本発明は、通気性円筒状支持体に繊維状活性炭の原綿をポリエステル等の織布や不織布でサンドイッチ状に挟んでなる繊維状活性炭シートを巻着積層した吸着エレメントに関し、特に、水蒸気等で脱着再生する溶剤回収装置に好適な吸着エレメントに関するものである。
【０００２】
【従来の技術】
溶剤回収用の吸着材として，活性炭が古くから使用されているが，近年は繊維状活性炭を使用する事例が増えている。繊維状活性炭は，粉，粒状活性炭と比較して吸着容量の影響因子である比表面積が大きく，かつ吸着に関与するミクロ孔が吸着材表面に存在するため，吸脱着速度が速いという特長を備えている。また，繊維状活性炭は，フェルトや織物，さらには種々の形状に成形することが可能なため，吸着エレメントとして使用する場合にも応用範囲が広く，有機性ガス等の溶剤回収にも使用されている。
【０００３】
繊維状活性炭を使用した吸着エレメントの多くは，繊維状活性炭シートを通気性円筒状支持体の外周に巻着し，吸着時においては外側より被処理ガスを供給し，吸着層を通して円筒内孔部より処理ガスを取り出し，一方，脱着再生時には，円筒内孔部より吸着層へ加熱空気あるいは加熱蒸気を供給して，吸着物質を脱着し，回収する機構となっている。
しかしながら，このような構造の吸着エレメントは，繊維状活性炭巻着を支持体面で保持し難く，下方にずり落ちる傾向を示す。特に蒸気による脱着時においては，繊維状活性炭巻着層が蒸気の供給により多量の水分を含みやすいので，この傾向が顕著となる。
【０００４】
この繊維状活性炭巻着層のずり落ちを防止するために，実公昭６３−５７６６号公報には，通気性円筒状支持体として外周面に尖頭状突起を有するものを使用し，この通気性円筒状支持体の外周に繊維状活性炭シートを巻着し，その外周面を金属製の網状体で巻着した吸着エレメントが提案されている。
また，特開平８−１０５０６号公報には，上記の吸着エレメントの外周面に尖頭状突起を有する支持板を， 尖頭状突起が突き刺さるように配置した吸着エレメントが提案されている。
【０００５】
これらの吸着エレメントでは，繊維状活性炭巻着層のずり落ちが防止され，繊維状活性炭巻着層の密度が不均一性になるのが防止されるため，吸着エレメント全体を吸着材として有効に活用でき，吸着及び脱着能力を高めることができる。しかしながら，上記した吸着エレメントは，外周面に尖頭状突起物を有する通気性円筒状支持体に繊維状活性炭シートを巻着する際，尖頭状突起物によってシートが破損しするので作業性が悪い等の問題があった。
【０００６】
また，前者の吸着エレメントでは，繊維状活性炭を巻着した外周面に金属製の網状体を巻着して，ずれ落ち防止と繊維状活性炭の巻着密度の均一化を図っている。しかしながら，巻着層方向への密度は均一化できず，装置運転時の圧力損失が大きくなり，また，巻着密度が粗になる外側部で多少ずり落ちる傾向があり，吸着エレメント全体を有効に利用できないという問題があった。
【０００７】
【発明が解決しようとする課題】
本発明は，上記の問題を解決し，通気性円筒状支持体に繊維状活性炭シートを巻着積層した吸着エレメントにおいて，繊維状活性炭シートが均一に巻着され，水分を多量に吸収しても巻着層がずり落ちることがなく，吸着エレメント全体を有効に利用することができる吸着エレメントを提供することを技術的な課題とするものである。
【０００８】
【課題を解決するための手段】
発明者らは、上記の問題を解決するために鋭意検討した結果、本発明に到達した。
すなわち、本発明は、次の構成を有するものである。
（1）通気性円筒状支持体の外周に繊維状活性炭巻着層を有する吸着エレメントにおいて、繊維状活性炭の原綿をポリエステル等の織布や不織布でサンドイッチ状に挟んでなる繊維状活性炭シートとガラス繊維シートとを、ガラス繊維シートが外側になるように重ねて前記支持体に巻着してなり、
