摘　　要：对一起化工企业废气处理系统安全事故进行了分析,提出了化工企业废气系统应关注的安全预防措施。得出的结论:化工企业废气系统的安全风险主要为有机废气组分浓度过高,若系统设计时除静电措施不到位,极易发生安全风险。同时,应在废气出口安装LEL检测装置和自动联锁切断系统,确保事故状态下高浓度废气不进入废气处理系统。This paper analyzes a safety accident of waste gas treatment system in chemical enterprise,and puts forward the safety preventive measures that should be paid attention to the waste gas system of chemical enterprise.Conclusion:the main safety risk of waste gas system in chemical enterprises is that the concentration of organic waste gas components is too high.If the electrostatic removal measures are not in place in the system design,it is very easy to have safety risks.Meanwhile,LEL detection device and automatic interlocking cut-off system shall be installed at the exhaust gas outlet to ensure that high concentration exhaust gas does not enter the exhaust gas treatment system under accident conditions.
