چکیده انگلیسی
Safety issues are of particular importance in low-concentration gas delivery. The gas explosion propagation rule and the effects of an active powder-spraying explosion-suppression device on a gas explosion in a pipeline were experimentally studied by using an experimental system with Φ500â¯mm pipeline explosion suppression. The research demonstrates the gas explosion pressure and flame propagation law that were obtained in the 500-mm pipe. In combination with the action time of the active powder-spraying explosion-suppression device, its installation position in the gas transmission pipeline was determined. The active powder-spraying explosion-suppression device exhibits a clear inhibitory effect on the flame and explosion pressure of a gas explosion in the pipeline, and the inhibitory effect varies with the amount of suppressant used. Under experimental conditions, a 10-kg explosion-suppression agent can successfully suppress the explosion flame, while the explosion pressure will be greatly attenuated. The conclusions provide an important theoretical basis for effectively suppressing a gas explosion in the low-concentration gas transportation process.
