BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas turbine power generator suitable for use where installation area is limited.

0002

[Prior Art] In a conventional gas turbine power generation system, the gas turbine, reducer, and generator are all horizontal, and the gas turbine, reducer, and generator are installed on the same floor at intervals. are doing.

0003

[Problem to be solved by the invention] However, in order to install a horizontal gas turbine, reducer, and generator on the same floor,
There is a problem in that it requires a large site area.

[0004] The present invention has been made in view of the above-mentioned circumstances, with the object of making it possible to install a gas turbine power generation device in a narrow area.

[0005]

[Means for Solving the Problems] In the present invention, a vertical gas turbine and a horizontal or vertical generator are vertically spaced apart from each other.

[0006]

[Operation] The generator is driven by the gas turbine to generate electricity.

[0007] Since the vertical gas turbine and the vertical or horizontal generator are installed vertically apart from each other, it is possible to reduce the area on which the equipment is installed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows an embodiment of the present invention, in which 1 is a base plate installed on a floor 2, 3 is a soundproof enclosure installed upright on the base plate 1, 4 is a second floor surface of the soundproof enclosure 3, and 5 is a soundproof enclosure installed on the baseboard 1. 6 is a vertical gas turbine mounted on the gas turbine support 5, and 7 is installed on the base plate 1 and is driven by the gas turbine 6. A speed reducer 8 is a horizontal generator installed on the base plate 1 and connected to the speed reducer 7 via a coupling 9. Reference numeral 10 denotes an intake duct with a silencer installed to be located outside the second floor surface 4 of the soundproof enclosure 3;
1 is an intake chamber installed in the ceiling of the first floor of the soundproof enclosure 3 in order to introduce combustion air 12 taken in from the outside through an intake duct 10 with a silencer into the gas turbine 6;
13 is a diffuser that penetrates the second floor ceiling of the soundproof enclosure 3 and protrudes to the outside in order to discharge the turbine exhaust gas 14 from the gas turbine 6; 15 is the diffuser 1;
18 is an exhaust duct for guiding the turbine exhaust gas 14 discharged from 3 to a flue 17 via a muffler 16; 18 is a reducer 7;
and a ventilation intake duct with a silencer provided to the outside of the second floor surface 4 of the soundproof enclosure 3 so as to introduce ventilation air 26 into the space 19 above the base plate 1 where the generator 8 is installed;
Reference numeral 20 denotes a ventilation fan installed on the ceiling of the top floor of the soundproof enclosure 3 so as to exhaust the ventilation air 26 that has risen through the space 19 and the space 21 on the second floor of the soundproof enclosure 3 to the outside, and 22 a ventilation fan. A ventilation exhaust duct with a silencer 27 exhausts air from the fan 20, 23 is the base plate 1
Tanks for lubricating oil for each device installed in the section, 24 are stairs, 2
5 is the entrance.

[0010] In the above-mentioned gas turbine power generation device, combustion air 12 is introduced into the gas turbine 6 from the intake duct 10 with a muffler through the intake chamber 11 by driving the compressor of the gas turbine 6. air 12
is used for fuel combustion, and the combustion gas obtained by the fuel combustion drives a compressor through the turbine body of the gas turbine 6, and is sent as turbine exhaust gas 14 to a flue via a diffuser 13, an exhaust duct 15, and a muffler 16. 17 and is discharged from the flue 17 to the atmosphere.

The gas turbine 6 also drives a generator 8 via a reduction gear 7 to generate electricity.

Furthermore, during the above-mentioned power generation, the ventilation air 26 is introduced into the space 19 from the ventilation intake duct 18 with a silencer,
It flows from the space 19 to the space 21, and is exhausted from these spaces 19, 21 to the outside via the ventilation exhaust duct 22 with a muffler by the ventilation fan 20, whereby the spaces 19, 21
Ventilation is performed in one pass.

In the above embodiment, since the reducer 7 and the horizontal generator 8 are installed under the vertical gas turbine 6,
The site area where the equipment is installed can be reduced. Furthermore, in this embodiment, the speed reducer 7 and the generator 8 are arranged horizontally on the base plate 1, so this embodiment is suitable for cases where there is a limit on the height of the device.

FIG. 2 shows another embodiment of the present invention. In this embodiment, not only the gas turbine 6 but also the reducer 7 and the generator 8 are used.
The generator 8 is mounted on the base plate 1, the reducer 7 is mounted on the second floor floor 4a of the soundproof enclosure 3, and the soundproof enclosure 3 is vertically shaped.
Gas turbines 6 are respectively installed on gas turbine support stands 5 erected on the floor surface 4b of the third floor.

Gas turbine 6, reducer 7 and generator 8
Since they are all vertical, the installation area can be made even smaller than in the embodiment shown in FIG.

In the figure, the same reference numerals as those shown in FIG. 1 are given the same reference numerals.

[0017] In the embodiments of the present invention, the case where the gas turbine, speed reducer, and generator are installed in a soundproof enclosure has been described, but it is also possible to install them on a frame, and depending on the rotational speed of the gas turbine. It goes without saying that the reduction gear does not need to be installed, and that various other changes can be made without departing from the gist of the present invention.

[0018]

[Effects of the Invention] According to the gas turbine power generation device of the present invention, the site area on which the device is installed can be small, and the site can be used effectively.
