摘要:
搭建5 L圆柱形爆炸实验平台，在不同初始压力p0下，进行了球形非金属材料(SNM)、铝合金拉网材料(MAA)和聚氨酯多孔材料(PU)3种阻隔防爆材料对氢气爆炸压力影响的实验。结果表明，实验数据和拟合曲线整体呈现出倒U型，最大爆炸压力pmax均在氢气体积分数φ=40%时达到最大，填充阻隔防爆材料对容器底部湍流的影响更显著，底部所测pmax要大于侧壁和顶部。此外,3种材料对氢气/空气预混气爆炸都具有双重作用。当φ<20%时，对氢气均表现出抑制效果，抑制作用随p0的增大而减弱。由于冷壁效应和器壁效应，具有较大比表面积的PU抑制效果最佳，最小pmax为47 kPa，比空白组降低83.6%。当φ≥20%时，3种材料均促进氢气爆炸，促进效果随p0的增大而增强。由于材料的孔径和压缩程度均会影响容器内的湍流程度，3种材料对不同p0下pmax的增幅不同，pmax最大可增大为空白组的7.5~9.5倍。
Abstract:
A 5 L cylindrical explosion test platform was constructed to conduct experiments on the effects of three types of explosion-proof materials, namely spherical non-metallic material (SNM), aluminum alloy stretched mesh material (MAA), and polyurethane porous material (PU), on hydrogen explosion pressure under different initial pressures p0. The results indicate that the experimental data and fitting curves for the material group as a whole show an inverted U-shape. The maximum explosion pressures pmax all reach their maximum values when the hydrogen volume fraction φ=40%. The effect of the filled explosion-proof materials on the turbulence at the bottom of the vessel is more significant, resulting in a higher measured pmax?at the bottom than that at the side walls and top. In addition, all the three materials have a dual effect on the hydrogen-air premix explosion. When φ<20%, there is an inhibitory effect on hydrogen, and the inhibitory effect decreases with the increase of p0. Due to the cold-wall effect and the vessel-wall effect, PU with larger specific surface area has the best inhibition effect, with a minimum pmax?of 47 kPa, which is 83.6% lower than that of the control group. When φ≥ 20%, the three materials all promote hydrogen explosion, and the promotion effect is more obvious with the increase of p0. Both the pore size and the degree of compression of the materials affect the degree of turbulence in the vessel, resulting in different increases of pmax?at different p0 for the three materials. The porous material has the maximum increase of pmax?by 7.5-9.5 times.
