Description
本発明は、例えば空気中に含まれる有機溶剤等の悪臭成分を吸着除去する排ガス処理装置等に使用される吸着素子に関するものである。 The present invention relates to an adsorption element used for an exhaust gas treatment apparatus or the like which adsorbs and removes an offensive odor component such as an organic solvent contained in air, for example.
従来、吸着素子としては、吸着材、有機繊維、有機バインダー、無機バインダー等を含む吸着シートをハニカム成形機により、ハニカム成形用接着剤を使用し、ハニカム状に成形した物が知られている（例えば特許文献１参照）。 Heretofore, as an adsorption element, there is known a honeycomb-shaped adhesive sheet containing an adsorption material, an organic fiber, an organic binder, an inorganic binder and the like, which is formed into a honeycomb shape using a honeycomb forming adhesive by a honeycomb forming machine See, for example, Patent Document 1).
この吸着素子には、ゼオライトが吸着材として含まれると、特許文献１に記載されている。ゼオライトの形状には粉末状、粒子状、もしくはペレット状の形状がある。吸着素子の柔軟性や機械的強度には、骨格素材である有機繊維などが役割を担う。吸着素子として高い性能を発揮するには吸着材の含有比率を向上させることが有効であるが、反対に骨格素材である有機繊維や無機繊維の含有比率が下がるため、結果的には吸着素子の柔軟性や強度は低下するという課題があった。
吸着材には特有の見かけ密度（ゆるめかさ密度やタップ密度）があり、それには吸着材の化学的な種類（活性炭、ゼオライト種、シリカゲルなど）と、バルクとしての形状（粒径、繊維径など）が密接に関与する。単純に吸着素子に含まれる吸着材の含有量が同じであっても、見かけ密度と粒径から計算される粒子の個数には違いがあり、粒子数が多すぎて骨格素材の絡まりが少なくなり、実用上の強度が得られないという課題があった。 The adsorbent has a specific apparent density (loose bulk density or tap density), which includes the chemical type of the adsorbent (activated carbon, zeolite, silica gel, etc.) and the shape as bulk (particle diameter, fiber diameter, etc.) ) Are closely involved. Even if the content of the adsorbent contained in the adsorption element is simply the same, there is a difference in the number of particles calculated from the apparent density and the particle diameter, the number of particles is too large, and the entanglement of the framework material decreases. There is a problem that practical strength can not be obtained.
本発明は上記課題に鑑みてなされたものであり、吸着素子として十分な柔軟性や強度と高い吸着材含有比率を両立した吸着素子を提供することを目的とする。 The present invention has been made in view of the above problems, and an object of the present invention is to provide an adsorptive element having both sufficient flexibility and strength as the adsorptive element and a high adsorbent content ratio.
本発明者らは上記課題を解決するため、鋭意研究した結果、遂に本発明を完成するに到った。すなわち、本発明は以下の通りである。 As a result of earnest studies to solve the above problems, the present inventors have finally completed the present invention. That is, the present invention is as follows.
この吸着素子によれば、吸着材（Ａｘ，：ｘ＝１，２，３・・・ｎ）を少なくとも１種類以上を含む、多数の空気通路を有する吸着シート（吸着素子前駆体）を用いたハニカム状構造の吸着素子であって、上記吸着材（Ａｘ）のタップ密度をＡｘａ、吸着材粒子を球状と仮定した時に吸着材粒子の平均粒径をから算出した球体積をＡｘｂ、上記吸着材が上記吸着シートに含まれる重量比率（％）をＡｘｃとすると、上記吸着シート１ｇあたりに含まれる平均粒子数Ａｘｄは以下の式１で表される。
According to this adsorption element, an adsorption sheet (adsorption element precursor) having a large number of air passages containing at least one or more types of adsorption materials (Ax ,: x = 1, 2, 3... N) is used It is an adsorption element of honeycomb structure, and assuming that tap density of the adsorbent (Ax) is Axa and adsorbent particles are spherical, spherical volume calculated from average particle diameter of adsorbent particles is Axb, and the adsorbent Assuming that the weight ratio (%) contained in the adsorbing sheet is Axc, the average particle number Axd contained in 1 g of the adsorbing sheet is represented by the following
上記吸着シート１ｇあたりに含まれる少なくとも１種類以上の上記吸着材（Ａｘ）の総平均粒子数は、以下の式２で表される。当該吸着素子の平面圧縮強度が３ｋＰａ以上である。 The total average particle number of at least one or more of the adsorbents (Ax) contained in 1 g of the adsorption sheet is represented by the following formula 2.

