摘要

对甲醇-氨-空气多元爆炸性混合气体的爆炸特性与爆炸形态进行了系统的研究，结果表明：甲醇-氨-空气(甲醇∶氨=1∶1.1)爆炸性混合气体的浓度爆炸极限为12.85%～45.25%；该爆炸性混合气体爆炸只有冷焰与爆燃2种形态，不会出现强烈的爆轰现象；氮气与水蒸气对甲醇-氨-空气爆炸性混合气体爆炸具有一定的惰化作用；氨对甲醇-空气爆炸性混合气体爆炸具有明显的阻尼效应，随着甲醇/氨的比值降低，其爆炸危险度、爆炸最高压力以及压力上升速率均会降低。用于指导甲醇氨氧化的工业生产的技术改造，具有抑爆效果好、防爆措施有力、生产能力大幅度增加、经济效益明显等特点。

Abstract

Systematic studies were carried out to investigate the explosion characteristics and morphology of the multicomponent explosive gas mixture CH3O-NH3-air.It was found that the explosive limit of concentration of the gas mixture (CH3OH∶NH3=1∶1.1) was 12.85%—45.25%.There were only two explosion morphologies for the explosive gas mixture.One is cool flame

and the other is deflagration.Furthermore

strong detonation was not observed during the explosion experiments.N2 and steam did have some inert effect on the explosion of the explosive gas mixture

while NH3 had a clear damping effect on the explosion for the gas mixture with CH3OH and air.With the decrease of ratio of CH3OH to NH3

the degree of explosive danger

explosion maximum pressure and pressure rise rate decreased at the same time.The present work provides a good guidance for the technological upgrade of methanol ammoxidation in industrial production due to its good effectiveness of explosion suppression and powerful explosion-proof measure.It also has a potential application of methanol ammoxidation because of its substantial increase in productivity

low investment

rapid implementation

and high economic benefits.
