Abstract

PURPOSE:To reduce sharply a time required for gas discharging i.e. exhausting, by connecting chambers mutually with pipings. CONSTITUTION:A process-header-piping 5 for connecting separation stages is constituted of two pipings respectively; in regard to the Mth stage, gas is fed from the Nth stage of an upper stage by one piping, and the other piping is used as an outputting piping from itself. Between it and the Lth stage of a lower stage, one of two pipings of the connecting pipings 5 is used to feed the gas to it from the Lth stage and the other one is used as an outputting piping from the Lth stage. For exhausting the gas from all the separation stages and process- header-pipings 4 and 5, the gas is flowed through every insides of chambers 1 by exhausting the gas from the point A because the separation stages and the headers are connected in a communicating relation by the header pipings 6 and 7 used for exhausting.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention utilizes a cascade system in which a chamber containing a plurality of separation elements for separating a mixed gas containing a heavy gas component and a light gas component into each component gas is housed in a horizontally packed arrangement. Relating to a gas separation device connected to.

[Technical background of the invention and its melting point]

Gas separation devices connected in a cascade system have the disadvantage that it takes a considerable amount of time to completely exhaust the gas in the separation stages and piping.

[Purpose of the invention]

The present invention has been made in order to eliminate the above-mentioned drawbacks, and provides a gas separation device that makes it possible to greatly shorten the distance between the rings required for gas discharge, that is, by simply connecting the chambers together with piping. It is in.

[Summary of the invention]

That is, the present invention provides exhaust piping for a separation cascade.
A gas separation device characterized in that the chambers, which are constituent elements of a separation cascade, are connected in series at the separation stage so that the chambers themselves are also used as exhaust piping, and the separation stage itself is also connected with piping in series to improve exhaust performance. It is.

[Embodiments of the invention]

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

In the figure, reference numeral 1 denotes a chamber that accommodates a plurality of separation elements, and this chamber 1 consists of a portion where the separation elements are grouped together, that is, a separation chamber 2 and a space 6 between the separation elements.

Then, each chamber 1 is connected in parallel with a process header piping 4.

In addition, the symbols M, , M,, M, ... in the figure are separation stages (M stages), and N,, N,, N, ... are other separation stages (N stages), It also shows the L stage, etc.

As is well known, each separation stage includes header piping 4 for Proyas,
5 to form a separate cascade.

Therefore, the process header piping 6 that connects the separation stage
are each composed of two pipes, and focusing on the M stage, one pipe is used to supply gas from the upper N stage, and the other pipe serves as the output pipe of the own stage.

Gas is supplied from the L stage to the lower L stage using one of the two connecting pipes 5, and the other pipe serves as the output pipe of the own stage.

Each stage is connected by ladder piping 4 in order to connect the chambers 1 in parallel.

All separation stages are connected to the space 3 of the chamber 1 by exhaust header piping 6, and are connected to the space 3 of the chamber 1.

In the direction of the N stage, it goes up to the exhaust header piping 7 and is connected to the pipe in series in the direction of the parallel direction in the membrane.

In all the connection configurations of the chamber 1 as described above, all separation stages and process header piping 4,
In order to exhaust gas from chamber 5, the separation stage and the header are connected in the above-mentioned communication relationship by exhaust header piping 6 and 7, so if the gas is exhausted from point A shown in the figure, for example, the gas will pass through the inside of all chambers 1. It will flow to

In addition, in the configuration of the present invention, the valves 8 and 9 are as shown by the broken lines in the figure.
You may also connect the chamber via.

In this case, various operation modes can be accommodated by opening and closing the valves 8 and 9, but this does not necessarily have to be installed because of the high cost.

In particular, it is conceivable to install the stage connection valve 8 without installing the valve 9 for the role.

Since the stage connection valves 8 are normally at the same pressure between the stages, they can have the role of preventing a small amount of gas flow even though no gas flow occurs during normal operation.

〔Effect of the invention〕

As explained above, according to the present invention, even if a large space 3 is created in the chamber 1 that must be evacuated in order to accommodate a plurality of separation elements, the air can be evacuated without going through the separation chamber 2 of the chamber 1. Since the separation element can be directly evacuated, the separation element can be evacuated quickly.
