摘要
太阳能驱动的界面蒸发(SIE)是一种环保和节能的淡水生产方法。然而,物料固有的输水能力限制了传统蒸发器在毛细管力驱动下被动供水方式下生产率的提高。在本研究中,我们提出了主动供水策略以及向下设计的蒸发器来克服限制。蒸发器是基于静电纺PVA/CuCr2O4薄膜构建的。利用注射泵调节供水量,寻求与太阳能蒸发量的最优匹配。在最佳供水量为0.04 mL min - 1时,在1.0太阳照度下,蒸发器的最大太阳蒸发速率为2.24 kg m-2h - 1。主动给水向下设计的蒸发器即使在高盐度为10 wt%的情况下也有很大的排盐潜力,有利于蒸发器的长期稳定运行。本研究建立了一种适应性供水方法,以最大化蒸发器的蒸发潜力。
Optimizing the solar evaporation performance of downward designed evaporator with active water supply strategy
Solar-driven interfacial evaporation (SIE) is an eco-friendly and energy-efficient approach to produce freshwater. However, the intrinsic water transport capacity of materials limits the improvement of productivity in the conventional evaporators working in passive water supply mode driven by capillary force. In this study, we proposed an active water supply strategy along with a downward designed evaporator to overcome the limitation. The evaporator was constructed based on an electrospun PVA/CuCr2O4 film. Water supply rate was regulated by a syringe pump to seek the optimal match with solar evaporation capacity. At the optimized water supply rate of 0.04 mL min−1, the evaporator delivered a maximum solar evaporation rate of 2.24 kg m-2h−1 under 1.0-sun illumination. The downward designed evaporator with active water supply also exhibited great potential in salt rejection even under high-salinity of 10 wt%, which facilitated long-term operational stability of the evaporator. This research established an adaptable water supply approach to maximize the evaporation potential of the evaporators.
