摘要
简述了德国"烟塔合一"类大气污染扩散模式,以及相关模式Austal 2000的应用方法,修正了气象参数以适合本地化应用。以天津某电厂为实例,将Austal 2000模式"烟塔合一"和烟囱排烟方式的计算结果进行了对比分析。结果表明,在进行本地化修改后,Austal 2000模式适用于国内有关项目大气预测评价,但从环境影响角度考虑,"烟塔合一"相对于高烟囱排放方式没有明显优势,应用时需慎重。
It was introduced German atmospheric dispersion model ＂cooling tower with flue gas injection＂ and related model Austal 2000 for VDI guideline application.Several meteorological parameters in Austal 2000 were modified to adapt meteorological condition where the power plant located.A power plant project in Tianjin was selected as an example to compare and analyze the Austal 2000 calculation results of flue gas exhaust by cooling tower and by high chimney.The results showed that after localized modification,Austal 2000 was suitable for the atmospheric dispersion calculation of the ＂cooling tower with flue gas injection＂ project in China.Compared with high stack emission,＂cooling tower with flue gas injection＂ project do no obvious advantages to environmentally friendly,so application of such project needed to consider carefully.
