摘　　要：以某10t矿热炉煤气净化回收系统升级为背景,介绍了煤气净化回收系统的组成和回收过程,应用PI控制方法和炉口微差压、回流阀开度双闭环的控制方式,实现了煤气回收净化过程中的炉膛压力、文氏管压差的自动控制,并增加了数据采集、保存、输出和异地通讯等系统功能,有效提高了煤气回收的效果,提升了企业的自动化管理水平。Taking the upgrade of the flue gas purification and recovery system in a 10 t ore smelting electric are furnace as an example, we introduce the recovery process. With the method of PI control, micro difference pressure, flowing vault double closed loop control, the automatic control of furnace pressure, ventrui tube pressure difference is realized during the flue gas purification process. Other system functions are added such as data acquisition, saving, output and remote communication. It enhances the effeciency of the flue gas recovery and promotes the automatic level of the management.
