Active mineral material for removing polymorphic mercury in cement kiln flue gas as well as preparation method and application of active mineral material
The invention discloses an active mineral material for removing polymorphic mercury in cement kiln flue gas as well as a preparation method and application of the active mineral material. According to the invention, by introducing the active substance, effective regulation and control of the size and aperture structure of the mineral particles are realized, and the active mineral material is synthesized. The active mineral material can be directly sprayed into cement kiln flue gas, high-concentration oxidation-state mercury and elemental mercury in the flue gas are converted into stable mercury compounds, the stable mercury compounds are removed in a dust remover along with kiln dust, and the kiln dust generated in the process can be directly added into a cement mill, so that the cement mill is environment-friendly. The mercury circulation in the cement kiln is effectively solved while the use of the kiln dust is not influenced, and the efficient fixation of the mercury in the flue gas of the cement kiln is realized. The material has the characteristics of simple and convenient synthesis method, suitability for cooperative capture of polymorphic mercury, high efficiency, wide flue gas temperature window, excellent stability of demercuration products, harmlessness to kiln dust, mature application method and the like in preparation and application, and has a good application prospect in cement kiln flue gas mercury control.
本发明公开了一种用于脱除水泥窑烟气中多形态汞的活性矿物材料及其制备方法和应用。本发明通过引入活性物质实现了矿物颗粒的尺寸与孔径结构的有效调控，合成了活性矿物材料。本发明的活性矿物材料可直接喷射到水泥窑烟气中，将烟气中高浓度氧化态汞与单质汞转化为稳定的汞化合物，随窑灰一同在除尘器被脱除，该过程产生的窑灰可直接添加到水泥磨中，在不影响窑灰使用的同时有效解决了水泥窑内的汞循环，实现了水泥窑烟气汞的高效固定。该材料的制备和应用上具有合成方法简便、适用多形态汞协同捕获、效率高、烟气温度窗口宽、脱汞产物稳定性优异、对窑灰无害、应用方法成熟等特性，具备良好的水泥窑烟气汞控制应用前景。
