What is the principle of methane deflagration caused by men squatting in toilets in Hebei?

1. What is the situation of methane deflagration induced by men squatting in toilets in Hebei? A man had an accident while smoking at home in Langfang, Hebei. The man intended to squat in the toilet to smoke, but when he lit a cigarette with a lighter, the bathroom suddenly exploded. Finally, the ceiling of the bathroom was deformed by the explosion and fell down. Some burnt marks can be seen on the bathroom wall, and even the window glass of their balcony has been broken. The man's body was also burned in the dark on the spot. Finally, the man was sent to a local hospital for treatment, and the total body burn area actually reached 80%. After firefighters arrived at the scene, the explosion had already occurred. It is preliminarily judged that the explosion was caused by excessive methane gas.

Second, what is the principle? ? People living in rural areas are no strangers to biogas, because many people have biogas digesters at home. The main component of biogas in biogas digesters is methane, which is methane gas produced by the accumulation and fermentation of human and animal feces. Therefore, the explosion is probably due to the continuous accumulation of methane gas in the sewage pipes in residential buildings. After reaching a certain level, these methane gases will enter the toilets of some families along the toilet pipes. After encountering a little open flame, these methane gases will enter the toilets of some households.

Third, how to avoid this danger? Under normal circumstances, methane gas explosion in residential buildings like this one, on the one hand, is due to the early construction of the residential area, so the interior of the pipeline is aging or even blocked, and part of the reason is probably that the residential property did not treat the sewage pipeline and septic tank in time, which led to excessive accumulation of methane gas and caused an explosion. Therefore, to avoid this danger, we must bear our own responsibility as property. Clean the septic tank regularly. In addition, some old and blocked pipelines should be replaced or cleaned in time, so that the explosion caused by methane gas accumulation will not occur.
