TUBE TYPE-MOLDED OBJECT CAPABLE OF WRAPPING MEMBRANE MODULES OVERALL AND REINFORCED CASE FOR INDUSTRIAL FILTER}

The present invention relates to a tube molded body that can wrap the entire membrane module, and an industrial filter reinforcement case using the same. More specifically, the lapping process using a conventional lapping bath liquid by simple operation by physically fastening a transparent plastic tube molded body By replacing them, the membrane module is protected by assembly without any additional equipment required for the lapping process, thereby reducing the time and cost of the lapping process, minimizing the stagnation of feed water when the product is mounted, and by the holes formed in the tube formed body. The present invention relates to a tube molded body that can solve the problem of water stagnation and improve differential pressure, and an industrial filter reinforcement case using the same.

The membrane manufacturing process is largely carried out by five processes. The first primary coating process is to coat the polymer solution on the nonwoven fabric, thereby improving physical properties of the reverse osmosis membrane, and from this process, solvent-non-solvent phase separation process. Through the pore structure of the support layer can be formed.

The second process is a secondary coating process of forming a polyamide (POLYAMIDE) coating layer by the interfacial polymerization of amine and acid on the first coated support layer. The resulting salt removal function is realized by the polyamide (POLYAMIDE) coating layer formed.

In the third process, membranes, tricots and meshes are rolled into spiral wound modules, which are then wrapped again. At this time, the lapping process is a required process because it can protect the membrane from impact when handling the module and prevent telescoping during high pressure operation. In addition, the lapping process may prevent the module from being damaged due to the differential pressure.

Thereafter, the fourth step is a step of determining whether or not the physical properties of the processing module have passed. The purified water (Flux) for measuring the amount of filtration in a unit time, the rejection (Rejection) for measuring the ability to remove impurities in raw water, and the total in raw water It determines with TOC removal rate which measures the removal ability of organic carbon (TOC).

Finally, the fifth process is a post-treatment process that performs sterilization conditions-chemical treatment to prevent the growth of microorganisms and viruses that may occur during distribution. The superior products that go through all the above processes are shipped after the final inspection and packaging.

Thus, the present invention will be described with respect to the lapping process after rolling in the membrane manufacturing process. FIG. 1 shows a membrane module in which a polyamide layer is formed on a support layer in a membrane manufacturing process, and rolls a membrane, tricot and mesh into spiral wound modules in an outward direction from a central axis. After machining, the end cap is attached to both ends of the membrane module after trimming, and the wrapping process is shown step by step for the membrane module fixed by the end cap.

At this time, the wrapping (Wrapping) process is carried out under high pressure conditions, so that the product to withstand high pressure reinforces the module appearance with fiber reinforced plastic (FRP) using glass fiber and epoxy resin.

FIG. 2 illustrates the lapping process in detail in the membrane manufacturing process. First, a lapping crude liquid in which an epoxy resin and a curing agent are mixed at an appropriate blending ratio is prepared, and glass fibers are impregnated into the lapping crude liquid containing an epoxy resin. Then, the glass fiber coated with the epoxy resin in the above is carried out in a manner that wraps the outside of the rotating membrane module. At this time, the residual epoxy resin can evenly spread the cross-section using a silicone pad, transfer the wrapped module as described above to the curing room, and then harden.

However, once wrapped product is difficult to change the label, it requires equipment for wrapping, and a separate curing room for curing. In addition, the lapping equipment is difficult to clean, and the appearance must be trimmed before evaluation, and the end cap must be separately installed.

In such a conventional lapping process, as a crude liquid made of an epoxy resin is used, it is difficult to handle because a long curing time of about 6 to 12 hours is required due to the wettability of the epoxy resin itself. In addition, the mixing ratio between the epoxy resin and the curing agent used in the lapping bath solution affects the degree of cure and curing time, which makes it difficult to control the mixing ratio, and also generates waste fluid due to poor lapping bath mixing. It takes For example, there is an additional cost due to the preparation and disposal of a separate waste solution, and it is difficult to handle because it generates heat during curing.

