摘要

水资源短缺和不断增长的能源需求需要可持续的淡水生产技术。太阳能海水淡化是一个很有前途的解决方案，尽管它的性能受到低蒸发和冷凝率的限制。在此背景下，首次实验研究了在太阳能蒸馏器内利用黑色头发作为一种环保的废亲水性光热材料，以提高其蒸发和水输送速率。改进后的蒸馏器还集成了铜片，以增强蒸馏器内部的热特性。此外，还对改进后的蒸馏器进行了冷却水外冷凝影响下的试验。采用综合6E分析（能源、能源、经济、消耗-经济、消耗-环境和消耗-环境经济评价）对四种配置进行了实验测试和比较，分别是传统太阳能蒸馏器、黑头-改良、黑头-铜片、黑头-外部冷凝器以及两种材料的外部冷凝器。结果表明，采用这两种材料和外置冷凝器的改性蒸馏器在日淡水产量和能源效率方面取得了最高的性能，分别提高了103.1%和104.35%。然而，在没有外部冷凝器的情况下，用黑毛和铜片改造的蒸馏器的火用效率和成本分别提高了93.5%和34.1%，并具有更高的环保性能。总之，这些结果表明，将廉价的废料与热管理系统结合起来，以增加太阳能脱盐，实现可持续和具有成本效益的淡水生产是有希望的。

Black hair and copper chips as waste-derived modifiers to improve solar desalination performance: A comprehensive 6E analysis

Water scarcity and rising energy demands call for sustainable freshwater production technologies. Solar desalination is a promising solution, though its performance is limited by low evaporation and condensation rates. In this context, the utilization of black hair as an eco-friendly waste hydrophilic photothermal material inside a solar still in order to enhance its evaporation and water transport rates was experimentally investigated for the first time. This modified still was also integrated with copper chips to enhance thermal characteristics inside the still. Additionally, the modified stills were also tested under the influence of external condensation using cool water. Four configurations, conventional solar still, black hair-modified, black hair with copper chips, black hair with an external condenser, and both materials with the external condenser, were experimentally tested and compared using a comprehensive 6E analysis (energy, exergy, economic, exergo-economic, exergo-environmental, and exergo-enviro-economic evaluations). The results indicate that the modified still, utilizing both materials with the external condenser, achieved the highest performance in daily freshwater yield and energy efficiency, with improvements of 103.1 % and 104.35 %, respectively. Yet, without the external condenser, the still modified with black hair and copper chips attained the maximum augmentation of the exergy efficiency and cost reduction by 93.5 % and 34.1 %, respectively, with higher environmental performance as well. In summary, the outcomes illustrate the promise of combining inexpensive waste materials with thermal management systems for augmenting solar desalination to achieve sustainable and cost-effective freshwater production.

期刊介绍： Thermal Science and Engineering Progress (TSEP) publishes original, high-quality research articles that span activities ranging from fundamental scientific research and discussion of the more controversial thermodynamic theories, to developments in thermal engineering that are in many instances examples of the way scientists and engineers are addressing the challenges facing a growing population – smart cities and global warming – maximising thermodynamic efficiencies and minimising all heat losses. It is intended that these will be of current relevance and interest to industry, academia and other practitioners. It is evident that many specialised journals in thermal and, to some extent, in fluid disciplines tend to focus on topics that can be classified as fundamental in nature, or are ‘applied’ and near-market. Thermal Science and Engineering Progress will bridge the gap between these two areas, allowing authors to make an easy choice, should they or a journal editor feel that their papers are ‘out of scope’ when considering other journals. The range of topics covered by Thermal Science and Engineering Progress addresses the rapid rate of development being made in thermal transfer processes as they affect traditional fields, and important growth in the topical research areas of aerospace, thermal biological and medical systems, electronics and nano-technologies, renewable energy systems, food production (including agriculture), and the need to minimise man-made thermal impacts on climate change. Review articles on appropriate topics for TSEP are encouraged, although until TSEP is fully established, these will be limited in number. Before submitting such articles, please contact one of the Editors, or a member of the Editorial Advisory Board with an outline of your proposal and your expertise in the area of your review.
