The conventional sea water desalination technologies are not yet adopted worldwide, especially in the third world countries due to their high capital cost as well as large energy requirement. To solve this issue in a sustainable way an interfacial solar water evaporation device is designed and proposed in this article using the branches of Prunus serrulata (PB). The PB has abundant microchannels and shows excellent photothermal conversion capability after carbonization. Moreover, the easy access to raw materials and the facile fabrication process makes the solar water evaporating device very cost effective for seawater desalination application. Experiments show that in the presence of the fabricated evaporator the evaporation rate of water can reach 3.5 kg m h under 1 sun, which is superior to many similar experimental devices. In addition, its advantages, such as effective sewage purification capability, low cost, and environmental friendliness, make this evaporator highly competitive in the extensive promotion of this technology and can be considered as a new sustainable solution for seawater desalination with great application potential and prospects.
传统的海水淡化技术尚未在全球范围内得到广泛应用,尤其是在第三世界国家,因为其资本成本高且能源需求大。为了以可持续的方式解决这个问题,本文设计并提出了一种利用樱花树枝(PB)的界面太阳能水蒸发装置。PB具有丰富的微通道,碳化后表现出优异的光热转换能力。此外,原材料易于获取且制造过程简便,使得该太阳能水蒸发装置在海水淡化应用中具有很高的成本效益。实验表明,在有制造的蒸发器存在的情况下,水的蒸发速率在1个太阳光照下可达3.5 kg m h,优于许多类似的实验装置。此外,其有效污水净化能力、低成本和环境友好等优点,使得该蒸发器在该技术的广泛推广中具有高度竞争力,可被视为一种具有巨大应用潜力和前景的新型可持续海水淡化解决方案。
