Problems solved by technology

[0002] At present, when solid products are distilled in high vacuum, water jet-Roots vacuum unit or rotary vane vacuum pump is used to provide a vacuum of no more than 100Pa for high vacuum distillation. However, in this low-pressure environment, some products are easy to sublimate, enter the vacuum unit, and condense Adhering to the rotor or vane, hindering the operation of the machine, or even clogging and damaging the pump body, and part of it is discharged with the gas, polluting the environment

Abstract

The invention discloses a cooling device in a high-vacuum distillation system. The cooling device consists of a casing, an air outlet, an air inlet and a discharging port. The casing is a double-layer hollow casing, the lower portion of the hollow casing is provided with a water inlet, the upper portion of the hollow casing is provided with a water outlet, the water inlet and the water outlet are communicated with a middle cavity of the hollow casing, and the upper portion in the casing is provided with an air blocking plate. The cooling device has the advantages of being simple in structure, recovering products and protecting vacuum devices through shock cooling.

Description

technical field [0001] The invention belongs to the technical field of chemical equipment, and in particular relates to a cooling device in a high vacuum distillation system. Background technique [0002] At present, when solid products are distilled in high vacuum, water jet-Roots vacuum unit or rotary vane vacuum pump is used to provide a vacuum of no more than 100Pa for high vacuum distillation. However, in this low-pressure environment, some products are easy to sublimate, enter the vacuum unit, and condense Adhering to the rotor or rotating vane, it hinders the operation of the machine, or even blocks and damages the pump body, and part of it is discharged with the gas, polluting the environment. Contents of the invention [0003] The purpose of the present invention is to improve the deficiencies of the prior art and provide a cooling device in a high-vacuum distillation system that has a simple structure, recovers products through quenching, and protects vacuum equi...
