The materials, reagents, methods and apparatuses used in the following embodiments are, unless otherwise specified, all materials, reagents, methods and apparatuses conventional in the art. Those skilled in the art are commercially available.
FIG. 1 is a schematic structural diagram of a comprehensive utilization system for waste heat and flue gas in ore smelting in an optimal scheme. As can be seen from fig. 1, the waste heat flue gas comprehensive utilization system is composed of a light-burning kiln 1, a mixed-burning kiln 2, a waste heat flue gas mixing buffer device 3, an induced draft fan 4, a plurality of drying devices 6, a waste gas treatment device 7, a chimney 8 and a plurality of pipelines for communicating the devices. Wherein, the draught fan 4 is provided with a power supply 5 for providing power for the draught fan. The light-burning kiln 1 is communicated with an air inlet at the top of the waste heat and flue gas mixing and buffering device through a pipeline I11 and extends into the mixing device 31 of the light-burning kiln.
