Preparation and application method of mineralizer special for solid waste-based low-carbon cement clinker
The invention discloses a preparation and application method of a mineralizer special for solid-waste-based low-carbon cement clinker, and relates to the technical field of low-carbon cement clinker production.The preparation method comprises the following steps that S1, titanium gypsum is added into water, and a certain amount of ammonia water, phosphogypsum and a crystal form control agent are added; s2, the materials in the S1 are stirred and subjected to ultrasonic oscillation, and meanwhile cement kiln tail gas is introduced; s3, after the reaction is continued for a period of time, filtering the liquid in the S2; according to the method, multiple problems existing in a cement plant at present are integrated, the tail gas of the cement kiln is utilized for mineralizing and modifying the titanium gypsum to obtain the special mineralizer for the high-iron-phase low-carbon cement clinker, the special mineralizer is utilized for producing the low-carbon cement clinker, the main component of the mineralized titanium gypsum is calcium carbonate, the sulfur content is very low, and the high-iron-phase low-carbon cement clinker is obtained. The method can be used for producing the cement clinker in a large scale, the titanium gypsum solid waste can be consumed on a large scale, the produced cement clinker is the high-iron-phase low-carbon clinker, and the low-carbon cement has the advantages of being low in carbon emission, high in erosion resistance and good in fluidity.
本发明公开了一种固废基低碳水泥熟料专用矿化剂制备及应用方法，涉及低碳水泥熟料生产技术领域，包括以下步骤：S1：将钛石膏加入水中，并添加一定的氨水、磷石膏和晶型控制剂；S2：对S1中的物料进行搅拌和超声震荡，同时通入水泥窑尾气；S3：持续反应一段时间后，对S2中的液体进行过滤；本发明将水泥厂目前存在的多项问题进行整合，通过利用水泥窑尾气对钛石膏进行矿化改性，得到高铁相低碳水泥熟料专用矿化剂，并利用该专用矿化剂生产低碳水泥熟料，矿化钛石膏主要成分是碳酸钙，含硫量很低，可以大量用于水泥熟料生产，有利于大规模消纳钛石膏固废，且生产的水泥熟料为高铁相低碳熟料，此类低碳水泥具有碳排放低、抗侵蚀能力强、流动性好的特点。
