我司一双效蒸发器处理醇水，对末效出料温度控制有要求，近日出现末效温度降低，上升困难，求教各位海友末效出料温度都有哪些影响因素？

Reply #22020-12-24

主要是分离醇水和其它物质，一效温度大约为90-95，真空-0.04，二效出料温度75，真空-0.075，醇水蒸气为二效热源，回收另一种物质；目前就是二效出料温度较低，上升困难；应该是进料组成该发生变化，不知道哪一组份突然变高或者变少

二次蒸汽应设计不凝气排出口，不凝气造成换热效果差！

不凝结气体是指空气么，在负压条件下影响应该不会这么大？求齐前辈指导

把进料原料和一效出料组分分析一下，应该是组分发生变化了

需要检查一效蒸汽喷嘴是否故障，导致压力不平衡，一效二效压差增大，导致一效温度高、二效温度低，另外通过调节二效真空度便可控制温度，

应该是物料组成发生变化，运行几天后恢复正常了

进料组成改变，应该是醇少了吧

这个我们将醇含量提升后没有什么效果

哦，那就不清楚了，按照你这个温度来说，分离的是乙醇水么？
