摘要
针对目前钛白废酸回收利用工艺存在的不足,提出了喷雾浓缩钛白废酸的技术方案,该技术方案具有传热效率高、设备费用低和不易堵塞的优点。根据喷雾干燥原理,探索了喷雾浓缩原理,为喷雾浓缩原理提供理论依据。研制出的喷雾浓缩装置可以一级将钛白废酸由质量分数为20%浓缩至80%以上,浓缩效果明显,具有较好的推广应用价值。
According to the deficiency of recycling technology for waste acid from titanium white production,a technical scheme of spray concentration of titanium white waste acid was proposed.This scheme had the advantages,such as high heat transfer efficiency,low cost of equipment,and seldom blockage.Based on the principle of spray drying,the principle of spray concentration had been explored,which provided theoretical basis for spray concentration.Spray concentration equipment had been developed,by which the mass fraction of waste acid could be concentrated to more than 80% from 20% by one-step concentration.Therefore,the spray concentration equipment had very good concentrated effect and application value.
