Hexafluoroethane or trifluoromethane's purification device

The utility model discloses a hexafluoroethane or trifluoromethane's purification device, including an at least primary adsorption section of thick bamboo, every grade it is equipped with its inside heat to its outside cooling body of conduction to adsorb a section of thick bamboo. Accompany a large amount of heats of adsorption in the adsorption process, the heat of release will make the temperature in the section of thick bamboo rise, and high temperature can restrict absorption moreover, the absorption section of thick bamboo cooling of by freezing mechanism in to the adsorption process topromote the emergence of adsorption process. 本实用新型公开了种六氟乙烷或三氟甲烷的纯化装置，包括至少级吸附筒，每级所述吸附筒设有传导其内部热量至其外部的冷却机构。在吸附过程中伴随有大量的吸附热，释放的热量将使筒内的温度升高，而且高温会制约吸附，通过冷却机构对吸附过程中的吸附筒降温，从而促进吸附过程的发生。
