Abstract
本发明公开了一种碱性固废矿化CO2的超重力多层环隙反应系统及其运行方法。该系统主要包括旋转电机、传动轴、轴封、旋转多孔筒、静止多孔筒、反应器外壳、气体出口、液体入口、液体出口、气体入口、气源、浆液泵、碱性固废制浆罐。利用旋转多孔筒、静止多孔筒间的环形孔隙作为流动通道，借助高速旋转的动圆筒带动流体切向运动，在离心力的作用下形成超重力环境，提高CO2传质效率；在圆筒侧壁打孔作为气体运移通道，兼具延长流道和碰撞剪切的功能，可以延长停留时间、避免气泡聚并；有效避免放大效应问题，只需增加反应器内径和动静圆筒数量，即可实现高效矿化大流量CO2，有助于推动碱性固废矿化CO2技术的工业应用。
