The invention belongs to the technical field of environmental protection and industrial waste treatment and particularly relates to a high-efficiency melting and incineration device for industrial waste salt. The high-efficiency melting and incineration device for industrial waste salt comprises a melting incinerator body, a waste heat recovery device, a burner A, a burner B, a combustion air pipeline A, a combustion air pipeline B, a flue gas pipeline, a blower, an induced draft fan, an electric control valve, a lifting feeder, a furnace bottom transmission mechanism and a transmission discharging device. According to the high-efficiency melting and incineration device for industrial waste salt, toxic organic compounds in secondary high-temperature incineration flue gas are utilized, andthe waste heat recovery device is utilized, so that the flue gas temperature is reduced, combustion-supporting air is preheated, and meanwhile the effects of protecting the environment and improving the thermal efficiency of a furnace can be achieved.
