摘要:
为研究抛光铝粉的爆炸危险和ABC粉体的抑爆特性,在对实验粉体粒径分布进行分析的基础上,采用20 L粉尘爆炸特性实验装置,分别对不同铝粉尘浓度、不同抑爆剂浓度条件下的爆炸特性参数进行测试。研究结果表明:在实验条件下,铝粉的爆炸下限为45 g/m3<C<60 g/m3;随铝粉浓度增加,爆炸烈度呈现出先增强后减弱的变化趋势,在浓度为400 g/m3时爆炸烈度最大。ABC抑爆剂能够有效抑制铝粉爆炸超压和爆炸反应进程,随着惰性粉体浓度的增加,抑制效果愈加明显,爆炸逐渐减弱。当ABC惰性粉体的质量占比增加到50%时,相较单一铝粉爆炸,反应过程时间由72 ms增加至785 ms,爆炸最大压力、最大压力上升速率分别下降了61.7%,89.5%;当ABC粉体质量占比为53%时,铝粉被完全惰化,未发生爆炸。
Abstract:
In order to study the explosion risk of polished Aluminum powder and the explosion suppression characteristics of ABC powder,on the basis of analyzing the particle size distribution of experimental power,the explosive characteristic parameters under different concentrations of Aluminum powder and explosion suppressant were tested respectively by using the 20 L dust explosion characteristics experimental device.The results showed that the lower explosion limit of Aluminum powder was 45 g/m3
