Phosphogypsum closed internal circulation pretreatment process
The invention relates to a phosphogypsum closed internal circulation pretreatment process, and belongs to the field of building materials. The process comprises the four steps of material mixing, material purification, material dehydration and water treatment-recovery. The material mixing is carried out by a material mixing system. A material purification system is composed of two purification reaction tanks. A material dehydration system is composed of a filter press and a hot air dryer. The water treatment-recovery is carried out by a system consisting of sewage purification equipment, a condensing tower and a water pump. The whole process forms a closed loop, and has the advantages of simple flow, convenience in operation, good phosphogypsum pretreatment effect, environmental protection and no pollution.
本发明涉及一种磷石膏封闭式内循环预处理工艺，属于建筑材料领域。本发明包括物料混合、物料净化、物料脱水、水处理‑回收四个步骤；所述物料混合由物料混合系统承担；净物料化系由两座净化反应池构成；物料脱水由压滤机和热风干燥机组成；水处理‑回收是由污水净化设备、冷凝塔、水泵组成的系统承担。整各工艺形成闭环整体，具有流程简单，操作便捷，磷石膏预处理效果良好，环保无污染的优点。
