Theory, characteristics, parameters, construction methods of explosion-proof pressure relief panels
Definition of explosion
Explosion is a very rapid chemical or physical change process of matter,
Rapidly releasing a huge amount of energy during the change process heat and generate a large amount of gas. At this time, the gas still exists in a limited space for an instant, so it has a huge pressure, which exerts strong pressure on the objects around the explosion point. When the high-pressure gas expands rapidly, an explosion is formed.
The principle of physical injury and property loss caused by explosion
The physical principle of explosion fragments causing casualties and property loss. The explosion causes some shells to break into pieces or pieces flying around. These are fragments with higher velocity or greater mass. It has greater kinetic energy during flying out and can cause greater harm. The degree of damage caused by debris depends on its kinetic energy, which is proportional to the square of its mass and speed. The fragments often have an initial velocity of / when leaving the shell, and even when flying far away from the center of the explosion, they also have a speed of /. At this speed, the kinetic energy of the fragments with mass is enough to cause serious injury or death. Debris with sharp edges greatly increases the chance of life-threatening injuries. Debris may also damage nearby equipment and pipelines, causing continuous explosions or fires, causing greater harm.
Explosion Venting Theory
During indoor deflagration, the critical pressure can be instantly relieved by leaking the explosion pressure through building structural components. At the same time, by controlling the quality and explosion characteristics of the explosion fragments, the explosion shock wave can be effectively reduced. The probability of personal injury and property damage from debris.
