The method and apparatus of property mixture.
Background technology
In chemical process, it is often necessary to face the separation of gas and liquid mixture, common separation method packet
Include extraction, absorption, distillation, absorption etc., wherein distillation have been developed more than 200 years, be in industry most important separation means it
One, principle is different according to the boiling point of each component in mixture, and the component of low boiling point is distilled out of and condenses, and the group that boiling point is high
Divide and then stay in system, to achieve the purpose that separation.
However, conventional distillating method cannot be satisfied the requirement of high purity product, and energy consumption is big, is not suitable for nearly boiling point body
It is the separation of mixture；For azeotropic mixture, then component can not be made to be kept completely separate.Therefore, it is necessary to special rectificating methods to reach
To the purpose of idetified separation.

Source, under different vacuum degrees, the separated object matter different to dielectric constant heats, and passes through the cold end pair insensitive to microwave
It distillates some vapor and carries out cooling collection, realize the separation of high-k and low-k mixture.But whole operation category
It in batch process, needs to be put into the heated perimeter of microwave source after liquid film is placed in closed reagent bottle every time, operation is excessively numerous
It is trivial, it cannot achieve the NATURAL DISTRIBUTION of liquid.
Patent CN206404364U proposes a kind of microwave separation extraction equipment, solves raw extract in the prior art
Manufacturer because leading to the problem of extract quality difference using Resistant heating or gas heating, provided with microwave generator
Microwave is generated to heat raw material.But it underuses the advantage that microwave selectively heats different dielectric property,
And retort is integrally placed under microwave radiation and is heated, it is that liquid is not evenly dispersed, greatly reduce the efficiency of heating surface.
