Description

Technical Field

[0001] This utility model relates to the field of liquid redistributor technology, and in particular to a large-scale tower-based collection and redistributor. Background Technology

[0002] Liquid collectors and redistributors are crucial components within packed towers. For large packed towers with diameters exceeding three meters, the large diameter and area of ​​the tower necessitate a large cross-sectional area for the distributor. Therefore, it is essential to maintain a level bottom for consistent liquid levels. Currently, a support beam is used to hold the bottom of the distributor in place to control its levelness. However, the large surface area of ​​the support beam can obstruct liquid distribution, affecting even the upward flow of gas, and thus requires improvement. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the prior art, this utility model provides a large tower in-collection redistributor, which aims to avoid the support structure blocking the liquid distribution of the distributor.

[0004] Technical solution: To achieve the above objectives, the present invention provides a large tower-based collection and redistribution device, which includes a distributor installed inside a packed tower. A support body is also installed inside the packed tower, with the support body positioned above the distributor. The support body has multiple downward-extending lifting assemblies, the lower ends of which are connected to the distributor.

[0005] Furthermore, the support body has a perforated structure for gas flow, and the support body and the distributor are spaced apart.

[0006] Furthermore, the support is a beam frame, with both ends of the beam frame overlapping the supports on the inner wall of the packed tower.

[0007] Furthermore, the upper end of the lifting assembly is fixedly connected to the support body.

[0008] Furthermore, the upper end of the lifting assembly is movably connected to the support body, making the height of the lifting assembly adjustable to level the distributor.

[0009] Furthermore, a hanging plate is installed on the support body, and a through hole is opened on the hanging plate; a bolt is provided at the upper end of the lifting assembly, and the bolt passes through the through hole and is connected to a nut; when the nut rotates on the bolt, the height of the lifting assembly is adjusted.

[0010] Furthermore, the distributor is provided with a plurality of air risers; the lower end of the lifting assembly extends into the gap between adjacent air risers, and the lower end of the lifting assembly is connected to the outer wall of the air riser.

[0011] Furthermore, a lifting ring is provided at the lower end of the lifting assembly, and a hook is provided on the outer wall of the air riser; the hook hooks onto the lifting ring, so that the lower end of the lifting assembly is connected to the outer wall of the air riser.

[0012] Furthermore, the lower end of the lifting assembly is connected to the base plate of the distributor.

[0013] Furthermore, the base plate of the distributor is composed of several panels, and a connecting plate is provided at the joint of the panels, with connecting holes provided on the connecting plate; the lower end of the lifting assembly is provided with a hook, which hooks into the connecting holes of two adjacent connecting plates.

[0014] Beneficial effects: The beneficial effects of this utility model's large-scale tower internal collection and redistribution device are as follows:

[0015] 1) A support body is installed above the distributor, and the distributor is suspended by multiple downward-extending suspension components on the support body, so that the bottom of the distributor can be kept on the same horizontal plane, and the support body and suspension components will not affect the liquid distribution of the distributor;

[0016] 2) The support is a beam frame, and the distance between the beam frame and the distributor is large, which does not hinder the rise of gas. There is basically no pressure drop when the gas passes through the beam frame. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] As attached Figures 1 to 4 The large-scale tower-based liquid redistributor includes a distributor 1 installed inside a packed tower. A support body 2 is also installed inside the packed tower, positioned above the distributor 1. The support body 2 has multiple downward-extending lifting assemblies 3, the lower ends of which are connected to the distributor 1. The multiple lifting assemblies 3 hold different parts of the distributor 1, ensuring the distributor 1 maintains a good level. Because the support body 2 is located above the distributor 1, it does not obstruct the liquid distribution within the distributor 1.

[0023] There are several liquid distribution holes on the distributor 1. When the levelness of the distributor 1 is poor, the flow rate of each liquid distribution hole will be different, which will affect the liquid distribution effect of the distributor 1.

