が知られている。A gas separation device consisting of a cylindrical container that incorporates a fiber bundle assembly formed from hollow fibers with conventional gas separation performance, and is provided with a raw gas inlet, a permeated gas outlet, and an unpermeated gas outlet.

性能が充分に発揮されないという問題があった。However, in conventional gas separation equipment, the raw material gas (mixed gas) supplied into the equipment from the raw material gas supply port is
Gas tends to flow in a part of the device where the yarn bundle is housed, especially around the periphery of the yarn bundle and outside the yarn bundle, that is, along the outside along the periphery of the yarn bundle, and conversely, near the center of the yarn bundle, gas flows easily. stagnation was likely to occur, and it could not be said that the permeation performance inherent to the hollow fibers was fully demonstrated. In this way, when supplying raw material gas to a gas separation device, if there are parts where gas flows easily and parts where gas stagnates, it is difficult to bring the raw material gas into effective contact with the surface of the hollow fiber. Moreover, in areas where gas easily flows, more raw material gas is supplied than the amount that can be processed by the hollow fiber, and as a result, specific gas components in the raw material gas are discharged without being sufficiently separated. On the other hand, in the areas where gas stagnates, the concentration of gas components with low permeability gradually increases, causing the problem that the gas separation performance inherent to Kento, which is made of hollow fibers, cannot be fully demonstrated.
従って、本発明の目的は、原料ガスを中空糸からなる県

are arranged in the circumferential direction of the yarn bundle 5. Note that the hole 10 is not limited to a round shape, but may have any shape such as a rectangular shape as shown in FIG. 5, or an elliptical shape (not shown). A slit 10a as shown in the figure may be provided, and the holes 10 do not necessarily have to be arranged in one row at one location, but may be arranged on two sides and alternately shifted in position, as shown in FIG. Further, the holes 10 may be formed at two or more sides, and the number of holes 10 is not limited to three, but may be one or two, or in some cases four or more. There may be.
前記制限壁９は、上記フィルム状物ｆ８の孔ｌＯから後
述の固化性物質を注入することにより、形成することが
できるものであり、第３図のＡ−Ａ′断面における注入
後の固化性物質（制限壁９）の形状を第４図に模式的に
示した（第４図では糸束５を省略しである）。The limiting wall 9 can be formed by injecting a solidifying substance, which will be described later, from the hole lO of the film-like material f8, and the solidifying property after injection in the A-A' cross section of FIG. The shape of the substance (limiting wall 9) is schematically shown in FIG. 4 (the yarn bundle 5 is omitted in FIG. 4).
上記制限壁９は、上記糸束５の周囲全体に亘ってその外

しく、その際、固化性物質がある程度の深さ迄、例えば
、外周部より糸束５の半径の５％〜６０％、好ましくは
１０％〜５０％の内部まで浸透していてもよい。It is preferable that the restricting wall 9 is in close contact with the outer peripheral part of the yarn bundle 5 over the entire periphery of the yarn bundle 5 in order to restrict the gas flow. , it may penetrate 5% to 60%, preferably 10% to 50% of the radius of the yarn bundle 5 from the outer periphery.
また、上記制限壁９は、上記糸束５の長手方向に少なく

ことができる。Further, it is effective if the restriction wall 9 is installed at at least one location in the longitudinal direction of the yarn bundle 5, but as in the above embodiment, the restriction wall 9 is installed on the side of the raw material gas inlet 1, at the central portion, and at the unpermeated gas exhaust side. By installing it at three locations on the exit 3 side, the effect can be further enhanced. However, the installation location is not limited to the above, and may be changed as appropriate depending on the purpose, for example, 50 mm to 1000+ in the longitudinal direction of the yarn bundle 5
A preferable range is to install at fog intervals.
更に、上記制限壁９を形成するための固化性物質として

入時における粘度が低すぎる場合は、糸束５の内部まで
浸入し過ぎるため、該糸束５の外周部に制限壁９を形成
することが困難であり、逆に粘度が高すぎる場合は、注
入する作業自体が困難であるため好ましくない。Further, the solidifying substance for forming the limiting wall 9 is not particularly limited, and may be a viscous liquid (for example, a viscosity of several tens of poise to several thousand poise), grease, or paste at the time of injection. Various substances can be used as long as they solidify to the extent that they can maintain their original shape after injection, even if the raw material gas is supplied, such as reactive silicone rubber, polyurethane resin, or Examples include epoxy resin. Note that if the viscosity of the solidifying substance is too low when injected, it will penetrate too far into the inside of the yarn bundle 5, making it difficult to form the restricting wall 9 on the outer periphery of the yarn bundle 5. If is too high, the injection process itself becomes difficult, which is not preferable.
また、上記固化性物質は、フィルム状物質８と接着性を
有している方が密着状態を維持するために好ましい、し
かし、接着性がないが又は低い固化性物質であってもよ

密着状態を維持することができる。In addition, it is preferable that the solidifying substance has adhesive properties with the film-like substance 8 in order to maintain the adhesion state, but it is also possible to use a solidifying substance that does not have or has low adhesive properties. In case, the solidifying substance is placed in the hole 1 of the film material 8.
By injecting the solidifying substance from 0 to the inside and simultaneously heaping up the solidifying substance on the outside and solidifying in that state, the state of close contact between the film-like substance 8 and the solidifying substance constituting the control wall 9 is maintained. Can be done.
更に、上記固化性物質を注入する場合は、必要に応じて

減少する割合を少なくすることができる利点がある。Furthermore, when injecting the above-mentioned solidifying substance, if necessary, tie the thread bundle portion at the position where the solidifying substance is to be injected with string or thread to reduce its diameter. It is also possible to inject the solidifying substance after forming a space between the outer periphery of the material and the outer periphery of the material. In this case, there is an advantage that the rate at which the effective membrane area decreases due to the membrane surface of the hollow fiber being covered with a solidifying substance can be reduced.

離が達成される。In the embodiment shown in FIG. 1, when the raw material gas is supplied through the raw material gas inlet 1, the supplied raw material gas comes into contact with the yarn bundle 5 housed in the cylindrical container 4 and discharges unpermeated gas. It flows in the direction of outlet 3. Through the above-mentioned contact of the raw material gas, a specific gas component selectively permeates the hollow fiber 5a, and the gas is supplied as a permeated gas from the permeated gas outlet 2 to other equipment (not shown), and the remaining unpermeated gas is The unpermeated gas is discharged from the discharge port 3. As a result, separation of specific gas components is achieved.
