论文摘要
太阳能仍然是一种方便的离网装置，可用于淡化，可以为家庭，船只，岛屿等提供淡水。常规的倾斜太阳能静止（ISS）遭受低效率和低生产率的损害。为了提高太阳能的性能，提出了平坦的太阳能静止（FSS），该太阳能（FSS）具有类似于太阳能电池的工作原理。 FSS中的冷凝水是由附着在超血液玻璃盖下的毛细血管网格而不是重力收集的。因此，FSS避免了倾斜的结构，并且比ISS更紧凑。 FSS的每日生产率可达4.3 kg/m2。理论分析表明，通过紧凑结构在FSS中增强的传质是高性能的重要因素。更有趣的是，FSS也很容易扩展到更多的阶段，以进行潜热恢复。结果表明，双阶段FSS的每日生产率可达到7 kg/m2，这比传统太阳能静止高得多。 FSS在设计和优化太阳能静止状态时铺平了一种新的方式。
Solar still is a convenient off-grid device for desalination, which can provide fresh water for families, ships, islands and so on. The conventional inclined solar still (ISS) suffers from low efficiency and low productivity. To improve the performance of solar still, a flat solar still (FSS) is proposed, which has a working principle similar to the solar cell. The condensate water in FSS is collected by the capillary grid attached under the ultra-hydrophilic glass cover, instead of by gravity. Therefore, FSS avoids the inclined structure and is much more compact than ISS. The daily productivity of FSS reaches up to 4.3 kg/m2. Theoretical analysis shows that the enhanced mass transfer in FSS by the compact structure is an important factor for high performance. More interestingly, FSS can also be easily extended to more stage for latent heat recovery. The results show that the daily productivity of a double-stage FSS reaches up to 7 kg/m2, which is much higher than the conventional solar still. FSS paves a new way in designing and optimizing of solar still.
