Description

Technical Field

[0001] The utility model relates to the field of flash evaporation, in particular to a reduced pressure flash evaporation crystallization kettle. 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, these saturated liquids become saturated vapor and saturated liquid under a portion of the container pressure. Evaporative crystallization is a process of evaporation. As the solvent evaporates, the original unsaturated solution gradually becomes a saturated solution, and the saturated solution gradually becomes a supersaturated solution. At this time, the solute begins to precipitate from the supersaturated solution. Many solutes can precipitate in the form of crystals (some can precipitate in a non-crystalline form). This is the crystallization process.

[0003] When flash crystallization is performed on some substances, the substances inside the flash tank will quickly vaporize, liquefy or crystallize. During this process, the hot gas will float upwards. The floating gas will easily contaminate the top of the flash tank, which is difficult to clean over a long period of time. At the same time, the flashed liquid or slurry inside is relatively viscous and difficult to mix and discharge.
