Molecular distiller principle and its operating precautions

As a special liquid separation technology, molecular distillation is different from the separation principle of the traditional distillation boiling point difference, which relies on the difference in the average free path of molecular motion of different substances to achieve separation
.

That is, when the liquid mixture flows along the hot plate and is heated, the molecules will escape from the liquid level and enter the gas phase, because the freedom path of different molecules is different, so the molecules of different substances move at different distances after escaping from the liquid level, the light molecules reach the condensation plate discharge, and the heavy molecules are discharged
along the mixed liquid.

In this way, the purpose of
material separation is achieved.

Molecular distiller principle: Molecular distillation is a distillation method operated under high vacuum, because the average free path of the vapor molecules is greater than the distance between the evaporation surface and the condensing surface, so the difference in the evaporation rate of each component can be used to separate
the liquid mixture.

Molecular distillation operation precautions: 1, molecular distillation device needs to strictly control the liquid level of each effect separator, so that it is in the position
of use requirements.

2.
When the molecular distillation device is easy to precipitate the crystallized material, it is easy to block the pipeline, plate evaporator, valve, etc.
, and it is necessary to use vacuum extraction or regular water flushing to keep it open
.

3.
Frequently adjust the molecular distillation device instrumentation to make it sensitive and reliable
.

If the instrument is found to be malfunctioning, it should be dealt with
in time.

4, molecular distillation device needs to often carry out strict inspection of equipment, pipelines, is the mirror glass to be replaced in a timely manner, in order to prevent accidents
caused by corrosion.

5.
Before overhauling the equipment, the pressure discharge should be discharged, and the water should be rinsed and cooled down to remove the remaining corrosive liquid
in the equipment.

6.
The operator should wear protective clothing to avoid personal injury
caused by high temperature liquid and steam.
