前言酸浴系统是为粘胶人造丝生产提供合格凝固浴的“肝脏”部门,而多效蒸发则是整个酸浴系统的“心脏”工段。它不仅要完成酸浴的浓缩,还要完成酸浴在系统内部的调配。衡量闪蒸效果好坏的最重要指标就是蒸发量大小。本文着重就影响蒸发量的各变量进行理论探索,并在理论上解答实践中碰到的问题。 Introduction The Acid Bath System is the “Liver” department that provides a qualified coagulation bath for the production of viscose rayon, while the Multi-Effect Evaporation is the “Heart” section of the entire acid bath system. It not only to complete the acid bath concentration, but also to complete the deployment of acid bath in the system. The most important indicator of the effectiveness of flash evaporation is the amount of evaporation. This article focuses on the theoretical analysis of the variables that affect the evaporation, and in theory to answer practical problems encountered.
