Abstract

PURPOSE:To minimize decrease of concentration ability of the collected apparatus during breakage of an airtight container by separating it into a plurality of air sealed cabins by airtight bridge walls and connecting with short pipes between the rotary electric machines. CONSTITUTION:Rotary electric machines 1 and connecting pipes 2 and 3 which provide an airtight flow passage between the machines 1 are housed within an airtight container 4. The machines 1 are respectively attached to the bottom of the container 4, and the connecting pipes 2 and 3 are connected to a hole passing through the cabin with airtight manner by giving flexibility to part of them. The pipe 3 connecting between the machines 1 and the pipe 2 constitute relatively flexible pipes. The machines 1 which belong to a different condensing stage are housed in the respective air sealed cabin separated by a air tight bridge wall 6 within the container 4, and each of the rotary electric apparatus group is connected in cascaded piping.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of the Invention] The present invention relates to a cascade configuration of multiple rotating electric machines.

[Technical background of the invention and its problems] Conventionally, in a gas processing device for concentrating gas, a large number of rotating electric machines are connected in a cascade pipe, and gas is passed through each rotating electric machine to achieve separation based on the mass difference of 1. Is going. Furthermore, the rotating electric machine and cascade piping have an airtight structure that maintains a low pressure of 1.

Even if a small crack occurs due to a malfunction of the rotating electric machine, the atmosphere will flow into the rotating electric machine, which is maintained at a low pressure, and the machine will immediately be unable to rotate normally, causing great damage.

[Purpose of the invention]

The present invention provides a means for preventing such damage and minimizing deterioration in device performance.

[Summary of the invention]

The present invention divides the inside of an airtight container housing a group of rotating electric machines into a plurality of airtight chambers by an airtight partition wall, and each group of rotating electric machines in a section is divided into three short pipes (1), two of which are two collection pipes (1) and one (1). Embodiment of the Invention An embodiment of the present invention will be described below with reference to FIG. 1. The rotating electrical machine 1 and the connecting pipes 2.3 are housed in an airtight container 4. The rotating electric machine is attached to the bottom plate of the airtight container, and the connection piping that forms a gas flow path between the rotating electric machines is partially made flexible and is airtightly attached to the container through-hole. In FIG. 1, a branch pipe 3 connecting the rotating electric machine 1 and the main pipe 2 is constructed of a relatively flexible pipe.

If a faulty rotating electrical machine or one of its connecting pipes cracks and the airtightness is broken, the rotating electrical machines connected to the faulty machine will cause a drop in the airtight container, but unlike the inflow of air, rotational movement will not occur. Since there is no disturbance, operation continues as usual, and the pressure inside the container and the gas pressure soon reach equilibrium.

If such a failure were to occur in rotating electric machines belonging to stages with different enrichment levels, gases with different concentrations would be mixed, which could significantly reduce the enrichment performance of the device. An example of this countermeasure is shown in FIG. A group of rotating electric machines to which different concentration stages 1 belong is stored in an airtight chamber 1allbllc11d divided by an airtight partition wall 6 in an airtight container 4.
Each rotating electrical machine group is connected to a cascade piping as shown in FIG. 3. With such a configuration, direct gas mixing between the crotches due to a failure can be prevented, so a group of multiple stages of rotating electric machines can be housed in the same airtight container. Therefore, the installation area of the group of rotating electric machines can be reduced compared to the case where f airtight containers are prepared for each stage, and the manufacturing cost of the containers can also be reduced.

〔Effect of the invention〕

Since the present invention can minimize the deterioration of the concentration performance of the device due to airtight breakage, it greatly contributes to the economical efficiency and reliability of the device composed of a large number of rotating electric machines.
