Nested cyclone preheater capable of preheating twice
The invention relates to the field of cement production equipment, in particular to a nested cyclone preheater capable of preheating twice, which comprises a cyclone inner cylinder, a cyclone outer cylinder, a mixing outer cylinder and a mixing inner cylinder, the upper end of the circumferential wall of the cyclone inner cylinder is provided with an inner air inlet arranged along the tangential direction of the cylinder wall; an air outlet pipe is arranged at the top of the cyclone inner cylinder, and an inner feed opening is formed in the bottom of the cyclone inner cylinder; air guide and heat exchange among all stages of cyclone preheaters are carried out through the space in the cylinder, heat exchange pipes which are connected in a left-right crossed mode are replaced, and the problems of material accumulation and caking generated at the strong bending position of an original heat exchange pipe pipeline are solved; according to the multistage cyclone preheating system, the cyclone inner cylinder and the cyclone outer cylinder which are nested are arranged, so that the primary cyclone preheater can perform heat exchange separation twice inside and outside, the overall height of the multistage cyclone preheating system is greatly reduced, the system cost is greatly reduced, and the gas pressure loss is reduced.
本发明涉及水泥生产设备领域，具体涉及一种进行两次预热的嵌套式旋风预热器，包括旋风内筒、旋风外筒、混合外筒、混合内筒；所述旋风内筒的圆周壁上端设有沿筒壁切向方向布置的内进风口；所述旋风内筒的顶部设有出风管，底部设有内下料口；本发明通过利用筒内空间进行各级旋风预热器之间的导气与换热，替代左右交叉连接的换热管，避免了原有换热管管道强烈弯曲处产生的材料积累和结块问题；通过设置嵌套的旋风内筒与旋风外筒，使得一级旋风预热器能够在内外进行两次换热分离，大大减少了多级旋风预热系统的整体高度，大大降低了系统成本，减少了气体压力损失。
