半干法烟气脱硫的自动控制系统

随着我国环境保护法规的不断完善和执法力度的加大，严格控制SO2排放，加快发展烟气的脱硫已迫在眉睫。文中简要介绍了一种半干法烟气脱硫工艺；阐述了工艺的PLC自动控制系统的组成及功能。其控制系统性能可靠，提高了脱硫系统的安全性和自动化程度。

Automatic Control System for Semi-dry Desulphurization of Flue Gas

As the environmental protection laws and the execution strength of the laws improve gradually in China, it is urgent for us to strictly control the emission of SO2 and better develop the desulphurization technology of flue gas. A kind of semi-dry flue gas desulphurization technique is briefly introduced and expatiated the formation and the function of the PLC automatic control system of this desulphurization technique. This automatic control system performs reliably and increases the security and automatization level of the desulphurization system.
