Description

Technical Field

[0001] The utility model relates to the field of evaporation equipment, in particular to a low-energy-consumption double-effect falling film evaporator. Background Art

[0002] Falling film evaporation involves adding liquid from the upper tube box of the falling film evaporator's heating chamber. Liquid is evenly distributed to each heat exchange tube through a liquid distribution and film-forming device. Under the influence of gravity, vacuum induction, and airflow, the liquid flows from top to bottom in a uniform film. During the flow process, the liquid is heated and vaporized by the shell-side heating medium. The generated steam and liquid enter the separation chamber of the evaporator together. After sufficient separation, the steam enters the condenser for condensation or enters the next-effect evaporator as a heating medium, thus achieving multi-effect operation. The liquid phase is discharged from the separation chamber. The double-effect falling film evaporator is a type of falling film evaporator that features low energy consumption, stable operating performance, and a wide range of applications, playing an important role in modern industrial production.
