Abstract

The invention relates to a combined rectifying column and application thereof, in particular to a combined rectifying column which is characterized by comprising an outer column body, a middle casing pipe and an inner casing pipe, wherein the main body parts of the outer column, the middle casing pipe and the inner casing pipe are tubular parts which are arranged with a same axis center. The invention further relates to a rectifying device with the combined rectifying column, and a method for rectifying a material to be rectified by using the combined rectifying column and the rectifying device. The device and the method provided by the invention have the characteristics that the washing is easy, the replacement is convenient when multiple fillers are used, the purity of a product is high, the quality is stable, the rectification yield is relatively high, the separation cost is low, and no potential safety hazard is generated in the rectification process, and moreover the types and the use amounts of the fillers can be changed according to different demands, so that the combined rectifying column has multiple functions of solvent purification and recycling, natural production extraction, and the like.

Description

technical field

[0001] The present application relates to a compound separation and purification device in the field of chemistry and chemical engineering, in particular to components for rectification and a combined multipurpose rectification device using the components, as well as their applications. Background technique

[0002] Rectification is a distillation method that uses reflux to obtain high-purity separation of liquid mixtures. Its basic principle is to partially vaporize the liquid mixture, and use the characteristics of different volatilities (relative volatility) of each component to achieve the unit operation for separation purposes. . A rectification tower is a tower-type vapor-liquid contact device for rectification, also known as a distillation tower. Traditionally, the industrial large-scale rectification device is called a rectification column, and the small-scale rectification device in the laboratory is called a rectification column. At present, most ...
