摘要
对多种粉尘抑爆剂在 H2 - O2 混合物中发生的爆炸过程的抑制作用进行了实验研究 .实验在长 4.4m,内径 32 mm的燃烧管内进行 .该管分为激波生成稳定段和抑爆实验段 ,其中实验段装有专门设计的喷气扬粉系统 .根据实验结果 ,讨论了抑爆剂的颗粒浓度 ,颗粒种类 。
Suppression of explosion in H 2-O 2 mixture by several kinds of fine powder in a tube has been studied experimentally. It was conducted in a 4.4 m long, 0.032 m inner diameters tube, consisting of two sections, a shock induced and development section and a suppression section equipped with a specially designeed powder dispersion system. Based on experiments, the effects of particle kinds, mean diameters and diameter distributions on explosion suppression have been discussed in the paper.
