Description
【０００１】[0001]
本考案は、各種のフィルターとして用いられる補強された繊維状活性炭フィル ター材に関する。 The present invention relates to a reinforced fibrous activated carbon filter material used as various filters.
【０００２】[0002]
フェルト加工品を得る場合、従来一般に、各種の合成繊維や天然繊維などを反 毛式カード機およびニードルパンチ機によって処理し、必要な引張強度を備えた 各種フェルトを作成している。 In order to obtain a felt processed product, conventionally, various synthetic fibers and natural fibers are generally processed by a fluffing card machine and a needle punch machine to produce various felts having a required tensile strength.
【０００３】 ところが、例えば、繊維状活性炭の場合は、その原料繊維の伸度が 5％未満で あるといったように、繊維状活性炭における原料繊維の伸度が小さく、前述の従 来方法と同じようにしてフェルト加工を行っても、その製造されたフェルトにお いて引張強度が不足し、二次加工などによる実用化が困難であった。 そこで、従来では、ポリエステルやアラミド系繊維のように、 5〜15％の伸度 を有する繊維を補強用として混合してフェルト加工品を作成していた。However, for example, in the case of fibrous activated carbon, the elongation of the raw material fiber is less than 5%, and the elongation of the raw material fiber in the fibrous activated carbon is small, which is similar to the above-mentioned conventional method. However, even if the felt processing is performed, the produced felt has insufficient tensile strength, and it is difficult to put it into practical use by secondary processing. Therefore, conventionally, fibers such as polyester and aramid fibers having an elongation of 5 to 15% are mixed for reinforcement to prepare a felt processed product.
【０００４】[0004]
しかしながら、所定の引張強度を備えさせるためには、得られるフェルト加工 品の総重量の20％以上、補強用の繊維を混合する必要がある。そのため、繊維状 活性炭の含有重量が80％未満になってしまい、補強に起因して繊維状活性炭の含 有重量が減少するとともに、得られたフェルト加工品において、外表面に占める 繊維状活性炭の割合も減少し、繊維状活性炭が持っている本来の機能性が低下す る問題があった。 However, in order to provide a predetermined tensile strength, it is necessary to mix reinforcing fibers in an amount of 20% or more of the total weight of the obtained felt processed product. Therefore, the content of the fibrous activated carbon is less than 80%, the content of the fibrous activated carbon is reduced due to the reinforcement, and the fibrous activated carbon in the obtained felt processed product occupies the outer surface. The ratio also decreased, and the original functionality of the fibrous activated carbon deteriorated.
【０００５】 また、上述問題を解消するものとして、実開昭５４−１３９７８２号公報に、 有機質繊維層と繊維状活性炭による活性炭素繊維層とをニードルパンチによって 結合した活性炭素繊維構造体が開示されているが、有機質繊維層で補強するため には、所定の厚みの有機質繊維層を必要とし、それらの活性炭素繊維構造体を通 気する場合に、補強のための有機質繊維層自体での圧力損失が大きく、フィルタ ーとして使用するときに、繊維状活性炭の吸着能力を十分活かすことができない 欠点があった。As a solution to the above-mentioned problems, Japanese Utility Model Publication No. 54-139782 discloses an activated carbon fiber structure in which an organic fiber layer and an activated carbon fiber layer made of fibrous activated carbon are bonded by needle punching. However, in order to reinforce with an organic fiber layer, an organic fiber layer with a specified thickness is required, and when those activated carbon fiber structures are ventilated, the pressure of the organic fiber layer itself for reinforcement is required. The loss is large, and when used as a filter, it has the drawback that the adsorption capacity of fibrous activated carbon cannot be fully utilized.
【０００６】 本考案は、このような事情に鑑みてなされたものであって、繊維状活性炭の機 能性を低下させないようにするとともに圧力損失を減少させずに、また、再生処 理を水蒸気雰囲気下で行うような場所にも好適に使用できながら、良好に補強さ れた補強された繊維状活性炭フィルター材を提供できるようにすることを目的と する。[0006] The present invention has been made in view of the above circumstances, and prevents the function of the fibrous activated carbon from being lowered and the pressure loss to be reduced, and the regeneration process is performed by steam. It is an object of the present invention to provide a reinforced fibrous activated carbon filter material that is well reinforced while being suitable for use in a place where it is performed in an atmosphere.
