Multiple effect evaporator

Multiple effect evaporator is developed from the most primitive evaporation tank to single effect,double effect,triple effect,
quadruple effect or more effect,the purpose of which is to gradually reduce energy consumption.
The principle of multiple effect evaporator is to utilize the secondary vapor generated by the previous effect to heat the next effect to achieve the goal of energy saving.
Part of secondary vapor can be recovered by multiple effect evaporator ,and the more effect the more secondary vapor can be recovered ,this is different from MVR evaporator to
recover all secondary vapor.
Energy consumption per tonne of evaporated water:
MVC: ~ 15 kW.h / hr electric
Single effect: ~1.2 tons steam

Double effect: ~0.6-0.7 tons steam

Triple effect: ~0.37-0.46 tons steam

Quadruple effect: ~0.3-0.35 tons steam

Quintuple effect: ~0.24-0.3 tons steam

When designing the multiple effect evaporation system,we always take condensate recycling and secondary vapor heat into consideration to achieve the goal of energy saving
