Device and method for preparing II-type anhydrite from suspended phosphogypsum
The invention provides a device and a method for preparing II-type anhydrous gypsum from suspended phosphogypsum. The device comprises a drying system, a preheating calcining system, a cooling collecting system and a pipeline system. According to the device disclosed by the invention, the processes of drying, preheating, calcining, cooling and the like are combined through a pipeline system, so that gradient utilization of heat of the system is realized, energy is saved, consumption is reduced, soluble phosphorus and fluorine in phosphogypsum are effectively removed, and the phosphogypsum is accurately converted into excellent II-type anhydrous gypsum; the method follows the concepts of sustainable development and circular economy, resource utilization of phosphogypsum is achieved to the maximum extent, energy is fully utilized, high-temperature waste gas emission is avoided, the production cost is greatly reduced, and industrial large-scale production can be achieved.
本发明提供一种悬浮式磷石膏制备Ⅱ型无水石膏的装置及方法，本发明装置包括干燥系统、预热煅烧系统、冷却收集系统及管路系统。本发明装置通过管路系统将干燥、预热、煅烧、冷却等工艺相结合，实现系统热量梯次利用、节能降耗，且有效去除磷石膏中可溶性磷、氟，将磷石膏精准转化为优异的Ⅱ型无水石膏；本发明遵循可持续发展和循环经济的理念，最大限度实现磷石膏资源化利用，充分利用能源，无高温废气排放，生产成本大幅度降低，可实现工业化大规模生产。
