Abstract

The invention discloses an integrated expansion machine for expansion power generation. The integrated expansion machine for expansion power generation is simple and compact in structure and high in overall efficiency. The integrated expansion machine for expansion power generation comprises a turbine blower inlet casing, a high-speed generator shell and an exhaust blower inlet casing arranged sequentially. The high-speed generator shell comprises a high-speed generator outer shell and a high-speed generator inner shell; a turbine exhaust flow channel is formed between the high-speed generatorouter shell and the high-speed generator inner shell, and communicates with a turbine exhaust port; the high-speed generator inner shell partially stretches into the exhaust blower inlet casing; an outlet flow channel is formed between the high-speed generator inner shell and the exhaust blower inlet casing; an exhaust gas exhaust port is formed in one end, deviated from the high-speed generatorinner shell, of the exhaust blower inlet casing; a high-speed shaft is arranged in the high-speed generator inner shell through a magnetic levitation type radial bearing; and an axial flow fan is arranged at one end, corresponding to the exhaust port, of the high-speed shaft and is used for guiding part of exhaust gas at the turbine exhaust port into the high-speed generator inner shell so as to cool.

Description

Technical field [0001] The invention relates to the technical field of organic Rankine cycle (ORC) power generation, in particular to an integrated high-speed expander for expansion and power generation. Background technique [0002] In the field of organic Rankine cycle (ORC) power generation, the efficiency of the organic working fluid expander has a greater impact on the system efficiency, and increasing the efficiency of the expander can effectively improve the system efficiency. For conventional organic working medium expansion units (that is, the expander drives the generator to generate electricity through gearbox deceleration after the work is done), from the working medium drives the turbine to do the work to the generator output electric energy, the loss of the intake and exhaust shells and the expander bearings in the process Loss, mechanical seal loss, gearbox loss, coupling loss, etc., reduce the efficiency of the whole machine by about 6% to 12%, which is very unfav...
