【摘要】 针对目前太阳能海水淡化技术和太阳能烟囱发电技术在经济或技术上存在的问题,提出了太阳能烟囱综合利用海水系统,在利用太阳能烟囱进行海水淡化的同时,以制取的淡水进行水力发电。首先以天津汉沽地区的气象数据对综合系统的性能进行了初步估算;其次建立并优化小型实验系统,获取不同冷凝方式的实验结果。通过实验与理论估算结果的对比来分析该综合系统的理论和经济可行性。理论和实验研究结果表明:采用间壁冷凝换热方式,所提出的综合设计方案具有可行性,并同时推动太阳能烟囱技术和海水淡化技术的发展。更多还原

【Abstract】 Aiming at the economical and technical problems in the desalination and the power generation of solar chimney,the integrated system has been put forward,from which fresh water and electricity can be obtained.Firstly,the performance of the integrated system has been initially estimated based on the climate conditions in Hangu area. Secondly,a small optimized experimental system has been set up,from which the data of the direct and indirect condensation were measured.By comparing the experimental results with theoretical estimation,the economic and theoretical feasibilities of the system were analyzed.The theory and the experiment results showed that the integrated system was doable if suitable heat exchanging way was chosen,at the technologies of the solar chimney and seawater desalination will be promoted at the same time.更多还原
