は容易でない。 A spiral type liquid separation element basically consists of a central tube, a semipermeable membrane surrounding it, a separated liquid channel material, and a stock solution channel material, and has an extremely complex structure. And the manufacturing method is a known example OSWRe
- As seen in port No. 879, No. 341, U.S. Patent No. 3386583, U.S. Patent No. 339790, etc., each has an extremely complicated device structure with a tension mechanism for each material. There is. Furthermore, even if these complicated devices having tension mechanisms are used, it is not easy to roll up each material tightly without causing wrinkles.

に巻き上げることが困難となる。 In other words, when tightly wrapping a sheet-like material around a central tube, it is necessary to apply sufficient tension to the material, but as in the manufacture of spiral-type separation elements, it is necessary to apply adhesive to the necessary places and apply sufficient tension to the material. When wrapping multiple materials with different shapes around a central tube at the same time, the apparent width may vary due to uneven thickness of each material, uneven overlap between different materials, thickness of adhesive applied to the materials, etc. The situation is the same as wrapping a material with large thickness unevenness in the direction. If a material with large uneven thickness is rolled one after another, the winding will become uneven as the winding progresses, and eventually wrinkles will appear in the material. Wrinkling is exacerbated as the tension applied to the material increases, making it difficult to roll it up as tightly as required.
スパイラル型分離素子において素材のシワ、こ
とに半透膜のシワは膜に欠陥を与え、分離素子の
性能をそこなう。 In a spiral type separation element, wrinkles in the material, especially wrinkles in the semipermeable membrane, cause defects in the membrane and impair the performance of the separation element.

いものであつた。 Another known example is the technique disclosed in Japanese Unexamined Patent Publication No. 50-2681, which the present inventors have already proposed, but in this technique, the semipermeable membrane is cut at each end, and each end is individually glued. Seals are sealed with adhesives, which require high material costs, require a bonding process that is time-consuming, and are prone to leakage.Furthermore, with such adhesive-sealed products, the semipermeable membrane in the seal area may not function properly. Therefore, the effective membrane area was low, resulting in poor efficiency.

An object of the present invention is to provide a method for manufacturing a spiral-type liquid separation element that can be wound as tightly as possible.

巻き上げがタイトになり、目的のスパイラル型分
離素子を形成することが出来る。 That is, in the present invention, each material of the first semipermeable membrane/undiluted solution channel material/second semipermeable membrane/separated solution channel material is made into one set, and these are stacked in advance as a single set or multiple sets. Next, one end of at least one piece of the separation liquid channel material is brought into contact with and fixed to the central tube, and then the above-mentioned material group is wrapped around the central tube. At this time, tension is not actively applied to each material, and even when tension is applied, the number of materials is limited and the tension is applied to an extent that does not cause wrinkles in the material due to the above-mentioned phenomenon. Therefore, at this stage, the finished state is relatively loosely wound, but since the material is wound with no tension or with relatively low tension, no wrinkles occur in the material. Next, while applying an external force to the cylindrical outer periphery of the thus rolled up separation element shape, it is rotated about the central tube as an axis. As the rotation continues, each material is sequentially shifted based on the separation liquid channel material fixed to the central tube, and the winding becomes tighter, making it possible to form the desired spiral type separation element.
分離素子の巻き上げ状態がタイトであることは
分離素子使用時の形くずれの問題、さらに逆浸透
法においては濃度分極の問題などの点で重要であ
る。 Tight winding of the separation element is important in terms of problems such as deformation of the separation element during use and concentration polarization in the reverse osmosis method.

ローラが望ましい。外力を与える点は一点である
と中心管がたわむ怖れがある。従つて２点、望ま
しくは力バランスの点で３点又はそれ以上である
ことが望ましい。 As a means of applying external force to the outside diameter of the cylinder, it is desirable to apply an external force to the entire length of the separation element, that is, the entire width of the spread material.Although it is possible to apply a force to the outside diameter of the cylinder with a fixed bar, etc., It is preferable to use a roller because it does not damage the outer periphery of the separation element. Furthermore, it is preferable to compact the material sequentially starting from the center tube side; a fixed bar or the like may cause the material to be compacted from the outside, so from this point of view as well, a rotating roller is preferable. If only one point is applied external force, there is a risk that the central tube will bend. Therefore, it is desirable to have 2 points, preferably 3 points or more in terms of force balance.

