【発明が関連する技術分野】
この発明は、空気清浄機あるいは空調機器等に搭載し、室内の汚染空気を脱臭することにより浄化する脱臭フィルターに関するものであり、特に人体臭、トイレ臭、腐敗臭を速やかに除去する脱臭フィルターの製造に関するものである。
【0002】
【従来の技術】
近年、冷暖房効果を高めるために居住空間の断熱化、気密化が進むにつれて室内空気の汚染が問題となってきた。室内空気を脱臭する方法として、換気機器を用いて新鮮な外気を導入して換気を行う方法および空気清浄機を用いて室内の汚染空気を脱臭することにより浄化する方法が考えられる。換気は脱臭効果以外に居住者が発生する二酸化炭素の排出効果と酸素の補給効果があり、換気機器と空気清浄機を同時に使用する方法が最も効果的である。空気清浄機や空調機器に搭載され、実用化されている脱臭方式には添着活性炭方式、オゾン脱臭方式、光触媒方式等がある。添着活性炭方式では添着活性炭を基材とする脱臭フィルターを送風機やダクトなどの風路に設置し、気流中の臭気ガスを速やかに化学吸着して除去するため、脱臭効果の速効性が高い。オゾン脱臭方式では風路に設置したオゾン発生器よりオゾンを発生し、気流中の臭気ガスを酸化分解することにより脱臭する。光触媒方式では微粒子状の酸化チタンに紫外線を照射して活性分子を発生させ、気流中の臭気ガスと化学反応を起こして脱臭する。上記オゾン脱臭方式および光触媒方式では化学吸着速度と比較して化学反応速度が遅いため、脱臭効果の速効性が低い。室内で発生する人体臭、トイレ臭、腐敗臭の主成分は硫化水素、メチルメルカプタンおよびアンモニアである。これらの臭気ガスを対象とし、脱臭効果の速効性が高い添着活性炭として銅イオン添着活性炭が出願されている。特開平5−7615号公報では繊維状活性炭に銅イオンを添着した消臭材料が出願されている。また、特開平9−47500号公報ではゼオライトおよび活性炭に銅イオンを添着した脱臭フィルタが出願されている。
【0003】
【発明が解決しようとする課題】
空気清浄機あるいは空調機器に搭載する脱臭フィルターは臭気ガスの除去効率が高いことと同時に風路に設置するため、圧力損失が低いことが要求される。特開平5−7615号公報に記載された繊維状活性炭に銅イオンを添着した消臭材料は図7のようにプリーツ状に成形しフィルター枠2で固定する脱臭フィルターとして用いられるが、圧力損失が高いと言う問題があった。また、特開平7−201193号公報に記載されたゼオライトおよび活性炭に銅イオンを添着した脱臭フィルターも図8のように活性炭5の粒子をフィルター枠2に充填して使用するため、圧力損失が高いと言う問題があった。本発明は空調装置との組み合わせに有効で、脱臭性能に優れると同時に圧力損失の低いフィルターを得るものである。また、本発明は、脱臭フィルターの脱臭性能および寿命に関する品質を向上させるものである。本発明は、早く且つ確実な消臭が行える脱臭フィルターの製造方法を提案するものである。また、銅イオンがフィルター全面に均一に添着される製造方法を提案するものである。
【0004】
【課題を解決するための手段】

【0014】

【0015】
【発明の実施の形態】
実施の形態1.
