摘　　要：分析了转炉煤气自动化回收系统和控制要求,认为煤气回收必须以CO和O2含量为基础条件,来确定回收时机。从西林钢铁集团有限责任公司转炉应用角度讨论了基于PLC的全自动煤气回收系统,介绍了系统构成,详述了烟气净化、成分分析、罩口微差压自动调节、风机高低速自动调节、回收放散无扰切换等控制功能。实践证明,该自动控制系统的使用,实现了转炉煤气资源再生,保证煤气质量、减少煤气燃放、确保安全运行,达到环境保护与能源综合利用的要求。The converter gas automatic recovery system and its control requirements are analyzed.It＇s recognized that the recovery time should be determined on the basis of CO and O2 concentration containing in the gas in the process of recovering the converter gas.In view of application of converter gas in Xilin Iron Steel Co.,Ltd.,the PLC based full automation gas recovery system is discussed,the structure of the system introduced and a few functions such as fume purification,chemical compositions analysis,self regulation of the differential pressure at the hood mouth,self-regulation of high and low velocity of blower and interference free switchover of recovery and emission expatiated.Practical results demonstrate that by application of the automation control system reclamation of the resource of converter gas is realized,gas quality ensured,combustion and emission of gas reduced and running safely guaranteed.In the end the requirements of combination of environment protection with comprehensive utilization of energy resource are satisfied.