【０００７】[0007]
本考案の補強された繊維状活性炭フィルター材は、このような目的を達成する ために、開口率80％以上の網目を有する網の両側それぞれに通気性を有するよう に繊維状活性炭を配し、両繊維状活性炭の少なくとも一方の一部の繊維を、網の 網目を通して他方側の繊維状活性炭に絡み付かせてあることを特徴としている。 In order to achieve such an object, the reinforced fibrous activated carbon filter material of the present invention has fibrous activated carbon arranged on both sides of a mesh having a mesh with an opening ratio of 80% or more so as to have air permeability. It is characterized in that at least one part of the fibers of both fibrous activated carbons is entwined with the fibrous activated carbon on the other side through the mesh of the mesh.
【０００８】 網としては、ポリエステル、アクリル、ポリプロピレンなどのプラスチック製 のネット状成形品や、金網のような金属製のネット状成形品、炭素繊維製のネッ ト状成形品、更には、ガラス繊維製のネット状成形品などが使用でき、プラスチ ック製のネット状成形品の場合であれば、得られるフェルト加工品を使用する雰 囲気に適した材質を選択して使用することにより、腐蝕損傷を防止できる利点が あり、一方、金属製のネット状成形品の場合であれば、強度を要求される箇所と か高温雰囲気下において、耐久性高く好適に使用できる利点があり、また、炭素 繊維製のネット状成形品は強度が高く、耐熱性および耐薬品性が有る。また、ガ ラス繊維製のネット状成形品の場合であれば、腐食損傷も無く、かつ、水蒸気雰 囲気下でも縮み変形を生じること無く良好に使用できる利点がある。As the net, a net-shaped molded product made of plastic such as polyester, acrylic and polypropylene, a net-shaped molded product made of metal such as a wire net, a net-shaped molded product made of carbon fiber, and further a glass fiber In the case of plastic net-shaped molded products, it is possible to use corrosion-resistant products by selecting a material suitable for the atmosphere in which the felt processed product is used. On the other hand, there is an advantage that it can prevent damage, on the other hand, in the case of a net-shaped molded product made of metal, it has the advantage that it can be suitably used with high durability in a place where strength is required or in a high temperature atmosphere. The fiber net-shaped molded product has high strength, heat resistance and chemical resistance. Further, in the case of a net-shaped molded product made of glass fiber, there is an advantage that it can be favorably used without corrosion damage and without shrinkage deformation even in a steam atmosphere.
【０００９】 繊維状活性炭としては、ピッチ系やポリアクリロニトリル（ＰＡＮ）系、セル ロース系などの各種の繊維状活性炭が使用できる。As the fibrous activated carbon, various fibrous activated carbons such as pitch-based, polyacrylonitrile (PAN) -based and cellulose-based can be used.
【００１０】[0010]
本考案によれば、網を、両側から繊維状活性炭によって挟み、一方側の繊維状 活性炭の繊維の一部を、あるいは、両側の繊維状活性炭それぞれの繊維の一部を ニードルパンチ機などにより網目を通して他方側に移動させ、他方側の繊維に絡 ませ、網を介して繊維状活性炭を補強保持する。 According to the present invention, the mesh is sandwiched between the fibrous activated carbons from both sides, and a part of the fibers of the fibrous activated carbon on one side or a part of the fibers of each of the fibrous activated carbons on both sides is meshed with a needle punch machine or the like. To move to the other side through the fiber, and to entangle the fiber on the other side and reinforce and hold the fibrous activated carbon through the net.
【００１１】 この補強された繊維状活性炭フィルター材でフィルターを構成することにより 、塗装工場等の排気ガス中に含まれる有機溶剤ガスや空気中の悪臭成分などを良 好に吸着することができる。By constructing a filter with the reinforced fibrous activated carbon filter material, it is possible to favorably adsorb the organic solvent gas contained in the exhaust gas of a coating plant or the like and the malodorous component in the air.

