Oct 09, 2019 · How Falling Film Works. A falling film evaporator (FFE) is a specific type of vertically oriented shell and tube (S&T) heat exchanger that is used to separate two or more substances with different boiling point temperatures. A shell and tube heat exchanger is divided into two compartments.

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.

In falling film evaporators, liquid enters the top of the unit and forms a continuous film that flows down the inside of heating tubes via gravitational force. The liquid film flows downward through the tubes at boiling point. The liquid partially evaporates, concentrating the liquid. Falling film evaporators are ideal for heat-sensitive liquids because they allow …

In falling film devices, this process happens at the liquid-vapor interface. It means that the device can use a lower temperature, meaning less energy use and some other benefits. For example, as there is no nucleate boiling on the tube walls, the solution in the evaporator will not crystalize. These long-tube devices are very energy efficient ...

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

• Waste heat usage – the evaporator can be heated by exhaust gas streams or hot water due to the flexible design of the heating side. • Simple process control and automation – due to their small liquid content falling film evaporators react quickly to changes in energy supply, vacuum, feed quantities, concentrations, etc.

Working principle. For the thermal separation of a mixture a thin film is produced at the heated wall of a cylindrical or conical evaporator. A distribution ring on the rotor distributes the liquid evenly across the periphery. Then, the blades fitted at the rotor spread the liquid as a thin film of min. 0.5 mm over the heat transfer surface.
