摘要:料液进入蒸发器分为低于沸点、等于沸点或高于沸点三种,对于蒸发器尤其是降膜式蒸发器来说,低于沸点进料一般都需要将料液温度预热至沸点或沸点以上温度才能进入到蒸发器内进行蒸发。无论何种蒸发器低温进料蒸发与高温蒸发效果完全两样,本文就此进行阐述。

Abstract: The feed liquid into the evaporator can be divided into three types: below the boiling point,equal to theboiling point or above the boiling point. For the evaporator,especially the falling-film evaporator,feed below theboiling point generally needs to be preheated to the boiling point or above the boiling point temperature before entering the evaporator for evaporation. No matter what kind of evaporator low temperature feed evaporation and high temperature evaporation lead to completely different effect,which is elaborated in this paper.

Key words: evaporator;feed temperature;effect;compare
