摘要
介绍了HOLLIAS_MACS系统在某钢铁厂烟气脱硫控制系统中的应用,阐述了干法脱硫系统的工艺流程、控制流程、控制系统硬件组态和软件设计。针对烟气中含硫浓度、烟气流量等不确定性的特点,控制系统采用前馈-反馈的控制算法,根据进入吸附塔的烟气流量进而控制辊式给料机的下料速度,取得了很好的脱硫效果。自系统投运以来,运行顺畅,过程数据控制精确,脱硫效率显著。
The application of HOLLIAS_MACS system in the control system of flue gas desulfurization for a certain iron and steel plant is introduced.The technique process and control process of dry desulfurization system,hardware configuration and software design of control system are described.According to the characteristics of sulfur concentration,flue gas flow and uncertainty in flue gas,the feedforward-feedback control algorithm is adopted in the control system.The feeding speed of the roll feeder is controlled according to the gas flow accessed into the adsorption tower,and a good desulphurization effect is obtained.After the application of the system,the system has the advantages of smooth operation,accurate process data control,and significant desulfurization efficiency.
