Environment-friendly sleeve kiln system
The invention provides an environment-friendly sleeve kiln system. The environment-friendly sleeve kiln system comprises a kiln body and a kiln top waste gas pipeline. Wherein the inlet end of the kiln top waste gas pipeline is connected with the top end of the kiln body; the outlet end of the kiln top waste gas pipeline is connected with a cooling branch pipeline and a waste gas branch pipeline; two outlet pipelines are arranged at an outlet of the cooling branch pipeline, one outlet pipeline is connected with an inlet of the driving fan, the other outlet pipeline is connected with an inlet of the kiln bottom cold air mixing valve, and the outlet end of the waste gas branch pipeline is connected with an outlet of the driving extension set. All waste gas in the kiln is discharged through the kiln top waste gas pipeline; through the arrangement of the cooling branch pipeline and the waste gas branch pipeline, about 30% of flue gas at the kiln tail can be cooled and recycled through the cooling branch pipeline, meanwhile, the cooled flue gas is divided into two paths to be conveyed into the kiln body, the amount of air entering the kiln is reduced, and the content of nitric oxide in the flue gas is effectively reduced.
本发明提供了一种环保套筒窑系统，该系统包括：窑本体和窑顶废气管道；其中，所述窑顶废气管道的进口端与所述窑本体的顶端相连接；所述窑顶废气管道的出口端连接有降温分支管路和废气分支管路；所述降温分支管路的出口处设有两个出口管道，其中一个出口管道与所述驱动风机的入口相连接，另一个出口管道与所述窑底掺冷风阀的入口相连接，所述废气分支管路的出口端与驱动分机的出口相连接。本发明通过窑顶废气管道对窑内全部的废气进行排放；通过降温分支管路和废气分支管路的设置，可使得窑尾约30%的烟气通过降温分支管路进行降温回收，同时，将降温后的烟气分两路输送至窑本体内，减少空气进入窑内的风量，有效地降低烟气中的氮氧化物的含量。
