Honeycomb tower distributor

Abstract

The invention discloses a honeycomb tower distributor. The honeycomb tower distributor is correspondingly installed on a honeycomb pipe, the center of the honeycomb tower distributor is aligned with the center of the honeycomb pipe on the lower side, the honeycomb tower distributor comprises a distribution pipe and distribution holes, the distribution pipe is cylindrical, the multiple distribution holes are formed in the pipe wall of the distribution pipe in the circumferential direction, and the size and the number of the distribution holes ensure that the distance between the liquid level of the honeycomb tower distributor and the center of the distribution holes is 20-500mm. The technical problem that in the prior art, liquid flowing down from all distributors is inconsistent is solved, after the distributors are additionally arranged on all honeycomb pipe sections, liquid flowing down from an upper tower section is evenly distributed into all the honeycomb pipes through the distributors,and the flow of the liquid obtained by all the honeycomb pipes is equal, so that the separation effects of all honeycomb pipes are ensured to be the same, and the separation effect of the whole honeycomb tower section is in a normal state. All honeycomb tower sections can work normally so as to guarantee that the whole tower can work normally.

Description

technical field [0001] The invention relates to a honeycomb tower distributor, which belongs to the technical field of distributors. Background technique [0002] In the process of separating boron isotopes by boron trifluoride low-temperature rectification in the honeycomb tower, the honeycomb tubes are filled with high-efficiency random packing (generally filled with θ rings), and the nominal diameter of the honeycomb tube and the nominal diameter of the packing are within a reasonable range. The sum of capacity can meet the needs of industrial-scale production, and can solve the problem of the high temperature of the boron trifluoride low-temperature rectification separation boron isotope tower. In order to obtain a high-efficiency separation effect by installing high-efficiency random packing in the honeycomb tower, the liquid under the throttling of the previous tower should be evenly distributed to each honeycomb tube. Reasonable design of the structure of the liquid ...

AI Technical Summary

Problems solved by technology

[0003] Separation tower without distribution plate and distributor honeycomb tube, due to equipment processing quality problems and installation problems, the equipment is tilted (such as figure 1 ), there will be two unfavorable situations

One is that the inclination is large, which will cause the liquid to flow to one side. Some honeycomb tubes are filled with liquid, and some will produce empty tubes.

The second is that the inclination is small, which will also cause some honeycomb tubes to have a large liquid flow and some small flow phenomena.

There are many problems such as the processing quality of the distribution holes on many distributors, the welding of the distributor and the distributor support plate, etc. It is difficult to ensure that the distribution holes on each distributor are on a horizontal line, and the distribution between the distributors Holes are prone to height differences

However, the support plate liquid on the distributor is on a plane, so that the amount of liquid flowing down from each distributor will deviate, making the liquid flow in each honeycomb tube inconsistent, affecting the separation effect of the honeycomb pipe section, and ultimately affecting the entire tower The separation effect, the separation ability of the whole tower is greatly reduced
