Rotary kiln waste heat recycling system

The utility model relates to a rotary kiln waste heat recycling system and belongs to the technical field of waste heat recycling. The rotary kiln waste heat recycling system solves problems of severe environment pollution caused by high-temperature flue gas and energy waste and mainly comprises a boiler, an induced draft fan and a chimney which are connected by a flue pipe, a waste heat recoverer and a superconducting heat pipe are arranged between the boiler and the induced draft fan and supported and fixed through a support A and a support B respectively, a blow-off pipe and a water inlet pipe A are arranged in front of and at back of the waste heat recoverer, a pressure gauge, a safety valve and a steam outlet pipe are arranged at the top of the waste heat recoverer, a water outlet pipe is arranged at the top of the superconducting heat pipe, and a water inlet pipe B is arranged at back of the superconducting heat pipe. The rotary kiln waste heat recycling system is mainly used for waste heat utilization
