Description

油捕集体Oil collector
　本発明は、料理で生じた廃水などに含まれる油を捕集する油捕集体に関する。 The present invention relates to an oil collector that collects oil contained in wastewater generated by cooking.
　家庭で料理をしていると、油と水等を含む廃水が発生することがある。これを流し台の排水口にそのまま流した場合、廃水に含まれる水が排水管に流入することについては環境衛生上の問題は特に生じないものの、油が排水管に流入することは環境衛生上好ましくないとされている。 When cooking at home, wastewater containing oil and water may be generated. If this is allowed to flow into the drain outlet of the sink as it is, there will be no environmental sanitation problems with regard to the water contained in the wastewater flowing into the drainpipe. It is said that there is no.
　従来、このような問題を解決する発明として、親油疎水性樹脂の繊維状物を細長棒状の塊状体にし、その塊状体をチップ状に切断した油吸着材が知られている（たとえば、特許文献１参照）。この油吸着材によれば、親油疎水性樹脂の繊維状物が素材に用いられているため、廃水に混入した油や油膜などを容易に除去することができる。 Conventionally, as an invention for solving such a problem, there has been known an oil adsorbent obtained by forming a fibrous body of a lipophilic hydrophobic resin into a long rod-like lump and cutting the lump into chips (for example, patents) Reference 1). According to this oil adsorbent, since the fibrous material of the lipophilic hydrophobic resin is used as the material, oil, an oil film, or the like mixed in the wastewater can be easily removed.
特開昭６１－１７１５９２号公報Japanese Patent Laid-Open No. 61-171592
　しかしながら、上述の油吸着材を構成する塊状体は、表面を熱処理した後に溶融固化して生成されるため、固化した表面での油吸着性が低下するという問題があった。
　また、上述の油吸着材は、チップ状に切断された塊状体を無規則に網袋に入れた状態で使用されるため、水がチップ間を通過しにくくなるという問題があった。さらに、シート状の繊維状物を用いて形成された密度の高い塊状体が素材として用いられるため、高い通水性を確保することは難しかった。
　本発明の目的は、油と水を含む液体から油のみを捕集して水を排出する高い油吸着性と通水性を備えた油捕集体を提供することである。 However, since the lump constituting the oil adsorbent described above is produced by melting and solidifying after heat-treating the surface, there is a problem that oil adsorbability on the solidified surface is lowered.
Moreover, since the above-mentioned oil adsorbent is used in a state where a lump cut into chips is randomly placed in a net bag, there is a problem that it is difficult for water to pass between the chips. Furthermore, since a high-density lump formed using a sheet-like fibrous material is used as a material, it has been difficult to ensure high water permeability.
An object of the present invention is to provide an oil collector having high oil adsorbability and water permeability that collects only oil from a liquid containing oil and water and discharges the water.
　本発明者は鋭意研究を重ねた結果、樹脂フィルムを紐状に皺めた油捕集素材を束ねて形成した油捕集体を用いることで、上記課題が解決することを見出した。
　すなわち、本発明の油捕集体は、
　樹脂フィルムを紐状に皺めて形成された複数の油捕集素材を含み、
　複数の前記油捕集素材が方向を揃えて束ねられることにより構成されていることを特徴とする。 As a result of intensive studies, the present inventor has found that the above problem can be solved by using an oil collecting body formed by bundling an oil collecting material in which a resin film is stringed.
That is, the oil collector of the present invention is
Including a plurality of oil collecting materials formed by stringing resin films
The plurality of oil collecting materials are configured by being bundled in the same direction.
　このように、樹脂フィルムを紐状に皺めることにより、油吸着性を向上させることができ、皺められた油捕集素材の方向を揃えて束ねることにより通水性を備えることができる。 Thus, by absorbing the resin film in a string shape, it is possible to improve the oil adsorbing property, and it is possible to provide water permeability by aligning and bundling the praised oil collecting material.
　また、本発明の油捕集体は、
　複数の前記油捕集素材が集束具により束ねられることを特徴とする。
　これにより、油捕集体の形状を的確に整えることができる。 The oil collector of the present invention is
A plurality of oil collecting materials are bundled by a bundling tool.
Thereby, the shape of an oil catcher can be adjusted exactly.
　また、本発明の油捕集体は、
　複数の前記油捕集素材の集束具への充填率が２．５ｖｏｌ％以上１４ｖｏｌ％未満であることを特徴とする。
　これにより、高い油吸着性と通水性を備えた油捕集体を提供することができる。 The oil collector of the present invention is
The filling ratio of the plurality of oil collecting materials into the bundling tool is 2.5 vol% or more and less than 14 vol%.
Thereby, the oil catcher provided with high oil adsorptivity and water permeability can be provided.
　また、本発明の油捕集体は、
　前記樹脂フィルムが、親油疎水性を有することを特徴とする。
　これにより、さらに油捕集体の油吸着性と通水性を向上させることができる。 The oil collector of the present invention is
The resin film has lipophilic hydrophobicity.

FIG. 1 is a diagram illustrating an oil collector according to an embodiment. As shown in FIG. 1, the oil collector 2 is configured by bundling a plurality of oil collection materials 4 made of a film resin gathered in a string shape in the same direction. Moreover, in order to bundle an oil collection raw material, the convergence tool 6 is used as needed. Hereinafter, the configuration of the oil collector 2, the method of using the oil collector 2, the method of creating the oil collector 2, and the like will be described in detail. In the present invention, the string shape means a shape that is elongated in one direction and can be easily bent.
〔１〕油捕集体の構成
（１）油捕集素材
　油捕集素材４に用いられる樹脂フィルムとしては、たとえば、ポリ塩化ビニリデン（以下、ＰＶＤＣという。）、ポリ塩化ビニル（以下、ＰＶＣという。）、ポリエステル、ポリオレフィン等のいわゆる親油疎水性樹脂を原料とするフィルムが用いられる。ポリオレフィンとしては、たとえば、ポリエチレン（以下、ＰＥという。）、ポリプロピレンが挙げられる。なお、樹脂フィルムには、可塑剤、安定剤、粘着剤、粘着付与剤、顔料、滑剤、抗酸化剤、フィラー、界面活性剤などの添加剤が配合されていてもよい。 [1] Configuration of Oil Collection Body (1) Oil Collection Material Examples of the resin film used for the oil collection material 4 include polyvinylidene chloride (hereinafter referred to as PVDC) and polyvinyl chloride (hereinafter referred to as PVC). ), Films made of so-called lipophilic hydrophobic resins such as polyester and polyolefin are used. Examples of the polyolefin include polyethylene (hereinafter referred to as PE) and polypropylene. The resin film may contain additives such as a plasticizer, a stabilizer, an adhesive, a tackifier, a pigment, a lubricant, an antioxidant, a filler, and a surfactant.
