Cement rotary kiln system for disposing waste fan blades and working method of cement rotary kiln system
The invention discloses a cement rotary kiln system for disposing waste fan blades and a working method of the cement rotary kiln system, and belongs to the technical field of resource recovery. The cement rotary kiln system comprises a blade breaking and crushing system, a raw material feeding system, a flue gas treatment system, a suspension preheater, a decomposing furnace, a rotary kiln, a clinker cooling device and a blade particle pneumatic conveying system. Crushed fan blade particles are pneumatically conveyed into the decomposing furnace for pyrolysis and combustion, and a cyclone is arranged at the bottom of the decomposing furnace; heat released by combustion of an organic composite material and heat released by combustion of pulverized coal are used for preheating and decomposing raw materials together; and glass fibers in the blade particles also participate in forming the raw materials, and the glass fibers and the raw materials enter the rotary kiln together for firing clinker. The waste fan blades are effectively and comprehensively utilized, and combustion products are normally discharged together with coal-fired flue gas after being disposed by the flue gas treatment device arranged on the cement rotary kiln system. According to the cement rotary kiln system, harmless and resource treatment of the waste fan blades can be smoothly realized, and good environmental protection benefits and economic benefits are generated.
本发明公开的一种处置废弃风机叶片的水泥回转窑系统及其工作方法，属于资源回收技术领域。包括叶片破碎粉碎系统、生料进料系统、烟气处理系统、悬浮预热器、分解炉、回转窑、熟料冷却装置和叶片颗粒气力输送系统。破碎后的风机叶片颗粒经气力输送进入分解炉内热解并燃烧，分解炉底部设置旋流器；有机复合材料燃烧释放的热量同煤粉燃烧放热一并用于生料的预热与分解；叶片颗粒中玻璃纤维也参与形成生料，一并进入回转窑用于烧制熟料。废弃的风机叶片得到了有效的综合利用，燃烧产物随燃煤烟气一起，由水泥回转窑系统配备的烟气处理装置处置后实现正常排放。本发明可顺利实现风机废旧叶片的无害化与资源化处置，产生良好的环保效益与经济效益。
