Ferronickel slag active exciting agent, active ferronickel slag powder thereof and preparation method of active ferronickel slag active exciting agent and active ferronickel slag powder
The invention discloses a ferronickel slag active exciting agent, active ferronickel slag powder thereof and a preparation method of the ferronickel slag active exciting agent. The electric furnace ferronickel slag active exciting agent is obtained by uniformly mixing and grinding dihydrate gypsum, calcium montmorillonite, sludge powder, a nanometer aluminum oxide precursor, potassium permanganate, raney nickel and La2O3, then the active exciting agent is sprayed into flow-state electric furnace ferronickel slag discharged from a boiler, uniform mixing is performed, the temperature is reduced to the normal temperature, treatment and grinding are performed, and active ferronickel slag powder is obtained. According to the active exciting agent disclosed by the invention, the gas content of the ferronickel slag can be increased, the grindability of the ferronickel slag is improved and the activity of the ferronickel slag is greatly improved through activity excitation among the components of the ferronickel slag in the active exciting agent; the resource utilization of the sludge is realized, and the environmental pollution is reduced.
本发明公开了一种镍铁渣活性激发剂、其活性镍铁渣粉及制备方法。本发明所述电炉镍铁渣活性激发剂由二水石膏、钙蒙脱石、污泥粉、纳米氧化铝前驱体、高锰酸钾、雷尼镍、La2O3混合均匀并粉磨得到，之后向从锅炉排出的流态电炉镍铁渣中喷入上述活性激发剂，混合均匀，再降至常温处理研磨，得到活性镍铁渣粉。本发明所述活性激发剂中各组分电炉镍铁渣之间的活性的激发，可增加镍铁渣含气量，提高镍铁渣易磨性，极大地提高镍铁渣活性；且实现污泥的资源化利用，减少环境污染。
