How does a falling film evaporator work
Did you know?
Due to the intimate contact of the liquid with the heating surface, these evaporators are sensitive to fouling from precipitating solids. Low liquid velocity at the inlet is usually not sufficient to perform an effective self-cleaning of the tubes. Falling film evaporators are therefore used in clean, non-precipitating liquids. … See more A falling film evaporator is an industrial device to concentrate solutions, especially with heat sensitive components. The evaporator is a special type of heat exchanger. See more In general evaporation takes place inside vertical tubes, but there are also applications where the process fluid evaporates on the … See more Horizontal falling film evaporators have a number of potential advantages over their vertical counterparts in the petrochemical industry, … See more • Falling Film Evaporators • Wolverine Tube Heat Transfer Databooks See more Falling film evaporators have a number of advantages over their flooded evaporator counterparts. They require a lower charge, as the entire shell (in the case of horizontal evaporators) or all the tubes (in the case of a vertical … See more • Climbing and falling film plate evaporator See more WebIn the falling film evaporators, the liquid and vapors flow in the downward direction parallelly. The concentrated liquid is then preheated until it starts boiling. An evenly thin film then enters the heating area with the help of a distribution apparatus in the evaporator.
