Description
【０００１】[0001]
本考案は飲料水の濾過に用いる膜モジュ−ルの改良に関するものである。 The present invention relates to an improvement of a membrane module used for filtering drinking water.
【０００２】[0002]
飲料水を膜モジュ−ル、例えば中空糸膜モジュ−ルによって濾過する場合、原 水を粒状活性炭層に通して原水中の塩素系消毒剤を吸着除去してから膜で濾過し ている。従って、粒状活性炭層と膜との間の水には消毒剤が含まれておらず、雑 菌が繁殖し、この繁殖した雑菌が膜面で阻止され堆積されて死滅・腐敗し、その 悪臭が膜を通して透過側に放出されるので、この防止が必要である。 When drinking water is filtered with a membrane module, for example, a hollow fiber membrane module, raw water is passed through a granular activated carbon layer to adsorb and remove the chlorine-based disinfectant in the raw water, and then filtered with a membrane. Therefore, the water between the granular activated carbon layer and the membrane does not contain a disinfectant, and germs propagate, and these germs are blocked and accumulated on the membrane surface, killing and spoiling, and the odors This prevention is necessary as it is emitted through the membrane to the permeate side.
【０００３】 また、使用前にエア−リ−クテスト（膜モジュ−ルの出口を封じ、入口側から エアを圧入し、膜モジュ−ルを水中に浸漬した状態でエアリ−クを試験する）を 行なうことも必要である。In addition, before use, an air leak test (sealing the outlet of the membrane module, pressurizing air from the inlet side, and testing the air leak with the membrane module immersed in water) It is also necessary to do.
【０００４】 図４の（イ）は、上記の条件を充足するために提案された中空糸膜モジュ−ル を示し、下部ケ−ス片１０’内の上下の網７１’，７２’で仕切った空間に粒状 活性炭を入れ、この下部ケ−ス片１０’内の上側に水溶性物質膜５１’を張設し 、該膜５１’上に抗菌性粉末５’を入れ、かかる粒状活性炭入りの下部ケ−ス片 １０’を、中空糸膜束を収容した上部ケ−ス片１’に結合してある。FIG. 4A shows a hollow fiber membrane module proposed for satisfying the above conditions, which is divided by upper and lower nets 71 'and 72' in a lower case piece 10 '. Granular activated carbon is put in the space, a water-soluble substance film 51 'is stretched on the upper side of the lower case piece 10', and antibacterial powder 5'is put on the film 51 '. The lower case piece 10 'is joined to the upper case piece 1'which contains the hollow fiber membrane bundle.
【０００５】 この中空糸膜モジュ−ルにおける水溶性物質膜５１’は、膜モジュ−ルを給水 栓に取り付けるまでの間、抗菌性粉末５’が網７１’，７２’並びに粒状活性炭 ７’の隙間を経て原水入口６’より逸出するのを防止するために必要であり、通 水を開始すれば、水溶性物質膜の５１’の溶解によって抗菌性粉末５’が中空糸 膜表面に付着される。The water-soluble substance film 51 ′ in this hollow fiber membrane module has the antibacterial powder 5 ′ of the nets 71 ′, 72 ′ and the granular activated carbon 7 ′ until the membrane module is attached to the faucet. It is necessary to prevent the water from escaping from the raw water inlet 6'through the gap. When water is started, the antibacterial powder 5'is attached to the hollow fiber membrane surface due to the dissolution of the water soluble substance membrane 51 '. To be done.
【０００６】 従って、粒状活性炭７’による消毒剤の除去のために雑菌の繁殖し易い状態に ある上部ケ−ス片１’内でのその雑菌の繁殖を、長期の止水時でも、抗菌性粉末 ５’の優れた制菌作用のためによく防止でき、悪臭の発生を回避できる。また、 水溶性物質膜には図４の（ロ）に示すように、切れ目ｃ，ｃを設けてあるので、 エア−リ−クテストも可能である。[0006] Therefore, due to the removal of the disinfectant by the granular activated carbon 7 ', the growth of the bacteria in the upper case piece 1', which is in a state where the bacteria are easily propagated, has an antibacterial property even when the water is stopped for a long time. Due to the excellent antibacterial action of the powder 5 ', it can be well prevented and the generation of a bad odor can be avoided. Further, since the water-soluble substance film is provided with the cuts c, c as shown in FIG. 4B, the air-leak test is also possible.
【０００７】[0007]
しかしながら、上記の水溶性物質膜５’を下部ケ−ス片１０’に張設するには 粘着剤を必要と、上記通水の開始後、この粘着剤が中空糸膜表面に付着し、初期 透水性能の低下が避けられない。 However, in order to stretch the above-mentioned water-soluble substance film 5'on the lower case piece 10 ', a pressure-sensitive adhesive is required. After the start of water flow, this pressure-sensitive adhesive adheres to the surface of the hollow fiber membrane, A decrease in water permeability is inevitable.
