一种间壁式回转窑装置
摘要：
本发明涉及一种间壁式回转窑装置，包括回转窑、烟气余热发电设备、气体回收处理设备、冷却器、助燃风机、上料系统和废气排放系统。窑体的耐材砌体为由耐材内筒和耐材外筒构成的空心结构。耐材内筒的中心为窑膛，耐材内筒和耐材外筒之间为物料通道，物料通道设有耐材支撑或含有通道的耐火砌体。上料系统通过原料预热仓或间壁预热器与加料设备连接。加料设备设有分解气体出口，分解气体出口通过原料预热仓或间壁预热器连接到气体回收处理设备，窑膛通过窑尾罩连接到烟气余热发电设备。本发明由窑壁和同轴安装的耐材内筒和耐材外筒构成的窑体，避免烟气与物料直接接触，提高了被加热或煅烧产品的质量，有利于回收利用分解气体，增加副产收入和企业的经济效益。
摘要（英）：

A dividing-wall rotary kiln device comprises a rotary kiln, an exhaust gas residual-heat power generation device, a gas recovery processing device, a cooler, a combustion fan, a feeding system and an exhaust emission system. A refractory brick unit of a kiln body is a hollow structure formed by a refractory inner cylinder and a refractory outer cylinder. A center of the refractory inner cylinder is a kiln chamber. A material channel is between the refractory inner cylinder and the refractory outer cylinder. The feeding system is connected to a feeding device via a raw material preheating compartment or a dividing-wall preheater. The feeding device is provided with a decomposition gas outlet connected to the gas recovery processing device via the raw material preheating compartment or the dividing-wall preheater. The kiln chamber is connected to the exhaust gas residual-heat power generation device via a kiln tail hood.
