Review on Falling-film Evaporator

Features:

1) Feeding solution of falling-film evaporator is added from the top of the evaporator, and in the distribution of gravity fall into a film along the wall, and in this process the evaporation enriched at its bottom to obtain a concentrated solution.
2) Since the solution was made to flow in one way a film type evaporator, the heat transfer coefficient is higher.
3) The residence time is short, difficult to cause material deterioration.
4) The amount of liquid retention is small, falling film evaporator can be supplied based on needs of energy, vacuum change, feeding quantity and concentration rather take a quick operation.
5) Since the process fluid flow under gravity only, rather than temperature differential to drive, it can be used low temperature evaporation.
