The flue gas waste heat recycling system of the vertical carbonization furnace provided by the embodiment of the utility model is described in detail by a specific embodiment and an application scene thereof with reference to the accompanying drawings.
As shown in fig. 1, an embodiment of the present utility model provides a vertical carbonization furnace flue gas waste heat recycling system, which includes a vertical carbonization furnace 110, a flue gas combustion device 120, and a first flue gas pipe 130.
The vertical carbonization furnace 110 comprises a furnace wall 111, a preheating section 112, a supplementary carbonization section 113, an activation section 114, a cooling section 115 and a discharge section 116.

The flue gas generated by the vertical carbonization furnace 110 has combustibility and can be recycled. The vertical carbonization furnace 110 is provided with an air inlet channel 110a and an air outlet channel 110b, and the air inlet channel 110a and the air outlet channel 110b can respectively allow flue gas to enter the vertical carbonization furnace 100 and be discharged out of the vertical carbonization furnace 110. The flue gas combustion device 120 is disposed in the air inlet channel 110a, and before the flue gas enters the vertical carbonization furnace 110, the flue gas combustion device 120 can fully burn the flue gas to supplement heat to the vertical carbonization furnace 110. The outlet channel 110b communicates with the flue gas combustion device 120 via a first flue gas duct 130.
