Heat circulation type quick solution distillation and condensation device

Abstract

The invention discloses a heat circulation type quick solution distillation and condensation device which comprises a base. A distillation drum is fixedly arranged at the top of the base through a supporting frame, a heating pipe is fixedly arranged at the inner bottom of the distillation drum through supports, a spiral pipe is fixedly arranged in the distillation drum, and the bottom end of the spiral pipe penetrates the side wall of the distillation drum to the outside of the distillation drum. A pressure cylinder is arranged at the bottom of a supporting plate which is fixedly arranged at the top of the distillation drum through supports, a ventilation pipe is connected to the lower right corner of the pressure cylinder, the bottom end of the ventilation pipe penetrates the top wall ofthe distillation drum to be connected with the top end of the spiral pipe, and an air inlet pipe is connected to the ventilation pipe and positioned in the distillation drum. A piston is slidably arranged in the pressure cylinder, and a piston rod is fixedly connected to the left end face of the piston. By extraction of air in the distillation drum through the pressure cylinder, the internal air pressure of the distillation drum is reduced, a solution boiling point is lowered, and distillation efficiency is improved. In a distillation process, the pressure cylinder enables steam to internallypass through the spiral pipe to realize heat cyclic utilization.

Description

technical field [0001] The invention relates to the technical field of chemical machinery, in particular to a thermal circulation type solution rapid distillation and condensation device. 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. Compared with other separation methods, such as extraction, filtration and crystallization, its advantage is that it does not need to use other solvents other than the system components, so as to ensure that no new impurities will be introduced. [0003] Ordinary distillation equipment often only distills the solution by heating to make the solution boil, which has problems such as slow distillation speed and low heat utilization rat...

Problems solved by technology

[0003] Ordinary distillation equipment often only distills the solution by heating to make the solution boil, which has problems such as slow distillation speed and low heat utilization rate, and the condensation speed after distillation is also slow, resulting in a slow overall distillation speed of the solution, which is not conducive to chemical production
