摘要

甘蔗（Saccharum officinarum L. (SO)）是一种广泛种植的热带作物，为生产二氧化钛纳米粒子（TiO2）提供了可持续的原料来源。本研究探讨了这些纳米粒子在提高单池太阳能蒸馏器（SBD）效率方面的潜力，单池太阳能蒸馏器是一种利用太阳能净化水的设备。研究人员在印度维贾亚瓦达建造并测试了一种新颖的单流域太阳能蒸馏器设计，该设计具有独特的流域形状和装有 TiO2 纳米流体（ASTSO）的铝银瓶（AS）。铝银瓶呈碗状排列并充满纳米流体，大大提高了吸热能力。此外，与传统的太阳能蒸馏器（CSS）相比，SBD 独特的盆地形状使蒸发表面积增加了 26%。SBD 的产水量显著增加，夏季产量为 8.437 公斤/平方米/天，冬季产量为 8.087 公斤/平方米/天。这相当于夏季日效率（ASTSO）为 58.73%，冬季为 47.52%，与传统太阳能蒸馏器相比有了大幅提高。性能的提高归功于纳米流体热性能的改善，它加速了蒸发和冷凝过程。纳米流体更高的导热性和吸热能力也有助于提高产水量。对 SBD 和 CSS 进行的经济比较分析表明，在未来十年内，这两种系统的蒸馏水预计成本将分别稳定在 1.93 卢比/千克和 2.19 卢比/千克。这项研究为提高太阳能蒸馏器的效率和生产率提供了一种前景广阔的方法，为水净化提供了一种可持续的、具有成本效益的解决方案。未来的研究将侧重于优化纳米流体浓度、探索其他纳米材料，以及将先进的太阳能蒸馏器与可再生能源技术相结合，以开发可持续的水净化系统。

Optimizing solar still performance: A study of TiO2 nanofluid derived from Saccharum officinarum L.

Sugarcane (Saccharum officinarum L. (SO)), a widely cultivated tropical crop, provides a sustainable source of raw material for producing TiO₂ nanoparticles (T). This study investigates the potential of these nanoparticles to improve the efficiency of Single Basin Solar Distiller (SBD), which is devices that harness solar energy to purify water. A novel SBD design featuring a unique basin shape and aluminum silver bottles (AS) filled with TiO₂ nanofluid (ASTSO) was constructed and tested in Vijayawada, India. The AS arranged in a bowl-like configuration and filled with nanofluid, significantly enhance heat absorption. Moreover, the SBD’s unique basin shape increases the evaporative surface area by 26 % compared to conventional solar stills (CSS). The SBD demonstrated a notable increase in water production, achieving yields of 8.437 kg/m2/day in summer and 8.087 kg/m2/day in winter. This corresponds to a daily efficiency (ASTSO) of 58.73 % in summer and 47.52 % in winter, representing a substantial improvement over traditional solar stills. The enhanced performance is attributed to the improved thermal properties of the nanofluid, which accelerate the evaporation and condensation processes. The nanofluids higher thermal conductivity and heat absorption capacity contribute to the increased water production. A comparative economic analysis of the SBD and CSS was conducted, revealing that the projected cost of distilled water from both systems is expected to remain stable at Rs 1.93/kg and Rs 2.19/kg, respectively, over the next decade. This research presents a promising approach to enhance the efficiency and productivity of solar stills, providing a sustainable and cost-effective solution for water purification. Future research will focus on optimizing nanofluid concentrations, exploring other nanomaterials, and integrating advanced solar stills with renewable energy technologies to develop sustainable water purification systems.

期刊介绍： Separation and Purification Technology is a premier journal committed to sharing innovative methods for separation and purification in chemical and environmental engineering, encompassing both homogeneous solutions and heterogeneous mixtures. Our scope includes the separation and/or purification of liquids, vapors, and gases, as well as carbon capture and separation techniques. However, it's important to note that methods solely intended for analytical purposes are not within the scope of the journal. Additionally, disciplines such as soil science, polymer science, and metallurgy fall outside the purview of Separation and Purification Technology. Join us in advancing the field of separation and purification methods for sustainable solutions in chemical and environmental engineering.
