摘要:
通过搭建小尺寸实验平台,研究了含甲烷氧化菌的超细水雾对含有一定体积分数的一氧化碳、硫化氢、二氧化硫的甲烷气体爆炸的降解与抑制效果,分析了甲烷降解率、甲烷单加氧酶活性的变化以及甲烷爆炸过程的变化状况。单因素实验结果表明单一的CO,H2S或者SO2对含菌超细水雾降解甲烷并无明显影响; 多因素实验结果表明φ(CO):φ(H2S):φ(SO2)=0.1%:0.003 3%:0.025%时,有毒混合气体对实验管道内甲烷降解率产生了明显的抑制作用,使得甲烷的降解率下降。有毒气体对甲烷爆炸的火焰外观形态并未产生明显影响,爆炸产生的火焰经历了“指形”—“郁金香形”—“指形”的变化过程,整个过程火焰呈现亮黄色,这与含甲烷氧化菌的超细水雾中含有大量的钠离子有关。
Abstract:
By setting up a small-sized experimental platform, the impacts of the ultra-fine water mist containing methane-oxidizing bacteria on the degradation and explosion of the methane gas with a certain volume fraction of CO,H2S,SO2 are studied, the methane degradation efficiency, the activity change of methane monooxygenase and the change of methane explosion process are analyzed. The single-factor experimental result indicates that single CO,H2S or SO2 has no obvious effects on the methane degradation of the ultra-fine water mist containing methane-oxidizing bacteria. The multi-factor experimental result indicates that the methane degradation efficiency and the activity of MMO come to the lowest when the volume fraction of CO, H2S and SO2 is 0.1%, 0.003 3% and 0.025%, respectively. The methane degradation efficiency is decreased obviously. Poisonous gas has no obvious effects on the flame appearance, the flame produced by the explosion experiences the changing process of “finger-type” —“tulip-type” —“finger-type”, the flame appears luminous yellow during the whole process, which relates to a mass of sodion of the ultra-fine water mist containing methane-oxidizing bacteria.
