摘　　要：为研究隔离墙对高含硫化氢气体泄漏事故中硫化氢扩散的阻隔作用,采用DNV KFX软件模拟有无隔离墙及隔离墙位置、高度等参数变化时的硫化氢扩散过程。研究结果表明:通过设置隔离墙可有效阻隔硫化氢扩散,延长应急响应时间;隔离墙设置位置距泄漏源距离较近时,其对气云的阻隔效果更好,隔离墙高度的增加也能有效提高阻隔效果,应结合现场安全间距和成本合理优化。研究结果可为硫化氢防护隔离墙的设计提供一定指导。To study the barrier effect of isolation walls on the diffusion of hydrogen sulfide in high⁃sulfide gas leakage accidents,DNV KFX software was employed to simulate the diffusion process of hydrogen sulfide with and without isolation walls,as well as different parameters such as the position and height of isolation walls.The results indicate that setting up isolation walls can effectively block the diffusion of hydrogen sulfide and prolong emergency response time;when the location of the isolation wall is close to the leakage source,its barrier effect is better,and increasing the height of the isolation wall can also effectively improve the barrier effect,and it should be optimized reasonably with the consideration of on⁃site safety distance and cost.The research results can provide guidance for the design of hydrogen sulfide protective isolation walls.
