ートリツジタイプの流体分離装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved hollow fiber membrane fluid separation device. More specifically, the present invention relates to a cartridge-type fluid separation device that is easy to handle and replace, has a large hollow fiber filling degree, and can withstand high-pressure operation for a long period of time.

うになつた。 Hollow fiber fluid separation devices have a large membrane area per unit volume and require less energy for separation than other types of devices, so they are widely used in separation operations such as dialysis, gas separation, reverse osmosis, and ultrafiltration. I started to do that.

い。 A bundle of hollow fibers in which both ends are tied together and the fibers are fixed together with an adhesive without any gaps between them has a wide range of uses because fluid can be supplied into the hollow fibers, compared to a bundle in which only one end is fixed. However, compared to one in which one end is fixed, with this type, the gap between the hollow fiber bundle and the container housing it must be sealed at both ends to prevent leakage or mixing of fluids.
This point has been a major obstacle in creating a cartridge-type device with both ends fixed. Therefore, in the past, a strong core rod was placed in the center of the hollow fiber bundle, and this rod transmitted the necessary force to the sealing part. Both ends of the hollow fiber bundle and the storage container are fixed together and integrated into a single unit, in other words, they are not a cartridge type.

等の欠点がある。Methods such as these have been taken. However, in method 2, the filling rate of the hollow fibers decreases by the amount of the core rod, and in method 2, a particularly strong sheath member must be selected, and if the device becomes long, there is a risk that the seal will be incomplete. With method 1, it is not possible to replace just the membrane unit, so the replacement cost will be high.
There are drawbacks such as.

離装置を内容とする。 The object of the present invention is to provide a hollow fiber fluid separation device that overcomes these drawbacks. That is, the present invention provides a removable cartridge having a structure in which both ends of a bundle consisting of a large number of hollow fiber membranes are fixed together with a sheath that encloses the bundle, and a removable cartridge that houses this and is connected to the hollow part of the hollow fibers. a first fluid outlet and an inlet, and a second fluid outlet through which the first fluid has passed through the hollow fiber membrane, or a second fluid outlet that contacts the first fluid only through the hollow fiber membrane; The fluid separation device comprises a container having an inlet, a sealing part, and a stopper, and the cartridge is fixed to the container by means of fasteners at both ends of the cartridge.

The material may be made of synthetic resin, metal, etc. depending on the purpose. That is, the device of the present invention:
The force necessary for sealing is transmitted only from the fixed parts themselves at both ends of the hollow fiber bundle, and since that force is not transmitted to the sheath, there is no need for a core rod or special sheath, and the hollow fibers are inside the sheath. Since the membrane is highly filled, the membrane area per volume is large. Since the hollow fiber bundle unit is fixed to the storage container with only a stopper, it has the advantage of being cheap and easy to replace.

る。 1 to 3 are cross-sectional schematic diagrams of conventional cartridge-type devices. Each device fixes both ends of the hollow fiber bundle 2 in a cartridge storage container 1 having first and second fluid inlets and outlets 11 and 12 or a first fluid inlet and outlet 11 and a second fluid outlet 12. The structure is such that a cartridge is stored while sealing between the storage container and the cartridge using the fixed portions at both ends. In the apparatus shown in FIG. 1, between the container and the cartridge there are fixed parts 4 and 4'
It is sealed at the tapered part. At the fastening part 4, the forces applied to the tapered part are supported by the tapered part of the container, while at the other end 4' the forces applied to the tapered part have to be supported by the sheath 3. Therefore, the material of the sheath is limited and must be particularly strong and non-compressible. In the device of FIG. 2, the fixed part 4'
The force applied to the taper must be supported by the core rod 7. Therefore, in this case, an incompressible and strong core rod is used. These sheaths and cores are expensive or occupy a large volume, reducing the filling factor of the hollow fibers. In the apparatus shown in FIG. 3, the cartridge is fixed to the container only by the sealing material 5, so when a fluid pressure loss that exceeds the frictional resistance between the sealing material and the container occurs,
In order to prevent the cartridge from being pushed to one side, a strong, non-compressible material must be selected for the sheath 3. The compressive force exerted on the sheath due to the pressure loss of the fluid, for example in the device shown in Figure 3, is
10cm, pressure loss is 2Kg/ cm2 , approximately 150Kg
reach even. Therefore, like the device of FIGS. 1 and 2, the material of the sheath of this device is either expensive or occupies a large volume, reducing the filling factor of the hollow fibers.

価である装置となつている。 FIG. 4 is a schematic cross-sectional view of an example of the device of the present invention. Compared to conventional devices, the seal between the container and the cartridge is performed by sealing materials 5 and 6, but all the force applied to these is transmitted only from the fixed part 4, and that force is not transmitted to the sheath. No, the cartridge is secured to the container with a clasp. Due to these structures, almost no stress is placed on the sheath 3 during sealing or during operation.
Therefore, the only strength required of the sheath is that it does not shrink excessively due to the frictional resistance of the sealing material 5 when the cartridge is inserted. As a result, it has features such as a high filling rate of hollow fibers in the container.
As a result, although it is a cartridge type device, it is easy to handle and replace, can withstand long-term high-pressure operation, has a large effective membrane area per volume, and is inexpensive to replace.

