摘　　要：磷石膏渣场回水系统结垢会导致渣场回水量迅速降低,不但影响磷酸装置生产,还会使渣场水位上升,增加渣场运行的安全风险。分析磷石膏渣场回水系统结垢的原因,通过在磷石膏渣场回水系统增加换热器,利用磷石膏渣浆的热量加热渣场回水,解决了回水泵及回水管道结垢问题。Scaling in the backwater system of phosphogypsum slag field will lead to a rapid reduction of the backwater in the slag field,which not only affects the production of phosphoric acid plant,but also makes the water level of the slag field rise,increasing the safety risk of slag field operation.The cause of scaling in the backwater system of phosphogypsum slag field is analyzed,and solves the scaling problem of the backwater pump and the backwater pipe by adding heat exchanger in the backwater system of phosphogypsum slag field and heating the backwater with the heat of phosphogypsum slurry.
