本文就如何进行多效蒸发器设计,通过四个适当的假设,论证推导了计算多效蒸发器的有关公式,从而直接方便地计算确定蒸发器的热交换面积和其它重要变量。 (一) 计算公式的论证推导设计多效蒸发器时,由于存在某些复杂情况,往往需通过反复计算。如果我们对下列问题作出假设:沸点进料;各效传热面相 In this paper, how to carry out multi-effect evaporator design, and through four appropriate assumptions, the relevant formula for calculating multi-effect evaporator is deduced, which can directly and conveniently calculate and determine the heat exchange area and other important variables. (A) Calculation formula of the argument Derivation of multi-effect evaporator, due to the existence of some complex situations, often through repeated calculations. If we make the assumptions on the following questions: Boiling point feed; effective heat transfer surface