[0024] During the operation of distributor 1, liquid flows from top to bottom and gas flows from bottom to top. The support 2 has a perforated structure to allow gas flow, and the support 2 is spaced apart from distributor 1 to reduce obstruction of gas rise. Specifically, as shown in the attached diagram... Figure 2 As shown, the support 2 is a beam frame, which consists of three triangularly arranged crossbeams 10. Multiple connecting rods connect adjacent crossbeams 10. This triangular beam frame structure has a large gas passage, resulting in virtually no pressure drop as gas passes through it. Furthermore, the beam frame structure is positioned above the distributor, neither affecting gas distribution nor hindering liquid injection. Both the crossbeams 10 and the connecting rods are hollow tubes to reduce the weight of the beam frame. Two supports 4 are arranged opposite each other on the inner wall of the packed tower. The two ends of the beam frame are fixedly connected to the two supports 4, which provide support for the beam frame.

[0025] The distributor 1 in this invention is suitable for large packed towers with a diameter of three meters or more, and can also be used for large packed towers with a diameter of ten meters or less. Multiple lifting assemblies 3 can be installed on the beam frame, and the number of lifting assemblies 3 can be adjusted adaptively according to the diameter of the packed tower.

[0026] In one embodiment, the upper end of the sling assembly 3 is fixedly connected to the support body 2.

[0027] In one embodiment, the upper end of the lifting assembly 3 is movably connected to the support body 2, making the height of the lifting assembly 3 adjustable to level the distributor 1 and adjust the bottom of the distributor 1 to the same horizontal plane. Specifically, a hanging plate 5 is installed on the support body 2, and the hanging plate 5 has through holes, as shown in the attached figure. Figure 3 As shown, the two sides of the suspended platform 5 are respectively attached to two crossbeams 10. A bolt 6 is provided at the upper end of the lifting assembly 3, and the bolt 6 passes through the through hole and is connected to a nut 7. The height of the lifting assembly 3 is adjusted by rotating the nut 7 on the bolt 6.

[0028] One implementation, for example, is attached. Figure 3As shown, the distributor 1 includes a base plate 9, on which several air risers 8 are arranged. Each air riser 8 is a vertically penetrating pipe with an internal gas rising channel. The lower end of each air riser 8 is fixedly connected to the base plate 9, and the upper end of each air riser 8 is provided with a liquid collecting angle steel 16. The liquid collecting angle steel 16 is spaced apart from the air riser 8, forming gas outlets on both sides of the upper opening of the air riser 8. The lower end of the lifting assembly 3 extends into the gap between adjacent air risers 8, and the lower end of the lifting assembly 3 is connected to the outer wall of the air riser 8. Specifically, the lower end of the lifting assembly 3 is provided with a lifting ring 11, and the outer wall of each air riser 8 is provided with a hook 12. The hook 12 is a U-shaped hook, and its two sides are fixed to the outer walls of the air risers 8 on both sides by welding or bolting. The hook 12 hooks onto the lifting ring 11, connecting the lower end of the lifting assembly 3 to the outer wall of the air riser 8. The lifting assembly 3 holds the air riser pipe 8, indirectly providing tension to the base plate 9 of the distributor 1.

[0029] One implementation, for example, is attached. Figure 4 As shown, the lower end of the lifting assembly 3 is connected to the base plate 9 of the distributor 1. Specifically, the base plate 9 of the distributor 1 is composed of several panels 13 spliced ​​together. A connecting plate 14 is provided at the splicing point of the panels 13. The panels 13 are horizontal plates, and the connecting plate 14 is a vertical plate. A horizontal connecting hole 15 is opened on the connecting plate 14. The locking bolt 6 passes through the connecting holes 15 on two connecting plates 14 at the same time, thereby splicing the two panels 13 together. The lower end of the lifting assembly 3 is provided with a hook 16. The hook 16 is hooked into the connecting holes 15 of two adjacent connecting plates 14, and the opening of the hook 16 is tied with steel wire to prevent the hook 16 from detaching from the connecting plate 14.

[0030] One working method of this utility model is as follows: install a support 4 above the distributor 1 in the packed tower, then fix the two ends of the assembled beam frame to the two supports 4 respectively, then attach the hanging plate 5 to the two crossbeams 10 of the beam frame, fix the lower end of the lifting assembly 3 to the bottom plate 9 or the air riser 8 of the distributor 1, and then adjust the height of the lifting assembly 3 by the nut 7, thereby adjusting the bottom of the distributor 1 to the same horizontal plane.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
