有毒气体对含菌超细水雾降解与抑制甲烷爆炸的影响研究
Experimental Study on Impacts of Poisonous Gas on Methane Degradation and Explosion Inhibition by Ultra-Fine Water Mist Containing Bacteria
摘要
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.关键词
