The invention relates to an industrial shaft kiln for lime production. A kiln body internally includes a preheating zone, a calcining zone and a cooling zone, an upper suction beam is arranged on theupper part of the preheating zone, a lower suction beam is arranged on the upper part of the cooling zone, the preheating zone is provided with denitration beams, and the calcining zone is provided with upper combustion beams, upper auxiliary beams, lower combustion beams and lower auxiliary beams; the upper auxiliary beams are located on the lower parts of the upper combustion beams, the lower auxiliary beams are located on the lower parts of the lower combustion beams, and coal nozzles are formed in the tops of the upper combustion beams and the lower combustion beams; and injection air gunsare arranged at the two ends of the upper combustion beams and the lower combustion beams correspondingly. According to the provided industrial shaft kiln for lime production, by arranging a double-combustion-beam structure in the kiln body, and arranging the upper suction beam and the lower suction beam in a matched mode, the air inlet amount of a beam-type lime shaft kiln can be decreased, andemission of exhaust gas is reduced.
本发明涉及一种生产石灰的工业竖窑，窑体内包括预热带、煅烧带和冷却带，预热带的上部设有上抽吸梁，冷却带的上部设有下抽吸梁，预热带设有脱硝梁，煅烧带设有上燃烧梁、上辅助梁、下燃烧梁和下辅助梁；上辅助梁位于上燃烧梁的下部，下辅助梁于下辅助梁的下部，上燃烧梁和下燃烧梁的顶部设有喷煤嘴；上燃烧梁和下燃烧梁的两端分别设有引射风枪。本发明提供的生产石灰的工业竖窑通过在窑体内设置双燃烧梁结构，并配合设置上下吸气梁，能够减少梁式石灰竖窑的进风量，减少废气的排放。
