Abstract

This work aims to improve the productivity and efficiency of conical solar stills by introducing an innovative design that implements dual-tray basins combined with truncated cone external reflectors within the water basins. In this design, a secondary water basin with a smaller diameter is added alongside the primary distillation basin. In addition, truncated cone reflectors were used around the solar still to increase the concentration of solar radiation on the expanded evaporative surface. Three conical distillers were constructed and tested to evaluate the performance of the proposed designs. The first was a traditional conical distiller (TCSD) without any modifications, the second used dual-tray basins (TSD-DTB), and the third used dual-tray basins combined with truncated cone external reflectors (TSD-DTB&TCR. The findings indicated that the use of TSD-DTB and TSD-DTB&TCR increased water production by 29.31 % and 73.15 %, respectively. Additionally, the productivity of TSD-DTB&TCR was 33.91 % higher than that of TSD-DTB. Furthermore, the exergy efficiency of TSD-DTB and TSD-DTB&TCR improved by 62.83 % and 180.73 %, respectively. The yield cost of TSD-DTB&TCR decreased by 20.95 % and 45.23 % compared to TSD-DTB and TCSD respectively. The payback time of TSD-DTB&TCR was reduced by 10.01 % and 28.94 % compared with TSD-DTB and TCSD, respectively. Finally, the TSD-DTB&TCR can generate $37.27 in carbon credits, which is 78.27 % and 35.00 % higher than those of TCSD and TSD-DTB, respectively.

锥形太阳蒸馏器性能的e评价与优化——创新双盘盆与截形锥形外反射器组合的研究

这项工作旨在通过引入一种创新的设计，实现双托盘盆与截锥形外部反射器在盆内相结合，提高锥形太阳能蒸馏器的生产力和效率。在此设计中，在一次蒸馏池旁边增加了一个直径较小的二次蒸馏池。此外，在太阳蒸馏器周围使用截锥反射器，以增加太阳辐射在膨胀蒸发表面上的浓度。建造了三个锥形蒸馏器并进行了测试，以评估所提出设计的性能。第一个是未经任何修改的传统锥形蒸馏器（TCSD），第二个是双塔板盆地（TSD-DTB），第三个是双塔板盆地与截断锥外反射器（tsd - dtbtcr）相结合。结果表明，TSD-DTB和TSD-DTB&；TCR的使用分别提高了29.31%和73.15%的产水量。此外，TCR的产率比TSD-DTB高33.91%。此外，TSD-DTB和tsd - dtb&tcr的火用效率分别提高了62.83%和180.73%。与TSD-DTB和TCSD相比，TCR的产率成本分别降低了20.95%和45.23%。与TSD-DTB和TCSD相比，TCR的投资回收期分别缩短了10.01%和28.94%。最后，tsd - dtbtcr可产生37.27美元的碳信用额，分别比TCSD和TSD-DTB高78.27%和35.00%。
