Zusammenfassung:	The utility model discloses a device for calcining lime by using flue ash, which comprises a blanking assembly and a coal bunker assembly which are connected through a closed pipeline, and further comprises a nitrogen conveying assembly, a nitrogen storage tank assembly and a nitrogen recovery assembly, the nitrogen conveying assembly is connected with the nitrogen storage tank assembly, the nitrogen storage tank assembly is connected with the discharging assembly, and the nitrogen recycling assembly is connected with the coal bunker assembly. The nitrogen conveying assembly, the nitrogen storage tank assembly, the nitrogen recycling assembly, the discharging assembly and the coal bunker assembly are connected through closed pipelines. The flue dust is used for the lime calcining device and uses a PLC program to control the flow. Nitrogen is adopted as a power source to convey flue ash, the phenomenon that the flue ash explodes in the transportation process is avoided, the flue ash is conveyed through the clo
