摘要
为测定ABC干粉对瓦斯爆炸的抑制作用,采用容积为20L的近球形抑爆实验系统,粒径为20.76μm,主要成分为高聚合度磷酸铵盐的ABC干粉进行瓦斯抑爆实验。实验结果表明:ABC干粉的添加能够降低瓦斯爆炸的压力;粉体浓度为0.10g/L时,抑爆效果最好;粉体的抑爆效果,不仅与粉体浓度有关,还与爆炸性混合气体中的甲烷浓度有关;点火延迟时间越长,粉体抑爆效果越差。
In order to test the inhibition effect of ABC dry powder to gas explosion,this paper used a nearly spherical explosion experiment system with 20L volume,and the ABC dry powder whose main composition is high degree of polymerization ammonium phosphate,particle size is 20.76μm.Experimental results show that： ABC dry powder could reduce the gas explosion pressure;the inhibition effect is the best when the powder concentration is 0.10g/L;the repress effect of the powder not only relected to powder concentration but also with the methane concentration in gas;with the ignition delay time become more longer,the inhibition effect become more worse.
