一种钢渣余热回收与钢渣综合加工利用的方法

Abstract

一种钢渣余热回收与钢渣综合加工利用的方法,属于钢渣处理技术领域。通过热态钢渣倒料系统,将钢渣倾倒于热态钢渣受料系统中进行初步破碎;破碎后的钢渣经由热态钢渣流速控制系统,经过二次破碎后定量给至热态钢渣冷却粒化系统中再次进行破碎和冷却,冷却过程中产生的高温热风通过热态钢渣余热回收系统收集后,进入热交换系统,形成蒸汽用于发电或供热;冷却后的钢渣进入钢渣稳定化处理系统,经过稳定化处理后的钢渣,通过渣钢分离系统,分别获得钢渣尾渣微粉和金属渣钢;钢渣微粉与其他物料配合后,通过钢渣混凝土制品加工制备系统进行混凝土制品制备。优点在于,具有处理钢渣的种类适应范围广、操作环境好、无二次污染。
The invention provides a mehtod for recovering waste heat of steel slag and comprehensively processing and using the steel slag, and belongs to the technical field of steel slag treatment. The method comprises the following steps: a thermal state steel slag material discharging system discharges steel slag into a thermal state steel slag material receiving system for primary crushing; the crushed steel slag is subjected to secondary crushing by a thermal state steel slag velocity control system and quantificationally fed into a thermal state steel slag cooling granulating system for re-crushing and cooling, high-temperaure hot air generatd in the cooling process is collected by a thermal state steel slag waste heat recovery system and enters a heat exchange system to form vapor for power generation or heat supply; the cooled steel slag enters a steel slag stabilizing treatment system, and the steel slag after the stabilizing treatment is treated by a steel slag separation system to obtain steel slag tailing micropowder and metal slag steel respectively; and, the steel slag micropowder is mixed with other materials and used to prepare concrete products by a steel slag concrete product processing preparation system. The method has the advantages of adaptability to various types of steel slag to be processed, good operational environment and no secondary pollution.
