Cement production line-based calcined coal gangue composite clinker low-carbon preparation system and preparation method
The invention discloses a calcined coal gangue composite clinker low-carbon preparation system based on a cement production line and a preparation method. The calcined coal gangue composite clinker low-carbon preparation system comprises a cooling machine, a vertical cylinder preheater, a cyclone separator, a pre-dehydroxylation device, a condenser and an oil-water separator, according to the present invention, the coal gangue is calcined by using the pre-dehydroxylation device in combination with the cooling machine to prepare the composite clinker, the removed water does not enter the cement kiln firing system, the pre-dehydroxylated high-temperature coal gangue is calcined and activated in the cooling machine, the method has characteristics of simple process, small influence on the cement kiln firing system, and the prepared calcined coal gangue active material has characteristics of good quality, low cost, and wide application prospect. The coal gangue treatment amount is large, the calorific value utilization rate is high, energy consumption and carbon emission of the cement industry can be reduced, and good economic benefits and social benefits are achieved.
本发明公开了一种基于水泥生产线的煅烧煤矸石复合熟料低碳制备系统及制备方法，包括冷却机、立筒预热器、旋风分离器、预脱羟基器、冷凝器和油水分离器；本发明提出利用预脱羟基器，结合冷却机煅烧煤矸石制备复合熟料，脱除的水份不进入水泥窑烧成系统，预脱羟基的高温煤矸石在冷却机内煅烧活化，该方法工艺简单，对水泥窑烧成系统影响小，制备的煅烧煤矸石活性材料品质好、成本低廉，煤矸石处置量大，热值利用率高，能降低水泥行业的能耗与碳排放，具有较好的经济效益和社会效益。
