一种可协同固碳的有压热闷钢渣预处理装置

Abstract

本申请公开了一种可协同固碳的有压热闷钢渣预处理装置，第二罐体的罐口低于第一罐体的罐口；罐盖铰接于第二罐体，罐盖设置有驱动件，供水组件的输入端与外部水源的输出端连通，其输出端伸入第二罐体；供气组件的输入端与窑炉废气收集系统的输出端连通，其输出端伸入第一罐体；搅拌组件设置于罐盖的顶部，其输出端竖直伸入第二罐体。本申请中供水组件将热水引入第二罐体内部，与钢渣中的游离氧化钙、氧化镁发生水化反应，消除体积膨胀隐患。供气组件将含CO2的窑炉废气导入两罐体之间，利用钢渣余热促进碳酸盐化反应实现固碳。搅拌组件从罐盖顶部垂直伸入第二罐体，加速钢渣与水和CO2的接触反应，从而提高钢渣热闷预处理过程中的固碳效果。
