摘要:
为研究仓储罐区构建筑物对重质气体泄漏扩散行为的影响,采用可视化技术与定量检测技术在油库罐区模拟实验平台上开展了重质气体泄漏扩散实验。对不同形状、不同截面长度障碍物设置工况下重质气体泄漏扩散行为进行可视化和定量检测研究,获得罐区重气泄漏扩散规律的可视化和定量数据。结果表明:可视化研究直观揭示了罐区重质气体泄漏扩散的全过程,揭示了泄漏扩散重质气体到达障碍物后的扩散行为; 障碍物对重质气体泄漏扩散行为的影响很大,且面向泄漏源侧的障碍物截面长度越长,对泄漏扩散过程的影响越大,重质气体越容易在障碍物附近集聚,形成高浓度区域并保持较长时间,事故风险越高; 相同截面长度不同形状的障碍物对泄漏扩散行为的影响基本相同,即障碍物的截面长度是影响泄漏扩散行为的关键因素。因此,罐区及邻近区域应尽量避免建设构建筑物,必须建设时应使其短边正对罐区。
Abstract:
In order to research the impact of structure buildings in storage tank farm on heavy gas leakage diffusion behaviors, the paper adopts visualization technology and quantitative detection technology to carry out heavy gas leakage diffusion experiment in oil storage tank farm simulation platform. Through the visualization and quantitative test study of setting obstacles with different shape, different cross-section length in the conditions of heavy gas leakage diffusion process, the visualization and quantitative data of heavy gas leakage diffusion behavior regularity in the tank farm are obtained. The Results indicate that the visualization research intuitively reveals the whole process of heavy gas leakage diffusion in the tank farm and the heavy gas diffusion behavior after approaching obstacles; obstacles have great influence on heavy gas leakage diffusion behavior, and obstacles which have longer cross-section length facing the leakage source side have greater impact on the leakage diffusion process, and it is easier to form high concentration area of heavy gas near the obstacles and keep a long time, the risk of accident is higher; the influence of the obstacles in different shapes but with same cross-section length on the heavy gas leakage diffusion behavior is basically the same. Thus the cross-section length of obstacles is the key factors to influence the leakage diffusion behavior. Therefore, it is better to avoid the construction of buildings in tank farms and its adjacent area. When the construction is necessary, its short side should be faced to tank farm.
