摘要:
为了得出实际管网中瓦斯爆炸冲击波、火焰波的普适性传播特性，搭建了角联管网实验系统。通过平均升压速率和爆炸威力指数表征冲击波传播特性；通过火焰传播速率表征火焰波传播特性。结果表明：冲击波在角联管网中传播时出现了多次衰减与叠加，冲击波的正向传播和冲击波在管网所有互连管道中的反向传播叠加在一起，导致冲击波的传播呈现复杂无序状态。冲击波传播在不同的管道结构时，经过45°分岔管道时爆炸威力最大；在斜角联支管中，压力损失最大，超压爆炸威力下降幅度最大，火焰波传播速率最快；底部直管中的火焰波传播速率最慢。可为瓦斯爆炸灾害发生后应急救援方案的制定提供理论参考。
Abstract:
In order to obtain the universal propagation characteristics of gas explosion shock wave and flame wave in the actual pipe network, a diagonal pipeline networks experimental system was built. The shock wave propagation characteristics were characterized by average pressure rise rate and explosion power index, and the flame wave propagation characteristics were characterized by flame propagation velocity. Results show that the shock wave propagates in diagonal pipe networks with multiple attenuation and superposition. The forward propagation of the shock wave and the reverse propagation of the shock wave in all interconnected pipes of the pipe network are superimposed together, resulting in a complex and disorderly propagation of the shock wave. When the shock wave propagates in different pipe structures, the explosion power is the largest when it passes through 45° bifurcated pipes. In diagonal branch pipe, the pressure loss is the largest, the decline in explosive power is the largest, and flame wave propagation speed is the fastest. The flame wave propagation speed in the bottom straight pipe is the slowest. The obtained conclusions can provide a theoretical reference for the formulation of emergency rescue plans after gas explosion disasters.
