Description
Technical Field
The utility model relates to a scrape board-like mixed molecule separation technical field, concretely relates to mixed type molecule evaporimeter.
Background
Molecular Distillation (Molecular Distillation) is a highly new liquid-liquid separation technology which is being developed and applied industrially at home and abroad, and substances are separated by utilizing the difference of Molecular motion mean free path under the condition of being far lower than a boiling point. The molecular distillation has simplified internal parts and very small internal pressure drop, can obtain very high vacuum degree, enables the materials to be separated at the temperature far lower than the normal pressure boiling point of the materials, is an evaporation process without boiling, and is particularly suitable for the special separation of high-boiling-point heat-sensitive substances and natural products.
The separation rationale is the same regardless of the type of molecular distillation apparatus used at present. Namely, the liquid molecule can escape from the liquid surface when heated, and the average free path of different kinds of molecules is different after the molecules escape. Langmuir proposes a mathematical model of the mean free path of molecular motion according to the kinetic theory of ideal gases: λ m is k2 × pi × Td2 × p- (1).
In the formula: lambda m-molecular motion mean free path; d-the effective diameter of the molecule; the pressure of the environment in which the p-molecule is located; the temperature of the environment in which the T-molecule is located; k-boltzmann constant. From the formula (1), the temperature, pressure and effective diameter of the molecule are the main factors affecting the mean free path of molecular motion. Under certain conditions of temperature and pressure, different molecules have different mean free paths due to different effective diameters, that is, the flight distances of different molecules which do not collide with other molecules after escaping from the liquid surface are different. The average free path of the light molecules is large, the average free path of the heavy molecules is small, a condensing surface is arranged at a position which is far away from the liquid surface and is smaller than the average free path of the light molecules and larger than the average free path of the heavy molecules, so that the light molecules are condensed on the condensing surface, and the heavy molecules return to the liquid surface because the heavy molecules cannot reach the condensing surface, and thus the mixture is separated. At present, conventional parameter control such as acquisition of high vacuum and quality of film formation has been developed to a desirable level, but the separation efficiency of molecular distillation cannot be improved greatly.
