基于PLC的循环气压缩机安全联锁设计
|
摘要
以环氧乙烷生产工艺中循环气压缩机为例,介绍了循环气压缩机在反应单元中的联锁控制。为确保压缩机安全稳定地运行,设计了一套基于PLC的双重化冗余压缩机紧急停车系统。同时利用软件PLCSIM对系统进行了仿真模拟,通过Win CC软件设计了人机界面,实现了工艺参数的实时监测。此外系统采用的数据通过多原则表决与修正,避免了由于信号误差带来的经济损失,为工业安全起到一定的保障作用。
This paper introduces the interlock control of recycle compressor in reaction unit,which based on the recycle compressor in ethylene oxide production process as an example. In order to ensure the safe and steady operation of the compressor,Emergency emergency shutdown system of recycle compressor was designed based on the dual redundant PLC. Meanwhile,simulation test is performed by software PLCSIM to interlocking system. The man-machine interface of monitoring was designed by Win CC configuration software and realize real-time monitoring for process parameters. In addition,these data input of the system through multiple principles voting and correction to avoid the economic loss caused by the error signals,which play a security role for industrial safety.
