阻火器性能测试方法试验性研究

A pilot study of flame arrester performance test methods

在现代工业生产过程中,可燃气体的爆炸事故频繁发生,造成大量的人员伤亡和严重的财产损失,因此对于管道内可燃气体燃烧爆炸的抑制研究已逐渐成为安全技术领域的一项重要课题。阻火器是一种用来阻止易燃气体和易燃液体蒸气火焰蔓延的安全装置,近年来已被广泛应用在石油化工、天然气等工业领域。阻火器通常安装在装置的进出口或者管道上,其中的核心部件阻火单元允许介质流通,阻灭火焰。随着现代社会的发展,人们对于安全问题越来越重视,因此,对于阻火器的性能测试就显得必不可少。由于阻火器的相关检测技术在我国开展得较晚,相对国外标准而言,国内标准不仅技术滞后、更新周期长而且体系不完善不配套。因此本文对阻火器性能测试方法进行了研究,以提高我国在这一领域的检测水平,推动国内对阻火器性能完整检测现有技术的完善,同时对保障安全生产和人民的生命安全也具有重要的现实意义。

The combustible gas explosions occurred frequently in modern industry,and these hazards have resulted in a great amount of casualties and property losses.So the research of combustion and explosion of combustible gas in pipeline has become an important subject in the fields of safe technology.Flame arrester is a kind of safety equipment which can prevent flammable gas and liquid vapors from spreading,and widely used in petrochemical and natural gas industry in recently years.As a class of safety equipment, flame arrester is installed in the import and export of the device or pipe.Element which is the core components of flame arrester allows media circulation and block off the flame.With the development of modem society,people pay much attention on safe production.Accordingly,the performance test on flame arresters used for safe production seems to be necessary.The research of the flame arrester related detection technology started very later in China,and relative to the foreign standards,domestic standards technology is backward in technology,shorter period of refresh technology,incomplete standard system. So in this paper the study of flame arrester performance test method is carried out,in order to improve the detection level in this field,and promote the existing technology that complete performance detection of flame arrester.At the same time,it will be benefit for both of explosion prevention and the security of production and people.