図1は本発明の脱臭フィルターの構造を示す斜視図である。図2はこの発明の製造方法の一つであるグラビア印刷方式の説明図である。7は風路、8は仕切り板、9は活性炭ペーパー1に銅イオンが添着処理されたハニカム形状を形成する処理された活性炭ペーパー、10は銅イオンを含む薬液、2はフィルターを形成するフィルター枠、3は印刷ロールである。
【0016】
図2の様に、セルロース繊維からなる薄い紙状のペーパーに、微粒子状活性炭を混抄した活性炭ペーパーで、先ず印刷ロール3の上に銅イオンを含む薬液が付着される。ロールを回転させることにより、印刷を行うように薬液10が活性炭ペーパー1に添着していく。この出来上がった処理済みの活性炭ペーパー9は、セルロース繊維と微粒子状活性炭を混抄した上に銅イオンが添着されている。処理された活性炭ペーパー9を加工紙としてコルゲート状に成形加工する。この成形加工された処理された活性炭ペーパー9を仕切り板8を介して積層していくことにより活性炭ペーパー9の折れ曲がった両側に風路7が形成される。活性炭ペーパー9の幅がフィルターの厚み方向長さであり、風路の長さに相当する。この様に、厚さ方向に貫通した多数の穴が空いた形の平板上の3次元構造体をハニカム状といい、この穴の中を風を通す構造である。穴の形状はコルゲート加工など加工方法にもよるが、比較的柔らかい紙状の基材のため変形し易く、ほぼ3−6角形をなす。
【0017】
この発明は、セルロース繊維と微粒子状活性炭を混抄した活性炭ペーパー1を基材として用い、同基材をハニカム状に成形して風路7を形成すると共に銅イオンを含む薬液10を添着処理したことを特徴とする脱臭フィルターである。セルロース繊維1に対し微粒子状活性炭を1−2混抄することにより、紙のように薄くて成形性の良い基材を得た。セルロース繊維100%に微粒子状活性炭を100%−200%混抄させるが、これは重量%で示しており、セルロース繊維を分散させた水溶液の中に充填物である微粒子状活性炭を混合して紙を漉くように薄い紙状の活性炭ペーパー1を得るものである。銅イオンの添着処理は基材の状態あるいはハニカム状に成形した後実施しても良い。基材の状態で銅イオンの添着処理を実施した場合には銅イオンの水溶液を吸い取り紙のように吸収し、銅イオンが基材全面に均一に添着された。また、同基材にコルゲート加工を施し、積層することによりハニカム状の成形品を得た後銅イオンの水溶液に浸漬することにより銅イオンの添着処理を実施することもできる。前者はコルゲート加工後積層してハニカム状に成形し、後者はそのままフィルター枠に組み込むことにより脱臭フィルターを得た。
【0018】
この発明においては基材をハニカム状に成形して風路を形成することにより、圧力損失を極めて低く抑えることができた。また、緻密なハニカム形状に成形することにより風路全体で脱臭するため臭気ガスの一過性除去効率を80%以上に保持することができた。なおハニカム状の材料では1平方インチあたりの穴の数を、セル数、と呼び、コルゲート加工では5号段すなわち約180セル/平方インチに対し、E号段、すなわち約320セル/平方インチのものを緻密なハニカム形状としている。本発明による脱臭フィルターは極めて低い静圧損失で高い一過性除去効率を実現しており、空気清浄機あるいは空調機器に搭載する脱臭フィルターに適するものである。特硫化水素、メチルメルカプタンおよびアンモニアの一過性除去効率に優れ、人体臭、トイレ臭、腐敗臭を速やかに除去する脱臭フィルターに適するものである。
【0019】
またこの発明の実施の形態は、セルロース繊維と活性炭繊維を混抄した活性炭ペーパー1を基材として用い、同基材をハニカム状に成形して風路7を形成すると共に銅イオンを添着処理したことを特徴とする脱臭フィルターでも良い。セルロース繊維100%に対し活性炭繊維を100−200%混抄することにより、紙のように薄くて成形性の良い基材を得た。銅イオンの添着処理は基材の状態あるいはハニカム状に成形した後実施しても良い。基材の状態で銅イオンの添着処理を実施した場合には銅イオンの水溶液を吸い取り紙のように吸収し、銅イオンが基材全面に均一に添着された。また、同基材にコルゲート加工を施し、積層することによりハニカム状の成形品を得た後銅イオンの水溶液に浸漬することにより銅イオンの添着処理を実施することもできる。前者はコルゲート加工後積層してハニカム状に成形し、後者はそのままフィルター枠に組み込むことにより脱臭フィルターを得た。
