biogas and gas pipelines

窨 窨 受 受 受 受 受 受 受, connecting the septic tank, the sewage, feces, and dead branches will produce biogas.The main ingredient is methane, which is a combustible gas. When it encounters an open fire and the concentration value reaches the limit, it will explode.

According to Guo Yiyuan, deputy director of the combat training office of Guiyang Fire Rescue Detachment, it is a limited space. If no one is cleaned for a long time, the methane concentration in the well is within the limit of the explosion.What may cause is a big event.[The concentration range of the explosion caused by a bright fire after mixing between methane and air is 5%to 15%.】

In addition to methane, the organic matter concentration and sulfate content in sewage sewage are high, and chemical reactions will generate hydrogen sulfide.Under standard conditions, hydrogen sulfide is a flammable acidic gas, colorless and toxic, and has a smell of eggs with stinky eggs when low concentration. It can form explosive mixture with air. In encountering light fire and high fever, it can also cause combustion and explosion. In addition, Guo Youyuan mentioned that there may be gas pipelines in the cities of the city. If the underground gas pipeline is leaked, the leaky gas is accumulated in the well, and the firecrackers thrown out are caused by a series of explosions.