　上述の原料の中でも、ＰＶＤＣ、ＰＥ、ＰＶＣは、自己粘着性を有しているため、このいずれかで形成された油捕集素材４を束ねた場合には自律的に束なりが構成される。このため、油捕集素材４に用いられる樹脂フィルムとしては、ＰＶＤＣ、ＰＥ、ＰＶＣのいずれかを用いるのが好ましい。また、ＰＶＤＣ、ＰＥ、ＰＶＣの中でも特にＰＶＤＣは高い自己粘着性を有しているため、油捕集素材４に用いられる樹脂フィルムとしては、ＰＶＤＣを用いることはなお好ましい。 Among the above-mentioned raw materials, PVDC, PE, and PVC have self-adhesive properties, and therefore, when the oil collecting material 4 formed of any one of these is bundled, a bundle is formed autonomously. . For this reason, as a resin film used for the oil collection raw material 4, it is preferable to use either PVDC, PE, or PVC. Moreover, since PVDC has high self-adhesion among PVDC, PE, and PVC, it is still preferable to use PVDC as the resin film used for the oil collecting material 4.
　ここで、油捕集素材４の表面には、油吸着力を向上させる無数の皺４ａが形成されている。それぞれの皺４ａは、高い通水性を得るために油捕集素材４の長さ方向と略平行になるように形成されている。また、それぞれの油捕集素材４は、長さ方向を平行に揃えた状態で束ねられている。これにより、油捕集体２の円柱状の一方の端部を下方向に向けたときに端部から水が排出され易くなる。 Here, the surface of the oil collecting material 4 is formed with countless ridges 4a that improve the oil adsorbing power. Each trough 4a is formed so as to be substantially parallel to the length direction of the oil collecting material 4 in order to obtain high water permeability. Moreover, each oil collection raw material 4 is bundled in the state which aligned the length direction in parallel. Thereby, when one end part of the columnar shape of the oil collector 2 is directed downward, water is easily discharged from the end part.
（２）収束具
　収束具６としては、たとえば、図１に示すような、樹脂製の円筒状容器を用いることができる。この筒状容器に複数の油捕集素材４を収納することにより、複数の油捕集素材４が一方向に揃えて束ねられた円柱状の油捕集体２が形成される。また、収束具６は、底に複数の孔を開けた有底の筒状容器でもよい。その他、図２（ａ）、（ｂ）に示すように、収束具６としてバンド７等を用いて油捕集素材４を束ねてもよい。 (2) Converging tool As the converging tool 6, for example, a resin-made cylindrical container as shown in FIG. 1 can be used. By storing a plurality of oil collecting materials 4 in this cylindrical container, a cylindrical oil collecting body 2 in which a plurality of oil collecting materials 4 are bundled in one direction is formed. The converging tool 6 may be a bottomed cylindrical container having a plurality of holes in the bottom. In addition, as shown to Fig.2 (a), (b), you may bundle the oil collection raw material 4 using the band 7 etc. as the convergence tool 6. FIG.
〔２〕具体的な使用方法
　油捕集体２を使用する場所としては、台所の流しなどが考えられる。この場合、たとえば、図３に示すように、まず、三角コーナー９内に、底部に図示しない複数の小孔が形成された取手付き小容器１１を取り付ける。次に、円柱状の一方の端部が底部になるようにして油捕集体２を小容器１１の中に配置し、油捕集体２の上方から油と水を含む油水混合液から成る廃水を注入する。この場合、油捕集素材４が親油疎水性を有し、さらに油捕集素材４の表面に皺４ａが形成されていることから油吸着性が高められるため、廃水に含まれる油が油捕集素材４によって捕捉される。また、油捕集素材４が親油疎水性を有し、かつ油捕集素材４の皺４ａが上下方向に揃えられるため、廃水中の水は油捕集素材４に捕捉されず、皺４ａ間の隙間を通過して油捕集体２の底部から排出される。排出された水は、その後小容器１１底部の小孔を介して排水管に流れる。
　なお、油捕集体２を台所で使用する場合、油捕集体２の長さ（高さ）は、３ｃｍ以上３０ｃｍ以下であることが好ましい。 [2] Specific usage method As a place where the oil collector 2 is used, a kitchen sink or the like can be considered. In this case, for example, as shown in FIG. 3, first, a small container 11 with a handle in which a plurality of small holes (not shown) are formed in the bottom is attached in the triangular corner 9. Next, the oil collector 2 is placed in the small container 11 so that one end of the columnar shape becomes the bottom, and waste water composed of an oil-water mixture containing oil and water is disposed above the oil collector 2. inject. In this case, since the oil collection material 4 has lipophilic hydrophobicity and the ridge 4 a is formed on the surface of the oil collection material 4, the oil adsorption is improved, so that the oil contained in the wastewater is oil. It is captured by the collection material 4. Moreover, since the oil collection material 4 has lipophilicity and the ridge 4a of the oil collection material 4 is aligned in the vertical direction, the water in the wastewater is not captured by the oil collection material 4 and the ridge 4a It passes through the gap between them and is discharged from the bottom of the oil collector 2. The discharged water then flows to the drain pipe through a small hole at the bottom of the small container 11.
In addition, when using the oil collector 2 in a kitchen, it is preferable that the length (height) of the oil collector 2 is 3 cm or more and 30 cm or less.
〔３〕油捕集体の作成方法
　油捕集体２を作成する場合、まず、図４に示すように、ＰＶＤＣ、ＰＥ、ＰＶＣなどの樹脂フィルムがロール状に巻回されたフィルム原反１０とリング１２を用意する。ここで、フィルム原反１０には、幅が３０ｃｍ程度の市販されている樹脂フィルム１４が用いられる。また、リング１２には、たとえば中央に内径１５ｍｍの開口部１２ａを有する筒状の長さ１４ｍｍの金属製リングを用いる。なお、樹脂フィルム１４の厚さは、５μｍ以上４０μｍ以下であることが好ましい。 [3] Method for producing oil collector When producing the oil collector 2, first, as shown in FIG. 4, a raw film 10 and a ring in which a resin film such as PVDC, PE, or PVC is wound in a roll shape 12 is prepared. Here, as the original film 10, a commercially available resin film 14 having a width of about 30 cm is used. For the ring 12, for example, a cylindrical metal ring having a length of 14 mm and having an opening 12a having an inner diameter of 15 mm at the center is used. In addition, it is preferable that the thickness of the resin film 14 is 5 micrometers or more and 40 micrometers or less.
　次に、フィルム原反１０から樹脂フィルム１４を繰り出して窄め、リング１２の開口部１２ａを通過させて紐状に成形する。次に、この紐状に成形された樹脂フィルム１６を所定の長さにカットして油捕集素材４を作成する。この作業を繰り返すことにより、同じ長さの複数の油捕集素材４が得られる。 Next, the resin film 14 is drawn out from the original film 10 to be narrowed, and is passed through the opening 12a of the ring 12 and formed into a string shape. Next, the oil collecting material 4 is created by cutting the resin film 16 formed into a string shape into a predetermined length. By repeating this operation, a plurality of oil collecting materials 4 having the same length can be obtained.