【０００８】 また、水溶性物質膜５１’の切れ目ｃ，ｃを余り大きくすると粒状活性炭５’ の漏出の防止が困難となり、他方、切れ目ｃ，ｃを細くすると、上記エア−リ− ク時のケ−ス内エア流れに対する抵抗が大となってエア−リ−クテストのエア圧 力を高くしなければならず、エアリ−クテストが困難になる。Further, if the cuts c, c of the water-soluble substance film 51 ′ are too large, it becomes difficult to prevent the granular activated carbon 5 ′ from leaking out. On the other hand, if the cuts c, c are thin, the above-mentioned air leak occurs. The resistance to the air flow in the case becomes large, and the air pressure of the air leak test must be increased, which makes the air leak test difficult.
【０００９】 本考案の目的は、抗菌性粉末を漏出しないように内蔵させるにもかかわらず、 初期透水量を充分に保証でき、エアリ−クテストも容易に行ない得る膜モジュ− ルを提供することにある。An object of the present invention is to provide a membrane module in which antibacterial powder is incorporated so as not to leak out, but the initial water permeation rate can be sufficiently ensured and the air leak test can be easily performed. is there.
【００１０】[0010]
本考案の膜モジュ−ルは袋入りの抗菌性粉末がモジュ−ルケ−ス内に納められ 、その袋が水溶性物質のみから成ることを特徴とする構成であり、膜には通常、 中空糸膜が用いられる。 The membrane module of the present invention is characterized in that a bag of antibacterial powder is contained in a module case, and the bag is made of only a water-soluble substance. The membrane is usually a hollow fiber. Membranes are used.
【００１１】[0011]
通水開始により袋が溶解して抗菌性粉末が膜面に付着し、膜面での雑菌の繁殖 が防止される。また、エア−リ−クテスト時でのリ−クに伴うケ−ス内のエア− 流れに対して袋入りの抗菌性粉末が抵抗として作用することがないから、エア− リ−クテストを通常通りに行ない得る。 When water starts flowing, the bag dissolves and the antibacterial powder adheres to the membrane surface, preventing the growth of bacteria on the membrane surface. In addition, since the bag-like antibacterial powder does not act as a resistance against the air flow in the case due to the leak during the air leak test, the air leak test is performed as usual. Get to.

以下、図面により本考案の実施例を説明する。 図１は本考案の実施例を示す説明図である。 図１において、１は上部ケ−ス片であり、上端に流出口２を備えている。３は 上部ケ−ス片内に収容した中空糸膜であり、各中空糸膜の上端をケ−ス内上部の 注型樹脂隔壁４の上面に開口させ、各中空糸膜の下端を樹脂等により封止してあ る。 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory view showing an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes an upper case piece, which has an outlet 2 at the upper end. 3 is a hollow fiber membrane housed in the upper case piece, the upper end of each hollow fiber membrane is opened to the upper surface of the casting resin partition wall 4 in the upper part of the case, and the lower end of each hollow fiber membrane is made of resin or the like. It is sealed by.
【００１３】 ５は袋入りの抗菌性粉末であり、袋は水溶性物質のみから作成してある。例え ば、図２に示すように、水溶性高分子フィルム（厚みは、通常２０〜３０μm)を 折り重ね、三方511,512,513を熱融着によりシ−ルして袋に作成したものを使用 できる。１０は下部ケ−ス片であり、流入口６を備えている。７は下部ケ−ス片 １０内に充填した粒状活性炭であり、上下の仕切り網７１，７２の間に充填して ある。８は上部ケ−ス片１と下部ケ−ス片１０との連結部であり、着脱自在とす ることもできる。Reference numeral 5 is an antibacterial powder contained in a bag, and the bag is made only of a water-soluble substance. For example, as shown in FIG. 2, it is possible to use a water-soluble polymer film (thickness is usually 20 to 30 μm) which is folded and sealed, and three sides 511, 512 and 513 are sealed by heat fusion to form a bag. A lower case piece 10 is provided with an inflow port 6. 7 is a granular activated carbon filled in the lower case piece 10 and is filled between the upper and lower partition nets 71 and 72. Reference numeral 8 denotes a connecting portion between the upper case piece 1 and the lower case piece 10, which can be detachable.
【００１４】 上記抗菌性粉末としては、抗菌作用を有する粉末であれば適宜のものを使用で きる。例えば、アルカリまたはアルカリ土類金属のアルミノ珪酸塩を骨格として 空洞を有する３〜１０Åの粒体に銅、銀、亜鉛等の抗菌性金属を含有させたもの を使用することができる。As the antibacterial powder, any powder can be used as long as it has an antibacterial effect. For example, 3 to 10 Å particles having a cavity of an aluminosilicate of an alkali or alkaline earth metal as a skeleton and containing an antibacterial metal such as copper, silver or zinc can be used.
