High Efficiency Evaporator Falling Film 

Falling film evaporation system application: Our 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. Working Principle: In falling film evaporators, the liquid product usually enters the evaporator at the head of the evaporator.tube wall where it flows downwards at boiling temperature and is partially evaporated. In most cases, steam is used for heating the evaporator. Its structure is roughly the same as film-lift evaporator, liquid is added from top. A liquid distribution device is installed at the top of each tube, so that the liquid can be uniformly received.The secondary steam and the concentrated liquid generally flow together, and the material liquid flows along the pipe wall in a film form due to the action of the secondary steam. External heating evaporator belongs to New circulation external heati…
