Method for denitration by using electrolytic manganese residues in cement clinker production line
The invention discloses a method for denitration by using electrolytic manganese residues in a cement clinker production line, and belongs to the technical field of cement production. The invention discloses a method for denitration by using electrolytic manganese residues in a cement clinker production line. The method comprises the following steps: arranging a material crushing and metering device; a material mixing and fine crushing device is arranged to disperse the materials treated by the material crushing and metering device; the step of dispersing is that the crushed and metered materials are mixed and crushed again to obtain fine crushed materials in a coated state, the interior of the fine crushed materials is the electrolytic manganese residues, and the exterior of the fine crushed materials is non-alkaline fine powder, so that the metering and proportioning of the electrolytic manganese residues and the non-alkaline fine powder are completed, and the purpose of dispersing the electrolytic manganese residues is achieved; and the fine crushed materials effectively react with nitrogen oxides in the kiln tail uptake flue or the decomposing furnace in the kiln tail uptake flue or the decomposing furnace, so that denitration treatment in the cement clinker production process is achieved. The equipment is simple, convenient and low in cost, a waste recycling method is environmentally friendly, cement clinker denitration can be achieved, and the quality of cement clinker is guaranteed.
本发明公开了一种水泥熟料生产线中利用电解锰渣脱硝的方法，属于水泥生产技术领域。一种水泥熟料生产线中利用电解锰渣脱硝的方法，包括：设置物料粉碎计量装置；设置物料混合细碎装置，对经过物料粉碎计量装置处理后的物料进行分散；所述分散为对粉碎、计量后的物料进行混合、再粉碎，得到呈包覆态的细碎物料，所述细碎物料内部为电解锰渣，外部为非碱性细粉料，从而完成电解锰渣与非碱性细粉料的计量配比，达到电解锰渣分散目的；所述细碎物料在窑尾上升烟道或分解炉内与窑尾上升烟道或分解炉内的氮氧化物有效反应，达到水泥熟料生产过程脱硝处置。该设备简易便捷，成本低，废物再利用方法环保，可实现水泥熟料脱硝，保证水泥熟料质量。
