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 article briefly introduces a new double alkali double cycle wet flue gas desulfurization process and implementation of the program, and its dedicated DCS automatic control system components and functions were systematically described. Practice shows that this system has high degree of automation, easy to use, stable desulfurization efficiency, effectively reducing the labor cost of the system operation and project maintenance costs, and the project implementation cost is only slightly higher than the PLC type.
