摘要
双碱法脱硫是目前世界上应用最多的烟气脱硫工艺。本设计以双碱法脱硫理论为基础,采用西门子S7-300PLC为控制核心,上位机通过MPI通信协议与PLC通信并重点对脱硫塔PH值,碱罐液位,循环泵压力,进水口流量等现场信号进行集散在线监测与控制。
Dual Alkali FGD is the most widely used in the world for flue gas desulphurization technology. The design is based on the theory of dual Alkali FGD, adopts Siemens S7-300 PLC as the control core. PC communicate with PLC is through the MPI communication protocol. It focus on the desulfurization tower pH, alkali tank liquid level, pressure of circulation pump, inlet flow field signals and are distributed online monitoring and control.
