Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a compression device having a compact package structure using an outer jacket of a gas cooler.

[Conventional technology]

Conventionally, a gas cooler such as air, which is an accessory of a centrifugal compressor,
The lubricating oil tank and the blast silencer were separately installed on the base plate, and the blast silencer was placed separately in a separate position.

That is, as shown in FIG. 4, the lubricating oil tank 07 and discharge are provided to the coolers 04, 05, 06 of the compressed air (gas) from the first-stage compressor 01, the second-stage compressor 02, and the third-stage compressor 03. The wind silencer 08 was installed separately, and the blowout silencer 08 was installed at a remote position.

[Problems to be solved by the device]

In the conventional centrifugal compressor described above, a cylinder type pipe (steel pipe) is usually used as an outer jacket of the gas cooler cylinder and the blow-off silencer because of the internal pressure condition, but a lubricating oil tank is separately installed together with them. Therefore, the installation space is large and the installation cost is high.

An object of the present invention is to solve such problems and to provide a compression device which has a low construction cost and a small installation space.

[Means for Solving the Problems]

The present invention relates to a compressor in which a jacket of an air or other gas cooler is extended, a lubricating oil tank and / or a blow silencer is incorporated in the extension, and a compressor and a drive motor are installed in the gas cooler jacket. It is a thing.

[Action]

In the present invention, a lubricating oil tank and / or a blow-off silencer is incorporated in the extension of the gas cooler jacket, and a compressor and a drive motor are installed in the gas cooler jacket, and the entire apparatus is packaged. It is compactly organized. Therefore, the installation space and installation man-hours of the compression device are reduced, and the weight of the entire device is reduced, which enables cost reduction.

Further, with the above configuration, the pipe between the compressor and the blow-off silencer can be shortened, and the weight is reduced.

〔Example〕

An embodiment of the present invention will be described with reference to FIGS.

4, 5 and 6 are the first ones each having a jacket of a cylindrical pipe.
The second, third and third stage air coolers (intercoolers) which are extensions 4'of the jacket of the first stage air cooler 4.
Lubricating oil tanks are incorporated therein, and blowout silencers 8 and 7 are incorporated into extensions 5'and 6'of outer jackets of the second and third stage air coolers 5 and 6, respectively.

Reference numerals 1, 2, and 3 denote first-stage, second-stage, and third centrifugal compressors, respectively. , 5 and 6 are mounted on the base plate 11 attached to the outer jacket, and the base plate 11 and the support plate
It is installed on the jacket of the air cooling units 4, 5 and 6 via 12, 12. Also, 13, 13 are base plates which are arranged at intervals and which are attached to the extension parts 4 ', 5', 6'of the jackets of the air coolers 4, 5, 6 by a pair of support plates 14, 14. A drive motor 10 is attached to the base plates 13 and 13, and the drive motor 10 extends through the base plates 13 and 13 and the support plates 14 and 14 to extend portions 4'and 5'of the outer jacket of the air cooler. , 6 '.

As shown by the arrow in FIG. 1, the air enters the first-stage centrifugal compressor 1 and is compressed, and then enters the first-stage air cooler 4 to be cooled. 2, the second-stage air cooler 5, the third-stage centrifugal compressor 3 and the third-stage air compressor 6 are compressed and cooled and sent to a factory or the like as shown by an arrow a in FIG. Used and used.

On the other hand, a part of the compressed and cooled air is released by the blowout silencer 7
The noise is reduced when passing through the zigzag passage formed in the silencer 7 as shown in FIG. 1, and is introduced into the silencer 8 from the silencer 7 and similarly passes through the zigzag passage. In this case, the noise is further reduced and is emitted into the atmosphere.

In this embodiment, as described above, the lubricating oil tank 9 and the blow-off silencers 8 and 7 are incorporated in the extensions 4 ', 5'and 6'of the jackets of the air coolers 4, 5 and 6, respectively. Further, the centrifugal compressors 1, 2, 3 and the drive motor 10 are the air coolers 4,
Since it is installed in the jackets (including the extension part) of 5 and 6, the entire compression device is packaged and made compact.

For this reason, the installation space and installation man-hours of the device are reduced, and the weight thereof is reduced, and the cost can be reduced.

Further, by incorporating the blow-off silencer into the outer extension of the air cooler, the piping between the centrifugal compression and the blow-off silencer can be shortened compared to the case where this is installed separately,
The weight can be reduced.

Furthermore, in the present embodiment, since the blow-off silencer is of the double type in which it is incorporated in the extension portions 5 ', 6'of the jackets of the air coolers 5, 6, it is possible to achieve low noise. You can

In addition, although the above-mentioned embodiment relates to a compression device using a three-stage centrifugal compressor, the present invention can be applied to a single-stage or a multi-stage other than three-stage compressor. The type is not limited to the centrifugal compressor. Further, the jacket of the gas cooler is not limited to the circular cross section, and a cross section having an appropriate shape can be adopted.

[Effect of device]

As described above, according to the present invention, by packaging the compression device, the installation space and the installation man-hour can be reduced as compared with the conventional compression device, and the packaging of the device and the compressor and the release can be performed. By shortening the piping between the wind silencer and the wind silencer, the weight can be reduced and the cost can be reduced.
