淡化浓海水自然蒸发速度影响规律研究

The Effect of Natural Evaporation Factors on Evaporation Rate of Concentrated Seawater

针对当前气象因素(辐照强度、风速、空气温度和相对湿度)与卤水因素(卤水温度)作用于卤水蒸发速率定量研究的数据缺乏等问题,本研究采用室内蒸发模拟系统及信号采集系统相结合的实验方法,以气候条件为依据,进行了淡化浓海水自然蒸发的模拟实验。采用统计学中的分析方法,对实验数据进行分析。结果表明卤水蒸发速率随辐照度、风速的增加呈线性增加以及相对湿度的增加呈线性减小,随卤水温度和环境温度呈2次曲线增加。

Due to lack of the data of the effect of meteorological factors（irradiation intensity, wind speed, air temperature and relative humidity） and brine factor（brine temperature） on the evaporation rate, the simulation experiments of concentrated seawater natural evaporation were carried out by designing and constructing indoor simulation system, and signal acquisition system to simulate the natural evaporation process based on the real climatic conditions in this study. With the statistical analysis method, the qualitative relationship and fitted equation between the single factor and the evaporation rate were obtained, It can be concluded that the brine evaporation rate has a linear increase with the increasing of irradiation intensity and wind speed, on the contrary, the brine evaporation rate has a linear decrease with the increasing of relative humidity, while it have a quadratic relationship with the increasing of brine temperature and environment temperature.
