摘要
本文基于SACTI模型和整年气象数据,选取某厂址三台大型自然通风冷却塔布局对正常工况条件下冷却塔所致局地环境影响进行数值模拟研究。研究中分析了三台冷却塔运行过程中雾羽荫屏、漂滴沉降和盐沉积对环境的影响,分析和评估了四季和年均条件下冷却塔对周围环境的影响。结果表明,厂区三台冷却塔同时运行条件下,四季和年均结果中全年最大阴影时间约为782.4 h、地面沉积水量最大值为0.24 mm/a,盐沉积最大值为158.91 kg/(km^(2)·mon),对周围环境影响较小,不会对周围农作物和其他植物产生明显影响。
This study conducted a numerical simulation based on the SACTI model and year-round meteorological data to evaluate the local environmental impacts of three large natural draft cooling towers at a specific site under normal operating conditions.The analysis focused on the effects of plume shadowing,drift deposition,and salt deposition during the operation of the cooling towers.Seasonal and annual impacts on the surrounding environment were assessed.The results indicate that,under simultaneous operation of the three cooling towers,the maximum annual shadow duration is approximately 782.4 hours,the maximum ground water deposition is 0.24 mm/a,and the maximum salt deposition is 158.91 kg/(km^(2)·mon).These impacts are minimal and are not expected to have significant effects on nearby crops or other vegetation.
