Cyclone preheater for granular materials
The invention relates to a cyclone preheater for granular materials. The cyclone preheater comprises a first-stage cyclone cylinder, a second-stage cyclone cylinder, a third-stage cyclone cylinder, a fourth-stage cyclone cylinder and a hot blast stove, wherein one side of the top of the first-stage cyclone cylinder communicates with the top of the second-stage cyclone cylinder through a first connecting air pipe, one side of the top of the second-stage cyclone cylinder communicates with the top of the third-stage cyclone cylinder through a third connecting air pipe, one side of the top of the third-stage cyclone cylinder communicates with the top of the fourth-stage cyclone cylinder through a second connecting air pipe, one side of the top of the fourth-stage cyclone cylinder is connected with a decomposing furnace through a material guide pipe, the bottom of the decomposing furnace communicates with an air conveying opening of the hot blast stove through a pipeline, and the decomposing furnace communicates with the bottom of the third-stage cyclone cylinder. According to the cyclone preheater for granular materials, limestone particle materials are preheated and decomposed step by step through the connecting air pipes and the preheating cyclone cylinders, the heat exchange efficiency is improved, the heat energy utilization rate can be increased, secondary processing is avoided, the power consumption and coal consumption of the system and the equipment investment cost are reduced, and the repair and maintenance workload is reduced.
本发明涉及一种颗粒料的旋风预热器，包括一级旋风筒、二级旋风筒、三级旋风筒、四级旋风筒和热风炉，一级旋风筒的顶部一侧通过第一联结风管与二级旋风筒的顶部相连通，二级旋风筒的顶部一侧通过第三联结风管与三级旋风筒的顶部相连通，三级旋风筒的顶部一侧通过第二联结风管与四级旋风筒的顶部相连通，四级旋风筒的顶部一侧通过导料管连接有分解炉，分解炉的底部通过管道与热风炉的输风口相连通，分解炉与三级旋风筒的底部相连通。本发明中各个联结风管和各个预热旋风筒分别对石灰石颗粒物料进逐级预热分解，提高了热交换效率，能够提高热能的利用率，避免二次加工，降低系统电耗、煤耗以及设备投资成本，减少维修、保养工作量。