　次に、複数の油捕集素材４を束ね、束ねた油捕集素材４を塩ビパイプ製の収束具６内に充填させることにより、同じ長さの油捕集素材４を束ねた油捕集体２が完成する（図１参照）。 Next, by bundling a plurality of oil collecting materials 4 and filling the bundled oil collecting materials 4 into a converging tool 6 made of a vinyl chloride pipe, an oil collecting body in which the oil collecting materials 4 of the same length are bundled. 2 is completed (see FIG. 1).
　ここで、束ねた油捕集素材４を収束具６内に充填させた場合における収束具６内の油捕集素材４の充填率（以下、フィルム充填率という。）は、以下の式で表される。
　フィルム充填率＝｛〔樹脂フィルムの厚さ（ｃｍ）×幅（ｃｍ）×長さ（ｃｍ）〕×油捕集素材の本数〕／〔（収束具の内径（ｃｍ）／２）2×円周率π×高さ（ｃｍ）〕｝×１００
　なお、充填率は、後述するように２．５ｖｏｌ％以上１４ｖｏｌ％未満であることが好ましい。 Here, when the bundled oil collecting material 4 is filled in the converging tool 6, the filling rate of the oil collecting material 4 in the converging tool 6 (hereinafter referred to as film filling rate) is expressed by the following equation. Is done.
Film filling rate = {[resin film thickness (cm) × width (cm) × length (cm)] × number of oil collecting materials] / [(inner diameter of converging tool (cm) / 2) 2 × circle Peripheral π × height (cm)]} × 100
In addition, it is preferable that a filling rate is 2.5 vol% or more and less than 14 vol% so that it may mention later.
　この実施の形態に係る発明によれば、油と水を含む液体から油のみを捕集して水を排出する高い油吸着性と通水性を備えた油捕集体を提供することができる。たとえば、台所の流しで油捕集体２を使用し、油捕集体２の上方から油と水を含む油水混合液を注いだ場合、油が油捕集素材４に吸着されて水だけが排出されるため、排水管に油が排出されず、流しの環境衛生を向上させることができる。また、フィルム原反１０には市販されている樹脂フィルムが用いられるため、油捕集体２は手軽に作成することができる。また、油捕集素材４は、従来例の塊状体を用いた油吸着材のように、煩雑な熱処理工程を経ることなく容易に製造することができる。 According to the invention according to this embodiment, it is possible to provide an oil collector having high oil adsorption and water permeability that collects only oil from a liquid containing oil and water and discharges the water. For example, when the oil collector 2 is used in a kitchen sink and an oil / water mixture containing oil and water is poured from above the oil collector 2, the oil is adsorbed by the oil collector 4 and only water is discharged. Therefore, oil is not discharged into the drain pipe, and the environmental sanitation of the sink can be improved. Moreover, since the commercially available resin film is used for the film original fabric 10, the oil collector 2 can be produced easily. Moreover, the oil collection material 4 can be easily manufactured without going through a complicated heat treatment step, like the oil adsorbent using the lump of the conventional example.
　以下に実施例を示し、本発明の実施の形態についてさらに詳しく説明する。もちろん、本発明は以下の実施例に限定されるものではなく、細部については様々な態様が可能であることはいうまでもない。 Examples will be shown below, and the embodiments of the present invention will be described in more detail. Of course, the present invention is not limited to the following examples, and it goes without saying that various aspects are possible in detail.
（油捕集量および油保持率の測定）
　油捕集体２が実際にどのくらいの捕集量の油を捕集し、また、捕集した油が所定の時間が経過した場合にどの程度放出されずに保持されるかについて、油捕集量および油保持率の測定を行った。以下に、具体的な測定方法を以下に示す。まず、油捕集素材４を作成するに当たっては、表１に示すように、ＰＶＤＣ製ラップ、ＰＥ製ラップ、およびＰＶＣ製ラップの３種類のフィルム原反１０を用意した。ここで、それぞれのフィルム原反１０は、いずれも市販されている樹脂フィルムである。 (Measurement of oil collection amount and oil retention)
How much oil is actually collected by the oil collector 2 and how much oil is collected without being released when a predetermined time has passed. And the oil retention was measured. A specific measurement method is shown below. First, in preparing the oil collecting material 4, as shown in Table 1, three types of film raw materials 10 of PVDC wrap, PE wrap, and PVC wrap were prepared. Here, each raw film 10 is a commercially available resin film.
Figure JPOXMLDOC01-appb-T000001
Figure JPOXMLDOC01-appb-T000001
　表１に示すように、いずれのフィルム原反１０も樹脂フィルムの幅が３０ｃｍのものを用いた。樹脂フィルムの厚さについては、ＰＶＤＣ製ラップが１０．５μｍ、ＰＥ製ラップが１０．８μｍ、ＰＶＣ製ラップが７．６μｍである。 As shown in Table 1, a film having a width of 30 cm was used for any of the original film 10. Regarding the thickness of the resin film, the PVDC wrap is 10.5 μm, the PE wrap is 10.8 μm, and the PVC wrap is 7.6 μm.
　これらの樹脂フィルムを用いて、上述した方法により、それぞれ長さ６ｃｍのＰＶＤＣ製の油捕集素材４、ＰＥ製の油捕集素材４、およびＰＶＣ製の油捕集素材４を作成した。次に、内径３ｃｍ、長さ６ｃｍ（Ｌ／Ｄ＝２）の円筒状の塩ビパイプから成る収束具６を用意し、図５に示すように、それぞれ複数の油捕集素材４を方向を揃えて収束具６に充填し、油捕集素材４が収束具６に収束された油捕集ユニット３を作成した。ここで、作成された油捕集ユニット３は、ＰＶＤＣ製の油捕集素材４を充填した油捕集ユニット（以下、ＰＶＤＣ油捕集ユニットという。）、ＰＥ製の油捕集素材４を充填した油捕集ユニット（以下、ＰＥ油捕集ユニットという。）、ＰＶＣ製の油捕集素材４を充填した油捕集ユニット（以下、ＰＶＣ油捕集ユニットという。）である。なお、ＰＶＤＣ油捕集ユニット、ＰＥ油捕集ユニット、ＰＶＣ油捕集ユニットのいずれについても、油捕集素材４の充填率が異なる４タイプのものを作成した（表２参照）。 Using these resin films, an oil collecting material 4 made of PVDC, an oil collecting material 4 made of PE, and an oil collecting material 4 made of PVC were prepared by the method described above. Next, a converging tool 6 made of a cylindrical polyvinyl chloride pipe having an inner diameter of 3 cm and a length of 6 cm (L / D = 2) is prepared. As shown in FIG. 5, a plurality of oil collecting materials 4 are aligned in directions. Thus, the oil collecting unit 3 was prepared by filling the converging tool 6 and having the oil collecting material 4 converged on the converging tool 6. Here, the created oil collection unit 3 is filled with an oil collection unit (hereinafter referred to as a PVDC oil collection unit) filled with an oil collection material 4 made of PVDC, and an oil collection material 4 made of PE. An oil collecting unit (hereinafter referred to as a PE oil collecting unit), and an oil collecting unit (hereinafter referred to as a PVC oil collecting unit) filled with an oil collecting material 4 made of PVC. For all of the PVDC oil collecting unit, the PE oil collecting unit, and the PVC oil collecting unit, four types having different filling rates of the oil collecting material 4 were created (see Table 2).
