Drying kiln and process system for preparing lightweight aggregate from coal gangue
The invention discloses a drying kiln for preparing lightweight aggregate from coal gangue. The drying kiln comprises a kiln body, the rear portion of the kiln body is divided into a plurality of material chambers in the circumferential direction of the kiln body, each material chamber comprises arc-shaped plates installed on the inner wall of the kiln body, and the space defined by the arc-shaped plates in the kiln body is a smoke chamber. A feeding baffle plate corresponding to the position of the smoke chamber is also arranged in the kiln body. Meanwhile, the invention provides a process system for preparing the lightweight aggregate from the coal gangue. The material chambers and the smoke chamber are arranged in the kiln body of the drying kiln, an indirect heat transfer manner is adopted in the solid waste drying process, on one hand, materials are dried, on the other hand, waste heat recovery of smoke is increased, the drying effect is enhanced, heat energy loss is reduced, and the kiln tail flue gas emission temperature can be reduced by about 100 DEG C compared with the original temperature.
本发明公开一种用于煤矸石制作轻骨料的烘干窑，包括窑体，窑体的后部沿窑体的圆周方向分隔成数个物料室，每个物料室包括安装于窑体内壁的弧形板，窑体内数个弧形板围起来的空间为烟气室，窑体内还设置有与烟气室的位置相对应的进料挡板。同时提供一种用于煤矸石制作轻骨料的工艺系统。本发明通过在烘干窑的窑体内设置物料室和烟气室，在固体废弃物烘干过程中采取间接传热方式，一方面烘干物料，一方面增加烟气的余温回收，增强烘干效果，减少热能损耗，窑尾烟气排放温度能够比原来降低100℃左右。
