摘要
复杂地形对有毒有害气体扩散后果影响显著.研究了山区地形下的某集输站场发生事故泄漏时高含硫气体的运动规律,分别开展风速为1 m/s和2 m/s、8 个风向条件下气体扩散分布规律环境风洞模拟实验,得到了不同位置的气体浓度等值线.结果表明,高含硫气体在复杂地形下的近场扩散行为主要是由风场主导,而远场扩散后果则受地形影响明显.风洞试验可为石化行业高危气体泄漏扩散风险评估和应急响应提供可靠数据支撑.
Abstract
Complex terrain has a significant effect on the diffusion of toxic and harmful gases.The move-ment law of high-sulfur gas in a gathering station un-der mountainous terrain during an accident leakage was studied.Environmental wind tunnel simulation experiments on gas diffusion distribution law under wind speed of 1 m/s and 2 m/s and 8 wind directions were carried out respectively,and gas concentration contour lines at different locations were obtained.The results showed that the near-field diffusion behavior of high sulfur gas under complex terrain was mainly dominated by wind field,while the far-field diffusion effect was obviously influenced by terrain.Wind tun-nel tests can provide reliable data for the risk assess-ment and emergency response of high-risk gas leakage and diffusion in the petrochemical industry.