【００２４】 比較例１ 目付け量 300g ／m2のピッチ系繊維状活性炭 100％を用いてフェルト加工品を 作成した。Comparative Example 1 A felt processed product was prepared by using 100% of pitch-based fibrous activated carbon having a basis weight of 300 g / m 2 .
【００２５】 比較例２ 先に従来例で例示したポリエステル繊維を20％混合した目付け量 300g ／m2の ものを用いてフェルト加工品を作成した。Comparative Example 2 A felt-processed product was prepared by using 20% of the polyester fiber exemplified in the conventional example and having a basis weight of 300 g / m 2 .
【００２６】 上記実施例１（表中の）、比較例１（表中の）および比較例２（表中の ）それぞれのフェルト加工品を用い、引張強度およびトルエン吸着能それぞれに ついて比較実験したところ、表に示す結果を得た。Using the felt processed products of Example 1 (in the table), Comparative Example 1 (in the table) and Comparative Example 2 (in the table), comparative experiments were carried out on tensile strength and toluene adsorption capacity. However, the results shown in the table were obtained.
【００２７】 引張強度は、JIS Ｌ１０９６に準拠して試料サイズ50mm×100 mmで測定した。 トルエン吸着能（g ／g ）は、溶剤蒸気吸着性能試験装置を用い、JIS Ｋ１４ ７４に準拠して測定した。The tensile strength was measured according to JIS L1096 with a sample size of 50 mm × 100 mm.

【００２８】[0028]
【表１】 [Table 1]
【００２９】 上記結果から、本考案の実施例１のフェルト加工品Ａによれば、比較例１およ び比較例２それぞれのフェルト加工品に比べ、引張強度およびトルエン吸着能の いずれにおいても優れ、しかも、フェルト加工をしない繊維状活性炭と同じトル エン吸着能が得られており、本来の機能性のひとつである溶剤吸着性能を全く低 下せずに引張強度を向上できることが明らかであった。From the above results, according to the felt processed product A of Example 1 of the present invention, both the tensile strength and the toluene adsorption capacity are superior to the felt processed products of Comparative Example 1 and Comparative Example 2. In addition, the same toluene adsorption capacity as the fibrous activated carbon without felt processing was obtained, and it was clear that the tensile strength could be improved without degrading the solvent adsorption performance, which is one of the original functions. .
【００３０】 実施例２ 前述実施例１のポリプロピレン製の網に代えて、厚みが 0.2mmで、空間率が95 ％のガラス繊維製ネット状成形品（倉敷紡績株式会社製クレネット、型番Ｇ３３ ８０、試料サイズ 100mm×100 mmで、JIS Ｌ１０９６に準拠して測定した公称引 張強度が縦方向75kg、横方向72kg）を用いた。Example 2 In place of the polypropylene net of Example 1 described above, a glass fiber net-shaped molded product having a thickness of 0.2 mm and a porosity of 95% (Kurashiki Spinning Co., Ltd., Clenet, Model No. G33 80) A sample size of 100 mm × 100 mm was used, and the nominal tensile strength measured according to JIS L1096 was 75 kg in the longitudinal direction and 72 kg in the lateral direction.
【００３１】 前述実施例１および実施例２のフェルト加工品それぞれを、試料サイズ 100mm ×100mm にして乾燥炉内に入れ、温度 120℃の高温雰囲気下で 1時間加熱保持し てサイズの変化を求めたところ、実施例２のフェルト加工品では縮み変形が見ら れなかったが、実施例１のフェルト加工品では、縦方向で 7％、横方向で 3％の 縮みが見られた。Each of the felt-processed products of Examples 1 and 2 described above was placed in a drying furnace with a sample size of 100 mm × 100 mm, and heated and held for 1 hour under a high temperature atmosphere of 120 ° C. to obtain a size change. As a result, the felt-processed product of Example 2 did not show shrinkage deformation, but the felt-processed product of Example 1 showed shrinkage of 7% in the longitudinal direction and 3% in the transverse direction.
