Description

Vacuum rectification reflux tank

Technical Field

Background

Distillation is a thermodynamic separation process that utilizes the difference in boiling points of components in a mixed liquid or liquid-solid system to vaporize lower boiling components and recondense to separate the entire component, a unit operation that combines the two unit operations of evaporation and condensation. Compared with other separation means, such as extraction, filtration crystallization and the like, the method has the advantage that other solvents except system components are not required, so that new impurities are not introduced. The mixed liquid is boiled and the steam enters the fractionating column to be partially condensed, the condensate is contacted with the steam which continuously rises on the way of descending, the steam and the steam exchange heat, the high boiling point component in the steam is condensed, the low boiling point component still rises as the steam, the low boiling point component in the condensate is heated and gasified, and the high boiling point component still falls as a liquid. The result is an increase in the low-boiling components in the rising vapor and an increase in the high-boiling components in the falling condensate. Thus, after heat exchange for many times, the method is equivalent to continuous ordinary distillation for many times. So that the vapor of the low-boiling components rises continuously and is distilled out; the high-boiling components are continuously returned to the distillation flask, so that they are separated.
