Energy-saving suspension roasting coal gangue treatment system and process
The invention relates to an energy-saving suspension roasting coal gangue treatment system. The system comprises calcination decarburization equipment, preheating equipment, cooling equipment and a dust collector, wherein the calcination decarburization equipment comprises a combustion chamber and a combustor, the preheating equipment comprises a first-stage preheater, a second-stage preheater anda third-stage preheater from top to bottom, the cooling equipment comprises a first-stage cooler, a second-stage cooler, a third-stage cooler, a fourth-stage cooler and a fluidization cooler from topto bottom, a feed port of the first-stage preheater communicates with coal gangue lifting equipment, discharge ports of the second-stage preheater and the third-stage preheater communicate with a feed port of the combustion chamber, a discharge port of the combustion chamber communicates with a feed port of the first-stage cooler, the fluidization cooler communicates with a finished product warehouse, an exhaust port in the top of the second-stage preheater communicates with coal gangue lifting equipment through a backflow air channel, an exhaust port in the top of the first-stage preheater communicates with a dust collector, and the dust collector communicates with a feeding port of the second-stage cooler. According to the system, materials treated through the system can serve as semi-finished products to be used in the next working section and can serve as coal ash finished products.
本发明涉及节能型悬浮焙烧煤矸石处理系统，包括煅烧脱碳设备、预热设备、冷却设备及收尘器，煅烧脱碳设备包括燃烧室和燃烧器，预热设备包括自上而下的一级、二级以及三级预热器，冷却设备包括自上而下的一级、二级、三级、四级冷却器和流态化冷却器；一级预热器的进料口与煤矸石提升设备连通，二级、三级预热器的出料口分别与燃烧室的进料口连通，燃烧室的出料口与一级冷却器的进料口连通，流态化冷却器与成品储库连通；二级预热器的顶部排气口通过回流气道与煤矸石提升设备连通，一级预热器的顶部排气口与收尘器连通，收尘器与二级冷却器的进料口连通，经该系统处理的物料可作为半成品供下一工段使用，也可以做为粉煤灰成品。