　次に、図６（ａ）に示すように、まず、測定前の油捕集ユニット３の重量（Ｍｕ［ｇ］）を計測した。次に、図６（ｂ）に示すように、日清オイリオグループ(株)製の食用調合油（以下、サラダ油という。）で満たされた容器を用意し、サラダ油に油捕集ユニット３を浸漬した。ここで、油捕集ユニット３は、錘を用いるなどしてサラダ油に完全に沈むようにした。次に、図６（ｃ）に示すように、サラダ油に浸漬してから２４時間後に油捕集ユニット３を取り出し、油切後の油捕集ユニット３の重量（Ｍｕ´［ｇ］）を計測した。油捕集ユニット３の重量の計測は、０．５時間油切りを行った後、および２４時間油切りを行った後にそれぞれ行った。なお、油切りは、収束具６から油捕集素材４が脱落しないように金網２０上で行った。 Next, as shown in FIG. 6A, first, the weight (Mu [g]) of the oil collecting unit 3 before measurement was measured. Next, as shown in FIG. 6 (b), a container filled with edible oil composition (hereinafter referred to as salad oil) manufactured by Nisshin Oillio Group Co., Ltd. is prepared, and the oil collecting unit 3 is immersed in the salad oil. did. Here, the oil collecting unit 3 was completely submerged in the salad oil by using a weight or the like. Next, as shown in FIG. 6C, the oil collecting unit 3 is taken out 24 hours after being immersed in the salad oil, and the weight (Mu ′ [g]) of the oil collecting unit 3 after draining is measured. did. The weight of the oil collecting unit 3 was measured after deoiling for 0.5 hours and after deoiling for 24 hours. The oil draining was performed on the wire mesh 20 so that the oil collecting material 4 did not fall off from the converging tool 6.
　次に、油切前後の油捕集ユニット３の重量差を計算し、計算結果を基に、油切後０．５時間が経過した油捕集ユニット３に充填された樹脂フィルム１ｇあたりの油捕集量、および油切後２４時間が経過した油捕集ユニット３に充填された樹脂フィルム１ｇあたりの油捕集量を算出した。なお、油捕集量を計算する際には、ＰＶＤＣ製の樹脂フィルムの密度を１．６５（ｇ／ｃｍ3）、ＰＥ製の樹脂フィルムの密度を０．９１（ｇ／ｃｍ3）、ＰＶＣ製の樹脂フィルムの密度を１．２２（ｇ／ｃｍ3）として計算した。 Next, the difference in weight of the oil collecting unit 3 before and after draining is calculated, and based on the calculation result, the oil per 1 g of the resin film filled in the oil collecting unit 3 that has passed 0.5 hours after draining. The amount of oil collected and the amount of oil collected per 1 g of the resin film filled in the oil collecting unit 3 after 24 hours had elapsed after draining were calculated. When calculating the amount of oil collected, the density of the PVDC resin film is 1.65 (g / cm 3 ), the density of the PE resin film is 0.91 (g / cm 3 ), PVC The density of the manufactured resin film was calculated as 1.22 (g / cm 3 ).
　油捕集量を計算する際の算出式は以下のとおりである。
　〔１〕　油捕集素材４の体積（ｃｍ3）＝（樹脂フィルムの幅（ｃｍ））×（油捕集素材４の長さ（ｃｍ））×（樹脂フィルム１４の厚さ（ｃｍ））
　〔２〕　油捕集体２の体積（ｃｍ3）＝（油捕集素材４の体積（ｃｍ3））×（油捕集素材の本数）
　〔３〕　油捕集体２の重量（ｇ）＝（油捕集体２の体積（ｃｍ3））×（樹脂フィルムの密度（ｇ／ｃｍ3））
　〔４〕　油捕集ユニット３の油捕集量（ｇ）＝（油切後の油捕集ユニット３の重量（ｇ））－（測定前の油捕集ユニット３の重量（ｇ））
　〔５〕　樹脂フィルム１ｇあたりの油捕集量（ｇ／ｇ）＝（油捕集ユニット３の油捕集量（ｇ））／（油捕集体２の重量（ｇ）） The formula for calculating the amount of oil collected is as follows.
[1] Volume of oil collecting material 4 (cm 3 ) = (width of resin film (cm)) × (length of oil collecting material 4 (cm)) × (thickness of resin film 14 (cm))
[2] Volume of oil collector 2 (cm 3 ) = (volume of oil collector 4 (cm 3 )) × (number of oil collectors)
[3] Weight of oil collector 2 (g) = (volume of oil collector 2 (cm 3 )) × (density of resin film (g / cm 3 ))
[4] Oil collection amount of oil collection unit 3 (g) = (weight of oil collection unit 3 after draining oil (g)) − (weight of oil collection unit 3 before measurement (g))
[5] Oil collection amount per 1 g of resin film (g / g) = (oil collection amount of oil collection unit 3 (g)) / (weight of oil collection body 2 (g))
　また、油切後０．５時間が経過した油捕集ユニット３の油捕集量と油切後２４時間が経過した油捕集ユニット３の油捕集量を基に、油捕集ユニット１個当たりの油保持率を算出した。油保持率を計算する際の算出式は以下のとおりである。
　油保持率（％）＝［油切後２４時間が経過した後の油捕集ユニットの油捕集量（ｇ）／油切後０．５時間が経過した油捕集ユニットの油捕集量（ｇ）］×１００ Further, the oil collecting unit 1 is based on the oil collecting amount of the oil collecting unit 3 that has passed 0.5 hours after draining and the oil collecting amount of the oil collecting unit 3 that has passed 24 hours after draining. The oil retention per unit was calculated. The calculation formula for calculating the oil retention is as follows.
Oil retention rate (%) = [Oil collection amount of oil collection unit after 24 hours have passed after draining oil (g) / Oil collection amount of oil collection unit after 0.5 hours after draining (G)] × 100
（油捕集量および油保持率の測定結果）
　図７は、油捕集量の測定において観測された樹脂フィルム充填率と油捕集量の関係を示すグラフである。ここで、グラフの縦軸は樹脂フィルム１ｇあたりの油捕集量を示し、グラフの横軸はフィルム充填率を示している。図７に示すグラフによれば、ＰＶＤＣ油捕集ユニット（ＰＶＤＣ）、およびＰＥ油捕集ユニット（ＰＥ）は、フィルム充填率が４．５ｖｏｌ％近傍のときに油捕集量が最大となり、ＰＶＣ油捕集ユニット（ＰＶＣ）は、フィルム充填率が２．３ｖｏｌ％近傍のときに油捕集量が最大となることがわかる。 (Measurement results of oil collection and oil retention)
FIG. 7 is a graph showing the relationship between the resin film filling rate and the oil collection amount observed in the measurement of the oil collection amount. Here, the vertical axis of the graph indicates the amount of oil collected per 1 g of the resin film, and the horizontal axis of the graph indicates the film filling rate. According to the graph shown in FIG. 7, the PVDC oil collection unit (PVDC) and the PE oil collection unit (PE) have the maximum oil collection amount when the film filling rate is around 4.5 vol%. It can be seen that the oil collecting unit (PVC) has the maximum oil collecting amount when the film filling rate is around 2.3 vol%.
