摘 要:本研究旨在优化硫酸法钛白生产中的酸解过程,以提高酸解率和产品质量。通过实验分析了酸矿比、硫酸浓度、蒸汽加入方式和加量、压缩空气使用等因素对酸解率的影响。结果表明:酸矿比2.10、硫酸体积分数82%、连续蒸汽加入方式且每吨钛矿粉加量为1.5 kg、压缩空气压力0.5 MPa,为硫酸法钛白粉生产最优条件,此时,酸解率最高达到97.64%,该研究结果可为硫酸法钛白粉工业生产提供优化参考。This study aims to optimize the acid hydrolysis process in the production of titanium dioxide by sulfuric acid method,in order to improve the acid hydrolysis rate and product quality.The influence of factors such as acid ore ratio,sulfuric acid concentration,steam addition method and amount,and compressed air usage on the acid hydrolysis rate was analyzed through experiments.The results showed that the optimal conditions for the production of titanium dioxide by sulfuric acid method were acid to mineral ratio of 2.10,sulfuric acid volume fraction of 82%,continuous steam addition method with a dosage of 1.5 kg per ton of titanium ore powder,and compressed air pressure of 0.5 MPa.At this time,the highest acid hydrolysis rate reached 97.64%.This research result can provide optimization reference for the industrial production of titanium dioxide by sulfuric acid method.
