Methane ignites - what goes wrong
2 please the residential property company personnel or by clearing areas or in septic tank; to pay attention to the protection, wear protective gloves and protective masks; feeling unwell to stop cleaning work, so as not to endanger the health; 3 is the use of a sealed biogas cellar, animal excreta collection through biological fermentation. During fermentation, the concentration of fermentation material should not be too high or too low. There is an explosion limit of methane, methane explosion in the air range of 5% ~ 15%. Fermentation material concentration is too high, the liquid is easy to acidification, methane bacteria can only survive in neutral liquid. Fermentation material concentration is too low, the bacteria can not eat enough to work; 4 concentration is too high to consider osmotic pressure. In the choice of methane gas alarm, we must carefully choose, careful treatment.
To solve the problem of the high concentration of biogas septic tank, mainly take the following measures: Measures of high concentrations of methane is mainly to prevent the 1 control, installation in the presence of biogas can be methane concentration detection of combustible gas alarm, this control is one of the most important measures of high concentration of gas;
The main components of septic tank methane are 2 kinds of combustible gases, methane and carbon dioxide. A Cheng Marley lived in the Garden District 8 year old boy Wang accidentally wipe gun into residential septic tank, resulting in septic tank covers and nearby drainage covers continuous explosion, Wang was jump out of the underground gas smoke injury. Septic tank explosion caused many reasons, but the main reason is that the cleaning is not timely, resulting in high concentrations of methane underground, in case of an explosion.
