Abstract

After the gas explosion, preventing the propagation of explosion flame can better eliminate the disaster. In this paper, three kinds of nitrogen nozzle arrangement are set to carry out experiments for explosion prevention. The nitrogen pressures used in experiments include 0.1, 0.2, 0.3, 0.4 and 0.5 MPa, Nitrogen is spurted into the pipe after the occurrence of the explosion and immediately shut down after quenching the explosion. The results show that the spurted nitrogen under each pressure can not prevent the explosion with single nitrogen nozzle, which is 20 cm away from the vent. But the average propagation speed of the flame in the whole pipe decreases with the increase of nitrogen pressure. With single nitrogen nozzle, which is 35 cm away from the vent, the spurted nitrogen at pressure 0.5 MPa succeed in explosion prevention, while the explosion can not be prevented at other pressure. When double nozzle is used to spurt nitrogen, the explosion is prevented in the case of pressure 0.3, 0.4 and 0.5 MPa. And the greater the nitrogen pressure, the more forward the flame is blocked. The explosion prevention requires nitrogen to dilute the premixed gas below the combustible limit. Nitrogen volume is the important parameter affecting dilution. With single nitrogen nozzle, the situation of nozzle far from the vent is easier to prevent the explosion than that of nozzle near from the vent. When double nozzles are used, the nitrogen region will enlarge. With double nozzle, lower nitrogen pressure and less nitrogen quantity are required for preventing the explosion as comparing with single nozzle.
