ましい。SUMMARY OF THE INVENTION An object of the present invention is to solve these problems and provide a gas adsorption/separation device that is compact, requires less installation space, and reduces noise during operation. [Means for Solving the Problems] The gas adsorption separation device of the present invention has a gas adsorption zone D consisting of the gas adsorption tank A and the adsorbent 11, and a gas regeneration tank B and the gas product tank C described above. Storage zone ■, and pump 13, drive motor 12 and valve 14
In a gas adsorption/separation device that basically consists of an equipment housing zone (1) in which there are 16 to 16, for example, as shown in FIG. A cylindrical space 1, an upper space 2, and a lower space 3 are formed by an intermediate plate 9 between the top plate and the bottom plate that separates the upper and lower parts, and one of the upper space 2 and the cylindrical space 1 is designated as a gas adsorption zone. The other side is a gas storage zone ■
(In the illustrated example, the upper space 2 is the gas adsorption zone, and the cylindrical space 1 is the gas storage zone.) The lower space 3 is the equipment storage zone (2). The cylindrical space 1 serving as the gas storage zone (2) is divided into a gas regeneration tank B and a gas product tank C by a partition plate 18. In addition, the upper space 2 which becomes the gas adsorption zone A is
It is also divided into a plurality of compartments by a partition plate 19. In the example shown in FIG. 2A-C, the double cylinder is a concentric cylinder,
The inner cylinder 5 has substantially the same length as the outer cylinder 6, and the intermediate plate 9
is located at the upper part of the inner cylinder, so that the upper space 2 is located inside the cylindrical space 1. In FIGS. 3A to 3C showing another embodiment, the double tube is a square tube (rectangular cross section), the inner tube 5 is shorter than the outer tube 6, and the intermediate plate 9 is substantially the same as the top plate 7. The structure is such that the upper space 2 covers both the lower space 3 and the cylindrical space 1, and is in contact with the upper end of the inner cylinder. Of course, modifications such as making the double cross section square in the embodiment shown in FIG. 2 or circular in the embodiment shown in FIG. 3 are also possible. In order to increase the gas concentration of the product gas, it is desirable that the capacity of the regeneration tank is at least three times the capacity of the adsorption tank.

得る。The device of the present invention has zones for each function arranged one above the other and is integrated, so it is compact and requires a small installation floor space. In a preferred embodiment in which the capacity of the regeneration tank is three times or more the capacity of the adsorption tank, the efficiency of gas separation is greatly increased, so that the apparatus can be made even more compact. In addition, noise generated from motors, pumps, valves, etc. is doubly blocked by the walls of the container above and around the device, and is attenuated by the bottom plate below, so it is significantly reduced during rest. [Example 1] An apparatus of the present invention having the structure shown in FIGS. 3A to 3C was manufactured, and the noise level during operation was measured. Using 6 Ky of synthetic zeolite 5A as an adsorbent, it was operated under the pressure swing method under the following conditions. Pressure adsorption Adsorption pressure is 0.5! J/criG vacuum desorption Desorption pressure -50CmH1lI cycle
120 seconds Comparing the size and noise with a conventional device with the same capacity (equipment such as a tank and pump arranged independently on a trolley), the following is true. Dimensions Noise (Length x Width x Height) (Hon) Example 300X400X700 5OJX Lower Comparative Example
450 x 450
%, the volume is 50% more compact, and the noise level is also much lower. [Example 2] In the apparatus of the present invention having the structure of Example 1, the oxygen concentration of the product gas was investigated by changing the ratio of the capacity of the regeneration tank to the capacity of the adsorption tank. Adsorbent and operating conditions are as in Example 1.
is the same as Regardless of the amount of product gas generated, it has been confirmed that increasing the ratio of the regeneration tank capacity to the adsorption tank capacity increases the oxygen concentration, and that a sufficient effect can be obtained if the ratio is 3 or more. Ta. The apparatus of the present invention has been explained above using an example in which a molecular sieve is used to adsorb and remove nitrogen from the air to obtain an oxygen-enriched gas, but other adsorbents may also be used. Since the present invention can also be applied to mixed gases, various embodiments are possible. The gas adsorption separation device of the present invention has a high gas separation efficiency of 1 or more, and has low noise. It is therefore of particular interest when applied to oxygen generators, for example for use in oxygen inhalation in hospital rooms, and has many possible uses.
