近几年,气体爆炸导致的安全事故,对市民生命财产构成严重威胁,已引起政府、安监部门和社会公众的强烈关注和担忧,因此,对涉氨企业气体监测的研究引起了有关各方的广泛关注。广州和北京较早意识到了城市管网气体中潜在的危害,在国内率先开展了对城市管网内易燃易爆有毒有害气体监测的研究和应用。尽管这些监测措施在很大程度上不能完全避免涉氨企业泄露、爆炸事故的发生,但通过检测可燃气体的含量和运行状态,可采取正确 In recent years, the safety accidents caused by gas explosions have posed a serious threat to people’s life and property, which has aroused strong concerns and concerns from the government, safety supervision departments and the public at large. Therefore, the research on gas monitoring for ammonia-related enterprises has aroused the concern of all parties concerned The widespread concern. Guangzhou and Beijing were earlier aware of the potential hazards of urban pipe network gas and pioneered the research and application of monitoring flammable, explosive and poisonous gases in urban pipe networks. Although these monitoring measures can not completely avoid the leakage of ammonia-related enterprises, the explosion occurred, but by detecting the content of combustible gas and operating conditions, can take the correct
