摘要 | 太陽能輔助之海水淡化系統可同時紓緩能源與水資源短缺之難題,其中利用薄膜蒸餾技術之海水淡化系統因可直接利用太陽熱能,更是各國積極發展之重點技術,其成本亦估計將具有極大優勢。 本研究提出一創新的氣隔式薄膜蒸餾裝置,本身即具有太陽能吸收功能,此一裝置將可大幅提高整座海水淡化廠之操作效益,即在日間,太陽熱能可同時直接為薄膜蒸餾模組所利用,並可儲存於儲熱設施,在夜間,薄膜蒸餾模組則可利用儲熱槽之熱能運轉。 本研究以實驗和理論探討具太陽能吸收功能氣隔式薄膜蒸餾在海水淡化系統之應用,分成二部份,即具太陽能吸收功能氣隔式薄膜蒸餾裝置之研發與應用具太陽能吸收功能氣隔式薄膜蒸餾之海水淡化廠之整廠設計與經濟評估。兩者均包括理論模式與實驗系統之建立,實驗部份除展示系統之可行性之外,可驗證模式之正確性,模式將被用以探討操作條件與設計參數之影響,並用於經濟效益分析。 Solar powered desalination technology is very promising for alleviating the energy and water resources shortage issues. Membrane distillation, being capable of directly utilizing solar thermal energy, is becoming a critical developing technology in many countries and is expected to be advantageous in cost. This project proposes an innovative air gap membrane distillation device with solar energy absorption function. The device can significantly improve the effectiveness of the solar desalination plant. At the daytime, solar energy can be utilized by the membrane distillation module and stored in the heat storage system simultaneously. At the nighttime, the membrane distillation module can be operated utilizing the energy from the heat storage system. The project will investigate the innovative device and the overall desalination process by both theoretical modeling and experimental studies. The experimental study will allow the verification of the models as well as demonstrating the feasibility of the system. The model will be used for investigating the effect of operating conditions and design parameters, as well as for the economic analysis. |
