The utility model relates to a 15MW supercritical CO2 axial flow back pressure type turbine with air entering through a volute, and belongs to the technical field of power generation. The problem that a supercritical CO2 turbine power generation technology is not commercially operated is solved. Comprising a front bearing box, an air cylinder, a pressure balance pipe, sealing pieces, a rear bearing box and a rotor, the two ends of the air cylinder are connected with the front bearing box and the rear bearing box respectively, the rotor is installed in the air cylinder, the two ends of the rotor are connected with the front bearing box and the rear bearing box respectively, and the rotor and the air cylinder are sealed through the sealing pieces; an exhaust cavity is formed in the rear portion of the air cylinder, and an air inlet cavity is formed in the front portion of the air cylinder and is of a volute structure. The power is improved, the structure is ingenious and reasonable, and commercial operation is
