As shown in Figure 1, a kind of ORC power generator comprising turbo-expander and generator integral type unit 1, evaporator
2, working medium pump 3 and condenser 4.Wherein, turbo-expander and generator integral type unit 1 may be simply referred to as turbine expansion power generation integrated
Machine, power output and power generation part as the ORC power generator.As shown in Fig. 2, the turbo-expander and generator one
The bearing 102 at 101 both ends of main shaft is magnetic bearing on generator in formula unit 1.Magnetic bearing is a kind of novel high-performance bearing, with biography
System ball bearing, sliding bearing and filmatic bearing are compared, and Mechanical Contact is not present in magnetic bearing, and rotor can achieve very high fortune
Rotary speed has many advantages, such as that mechanical wear is small, low energy consumption, noise is small, the service life is long, is not necessarily to lubrication, without oily pollution, to can be improved
The generating efficiency of the ORC power generator.
In addition, the generator in the turbo-expander and generator integral type unit 1 is preferably no-brush synchronous generator.
No-brush synchronous generator is high-efficient, and motor itself is lost without excitation loss and carbon brush, eliminates multi-stage speed-reducing consumption, integrated power-saving
Rate is up to 20%~60%, and high reliablity, stability is good, and adaptable, maintenance is simple.
Evaporator 2 is connected by pipeline with turbo-expander in the turbo-expander and generator integral type unit 1.It should