通気性円筒状支持体の外周面に螺旋状に金属線を固設するとともに、繊維状活性炭巻着層の外周面に、尖頭状突起を有する支持棒を突き刺さるように配設し、繊維状活性炭巻着層を内周面及び外周面の両方から支持したことを特徴とする吸着エレメント。
【０００９】
【発明の実施の形態】
以下、本発明を図面に基づいて説明する。
図1は、本発明の吸着エレメントの実施態様を示す一部断面説明図である。図1のエレメントは、通気性円筒状支持体１の外周に、繊維状活性炭の原綿をポリエステル等の織布や不織布でサンドイッチ状に挟んでなる繊維状活性炭シート２とガラス繊維シート３とを、ガラス繊維シート３が外側になるように重ねた状態で多層に巻着してガラス繊維が最外層に位置する繊維状活性炭層４を形成するとともに、繊維状活性炭巻着層４を複数本のリング状固定具５で固定し、巻着層4の一方の端面に有孔フランジ6を、他方の端面に無孔フランジ7を配設した構造を有するものである。
【００１０】
図１で示した吸着エレメントは，通気性円筒状支持体１の外周に，繊維状活性炭シート２とガラス繊維シート３とを， ガラス繊維シート３が外側になるように重ねた状態で多層に巻着して繊維状活性炭巻着層４を形成したので，単に繊維状活性炭シート２のみを多層に巻着する場合に比較して，ガラス繊維シート３の補強効果で巻密度を格段に高く， かつ均一に巻着することができる。そして，繊維状活性炭の巻密度は， ６０ｋｇ／ｍ３ 以上， 特に７０ｋｇ／ｍ３ 以上が好ましい。
このように，繊維状活性炭巻着層４における繊維状活性炭の巻密度が高いので水分を多量に吸収しても巻着層がずり落ちることがなく，このため，水蒸気等で脱着再生する溶剤回収装置用として好適な吸着エレメントである。
【００１１】
また、図１の吸着エレメントは、通気性円筒状支持体１として、外周面に金属線８を螺旋状に固設したものを使用し、尖頭状突起を有する支持棒９の複数本を繊維状活性炭巻着層４の外周面に円周方向と直交する方向で突き刺さるように配設し、複数本のリング状固定具５で固定したものである。
【００１２】
したがって、図１の吸着エレメントは、通気性円筒状支持体１の外周に、繊維状活性炭の原綿をポリエステル等の織布や不織布でサンドイッチ状に挟んでなる繊維状活性炭シート２とガラス繊維シート３とを、ガラス繊維シート３が外側になるように重ねた状態で多層に巻着して繊維状活性炭巻着層４を形成したのに加えて、金属線８と支持棒９で繊維状活性炭巻着層４を、その内周面側と外周面側から挟持するので、繊維状活性炭巻着層４のずり落ち防止効果が一層向上したものである。
【００１３】
本発明において，繊維状活性炭巻着層４を構成する繊維状活性炭シートの素材は特に限定されるものではなく，石炭ピッチ系，石油ピッチ系，セルロース系，フェノール樹脂系，ポリアクリロニトリル系，ビニロン系等のものを使用することができる。
繊維状活性炭の比表面積は大きいほど高い吸着性能が得られるが，実用的には ５００〜２０００ｍ２／ｇのものが好ましく，細孔直径は３０Å以下，細孔容積は０．２０〜１．３０ｃｍ３／ｇ のものが好ましい。
【００１４】
また、繊維状活性炭巻着層を構成する繊維状活性炭繊維シートは、繊維状活性炭の原綿をポリエステル繊維等の織布や不織布でサンドイッチ状に挟んだものを用いる。繊維状活性炭繊維シートの目付は１５０〜５００ｇ／ｍ２、特に２００〜３００ｇ／ｍ２が好ましく、目付が小さいと繊維状活性炭巻着層４における繊維状活性炭量が少なくて吸着性能が低下し、目付が大きいと巻着し難くなる傾向を示す。
【００１５】
繊維状活性炭繊維シートとともに繊維状活性炭巻着層を構成するガラス繊維シートは，ガラス繊維を不織布状に成形したものや織布にしたもの等を用いることができるが，強度のある織布が好ましい。ガラス繊維シートの目付は５〜３００ｇ／ｍ２， 特に２０〜１００ｇ／ｍ２ が好ましく，目付が小さいと補強材としての効果が少なく，目付が大きいと圧力損失が高くなる傾向を示す。
【００１６】
