摘要:
天燃气安全不仅仅局限在企业内部，而是面向全社会，关系到社会稳定和市民生命财产安全。随着天然气市场开拓和广泛利用，庞大的管网系统和多样的用气环境给安全工作提出了更高的要求。采用理论分析、实验研究相结合的方法研究了管道内天然气爆炸火焰及压力波的传播规律。应用直径为700mm，长度为93m的管道进行了三次天然气爆炸传播实验。得出爆源点最大压力值并不是整个爆炸过程的最大值；压力波最大压力值在爆源点附近先降低，然后上升到某一峰值之后再逐渐衰减；最大压力值在衰减过程中不是单调衰减，有点起伏；随着天然气浓度的增大，其爆炸平均升压速率反而减小；随着天然气浓度的增大，其爆炸平均升压速率反而在减小；爆源附近火焰传播速度较小，上升到某一峰值后逐渐衰减。
Abstract:
The safety of natural gas should move beyond gas companies to the broad society, because it can affect the social stability and people’s life and property. As the natural gas market expands and diversifies, the ever growing pipeline network and increasing situations where natural gas is needed put challenges to the safety management. This research on the flame and pressure wave propagation laws of natural gas explosion in the pipeline by theory analysis, experiment research and numerical simulation.Application of a diameter of 700mm and a length of 93m pipeline for propagation of natural gas explosion experiments three times. Maximum pressure of explosion source is not the maximum pressure of whole process; the maximum pressure values of pressure wave decreases in explosion source nearby, then rises to a peak value and weakens gradually; maximum pressure value decay process is not monotonous, and has fluctuations; with the gas concentration increases, the average explosive setup speed decreases instead; flame propagation speed near the explosion source is very small, then rising to a peak value and weakens gradually. This research provides a basis for relevant data for further revealed the propagation laws of natural gas explosion in pipeline.
