Method for applying red mud to zero carbon emission in cement production
The invention discloses a method for applying red mud to zero carbon emission in cement production, which comprises the following steps: S1, pretreatment: mixing and activating red mud and tail gas generated in cement production; s2, reactants obtained after the red mud and the tail gas are mixed and activated are subjected to separation treatment through an electromagnetic separator and a gravity separator, and the reactants are separated into metal solids, non-metal solids and purified water; s3, mixing the metal solid and the non-metal solid, and then carrying out pyrolytic reaction; s4, performing electromagnetic separation on reactants after the pyrolytic reaction, and separating the reactants into carbonate solid powder and non-carbonate solid powder; s5, the non-carbonate solid powder is subjected to petrochemical treatment; and S6, crushing after petrochemical treatment to prepare the cement clinker. The method has the advantages that the red mud can be fully treated, the red mud is used for treating carbon dioxide in a cement plant, waste is treated with waste, resources are saved, and the treatment cost is reduced.
本发明公开了一种将赤泥用于水泥生产零碳排放的方法，包括以下步骤：S1、预处理，将赤泥与水泥生产中产生的尾气进行混合活化处理；S2、将赤泥与尾气混合活化处理后的反应物通过电磁分离器与重选器进行分离处理，并将反应物分离为金属固体、非金属固体和净化水；S3、对金属固体和非金属固体混合后进行热解反应；S4、将热解反应后的反应物进行电磁分离，并分离为碳酸盐固体粉末与非碳酸盐固体粉末；S5、将非碳酸盐固体粉末进行石化处理；S6、石化处理后进行粉碎，制成水泥熟料。本发明具有能充分处理赤泥，并将赤泥用于水泥厂二氧化碳的处理，实现以废治废，节约资源，降低处理成本的优点。
