摘要
设计研制了一种光热光伏耦合式小型太阳能海水淡化装置,通过光热单元来加热海水实现蒸发,通过光伏单元提供系统运行所需电能,并通过曝气装置提高蒸发效率和产水量。研究了淡水产水量与太阳辐照强度、蒸发温度、曝气之间的关系。结果表明,太阳辐照强度与蒸发温度成正相关,温度和曝气对产水量有显著影响,在太阳累计辐照量为22.58 MJ/(m^2·d)的情况下,该装置一天内的产水量可达5.35 kg/(m^2·d),性能系数达到0.545。
This paper proposes a photothermal and photovoltaic coupling of small solar desalination device. Heating through the photothermal unit to achieve evaporation of seawater, providing the required power of system by photovoltaic cells, and by aeration device to improve efficiency and productivity of water evaporation. Experimental study on the relationship between solar radiation, evaporation temperature, exposure and water production. Experimental results show that solar radiation intensity is positively correlated with the evaporation temperature. The temperature and aeration have a significant effect on water yield. Under the cumulative radiation exposure of the day 22.58 MJ/（m^2·d）, the day cumulative production capacity of the device is 5.35 kg/（m^2·d） and performance coefficient is 0.545.
