Background

Molecular distillation is a special liquid-liquid split technology, which is different from traditional distillation and relies on the principle of boiling point difference separation, but relies on the difference of different substance molecular motion mean free path to realize separation. When the liquid mixture flows along the heating plate and is heated, light and heavy molecules can escape from the liquid surface and enter the gas phase, because of different free paths of the light and heavy molecules, the molecules of different substances move for different distances after escaping from the liquid surface, if a condensing plate can be properly arranged, the light molecules reach the condensing plate and are condensed and discharged, and the heavy molecules cannot reach the condensing plate and are discharged along the mixed liquid, so that the aim of separating the substances is fulfilled. The advantages of molecular distillation are: the distillation temperature is low, the molecular distillation is operated at a temperature far lower than the boiling point, and the separation can be achieved as long as the temperature difference exists, which is the essential difference between the molecular distillation and the conventional distillation; the distillation vacuum degree is high, the molecular distillation device can obtain high vacuum degree in the molecular distillation device, and the molecular distillation is usually operated under low pressure, so that materials are not easy to oxidize and damage; the distilled liquid film is thin, and the heat transfer efficiency is high; the heating time of the material is short, the distance between the heated liquid surface and the condensing surface is less than the mean free path of the light molecules, so the light molecules escaping from the liquid surface almost reach the condensing surface without collision, therefore, the heating time of the distillation material is short, the retention time at the distillation temperature is generally between several seconds and dozens of seconds, and the chance of material decomposition is reduced; the separation degree is higher, and the molecular distillation can separate substances which are not easy to separate conventionally.

Among the prior art, condensing equipment generally adopts is whole liquid chamber, can store a large amount of condensing medium, has nevertheless also caused the waste simultaneously, and some condensing medium prices are more expensive, and a large amount of uses can increase the cost, and the use of another kind of condensing medium can be influenced in the remaining of another kind of condensing medium, the effect of condensing promptly, therefore the clearance of later stage condenser pipe also is a problem that needs to solve.
