摘　　要：伴随世人对环保意识的提高,解决SO2的污染已迫在眉睫。燃煤锅炉烟气干式脱硫比较适合我国国情。文章详细分析了干式脱硫工艺过程,设计了基于PLC的脱硫控制系统,并采用复合控制算法,通过试用达到了良好的控制性能。It is urgent to solve the pollution of SO2 along with the people's consciousness of environmental protection. The dry dust desulphuration of coal boiler is regarded as being more suitable to the situation of China.This paper analyzes the dry desulphuration process in detail and describes the PLC-based desulpuration control system design in which the complex control arithmetic method is adopted. The control performance is proved valuable in practice.
