为了更好研究不同点火能量下瓦斯爆炸初期光学特征,为瓦斯爆炸的快速抑爆积累经验数据,实验从瓦斯爆炸点火能量出发,构建稳定可靠的变点火实验平台,并利用强弱2种比较极端的点火能量来引爆管道瓦斯,然后利用高速摄影仪进行拍摄,通过MATLAB软件分析高速摄影仪所捕获的照片,最终得到了不同点火能作用下瓦斯爆炸初期光学特性三维规律,指出强弱点火能作用下瓦斯爆炸初期反应都存在3个阶段,弱点火存在瓦斯爆炸低速反应阶段,快速增加阶段,稳定发展阶段,强点火存在瓦斯爆炸反应速率急速衰减阶段,快速增加阶段,稳定发展阶段。
In order to better study the optical characteristics of early gas explosion under different ignition energies and accumulate experience data for rapid explosion suppression of gas explosion, the experiment starts from the ignition energy of gas explosion and builds a stable and reliable variable fire experiment platform. Ignition energy to detonate pipeline gas, and then use the high-speed camera to shoot, through MATLAB software analysis of high-speed camera captured photos, and finally get the different ignition can play a three-dimensional law of the initial optical characteristics of gas explosion, pointed out that the strong and weak ignition can function In the early stage of gas explosion, there are three stages of reaction. There is a low-speed gas-explosion reaction stage in the weak-point fire. The stage of rapid increase and stable development is characterized by rapid fire decay, rapid increase and stable development.
