Cement clinker calcining system and calcining method
The invention relates to the technical field of cement preparation, in particular to a calcining system and method for cement clinker. The calcining system comprises a kaolin calcining assembly which comprises a preheater and a decomposing furnace; the preheater is provided with a plurality of stages of cyclone cylinders; the preheater is provided with a feed port and a discharge port; the decomposing furnace is provided with a fuel adding port and a raw material inlet; the raw material inlet is connected with the discharge hole; calcining in the decomposing furnace to generate activated kaolin; the calcining temperature in the decomposing furnace is 700-850 DEG C, the calcining time is 0-1.5 hours, and the calcining atmosphere in the decomposing furnace is an oxygen-enriched atmosphere or a CO reduction atmosphere; the cement calcining assembly is used for calcining to generate cement clinker; and adding the activated kaolin into the discharging side of the cement calcining assembly according to a preset proportion of the activated kaolin in the cement clinker. The use of carbon-containing raw materials in clinker production can be reduced, the carbon emission of the clinker is reduced, and the hydration rate of the cement clinker is adjusted.
本发明涉及水泥制备技术领域，具体涉及一种水泥熟料的煅烧系统及煅烧方法。该煅烧系统包括：高岭土煅烧组件，包括预热器和分解炉；所述预热器，设置有多级旋风筒；所述预热器设置有进料口和出料口；所述分解炉，设置有燃料添加口以及生料进口；所述生料进口与所述出料口连接；所述分解炉煅烧生成活化高岭土；所述分解炉中的煅烧温度在700℃至850℃之间，煅烧时间为在0至1.5小时之间，且所述分解炉中的煅烧氛围为富氧氛围或CO还原氛围；水泥煅烧组件，用于煅烧生成水泥熟料；以所述活化高岭土在水泥熟料中的预定占比，向所述水泥煅烧组件的出料侧加入所述活化高岭土。能够降低熟料生产中含碳原材料的使用，降低熟料碳排放，调节水泥熟料的水化速率。
