摘要:

淡水資源短缺是全球面臨的重大問(wèn)題，利用太陽(yáng)能界面蒸發(fā)技術(shù)進(jìn)行海水淡化是近年來(lái)發(fā)展的一種綠色解決方案。蒸發(fā)速率是太陽(yáng)能界面蒸發(fā)技術(shù)重要的衡量指標(biāo)，由于自然界太陽(yáng)光的強(qiáng)度是一定的，蒸發(fā)速率主要受限于水的蒸發(fā)潛熱。太陽(yáng)能蒸發(fā)器是太陽(yáng)能界面蒸發(fā)系統(tǒng)的核心元件，利用太陽(yáng)能蒸發(fā)器材料的化學(xué)基團(tuán)和物理結(jié)構(gòu)降低水的蒸發(fā)潛熱成為提升太陽(yáng)能界面蒸發(fā)速率的重要途徑。首先對(duì)太陽(yáng)能界面蒸發(fā)技術(shù)和太陽(yáng)能蒸發(fā)器進(jìn)行簡(jiǎn)要介紹，然后對(duì)可降低水潛熱的太陽(yáng)能蒸發(fā)器的研究應(yīng)用進(jìn)行詳細(xì)總結(jié)，重點(diǎn)對(duì)太陽(yáng)能蒸發(fā)器降低水的蒸發(fā)潛熱的機(jī)制進(jìn)行分析歸納，最后對(duì)可降低水潛熱的太陽(yáng)能蒸發(fā)器的發(fā)展進(jìn)行展望，以期為可降低水潛熱的太陽(yáng)能蒸發(fā)器的后續(xù)研發(fā)提供參考，進(jìn)一步提升太陽(yáng)能界面蒸發(fā)技術(shù)在海水淡化領(lǐng)域的競(jìng)爭(zhēng)力。

Abstract:

The shortage of fresh water resources is a major problem facing the world. Seawater desalination using the technology of solar-driven interfacial evaporation is a green solution developed in recent years. Evaporation rate is an important index of solar-driven interfacial evaporation. Because the intensity of natural sunlight is constant, evaporation rate is mainly limited by the latent heat of water evaporation. Solar evaporator is the core component of solar interfacial evaporation system. Reducing the latent heat of water evaporation through the chemical groups and physical structure modulations of solar evaporator materials turns into an important way to improve the solar interfacial evaporation rate. In this review, the technology of solar-driven interfacial evaporation and the knowledge of solar evaporator were briefly introduced firstly. And then, solar evaporators which can reduce the latent heat of water evaporation were presented in detail. In addition, the mechanism of reducing the latent heat of water evaporation with solar evaporators was analyzed and summarized. The prospect and future challenges of solar evaporators with the ability of reducing latent heat were discussed finally, so as to provide reference for the follow�瞮p research and development of solar evaporators with the ability of reducing latent heat, and further enhance the competitiveness of solar-driven interfacial evaporation in the field of seawater desalination.
