摘要/Abstract

摘要： 为探究苯蒸气爆炸/燃烧火焰传播特性,在自主设计加工的长度1 m的透明可视化爆炸试验管道内,开展不同浓度苯蒸气的爆炸/燃烧试验,利用高速摄像仪拍摄管道内不同浓度苯蒸气爆炸火焰传播图像,并对比研究火焰图像。结果表明:低浓度苯蒸气-空气预混气体点燃后发生剧烈爆炸反应,随着苯蒸气浓度的升高,剧烈爆炸反应转为温和燃烧反应;火焰传播平均速度随苯蒸气浓度的增大而增大,在苯蒸气体积分数为2.8%时,火焰传播平均速度达到最大值,之后,随着苯蒸气浓度的增大而减小;低浓度苯蒸气爆炸火焰传播过程经历了急剧加速、急剧减速、缓慢加速和缓慢减速4个阶段,高浓度苯蒸气火焰传播速度基本保持不变,火焰形态与火焰传播速度密切相关。

Abstract: In order to explore the propagation characteristics of explosion and combustion flame of the benzene vapor, explosion and combustion experiments of different concentrations of benzene vapor were carried out in a self-designed 1m transparent explosion test pipeline. The high-speed camera was used to capture images of flame propagation of benzene vapor explosion in the pipeline. The flame images were compared and analyzed. The results show that a violent explosion reaction occurs when the low concentration of premixed benzene vapor-air gases are ignited, and the violent explosion reaction turns into a mild combustion reaction with the increase of concentration of benzene vapor in the premixed gases. The average flame propagation velocity increases with the rise of benzene vapor concentration, and reaches a maximum when the volume fraction of benzene vapor is 2.8%. Then the velocity decreases with increasing benzene vapor concentration. The propagation process of explosion flame of low concentration benzene vapor can be divided into four stages: a rapid accelerating stage, a rapid decelerating stage, a slow accelerating stage and a slow decelerating stage. The propagation speed of high-concentration benzene vapor flame basically keeps constant, and the flame shape is closely related to flame propagation speed.
