本考案は透過性膜の浸透作用により原水を濃縮

ル型膜分離モジールにおける原水流路材に関す
る。[Detailed Description of the Invention] The present invention relates to a liquid separation device that concentrates or separates raw water by the osmotic action of a permeable membrane, and relates to a raw water channel material in a spiral type membrane separation module.

られ、凹凸を有する波形シートなども提案されて
いる。 The raw water channel material is superimposed on a three-layer structure in which both sides of the permeated water channel material are wrapped with semi-permeable membranes and three sides of the membrane envelope are sealed, with one open side of the membrane envelope communicating with the permeated water collection pipe. A so-called spiral type membrane separation module (hereinafter referred to as a spiral module) is known, in which this membrane is wound around a permeated water collection pipe as an axis. Such spiral modules include those in which multiple membrane envelopes are rolled up, those in which the raw solution flows parallel to the water collection pipe, or those in which the wound membrane envelope is directed toward the water collection pipe axis or from the axis to the periphery. Many variations are known, such as a method in which the liquid flows in a spiral direction.
A porous material having a lattice structure is generally used as the raw water channel material for such a spiral module, and corrugated sheets having unevenness have also been proposed.
この格子構造を有する多孔性材料として、従来
平行な多数のプラスチツクフイラメントを互に斜

に損傷を与える欠点があつた。また、網状材料は
巻き付けの際の引張力により容易に変形するの
で、部分的なたるみが生じるなどして巻付け作業
が難しい欠点があつた。 Conventionally, porous materials with this lattice structure were made by stacking a large number of parallel plastic filaments diagonally across each other to form two layers, and then fusing each intersection point to form a net. . Such a net-like structure has the drawback that the intersection points are particularly thick and protrude, so that when wound around the spiral module, the membrane surface is strongly pressed, causing damage to the membrane. In addition, since the net-like material is easily deformed by the tensile force during winding, it has the disadvantage that it is difficult to wind the winding work due to partial sagging.
また、従来シート状流路材として、両面に互に
斜交する連続した突起を有する構造のものが提案
されているが、流路断面積当りの空隙率が低く動
水抵抗を増すので、ネツト状のものに比べて厚い
材料を使う必要が生じ、そのためモジユールの容
積当りの膜面積を低下させる欠点があつた。 In addition, conventional sheet-like channel materials have been proposed that have continuous protrusions diagonally intersecting each other on both sides, but the porosity per cross-sectional area of the channel is low and increases hydraulic resistance, so It became necessary to use a thicker material than in the case of a cylindrical type, which had the disadvantage of reducing the membrane area per unit volume of the module.

つた。 As another form of sheet-like channel material, it has also been proposed to use a corrugated sheet. However, when the thickness of the sheet is very thin like the spiral module in this invention, the waveform stretches when it is wound, making it difficult to maintain the necessary gap. The disadvantage was that the stirring and mixing effect of the method was weak and the concentration polarization effect was increased.

できる。 When using the product of the present invention, the tops of the protrusions 1 and 2 are in contact with the membranes, and the space between the membranes is guided by the flat part and protrusion of the raw water channel material of the product of the present invention. raw water flows. Therefore, since the protrusions 1 and 2 always make surface contact with the membrane over a predetermined area or more, the membrane surface is not damaged during the winding operation or during long-term use. Further, while the raw water flows along the longitudinal direction of the protrusion, a portion of the raw water is diverted through the grooves of the recesses 5 and 6 to perform an appropriate stirring and mixing action. As a result, the pressure loss coefficient, which indicates hydraulic resistance, was reduced compared to the conventional net-like structure. In addition, the length is 1 to 5 mm, and the height
Since the 0.2 to 0.7 mm protrusions are densely and regularly arranged, it is strong and will not deform during the winding process. Furthermore, since the product of the present invention is manufactured by hot embossing of plastic film, it does not require expensive molds unlike conventional net processing, and can be manufactured easily and inexpensively.
