Phosphorite calcining system and phosphorite calcining tail gas treatment method thereof
The invention provides a phosphorite calcining system which comprises a calcining kiln and a calcining gas treatment subsystem, the calcining gas treatment subsystem comprises a cyclone separator, a dust removal bag, a washing tower and a solid-liquid mixing tank, and the cyclone separator is connected with the calcining kiln and used for separating calcining tail gas to obtain first powder and a first gas-solid mixture; the first powder is input into a solid-liquid mixing tank, the first gas-solid mixture is input into a dust removal bag to be separated to obtain second powder and a second gas-solid mixture, the second powder is input into the solid-liquid mixing tank, the second gas-solid mixture is input into a washing tower to obtain washing liquid and washing gas, and the washing liquid is input into the solid-liquid mixing tank. The invention further provides a method for treating phosphorite calcination tail gas by applying the phosphorite calcination system. According to the phosphorite calcination system, the utilization rate of powder in phosphorite calcination tail gas is increased, waste emission is reduced, the production cost is reduced, and resource utilization of materials is achieved.
本发明提供了一种磷矿煅烧系统，包括煅烧窑和煅烧气体处理子系统，煅烧气体处理子系统包括旋风分离器、除尘袋、洗涤塔和固液混合罐，旋风分离器与煅烧窑连接，用于将煅烧尾气分离得到的第一粉体和第一气固混合物，第一粉体输入到固液混合罐，第一气固混合物输入到除尘袋分离得到第二粉体和第二气固混合物，第二粉体输入到固液混合罐，第二气固混合物输入到洗涤塔得到洗涤液和洗涤气体，洗涤液输入到固液混合罐。本发明还提供一种应用该磷矿煅烧系统进行磷矿煅烧尾气处理的方法。本发明的磷矿煅烧系统提高了磷矿煅烧尾气中的粉体利用率，既减少了废弃物的排放，又节约了生产成本，实现物料的资源化利用。
