Steel slag pressurized carbonization synergistic stabilization treatment method
The invention discloses a steel slag pressurized carbonization synergistic stabilization treatment method, which comprises the following steps: autoclaving stabilization treatment and low-pressure carbonization synergistic treatment: firstly carrying out stabilization treatment on steel slag in a saturated water vapor environment, and then carrying out low-pressure carbonization and stabilization synchronous treatment on the steel slag in a mixed gas of CO2 and air with certain pressure, humidity and concentration, wherein the pressure of the saturated water vapor is less than 2.0 MPa, the pressure of the mixed gas of CO2 and air is 0.1-0.5 MPa, the concentration of CO2 in the mixed gas is 10-30%, and the relative humidity is 65-75%. According to the method disclosed by the invention, f-CaO and f-MgO in the steel slag can be fully digested in a saturated water vapor environment, and then low-pressure carbonization cooperative treatment is carried out, so that the dual effects of steel slag stabilization and effective carbon sequestration are realized.
本发明公开了一种钢渣有压碳化协同安定化处理方法，包括：压蒸法安定化处理和低压碳化协同处理，即钢渣先在饱和水蒸汽环境中进行安定化处理，然后置于一定压力、湿度和浓度的CO2与空气的混合气体中进行低压碳化和安定化同步处理，其中饱和水蒸汽压力＜2.0MPa，CO2与空气的混合气体压力为0.1～0.5MPa，混合气体中CO2的浓度为10％～30％，相对湿度为65％～75％。本发明的方法可以使钢渣中的f‑CaO和f‑MgO先在饱和水蒸汽环境中充分消解，然后进行低压碳化协同处理，实现钢渣安定化并且有效固碳的双重效果。
