Falling film evaporation is to add the feed liquid from the upper tube box of the heating chamber of the falling film evaporator, and distribute it evenly into each heat exchange tube through the liquid distribution and film forming device. Under the influence of gravity and vacuum induction and air flow, it forms a uniform film. Flow up and down.

Falling Film Evaporator. Evaporation is the unit operation of concentrated solution. Usually, the solvent is volatile, while the vapor pressure of most solutes approaches zero and cannot be volatile. The process by which a solution is concentrated by removing part of the solvent by vaporization under boiling conditions is called evaporation.

Falling film evaporators are vertical shell and tube heat exchangers. Typical TEMA types are BEM, NEN or a combination of the two. The major difference between a typical shell and tube heat exchanger and a falling film evaporator is the liquid distribution at the top of the unit. Liquid entering the top of the unit passes either through a spray ...

Falling film evaporators can be used in conjunction with blow heat recovery at mills using batch digesters because lower temperature gradients are required. The steam discharged during blowing is used to heat large quantities of water. The hot water is then used in liquor evaporation until the next digester blow reheats it.

In falling film Evaporator Liquid evenly distributed over top tube sheet using uniquely design distributor tube inserts. Liquid flows under gravitational force as a thin film on the inside of vertical tubes which is heated by steam from outside resulting vapour normally flows co-currently with the liquid in the center of the tubes.
More details
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 evaporation to occur …

In falling film evaporators, the liquid product usually enters the evaporator at the head of the evaporator. The liquid enters the heating tube and forms a thin film on the tube wall where it flows downwards at boiling temperature and is partially evaporated. In most cases, steam is used for heating the evaporator.
