Problems solved by technology

[0003] At present, most of the vacuum units used in this system are rotary vane pumps connected in series with Roots vacuum pumps. The advantage of this vacuum system is that it can pump the vacuum of the system to 0.1Pa. However, the disadvantage of this vacuum pump is that moisture or other volatile components Substances entering the vacuum pump oil will affect the emulsification of the vacuum pump oil, greatly reduce the vacuum degree of the system, and also affect the stability, normal operation and service life of the vacuum pump

Abstract

The invention discloses a vacuum system for a thin film evaporation-rectification coupled device. The vacuum system comprises a vacuum pump, one end of the vacuum pump is connected to a thin film evaporation-rectification coupled device system by a pipe, the other end of the vacuum pump is connected to a receiver by a pipe, a buffer tank is arranged between the thin film evaporation-rectification coupled device system and the vacuum pump, and the receiver is provided with a condenser. The vacuum system is connected to the thin film evaporation-rectification coupled device system. A small amount of water and volatile components are pumped by the dry screw-type vacuum pump and then are cooled by a cooler so that the influence produced by a trace amount of water or an insoluble material on the system vacuum degree is avoided completely. The vacuum system maximumly realizes volatile component recovery and guarantees vacuum stability of the thin film evaporation-rectification coupled device system.

Description

technical field [0001] The invention relates to a vacuum system, in particular to a vacuum system used for coupling equipment of thin film evaporation and rectification. Background technique [0002] The new separation device coupled with molecular distillation and conventional vacuum distillation technology has been widely used in natural products, heat-sensitive fine chemicals, etc., such as the purification of EPA, DPA and DHA in the production of seal oil, the separation of cinnamaldehyde and cinnamyl acetate, etc. , will use the coupling device of molecular distillation and conventional vacuum distillation technology. [0003] At present, most of the vacuum units used in this system are rotary vane pumps connected in series with Roots vacuum pumps. The advantage of this vacuum system is that it can pump the vacuum of the system to 0.1Pa. However, the disadvantage of this vacuum pump is that moisture or other volatile components Substances entering the vacuum pump oil w...
