Types of Evaporator

Agitated Thin Film Evaporators
Agitated Thin Film Evaporators

Agitated Thin Film Evaporators Thin film or wiped film evaporators are used to separate a mixture of liquids having different boiling points. It is also used to increase the concentration of liquids.

The evaporator works the opposite of the condenser, here refrigerant liquid is converted to gas, absorbing heat from the air in the compartment. When the liquid refrigerant reaches the evaporator its pressure has been reduced, dissipating its heat content and making it much cooler than the fan air flowing around it.

Climbing and Falling-Film Plate Evaporator
Climbing and Falling-Film Plate Evaporator

The climbing/falling film plate evaporator is specifically designed to produce a thin film during both the climbing and falling phases. For the climbing film evaporators, the feed is introduced at the bottom of the tubes.

Evaporative
Evaporative

An evaporative cooler (also swamp cooler, desert cooler and wet air cooler) is a device that cools air through the evaporation of water. Evaporative cooling differs from typical air conditioning systems, which use vapor-compression or absorption refrigeration cycles.

Falling Film Evaporator
Falling Film Evaporator

Falling film evaporators are therefore used in clean, non-precipitating liquids. A typical application, in chemical industry, is for concentration of caustic soda. Falling Film Evaporators versus flooded evaporators. Falling film evaporators have a number of advantages over their flooded evaporator counterparts.

Multiple-Effect Evaporators
Multiple-Effect Evaporators

A multiple-effect evaporator, as defined in chemical engineering, is an apparatus for efficiently using the heat from steam to evaporate water. In a multiple-effect evaporator, water is boiled in a sequence of vessels, each held at a lower pressure than the last.

Natural/Forced Circulation Evaporator
Natural/Forced Circulation Evaporator

Natural/forced circulation evaporators have many advantages, making them the more popular choice of evaporator in industry. The liquid entering the circulation evaporator will boil in the separator, not on a heating surface, hence minimising fouling, whereas with plate evaporators, boiling will occur on a heating surface.

Rising Film (Long Tube Vertical) Evaporator
Rising Film (Long Tube Vertical) Evaporator

A rising film or vertical long tube evaporator is a type of evaporator that is essentially a vertical shell and tube heat exchanger. The liquid being evaporated is fed from the bottom into long tubes and heated with steam condensing on the outside of the tube from the shell side.
