基于二维光热材料的界面太阳能光热蒸发系统优化
Optimization of interfacial solar photothermal evaporation system based on two-dimensional photothermal materials
摘要
Abstract
Seawater desalination is an important way to alleviate the global shortage of freshwater resources,but traditional seawater desalination technologies have problems of high cost,high energy consumption and low efficiency.The interfacial solar steam generation(ISSG)technology,which utilizes solar energy as the sole energy input,has attracted great attention due to its advantages of low cost,sustainability and high efficiency.ISSG evaporates and condenses water molecules at the gas-liquid interface through efficient photothermal conversion to obtain freshwater.This paper introduced the evolution of the structure of the interface solar absorber designed with two-dimensional photothermal materials in recent years,and focused on the analysis of the development process of film(coating)-aerogel-hydrogel(foam).It pointed out that the photothermal evaporation system based on hydrogel(foam)had the unique advantages of efficient thermal positioning,efficient photothermal conversion,efficient salt resistant deposition,rapid water delivery and water activation.On this basis,the development prospects and challenges of ISSG were summarized,and a new intelligent evaporation system with automatic adjustment of evaporation rate and steam temperature was proposed.The new strategy of interconnecting it with energy,agriculture,industry and other fields was proposed,aiming to inspire the scientific design and engineering application of solar thermal evaporation systems for large-scale solar powered clean water production from laboratories to practical applications.关键词
