Short-path distillation equipment is a new apparatus produced by our company according to the demand of the market. This apparatus, characterized by simple structure, less land occupation, high evaporation and recovery efficiency, is mainly used in fractional distillation. Fractional distillation is a process to separate compounds with different boiling point in some mixtures. During the process, the mixtures are heated, and the objected substance is separated according to the difference of matters in the mixtures. The process is physical change because there isn’t new substance produced. Fractional distillation is actually multiple distillation that is suitable for separation and purification of liquid organic mixtures with little difference in boiling point, such as fractional distillation of coal tar and petroleum. When the boiling point of the reaction is closer than 20 degree, the fractional distillation is more suitable than simple distillation.Fractional column in the short-path distillation equipment can provide a big cooling area.Fractionation is the process of multiple gasification-condensation in a single operation using a fractional column.Therefore, fractionation is actually multiple distillation. It is more suitable for separating and purifying liquid organic mixtures with little difference in boiling point.
the column cylinder equipped with outside heating mantle, rotor and inside condenser. The fixing frame of rotor is precisely equipped with scratch film and anti-splash device. The inside condenser is placed in the center of evaporator, and the rotor should rotor between column cylinder and condenser.
The material should add from the top of evaporator and continuously spread to the heating surface through the material covered on rotor. Then, the scratch film is capable of scratching the material into a thin and flowing liquid film. During this process, the light molecular exceeded the heating surface form the condense liquid on inside condenser without any collision. Then, the molecular flows along the condenser tube, and discharge through the discharge tube on the bottom of evaporator. The residue liquid (heavy molecule)is collected on the circular channel under the heating zone, and flows through the discharge tube on one side.
