知られている（例えば、特開昭５６−９１８０２号公報
）。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to gas separation membrane cells. [Prior Art] Conventionally, a gas separation membrane is stacked on a support having air permeability to make the surrounding area airtight. Gas separation membrane cells having an adhesive-sealed structure are known (for example, Japanese Patent Laid-Open No. 56-91802).
しかしながら、気体分離膜の周囲のみを支持体と接着す

ときには気体分離膜の中央部が凸状にふ（らむため、厚
み方向にセルを複数枚積層してモジュールに組み上げた
とき、相対する気体透過膜間′士が接触し、膜が破損す
る恐れがあった。However, in a cell structure in which only the periphery of the gas separation membrane is bonded to the support, the central part of the gas separation membrane swells in a convex shape when the inside of the cell is not under reduced pressure, so multiple cells are formed in the thickness direction. When stacked and assembled into a module, there was a risk that opposing gas permeable membranes would come into contact and damage the membranes.
したがってセル間隔を膜同士が接触しないよう充分広く
取る必要があり、モジュールを小型化できないという問
題点を有していた。Therefore, it is necessary to make the cell interval sufficiently wide so that the membranes do not come into contact with each other, resulting in the problem that the module cannot be miniaturized.
本発明者らは、モジュールを小型化できる気体分離膜セ
ルを得るべく鋭意検討した結果、本発明に到達した。The present inventors have arrived at the present invention as a result of intensive studies aimed at obtaining a gas separation membrane cell that can make the module smaller.

This is a gas separation membrane cell having an outlet for taking out gas.

FIG. 1 shows a perspective view of a gas separation membrane cell according to an embodiment of the present invention, and FIG. 2 shows a cross-sectional view when two cells of FIG. 1 are stacked. Here, (1
) is a gas separation membrane that selectively separates mixed gases, (2) is a gas permeable support that supports the membrane and serves as a flow path for the gas that has passed through the membrane, and (3) is a gas separation membrane that selectively separates mixed gases. An adhesive layer (4) distributed over the entire surface between the cells collects the permeated gas and guides it to the outlet (5). At the same time, when the cells are stacked, a spacer is formed to form a gap for the mixed gas to flow between the cells. The frame member (6) serving as the opening is a sealing material to prevent the mixed gas from directly leaking into the cell without passing through the membrane.
The other two sides where the frame member is not fitted and the joint between the outlet and the frame member are similarly sealed.

As a method for distributing between 2), a coating method or a spray method is usually used. If a coating method is used, the adhesive can be formed into a thread-like, dash-like, dot-like, or net-like shape, and if a spray method is used, adhesive dots can be formed randomly.

（５）まで導くための集気溝を有している。The amount of adhesive adhered to the gas separation membrane (1) is determined by
2) It is desirable that the amount is the minimum amount necessary to prevent it from floating up. If the amount is too large, the gas permeability may be impaired, or if a solvent-based adhesive is used, the gas separation membrane may be damaged by the solvent, while if it is too small, the membrane may easily lift off from the support. Applying the adhesive in the form of a spray is desirable because it makes it easier to uniformly disperse a small amount of adhesive, and even if a solvent-based adhesive is used, the solvent evaporates quickly and does not adversely affect the film. A can of spray glue (for example, 3M Spray Glue 77, which is made by dissolving a rubber-based resin in an easily volatile solvent) is conveniently used for this purpose. The frame member (4) can be made of metal such as aluminum or plastic such as hard PVC, but plastic is preferable because it is easy to process and lightweight.
Molded by extrusion molding, die molding, etc. The frame member has a gas permeable support, a slit for inserting the gas separation membrane, and an air collection groove for guiding the permeate gas collected through the gas permeable support to the outlet (5).
取り出し口（５）は通常アルミ、プラスチック等のパイ
プであり、圧力損失が太き（ならないよう透過気体量に
応じて適切な内径のものを選べばよい。The outlet (5) is usually a pipe made of aluminum, plastic, etc., and should be selected to have an appropriate inner diameter depending on the amount of permeated gas to avoid large pressure loss.
シール材（６）としては、ウレタン、シリコーン等のゴ

に悪影響を及ぼさないことから、好適に用いられる。As the sealing material (6), rubber sealants such as urethane and silicone, hot melt adhesives, and the like are preferably used because they do not have a negative effect on the gas separation membrane.

Connect and reduce the pressure inside the gas separation membrane cell. At the same time, when the mixed gas to be separated is supplied between the cells using a blower fan, etc., the gas fraction i! I membrane (
1) Due to the pressure difference between the front and back surfaces, gas selectively permeates through the membrane and is separated. The permeated gas passes through the breathable support (3)
, through the ventilation groove in the frame member (4) and the outlet (5) to be taken out to the pressure reducing means side. At this time, the gas separation membrane is pressed inward by the pressure difference. On the other hand, when the separation operation is stopped, that is, when the vacuum pump is not operating, no force is applied to the gas separation membrane (1).

On the other hand, in a conventional gas separation membrane cell in which the gas separation membrane and the permeable support are bonded only at the periphery, even if the membrane stretches slightly, the membrane will float away from the support when the separation operation is stopped, and the adjacent gas separation Since the membrane cells were damaged by contact with the surfaces of the membranes facing each other, the separation performance became poor after only a few minutes of operation time compared to the present example. Also,
In order to obtain stable performance as in this example, it was necessary to make the interval between the gas separation membrane cells approximately twice as wide as in this example.

(12) is the bottom plate of the module case, (13) is the top plate of the module case, (14) ) is a column inserted into the opening of each cell and spacer, one end of which is fixed to the bottom plate, and the screw part (14b) at the other end is fitted with a latch (15) to tighten the bottom plate and the top plate. The openings of the cell stack are airtightly connected to each other.

) The sealing material (9) can be of the same construction as in the first embodiment. The spacer (11) can be arbitrarily selected from metal, resin, rubber, etc., but in order not to give a bad impression W on the membrane, it is necessary to contain as little low-molecular substances as plasticizers, etc., and to maintain sealing properties. It is preferable that the material has some degree of flexibility, and a silicone rubber base circa is preferably used as a material suitable for this purpose. Spacers may be glued to the membrane surface to improve airtightness, but airtightness can be easily maintained by alternately stacking rubber spacers and cells and then tightening the bottom plate and top plate from above and below with bolts, etc. . The plates (12) and (13) can be made by bending a metal plate such as aluminum or a resin plate into any shape that suits the usage of the module, rather than just a flat plate, and it is easier to use by plastic injection molding. It can also be shaped. This example differs from the previous example only in the shape of the part for extracting permeated gas from each cell and the method of connecting each cell, but basically operates in the same manner as in the previous example. By adhering with an adhesive layer distributed over the entire area, the same effect as in the previous example was obtained.

。As described above, according to the gas separation membrane cell of the present invention, since the gas separation membrane and the air permeable support are bonded over substantially the entire surface, the sagging of the gas separation membrane while the separation operation is stopped is eliminated. Therefore, the stacking interval of the gas separation membrane cells can be reduced, the size of the module can be reduced to about half that of conventional products, and the performance can be maintained stably for a long period of time.
