Based on comparison and practice, necessity and reliability of us- age of new self-closing gas safety valves in gas purification systems are presented.

Study on Quenching of Dust Explosion Venting;

Numerical simulation of the vented explosion process of premixed gas in the communicating vessel;

Experimental investigations of external second-explosion induced by vented explosion;

A methane-air mixture explosion venting process is numerically investigated in terms of Euler equations coupled with the element chemical reactions.

These problems include high explosion venting rate of electrostatic precipitator, high equipment failure rate, poor performance of evaporative cooler nozzle, the production of high maintenance costs, large fluctuation of the dust contained in the flue gas and other issues.

The concept of explosion venting encompasses all measures used to open the originally closed vessels and equipment either briefly or permanently in a non-hazardous direction following an explosion and explosion venting technology describes one of the possible protective measures against the effect of explosions.

Pressure measurement inside and outside the vessel during venting explosions;

By analyzing the experiment of the draining duct,this paper puts forward the opinion that the draining duct can be added to the guide place of finished detonator,which can promptly drain off the wave produced by the explosion of detonator and greatly enhance the safe production.
