Novel cement clinker calcining and decomposing furnace
The invention provides a novel cement clinker calcining and decomposing furnace. The novel cement clinker calcining and decomposing furnace comprises a lower volute part, a lower furnace body, an upper furnace body and an upper volute part. The lower volute part comprises a lower volute flow channel and an air inlet, and the lower volute flow channel feeds gas into the lower volute part through an outlet tangentially communicating with the side wall of the lower volute part; the lower volute runner is communicated with a first to-be-calcined material inlet and a first fuel inlet, and/or the side wall of the lower volute part is provided with a second to-be-calcined material inlet and a second fuel inlet. A shrinkage part is arranged at the bottom of the upper furnace body, and the diameter of the shrinkage part is gradually increased in the vertical upward direction. And an upper side outlet communicated with the upper volute part is formed in the side surface of the upper furnace body. The upper volute part comprises an upper volute flow channel, an inlet of the upper volute flow channel is configured to tangentially communicate with the upper side outlet, and the rotating direction of the upper volute flow channel is opposite to that of the lower volute flow channel. According to the calcining decomposing furnace, the retention time of fuel and flue gas can be prolonged, and meanwhile, the to-be-calcined material, the fuel and the flue gas are fully mixed.
本发明提供一种新型水泥熟料煅烧分解炉，包括下蜗壳部、下炉体、上炉体和上蜗壳部。下蜗壳部包含下蜗壳流道和进风口，下蜗壳流道经由与下蜗壳部的侧壁切向连通的出口将气体送入下蜗壳部；下蜗壳流道连通有第一待煅烧物料入口和第一燃料入口和/或下蜗壳部的侧壁布置有第二待煅烧物料入口和第二燃料入口。上炉体的底部设置收缩部，收缩部构造为直径沿竖直向上方向逐渐增大。上炉体侧面设置有与上蜗壳部连通的上侧出口。上蜗壳部包括有上蜗壳流道，上蜗壳流道的入口被配置为切向连通至上侧出口，上蜗壳流道的旋转方向与下蜗壳流道的旋转方向相反。根据本发明的煅烧分解炉，可以提高燃料及烟气停留时间，同时使待煅烧物料、燃料与烟气充分混合。
