Abstract
The utility model discloses a single-shaft PTA air compressor unit, comprising a steam turbine, a centrifugal compressor, an axial flow compressor and a tail gas turbine which are arranged coaxially. The steam turbine is driven by steam which has pressure of 0.3 MPa, 0.24 MPa and 0.05 MPa and generated by the unit, and the tail gas turbine is driven by tail gas with temperature ranging from 160 DEG C to 180 DEG C and generated by operation of the unit and has an intermediate heating function. The single-shaft PTA air compressor unit is compact in structure, fine in stability and high in reliability, and increases efficiency when running within a wider range. Simultaneously, the air compressor unit is driven by energy generated by a PTA device after being operated, and then does not need external energy, thereby being capable of recycling energy very well.
