The on-line explosion-retarder is a safety accessory installed on the pipeline transporting flammable gas or flammable liquid vapor to prevent the flame caused by tempering or other reasons from spreading and spreading to the pipeline or other equipment. It can effectively prevent the spread of flame, protect the pipeline system and related equipment from damage, and ensure production safety.
The working principle of on-line flame retarder is mainly based on heat transfer and wall effect. When the flame passes through many small channels of the fire blocking element, the flame is cut into a number of small flames, which expands the contact area between the flame and the channel wall, strengthens the heat transfer, and rapidly reduces the flame temperature to below the ignition point, thereby preventing the spread of the flame.Explosion-proof flame arrester with breathing valve At the same time, the collision probability between the free radicals generated in the combustion process and the channel wall increases, and the number of free radicals participating in the reaction decreases. When the channel is narrow to a certain extent, the collision between the free radicals and the channel wall dominates, and the number of free radicals decreases sharply, resulting in the combustion reaction cannot continue, thus preventing the spread of the flame.