果的である。 As mentioned above, the phenomenon in which the materials are compressed must be performed sequentially starting from the center, but if the displacement between the materials when collapsing is only in the lateral direction, it may cause wrinkles in the materials in some cases. become. In this case, the generation of wrinkles can be prevented by separating the overlapping materials and shifting them. As specific means, in addition to using a relatively stiff material, it is effective to apply the above-mentioned external force locally and apply a strong force.

も考えられる。 In the case of the present invention, the stacking of materials, which is also a preparatory step, is advantageous in that it can be performed in one plane compared to known examples, and the application of adhesive is also easier. It is also effective as a means to prevent drying in the case of semipermeable membranes that require a moist state. Furthermore, it is extremely advantageous when manufacturing a separation element using a continuous semipermeable membrane, which will be described later. In order to make the rolled-up shape of the separation element symmetrical, it is necessary to stack each material group in a shifted state in advance. All of the material groups may be stacked together, but if a large separation element is to be manufactured, a certain number of them may be stacked one on top of the other and placed on the left and right sides of the center tube, or they may be placed on a shelf or the like in a three-dimensional manner. It is also conceivable to wrap it around the central tube in a state where it is placed in the center.

要以上に用いることになり、コスト面からも不利
であり、又、膜充填密度、すなわち分離素子性能
の面からも不利である。 According to the method of the present invention, it is possible to easily manufacture a separation element using a plurality of consecutive sets of first semipermeable membranes and second semipermeable membranes. US Pat. No. 3,386,583 is a known method for manufacturing a spiral separation element using a continuous semipermeable membrane. When put into practical use, this method requires complicated equipment, but it also has the disadvantage of requiring the use of continuous separation liquid flow path materials and concentrate flow path materials according to the present invention. As a result, the material composition according to the present invention is as follows: first semipermeable membrane/diluted solution channel material/diluted solution channel material/second semipermeable membrane/separated liquid channel material/separated liquid channel material. This results in the use of more stock solution channel material and separated liquid channel material than necessary, which is disadvantageous in terms of cost and also disadvantageous in terms of membrane packing density, that is, separation element performance.

いられる利点は多い。 With the manufacturing method of the present invention, it is of course possible to manufacture a separation element using a large number of concentrate channel materials and separated liquid channel materials; A separation element using a continuous semipermeable membrane is the most excellent, and such a separation element can also be manufactured very easily by the method of the present invention. Note that the present invention is more effective in making the semipermeable membrane continuous in a separation element made up of multiple groups of materials than in a separation element made up of a single group of materials. Regarding the degree of continuous semipermeable membrane, it is most preferable to have one semipermeable membrane continuous for one separation element, but if the separation element becomes large, the number of continuous semipermeable membranes is It is also possible to divide it into pieces. There are many advantages to using a continuous semipermeable membrane in a separation element constructed from multiple sets of materials.

が増すにつれその不利益の程度は大きくなる。 In a completed structure, a separation element composed of multiple sets of material groups has first semipermeable membranes and second semipermeable membranes alternately connected in the longitudinal direction. Glue is generally used to connect. Semipermeable membranes, on the other hand, are generally manufactured as long continuous membranes. Therefore, it is obvious that it is disadvantageous to cut this continuous film into short pieces for the purpose of manufacturing separation elements, and then connect them with adhesive to make them continuous during the process of manufacturing separation elements. Furthermore, there are many disadvantages such as the cost of using the adhesive, leakage from the bonded portion, and a reduction in the effective membrane area of the bonded portion, and the degree of these disadvantages increases as the number of material groups increases.

ある。 Therefore, as long as the method of the present invention is used, the separation element composed of a plurality of material groups obtained by the present invention and using a continuous semipermeable membrane can reduce the material cost and reduce the bonding process. It is a separation element that is inexpensive and has excellent performance in terms of reduced leakage points and increased effective membrane area.
