300 kt/a湿法磷酸装置生产过程中可溶性杂质迁移规律研究
|
摘要
以云南云天化股份有限公司300 kt/a大型湿法磷酸生产装置为对象,对装置全流程各工序物料或产物进行取样,分析研究主要可溶性杂质在磷矿浆、稀/浓磷酸、氟吸收水相、过滤洗水、工艺循环水、磷石膏再浆水、磷石膏渣场多种回水、各种结垢物、各种沉渣、磷石膏等多种工艺性物料、产物或副产物之间的迁移规律,研究结果对大型湿法磷酸装置生产工艺改进、水平衡优化、节能减排、资源回收利用等具有参考价值。
Taking a large-scale WPA plant of Yunnan Yuntianhua Co., Ltd. as a target, materials or products are sampled to analyze and study the migration regularity of main soluble impurities in phosphate slurry, dilute/rich phosphoric acid, fluorine absorption water phase, filtration wash water, process circulation water, phosphogypsum slurry water, phosphogypsum residue field back water, various scaling agents, various slags, phosphogypsum and other process materials, products. The research result has reference value for the improvement of the production process, water balance optimization, energy conservation and emission reduction, resource recycling and utilization of large-scale WPA plant.
