摘要太陽能驅動薄膜蒸餾海水淡化系統,係結合太陽能集熱設備與薄膜蒸餾之整合系統,其特點是將太陽能集熱及儲存,再間接輔助予薄膜蒸餾單元使用。太陽能驅動薄膜蒸餾之主要設備包括:(1)太陽能集熱器;(2)儲熱系統;(3)熱交換器;(4)薄膜蒸餾單元;(5)其他附屬設備,如真空幫浦等。本子題前年度探討單一薄膜蒸餾模組(DCMD, AGMD)之最適結構設計,並改變不同的薄膜蒸餾單元之各種設計及操作參數,以及降低每單位產水量之能耗。本年度將利用程序設計軟體Aspen Custom Molder (ACM),進行多個薄膜蒸餾模組(AGMD, VMD)間之流程最適化組合之求解。並探討捲式與中空纖維管模組之不同模組間的流程組合,加入真空裝置操作後,尋找最適化之設計與操作條件。最後利用子計劃一的史特靈熱電收集系統與子計畫二的儲熱系統進行熱電整合,提供真空蒸餾的電能和加熱流體的熱能,提高整體系統之熱電整合效率。本子計畫的研究目的為:(1)設計與模擬各種薄膜模組群,探討最適化模組系統組合,提高能量的使用效率及提升淡水產量;(2)建立聚焦型太陽能電熱整合,開發與設計高效能薄膜蒸餾模組系統。並整合各子計畫的研究成果,完成高效率且兼具自動控制之太陽集熱設備輔助式薄膜蒸餾程序整合系統。
The solar heat assisted membrane seawater desalination system is constructed of solar collectors and membrane distillation devices for increasing pure water productivity. The advantage of this technically and economically feasible system is designed to use the indirect solar heat to drive membrane distillation process in overcoming the unstable supply of solar radiation from sunrise to sunset. The solar heat assisted membrane seawater desalination system in the present study is consisted of (1) solar water heaters; (2) hot water storage devices; (3) heat exchangers; (4) membrane distillation units; (5) other auxiliary equipment such as direct vacuum pump. The membrane distillation systems include three different devices of direct contact membrane distillation (DCMD), Spiral-wound and hollow fiber modules. The study on DCMD and AGMD have been done on the design parameters (flow pattern, channel thickness, aspect ratio, roughness, pitch and modules in parallel or in series) and operating parameters (inlet temperature and flow rate) to obtain the maximum pure water productivity with less energy consumption in our last year project. Meanwhile, Aspen Custom Molder (ACM) software is introduced in this process design to achieve the optimal design arrangement of membrane distillation configurations (AGMD, VMD). Secondly, the three modules combinations in parallel or in series of flat-plate, spiral-wound and hollow fiber membrane distillation modules with adding vacuum operation are investigated theoretically and experimentally for finding optimal operating conditions. The purposes of this study are (1) to design and simulate alternative combinations of three modules to maximize the pure water productivity per unit energy consumption with both mathematical modeling and experimental studies; (2) to integrate all sub-project fruitful results of this overall research plan and accomplish a high performance on solar energy assisted membrane seawater desalination system.