【００３２】 この結果から、網をガラス繊維製のネット状成形品で形成することにより、耐 熱性に優れた補強された繊維状活性炭フィルター材を得られることが明らかであ る。From these results, it is clear that a reinforced fibrous activated carbon filter material having excellent heat resistance can be obtained by forming the net from a glass fiber net-shaped molded product.
【００３３】 実施例３ 網１の片面側に、比表面積が 700m2/gのピッチ系繊維状活性炭不織布２ａを配 してニードリングを施した後、他方側に、比表面積が1500m2/gのピッチ系繊維状 活性炭不織布２ｂを、前記のものの 2/3の重量分だけ配し、ニードリングを施し てフェルト加工品Ａを作成した。Example 3 A pitch-based fibrous activated carbon nonwoven fabric 2a having a specific surface area of 700 m 2 / g was placed on one side of the mesh 1 and subjected to needling, and then the other side had a specific surface area of 1500 m 2 / g. The pitch-based fibrous activated carbon non-woven fabric 2b of No. 2 was placed in an amount of 2/3 of the weight described above, and the product was felted to obtain a felt processed product A.
【００３４】 この実施例３のフェルト加工品によれば、全体としての比表面積は約1000m2/g でありながら、一方側のピッチ系繊維状活性炭不織布２ａにおける細孔半径は小 さくて吸着力を大きくでき、低濃度の溶剤ガスをも良好に吸着でき、それに対し て他方側のピッチ系繊維状活性炭不織布２ｂにおける細孔半径は大きくて吸着量 を大にでき、高濃度の溶剤ガスを多量に吸着でき、吸着しようとする溶剤ガスの 濃度のいかんにかかわらず、溶剤ガスを良好に吸着できる利点を有している。According to the felt processed product of Example 3, the specific surface area as a whole is about 1000 m 2 / g, but the pore radius in the pitch-based fibrous activated carbon nonwoven fabric 2a on one side is small and the adsorption force is small. The pitch radius of the pitch-based fibrous activated carbon nonwoven fabric 2b on the other side is large and the adsorption amount can be increased, and a large amount of high concentration solvent gas can be adsorbed. It has the advantage of being able to adsorb the solvent gas satisfactorily regardless of the concentration of the solvent gas to be adsorbed.
【００３５】 実施例３のフェルト加工品を用い、天然ガス（都市ガス）中の付臭成分である ジメチルサルファイドを濃度2ppmで流し、その破過吸着量を測定したところ、 9 .1mg/gであり、例えば、細孔半径の小さい比表面積が 700m2/gのピッチ系繊維状 活性炭不織布の場合には破過吸着量が 7.5mg/gであるのに対し、それよりも比表 面積が大きいにもかかわらず破過吸着量を増大でき、全体として良好な吸着性能 を得られることが明らかであった。Using the felt processed product of Example 3, dimethyl sulfide, which is an odorizing component in natural gas (city gas), was caused to flow at a concentration of 2 ppm, and the breakthrough adsorption amount was measured to be 9.1 mg / g. Yes, for example, in the case of a pitch-based fibrous activated carbon nonwoven fabric with a small pore radius and a specific surface area of 700 m 2 / g, the breakthrough adsorption amount is 7.5 mg / g, whereas the specific surface area is larger than that. Nevertheless, it was clear that the amount of breakthrough adsorption could be increased and good adsorption performance could be obtained as a whole.
【００３６】 実施例３においては、吸着しようとする溶剤ガスの性状に応じて、網１の一方 側のピッチ系繊維状活性炭不織布２ａと他方側のピッチ系繊維状活性炭不織布２ ｂとの比表面積を互いに異ならせるようにすれば良く、また、得ようとする全体 としての比表面積に応じて、両者の重量比を調整すれば良い。In Example 3, the specific surface area of the pitch-based fibrous activated carbon nonwoven fabric 2a on one side of the net 1 and the pitch-based fibrous activated carbon nonwoven fabric 2b on the other side of the net 1 is changed according to the properties of the solvent gas to be adsorbed. May be different from each other, and the weight ratio of the two may be adjusted according to the overall specific surface area to be obtained.
