Description

technical field [0001] The invention relates to distillation technology in the technical fields of chemical industry, medicine and food production, in particular to an intelligent reflux ratio distillation device. Background technique [0002] Distillation is a thermodynamic separation process that utilizes the different boiling points of components in a mixed liquid or liquid-solid system to evaporate low-boiling components and then condense them to separate the unit operations of the entire components. The distillation device is an industrial device to complete this separation process. In production practice, the distillation device vaporizes the desired fractions during heating according to the different boiling points of the fractions, and then condenses the high fractions, middle and low fractions of the mixture in industrial production. Leave. For example, separate high-concentration and high-purity alcohol from low-concentration alcohol solution (containing other fus...
