摘要  2013年11月22日发生的黄岛管道爆炸事故共造成62人死亡,136人受伤。调查显示,在排水管道内部存在多处混凝土栅栏障碍物,油气在排水管道内聚集爆炸产生的超压和物体碎片是造成伤害的主要原因。为了定量探究障碍物对管道内油气燃爆破坏效应的影响,本文搭建了长3 m、内径100 mm的油气管道燃爆测试装置,在管道后半段可根据需要安置各类障碍物。在常温常压下以丙烷与空气的混合气为燃爆介质,采用弱点火方式进行了燃爆试验,研究了在不同障碍物阻塞率、数量和间距条件下管道内部的超压分布和变化。

Abstract

  On November 22th 2013, in Qingdao, the Huangdao, pipeline exploded. In this accident 62 people died and 136 people were injured. The survey shows that the drainage pipe explosion overpressure and object debris were the main reasons for the huge damage. There are many concrete fence obstacles in the pipelines that may increase the explosion overpressure. In order to study the effect of obstacles on pipeline explosion, a 3m-long, 100mm-diameter device was built for oil and gas pipelines explosion tests. The device consists of 2 short pipelines and all kinds of obstacles can be installed in the second one. In the experiments weak ignition was used to ignite the mixtures of propane and air. The distribution and variation of overpressure in the pipeline were investigated with obstacles at different blocking rates, quantities and spacing.

Key words: propane ; explosion ; overpressure ; obstacle