【００３７】 この実施例３に使用する網１としては、プラスチック製、金属製、炭素繊維製 、ガラス繊維製いずれのネット状成形品であっても良い。The net 1 used in Example 3 may be a net-shaped molded product made of plastic, metal, carbon fiber, or glass fiber.

【００４０】 鋼板またはステンレス鋼板により形成した下側凸状部材１３の凸部１３ａの上 面と、鋼板またはステンレス鋼板により形成した上側凸状部材１４の凸部１４ａ の下部とにわたり、筒状に形成した金網１５が溶接によって連接され、両凸部１ ３ａ，１４ａおよび金網１５それぞれの外周面全面を被覆するように、前記フェ ルト加工品Ａが巻き付けられ、溶剤回収のための加熱水蒸気の供給に起因して網 １が縮み変形し、フェルト加工品Ａの上下幅が短くなってフェルト加工品Ａと下 側凸状部材１３および上側凸状部材１４それぞれの平板部分との間に隙間を生じ たとしても、その隙間から溶剤が洩れて吸着不良を生じることを両凸部１３ａ， １４ａによって防止できるように構成されている。A tubular shape is formed that extends from the upper surface of the convex portion 13a of the lower convex member 13 formed of a steel plate or a stainless steel plate to the lower portion of the convex portion 14a of the upper convex member 14 formed of a steel plate or a stainless steel plate. The wire mesh 15 is connected by welding, and the felt-processed product A is wound so as to cover the entire outer peripheral surfaces of both the convex portions 13a and 14a and the wire mesh 15, and to supply heated steam for solvent recovery. Due to this, the mesh 1 contracted and deformed, and the vertical width of the felt processed product A became shorter, and a gap was created between the felt processed product A and the flat plate portions of the lower convex member 13 and the upper convex member 14, respectively. Even in this case, the convex portions 13a and 14a can prevent the solvent from leaking from the gap and causing the adsorption failure.
【００４１】 また、フェルト加工品Ａの上下それぞれにおいて、針金１６により両凸部１３ ａ，１４ａに縛り付けられており、溶剤回収のために供給される加熱水蒸気をフ ェルト加工品Ａが吸収し、その重量増大に起因してフェルト加工品Ａがずれ落ち 、フェルト加工品Ａの上端と上側凸状部材１４との間に隙間を生じ、その隙間か ら溶剤が洩れて吸着不良を生じることをより良好に防止できるように構成されて いる。In addition, the upper and lower sides of the felt processed product A are bound by the wire 16 to the both convex portions 13a and 14a, and the felt processed product A absorbs the heated steam supplied for solvent recovery, The felt processed product A slips off due to the increase in the weight, and a gap is created between the upper end of the felt processed product A and the upper convex member 14, and the solvent leaks from the gap, resulting in poor adsorption. It is configured so that it can be effectively prevented.
【００４２】 下側凸状部材１３の凸部１３ａは、有底筒状体を逆向きにして構成され、加熱 水蒸気による処理に際し、水滴が溜まることを防止できるように構成されている 。The convex portion 13a of the lower convex member 13 is formed by reversing the bottomed tubular body so as to prevent water droplets from accumulating during the treatment with heated steam.
【００４３】 一方、上側凸状部材１４の凸部１４ａは、中空筒状体で構成され、フェルト加 工品Ａと金網１５と上側凸状部材１４の凸部１４ａ内空間とを通じて処理ガスや 水蒸気が流されるようになっている。On the other hand, the convex portion 14 a of the upper convex member 14 is composed of a hollow cylindrical body, and through the felt processing product A, the wire net 15 and the space inside the convex portion 14 a of the upper convex member 14, the processing gas and the water vapor. Is being washed away.
【００４４】 上記構成の吸着エレメントを水槽中に浸漬し、上側凸状部材１４に配管を介し てエアーポンプを連通接続し、吸着エレメント内にエアーを供給したところ、フ ェルト加工品Ａの全面から気泡が発生し、フェルト加工品Ａの上下端それぞれか らの洩れが無いものであった。The adsorption element having the above structure was immersed in a water tank, an air pump was connected to the upper convex member 14 through a pipe, and air was supplied into the adsorption element. Air bubbles were generated, and there was no leakage from the upper and lower ends of the felt processed product A, respectively.