In addition, since the epoxy resin once cured is difficult to remove and must be performed by hand, the cost is increased and a difference in the amount of crude liquid removal is generated between workers. On the other hand, when the residual amount of epoxy is small, glass fiber swelling occurs. In addition, when wrapped with glass fibers coated with a conventional epoxy resin, water is stagnant in the membrane and contamination is inevitable.

In an effort to solve this problem, an attempt has been made to replace a wrapping material called a polypropylene net in a full-fit method, but in this case, stagnant water in the membrane can be avoided, but another problem with low recovery rate Is being pointed out.

Accordingly, the present inventors have tried to solve the problem in the lapping process after rolling in the manufacturing process of the conventional membrane, as a result, the rolled membrane module to replace the process of lapping with glass fiber coated with a conventional epoxy resin to a plastic molded body The present invention has been completed by casing by physical fastening and forming holes in the plastic molded body to solve the problem of water stagnation.

In addition, by not using the lapping process using the conventional lapping bath solution shown in Figure 2, it is possible to solve the problems such as time, procedure, etc. due to the curing of the lapping bath solution, and by separate reuse after use, additional processing costs are not required Therefore, the manufacturing cost of the membrane can be lowered.

In addition, the tube molded body of the present invention is a tube molded body made of a transparent plastic material having the same outer diameter manufactured through a mold, and has excellent outer diameter dimensional stability. Due to these characteristics, the tube molded body of the present invention can prevent the occurrence of the difference in the outer diameter according to the operator, the unevenness of the raw material mixture in the process of winding using epoxy resin and glass fiber in the case of the lapping process using the conventional lapping bath liquid.

Thus, the outer diameter of the tube molded body of the present invention should be able to include the entire wound membrane module, it is preferable that the outer diameter is enough to be spaced apart at intervals of 2 mm or less between the membrane module and the tube molded body. In this case, the separation distance is sufficient to compensate for the degree of swelling of the membrane module during water flow, and in actual application, the membrane module swells to fill the space.

When manufactured by the conventional membrane manufacturing method, the flow path is not formed except the ATD surface and the pipe inner diameter side in which the water comes out, but the tube molded body of the present invention makes a new flow path by making a hole in the product appearance as needed. It can be formed, and from the formation of the flow path by the hole, it is possible to improve the fouling resistance of the membrane and to improve the differential pressure to prevent module breakage.

In addition, the tube molded body of the present invention, which can wrap the entire membrane module, does not require a separate work space or facility for lapping because the lapping process is replaced with a case type.

A first preferred embodiment for implementing a tube molded body which can wrap the whole membrane module of the present invention is a semi-cylindrical tube molded body in which the end caps shown in FIGS. 3 to 6 are integrated.

More specifically, end cap-integral semi-cylindrical members 10 and 20 are designed to support the entire membrane module and have an outer diameter that can be spaced apart from the supported membrane module at intervals of 1 to 2 mm. At this time, the end cap integrated semi-cylindrical members (10, 20) are fastened at regular intervals around the molded body of the end cap integrated semi-cylindrical members (10, 20) to be fastened by the upper and lower hooks (11) and grooves (12).

Thus, by selectively selecting the raw materials according to the acid resistance, alkali resistance, pressure resistance, etc. to produce a product required by the customer.

Preferably, while satisfying the above requirements, a heat-resistant transparent resin or elastic transparent resin is used. Specifically, specifically, polypropylene resin, acrylonitrile butadiene styrene copolymer resin (acrylonitrile-butadiene-styrene copolymer), acrylic resin, polymethyl methacrylate (PMMA) resin, polycarbonate (PC) resin, cyclo-olefin co It is to use any one transparent plastic material selected from a polymer (Cyclo-Olefin Copolymer, COC) resin and a cyclo-Olefin Polymer (COP) resin.

