Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a centrifugal separator in which a plurality of centrifuges are arranged.

(Prior Art) As is well known, a centrifugal separator in which a plurality of centrifuges are arranged is constructed as shown in FIG. 3, for example. In the figure, reference numeral 1 denotes a centrifugal separator that houses a rotating body and a gas supply/exhaust part inside, and the upper part of each is closed with a lid 3. The lid 3 is provided with an introduction pipe 5 for introducing gas from the gas piping 4 to be separated into the rotating barrel of each centrifugal separator 1, and extracts the separated heavy gas component and light gas component from the rotating barrel, respectively. Extraction pipes 8 and 9 are provided to allow the water to flow out into the pipes 6 and 7.

Gas separation in the centrifugal separator configured as described above is performed by centrifuging the gas to be separated which is introduced into the rotary drum from the pipe 4 through the introduction pipe 5 and then extracted through the respective extraction pipes 8 and 9. .7 will be collected.

Normally, in order to obtain a predetermined amount of separated heavy gas components and light gas components, multiple centrifugal separators are connected by a gas pipe 4 to be separated and a pipe 6.7 for heavy gas components and light gas components. is configured.

In the above centrifugal separator, a plurality of centrifuges 1. Multiple inlet tubes from...5. ..., extraction tube 8. ....

It is necessary to connect each of 9, . was requested.

On the other hand, Japanese Unexamined Patent Publication No. 54-158596 describes a centrifugal separator having a configuration as shown in FIG. 4.

This is a through hole 10°11.12 in M3 of centrifuge 1.
are provided, and dust pipes 15 and 16 having openings 13 and 14 are arranged in the upper part of the lid 3 so as to correspond to the through holes 11 and 12 to provide airtightness. It is something that has been set. In addition, a negative pressure chamber 18 is formed by covering the entire body with a cover plate 17, and the gas to be separated is introduced into this negative pressure chamber 18, and the separated heavy gas component,
The light gas components are configured to flow out into gas pipes 15 and 16.

With this structure, since a common gas pipe is provided on the upper surface of the lid 3, the assembly work efficiency is slightly improved.

However, in this configuration, although one lid 3 is provided corresponding to one centrifuge, one through hole 11.
12 and the openings 13.14 of the gas pipes 15.16 must be precisely positioned. Moreover, gas piping 15.1
6 is common to many centrifuges 1, the through holes 11.12 and the openings 13.14 of the gas pipes 15.16 are positioned at multiple locations at the same time, and these connections must be sufficiently airtight. It is difficult to position all the parts with high precision.

Placing gas piping on the top surface of 3 increases the size.In a conventional centrifugal separator with multiple centrifuges installed, as the number of gas piping connections increases, the assembly work becomes complicated and the size increases. I also couldn't avoid masturbation.

The present invention has been made in view of the above circumstances, and its purpose is to provide a centrifugal separator with a simple structure of gas piping for a plurality of centrifuges and good assembly workability.

The centrifugal separator of the present invention is a centrifugal separator in which a plurality of centrifugal separators are arranged to separate a gas to be separated introduced into a centrifugal force field in a rotating drum into a heavy gas component and a light gas component and extract the separated gas. a first lid that commonly blocks the top surface of the centrifugal separators; a groove provided on the top surface of the first lid to form a gas flow path common to the plurality of centrifuges; and a groove that blocks the groove. The second lid is provided with a gas pipe for flowing gas between the inside of the rotary cylinder and the groove.

(Function) In a device configured in this way, even when a large number of centrifugal separators are arranged in a cluster, the upper surfaces of these multiple centrifuges are closed with a common lid, and a groove is formed in this common lid. Since the groove is closed with a separate lid to form a common gas flow path, there is no need to connect piping to each centrifugal separator, and each gas flow path can be secured by simply covering the common lid. It has a simple structure and is easy to assemble.

(Example) An example of the present invention will be described below with reference to the drawings.

Fig. 1 is a cutaway side view showing some essential parts of the centrifugal separator of the present invention, and Fig. 2 shows the same parts as the XX' arrows with the same reference numerals and detailed explanation thereof is omitted. do.

All centrifuges 1 are arranged in multiple centrifuges 1.
A common lid 3 is provided to close the upper part of each centrifuge tlil. This common M3 includes centrifuge 1
Grooves 2a and 2b are formed so that they can communicate with all centrifugal separators 1, depending on the arrangement of the centrifuges 1.

It communicates with the inside of the centrifuge 1 via extraction pipes 8 and 9. and grooves 2a and 2b formed in the lid 3.

2c has its upper surface sealed by another lid 3°, each forming a gas flow path.

Note that the grooves 2a and 2b form gas flow paths.

2C includes a gas supply pipe 201 to be separated and discharge pipes 21 and 22 for discharging separated heavy gas components and light gas components.
is inserted through the lid 3'.

Next, the centrifugal separator having the above configuration will be explained.

The gas to be separated is supplied from a gas piping (not shown) through the supply pipe 20 into the groove 2a serving as a gas flow path. The second gas to be separated is introduced into the rotary barrel through the introduction pipe 5 and centrifugally separated into heavy gas components and light gas components. The centrifuged component gases are extracted through extraction pipes 8.9, collected in grooves 2b and 2c, which serve as respective gas flow paths, and then passed through exhaust pipes 21.22.
The gas then flows out into a separated gas pipe (not shown).

By configuring the centrifugal separator as described above, the complexity of providing a supply pipe 20 and a discharge pipe 21 and 22 for each centrifugal separator 1 and connecting them to each gas pipe is eliminated, and it is directly common to each centrifugal separator 1. The structure is simple and the assembly work efficiency is improved.

In addition, positioning can be easily performed to form a common gas flow path on the top surface of the lid.

Also, M3 has #; #: 2 a , 2 b , 2
In order to form the gas flow path c, a gas flow path with a large volume can also be formed inside the lid 3, thereby increasing the strength of the gas flow path and making it more compact.

[Effects of the Invention] As described in detail above, according to the present invention, the structure of gas piping for a plurality of centrifugal separators is simplified, and assembly workability is improved.
