The annular air flue is arranged between the inner wall 106 and the outer wall 107 of the dry quenching furnace 1 and consists of the inner wall 106, the outer wall 107 and the bracket supports 108, and the flue gas in the annular air flue can enter other devices or equipment through a pipeline 109. In some embodiments of the present disclosure, the other device or apparatus described above may be the second dust remover 101 in the embodiments described below.
In some embodiments of the present disclosure, the dry quenching flue gas treatment system further includes a first interface, a second interface and a feeding port disposed at the top of the dry quenching furnace 1, a third interface and a discharging port disposed at the bottom of the dry quenching furnace 1, a flue gas circulation device, a feeding device 4, a coke discharging device and a coke transporting device 6, wherein:
the flue gas circulating device comprises a second dust remover 101, a waste heat treatment device 102, a third dust remover 103, a second pipeline fan 104 and a heat exchange device 105 which are sequentially connected through a pipeline and sequentially arranged along the direction far away from the first interface, wherein an air inlet of the second dust remover 101 is connected with the first interface through a pipeline, and an air outlet of the heat exchange device 105 is connected with the third interface through a second pipeline 122; one end of the first pipe 121 is connected to the pipe between the second pipe blower 104 and the heat exchange device 105; wherein, the second dust remover 101 can be connected with the annular air flue in the dry quenching furnace 1 through a pipeline 109;
the feeding device 4 is arranged above the dry quenching furnace 1 and feeds materials into the dry quenching furnace 1 through a feeding hole;
the coke discharging device comprises a third pipeline 123, a sealing valve 501 and a coke discharging chute 502, wherein one end of the sealing valve 501 is connected with the discharge hole through the pipeline, the other end of the sealing valve 501 is connected with the coke discharging chute 502, one end of the third pipeline 123 is connected with the second interface, and the other end of the third pipeline 123 is connected with the coke discharging chute 502; the second interface is connected with an air inlet of the annular air passage;