　図８は、油捕集量の測定において観測された油捕集量の経時変化を示すグラフである。ここで、図８（ａ）は、ＰＶＤＣ油捕集ユニットの経時変化を示し、図８（ｂ）は、ＰＥ油捕集ユニットの経時変化を示し、図８（ｃ）は、ＰＶＣ油捕集ユニットの経時変化を示している。また、各々のグラフの縦軸は樹脂フィルム１ｇあたりの油捕集量を示し、グラフの横軸は油切り時間を示している。なお、油切り時間は対数で示されている。 FIG. 8 is a graph showing the change over time in the amount of oil collected observed in the measurement of the amount of oil collected. Here, FIG. 8 (a) shows the change over time of the PVDC oil collection unit, FIG. 8 (b) shows the change over time of the PE oil collection unit, and FIG. 8 (c) shows the PVC oil collection. The change with time of the unit is shown. Moreover, the vertical axis | shaft of each graph showed the oil collection amount per 1g of resin films, and the horizontal axis of the graph has shown the oil removal time. The oil draining time is shown in logarithm.
　図８（ａ）は、フィルム充填率２．２ｖｏｌ％、４．５ｖｏｌ％、１３．４ｖｏｌ％、２２．３ｖｏｌ％のそれぞれのＰＶＤＣ油捕集ユニットについて、油切り時間を経過させながら測定した樹脂フィルム１ｇあたりの油捕集量（ｇ／ｇ）の測定結果を示している。図８（ａ）に示す測定結果によれば、フィルム充填率の小さい（２．２ｖｏｌ％、４．５ｖｏｌ％）ＰＶＤＣ油捕集ユニットについては、油切り時間が経過するにつれて捕集されたサラダ油が減少していることがわかる。一方、フィルム充填率の大きい（１３．４ｖｏｌ％、２２．３ｖｏｌ％）ＰＶＤＣ油捕集ユニットについては、油切り時間が経過しても捕集されたサラダ油はほとんど減少していないことがわかる。 FIG. 8A is a resin film measured for each PVDC oil collecting unit having a film filling rate of 2.2 vol%, 4.5 vol%, 13.4 vol%, and 22.3 vol% while passing the oil removal time. The measurement result of the amount of oil collected per gram (g / g) is shown. According to the measurement results shown in FIG. 8 (a), for the PVDC oil collecting unit having a small film filling rate (2.2 vol%, 4.5 vol%), the salad oil collected as the oil removal time elapses. It turns out that it is decreasing. On the other hand, about the PVDC oil collection unit with a large film filling rate (13.4 vol%, 22.3 vol%), it can be seen that the collected salad oil is hardly decreased even after the oil removal time has elapsed.
　図８（ｂ）は、フィルム充填率２．３ｖｏｌ％、４．６ｖｏｌ％、１３．８ｖｏｌ％、２２．９ｖｏｌ％のそれぞれのＰＥ油捕集ユニットについて、油切り時間を経過させながら測定した樹脂フィルム１ｇあたりの油捕集量（ｇ／ｇ）の測定結果を示している。図８（ｂ）に示す測定結果によれば、ＰＥ油捕集ユニットもＰＶＤＣ油捕集ユニットと同様に、フィルム充填率の小さい（２．３ｖｏｌ％、４．６ｖｏｌ％）ＰＥ油捕集ユニットについては、油切り時間が経過するにつれて捕集されたサラダ油が減少し、フィルム充填率の大きい（１３．８ｖｏｌ％、２２．９ｖｏｌ％）ＰＥ油捕集ユニットについては、油切り時間が経過しても捕集されたサラダ油はほとんど減少していないことがわかる。 FIG. 8 (b) shows a resin film measured for each PE oil collecting unit having a film filling rate of 2.3 vol%, 4.6 vol%, 13.8 vol%, and 22.9 vol% while passing the oil removal time. The measurement result of the amount of oil collected per gram (g / g) is shown. According to the measurement results shown in FIG. 8 (b), the PE oil collecting unit is also similar to the PVDC oil collecting unit with respect to the PE oil collecting unit having a small film filling rate (2.3 vol%, 4.6 vol%). In the case of a PE oil collecting unit having a large film filling rate (13.8 vol%, 22.9 vol%), the collected salad oil decreases as the oil draining time elapses. It can be seen that the collected salad oil has hardly decreased.
　図８（ｃ）は、フィルム充填率１．６ｖｏｌ％、３．２ｖｏｌ％、９．７ｖｏｌ％、１６．１ｖｏｌ％のそれぞれのＰＶＣ油捕集ユニットについて、油切り時間を経過させながら測定した樹脂フィルム１ｇあたりの油捕集量（ｇ／ｇ）の測定結果を示している。図８（ｃ）に示す測定結果もまた、図８（ａ）、（ｂ）に示す測定結果と同様に、フィルム充填率の小さい（１．６ｖｏｌ％、３．２ｖｏｌ％）ＰＶＣ油捕集ユニットについては、油切り時間が経過するにつれて捕集されたサラダ油が減少し、フィルム充填率の大きい（９．７ｖｏｌ％、１６．１ｖｏｌ％）ＰＶＣ油捕集ユニットについては、油切り時間が経過しても捕集されたサラダ油はほとんど減少していないことがわかる。 FIG.8 (c) is the resin film measured while passing oil removal time about each PVC oil collection unit with a film filling rate of 1.6 vol%, 3.2 vol%, 9.7 vol%, and 16.1 vol%. The measurement result of the amount of oil collected per gram (g / g) is shown. The measurement results shown in FIG. 8 (c) are also the same as the measurement results shown in FIGS. 8 (a) and 8 (b). The PVC oil collecting unit has a small film filling rate (1.6 vol%, 3.2 vol%). For the PVC oil collection unit with a large film filling rate (9.7 vol%, 16.1 vol%), the oil drainage time has passed, as the oil removal time has passed and the collected salad oil has decreased. It can be seen that the collected salad oil has hardly decreased.
　上述の測定に用いた油捕集ユニットの諸元と測定結果を表２に示す。表２によれば、ＰＶＤＣ油捕集ユニットとＰＶＣ油捕集ユニット、は、フィルム充填率を４．５ｖｏｌ％とした場合に油捕集量が最大となり、ＰＥ油捕集ユニットは、フィルム充填率を４．６ｖｏｌ％とした場合に樹脂フィルム１ｇあたりの油捕集量が最大となることがわかった。 Table 2 shows the specifications and measurement results of the oil collection unit used for the above measurement. According to Table 2, the PVDC oil collection unit and the PVC oil collection unit have the maximum oil collection amount when the film filling rate is 4.5 vol%, and the PE oil collection unit has the film filling rate. It was found that the amount of oil collected per 1 g of the resin film was maximized when the amount was 4.6 vol%.