本発明において，通気性円筒状支持体としては，図１，２で示したような複数本の棒状体を円周方向に配してリング状体で棒状体の上下両端を固定したものや円筒状体に複数の孔を穿孔したもの等を使用することができる。
また，支持棒は，円柱状あるいは板状の本体に尖頭状突起を有することが，繊維状活性炭巻着層を支持するために好ましい。特に，円柱状のものは，吸着エレメントとの接触面積が最小に抑えられるため，吸着能力の低下を防止することができる。
さらに，リング状固定具としては，針金やバンド等を使用することができる。通気性円筒状支持体，支持棒，リング状固定具等の材質は，耐熱，耐食性の良好な金属，カーボン，合成樹脂等が使用でき，特にステンレスは耐熱性，耐食性及び機械的特性の点で有利である。
【００１７】
【実施例】
次に、本発明を実施例により具体的に説明する。
実施例１、比較例１
【００１８】
（実施例１の吸着エレメントの製造）
比表面積１５００ｍ２／ｇの石炭ピッチ系繊維状活性炭を、ポリエステル系不織布（ユニチカ社エルベス）でサンドイッチ状に挟みながらニードルパンチ加工し、繊維状活性炭９５重量％、目付２００ｇ／ｍ２の繊維状活性炭シートを製造した。
次に、上記で得られた繊維状活性炭シートを内側に、目付５５ｇ／ｍ２のガラスクロス（ユニチカグラスファイバー社製）を外側にして重ねた長さ４０ｃｍのシート状物を、外周面に螺旋状に金属線を固設した通気性円筒状支持体に何層にも巻着させ、巻着層最外面にガラスクロスが位置するようにして繊維状活性炭巻着層を形成した。
【００１９】
次いで、８本の支持棒を、その尖頭状突起物が繊維状活性炭巻着層内に突き刺すようにして繊維状活性炭層の外周面に円周方向と直交する方向に等間隔で取り付けた後、支持棒を針金で５カ所固定することにより繊維状活性炭巻着層を安定的に固定して実施例１の吸着エレメントを得た。この場合、通気性円筒状支持体、金属線、支持棒、針金等の材質はステンレスを採用した。
上記で得られた吸着エレメントは、繊維状活性炭巻着層が安定的に固定されており、繊維状活性炭の巻密度が７０ｋｇ／ｍ３の均一な巻着層を持つエレメントであった。
【００２０】
（吸着試験）
実施例１で得られた吸着エレメントをそれぞれ溶剤回収装置に設置し、吸着時間８分、水蒸気脱着時間５分、冷却時間３分で２０００ｐｐｍのジクロロメタンの吸脱着を繰り返した。
３０日後の繊維状活性炭巻着層のずり落ち量は、実施例１の吸着エレメントでは１ｍ高さ当たり５ｍｍであり、吸着量の低下は認められず、ジクロロメタンの除去率は９５％以上であった。
一方、ガラスクロス、支持棒を使用せず、また、円筒状支持体に螺旋状の金属線を配設せずに実施例１と同量の繊維状活性炭シートを巻着し、繊維状活性炭巻着層を５本の針金で固定した比較例１の吸着エレメントでは、１ｍ高さ当たり４０ｍｍ程度ずれ落ちており、１５日後から吸着率の低下が認められた。
【００２１】

The present invention relates to an adsorption element in which a fibrous activated carbon sheet obtained by sandwiching a fibrous activated carbon raw cotton in a sandwich shape with a woven fabric or nonwoven fabric of polyester or the like is wound and laminated on a breathable cylindrical support, and in particular, desorbed with water vapor or the like The present invention relates to an adsorption element suitable for a solvent recovery apparatus to be regenerated.
