For 1.0MPa pressure, 180 DEG C, quantity of steam 2t/h.This top pressure power generation system is installed at user at this time, specific implementation step is such as
Under:
1, starting Shi Xiantong steam carries out heating coil, and opens drain valve 3, and moisture in pipeline is discharged；
2, by the No.1 electric check valve 5 of regulating system, so that steam enters spiral case 14 by air inlet pipe；
3, steam enters running wheel 16 through jet blade channel 15, and expansion work makes the rotation of impeller 16 to export machinery
Function, drives generator amature rotation and cutting magnetic induction line produces electricl energy；
4, the No.1 electric press regulating valve 2 and No. two electric press regulating valves 9 of regulating system guarantees 8 front and back of turbo-expander
Stable pressure difference；
5, the electric flow control valve 6 of regulating system, meets the power demand of user；
6, when 8 failure of turbo-expander, No. two electric check valves 7 on emergency stop bypass duct 23 are opened, close main road pipeline 22
On No.1 electric check valve 5, emergency shutdown.
Supplier, that is, vapor pressure user side 1 steam is conveyed to turbo-expander 8 by jet chimney 21, turbine is swollen
Swollen machine 8 drives the rotation acting of generator 11, and interior by steam can be converted to electric energy, use on the spot for low vapor pressure user side 13
Or power grid is conveyed to by grid-connection cabinet, the energy utilization rate and economy of system can be increased substantially.
It is any to be familiar with although the present invention is disclosed as above with embodiment, its protection scope being not intended to limit the invention
The technical staff of this technology changes and retouches made without departing from the spirit and scope of the invention, should belong to this hair
Bright protection scope.