本発明に基づいた実施の形態の吸着素子について、以下、図面を参照しながら説明する。以下に説明する実施の形態において、個数、量などに言及する場合、特に記載がある場合を除き、本発明の範囲は必ずしもその個数、量などに限定されない。同一の部品、相当部品に対しては、同一の参照番号を付し、重複する説明は繰り返さない場合がある。実施の形態における構成を適宜組み合わせて用いることは当初から予定されていることである。 An adsorption element according to an embodiment based on the present invention will be described below with reference to the drawings. In the embodiments described below, when the number, the amount, and the like are mentioned, the scope of the present invention is not necessarily limited to the number, the amount, and the like unless otherwise specified. The same parts and corresponding parts are denoted by the same reference numerals, and duplicate descriptions may not be repeated. It is planned from the beginning to use appropriately combining the configurations in the embodiments.
［湿式製法による混合抄造（吸着材を内添して紙を作る）］
吸着材と有機繊維や無機繊維などの骨格素材とを混合抄造して吸着シートをハニカム成形機により、ハニカム成形用接着剤を使用し、ハニカム状に成形した吸着素子を得る場合、吸着材は骨格素材同士の絡み合い点を減らしてしまう。そのため、吸着材の嵩密度および粒径の観点からすると、単位重量当たりの体積を表す比容積が小さい方が吸着材の占有体積が小さくなり、骨格素材同士の絡み合い点を減らしにくいため好ましい。
[Mixed papermaking by wet process (adsorbent is internally added to make paper)]
When an adsorbent is mixed with a framework material such as organic fibers or inorganic fibers to form an adsorbent sheet by using a honeycomb forming adhesive with a honeycomb forming machine to obtain an adsorbent element formed into a honeycomb shape, the adsorbent is a framework It reduces the entanglement points between the materials. Therefore, from the viewpoint of the bulk density and particle diameter of the adsorbent, the smaller the specific volume representing the volume per unit weight is, the smaller the occupied volume of the adsorbent is, and the more difficult it is to reduce the entanglement points between the framework materials.
実際には、比容積の逆数である密度が大きい吸着材が好ましいことと同義である。吸着材の形状は粉末状、粒状、繊維状などがあり、吸着素子に含有される量を考えると、粉体１つ、粒子１つ、繊維１本ではなく多量の粉末、粒子、繊維が担持されるのが一般的である。そのため、粉末、粒子、繊維の集合体としての充填密度としてはゆるめかさ密度やタップ密度（かためかさ密度とも言う）があるが、吸着素子としてより吸着材を高含有重量比率にするためにも、より緻密に充填された状態を表すタップ密度が特に重要となる。 In practice, it is synonymous with the preference for adsorbents with high density, which is the reciprocal of the specific volume. The shape of the adsorbent is powdery, granular, fibrous, etc. Considering the amount contained in the adsorption element, one powder, one particle, one fiber, not a large amount of powder, particles, fibers are carried It is common to Therefore, there are loose bulk density and tap density (also referred to as bulk density) as packing density as an aggregate of powder, particles, and fibers, but it is also for increasing the content ratio of the adsorbent as the adsorption element. The tap density, which represents a more tightly packed state, is particularly important.
混合抄造が湿式抄紙の場合、吸着材は粉末や粒状が好ましく、粉末状が特に好ましい。粉末のタップ密度は０．１ｇ／ｃｍ３〜２．０ｇ／ｃｍ３が好ましく、さらに好ましくは０．２〜１．０ｇ／ｃｍ３の範囲であるとよい。 In the case of mixed papermaking in wet papermaking, the adsorbent is preferably powder or granular, and particularly preferably powdery. The tap density of the powder is preferably 0.1g / cm 3 ~2.0g / cm 3 , more preferably may be in the range of 0.2 to 1.0 g / cm 3.
［粒径との関係］
吸着材（Ａｘ）の粒径は、レーザー回折などで評価することができ、平均粒径０．００１μｍ〜３０．０μｍの範囲が好ましく、さらに好ましくは０．０１μｍ〜２０μｍである。吸着材の粒径は吸着材の種類に依存する場合があり、特にゼオライトは結晶種によって結晶サイズが異なりやすい。ゼオライトの結晶種によっては３μｍ以下の結晶サイズがあり、その場合は完全な分散状態を得ることが難しく、レーザー回折では実際の粒径より大きな粒径（二次粒子径）を見ている場合もある。その場合は、ＳＥＭ（走査電子顕微鏡:Scanning Electron Microscope）などの画像解析で確認された最小単位である結晶サイズの平均値を平均粒径とみなす。
[Relationship with particle size]
The particle size of the adsorbent (Ax) can be evaluated by laser diffraction or the like, and the average particle size is preferably in the range of 0.001 μm to 30.0 μm, and more preferably 0.01 μm to 20 μm. The particle size of the adsorbent may depend on the type of adsorbent, and in particular, the crystal size of the zeolite tends to differ depending on the crystal species. Depending on the crystal type of zeolite, there is a crystal size of 3 μm or less, in which case it is difficult to obtain a completely dispersed state, and even when the particle size (secondary particle size) larger than the actual particle size is observed in laser diffraction. is there. In that case, the average value of the crystal size which is the smallest unit confirmed by image analysis such as SEM (Scanning Electron Microscope) is regarded as the average particle diameter.
