专用DCS在小型工业锅炉湿法脱硫系统中的应用

Specific DCS Used in Wet FGD System for Small Industrial Boilers

本文简要介绍了一种新型的双碱双循环法的湿式烟气脱硫工艺及实施方案,并对其专用DCS自动控制系统的组成及功能进行了系统阐述。实践表明该系统自动化程度高,使用简易,脱硫效率稳定,有效地降低了系统运行的人工费用以及项目的维护费用,并且项目实施成本只比PLC型式略高。

This paper introduces a new type of technology and implementation plan for wet flue gas desulfurization based on dual alkali and double circulation technology,and it systematically expounds the composition and functions of specific DCS automatic control system.Practice shows that it has a high degree of automation,and easy to use,and its desulfurization efficiency and stability,effectively reducing the labor costs of system operation,and project maintenance costs,and project implementation costs are only slightly higher than the PLC type.
