摘要:
为准确评估气相危险化学品从储罐中意外泄漏对周边环境的影响，以邻近建筑为研究对象，结合正交实验法，针对不同的考察指标，对影响危险气体在周边区域扩散的4个关键因素进行分析。研究结果表明：泄漏位置仅对建筑迎风面危险气体极值体积分数有较为明显的影响，不同泄漏位置造成的差异能达到23.2%。建筑密度的增加导致建筑区域面平均体积分数增加30%以上，而建筑区域危险气体极值体积分数分别降低了9.4%和30.4%。建筑与储罐组间距和建筑密度对于邻近建筑的影响强度（以极差来评价），是泄漏位置和气体种类的1.5~10倍。研究结果可为化工园区安全设计、合理规避事故风险提供参考。
Abstract:
In order to accurately assess the influence of accidental leakage of hazardous gas chemicals from storage tanks on the surrounding environment,taking the adjacent buildings as the research objects and combining with the orthogonal experimental method,four key factors affecting the diffusion of hazardous gas in the surrounding areas were analyzed with focusing on different indicators.The results show that the leakage position has a significant impact only on the extreme volume fraction of hazardous gas on the windward sides of buildings,and the difference caused by different leakage positions can reach 23.2%.The increase of building density leads to the increase of the average volume fraction of the building area by more than 30%,while the extreme volume fraction of hazardous gas in the building area is reduced by 9.4% and 30.4%,respectively.The influence of distance between nearby buildings and tank group and building density on adjacent buildings (evaluated by range) is 1.5~10 times that of leakage position and gas type.The research results can provide reference for the safety design of chemical industry parks and reasonable avoidance of accident risk.
