摘要

为了探究网状高分子材料对卧式储罐油气爆炸抑制影响，设计搭建了（L/D≈3.1，V=1000L）卧式储罐实验系统，分析了抑爆材料填充率对油气爆炸特征参数的影响规律，探究了抑爆材料对油气爆炸的抑制机理。结果表明：装填网状高分子材料后，卧式储罐油气爆炸威力被显著削弱，火焰传播受到明显的阻滞作用，火焰传播速度下降；随着填充率的增加，爆炸超压最大值、平均升压速率、爆炸威力指数逐渐下降，最大超压值到达时间逐渐延长；火焰在抑爆材料内传播过程中，因受到“冷壁效应”、“器壁效应”和材料热分解作用影响，导致油气爆炸发展过程受到抑制。

Abstract

In order to explore the effect of reticular polymer material on gasoline-air mixture explosion suppression of horizontal storage tank, a horizontal storage tank experiment system (L/D≈3.1, V=1000L) was designed and built. The law of the effect of filling rate of explosion suppression material on gasoline-air mixture explosion characteristic parameters was analyzed, and the mechanism of explosion suppression material on gasoline-air mixture explosion was explored. The results show that the explosive power of the horizontal tank is significantly weakened, the flame propagation is retarded, and the flame propagation speed decreases after the filling of the mesh polymer material. With the increase of filling rate, the maximum explosion overpressure, the average pressure boost rate and the explosion power index gradually decrease, and the arrival time of the maximum overpressure gradually prolongates. In the process of flame propagation in the explosion suppression material, Due to the influence of "cold wall effect", "wall effect" and material thermal decomposition, the development process of oil and gas explosion is inhibited.
