The reason why acetylene bottles must be upright when stored and used

Reason 1: The acetylene bottle is equipped with filler and solvent (acetone). When it is used horizontally, acetone is easy to flow out with the acetylene flow, which not only increases the consumption of acetone, but also reduces the combustion temperature and affects the use. At the same time, it will cause tempering and cause the acetylene bottle. explosion accident.

The acetylene in the cylinder is dissolved in the acetone solvent under pressure. When the valve is opened, the pressure is reduced, and the dissolved acetylene becomes a gas and is released. Placing the acetylene cylinder horizontally may cause acetone to flow out. The acetylene dissolved in acetone will volatilize rapidly and mix with air to form an explosive mixture. Explosion limit: 2.3%-72.3% (vol), minimum ignition energy: 0.019mJ, Thermal energy causes combustion and explosion. It not only increases the consumption of acetone, but also reduces the combustion temperature and affects the use. At the same time, it will cause tempering and cause the explosion of the acetylene bottle; in addition, the pressure will blow out the solvent and dissolved acetylene, which will cause the acetylene pressure to rise and explode.

Reason 2: When the acetylene bottle is lying down, it is easy to roll, and the bottle and the bottle, and the bottle and other objects are easily impacted, forming an excitation energy, resulting in the occurrence of the acetylene bottle accident.

Reason 3: The acetylene bottle is equipped with an anti-vibration rubber ring, the purpose of which is to prevent collisions during loading, unloading, transportation and use. The apron is an insulating material. Lying down is equivalent to placing the acetylene bottle on an electrical insulator, so that the static electricity generated on the gas bottle cannot spread to the ground and accumulate on the bottle body, which is easy to generate static sparks. When there is acetylene gas leakage, it is very easy to cause fire and explosion accidents.

Reason 4: The valve of the acetylene bottle is equipped with a pressure reducer, a flame arrester, and a hose connected to it. Because it is easy to roll when lying down, it is easy to damage the pressure reducer, flame arrester or pull off the rubber tube when rolling, causing the acetylene gas to be released to the outside. , resulting in a combustion explosion.

To sum up, the acetylene cylinder must be placed upright.
