Description

Technical Field

[0001] The utility model relates to the technical field of flash evaporation, in particular to a 3,4,5-trichlorotoluene trifluoride flash evaporation device. Background Art

[0002] Flash evaporation is the phenomenon that when a high-pressure saturated liquid enters a relatively low-pressure container, due to the sudden drop in pressure, the saturated liquid becomes a part of the saturated vapor and saturated liquid under the container pressure. The fluid temperature is higher than the boiling point under the pressure, and the fluid boils and vaporizes rapidly in the flash tank, and the two phases are separated. The existing 3,4,5-trichlorotrifluorotoluene flash evaporation device is generally only equipped with one exhaust port during use. When the gas pressure inside the flash tank is too high, the exhaust effect is slow. Therefore, we have launched a new 3,4,5-trichlorotrifluorotoluene flash evaporation device. Utility Model Content
