Tower type reheating sintering shaft kiln for magnesite sintering
The invention belongs to the technical field of kilns, and particularly relates to a tower type reheating sintering shaft kiln for magnesite sintering, which comprises a kiln body, an air cooler, a hot air pipeline, a gravity dust collector and an external combustor, and is characterized in that the kiln body is sequentially divided into a material storage smoke discharge layer, a preheating layer, a sintering layer, a homogenization heat exchange layer and a cooling layer from top to bottom according to a production process; middle beams are arranged between the layers, at least one layer of the kiln body is of a split prefabricated structure, the split prefabricated structures are formed through independent pouring and then spliced and built into the whole kiln body on site, and the size and the number of the split prefabricated structures are adjusted according to the thermal regulation in the kiln. The tower type reheating sintering shaft kiln has the beneficial effects that (1) the multi-layer prefabricated combined structure is adopted, all layers of kiln bodies are mutually independent and mutually supported, and the workload of earthwork and pouring of site construction is reduced; and (2) gas channels are arranged on the middle beams among the layers of the kiln body, so that the temperature of each process section can be adjusted through hot flue gas and cold air, and the process conditions can be flexibly controlled.
本发明属于窑炉技术领域，具体涉及一种菱镁矿烧结用塔式复热烧结竖窑，包括窑体、冷风机、热风管道、重力除尘器和外置燃烧器，其特征在于，窑体根据生产工艺由上到下依次分为储料排烟层、预热层、烧结层、均化换热层和冷却层，各层之间设有中间梁，至少一层窑体为分体预制结构，分体预制结构先经独立浇注成形，然后在现场拼接砌筑成整个窑体，各分体预制结构的大小和数量根据窑内热工制度进行调节。本发明的有益效果是：1）采用多层预制组合结构，各层窑体彼此相互独立并且相互支撑，减少现场施工的土方和浇注的工作量；2）各层窑体之间的中间梁上设有气体通道，可通过热烟气和冷空气进行各工艺区间的温度调节，并可灵活控制工艺条件。
