Falling Film Quadruple effect Evaporator

Multi-effect falling film evaporation system

Basic technology

The feeding liquid will flow into the tubular falling film evaporator from the upper part of the heater, the feeding liquid flows down along the heater surface by the liquid distributor, By gravity and airflow effect, the feeding liquid flows from top to bottom, and be evaporated. After then the vapor-phase and liquid-phase flow into separator together, The separator will separate the vapor and liquid totally, consequently bring about the secondary vapor and concentrated liquid.

For increasing the concentration of the discharging liquid, even avoiding fouling drywall condition, forced circulation falling film evaporator applied in such situation. That's saying to equip forced circulation pump to falling film evaporation system.
