基于SLAB模型的有色金属冶炼行业涉SO₂泄漏环境风险事故研究

Research on Environmental Risk of SO₂ Leakage Accidents in Non-Ferrous Metal Smelting Industry Based on SLAB Model

摘要: 本文以某铜冶炼厂贮存的涉SO₂泄漏风险事故为研究对象，基于SLAB模型，模拟了最不利气象条件及当地常见气象条件下，高浓度管道SO₂泄漏、管道SO₃泄漏及液态SO₂储罐泄漏下产生的环境风险影响。文章结果给出了泄漏事故发生后的危险区域及范围。同时根据预测结果，文章针对性地提出了有效风险防范措施，为有色金属冶炼企业制定应急方案提供参考。

Abstract: This article was research on environmental risk of SO₂ leakage accidents in a copper smelter indus-try based on SLAB Model. The environmental risk effects of high concentration pipeline SO₂ leakage, pipeline SO₃ leakage and liquid SO₂ storage tank leakage under the most adverse meteorological conditions and common local meteorological conditions were studied. According to the results, the range of dangerous area after leakage accident was given. At the same time, according to the predic-tion results, this paper puts forward effective preventive measures, which provides a reference for non-ferrous metal smelting enterprises to formulate risk emergency plans.
