反应精馏装置温度上升过程

主要测温点为5个,均为探头式热电偶。 1、冷凝器进口温度 2、冷凝器出口温度 3、塔顶温度 4、塔顶回流处温度(这个地方我不太清楚,应为探头插入比较浅,应该是回流液)

主要测温点为5个,均为探头式热电偶。

1、冷凝器进口温度

2、冷凝器出口温度

3、塔顶温度

4、塔顶回流处温度(这个地方我不太清楚,应为探头插入比较浅,应该是回流液)

5、塔釜温度(在反应器顶部)

这几个温度,源于一个例子 水和乙醇的分离:进料就不说了,打到反应器中(就是塔釜),然后加热。1、2温度基本变化不大从-1~2度左右吧,后来也就5~6度左右;

2相应从1~3度到后来7~10度.这个没什么好讲的。

3的温度在塔釜温度上升后稳定在78~80度左右。

5就是一直升高了靠着加热蒸汽到100多度。重点就是4的,开始加热时上升很慢,基本不动,然后在塔顶正常上升时有所起色,一直缓慢上升。