剤に容易に求められる。 As mentioned above, in this device, the cartridge is fixed to the container by the fastener, so the force necessary for fixing the cartridge and the pressure loss of the fluid are absorbed by the fixed part 4.
The force required for sealing is supported by the fixed part 4.
Therefore, the adhesive must be strong and hard. Such properties are easily required for many thermosetting adhesives such as general-purpose epoxy resin adhesives, polyester adhesives, and polyurethane adhesives.
本発明に使用することができる鞘は、前記した

い、望ましくは0.5％以上は、更に望ましくは0.2

は縮まないものであるのがよい。 The compressive force applied to the sheath when inserting the cartridge is due to the frictional resistance of the sealing material 5, as described above. A rubber ring is usually used as the sealing material 5. For example, when an O-ring is used, the frictional resistance between the inner wall of the container 1 and the O-ring is equal to the unit length of the O-ring in the circumferential direction when water is used as a lubricant. Satori
It will be about 400g/cm. In addition to the O-ring, rubber rings of various shapes can be used, and the frictional resistance in that case is about the same as that of the O-ring, although it differs slightly depending on the finishing precision of the inner wall of the container and the lubricant. Therefore, the sheath used in the present invention preferably does not shrink by more than 0.5%, more preferably by more than 0.2%, when a compressive stress of 400 g/cm is applied per unit length in the circumferential direction of the sheath. good.

具体例としてあげられる。 Specific examples include a thin plastic pipe with many holes, a tubular net, and a tubular gridiron.
中空糸束は、このような鞘の中に40％以上、場
合によつては50％以上充填する事が可能である。
但し、充填率は次式で定義される。 It is possible to fill such a sheath with a hollow fiber bundle of 40% or more, and in some cases 50% or more.
However, the filling rate is defined by the following formula.
充填率＝中空糸の断面積×鞘内の中空糸の数／サヤの
断面積

鞘が完全な円形断面でなく、多少凹凸のある場合
はその外接円、円接円の直径をDo、Diとしこれ
を相当外径Do、相当内径Diとする。 Filling rate = cross-sectional area of hollow fiber × number of hollow fibers in sheath / cross-sectional area of sheath × 100 (%) ...Here, the cross-sectional area of hollow fiber is πd 2 0 /4, assuming that the outer diameter is do and the inner diameter is di. The cross-sectional area of the sheath is given by πD 2 0 /4 using the equivalent outer diameter Do of the sheath. however,
If the sheath does not have a perfectly circular cross section and has some unevenness, the diameters of its circumscribed circle and circumscribed circle are Do and Di, and these are the equivalent outer diameter Do and the equivalent inner diameter Di.
中空糸の数をｎとすると式は
充填率＝（d0／D0）2・ｎ×100（％）

を用いると本装置では充填率が60％以上、場合に
よつては80％以上に達せしめうる。このような高
充填率のカートリツジタイプの装置はまだ得られ
ていない。When the number of hollow fibers is n, the formula is: Filling rate=(d 0 /D 0 ) 2 ·n×100 (%). By using the equivalent inner diameter of the sheath instead of the equivalent outer diameter, the device can achieve a filling rate of over 60%, and in some cases over 80%. A cartridge type device with such a high filling rate has not yet been obtained.
相当内径を用いて表わした充填率を高くする例
えば70％以上にするためには、鞘内の糸がなるべ
くたるんでいないようにする必要がある。但し、
たるみ量は次式で与えられる。 In order to increase the filling rate expressed using the equivalent inner diameter, for example 70% or more, it is necessary to prevent the threads within the sheath from sagging as much as possible. however,
The amount of slack is given by the following formula.
たるみ量＝Ｌ−L′／Ｌ×100（％）
（Ｌは糸を張つた状態の長さ、L′はたるんだ状態
の両端間直線距離）
すなわち鞘内の中空糸のたるみ量は、糸の90％
以上、好ましくは97％以上更に好ましくは99％以
上がたるみ量0.5％以下である事が好ましい。た
だ糸の全数がたるみ量0.5％以下であるのが最も
好ましいのは言うまでもない。 Amount of slack = L - L' / L x 100 (%) (L is the length of the thread in a stretched state, L' is the straight line distance between both ends of the thread in a slack state) In other words, the amount of slack in the hollow fiber inside the sheath is 90% of
Above, preferably 97% or more, more preferably 99% or more, the amount of slack is 0.5% or less. However, it goes without saying that it is most preferable for the total number of yarns to have a slack amount of 0.5% or less.

%, the hollow fibers may bend within the sheath, and when a coarse sheath is used, the hollow fibers may be sucked in and broken near the fluid outlet 12 of the second fluid.

である。Example 1100 polysulfone (manufactured by Union Carbide Co., P = 1700) hollow fibers made by a wet method, outer diameter 1.17 mm, inner diameter 0.76 mm, length 1.2 m, were bundled under running water.
Wrapped in a polyethylene sleeve (HR-1, manufactured by Dainippon Plastics Co., Ltd.) and soaked in hot water at 97℃ for 1 hour.
Soaked for an hour. While taking out the dense bundle from the sleeve, a 1 m long tubular net (Dainippon Plastics Co., Ltd.
It was inserted into Nettring N-2) manufactured by Co., Ltd. The hollow fiber bundle was left in a semi-dry state by leaving it as it was for a day and night.
The bundle of hollow fibers was trimmed so that the hollow fibers were 6 cm long from both ends of the sheath, and the tips were clamped in a vise from about 2 cm apart to crush the hollow fibers until no air could pass through them. Next, both ends were fixed using a mold shown in FIG. Epoxy resin adhesive (Ciel Chemical: Epicoat 828, curing agent: tetraethylene pentamine) as a fixing agent
was used to inject from injection port 20 at a rate of 10 g per minute for 16 minutes. The adhesive did not enter into the hollow fibers, but filled only between the hollow fibers. After curing, apply after cure.
After heating at 130°C for 1 hour, the mold was broken and the hollow fiber bundle was taken out. The other end was also fixed in the same way. The fixed portion was cut at the line AA in FIG. 5 to open the hollow fiber. The characteristics of this cartridge are as follows.
