摘要:
基于区域网格划分技术及高斯烟团模型,综合储罐泄漏速度、有效源高(泄漏高度),以及风向、风速、环境稳定级多因素变化,研究区域内一个或多个储罐中有毒有害物在连续时间内浓度分布规律。首先,以储罐为中心,将研究区域网格化为若干单元作为定量研究和叠加的基础;然后,运用高斯烟团理论构建有毒有害物的泄漏扩散浓度分布模型;最后,结合单泄漏源和多泄漏源条件,给出有毒有害物连续性扩散算法,即根据任意影响因素的变化来划分时间段,按时间顺序,结合浓度叠加效应,使用Matlab,模拟区域内有毒有害物浓度过程。模拟结果表明,该项研究可为化工园区储罐布置复杂条件下,有毒有害物突发性泄漏事故的影响范围预测及应急决策提供理论支持。
Abstract:
According to the techniques of regional meshing and Gaussian plume modeling, combining the variation of multi factors, such as the tanks leak velocity, the leak height, the wind direction and speed, and the environmental stabilization grade, the concentration distributing rules of the noxious substances with continuous diffusion in the tank farm were studied. Firstly, taking the tank as center, the meshing on research area to a certain units was conducted as the basis of quantitative analysis and superposition calculation. Secondly, the diffusion concentration distributing model of the noxious substances leakage was established based on Gaussian plume theory. Finally, by the combination of single leakage source and multiple leakage source, the continuous diffusion algorithms of noxious substances were presented, viz. in accordance with the variation of any influence factors, the time sections were divided, then basing on the Matlab, integrating the concentration superposition effects, the concentrated distribution process of noxious substance in the influence areas was simulated. It showed that the method may provide theoretical support for influence range prediction and emergency decision for unexpected leakage accident of noxious and hazardous substance under the complex conditions of tank layout in chemical industry park.
