基于PCS7的铜钴回收冗余控制系统设计

摘要

According to a new technology of copper and cobalt recovery was still in the manual operation, low degree of automation, design of copper and cobalt recovery redundancy control system based on Siemens PCS7 process control system to the entire production process automatic monitoring,for copper cobalt recovery thickener process of complicated mechanism, poor operating environment, has great inertia, nonlinear and material properties of wave analysis of frequent faults, design thickener structure, parametes self -turning fuzzy PID control. In Qinghai, mining group500000 tons of copper and cobalt recovery projects in the practical application proves that the control system can be very good to meet the control requirement, the comprehensive recovery efficiency improved, greatly reduce the labor intensity of the workers,the realization of safe and stable and reliable automated production.%针对新型铜钴回收工艺仍然处于人工手动操作、自动化程度低的问题,该文在西门子PCS7过程控制系统下设计铜钴回收冗余控制系统对整个生产流程进行自动化监控,针对铜钴回收浓密机工艺机理复杂,操作环境恶劣,具有大惯性、非线性以及来料性质波动频繁等缺点,分析浓密机的结构,设计浓密机的参数自整定模糊PID控制.通过在青海某矿业集团50万吨铜钴回收项目的实际应用证明,该系统能很好地满足控制要求.浓密机运行安全可靠,提高了综合回收效率,减轻了劳动强度,实现了安全稳定的自动化生产.
