Falling film evaporation on the horizontal tube is a new technology for seawater desalination. Because the phase changes occur on both sides of film evaporation and the film flow of the liquid outside the tube contributes to speed up the separation of vapor and liquid, its heat transfer coefficient is high.

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 Evaporator Design. Shell tube evaporators, on the other hand, do not use a wiper blade to obtain a thin film. A falling film evaporator is comprised of a bundle of parallel tubes that are welded together at each end. The tube bundle is encased in a jacket that allows heat transfer fluid to be pumped across the outside of the tubes.

Falling film evaporators are generally used when the potential for tube coating is minimal, whereas forced circulation flash evaporators are preferred when tube coating may be a significant problem. Evaporator construction details are as important as selecting proper type of evaporator. In rendering applications the recommended material

Falling-film evaporators from BMA used in cane sugar factories have a higher juice distributor dome, making them easier to inspect and clean. Whenever necessary, the juice distributor and heating tubes can be cleaned with a high-pressure water jet from the top tube plate, without opening the flange.

In falling film evaporators (Wiegand, 1971) the feed is introduced at the upper end of long vertical tubes, taking care to distribute the liquid as a film over the entire internal surface of the tubes (Fig. 9.10). The film moves downward by gravity, assisted by vapor drag.

In the first stage, process liquid enters the falling film evaporator through the inlet feed pipe and is directed to the top liquid distributor. The distributor then delivers the liquid to the tube sheet. It is itself equipped with many drip points to ensure the generation of an even and calm static liquid height outside the tubes.

Jul 23, 2019 Constructions of a Falling Film Evaporator. The falling film evaporator system mainly consists of several parts. The first part is the evaporator (the heat exchanger), which is used to heat and evaporate liquid materials. The second part is the separator, mainly used to separate the concentrated liquid and the secondary steam generated after ...

The falling film evaporator is a crucial equipment of the plant as it is highly useful for reducing the steam consumption. No extra energy is required to pass the juice through FFE, as the juice fed from the top descends over the heating surface in a thin film. Shrijee manufactures falling film evaporator ranging in heating surface from 1500m 2 ...
