Abstract

Enhancing nocturnal productivity holds promise for boosting the effectiveness of solar desalination setups. Current research concentrates on an innovative strategy: integration of Paraffin wax and Jatropha biodiesel as a composite energy storage material (CESM) to amplify distilled water output during nighttime. The composite material, comprising Jatropha biodiesel and paraffin wax in a 1:1 ratio by weight, is meticulously examined for its impact on productivity, juxtaposed against a conventional solar still (CSS). Results reveal a substantial improvement in thermal conductivity with CESM, exhibiting a noteworthy 58.33% surge compared to pure paraffin wax. Furthermore, a Solar Still with Biodiesel and Phase Change Material (SSBDPCM) is pitted against a CSS, with continuous monitoring of water and absorber temperatures alongside distillate production. The findings illustrate that SSBDPCM achieves a 16% upsurge in water temperature and a 10% elevation in absorber temperature compared to CSS. Impressively, SSBDPCM achieves a staggering 63% increase in distillate production, yielding 3.6 and 3.4 liters per square meter, in sharp contrast to CSS, which only manages 2.2 and 2.1 liters per square meter over a two-day test period.Furthermore, a comprehensive cost analysis showcases the economic superiority of SSBDPCM over CSS. SSBDPCM demonstrates a compelling 29.2% reduction in cost per liter and a significant 25.9% decrease in payback period in comparison to CSS. These compelling outcomes underscore the substantial potential of the SSBDPCM approach in delivering heightened efficiency and cost-effectiveness, paving the way for a promising advancement in solar stills.
麻疯树生物柴油与石蜡混合物储热材料的研制,以提高太阳能海水淡化系统的淡水发电能力
提高夜间生产力有望提高太阳能海水淡化装置的有效性。目前的研究集中在一种创新策略上:将石蜡和麻疯树生物柴油整合为一种复合储能材料(CESM),以提高夜间蒸馏水的产量。该复合材料由麻风树生物柴油和石蜡以1:1的重量比组成,与传统的太阳能蒸馏器(CSS)并列,仔细检查了其对生产力的影响。结果显示,与纯石蜡相比,CESM的热导率显著提高,表现出显著的58.33%的激增。此外,采用生物柴油和相变材料的太阳能蒸馏器(SSBDPCM)与CSS进行了对比,在蒸馏物生产的同时,对水和吸收器的温度进行了连续监测。研究结果表明,与CSS相比,SSBDPCM实现了16%的水温升高和10%的吸收器温度升高。令人印象深刻的是,SSBDPCM实现了惊人的63%的馏分油产量增长,每平方米产量分别为3.6和3.4升,与CSS形成鲜明对比,CSS在两天的测试期内仅管理每平方米2.2和2.1升。此外,综合成本分析显示了SSBDPCM相对于CSS的经济优势。与CSS相比,SSBDPCM每升成本显著降低29.2%,回收期显著缩短25.9%。这些令人信服的结果强调了SSBDPCM方法在提高效率和成本效益方面的巨大潜力,为太阳能蒸馏器的发展铺平了道路。
