Heat radiation type calcining kiln
The invention provides a thermal radiation type calcining kiln, and belongs to the technical field of calcining kilns, the thermal radiation type calcining kiln comprises a feeding device used for lifting materials to the calcining kiln; the calcining kiln is used for calcining the materials, and the calcining kiln comprises a preheating zone used for preheating the materials, a calcining zone used for calcining the materials and a cooling zone used for cooling the calcined materials; the waste gas treatment system is used for treating waste gas generated by combustion; small materials with the diameter smaller than 20 mm can be calcined, and the problems that in the small-particle calcining process, knots are prone to occurring, air permeability is poor, the small-particle utilization rate is low, and resources are wasted are solved. In the use process, the knots are avoided, the difficulty of the production operation process is reduced, the combustion heat can be fully utilized, and the purposes of energy conservation and emission reduction are achieved; through radiation heat transfer, materials are not in direct contact with flames, so that heating is uniform, the half-curing rate is low, open fire does not exist in the kiln, too large ash cannot be generated, and the purity of sintered clinker is high.
本发明提供一种热辐射式煅烧窑，属于煅烧窑技术领域，包括上料装置，用于将物料提升至煅烧窑；煅烧窑，用于对物料进行煅烧，煅烧窑包括用于对物料预热的预热带、用于对物料煅烧的煅烧带以及用于对煅烧后物料进行冷却的冷却带；废气处理系统，将燃烧产生的废气进行处理；本发明可以煅烧直径小于20mm的小物料，解决了小颗粒煅烧过程中易接瘤、透气性差的问题，以及小颗粒利用率低资源浪费的问题。在使用的过程中不会接瘤，对生产操作工艺降低难度，燃烧的热量也能够充分利用，实现了节能减排的目的；通过辐射传热，物料没有直接接触火焰，使得受热均匀，夹生率较低，并且没有明火在窑炉内部，不会产生太大的灰，使得烧成的熟料纯度较高。
