盐湖老卤蒸发气候条件研究与蒸发模型建立

通过开展环境气候条件实验研究,揭示环境气候主要参数大气湿度和老卤蒸发速度之间的关系,建立了老卤蒸发模型,并利用模型推算出老卤自然蒸发的大气相对湿度极限值为33.2%。实验证明蒸发环境大气相对湿度小于该值时老卤将会自然蒸发,大于该值时不但不蒸发,还将倒吸空气中的水分。利用本研究蒸发数学模型,可以预测盐湖气候季节变化过程中老卤蒸发情况,为合理设计老卤蒸发方案提供科学依据。

Evaporation conditions of the saline bittern and evaporation modeling

The experimental study of the environmental climate was conducted to reveal the relationship between the bittern evaporation rate and the environmental air relative humidity,which was a chief parameter of the climate and a bittern evaporation model was built.On the basis of the model,the relative humidity limit(33.2%) of the bittern naturally evaporation was figured out.The experiment showed that the bittern would naturally evaporate when the environmental relative humidity was higher than the figure and it would not naturally evaporate when environmental relative humidity was lower than the figure.Contrarily,it would absorb moisture in air.By using the model,the situation of the bittern evaporation could be forecasted in the process of climate and seasonal change in saline lake,which could provide a scientific basis for reasonably designing bitten evaporation projects.
