摘　　要：以粉煤灰、电石渣及精炼废渣3种固体废渣为原料,通过调节废渣配比、微波改性等手段制备了烟气吸附剂。结果表明,按粉煤灰∶电石渣质量比1∶1进行混料,同时对精炼废渣进行微波改性处理(微波功率200 W、改性时间30 min),再按粉煤灰与电石渣总量的50%配加微波改性后的精炼废渣,在10 MPa压力下压制成型,所得烧结烟气吸附剂吸附性能较好,脱硫率达到了97.9%,脱硝率达到了93.0%。Three kinds of solid wastes including fly ash,carbide slag and refining slag were taken as raw materials for preparing a kind of absorbent by adopting microwave modification method and adjusting the proportions of three wastes.Fly ash was mixed with carbide slag in a mass ratio of 1∶1,and refining slag was modified by microwave(with microwave power of 200 W,time of 30 min),which was then added in quantities of 50%by total weight of fly ash and carbide slag.All mixed materials were then pressed under the pressure of 10 MPa,and the prepared adsorbent showed to have a good adsorption performance,with which the desulfurization rate and denitration rate for the sintering flue gas can reach 97.9%and 93.0%,respectively.
