Abstract

The invention belongs to the technical field of secondary copper smelting, and particularly discloses a secondary copper smelting waste heat recycling device. The regenerated copper smelting waste heat recycling device comprises a shell, one side of the shell is connected with an air inlet pipe, the other side of the shell is connected with an air outlet pipe, and the shell is used for introducing high-temperature flue gas to complete heat exchange and then discharging the flue gas; and the heat exchange fin tube bundle is arranged in the shell and used for heat exchange of the high-temperature flue gas. Under the action of the first flow guide plate, the baffle and the drainage pipe, when flue gas at the gas inlet is adjusted and flue gas fluctuation is large, split-flow adjustment is achieved, long-term high-efficiency energy saving is achieved, meanwhile, high-temperature thick smoke dust is discharged at the moment of secondary copper smelting, the temperature and concentration of flue gas entering the heat exchanger are reduced through split-flow of the drainage pipe, and equipment is prevented from being damaged and blocked; and corrosion of heat exchange elements and shortening of the service life of equipment due to acidic condensate water generated by too low smoke temperature are avoided.
