防爆墙对某厂区LPG管网泄漏-爆炸事故后果的影响
Effects of explosion-proof wall on the leakage-explosion accident of LPG pipe network in a factory
摘要
Abstract
A quantitative study was conducted using FLACS software to assess the mitigation effects of explosion hazards caused by LPG pipeline leakage in a petrochemical plant in Shaanxi,with a focus on reducing explosion risks by installing blast walls between the facility area and the office-living zone.The study investigated the blast mitigation performance of the blast walls by analyzing their position D(the distance between the blast wall and the leftmost edge of the office-living zone),height H,and thickness d.The results demonstrated that the farther the blast wall is from the explosion source and the closer it is to the office-living zone,the better the protective effect on the office-living zone.For a 24 m high building within the office-living zone of the petrochemical plant,when the blast wall was posi-tioned 5 m from the office-living zone with heights of 3 m and 11 m,the corresponding reductions in o-verpressure behind the wall were 52.20％and 70.33％,respectively.For blast wall thicknesses d of 0.1,0.3,0.5 m and 0.7 m,the corresponding overpressure reductions behind the wall were 68.29％,67.44％,66.80％,and 66.41％,respectively.For rigid structural blast walls,the height of the wall has a more significant impact on reducing overpressure behind the wall compared to its thickness,indi-cating that the design of blast wall height is more critical for explosion prevention and mitigation.The simulation results provide a reference for proactive hazard protection in the petrochemical plant.关键词
