Falling film evaporator

Falling film evaporator: Product overview and features: Falling film evaporator is a high-efficiency single-pass non-circulating film evaporation equipment. Its film evaporation principle determines that it has high heat transfer efficiency, small temperature difference loss, short material heating time, It is not easy to deteriorate, easy to operate with multiple effects, low energy consumption, and small equipment size. It is especially suitable for heat-sensitive materials and materials with low concentration that are not easy to crystallize.
Working principle: Falling film evaporation is to add the material liquid from the upper tube box of the heating chamber of the falling film evaporator, and evenly distribute it into each heat exchange tube through the liquid distribution and film forming device. Under the action of gravity, vacuum induction and air flow, down, flowing from top to bottom into a uniform film shape. During the flow process, it is heated and vaporized by the shell-side heating medium, and the generated steam and liquid phase enter the separation chamber of the evaporator together. After the vapor and liquid are fully separated, the steam enters the condenser for condensation (single-effect operation) or enters the next-effect evaporator as The medium is heated, thereby achieving multi-effect operation, and the liquid phase is discharged from the separation chamber.
