摘要
通过运用ADMS模型,对2万m3原油储罐发生火灾爆炸事故时有毒有害气体及燃烧次生污染物的环境影响进行预测。结果表明,其产生的废气污染物对环境影响较大;在火灾持续6h的情况下,产生的主要废气污染物在距离事故中心120m范围内的人员将有半数死亡;距120～240m范围内造成组织缺氧;距240～4725m人员不会有生命危险;距离4725m范围内污染物的浓度超出车间最高允许浓度要求。同时提出了相应的环境风险管理措施,为今后类似事故环境影响评价作借鉴,为环保部门环境管理提供参考。
By using the ADMS model, in this paper, the environmental influence of toxic and harmful gas emissions and associated/secondary pollution is forecasted during fire ＆ explosion accident of 2 × 104ms crude oil storage tank. The results show that it has a great influence on environment, under the condition of 6 h burning, the produced gas pollutants will cause half people die within 120 m of the accident center, hypoxia in the range of 120-240 m, and won＇t cause life risk in the range of 240-4 725m. Pollutants concentration at 4 725 m will exceed the maximum value of workshop limit value. Corresponding management measures for the environment risks are put forward. It provides reference for the environmental impact assessment of alike accidents, and the management of environmental protection agencies in the future.
