Description
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: ~ *5 kW.h / hr electric
Single effect: ~1.2 tons steam
Double effect: ~0.**0.7 tons steam
Triple effect: ~0.***0.*6 tons steam
Quadruple effect: ~0.**0.*5 tons steam
Quintuple effect:~0.***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.
