Abstract

The invention discloses a solid fusion distilling technology especially a tellurium retort structure, which comprises the following steps: resolving the problems of small volume and low output; making the tellurium retort comprises distilling pot, copple and condenser; producing the distilling pot with rustless steel; choosing the diameter of distilling pot at 200-300mm, equipping column plate on the lower end of the condenser. This invention increases the output of single furnace and decreases the cost of production.

Description

technical field [0001] The invention relates to solid melting distillation technology, in particular to tellurium distillation furnace structure. Background technique [0002] Vacuum distillation is an important method for preparing high-purity tellurium, which is generally used in the production of 5N high-purity tellurium (99.999% tellurium content). The basic principle of this method is: heat 4N tellurium to the melting point, and the liquid tellurium volatilizes into tellurium vapor in a vacuum state, and the tellurium vapor rises and condenses when it is condensed. Different, condensed in different areas, so that impurity elements can be separated. [0003] The structure of the existing tellurium distillation equipment (distillation furnace) generally includes a distillation tank, a crucible and a condenser. The distillation tank is placed in the heating furnace, the crucible and the condenser are placed in the distillation tank, the lower end of the condenser is conn...
