Double-rectangular-chamber heat storage concurrent flow lime shaft kiln
The invention discloses a double-rectangular-chamber heat storage concurrent flow lime shaft kiln, which comprises two kiln bodies. Kiln chambers of the two kiln bodies are communicated. Each kiln body is composed of a shell and a refractory kiln lining built on the inner wall of the shell, a cavity in the middle of the kiln lining is a kiln chamber, the cross section of the kiln chamber is rectangular, the kiln chamber is sequentially divided into a preheating zone, a calcining zone and a cooling zone from top to bottom, a fuel spray gun, a combustion-supporting air inlet pipe and a smoke exhaust pipe are arranged in the preheating zone, a cooling air supply pipe and a connecting channel penetrating through the kiln chambers in the two kiln bodies are arranged in the cooling zone, and ignition and oven burners are arranged in the connecting channel. A limestone feeding device is arranged outside the kiln bodies, and an ash discharging device is arranged at the bottoms of the kiln bodies. The kiln chambers with a rectangular cross section are adopted, the kiln lining brick is simple in shape and convenient to install and maintain, when a large-capacity lime kiln is designed, the yield can be increased only by lengthening the long edges of the rectangle, the short edges of the rectangle are not changed, and the arrangement structure of the fuel spray gun is not changed.
一种双矩形膛蓄热并流石灰竖窑，包括两个窑体，两个窑体的窑膛连通；每个窑体由外壳以及砌筑在外壳内壁的耐火窑衬构成，窑衬中间的空腔为窑膛，窑膛的横截面为矩形，窑膛自上至下依次分为预热带、煅烧带和冷却带，预热带中设有燃料喷枪、助燃空气通入管和烟气排出管，冷却带中设有冷却风供给管以及贯通两个窑体中窑膛的连接通道，连接通道内设置点火和烘炉烧嘴。所述窑体外侧设置石灰石供料装置，所述窑体底部设置出灰装置。本发明采用矩形横截面窑膛，窑衬砖型简单，安装维修便捷，当设计大产能石灰窑时，只需将矩形的长边加长就能加大产量，而矩形的短边不变，燃料喷枪的布置结构不变。
