端末シール方法に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a tubular membrane separation module, and more particularly, to a method for sealing an end of a tubular membrane separation module.

トを高める要因となっている。2. Description of the Related Art In conventional tubular membrane separation modules, the permeable membrane is supported by a porous FRP tube or a perforated stainless steel tube. However, when these tubular membrane separation modules are used under a relatively low pressure such as ultrafiltration or microfiltration, the permeable membrane does not need pressure resistance enough to be supported by the porous FRP tube, The conventional module is rather excessive quality, which increases the processing cost.

を招いている。Further, in the conventional tubular membrane separation module, the permeable membrane and the porous support tube are sealed at their tube ends by using a packing, a retainer or other sealing member, but as long as it has such a structure, However, it is difficult to tightly bundle the tubular permeable membranes together, and the membrane area per unit volume of the module must be small. In addition, since the flow path cross-sectional area of the module is reduced in the seal portion, pressure loss is likely to occur, leading to a decrease in module performance, particularly water permeability.

大する。On the other hand, a hollow fiber type or spiral type membrane separation module has been developed in order to increase the performance of the membrane separation module, particularly the membrane area per unit volume of the module. However, these modules are apt to be clogged, and it is difficult to physically clean such as ball cleaning for preventing scale adhesion. Therefore, in order to use such a module, it is necessary to pretreat the undiluted solution, and the treatment cost increases as the number of treatment steps increases.

The method for sealing the end of the tubular membrane separation module in the application is not described in detail, so that the casting resin material does not infiltrate into the nonwoven fabric tube before casting.
In addition, at least one step is necessary to prevent the non-woven fabric tubes from contacting each other. In general, before casting, insert a mold with protruding pins for the number of non-woven pipes at the end of the non-woven pipe, fill it with a casting resin material, cast it, and solidify it. The method of removing the mold is used. Another commonly used end-sealing method is to cast a casting resin material to a height of several cm from the opening end, and inject the resin material into the pipe to solidify it. Stop the section once. Next, there is a two-time filling method in which the resin material is filled to a required filling height, cast, and solidified, and then the first cast height, that is, the filled height is cut. .

Further, since the non-woven fabric tubes are often in contact with each other, the flow path resistance of the permeated liquid is increased, and as a result, the permeation flux is reduced, so that a membrane separation module with a low yield is manufactured for quality assurance. Further, in the method disclosed above, since the mold attaching / detaching process requires the same manufacturing time, and in order to prevent the non-woven fabric tubes from contacting each other, the non-woven fabric tube should not be twisted or distorted. The mold has to be fitted carefully, resulting in much more time.

It is preferable that they are arranged so as not to be in contact with each other by coating with, and the casting resin material 5 is filled between them. The length of the nonwoven fabric tube 2 may be substantially equal to the length of the outer cylinder 1.

It is desirable that it is m to 25 mm. When the hardness of the sheet material 4 exceeds 60 °, when the water-permeable nonwoven fabric tube 2 is pressed, the water-permeable nonwoven fabric tube 2 may not be sufficiently adhered to the sheet material 4 due to the variation in the length and the inclination of the end surface. This is because the casting resin material 5 may infiltrate into the water-permeable nonwoven fabric tube 2. Further, when the thickness of the sheet material 4 is less than 3 mm, even if the hardness is small, it is not possible to absorb the variation in the length of the water permeable nonwoven fabric tube 2 and the inclination of the end face, and the casting resin material 5 is permeable to water. This is because the non-woven fabric tube 2 may enter the inside.
When the thickness of the sheet material 4 is 25 mm or more, when the nonwoven fabric tube 2 is pressed against the sheet material, the nonwoven fabric tube 2 is distorted and deformed due to the large repulsive force due to the elasticity of the sheet material, and the amount of permeated water is reduced. Because there is something to do.

い。Cylindrical woven fabric 3 covering the non-woven pipe 2
Has a large water permeability, its inner diameter is somewhat larger than the outer diameter of the nonwoven fabric tube 2, and is made of polyester, polyethylene, nylon, polypropylene, polyamide or cellulose, and the thickness of each is 0.5 mm to 3 mm. desirable. By covering the non-woven tube 2 with a cylindrical woven cloth 3, the non-woven tube 2 and the non-woven tube 2
The outer cylinder 1 and the outer cylinder 1 are arranged so as not to contact each other at both ends thereof. The thickness of the cylindrical woven fabric 3 is 0.5 mm.
If it is less than the above range, the interval between the non-woven fabric tubes becomes small, so that the elasticity of the sheet material pressed by the non-woven fabric pipe 2 cannot absorb the difference in the length of the non-woven fabric pipe, which may deteriorate the sealing property. If the thickness of the cylindrical woven fabric 3 exceeds 3 mm, the flow resistance of the cylindrical woven fabric 3 increases, the water permeability deteriorates, and the amount of permeated water decreases, which is not preferable.

If the cylindrical woven fabric 3 is shorter than the nonwoven fabric tube 2 but the difference is less than 5 mm, the fluidity of the resin will be impeded by the cylindrical woven fabric 3 when it is filled with the casting resin material, and it will deteriorate. Is. If the difference exceeds 25 mm, the amount of resin must be increased by the thickness of the cylindrical woven cloth 3.
This is because it leads to an increase in manufacturing cost.

By pressing the non-woven fabric pipe against a specific sheet material, it is possible to easily prevent the non-woven fabric pipe from entering when the casting resin material is injected, so it is easier and cheaper than the conventional terminal sealing method. Can be manufactured. Further, by covering the non-woven fabric tube with a cylindrical woven fabric, an appropriate non-woven fabric pipe interval can be provided, so that the flow passage cross-sectional area of the permeated water does not become small at the seal portion, and the pressure loss is extremely small. Therefore, the undiluted solution can be supplied at a high flow rate, scale adhesion is suppressed, and the permeation flux is less likely to decrease.
