In oxygen bottle filling process, as oxygen is constantly filled with steel cylinder, by The Ideal-Gas Equation it is found that steel cylinder pressure
Power can rise rapidly, will be sent out if steel cylinder existing defects or filling process appearance exception cause pressure to bear the limit more than steel cylinder
Raw explosion accident.Explosion in oxygen bottle filling process is generally divided into physical explosion and chemical explosion, the energy of the latter's release
More, destructive stronger, caused by lose it is often more much larger than physical explosion, and with regard to the statistics of presently relevant accident from the point of view of,
Chemical explosion accident is more.Chemical explosion is typically that a certain amount of grease, in filling process, grease have been mixed into oxygen bottle
Oxidation reaction occurs with high pressure oxygen, releases heat, when the amount of grease is less, the result of reaction can only make oxygen temperature liter
Height will not substantially explode.But at this time if there is incendiary source, such as frictional heat or the electrostatic of accumulation when closing cylinder valve
Release generates electric spark, will make reacting aggravation suddenly and lighting grease for grease and oxygen, and then cause explosion；It is also possible to
It is that the gases such as H2, C2H2 have been mixed into oxygen bottle, in filling process, fuel gas reacts with oxygen and then occurs quick-fried
It is fried.
What Oxygen charging station mostly used at present is to fill worker during cylinder filling and patrolled with the method that hand touches bottle wall
It returns and checks whether bottle wall temperature is normal, and abnormal person stops filling immediately.It has a defect that：Cannot be scented a hidden danger steel at the first time
Bottle causes at the first time to handle hidden danger steel cylinder.
