The invention relates to the technical field of waste heat recovery, and discloses a waste heat recovery system, in the waste heat recovery system, a preheater and an evaporator are respectively located on respective corresponding working medium circulation paths and are both located between a corresponding liquid storage container and an expansion machine; air is compressed through the first-stage air compressor, one part of the preheater is used for exchanging heat with inlet air behind the first-stage air compressor, heat of the inlet air behind the first-stage air compressor is recycled through a working medium passing through the part of the preheater, and the air subjected to heat exchange and cooling enters the second-stage air compressor to be compressed; the other part of the preheater is used for exchanging heat with inlet air behind the second-stage air compressor, the heat of the inlet air behind the second-stage air compressor is recovered by a working medium passing through the preheater, and th
