The invention discloses a multi-arch-bridge lime shaft kiln which comprises a shaft kiln body, a stock bin is installed at the top end of the shaft kiln body, a feeding hopper is installed at the top end of the stock bin, a smoke exhaust beam is installed at the top end of an inner cavity of the shaft kiln body, and roasting arches are installed at the top end of the inner cavity of the shaft kiln body. A hot air exhaust arch is installed in the center of an inner cavity of the shaft kiln body, and a cooling air inlet arch is installed at the bottom end of the inner cavity of the shaft kiln body. According to the multi-arch-bridge lime shaft kiln, the kiln type of the novel shaft kiln with the multi-arch material distribution beams is adopted, decomposed raw materials are placed in the space in the kiln, two inner walls of the shaft kiln are connected through the multiple layers of material distribution arches, and the shaft kiln is simple in structure and can be formed into a multi-chamber annular combination. Meanwhile the mode that the combustion process and the heat transfer process are independent is adopted, and a multi-arch structure is adopted in the kiln, and a boiling cooling mode is adopted in a cooling zone in the kiln, so that the raw material granularity application range is large (the particle fraction ratio is 2.5), the product quality is good (the reduction is less than 5%), the kiln utilization coefficient is high (1.25), and energy conservation and environmental protection are realized.
本发明公开了一种多拱桥石灰竖窑，包括竖窑主体，所述竖窑主体的顶端安装有料仓，所述料仓的顶端安装有上料斗，所述竖窑主体的内腔顶端安装有排烟梁，所述竖窑主体的内腔顶端安装有焙烧拱，所述竖窑主体的内腔中心位置安装有热风排出拱，所述竖窑主体的内腔底端安装有冷却风进入拱。该多拱桥石灰竖窑，采用带有多拱分料梁新型竖窑的窑型，被分解的原料置于窑内空间，竖窑的内两墙之间由多层分料拱相连，竖窑结构简单，可行成多个“室”环形组合，同时采用燃烧和传热过程分别独立方式，且窑内采用多拱结构和窑内冷却带采用沸腾冷却方式，使原料粒度适用范围大（粒级比2.5），产品质量好（酌减＜5%）、窑利用系数高（1.25），节能环保。
