Description

Technical Field

[0001] The utility model belongs to the technical field of distillation towers, in particular to a high-efficiency filled distillation tower. Background Art

[0002] Chlorotrifluoroethylene, also known as chlorotrifluoroethylene, can form an explosive mixture when mixed with air. It can cause combustion and explosion when exposed to open flames or high heat. Chlorotrifluoroethylene decomposes at temperatures of 350-500°C to form a mixture of 3,4-dichlorohexafluoro-1-butene and 1,2-dichlorohexafluorocyclobutane.

[0003] A distillation tower is a tower-type gas-liquid contact device for distillation. The existing distillation tower has low mass and heat transfer efficiency during the distillation of trifluorochloroethylene. The heating rate of the material inside the tower kettle is slow, which easily causes uneven heating of the material. In the process of separating 3,4-dichlorohexafluoro-1-butene and 1,2-dichlorohexafluorocyclobutane, it is easy to cause incomplete separation. Utility Model Content
