摘要
介绍了腈纶生产中溶剂回收的多效蒸发工艺的特性，认为五效蒸发是最佳选择。详细说明了五效蒸发设备的清洗及节能措施。还介绍了世界上先进的自清洗系统和进一步强化溶剂回收与环境保护的方法。
The behaviour of multiple\|efficiency evaporation was introduced. The cleaning and energy saving unit of the equipments of five\|efficiency evaporation that proved to be the best for NaSCN recovery were described in details. The advanced self\|cleaning system, as well as the technology of further intensifying recovery of the solvent and evironmentally friendly processes, was introduced.