【００４５】 また、水中より取り出して、24時間静置したが、フェルト加工品Ａのずれ落ち は生じなかった。 更に、上記吸着エレメントを溶剤吸着装置に組み込み、濃度が2000ppm のフロ ンガス含有ガスをブロアーによって 3m3/min供給したが、出口側においてフロン ガスは検知されず、フェルト加工品Ａによって良好に吸着されていることが明ら かであった。Further, the felt processed product A was taken out from water and allowed to stand still for 24 hours, but the felt processed product A did not slip off. Furthermore, the adsorption element was incorporated into a solvent adsorption device, and a gas containing 2,000 ppm of fluon gas was supplied by a blower at 3 m 3 / min. It was clear that

以上の説明から明らかなように、本考案によれば、繊維状活性炭で網を挟み、 その網目を利用して繊維状活性炭を補強保持するから、得られたフェルト加工品 の外表面のすべてに繊維状活性炭を露出させることができ、補強構成に影響され ること無く、繊維状活性炭が本来的に持っている機能を 100％発揮させることが 可能になった。 As is clear from the above description, according to the present invention, the mesh is sandwiched between the fibrous activated carbons, and the fibrous activated carbons are reinforced and held by utilizing the meshes, so that the entire outer surface of the obtained felt processed product is retained. Since the fibrous activated carbon can be exposed, it has become possible to exert 100% of the original function of the fibrous activated carbon without being affected by the reinforcing structure.
【００４７】 また、繊維状活性炭は炭素繊維の表面に微細な孔を有しており、その強度が非 常に弱いため、丁寧に取り扱わないと、破れなどの損傷を生じやすいが、本考案 によると、その一部の繊維の絡み付きにより、網によって補強するから、得られ たフェルト加工品全体としての強度が高くて容易に取り扱うことができ、例えば 、溶剤吸着装置などに組み込むような場合でも、別途専用の保持具を使用せずに 済み、また、保持具を使用するにしても、その保持具の構成を簡単にできるとい ったように、各種用途に使用する場合において、付随する構成のコストダウンを 図ることができ、経済性を向上できるようになった。In addition, since the fibrous activated carbon has fine pores on the surface of the carbon fiber and its strength is extremely weak, damage such as tearing tends to occur unless it is handled carefully, but according to the present invention, Since some of the fibers are entangled and reinforced by a net, the strength of the obtained felt processed product as a whole is high and it can be easily handled. It is not necessary to use a dedicated holder, and even if the holder is used, the structure of the holder can be simplified. It is possible to achieve downtime and improve economic efficiency.
【００４８】 そのうえ、網に、開口率80％以上の網目を備えさせるから、溶剤吸着装置など に使用する場合において、その通気に伴う圧力損失を減少でき、繊維状活性炭の 吸着能力を十分発揮させることができるようになった。 また、網をガラス繊維で形成する場合には、溶剤吸着装置などに組み込み、加 熱水蒸気の雰囲気下に曝して、溶剤の回収と再生とを行うときに、金属製の網の ような腐食損傷を回避でき、また、プラスチック製の網のような縮み変形をも回 避でき、その吸着性能を長期にわたって良好に発揮でき、耐久性に優れた繊維状 活性炭を提供できる。In addition, since the mesh is provided with a mesh having an opening ratio of 80% or more, when used in a solvent adsorption device or the like, the pressure loss due to the ventilation can be reduced, and the adsorption ability of the fibrous activated carbon can be sufficiently exhibited. I was able to do it. In addition, when the net is made of glass fiber, it is installed in a solvent adsorption device and exposed to the atmosphere of heated steam to recover and regenerate the solvent. In addition, it is possible to avoid shrinkage deformation such as that of a plastic net, to exert its adsorption performance satisfactorily for a long time, and to provide fibrous activated carbon with excellent durability.
