摘要
统计近10年的氨气事故,并分析事故造成的损失。表明连续点源泄漏、扩散为高频事故类型。比较分析氨气泄漏及扩散模型,选高斯烟羽模型,用Visual Basic程序,编制氨气连续点源泄漏的情况下,编制模拟氨气扩散范围的"扩散模拟软件"。这个软件可以模拟不同破裂面积、压力、温度以及天气情况下,氨气泄漏的影响范围。本软件操作简单,输入参数少,使用方便,可以为企业或政府应急疏散提供参考。
The accidents of ammonia leakage and their loss in the last decade were analyzed. The statistical results show that the continuous point-sources leakage was the high-frequency accidents. The models for ammonia leakage and diffusion were discussed. A program for ammonia leakage and diffusion was established based on Gaussian model and Visual Basic software. The consequent scope of ammonia leakage accident under different conditions could be simulated and predicted. This program could provide consults to industry and government due to its benefits of simplicity and visualization.
