由于城市化的快速发展，中国部分城市形成了浓厚的雾霾，城市热岛效应加剧。城市雾霾问题已经成为一个敏感的问题，严重影响着在城市生活和工作的人们。太阳上升气流塔（SUT）是一种在自然浮力的作用下将暖空气推向高空的装置。本文提出利用高SUTs将含霾的UHI暖空气提升到更高的高度，帮助霾向更远的距离扩散，从而有效降低霾浓度。该方案可以有效缓解城市雾霾问题，同时为中国城市生产清洁电力。对某热岛发电用单SUT进行了性能分析和成本分析。分别估计了中国几个主要城市UHIs中仅为推动空气上升而产生的1公里和1.5公里高sut的数量。
Due to rapid urbanization, dense haze is formed in some Chinese cities where urban heat island (UHI) effect is aggravated. The urban haze problem has become a touchy issue significantly affecting humans living and working in the cities. Solar updraft tower (SUT) is a device that can drive warm air up to high altitude under the effect of natural buoyancy. In this paper, high SUTs are proposed to be used to drive the UHI warm air containing haze up to higher altitude and help the haze disperse to farther distance, thus lowering the concentration of haze effectively. This proposal can effectively alleviate the urban haze problem and simultaneously produce clean electric power in Chinese cities. The performance analyses and cost analyses of sole SUT for power generation in a UHI are conducted. The number of 1 and 1.5 km high SUTs only for impelling air up in UHIs of several main Chinese cities are estimated, respectively.
