Heating equipment and its application: distillation purification apparatus and distillation purification method

Abstract

A heating device and its application in distillation purification apparatus and method are disclosed. The heating device includes: a heating tank having a heating space and a tank opening, and connected to a heater; a bag having a receiving space and a bag opening, placed in the heating space of the heating tank; the bag opening of the bag is positioned inside the tank opening of the heating tank; the receiving space of the bag contains a raw liquid; the heater heats the raw liquid, causing the target substance in the raw liquid to evaporate and generate target substance vapor; thereby, this structure can effectively isolate other metal ions to generate high-purity target substance vapor.

Claims
