摘要：

为分析聚偏氟乙烯(PVDF)球形多孔材料对管道内甲烷-空气预混气体的抑爆性能,自主搭建气体爆炸测试平台,试验研究球形多孔材料填充密度及填充方式等因素对甲烷-空气预混气体爆炸的影响机制。结果表明:与空爆相比,填充多孔材料后,管道内爆炸超压及最大爆炸超压上升速率均明显降低;对甲烷-空气的抑制效果与材料的填充密度呈正相关,当填充密度为0.077 g/cm³时,球形多孔材料对爆炸超压的抑制率达到54.7%,最大爆炸超压上升速率降低了58.3%;改变材料的填充方式显著影响管道内的气体爆炸超压,采用分散填充的方式增强了多孔材料对最大爆炸超压的抑制作用,在填充密度(为0.038 5 g/cm³时)不变的情况下,对管道末端气体最大爆炸超压的抑制率达到66%。说明改变材料填充密度和填充方式均会影响多孔材料对甲烷-空气预混气体爆炸的抑制效果。

Abstract:

In order to analyze the explosion suppression performance of PVDF porous spherical material on methane-air premix gas in the pipeline, a self-built gas explosion test platform was used to explore the influence mechanism of factors such as filling density and filling method of spherical porous material on the explosion of methane-air premix gas. The results show that compared with air explosion, the explosion overpressure and the ratio of the maximum explosion overpressure in the pipeline are reduced after filling the porous material. The inhibition effect of methane-air is positively correlated with the filling density of the material. When the filling density is 0.077 g/cm³, the inhibition rate of the spherical porous material on the explosion overpressure reaches 54.7%, and the ratio of the maximum explosion overpressure decreases by 58.3%. The different methods of material filling obviously impact the pipe gas explosion overpressure. The dispersed filling method enhances the suppression effect of the porous material on the maximum explosion overpressure. When the filling density is the same, 0.038 5 g/cm³ of material reaches 66% of the suppression efficiency on the maximum explosion overpressure. The inhibition effect of porous materials on methane-air premixed gas explosion will be affected by changing the filling density and filling method.

Key words: polyvinylidene fluoride(PVDF), porous spherical material, explosion suppression performance, explosion overpressure, filling density, filling method
