Production method and production system of low-free-water dihydrate phosphogypsum
The invention discloses a production method and a production system of low-free-water dihydrate phosphogypsum, and the method comprises the following steps: washing and filtering the dihydrate phosphogypsum, feeding the dihydrate phosphogypsum into a sealing cover, blowing the dihydrate phosphogypsum with steam, and then sucking the dihydrate phosphogypsum to be dry, so that the water content of the dihydrate phosphogypsum is reduced to be less than 20%. According to the method, the water content of the dihydrate phosphogypsum can be reduced, the content of soluble acidic impurities is reduced, and good conditions are created for subsequent resource comprehensive utilization of the phosphogypsum.
本发明公开了一种低游离水二水磷石膏的生产方法及其生产系统，所述方法是将二水磷石膏先进行洗涤、过滤，再送入密封罩中用蒸汽吹扫，然后吸干，将二水磷石膏的含水率降至小于20%。本发明可将二水磷石膏的水份降低，可溶性酸性杂质含量降低，为后续磷石膏的资源化综合利用创造了良好条件。
