Abstract

PURPOSE:To speedily replace a gas without consuming an objective gas, by a method wherein a rubber balloon form bag is inserted into a gas holder, is inflated, and a gas is charged under pressure into a gap between the holder and the bag. CONSTITUTION:When the gas holder 4 is fitted with air at the atmospheric pressure, the rubber balloon form bag 6 is inserted into the holder 4 through an upper flange 5, ON-OFF valves V1-V4 are closed, a valve V5 is opened, and valves V6-V8 for a purger system are closed. Next, the valves V1, V2, V6 are opened, the objective gas is fed into the bag 6 at a pressure slightly higher than the atmospheric pressure to inflate the bag 6, and an amount of air in the holder 4 corresponding to the volume of the inflation quantity is purged through a purging pipe 3. When the bag 6 comes into contact with the inside surface of the holder 4, the valves V1, V5, V6 are closed, the valves V3, V7, V8 are opened, a blower 7 is operated so that the gas contained in the bag 6 is sucked and fed to a close contact part of the inside wall of the holder 4 and the outside surface of the bag 6 through the valves V2, V3 and a pipe 1 to contract the bag 6, and the purger and the bag 6 are taken out.

なる。Generally, a spherical gas holder is filled with air at atmospheric pressure after an open inspection, so in order to reuse the spherical gas holder, it is necessary to remove the filled air. For this purpose, the gas holder, which has conventionally been filled with air from an atmospheric bulb, is sealed, and the target gas is brought in and out to increase the pressure in the gas holder to above atmospheric pressure. If the pressure of the target gas currently stored in the gas holder is j atmospheres, the target gas is supplied at about S times the amount of the air cover in the gas holder to reduce the mixing ratio of air. Next, the valve of the gas holder is opened to release the mixed gas of the mixed air and the target gas to the outside of the gas holder, and the pressure inside the gas holder is brought to the same pressure as the atmospheric pressure. If the same procedure as described above is repeated while leaving the J gas mixture behind and then sealing the gas holder, the concentration of the target gas in the gas mixture in the gas holder will gradually increase.

な欠点がある。According to the dily-silon method, which repeats the same procedure several times, the target gas supply concentration is adjusted to 90%

However, this requires repeating the above procedure, for example, about 10 times, which wastes the target gas equivalent to 50 times the volume of the gas holder, and also takes 3 days of work time. There is a major drawback in that it requires more than that.

The main equipment is the same as that in Example 1, but there are some differences in the piping system. At the S-th port, when the gas holder q is filled with air at atmospheric pressure, the deflated rubber balloon-like bag 6 is inserted into the gas holder trough from the upper 7 lunge S, and V3 v V4 * VlO is closed. ,v
5 e Open v9, operate the proac, send air from the proac to the bag 6 through v9 to inflate the bag 6, and release the air in the gas holder corresponding to the expanded volume from the diffusion pipe J. dissipate into the atmosphere. The bag 6 gradually becomes larger, and as shown in FIG. 6, it completely fills the inner tank of the gas holder pavilion, so that the bag 6 is completely in close contact with the inner wall of the gas holder pavilion. Next, close V5 * Vg, stop the operation of proar 7, open VLO and inlet pipe/V3, and then supply the target gas from inlet pipe l to the inner wall of the gas holder bow and the bag 6. feed into the contact area. A volume of air corresponding to the volume of the target gas introduced from inside the bag 6 passes through the VIO and is dissipated into the atmosphere, and the bag 6 completely deflates through the state shown in FIG. 7, and from then on, As shown in the figure, the air remaining in the gas holder is completely replaced by the target gas through the same operations as in the first embodiment.

For example, there is no problem even if it is cylindrical, but in this case,
The shape of the rubber balloon-like bag to be inserted may be cylindrical. For example, a rubber balloon-shaped bag for lθθOm3 gas holder has a thickness of
It weighs about the same as J9. This bag can also be inserted from the bottom of the gas holder. Further, in the above embodiment, an example was described in which the rubber balloon-shaped bag was charged from above the tank, but it is of course possible to insert the rubber balloon-shaped bag from below the tank.
