荆襄化工集团公司重钙厂装置包括两大相对独立部分。一部分是酸矿混合、化成和熟化生产粉状重钙 ,即粉肥生产线 ;另一部分是熟化料的造粒、干燥、筛分、冷却 ,即粒肥生产线。为充分发挥装置的效能 ,提出利用该装置生产 TSP、NPK、DAP、NP等产品的可行性。利用造粒干燥系统可改产硫基复合肥或 MAP、DAP;利用混化系统可改产尿基氮磷肥 ,该文分别介绍技改方案。
Jing Xiang Chemical Group Corporation plant contains two relatively independent of the independent part. Part of the acid mine is mixed, into and maturation production of powdered gypsum, that is, fertilizer production line; the other part is the maturing granulation, drying, screening, cooling, that is, fertilizer production line. In order to give full play to the effectiveness of the device, the feasibility of using the device to produce TSP, NPK, DAP, NP and other products is put forward. The use of granulation and drying system can be converted sulfur compound fertilizer or MAP, DAP; use of mixed system can be modified urine nitrogen and phosphorus fertilizer, the paper introduces the program of technological innovation.
