Description

technical field [0001] The invention relates to a distillation device, in particular to a distillation device for measuring volatile substances. Background technique [0002] Distillation is a thermodynamic separation process. It utilizes the different boiling points of the components in the mixed liquid or liquid-solid system to evaporate the low-boiling components and then condense them to separate the entire components. There are two types of evaporation and condensation. A union of unit operations. The current distillation device for volatile substances also utilizes the different boiling points of the components to evaporate and separate volatile substances with low boiling points, and then uses cooling water to condense the volatile substances separated by evaporation to obtain volatile substances. The current volatile substance distillation device only uses cooling water to condense the volatile substances separated by evaporation not only has low condensation and li...

AI Technical Summary

Problems solved by technology

The current volatile substance distillation device only uses cooling water to condense the volatile substances separated by evaporation not only has low condensation and liquefaction efficiency, but also has poor condensation and liquefaction effects, especially for volatile substances with low condensation temperatures. In other words, the effect of cooling water condensation and liquefaction alone is even worse
