Evaporators - an overview | ScienceDirect Topics
Falling Film Evaporator Design Our falling film evaporator is the simplest and most commonly used type of film evaporator. The liquid flows as a thin film on the inside of heated vertical tubes, driv-en by gravity. The resulting vapor normally flows cocurrently with the liquid, in the centre of the tubes. A full evaporation stage consists of the Falling Film Evaporators are used for concentrating solutions along with heat sensitive components. The fluid content enters the head of the evaporator and is evenly distributed in heating tubes. The thin film flows downwards in the heating tube to the boiling temperature and is evaporated partially.

In falling-film evaporators, the feed liquor is introduced at the top tube sheet, and flows down the tubewall as a thin film. Since the film is moving in the direction of gravity rather than against it, a thinner and faster-moving film results, yielding higher heat-transfer coefficients and reduced contact times.

Falling Film/Forced Circulation 14" diameter x 180" long, 304 stainless steel shell side, 316 stainless steel tube side, type BEM Heat Exchanger with interchangeable channels (can be used horizontally or vertically), 2" O.D. tubing size, 94 sq.ft (8.75 sq.m) heat transfer area. There are mainly two frequently-used types: raising film evaporator and falling film evaporator. The falling film evaporator: the feed liquid distributes in the heat exchange tube as a film after it passes through the distributor. The liquid film will be heated by the steam at the outside of the tube when it flows down because of the gravity.

obtain a complete falling film inside a tube. Many tasks were performed to assess the performance of the liquid distribution systems. The minimum wetting rates of three different milks were found in a model evaporator tube under isothermal, heat transfer and evaporation conditions at 60ºC. A climbing/falling film plate evaporator is a specialized type of evaporator in which a thin film of liquid is passed over a rising and falling plate to allow the evaporation process to occur. It is an extension of the falling film evaporator, and has application in any field where the liquid to be evaporated cannot withstand extended exposure to high temperatures, such as the concentration of ...