実施の形態における吸着材は、活性炭またはゼオライトである。活性炭およびゼオライトは、低濃度の有機化合物を吸着および脱着するのに優れている。 The adsorbent in the embodiment is activated carbon or zeolite. Activated carbon and zeolites are excellent for adsorbing and desorbing low concentrations of organic compounds.
活性炭の場合は、形態は、平均粒径が１０μｍ以上５０μｍ以下の粉末、または平均繊維径が１０μｍ以上３０μｍ以下の繊維が挙げられる。活性炭の原料は特に指定しないが、椰子柄、石炭、ピッチ、フェノール樹脂、ポリアクリロニトリル、セルロースなどがある。 In the case of activated carbon, the form may be a powder having an average particle diameter of 10 μm to 50 μm or a fiber having an average fiber diameter of 10 μm to 30 μm. The raw material of the activated carbon is not particularly specified, but may be coconut palm, coal, pitch, phenol resin, polyacrylonitrile, cellulose and the like.
実施の形態における吸着材は、好ましくはゼオライトが良い。ゼオライトは、耐熱温度が高く、活性炭よりも吸着時の有機溶剤などとの反応性が低いので、耐熱性に優れ、発熱の危険性が低い。またゼオライトは、活性炭よりもシャープな細孔構造を有するので、有機溶剤などの吸着性能が優れている。ゼオライトの場合は、形態は平均粒径が１μｍ以上２０μｍ以下の粉末である。ゼオライトは、天然に産出されるゼオライトもあるが、人工合成ゼオライトが適している。具体的には、ベータ型、ＺＳＭ−５型、フェリエライト型、モルデナイト型、Ｌ型、Ｙ型、Ａ型などがある。 The adsorbent in the embodiment is preferably zeolite. Zeolite has high heat resistance temperature and lower reactivity with organic solvents at the time of adsorption than activated carbon, so it is excellent in heat resistance and has a low risk of heat generation. In addition, since zeolite has a sharper pore structure than activated carbon, the adsorption performance of organic solvents and the like is excellent. In the case of zeolite, the form is a powder having an average particle size of 1 μm to 20 μm. Zeolites are also naturally produced zeolites, but artificially synthesized zeolites are suitable. Specifically, there are beta type, ZSM-5 type, ferrierite type, mordenite type, L type, Y type, A type and the like.
実施の形態における吸着材は、更に好ましくは、シリカ／アルミナ比の高いハイシリカゼオライトが好ましい。ハイシリカゼオライトは、被処理ガス中から有機溶剤などを吸着するにあたって、被処理ガス中の水分、湿度の影響を受けにくいためである。シリカ／アルミナ比は１５以上が良く、更には５０以上がより良い。 More preferably, the adsorbent in the embodiment is a high silica zeolite having a high silica / alumina ratio. High silica zeolite is less susceptible to the influence of moisture and humidity in the gas to be treated when adsorbing an organic solvent or the like from the gas to be treated. The silica / alumina ratio is preferably 15 or more, and more preferably 50 or more.
実施の形態における吸着素子は、吸着材を少なくとも１つ含む。前述の各種の活性炭およびゼオライトのうちの１つまたは複数を選択してもよい。複数の吸着材が選択される場合、その割合は特に限定されない。吸着材は、被処理ガスの処理条件に応じて、適宜選択されればよい。 The adsorbing element in the embodiment includes at least one adsorbing material. One or more of the various activated carbons and zeolites described above may be selected. When multiple adsorbents are selected, the ratio is not particularly limited. The adsorbent may be appropriately selected according to the treatment conditions of the gas to be treated.

