不溶性硫磺生产中副产结晶废硫的提纯研究
|
摘要
以水洗与活性白土相结合的方法对不溶性硫磺生产中产生的结晶废硫进行提纯处理。考察了水加入量,水洗时间,活性白土加入量,吸附时间等因素对提纯硫磺质量及收率的影响,试验结果显示:当硫磺与水质量比为1∶1,水洗时间为30min,白土与硫磺质量比为0.01∶1,反应时间为60min时,所提纯的硫磺纯度大于99.9%,收率高于98%,提出后的硫磺完全可以用于不溶性硫磺的生产。
The crystallization waste sulfur produced in insoluble sulfur production is purified by a method combining water washing with activated clay. The addition amount of water,the water washing time and the adding amount of activated clay are inspected,adsorption time and other factors on the quality and yield of the purified sulfur,and the test result shows:when the mass ratio of the sulfur to the water is 1∶1,the water washing time is 30 minutes,the mass ratio of the white soil to the sulfur is 0.01∶1,and the reaction time is 60 minutes,the purity of the purified pure sulfur is greater than 99.9%,and the yield is higher than 98%.,and the prepared sulfur can be completely used for production of insoluble sulfur.