[0002]
[Prior art]
Activated carbon has been used for a long time as an adsorbent for solvent recovery, but in recent years, the use of fibrous activated carbon has increased. Compared with powder and granular activated carbon, fibrous activated carbon has a large specific surface area, which is an influencing factor of adsorption capacity, and has the features that the adsorption / desorption rate is fast because micropores related to adsorption exist on the surface of the adsorbent. ing. In addition, fibrous activated carbon can be formed into felts, woven fabrics, and various shapes, so it has a wide range of applications when used as an adsorbing element, and is also used for recovery of solvents such as organic gases. Yes.
[0003]
Many adsorption elements using fibrous activated carbon have a fibrous activated carbon sheet wrapped around the outer periphery of a breathable cylindrical support. During adsorption, the gas to be treated is supplied from the outside, and through the adsorption layer, a cylindrical inner hole is formed. The process gas is taken out, and on the other hand, at the time of desorption regeneration, heated air or heated steam is supplied from the cylindrical inner hole to the adsorption layer to desorb and recover the adsorbed material.
However, the adsorbing element having such a structure is difficult to hold the fibrous activated carbon wrapping on the support surface and tends to slide downward. This tendency is particularly noticeable at the time of desorption by steam because the fibrous activated carbon wrapping layer tends to contain a large amount of moisture by supplying steam.
[0004]
In order to prevent the fibrous activated carbon wrapping layer from slipping down, Japanese Utility Model Publication No. 63-5766 uses a breathable cylindrical support having a pointed projection on the outer peripheral surface. An adsorption element has been proposed in which a fibrous activated carbon sheet is wound around the outer periphery of a cylindrical support, and the outer peripheral surface thereof is wound with a metal mesh.
Japanese Patent Laid-Open No. 8-10506 proposes a suction element in which a support plate having a pointed protrusion is arranged on the outer peripheral surface of the above-described suction element so that the pointed protrusion pierces.
[0005]
In these adsorption elements, the fibrous activated carbon wrapping layer is prevented from slipping and the density of the fibrous activated carbon wrapping layer is prevented from becoming non-uniform, so the entire adsorption element is effectively used as an adsorbent. The adsorption and desorption ability can be increased. However, the adsorbing element described above has improved workability since the fibrous activated carbon sheet is wound around a breathable cylindrical support having a pointed protrusion on the outer peripheral surface, and the sheet is damaged by the pointed protrusion. There were problems such as bad.
[0006]
In the former adsorption element, a metallic net is wound around the outer peripheral surface around which the fibrous activated carbon is wound to prevent slippage and to make the winding density of the fibrous activated carbon uniform. However, the density in the direction of the wound layer cannot be made uniform, the pressure loss during operation of the device increases, and there is a tendency to slip slightly at the outer part where the winding density becomes coarse, making effective use of the entire adsorption element There was a problem that I could not.
[0007]
[Problems to be solved by the invention]
The present invention solves the above problems, and in an adsorption element in which a fibrous activated carbon sheet is wound and laminated on a breathable cylindrical support, even if the fibrous activated carbon sheet is uniformly wound and absorbs a large amount of moisture. It is a technical problem to provide an adsorption element that can effectively use the entire adsorption element without causing the winding layer to slide down.
[0008]
[Means for Solving the Problems]
The inventors have arrived at the present invention as a result of intensive studies to solve the above problems.
That is, the present invention has the following configuration.
(1) Fibrous activated carbon sheet and glass comprising a fibrous activated carbon wrapping layer on the outer periphery of a breathable cylindrical support, in which the raw fiber of the fibrous activated carbon is sandwiched between woven or nonwoven fabrics such as polyester A fiber sheet is wound around the support so that the glass fiber sheet is on the outside,
A metal wire is helically fixed on the outer peripheral surface of the breathable cylindrical support, and a support rod having a pointed protrusion is disposed on the outer peripheral surface of the fibrous activated carbon winding layer so as to pierce the fiber. An adsorption element characterized in that an activated carbon winding layer is supported from both an inner peripheral surface and an outer peripheral surface.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described below with reference to the drawings.
