Description

Technical Field

[0001] The utility model relates to the technical field of packed towers, in particular to a redistributor for a packed tower. Background Art

[0002] The packed tower is a widely used chemical separation device in the petrochemical industry. Since the last century, people have started to study it. However, due to the imperfect packed tower and its internals at that time, the development of the packed tower was greatly restricted. In the past decade or more, with the development of separation technology, the structure of the packing has been continuously improved, and many new types of packed towers have emerged.

[0003] When the packed tower needs to be stacked in sections, a liquid redistributor must be set. The reason for stacking in sections is either due to the need for intermediate feeding; or the height of the packing layer is too large, which will not only lead to poor distribution of the fluid volume but also cause uneven distribution of components on the same cross-section, thus reducing the separation efficiency of the packed tower. Currently, the liquid redistributor itself diverts the flow through the triangular grooves opened on the plate wall, and the thickness of the plate of the redistributor itself is general. After more liquid flows in, it is easy to cause the plate wall to shake, resulting in poor liquid distribution effect.

[0004] Therefore, it is necessary to provide a new redistributor for a packed tower to solve the above technical problems. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides a redistributor for a packed tower.

[0006] The redistributor for a packed tower provided by the utility model includes a distributor main body. A plurality of rectangular frame parts communicating with the distributor main body are arranged on both sides of the distributor main body, and L-shaped diversion pipes are arranged on both side walls of the rectangular frame parts.

[0007] The horizontal ports of the L-shaped diversion pipes communicate with the liquid flow ports opened on the rectangular frame parts. Side flow shells are respectively fixedly connected to both sides of the vertical section of the L-shaped diversion pipes. Liquid dropping ports are opened on both sides of the side flow shells close to the bottom, and a liquid inlet is opened on the pipe part of the side flow shell connected to the L-shaped diversion pipe.

[0008] Preferably, the liquid inlet is located in the upper half of the side flow shell.

[0009] Preferably, a shunt box is fixedly installed in the distributor main body.

[0010] Preferably, a zigzag groove in the shape of a "mouth" is opened at the opening at the top of the shunt box.

[0011] Preferably, the length of the rectangular frame parts arranged on the distributor main body decreases from the middle to both sides.

[0012] Preferably, the bottom of the L-shaped flow guide pipe is fixedly welded to the outer wall of the rectangular frame portion.

[0013] Compared with the related art, the redistributor for the packed tower provided by the utility model has the following beneficial effects:

[0014] The utility model fixes the distributor body in the packing tower, and the fallen materials can flow into the diversion box for concentration. When the diversion box is full, the materials are diverted to the surrounding distributor bodies by the sawtooth grooves. Subsequently, the material capacity in each rectangular frame part rises to the liquid flow port and is diverted to each L-shaped guide pipe. The materials are then divided by the liquid drop ports opened on the side flow shells of each L-shaped guide pipe, thereby guiding the liquid in the packing tower well. At the same time, the L-shaped guide pipe arranged on the outer wall of the rectangular frame part can also play the role of reinforcing ribs, which greatly improves the strength of the distributor body itself.

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0021] See also Figures 1 to 3 An embodiment of the utility model provides a redistributor for a packed tower, and the redistributor for a packed tower comprises: a distributor body 1 and an L-shaped flow guide pipe 2.

[0022] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 and Figure 3, on both sides of the distributor body 1, a plurality of rectangular frame parts 11 communicating with the distributor body 1 are provided, and the length of the rectangular frame parts 11 provided on the distributor body 1 decreases from the middle to both sides. On both side walls of the rectangular frame part 11, L-shaped diversion pipes 2 are provided. The horizontal ports of the L-shaped diversion pipes 2 communicate with the liquid flow ports opened on the rectangular frame part 11. The bottom of the L-shaped diversion pipe 2 is fixedly welded to the outer wall of the rectangular frame part 11. On both sides of the vertical section of the L-shaped diversion pipe 2, side flow housings 21 are respectively fixedly connected. On both sides near the bottom of the side flow housing 21, liquid dropping ports 21b are opened. On the pipe body part of the side flow housing 21 connected to the L-shaped diversion pipe 2, a liquid inlet 21a is opened. The liquid inlet 21a is located in the upper half of the side flow housing 21;

[0023] A shunt box 3 is fixedly installed in the distributor body 1, and a zigzag groove 3a in the shape of a "mouth" is opened at the opening at the top of the shunt box 3.

[0024] It should be noted that: the distributor body 1 is fixed in the packing tower, and the falling materials can flow into the shunt box 3 for concentration. When the shunt box 3 is full, it is shunted to the distributor body 1 around by each zigzag groove 3a. Subsequently, the material volume in each rectangular frame part 11 rises to the liquid flow port and is shunted into each L-shaped diversion pipe 2. Then, the liquid is distributed through the liquid dropping ports 21b opened on the side flow housings 21 of each L-shaped diversion pipe 2. Thus, the liquid in the packing tower can be well guided. At the same time, the L-shaped diversion pipes 2 provided on the outer wall of the rectangular frame part 11 can also play the role of reinforcing ribs, greatly improving the strength of the distributor body 1 itself.