　また、油保持率については、充填率１３～２２ｖｏｌ％の充填率の高い油捕集ユニットにおいて油保持率が高くなる傾向が見られた。 As for the oil retention rate, there was a tendency for the oil retention rate to increase in an oil collecting unit with a high filling rate of 13 to 22 vol%.

（濾過速度および油漏れの評価）
　次に、油捕集体２が実際にどの程度水を透過し、油を透過させずに保持するかについて検証すべく、濾過速度と油漏れの測定を行った。以下、具体的な測定方法を説明する。まず、図９（ａ）に示すように、５０ｇのサラダ油が貯留されたビーカー（容量２００ｍｌ）と、Aldrich Chemical Company, Inc.製アゾ染料C.I.ソルベントレッド（以下、アゾ染料と略す。）を用意した。アゾ染料は、油に溶解し、水に溶解しない性質を有している。次に、ビーカー内のサラダ油にアゾ染料の粉末５ｍｇを混合し、ガラス棒でこれを攪拌してサラダ油にアゾ染料の粉末を溶解させ、サラダ油を赤色に染色して油漏れを判別しやすいようにした。 (Evaluation of filtration speed and oil leakage)
Next, in order to verify how much water the oil collector 2 actually permeates and retains without permeating the oil, the filtration rate and the oil leakage were measured. Hereinafter, a specific measurement method will be described. First, as shown in FIG. 9A, a beaker (capacity 200 ml) storing 50 g of salad oil and an azo dye CI solvent red (hereinafter abbreviated as azo dye) manufactured by Aldrich Chemical Company, Inc. were prepared. . Azo dyes have the property of being soluble in oil and not soluble in water. Next, 5 mg of azo dye powder is mixed with the salad oil in the beaker, and this is stirred with a glass rod to dissolve the azo dye powder in the salad oil, and the salad oil is dyed red so that oil leakage can be easily identified. did.
　次に、図９（ｂ）に示すように、ビーカー（容量１００ｍｌ）を用意し、ビーカー内で赤色に染色させたサラダ油３ｇと蒸留水３０ｍｌをガラス棒で攪拌して混合し油水混合液を作成した。 Next, as shown in FIG. 9B, a beaker (capacity 100 ml) is prepared, and 3 g of salad oil dyed red in the beaker and 30 ml of distilled water are mixed with stirring with a glass rod to create an oil-water mixture. did.
　次に、図１０（ａ）に示すように、上述の油捕集量および油保持率の測定に用いたのと同じ油捕集体２を長さ１８ｃｍの樹脂製筒状の収束具６内に配置させた油捕集用具２４を作成した。ここで、油捕集体２を油捕集用具２４の下方に配置することにより、油捕集体２の上部に油水混合液を貯留する空間２４ａを形成した。なお、油捕集用具２４としては、ＰＶＤＣ製の樹脂フィルムを用いた油捕集体２を収束具６内に配置させた油捕集用具（以下、ＰＶＤＣ油捕集用具という。）、ＰＥ製の樹脂フィルムを用いた油捕集体２を収束具６内に配置させた油捕集用具（以下、ＰＥ油捕集用具という。）、ＰＶＣ製の樹脂フィルムを用いた油捕集体２を収束具６内に配置させた油捕集用具（以下、ＰＶＣ油捕集用具という。）を作成した。また、それぞれの各油捕集用具はフィルム充填率の異なる４タイプのものを作成した（表３参照）。 Next, as shown in FIG. 10 (a), the same oil collector 2 used for the measurement of the amount of oil collected and the oil retention rate described above is placed in a resin cylindrical converging tool 6 having a length of 18 cm. The arranged oil collecting tool 24 was created. Here, by arranging the oil collecting body 2 below the oil collecting tool 24, a space 24 a for storing the oil / water mixture is formed in the upper part of the oil collecting body 2. In addition, as the oil collection tool 24, the oil collection tool (henceforth a PVDC oil collection tool) which made the oil collection body 2 using the resin film made from PVDC arrange | positioned in the convergence tool 6, and the product made from PE. An oil collecting tool (hereinafter referred to as PE oil collecting tool) in which an oil collecting body 2 using a resin film is disposed in a converging tool 6, and an oil collecting body 2 using a PVC resin film are used as the converging tool 6. The oil collection tool (henceforth a PVC oil collection tool) arrange | positioned inside was created. Moreover, each type of oil collecting tool produced four types with different film filling rates (see Table 3).
　ここで、直ちに空間２４ａに油水混合液を注入すると、油捕集体２に水がトラップされてしまうため、事前に油捕集体２に蒸留水を十分に浸透させた。具体的には、図１０（ｂ）に示すように、空間２４ａに蒸留水１００ｍｌを注入して油捕集体２に蒸留水を十分に浸透させ、その後約５分放置し、油捕集体２が保持しきれない水を三角漏斗（６０ｍｍφ）を介してビーカー（容量２００ｍｌ）に排出した。なお、図中に示される金網２０は、上述した油切りの場合と同様に、油捕集用具２４から油捕集体２を脱落させないように用意したものである。 Here, when the oil / water mixture was immediately poured into the space 24a, water was trapped in the oil collector 2, so that the oil collector 2 was sufficiently infiltrated with distilled water in advance. Specifically, as shown in FIG. 10 (b), 100 ml of distilled water is injected into the space 24a to sufficiently infiltrate the distilled water into the oil collector 2, and then left for about 5 minutes. Water that could not be retained was discharged into a beaker (capacity 200 ml) through a triangular funnel (60 mmφ). In addition, the wire mesh 20 shown in the figure is prepared so that the oil collecting body 2 is not dropped from the oil collecting tool 24 as in the case of the oil removal described above.
　次に、図１１に示すように、通水後の油捕集用具２４に油水混合液を注水して濾過時間の測定を行った。ここで、濾過時間とは、油捕集用具２４に注水された油水混合液に含まれる水の９５％が排出されるまでにかかる時間である。この濾過時間を基に通水速度が速いか遅いかについて濾過速度の評価を行った。また、メスシリンダー３２に貯留された排水を目視観察することにより油漏れの度合の評価を行った。 Next, as shown in FIG. 11, the oil / water mixture was poured into the oil collecting tool 24 after passing water, and the filtration time was measured. Here, the filtration time is the time taken for 95% of the water contained in the oil / water mixture poured into the oil collecting tool 24 to be discharged. Based on this filtration time, the filtration rate was evaluated as to whether the water flow rate was fast or slow. Further, the degree of oil leakage was evaluated by visually observing the wastewater stored in the graduated cylinder 32.
