The invention discloses a counter-rotating air compressor and a gas turbine power device with the counter-rotating air compressor. A fan of the counter-rotating air compressor is provided with a rotorblade but provided with no connotative stator blade. An oblique flow impeller is arranged in an inner duct, and located between the rotor blade and a combustion chamber. Blades of the oblique flow impeller are of a large sweepback structure, and wedge structures are formed on the front edges of the blades. Compared with a conventional counter-rotating air compressor and related power devices, therotor blade of the fan is omitted, and large sweepback and wedge design is adopted by the blades of the oblique flow impeller behind the fan correspondingly. Thus, the structure of the counter-rotating air compressor can be simplified, the number of parts can be reduced, the axial size of the counter-rotating air compressor is shortened, and the weight is reduced. 本发明公开种对转压气机及具有该对转压气机的燃气涡轮动力装置，对转压气机的风扇具有转子叶片且不具有内涵静子叶片；斜流叶
