太阳能光热驱动界面蒸发系统的蒸发和收集性能优化
Optimization of Evaporation and Collection Performance of Solar Photothermal-Driven Interfacial Evaporation Systems
摘要
Abstract
Solar photothermal-driven interfacial evaporation represents a promising new technology for desalina-tion,attracting considerable attention.However,the development of practical devices has been hindered by challenges in large-scale design and assembly.This study focuses on the manufacturing and optimization of the arrangement of single solar evaporators.Three types of steam condensers were designed using high-transmittance polyvinyl alcohol(PVA)anti-fog film,commercial polyvinylidene(PO)film,and glass materi-als,all of which were integrated with water purification collectors to establish three solar photothermal-driven interfacial evaporation and collection systems.Additionally,multi-unit evaporation system components were optimized by setting the evaporation system angle to 60°,introducing a thermal layer for water intake,adopting an asymmetric supply layer structure on both sides(with a ratio of 1∶2),and applying a top-cover cooling strat-egy.The findings suggest that the evaporation rate of the solar interface evaporator can reach 4.88 kg/(m²·h)under a light intensity of 400 mW/cm2.Notably,when the glass material with optimal anti-fog properties was employed for collecting condensate,the system exhibited a lower water collection efficiency of 3.05 kg/(m²·h).Additionally,the implementation of the top-cover cooling strategy did not positively influence the conden-sate collection,or it failed to effectively improve the collection efficiency.The innovative structure of the solar interfacial evaporator provides significant insights for large-scale application research in seawater desalination and wastewater purification.关键词
