摘要
针对聚合釜间歇生产过程中存在设备多、参数多、控制复杂等特点,采用特定次序法技术解决了过程单元与整体生产自动衔接的问题。深入分析了多线加料与排队控制的生产要求,并通过WebField ECS-700 DCS组态软件平台编程实现了优化控制方案。工程实践验证了该控制技术能够有效提高助剂加料公用设备使用率。
In accordance with the features of batch production of polymerizer,e.g.,multiple equipment,multiple parameters and complicated control,etc.,by using the technology of specific sequencing method,the problem of auto-convergence of process unit and overall production has been solved.The productive requirements of multi-line feeding and queue control are analyzed,and optimal control strategy is implemented through WebField ECS-700 DCS corfiguration software platform programming.The engineering practice verifies that this control technology effectively increases the usage rate of common equipment for feeding additives.
