Phosphogypsum calcining method
The invention provides a phosphogypsum calcining method, belonging to the field of phosphogypsum calcining. The phosphogypsum calcining method comprises the following steps: 1, mounting a flaming device at one end of a calcining roller, and ensuring that the air supply direction and the flaming direction of the flaming device face the port of the same end of the calcining roller; 2, allowing the phosphogypsum to run along the route and direction that the phosphogypsum enters a feed conveying device at first, then flows to the flaming end of a calcining furnace, then enters the inner cavity of the calcining roller, circulates multiple times in the inner cavity of the calcining roller along the axial direction of the calcining roller, then returns to the flaming end of the calcining furnace and is finally output to the calcining roller; and 3, enabling airflow to to run along the route and direction that air enters from the flaming end of the calcining furnace, then enters the inner cavity of the calcining roller, circulates in the calcining roller along the axial direction of the calcining roller and in a direction opposite to the running direction of the phosphogypsum, returns to the flaming end of the calcining furnace, and is discharged from the flaming end of the calcining furnace to enter a dust removal system. The method has the characteristic that heat energy is fully utilized.
一种磷石膏煅烧方法，属于磷石膏煅烧领域，包括以下方法，1、将喷火装置安装在煅烧滚筒的一端，保证喷火装置的送风方向和喷火方向朝向煅烧滚筒的同一端端口；2、磷石膏的运行路线和方向是：进料输送装置——煅烧炉喷火一端——进入煅烧滚筒内腔——在煅烧滚筒内腔沿煅烧滚筒轴向多次循环——回到煅烧炉喷火一端——输出到煅烧滚筒；3、气流的运行路线是：从煅烧炉的喷火一端进风——进入煅烧滚筒内腔——在煅烧滚筒内沿煅烧滚筒轴向循环并与磷石膏运行方向相反——回到煅烧炉喷火一端——从煅烧炉喷火一端排出进入除尘系统，具有煅烧效率高，热能利用充分的特点。
