摘要
本文以铝生产过程中产生的固废物赤泥为研究对象,进行赤泥干燥实验研究,考察干燥时间、物料量、温度对赤泥脱水率的影响,研究结果表明:在一定的条件下赤泥脱水率与温度成正比,与物料量成反比。实验控制物料量为40g,干燥时间为240min,温度为100℃,赤泥脱水率可达99.40%。实验研究对环境保护、赤泥中有价金属资源综合利用具有实验指导意义。
In this paper,the solid waste red mud produced in the process of aluminum production is taken as the research object,and the drying experiment of red mud is conducted to investigate the effects of drying time,material quantity and temperature on the dehydration rate of red mud.The results show that:under certain conditions,the dehydration rate of red mud is directly proportional to temperature and inversely proportional to material quantity.The dehydration rate of red mud can reach 99.40%after 40 g material,240 min drying time and 100℃drying temperature.The experimental study has guiding significance for environmental protection and comprehensive utilization of valuable metal resources in red mud.
