Method for removing potassium chloride in bricks used for cement kiln
The invention discloses a method for removing potassium chloride in a used brick of a cement kiln, the implementation process of the method comprises the steps of pulverizing, preparing a composite acid solution, soaking, filtering, drying and the like, and the highest removal rate of the potassium chloride can reach 99.856%. The adopted reagent raw materials are low in price, the treatment process is simple, the potassium chloride in the used brick of the cement kiln can be removed only through soaking and filtering, the potassium chloride removal efficiency is high, the treatment cost is low, and industrial application is easy to achieve. The content of potassium chloride in the finally obtained regenerated complex-phase magnesia fine powder is only 0.005%, and the regenerated complex-phase magnesia fine powder can be used as a production raw material of building materials or refractory materials, so that sustainable utilization of non-renewable resource magnesia is realized, the problem of environmental pollution caused by stacking of bricks used in a cement kiln is effectively solved, and remarkable economic and social benefits can be generated.
本发明公开了一种水泥窑用后砖中氯化钾的去除方法，该方法的实施过程包括制粉、配置复合酸溶液、浸泡、过滤和干燥等步骤，氯化钾的去除率最高可达99.856％。本发明采用的试剂原料价格低廉，处理工艺简单，只需要通过浸泡过滤即可实现水泥窑用后砖中氯化钾的去除，氯化钾去除效率高，处理成本低，易于实现工业化应用。最终得到的再生复相镁砂细粉中氯化钾含量仅为0.005％，可作为建材或耐火材料的生产原料，实现了不可再生资源镁砂的可持续利用，有效解决了水泥窑用后砖堆放污染环境的问题，可产生显著的经济和社会效益。
