摘要
本项目利用西门子S7-300系列PLC完成了对原有换热系统的改造。原有换热系统通过手动设定PID表的温度设定值来达到对换热阀门开度大小的控制,改造后换热系统由半自动控制系统转换为全自动控制系统,并最大限度的利用了回收的凝结水的热量。
This project completed the renovation of the original heat exchange system by using the Siemens S7-300 series PLC.The original heat exchange system control the heat exchange valve opening degree by setting the PID table temperature manually.After the renovation,the heat exchange system from the semi-automatic control system to a fully automatic control system,and take maximum advantage of the heat of the recovered condensate.
