尕斯库勒盐湖卤水模拟自然蒸发试验研究

摘要

尕斯库勒湖是柴达木盆地众盐湖中较为典型的硫酸镁亚型盐湖.利用相图规律对该盐湖卤水自然蒸发的结晶路线进行了分析,并通过室内模拟自然蒸发试验进行了验证,最终获得了在自然条件下蒸发卤水分步结晶不同盐类的工艺路线,可为该盐湖资源综合利用提供依据.%Gas Hure salt lake is one of the relatively typical magnesium sulfate subtype in Qaidam basin. In the present paper,the crystalization route of the natural evaporation of Gas Hure salt lake using the law of phase diagram was analysed and natural evaporation process was checked by indoor simulation. Trie processing route of different salts that crystallized step by step form brine during natural evaporation were obtained/derived, which provided the basis for comprehensive utilization of brine in Gas Hure salt lake.