In the case of a membrane that has been subjected to a lapping process using a conventional lapping bath liquid, the appearance of the product becomes a mortar when the product is mounted, whereas the tube molded body of the present invention has the same outer diameter made through a mold, so that the appearance can be manufactured in a straight type. Therefore, stagnation of feed water can be minimized when the product is mounted.

At this time, the industrial filter reinforcement case of the present invention is spaced apart by 2mm or less space between the membrane module and the tube molded body, and furthermore, the distance between the tube molded body and the facility vessel is spaced 2mm or less, and the air is once filled Do not let the water run out again. In the case of using the end cap integrated plastic case of the present invention, the separation distance between the product and the mounting vessel is minimized. Therefore, the present invention does not need to separately install the U-CUP to be mounted because the appearance of the conventional product shrinks in the shape of a mortar and inevitable water stagnant space.

In addition, the industrial filter reinforcement case of the present invention can support two or more membrane modules in series in the tube molded body without being spaced apart to ensure the maximum effective membrane in the same product specifications. That is, since the end cap is not required for each module unit, the effective film of the actual product can be increased.

In addition, the industrial filter reinforcement case of the present invention can form a new flow path by forming a hole (hole) in the tube molded body. In the present invention, the hole is formed in the tube molded body to guide the flow path, thereby increasing the fouling resistance of the membrane and improving the differential pressure, thereby ultimately preventing breakage of the membrane module. At this time, it is preferable to form a hole in the back of the tube molded body, or if the flow path is formed due to the hole can be improved the differential pressure forming position will not be limited. In addition, the size and number of the holes are not particularly limited, and may be changed by those skilled in the art for design.

9 is a photograph comparing the appearance (top) of the product obtained by the lapping process of the present invention and the appearance (bottom) of the product obtained by the conventional lapping process, the product produced by the conventional method is a module after re-evaluation when a performance problem occurs However, since the product of the present invention using a transparent plastic tube molded product can be seen from the outside, the state of the product can be easily confirmed, and it can be checked and coped without disassembling according to the performance problem.

In addition, since it is a plastic case type, it is easy to be separated by detachment of a tube molded body when discarding after using the product, and it is environmentally friendly at the time of disposal because it can be reused by distinguishing it according to raw materials.

Furthermore, the industrial filter reinforcement case of the present invention can be reduced in the production time and the production cost can be reduced because the lapping process is changed to the case type does not require a separate work space or equipment for lapping.

Hereinafter, the present invention will be described in more detail with reference to Examples.

A 140 μm thick porous polysulfone scaffold with a nonwoven fabric on the back was immersed in an aqueous solution containing 2 wt% meta-phenylenediamine (MPD) and 0.2 wt% 2-ethyl-1,3-hexanediol for 40 seconds. After removal, excess aqueous solution on the support was removed. Then, the coated support is ISOPAR

A polyamide reverse osmosis composite membrane was prepared by immersing for 1 minute in a solution containing 0.1% by weight of trimezoyl chloride (TMC) in a solvent (Exxon Corp.) to remove excess organic solution from the support.

Thereafter, the polyamide reverse osmosis composite membrane, a tricoat, and a mesh were rolled on the central axis outward from the central axis to prepare a spiral wound membrane module.

The spiral wound membrane module was immersed in a semi-cylindrical end cap integral tube made of polypropylene resin, and then covered with the other semi-cylindrical tube, and joined by a pre-fabricated hook type (11, 12) fastening structure.

After carrying the spiral wound membrane module at the open inlet of the one 50 cm long cylindrical member 40, another 50 cm long cylindrical member 40 was inserted and fastened (FIG. 8). The fastening between the molded bodies was made to be fastened by a pair of screw fastening portions 42 on the open inlet side. At this time, fabrication of the spiral wound membrane module was performed in the same manner as in Example 1.

&Lt; Comparative Example 1 &