【００１５】 また、抗菌性粉末量は膜モジュ−ルの膜面積に応じて定められ、通常膜面積１ ｍ2あたり１〜２０g或いは、モジュ−ルケ-ス内空間容積の０．１〜１０％の範 囲で選ばれる。The amount of antibacterial powder is determined according to the membrane area of the membrane module, and is usually 1 to 20 g per 1 m 2 of membrane area, or 0.1 to 10% of the space volume in the module case. Is selected within the range.
【００１６】 なお、粒状活性炭並びに網は省略することもできる。Note that the granular activated carbon and the net can be omitted.
【００１７】 上記の膜中空糸の使用にあたっては、エアリ−クテストを行なう必要がある。 このエアリ−クテストに対し、袋入り抗菌性粉末においては、エアリ−クがある 場合の空気の流れに対して実質上抵抗として作用することがないから、エア圧を 特に高圧とすることなく、エアリ−クテストを容易に行なうことができる。Before using the above membrane hollow fiber, it is necessary to perform an air leak test. In contrast to this air leak test, the bag-shaped antibacterial powder does not substantially act as a resistance to the air flow in the presence of air leak, so the air pressure does not need to be particularly high. -The test can be performed easily.
【００１８】 このエアリ−クテストの後に、給水栓に取り付けて使用される。給水を開始す ると、袋入りの抗菌性粉末の水溶性袋が溶解し、抗菌性粉末が中空糸膜の表面に 付着し、当該中空糸膜の表面が抗菌性粉末でコ−ティングされる。従って、長期 にわたる止水時でも、ケ−ス内の滞留水中での雑菌の繁殖を抗菌性粉末の優れた 制菌作用により阻止することができる。この結果、膜近傍での死菌の腐敗に起因 する異臭の発生を回避でき、清浄な雰囲気を保持できる。この場合、袋は完全に 溶解し、中空糸膜の目詰りを充分に回避できるから、優れた透水性能を保証でき る。After this air leak test, it is used by being attached to a water tap. When water supply is started, the water-soluble bag of antibacterial powder contained in the bag is dissolved, the antibacterial powder adheres to the surface of the hollow fiber membrane, and the surface of the hollow fiber membrane is coated with the antibacterial powder. .. Therefore, even when the water is stopped for a long time, it is possible to prevent the growth of various bacteria in the accumulated water in the case by the excellent antibacterial action of the antibacterial powder. As a result, it is possible to avoid the generation of offensive odor due to the spoilage of dead bacteria near the membrane, and it is possible to maintain a clean atmosphere. In this case, the bag is completely dissolved and the clogging of the hollow fiber membrane can be sufficiently avoided, so that excellent water permeability can be guaranteed.
【００１９】 このことは次ぎの試験結果からも確認できる。 試験 膜面積０．３ｍ2の中空糸膜モジュ−ルを使用し、膜面積１ｍ2あたりの抗菌性 粉末量を５gとし、これを水溶紙に粘着剤で付着させて用いた比較例と、同一水 溶紙を熱融着により袋状にし、この袋に上記と同量の抗菌性粉末を入れて使用し た本考案品とによって、カオリン懸濁液を濾過したところ、図３の通りであり、 本考案品よれば、初期透過水量を高くでき、かつ、目詰りの進行も充分に抑制で きた。This can be confirmed from the following test results. Test: A hollow fiber membrane module with a membrane area of 0.3 m 2 was used, and the amount of antibacterial powder per membrane area of 1 m 2 was 5 g. The kaolin suspension was filtered using a water-melt paper in the shape of a bag by heat fusion, and the bag of this invention containing the same amount of antibacterial powder as above was used. According to the product of the present invention, the initial permeated water amount can be increased and the progress of clogging can be sufficiently suppressed.
【００２０】[0020]
本考案の膜モジュ−ルは上述した通りの構成であり、抗菌性粉末を袋に入れて モジュ−ルのケ−ス内に収容してあるから、エアリ−クテスト時にエアリ−クが あったときのケ−ス内のエア流れに対して抗菌性粉末が抵抗として作用するよう なことがなく、エアリ−クテストを通常通り、容易に行ない得る。また、袋を水 溶性物質のみで作成しているから、袋材による膜の目詰りをよく回避でき、初期 透水量を充分に保証できる。 The membrane module of the present invention has the structure as described above, and since the antibacterial powder is put in a bag and housed in the case of the module, when there is an air leak during the air leak test. The antibacterial powder does not act as a resistance against the air flow in the case, and the air leak test can be easily performed as usual. In addition, since the bag is made of only water-soluble substances, it is possible to avoid clogging of the membrane with the bag material and to ensure a sufficient initial water permeability.
