提出了一种提高太阳能蒸发效率的新策略，探索了容积式太阳能蒸发装置在海水淡化和废水处理中的实际应用。基于纳米流体的容积式太阳能蒸发系统可以有效地提高太阳辐射的吸收率。然而，太阳能的蒸发效率相对较低。有必要研究这种限制的基本原理，并找到一种新的策略来提高太阳蒸发效率。本文首次设计了一种新型的以碳化钨纳米流体为工质的装置，以减少散热损失，提高纳米流体的稳定性，避免纳米颗粒的污染。结果表明，当碳化钨纳米流体的质量分数为0.3wt%时，在1 cm的穿透距离内可获得99%的入射光能。光热转换效率为97.7%。这种新型装置的蒸发率为1.235千克/米−2小时−1，在1个太阳的照射下达到了74.9%的太阳蒸发效率。在海水淡化和废水处理中的应用表明，海水离子截留率高于99.99%，重金属离子含量显著低于世界卫生组织饮用水标准。
The current work proposes a new strategy to improve solar evaporation efficiency and explore the real applications of volumetric solar evaporation device in desalination and wastewater treatment. Nanofluid based volumetric solar evaporation system is efficient to enhance the absorbance of solar irradiation. However, the solar evaporation efficiencies are relatively low. There is a need to investigate the fundamentals of the limitation and find a new strategy to improve the solar evaporation efficiency. In this paper, a novel device containing tungsten carbide nanofluids as work fluids is designed for the first time to reduce heat loss towards the bulk water, improve the stability of nanofluids, and avoid contamination of nanoparticles. The results show that tungsten carbide nanofluids of 0.3 wt% can harvest 99% of the incident solar energy within 1 cm penetration distance. The photothermal conversion efficiency is 97.7%. The novel device gives an evaporation rate of 1.235 kg m−2h−1and reached solar evaporation efficiency of 74.9% under 1-sun irradiation. The applications in desalination and wastewater treatment show that the ion rejection rate of seawater is higher than 99.99%, and the content of heavy metal ion is significantly lower than that in the World Health Organization drinking-water standard.
