Abstract

The invention relates to a random packing tower for high-precision separation. The random packing tower comprises a tower body, a tower bottom and a condensing unit, wherein the tower body comprises multiple packing sections which are connected one another, the packing sections are filled with random packing, an isolating layer is arranged at the inner bottom of each packing section, exchange holes are formed in the surfaces of the isolating layers, and diameter of the exchange holes is smaller than outer diameter of the random packing; the random packing is of a hollow hexagonal spirochete structure, and the cross section of the random packing is in a regular hexagon shape. Compared with traditional spherical or other shaped random packing, the packing has higher space utilization rate when filled in unit space, a gap between the random packing is reduced, and mass transfer dead zones are reduced; the random packing is of the hollow hexagonal spirochete structure and is formed by metal wires through bending and winding, so that a liquid can be well dispersed to form a film, the packing surface is easily wet by the liquid, a better gas-liquid channel and mass transfer surface are obtained, a gas-liquid contact area is increased, and heat and mass transfer efficiency is further improved.

Description

Technical field [0001] The invention relates to the technical field of rectification, in particular to a random packed tower for high-precision separation. Background technique [0002] As an important unit equipment in oil refining, petrochemical, fine chemical, food, medicine, environmental protection and other industries, rectification tower is widely used in rectification, absorption, extraction, washing, heat transfer and other unit operations. The rectification tower can be divided into plate towers. And packed tower. In the plate tower, the gas-liquid phases are in countercurrent contact plate by plate in the tower, while the gas-liquid phases of the packed tower are in continuous differential countercurrent contact along the height of the packing layer in the tower. Packing is the main component of the packed tower. Packing can be divided into random packing and structured packing. Among them, random packing is a kind of packing that is widely used. It is generally compo...
