摘　　要：常规湿法脱硫控制系统智能化程度低,需要现场工作人员定期巡检,出脱硫塔SO2排放量超标时有发生。新开发的湿法脱硫智能化控制系统节省了人力资源,使脱硫系统运行更高效,生产的脱硫石膏品质稳定,可根据脱硫塔入口SO2浓度智能化控制循环泵开启台数。该系统现已成功应用于多套水泥工业石灰石-石膏湿法烟气脱硫系统。The conventional FGD control system is less intelligent and needs regular inspection by workers on site,the SO2 emission from the desulfurization tower often exceeds the standard.The newly developed FGD intelligent control system not only saves human resources,but also makes desulfurization system run more efficiently.The quality of FGD gypsum is stable.The system can intelligently control the number of circulating pumps opening according to the SO2 concentration at the inlet of desulfurization tower.The system has been successfully applied to several limestone-gypsum wet FGD systems in cement industry.
