Cement kiln co-processing bypass air release system
The invention discloses a cement kiln co-processing bypass air release system and relates to the technical field of sludge treatment. The cement kiln co-processing bypass air release system comprisesa rotary kiln, a kiln tail smoke chamber and a kiln end preheater; a waste gas opening is formed in the upper side part of the kiln tail smoke chamber; the inner wall of the waste gas opening is connected with an air inducing pipe; the tail end of the air inducing pipe is connected with a bypass air release waste heat boiler; the kiln tail preheater comprises a decomposing furnace and a multi-stage cyclone; the multi-stage cyclone is connected with a kiln tail SP waste heat boiler; the kiln tail SP waste heat boiler is connected with a grate cooler; a feed port of the kiln tail smoke chamber in the rotary kiln is connected with a discharge port of the kiln tail preheater; and a waste gas outlet of the kiln tail preheater is connected with the kiln tail SP waste heat boiler. According to the cement kiln co-processing bypass air release system, through the effects of the air inducing pipe, the bypass air release waste heat boiler, the multi-stage cyclone, the kiln tail SP waste heat boiler and the grate cooler, dust falling and dust collection of the smoke are facilitated in the heat exchange process of the boiler, the influence of smoke dust on operation of the kiln tail waste heatboiler is avoided, energy consumption can be reduced, and stable operation of the kiln tail SP waste heat boiler is guaranteed.
本发明公开了一种水泥窑协同处理的旁路放风系统，涉及污泥处理技术领域。本发明包括回转窑、窑尾烟室和窑尾预热器；窑尾烟室上侧部开设有废气开孔；废气开孔内壁连接有引风管；引风管末端连接有旁路放风余热锅炉；窑尾预热器包括分解炉和多级旋风筒；多级旋风筒连接有窑尾SP余热锅炉；窑尾SP余热锅炉连接有篦冷机；回转窑中窑尾烟室的进料口连接窑尾预热器的出料口；窑尾预热器废气出口连接窑尾SP余热锅炉。本发明通过引风管、旁路放风余热锅炉、多级旋风筒、窑尾SP余热锅炉和篦冷机的作用，便于对锅炉换热过程中烟气进行降尘和收尘，避免烟气烟尘对窑尾余热锅炉的运行造成影响，而且能节省能耗以及保证窑尾SP余热锅炉运行稳定。
