将均匀曝气与超声雾化2种技术结合,设计研制出一种新型的增湿除湿式太阳能海水淡化系统,并研究了太阳光辐射照度与温度的关系以及超声雾化、液位、气体流量对产水速度的影响。结果表明,太阳光辐射照度与温度呈正相关,超声雾化对产水量有显著影响,在全天累计曝辐射量为22.96 MJ/(m2·d),液位为20 cm、气体体积流量为15.4m3/h的情况下,系统累计产水量为20 L/d,热效率为0.56,单位面积产水量为5.6 L/(m2·d),是前人成果的1.2~2.6倍,产水性能提升明显。
Combining uniform aeration with ultrasonic atomization, a new type of humidification and dehumidification solar desalination system was designed and developed. The relationship between solar radiation illuminance and temperature as well as ultrasonic atomization, liquid level and gas flow rate Impact on water production rate. The results showed that there was a positive correlation between solar radiation irradiance and temperature, and ultrasonic atomization had a significant effect on water production. The cumulative radiation exposure was 22.96 MJ / (m2 · d), the liquid level was 20 cm and gas volume flow was 15.4 m3 / h, the cumulative water yield of the system is 20 L / d, the thermal efficiency is 0.56, and the water yield per unit area is 5.6 L / (m2 · d) .
