Method for recycling nitrogen oxide in cement kiln flue gas, and application thereof
The invention provides a method for recycling nitrogen oxide in cement kiln flue gas. The method comprises the following steps: mixing ozone and cement kiln flue gas to obtain nitrogen fixation clinker, wherein the cement kiln flue gas carries cement clinker particles, and the concentration of the cement clinker particles is 100-1500 mg/Nm<3>. According to the invention, the method is low in costand easy to implement, under the condition that the kiln condition of the cement kiln is stable, the denitration efficiency in the cement kiln flue gas is 33.2-85.2%, and the removed nitrogen oxide isrecycled, so that the environmental pressure is reduced, the economic benefits of enterprises are increased, and the quality of cement products is improved.
本发明提供了一种水泥窑烟气中氮氧化物回收再利用的方法，所述方法包括如下步骤：臭氧与水泥窑烟气混合，得到固氮熟料；水泥窑烟气夹带有水泥熟料颗粒，其中水泥熟料颗粒的浓度为100‑1500mg/Nm。该方法成本低廉，易于实现，在水泥窑窑况稳定的情况下，水泥窑烟气中的脱硝效率为33.2‑85.2％，而且还将脱除的氮氧化物进行了再利用，降低了环境压力，提高了企业的经济效益并且改善了水泥产品的质量。
