and the lower ring body 5. At the same time, both the second inner stiffener plate 21 and the first inner stiffener plate 11 have a cross-shaped structure, and The rings are staggered, with their cross-sections forming a star-shaped structure. This design increases the specific surface area and mass transfer path for gas-liquid contact, improving mass transfer efficiency. Furthermore, a fixed ring 3 is movably connected between the upper end of the connecting device 1 and the lower end of the docking device 2, further reinforcing the connection between the upper ring 4 and the lower ring 5 and ensuring structural stability. The upper ring 4 and the lower ring 5 have the same diameter, both larger than the diameter of the fixed ring 3, allowing the gas and liquid to form complex flow paths inside and between the rings when flowing through them. This enhances the dispersion and mixing of the gas and liquid, thereby more effectively realizing the gas-liquid mass transfer process and improving the separation efficiency of the packed tower.