FIG. 1 is a partial cross-sectional explanatory view showing an embodiment of the adsorption element of the present invention. The element shown in FIG. 1 includes a fibrous activated carbon sheet 2 and a glass fiber sheet 3 formed by sandwiching a fibrous activated carbon raw cotton in a woven or nonwoven fabric such as polyester on the outer periphery of a breathable cylindrical support 1. The glass fiber sheet 3 is wound in multiple layers so as to be on the outer side to form a fibrous activated carbon layer 4 in which the glass fibers are positioned in the outermost layer, and the fibrous activated carbon wound layer 4 is formed of a plurality of rings. It has a structure in which a perforated flange 6 is disposed on one end face of the wound layer 4 and a non-perforated flange 7 is disposed on the other end face.
[0010]
The adsorbing element shown in FIG. 1 is wound in multiple layers in a state where a fibrous activated carbon sheet 2 and a glass fiber sheet 3 are stacked on the outer periphery of a breathable cylindrical support 1 so that the glass fiber sheet 3 is on the outside. Since the fibrous activated carbon wrapping layer 4 is formed by coating, the winding density is remarkably high due to the reinforcing effect of the glass fiber sheet 3 as compared with the case where only the fibrous activated carbon sheet 2 is wound in multiple layers. It can be wound evenly. The winding density of the fibrous activated carbon is preferably 60 kg / m 3 or more, particularly preferably 70 kg / m 3 or more.
Thus, since the winding density of the fibrous activated carbon in the fibrous activated carbon winding layer 4 is high, the winding layer does not slide down even if a large amount of moisture is absorbed. Adsorption element suitable for use.
[0011]
In addition, the adsorbing element in FIG. 1 uses a breathable cylindrical support 1 in which a metal wire 8 is spirally fixed on the outer peripheral surface, and a plurality of support rods 9 having pointed protrusions are made of fibers. It is arranged so as to be pierced in the direction orthogonal to the circumferential direction on the outer peripheral surface of the cylindrical activated carbon winding layer 4 and fixed by a plurality of ring-shaped fixing tools 5.
[0012]
Therefore, the adsorbing element of FIG. 1 includes a fibrous activated carbon sheet 2 and a glass fiber sheet 3 in which a raw fiber of activated carbon is sandwiched between a woven fabric and a nonwoven fabric of polyester or the like on the outer periphery of a breathable cylindrical support 1. Are wound in multiple layers with the glass fiber sheet 3 facing outside to form the fibrous activated carbon wound layer 4, and the fibrous activated carbon wound with the metal wire 8 and the support rod 9. Since the adhesion layer 4 is clamped from the inner peripheral surface side and the outer peripheral surface side, the slipping prevention effect of the fibrous activated carbon winding layer 4 is further improved.
[0013]
In this invention, the raw material of the fibrous activated carbon sheet which comprises the fibrous activated carbon winding layer 4 is not specifically limited, Coal pitch type | system | group, petroleum pitch type | system | group, a cellulose type, a phenol resin type | system | group, a polyacrylonitrile type | system | group, a vinylon type | system | group Etc. can be used.
The higher the specific surface area of the fibrous activated carbon, the higher the adsorption performance can be obtained. However, practically, it is preferably 500 to 2000 m 2 / g, the pore diameter is 30 mm or less, and the pore volume is 0.20 to 1.30 cm. Those of 3 / g are preferred.
[0014]
Further, as the fibrous activated carbon fiber sheet constituting the fibrous activated carbon wound layer, a fibrous activated carbon raw cotton sandwiched between woven fabrics and nonwoven fabrics such as polyester fibers is used. The basis weight of the fibrous activated carbon fiber sheet is preferably 150 to 500 g / m 2, and particularly preferably 200 to 300 g / m 2. If the basis weight is small, the amount of fibrous activated carbon in the fibrous activated carbon winding layer 4 is small and the adsorption performance is lowered, and the basis weight is reduced. Larger tend to be difficult to wind.
