《水泥》2013年8期介绍了辽源渭津金刚水泥有限公司2×5 000t/d生产线SNCR烟气脱硝工艺系统情况[1],本文则重点介绍该项目的控制系统。1脱硝控制系统脱硝系统使用西门子300PLC系统来控制,与熟料生产线DCS系统(ABB 800F系统)不进行通讯,只从原生产线系统采取部分与生产相关的信号进入到脱硝系统。工艺控制示意见图1。2硬件设计设一套PLC(CPU位于1号窑尾控制室,在2号窑尾控制室设置远程IO站)及上位机控制系统(操作站)。操作员通过计算机画面可同时监视和控制脱硝装置的运行。
This paper introduces the control system of SNCR flue gas denitrification system of 2 × 5000t / d production line of Liaoyuan Weijin Jingang Cement Co., Ltd. [1]. 1 Denitration Control System The denitrification system is controlled by Siemens 300PLC system and does not communicate with the DCS system (ABB 800F system) of the clinker production line. Only part of the production-related signals are taken from the original production line system into the denitration system. Process control schematic shown in Figure 1.2 Hardware Design Set a PLC (CPU is located in the No. 1 kiln tail control room, No. 2 kiln tail control room set up a remote IO station) and the host computer control system (operator station). The operator can simultaneously monitor and control the operation of the denitrator through the computer screen.
