摘　　要：焦化厂的含硫废料循环再生综合利用是钢铁生产企业迫在眉睫的一个重大资源化利用项目,废液除了含有大量的铁盐外,还含有相当数量可以回收及再生处理的酸溶液。在酒钢焦化厂引入废液制酸预处理工段的同时,设计了一套基于西门子AS 410 Smart冗余控制系统,有效地将原有的控制工艺和现有的废液制酸预处理系统进行互联互通,不仅实现了关键设备联锁控制,而且提高了系统的可靠性和稳定性。The comprehensive utilization of sulfur-containing waste recycling in coking plants is an urgent major resource utilization project for steel production enterprises.In addition to containing a large amount of iron salt,the waste liquid also contains a considerable amount of acid solution that can be recycled and regenerated.In this paper,while introducing the waste liquid sulphuric acid pretreatment section at the JISCO coking plant,a set of redundant control systems based on Siemens AS 410 Smart is designed to effectively combine the original control process and the existing waste sulphuric acid pretreatment system.Interconnection not only realizes the interlocking control of key equipment,but also improves the reliability and stability of the system.
