摘要:

为获得最适用于储油容器的多孔类抑爆材料，选择铝合金网状抑爆材料、球形非金属抑爆材料、网状聚氨酯泡沫抑爆材料等3种代表性材料，在密闭容器中开展油气爆炸抑制实验，探究其抑爆机制，分析其抑爆演变过程，对比其爆炸特性参数。结果表明：“冷壁效应”“器壁效应”及爆炸波抑制理论在油气爆炸的抑制中都起到了重要作用，但各种抑爆机制在不同材料条件下的贡献不同。在使用铝合金网状材料和球形非金属材料抑爆时，容器内超压得到了抑制，但火焰因扰动作用而快速发展，爆炸发展迅速，而在使用网状聚氨酯泡沫材料抑爆时，火焰和超压都得到了较好抑制。以最大超压峰值和爆炸威力指数为评价指标，网状聚氨酯泡沫材料的抑爆性能明显优于其他两种材料，表明其在油气安全防控领域有着重要的工程应用价值。

Abstract:

In order to explore the most suitable porous explosive suppressor material for oil storage containers, three representative materials, such as aluminum alloy mesh explosion suppressor material, spherical non-metallic explosion suppressor material and reticulated polyurethane foam explosion suppression material, are selected to carry out oil and gas explosion suppressor experiment in a closed container, to explore the explosion suppressor mechanism, analyze the explosion suppression evolution process, and compare the characteristic parameters. The results show that "cold wall effect", "wall effect" and explosion wave suppression theory all play an important role in the suppression of gasoline-air mixture explosion, but the contribution of various explosion suppression mechanisms is different when different materials are used. When the aluminum alloy mesh material and spherical non-metallic material are used to suppress the explosion, the overpressure is inhibited, but the flame develops rapidly due to the disturbance effect and the explosion develops rapidly, while when the reticulated polyurethane foam material is used, the flame and overpressure are well controlled. Taking the maximum overpressure peak value and explosive power index as evaluation indexes, the explosive suppression performance of reticulated polyurethane foam material is obviously better than that of the other two kinds of materials