[0015]
The glass fiber sheet constituting the fibrous activated carbon wrapping layer together with the fibrous activated carbon fiber sheet can be a glass fiber molded into a nonwoven fabric or a woven fabric, but a strong woven fabric is preferred. . The basis weight of the glass fiber sheet is preferably 5 to 300 g / m 2 , particularly preferably 20 to 100 g / m 2. When the basis weight is small, the effect as a reinforcing material is small, and when the basis weight is large, the pressure loss tends to increase.
[0016]
In the present invention, as the air-permeable cylindrical support, a plurality of rod-shaped bodies as shown in FIGS. 1 and 2 are arranged in the circumferential direction, and a cylindrical body in which the upper and lower ends of the rod-shaped body are fixed is used. A material having a plurality of holes perforated in the shape can be used.
Further, it is preferable that the support rod has a pointed projection on a columnar or plate-like main body in order to support the fibrous activated carbon winding layer. In particular, the cylindrical shape can prevent the adsorption capacity from being lowered because the contact area with the adsorption element is minimized.
Furthermore, a wire, a band, etc. can be used as a ring-shaped fixing tool. Metal, carbon, synthetic resin, etc. with good heat resistance and corrosion resistance can be used as the material for the air-permeable cylindrical support, support rod, ring-shaped fixture, etc., especially stainless steel in terms of heat resistance, corrosion resistance and mechanical properties. It is advantageous.
[0017]
【Example】
Next, the present invention will be specifically described with reference to examples.
Example 1 and Comparative Example 1
[0018]
(Manufacture of the adsorption element of Example 1 )
A carbon fiber pitch activated carbon with a specific surface area of 1500 m 2 / g is needle-punched while sandwiched between polyester nonwoven fabrics (Elves of Unitika), and a fibrous activated carbon with 95% by weight of fibrous activated carbon and a basis weight of 200 g / m 2 . A sheet was produced.
Next, a sheet-like material having a length of 40 cm, which is obtained by stacking the fibrous activated carbon sheet obtained above with the glass cloth (manufactured by Unitika Glass Fiber Co., Ltd.) having a basis weight of 55 g / m 2 on the outside, spirals on the outer peripheral surface. A fibrous activated carbon winding layer was formed by winding a number of layers on a gas-permeable cylindrical support having a metal wire fixed in a shape so that the glass cloth was positioned on the outermost surface of the winding layer.
[0019]
Next, after attaching the eight support rods at equal intervals in the direction orthogonal to the circumferential direction on the outer peripheral surface of the fibrous activated carbon layer so that the pointed projections pierce into the fibrous activated carbon winding layer The adsorbing element of Example 1 was obtained by stably fixing the fibrous activated carbon winding layer by fixing the support rod at five points with a wire. In this case, stainless steel was used as the material for the breathable cylindrical support, the metal wire, the support rod, the wire, and the like.
The adsorbing element obtained above was an element having a uniform wound layer in which the fibrous activated carbon wound layer was stably fixed and the wound density of the fibrous activated carbon was 70 kg / m 3 .
[0020]
(Adsorption test)
Each of the adsorption elements obtained in Example 1 was installed in a solvent recovery apparatus, and adsorption and desorption of 2000 ppm of dichloromethane was repeated with an adsorption time of 8 minutes, a water vapor desorption time of 5 minutes, and a cooling time of 3 minutes.
The amount of slip of the fibrous activated carbon wrapping layer after 30 days was 5 mm per 1 m height in the adsorption element of Example 1, no decrease in the adsorption amount was observed, and the dichloromethane removal rate was 95% or more. .
On the other hand, the same amount of fibrous activated carbon sheet as that of Example 1 was wound without using a glass cloth and a support rod, and without providing a spiral metal wire on the cylindrical support, In the adsorption element of Comparative Example 1 in which the deposition layer was fixed with five wires, the displacement was about 40 mm per 1 m height, and a decrease in the adsorption rate was observed after 15 days.
[0021]
【The invention's effect】
In the adsorption element of the present invention, since the fibrous activated carbon is stably and uniformly held, the fibrous activated carbon winding layer does not slide down, and in particular, during the adsorption / desorption treatment in which desorption is performed using water vapor. It is possible to secure a stable adsorption rate.