先述したように、吸着材と有機繊維や無機繊維などの骨格素材とを混合抄造して吸着シートを得る場合、吸着材は骨格素材同士の絡み合い点を減らしてしまうため吸着シートの強度低下を招きやすい。そのため、実用的な強度を得るには一定量以下の粒子総数に抑えることが好ましく、吸着シート１ｇあたりに含まれる少なくとも１種類以上の吸着材Ａｘの総平均粒子数は、以下の［式２］で表され、８．０×１０１２以下であることが好ましい。 As described above, in the case of forming an adsorption sheet by mixing and forming an adsorbent and a framework material such as an organic fiber or an inorganic fiber, the adsorbent reduces the entanglement points of the framework materials and causes strength reduction of the adsorption sheet. Cheap. Therefore, in order to obtain practical strength, it is preferable to keep the total number of particles not more than a fixed amount, and the total average number of particles of at least one adsorbent Ax contained in 1 g of the adsorbent sheet is the following [Formula 2] And is preferably 8.0 × 10 12 or less.

More preferably, the number of cells is 50 to 70 cells / cm 2 . When the number of cells is less than 30 cells / cm 2 , the adsorption performance is lowered, and when it exceeds 70 pieces / cm 2 , it is necessary to reduce the thickness of the sheet constituting the partition wall of the honeycomb structure.

[Consideration of B-1 and B-2 in the manufacturing method]
The organic component (B) used in the production of the adsorption element of the present embodiment is a low temperature decomposable organic component which is thermally decomposed at 150 ° C. to 300 ° C. in addition to the heat resistant organic fiber (B-1) such as the aramid fiber It is desirable to use (B-2). The low temperature decomposable organic component (B-2) works as a binder for bonding the (A-1) component to the (B-1) component and the (B-1) component at the time of wet papermaking. The component (B-2) covers the adsorbent of the sheet-like material and the final adsorption element (the adsorption element of this embodiment) after the formation of the honeycomb-like material. It is also possible to make (B-2) a carbide or cause decomposition and disappearance to reduce the coating of the adsorbent of the final adsorption element (the adsorption element of the present embodiment).
上記シート状物及びハニカム状物で熱処理を行う場合、加熱オーブン等を用い空気雰囲気中で実施するのが好ましい。熱処理温度は耐熱性有機成分（Ｂ−１）の融点もしくは分解温度（Ｔ１℃）以下好ましくは５℃〜２０℃低く（Ｔ１−５〜Ｔ１−２０℃）、低温度分解成分（Ｂ−２）の分解温度（Ｔ２℃）以上、好ましくは分解温度の１００℃〜２００℃以上（Ｔ２＋１００〜Ｔ２＋２００℃）の温度で処理時間は１分〜６０分好ましくは１分〜３０分である。通常３５０℃〜４５０℃で１分〜１０分である。 When heat treatment is performed on the above-mentioned sheet-like material and honeycomb-like material, it is preferable to carry out in an air atmosphere using a heating oven or the like. The heat treatment temperature is lower than the melting point or decomposition temperature (T1 ° C.) of the heat resistant organic component (B-1), preferably 5 ° C. to 20 ° C. lower (T1-5 to T1-20 ° C.), and the low temperature decomposition component (B-2) The treatment time is 1 minute to 60 minutes, preferably 1 minute to 30 minutes, at a decomposition temperature (T2 ° C.) or higher, preferably at a temperature of 100 ° C. to 200 ° C. or higher (T2 + 100 to T2 + 200 ° C.). Usually, it is 1 minute to 10 minutes at 350 ° C to 450 ° C.
吸着素子の平面圧縮張強度は３ｋＰａ以上が好ましい。３ｋＰａより小さい強度では吸着素子がつぶれやすく、多数の空気通路がつぶれによってなくなることで吸着素子としての性能が出ないため実用的ではない。 The planar compressive strength of the adsorption element is preferably 3 kPa or more. If the strength is less than 3 kPa, the adsorptive element is liable to be crushed, and the large number of air passages are eliminated by collapsing, so that the performance as the adsorptive element can not be obtained, which is not practical.
吸着シートの坪量（ｇ／ｍ２）に特に制限はないが、１０ｇ／ｍ２〜２００ｇ／ｍ２が好ましい。１０ｇ／ｍ２未満の場合、シートの機械強度が弱くなり、ハニカム状構造体の機械強度を維持できない。２００ｇ／ｍ２を超えると、シート厚みが厚くなりすぎるためシートの柔軟性がなくなり、シートのひび割れや吸着材の脱落が生じやすい。 The basis weight (g / m 2 ) of the suction sheet is not particularly limited, but 10 g / m 2 to 200 g / m 2 is preferable. If it is less than 10 g / m 2 , the mechanical strength of the sheet is weak and the mechanical strength of the honeycomb structure can not be maintained. When it exceeds 200 g / m 2 , the thickness of the sheet becomes too thick, so that the flexibility of the sheet is lost, and the sheet is likely to be cracked or the adsorbent falls off.
