Problems solved by technology

For high-efficiency rectification columns of 20mm~50mm, the column is filled with high-efficiency granular packing such as θ mesh rings and spiral wires. After the diameter of the rectification column with particle packing is enlarged to 200mm, the efficiency of the column drops rapidly, and the separation efficiency is lower than that of the corrugated structured packing column with the same column diameter.

Embodiment Construction

[0009] According to the accompanying drawings, the filler of the high-efficiency rectification packed tower of the present invention is composed of several meshed spiral tubes 1 connected in parallel, and the axis of the spiral tube is placed parallel to the axis of the packed tower. The invention adopts a parallel spiral structure, and a group of several mesh spiral pipes are connected in parallel and installed in the tower section to form a parallel spiral packed tower. The spiral tube is made of mesh belt material. There is a spiral gap between the upper and lower adjacent spiral coils of the rolled spiral tube. There is a spring sheath 2 outside a single spiral tube, and the spiral tubes are separated by the spring sheath. Open and form a parallel structure.

[0010] The present invention carries out rectification test with ethanol-water solution system, and the height of the parallel spiral packing used in test is 1000mm, and diameter is 500mm, and under the condition of ...

Abstract

The invention is a packed tower with high effective distillation, comprising the tower shell and the filler, the said filler is paralleled formed by several netted spiral pipes, and the place of axial cord in the spiral pipe is parallel to that of packed tower. The said spiral pipe is prepared by net tape material. There is spiral slit in the up and down of the spiral pipe and between the near spiral ring. The outer ring of each spiral pipe is equipped with spring protective housing. The invention not only effectively solves the scale effect problem of the high effective distillation packed tower, but also can still maintain high effective separation efficiency after the tower diameter is enlarged.

Description

1. Technical field: [0001] The invention relates to a rectification tower structure, and in particular discloses a high-efficiency rectification packed tower. 2. Background technology: [0002] At present, the problem of the amplification effect of the high-efficiency distillation column has not been well resolved. For high-efficiency rectification columns of 20mm~50mm, the column is filled with high-efficiency granular packing such as θ mesh rings and spiral wires. When the diameter of the particle packed rectification column is enlarged to 200mm, the efficiency of the column drops rapidly, and the separation efficiency is lower than that of the corrugated structured packing column with the same column diameter. 3. Contents of the invention: [0003] The purpose of the present invention is not only to effectively solve the amplification effect problem of the high-efficiency rectification tower, but also to maintain the high-efficiency separation efficiency of the tower...
