Zusammenfassung:	The utility model relates to an energy-saving system for waste heat re-use of a power plant, which belongs to the technical field of energy saving, and comprises a compressor, a steam turbine, an evaporator, a condenser, a steam and water heat exchanger and relevant pipelines, wherein the evaporator and the condenser are connected with each other through the pipelines to form a pipeline loop, and the compressor and a throttle valve are connected onto the pipeline loop in series; the compressor is connected with the steam turbine, and the steam turbine is connected with the steam and water heat exchanger; and the steam and water heat exchanger is also connected with the condenser. In the energy-saving system, exhaust steam resources in industry are fully utilized, and electric energy is not used in the whole process, so the energy is obviously saved; and two-stage heating is carried out, the exhaust steam energy of 100% is utilized, and warm water of 70 to 80 DEG C can be eventually supplied to users.
