焦炉脱硫脱硝系统安全连锁设计的应用

Application of Safety Interlock Design for Desulfurization and Denitration Systems

对焦炉烟道气脱硫脱硝净化工艺进行简述,介绍了脱硫脱硝系统运行过程中存在的安全隐患。在设计过程中,脱硫脱硝装置与焦炉中控室等设备必须建立通讯并设置安全可靠的连锁控制。详细说明了增压风机在故障停机的状态下与焦炉相关重要设备的连锁。

This article briefly describes the desulfurization and denitrification purification process of coke oven flue gas,and introduces the safety hazards that exist during the operation of the desulfurization and denitrification system.During the design process,communication and safe and reliable interlocking control must be established between the desulfurization and denitrification device and the central control room of the coke oven.Detailed explanation was provided on the interlocking between the booster fan and important equipment related to the coke oven in the event of a fault shutdown.
