染色技术对盐湖卤水蒸发效率的影响

Effect of Dyeing Technology on Brine Evaporation Efficiency

盐湖自然条件下晒制成合格的卤水需要的时间与盐湖工业生产效率有着密切的联系,提高晒制光卤石原矿的效率缩短晒制时间将会提高生产效益和经济效益。当前盐湖卤水主要是在自然条件下进行晒制和蒸发,因此提出采用某类物质对卤水进行染色从而提高其蒸发速率。文章研究了自然光颜色、有机化合物以及表面活性剂对盐湖蒸发速率的影响。实验结果表明:绿色染料对卤水蒸发速率与其它颜色染料相比具有巨大的优势,蒸发速率达到了0.439 kg/m^(2)·h。有机化合物中乙醇对卤水蒸发速率影响最大,在乙醇加入后速率达到了0.175 kg/m^(2)·h,蒸发速率增加了29.6%。而表面活性剂中十二烷基磺酸钠和十二烷基苯磺酸钠的加入也促进了卤水蒸发,蒸发速率分别为0.349 kg/m^(2)·h和0.315 kg/m^(2)·h,蒸发速率增加了23.7%和11.7%。通过研究染色技术对卤水蒸发效率的影响为提高生产效率和科学研究提供依据。

The time required for drying qualified brine under natural conditions in salt lakes is closely related to the industrial production efficiency of salt lake.Therefore,if the efficiency of drying carnallite ore is improved and the drying time is shortened,the production efficiency and economic benefits will be improved.At present,the salt lake brine is mainly dried and evaporated under natural conditions.Therefore,it is proposed to use certain substances to dye the brine to increase its evaporation rate.The effects of natural light color,organic compounds and surfactants on the evaporation rate of salt lake were studied.The experimental results showed that green dyes had great advantages over other color dyes in the evaporation rate of brine,and the evaporation rate reached 0.439 kg/m^(2)·h.Among the organic compounds,ethanol has the greatest influence on the evaporation rate of brine.After the addition of ethanol,the rate reaches 0.175 kg/m^(2)·h and the evaporation rate increases by 29.6%.The addition of sodium dodecyl sulfonate and sodium dodecyl benzene sulfonate in the surfactant also promoted the evaporation of brine.The evaporation rates were 0.349 kg/m^(2)·h and 0.315 kg/m^(2)·h,respectively.The evaporation rate increased by 23.7%and 11.7%.By studying the effect of dyeing technology on brine evaporation efficiency,it provided a basis for improving production efficiency and scientific research.
