rotary vacuum evaporator


Molecular distillation system is a kind of thermodynamics separation technique, which USES the mixed liquid or liquid - solid system components in the boiling point is different, make the low boiling point components to rotary vacuum evaporator evaporation, condensation, to separate the components. Compared with extraction and filtering crystallization separation process, the advantages of molecular distillation system is no need to use other system components solvent, avoid introducing new material. The category of the many molecular distillation system, the most common have atmospheric pressure, stress and pressure, where is the difference between them? How do you understand us? Under the condition of close to the atmosphere pressure, liquid mixture is heated, due to the volatility of components are different, one of the more volatile component after vaporization, then condensation, can realize the separation of the mixture. Because the whole process of molecular distillation system are conducted under atmospheric pressure, so called the atmospheric molecular distillation system.
As tower equipment is mainly used in mass rotovap distillation transfer process, you must quickly two phase can be fully contact, in order to obtain higher mass transfer efficiency, besides should satisfy the technological conditions, also should satisfy the following basic requirements:
1. The production capacity. On cross section per unit time per unit of tower materials processing. In larger gas and liquid flow rate, still do not know happen a lot of smuggled with foam fog, such as block liquid or liquid flood damage phenomenon of normal operation.
2. High separation efficiency. The gas and liquid phase can be fully contact and separation effect is good.
3. Large elasticity of operation. Have strong adaptability and wide operating range. Can adapt to different properties of materials and the load fluctuation can maintain stable operation, there is still a high separation efficiency.
4. The pressure drop is small. The wiped film distillation fluid through the small resistance, which can greatly save the power consumption of production, reduce costs, if excessive pressure drop in the decompression tower system will be difficult to maintain the necessary degree of vacuum.
5. Simple structure, material consumption, easy to manufacture and installation, which can reduce investment, reduce the cost.
6. Corrosion resistance is not easy to jam, easy for operation, adjustment and maintenance
