海水淡化浓盐水太阳能加热性能研究

实验采用真空管太阳能集热器系统,研究了太阳能对6波美度海水淡化浓盐水的加热性能。实验采用了自动采集与监测系统,主要考察了太阳能辐照度、环境温度、湿度、风速等四个气象因子以及进水流量、温度单因素对浓盐水太阳能集热性能的影响。研究结果表明,浓盐水的集热速率与太阳辐照强度关系最为密切,其他因子对浓盐水太阳能集热性能无显著影响。

Heating Performance of Seawater Desalination Brine by Solar Energy

Solar heating process was studied with system of evacuated solar tube collector. The heated media was brine which has some compositions with brine obtained from seawater desalination. Automatic signal collection system was used for measuring the parameters in the system including solar irradiance,wind temperature,humidity,wind speed and flow rate and temperature of brine. The factors which affected heating performance of seawater desalination brine were studied. Results showed that solar irradiance was the most closely related to collector rate of brine and other factors had little effect on heating performance of brine.
