SUBLIMATION APPARATUS FOR FINE PURIFICATION OF SUBSTANCES Russian patent published in 2014 - IPC B01D7/00 

FIELD: chemistry.

SUBSTANCE: sublimation apparatus for fine purification of substances has a heat-insulated heated cover, a heated housing, a sublimation chamber, a desublimation chamber divided into cells by parallel partition walls, arranged with spacing relative to the cover, a heat carrier chamber, a raw material inlet pipe, a process gas outlet pipe, heat carrier inlet and outlet pipes. The housing heater is made of self-contained blocks lying in each cell of the housing. The heat carrier chamber is made of sections, each lying in a cell. The heat carrier inlet pipes have a check valve. A self-contained block is a high-frequency generator.

EFFECT: providing a repeated sublimation-desublimation process without using manual labour, low power consumption, shorter time for maintenance of the sublimation apparatus and unit cost of the purified product, high specific output.
