摘　　要：为了防止火炬放空时发生回火,引发火灾、爆炸等事故,有必要对火炬放空系统阻火设施的设置进行研究。通过分析火炬放空过程中发生回火的工况,以及防止火炬回火和爆炸所采取的措施,调研了中国石油集团工程设计有限责任公司西南分公司设计的几个天然气处理厂及炼油厂的火炬放空系统阻火设施的设计、使用情况,对国内外相关标准中关于阻火设施的设置规定进行了分析对比。列举了国内阻火设施发生故障的案例。天然气处理厂火炬放空系统中阻火设施的设置是极其重要的。火炬头应选择带有吹扫气的阻火设施,放空系统设置阻火器需慎重。In order to prevent fire and explosion resulting from possible fire comeback in flare venting,it is necessary to research the setup of fire arresting device in flare system.Analyzed are working conditions leading to possible fire comeback in flare venting and measures taken for preventing fire comeback and explosion,researched are design and operation conditions of different fire arresting devices in flare systems of several gas treatment plants and oil refineries designed by China Petroleum Engineering Co.,Ltd.Southwest Company(CPE-SW)and contrastively analyzed are relative provisions in Chinese national standards and international standards on setup of fire arresting device in flare system.Analyzed are several examples of fire arresting device failures at home and abroad.Described is the importance of fire arresting device setup in gas treatment plant and it is pointed that fire arresting device with purge gas shall be selected for flare tip and more attention shall be paid to fire arresting device setup in flare system.