　上述の濾過速度と油漏れについての評価結果を表３に示す。なお、濾過速度の評価は○、△、×の三段階の基準で評価した。○は濾過速度が速い（１０秒未満）という評価であり、△は濾過速度がやや遅い（１０秒以上３０秒未満）という評価であり、×は濾過速度が遅い（３０秒以上）という評価である。また、油漏れの評価もまた○、△、×の三段階の基準で評価した。○は油漏れがほとんどないという評価であり、△は油漏れが若干ある評価であり、×は油漏れが多い評価である。 Table 3 shows the evaluation results for the filtration rate and oil leakage described above. The filtration rate was evaluated based on the three-stage criteria of ○, Δ, and ×. ○ is an evaluation that the filtration rate is fast (less than 10 seconds), △ is an evaluation that the filtration rate is slightly slow (from 10 seconds to less than 30 seconds), and × is an evaluation that the filtration rate is slow (more than 30 seconds). is there. Moreover, the evaluation of oil leakage was also evaluated based on three-stage criteria of ○, Δ, and ×. ○ is evaluation that there is almost no oil leakage, Δ is evaluation that there is some oil leakage, and × is evaluation that there is much oil leakage.

　表３によれば、ＰＶＤＣ油捕集用具については、フィルム充填率を２．２ｖｏｌ％とした場合には、水をほぼ素通しすることとなり、濾過時間が５秒以下（濾過速度：○）となった。この場合、メスシリンダーを目視するとアゾ染料の赤色が観察され、若干の油漏れがある（油漏れ：△）ことがわかった。 According to Table 3, for the PVDC oil collecting tool, when the film filling rate is 2.2 vol%, water is almost passed through, and the filtration time is 5 seconds or less (filtration rate: ◯). It was. In this case, when the graduated cylinder was visually observed, the red color of the azo dye was observed, and it was found that there was a slight oil leak (oil leak: Δ).
　フィルム充填率を４．５ｖｏｌ％とした場合も、水をほぼ素通しするため濾過時間が５秒以下（濾過速度：○）となり、油漏れもほとんどなかった（油漏れ：○）。フィルム充填率を１３．４ｖｏｌ％とした場合は、油漏れはほとんどないものの（油漏れ：○）濾過時間が２６秒となり（濾過速度：△）、フィルム充填率を２２．３ｖｏｌ％とした場合もまた、油漏れはほとんどないものの（油漏れ：○）濾過時間は８４秒となった（濾過速度：×）。以上によれば、フィルム充填率を４．５ｖｏｌ％とした場合にのみ濾過速度と油漏れの評価が共に良好であった。 Even when the film filling rate was 4.5 vol%, since water was almost passed through, the filtration time was 5 seconds or less (filtration rate: ○), and there was almost no oil leakage (oil leakage: ○). When the film filling rate is 13.4 vol%, there is almost no oil leakage (oil leakage: ○), the filtration time is 26 seconds (filtration rate: Δ), and the film filling rate is 22.3 vol%. Moreover, although there was almost no oil leak (oil leak: (circle)), the filtration time was 84 seconds (filtration rate: x). According to the above, both the filtration rate and the oil leakage evaluation were good only when the film filling rate was 4.5 vol%.
　ＰＥ油捕集用具においては、フィルム充填率を４．５ｖｏｌ％とした場合に濾過速度と油漏れの双方について最も良好な評価が得られ、ＰＶＣ油捕集用具においては、フィルム充填率を４．６ｖｏｌ％とした場合に濾過速度と油漏れの双方について最も良好な評価が得られた。 In the PE oil collecting tool, when the film filling rate is 4.5 vol%, the best evaluation is obtained for both the filtration rate and the oil leakage. In the PVC oil collecting tool, the film filling rate is 4. In the case of 6 vol%, the best evaluation was obtained for both the filtration rate and oil leakage.
　表４は、油捕集量、油保持率、濾過速度、油漏れの４つの項目の測定結果または評価結果についてまとめた表である。表４によれば、油捕集体２のフィルム充填率は、２．５～１４ｖｏｌ％の範囲が好ましく、特に４．５ｖｏｌ％とすることが好ましいことがわかる。 Table 4 is a table summarizing the measurement results or evaluation results of the four items of oil collection amount, oil retention rate, filtration speed, and oil leakage. According to Table 4, it can be seen that the film filling rate of the oil collector 2 is preferably in the range of 2.5 to 14 vol%, and particularly preferably 4.5 vol%.

　また、上述の実施の形態において、油捕集体２を台所で使用する場合、図１２（ａ）に示すように、三角コーナー９内に油捕集体２を配置し、油捕集体２が配置された三角コーナー９の上にさらに三角コーナー９´を重ねてもよい。ここで、三角コーナー９´には図示しない水切り袋が被せられている。また、三角コーナー９、９´のいずれの底部にも図示しない複数の小孔が形成されている。この場合、油水混合液である廃水を三角コーナー９´に流すと、まず、廃水に混入している粗ゴミなどが水切り袋で捕捉される。そして、三角コーナー９´底部の小孔から排出された廃水が油捕集体２に注入され、廃水中の油は油捕集体２に捕捉され、水は油捕集体２から排出される。水は、その後三角コーナー９底部の小孔を介して排水管に流れる。 Moreover, in the above-mentioned embodiment, when using the oil collector 2 in a kitchen, as shown in FIG. 12A, the oil collector 2 is disposed in the triangular corner 9, and the oil collector 2 is disposed. A triangular corner 9 ′ may be further superimposed on the triangular corner 9. Here, a draining bag (not shown) is put on the triangular corner 9 '. A plurality of small holes (not shown) are formed at the bottom of each of the triangular corners 9 and 9 '. In this case, when waste water that is an oil / water mixture is passed through the triangular corner 9 ′, first, coarse dust mixed in the waste water is captured by the draining bag. Then, the wastewater discharged from the small hole at the bottom of the triangular corner 9 ′ is injected into the oil collector 2, the oil in the wastewater is captured by the oil collector 2, and the water is discharged from the oil collector 2. The water then flows into the drain through a small hole at the bottom of the triangular corner 9.
　また、図１２（ｂ）に示すように、三角コーナー９の底を二重底にし、下底に油捕集体２を配置してもよい。ここで、三角コーナー９の二重底にはいずれも複数の小孔が形成されている。また、この場合も二重底の三角コーナー９には水切り袋を被せておく。この場合においても、油水混合液に混入している粗ゴミなどを水切り袋で捕捉される。また、廃水中の油が油捕集体２に捕捉され、水が油捕集体２から排出されて排水管に流れる。 Further, as shown in FIG. 12 (b), the bottom of the triangular corner 9 may be a double bottom, and the oil collector 2 may be disposed on the lower bottom. Here, a plurality of small holes are formed in the double bottom of the triangular corner 9. In this case, the double-bottom triangular corner 9 is covered with a draining bag. Even in this case, coarse dust or the like mixed in the oil / water mixture is captured by the draining bag. Further, oil in the wastewater is captured by the oil collector 2, and water is discharged from the oil collector 2 and flows into the drain pipe.
