Falling Film Evaporator

Product Description

• Shell and Tube Design: The evaporator consists of a shell and tube layout, similar to other heat exchangers.
• Feed Introduction: The liquid feed to be concentrated enters at the top of the unit.
• Uniform Distribution: A distributor ensures the feed is spread evenly across the inside of the heating tubes.
• Thin Film Formation: As the liquid flows down the tubes, it creates a thin film on the tube walls due to gravity.
• Heat Transfer: A hot heating medium, typically steam, surrounds the tubes, providing heat to the liquid film.
• Partial Evaporation: As the film travels down and receives heat, a portion of the liquid evaporates.
• Co-current Flow: The remaining liquid and the vapor produced move down the tubes together in a co-current fashion.
• Separation: At the bottom of the evaporator, a separator section separates the concentrated liquid from the vapor.

• Efficient Heat Transfer: The thin film formed by the liquid allows for excellent heat transfer between the heating medium and the solution.
• Suitability for Heat-Sensitive Materials: Since the residence time of the liquid within the evaporator is low, it's ideal for concentrating heat-sensitive components.
• Reduced Operating Costs: The design allows for lower pumping power required compared to other evaporator types.
• Compact Footprint: Falling film evaporators are typically installed vertically, resulting in a smaller space requirement.

We are supplying the Falling Film Evaporator is an industrial device to concentrate solutions, especially with heat sensitive components. The evaporator is a special type of heat exchanger. It 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. The offered Falling Film Evaporator is suitable for evaporating and concentrating foaming materials. The offered evaporator is very effective and demanded in the various places.