　また、油捕集体２をたとえば一斗缶サイズに形成し、中華料理店などで業務用に用いてもよい。この場合、使用者は、バンドなどで集束された一斗缶サイズの油捕集体２を掴んで、厨房内に付着した油水混合液に底面を浸漬させる。ここで、油捕集素材４の表面に形成された皺４ａは、毛管現象によって油を吸収する性質を有することから、厨房内に付着した油水混合液の油分が水と分離されて油捕集体２に吸収され、厨房内の油汚れを取り除くことができる。 Also, the oil collector 2 may be formed in a size of, for example, a can, and used for business purposes in a Chinese restaurant or the like. In this case, the user holds the oil collecting body 2 having the size of a canister that is focused with a band or the like, and immerses the bottom surface in the oil / water mixture adhering to the kitchen. Here, since the ridge 4a formed on the surface of the oil collecting material 4 has a property of absorbing oil by capillary action, the oil component of the oil / water mixture adhering to the kitchen is separated from the water to collect the oil collecting body. 2 absorbs oil stains in the kitchen.
　また、上述の実施の形態においては、油捕集体２を作成する際に、リング１２の開口部１２ａに樹脂フィルムを通過させて紐状に成形する場合を例に説明しているが、図１３に示すようにフィルム原反１０の内径から樹脂フィルムが巻回されている方向と直交する方向に樹脂フィルム１６を引き出してカットし、紐状の油捕集素材を得るようにしてもよい。 Further, in the above-described embodiment, when the oil collector 2 is created, the case where the resin film is passed through the opening 12a of the ring 12 and formed into a string shape is described as an example. As shown, the resin film 16 may be pulled out from the inner diameter of the original film 10 in a direction orthogonal to the direction in which the resin film is wound and cut to obtain a string-like oil collecting material.
　また、上述の実施の形態において、油捕集体２の形状は、円柱を変形させた略円柱状であってもよい。たとえば、図１４（ａ）に示すように斜円柱状でもよく、図１４（ｂ）に示すように斜切円柱状でもよい。 Further, in the above-described embodiment, the shape of the oil collector 2 may be a substantially columnar shape obtained by deforming a column. For example, an oblique cylindrical shape may be used as shown in FIG. 14A, and an obliquely cut cylindrical shape may be used as shown in FIG.
　また、油捕集体２の形状は、樹脂フィルムを皺めて形成された紐状の油捕集素材４を束ねたものであれば円柱状でなくてもよい。たとえば、図１４（ｃ）に示すように三角柱状でもよく、図１４（ｄ）に示すように四角柱状でもよい。また、図１４（ｅ）に示すように底面が台形の四角柱状でもよい。さらに、図１４（ｆ）に示すように五角柱状でもよく、図１４（ｇ）に示すように六角柱状でもよい。油捕集体２の形状を角柱状とする場合には、図１４（ｈ）～（ｌ）に示すように、油捕集体２を傾斜させてもよい。また、油捕集体２は、図１４（ｍ）～（ｐ）に示すような底面を有する複雑な形状を有していてもよい。 Also, the shape of the oil collecting body 2 may not be cylindrical as long as it is a bundle of string-like oil collecting materials 4 formed by holding a resin film. For example, a triangular prism shape may be used as shown in FIG. 14C, or a quadrangular prism shape may be used as shown in FIG. Moreover, as shown in FIG.14 (e), trapezoidal square pillar shape may be sufficient as a bottom face. Furthermore, it may be a pentagonal column as shown in FIG. 14 (f) or a hexagonal column as shown in FIG. 14 (g). When the shape of the oil catcher 2 is a prism, the oil catcher 2 may be inclined as shown in FIGS. 14 (h) to (l). Further, the oil collector 2 may have a complicated shape having a bottom surface as shown in FIGS. 14 (m) to 14 (p).
　また、油捕集素材４は、原則としては、図１に示すように、長さ方向を平行に揃えた状態で束ねられるが、方向を揃えて束ねられていれば必ずしもこの態様に限定されない。たとえば、図１５に示すように、すべての油捕集素材４の長さ方向の延長線の交点Ｐから放射状に方向を揃えて束ねてもよい。この場合、図１５に示すように、円錐台状の油捕集体２を作成することができる。また、すべての油捕集素材４の長さ方向の延長線の交点Ｐから放射状に方向を揃えて束ねて角錐台状の油捕集体２を作成してもよい。 In addition, as a general rule, the oil collecting material 4 is bundled in a state where the length directions are aligned in parallel as shown in FIG. 1, but is not necessarily limited to this mode as long as the directions are aligned. For example, as shown in FIG. 15, all the oil collecting materials 4 may be bundled in the same radial direction from the intersection P of the extension lines in the length direction. In this case, as shown in FIG. 15, a truncated cone-shaped oil collector 2 can be created. Alternatively, the pyramid-shaped oil collecting body 2 may be created by bundling the oil collecting materials 4 in the radial direction from the intersection point P of the extension lines in the length direction.
　また、油捕集体２は、通水性を確保することができれば、図１６（ａ）に示すように、らせん状の油捕集素材を用いて形成されていてもよく、図１６（ｂ）に示すように、ジグザグ状の油捕集素材を用いて形成されていてもよい。なお、通水性は、油捕集素材４を構成する樹脂フィルム同士の隙間、あるいは油捕集素材同士の隙間を水が流れることで確保される。この隙間は、油捕集体を濾材として使用する前には油捕集素材４同士の密着力により閉塞しているが、油捕集体に油水混合液を注入すると容易に開く。 Moreover, as long as water permeability can be ensured, the oil collector 2 may be formed using a spiral oil collecting material as shown in FIG. As shown, it may be formed using a zigzag oil collecting material. Water permeability is ensured by water flowing through the gaps between the resin films constituting the oil collection material 4 or between the oil collection materials. This gap is closed by the adhesion between the oil collecting materials 4 before using the oil collecting body as a filter medium, but easily opens when an oil / water mixture is injected into the oil collecting body.
　また、上述の実施の形態において、皺められた油捕集素材を一旦広げて再度皺め、油捕集素材を形成してもよい。このように、再度皺めて油捕集素材を形成した場合、油捕集素材の自己粘着性が低下するが油捕集率は向上する。 In the above-described embodiment, the oil collecting material that has been praised may be once spread and then praised again to form the oil collecting material. In this way, when the oil collecting material is formed by praising again, the self-adhesiveness of the oil collecting material is lowered, but the oil collecting rate is improved.
　また、上述の実施の形態において、油捕集素材に用いられる樹脂フィルムにたとえば凹凸状の加工や皺が予め施されていてもよい。この場合、樹脂フィルムの表面が複雑な形状となり、かつ表面積が広くなることからより油吸着性が向上することが期待できる。 Further, in the above-described embodiment, the resin film used for the oil collecting material may be provided with uneven processing or wrinkles in advance. In this case, since the surface of the resin film has a complicated shape and the surface area becomes large, it can be expected that the oil adsorbability is further improved.
　本発明によれば、油と水を含む液体から油のみを捕集して水を排出する高い油吸着性と通水性を備えた油捕集体を提供することができる。 According to the present invention, it is possible to provide an oil collector having high oil adsorbability and water permeability that collects only oil from a liquid containing oil and water and discharges the water.