【0020】
この発明においては基材をハニカム状に成形して風路を形成することにより、圧力損失を極めて低く抑えることができた。また、比表面積が極めて大きい活性炭繊維を用いることにより、微粒子状活性炭を用いた場合よりもさらに高性能化され、緻密なハニカム形状に成形することにより臭気ガスの一過性除去効率を90%以上に保持することができた。
【0021】
またこの発明の実施の形態では、セルロース繊維と活性炭繊維に微粒子状活性炭を混抄した活性炭ペーパーを基材として用い、同基材をハニカム状に成形して風路を形成すると共に銅イオンを添着処理したことを特徴とする脱臭フィルターでも良い。セルロース繊維100%に活性炭繊維を50−100%、微粒子状活性炭を50−100%混抄することにより、紙のように薄くて成形性の良い基材を得た。銅イオンの添着処理は基材の状態あるいはハニカム状に成形した後実施しても良い。基材の状態で銅イオンの添着処理を実施した場合には銅イオンの水溶液を吸い取り紙のように吸収し、銅イオンが基材全面に均一に添着された。同基材にコルゲート加工を施し、積層することによりハニカム状の成形品を得た後銅イオンの水溶液に浸漬することにより銅イオンの添着処理を実施することもできる。前者はコルゲート加工後積層してハニカム状に成形し、後者はそのままフィルター枠に組み込むことにより脱臭フィルターを得た。
【0022】
この発明においては基材をハニカム状に成形して風路を形成することにより、圧力損失を極めて低く抑えることができた。また、高価であるが比表面積が極めて大きい活性炭繊維および低価格な微粒子状活性炭を配合して用いることにより、微粒子状活性炭のみを用いた場合よりも高性能化され、緻密なハニカム形状に成形することにより臭気ガスの一過性除去効率を85%以上に保持することができた。本発明の脱臭フィルターはセルロース繊維と微粒子状活性炭あるいは活性炭繊維を混抄した活性炭ペーパーを基材として用い、同基材をハニカム状に成形して風路を形成すると共に銅イオンを添着処理することにより、圧力損失を極めて低く抑えると共に臭気ガスの高い除去効率を発現することができた。以上の通り、この発明の風路は多数の小さい穴からなるが、ハニカムのセル数を300以上とし、フィルターの厚さ、すなわち風路の長さを20mm以下として、通風量に対し風速0.6m/秒で、圧損が2mmAq以下とし、三大悪臭である硫化水素、メチルメルカプタン、アンモニアに対し除去効率が80%以上で寿命1年以上を実現できた。またこの発明はセルロース繊維である高分子化合物の繊維をベースとして説明してきたが、セルロースはブドウ糖が環状のヘミアセタール構造を取りそのヒドロキシル基がアルコール分子や他の糖との間で水を失って縮合して配糖体を生成する時に出来る化学結合であり、繊維や粒子を水に分散して湿式方で抄紙する際に、このセルロース繊維は水分が抜ける時に繊維どおしが絡まりあい強度の強いペーパーが出来るので実用的な基材が得られる。但し、セルロース以外であっても強度の強い基材が得られる高分子化合物、例えば他の糖を使用した有機の高分子化合物の繊維や抄紙する際に繊維どおしが絡まり合う合成繊維であれば良いことは当然である。
【0023】
実施の形態2.
この発明の別の実施の形態として製造方法について説明する。図2の説明で示したように、セルロース繊維に微粒子状活性炭あるいは活性炭繊維を混抄した活性炭ペーパーに銅イオンを含む薬液を、先ず、グラビア印刷方式で添着処理し、この基材をハニカム状に成形して風路を形成した脱臭フィルターの製造方法である。また、セルロース繊維に微粒子状活性炭あるいは活性炭繊維を混抄した活性炭ペーパーに銅イオンを含む薬液をグラビア印刷方式で添着処理することにより銅イオンがフィルター全面に均一に添着された。
【0024】
図2では印刷ロール3のみ示しているがこのグラビア印刷方式では、原料ロール3に巻かれた活性炭ペーパー1がこの印刷ロール3を通り送りロールで搬送されて乾燥炉で乾燥され最後は製品である薬品で処理されたペーパーとして製品ロールに巻き取られる。この印刷ロール3は両側からグラビアしても良いが、片側をプレイロールとし反対側をグラビアロールとしても良い。グラビアロールには薬液層に漬けられた転写ロールが接触しこの薬液をグラビアロールに添着させている。この発明においては銅イオンを含む薬液をグラビア印刷方式で塗布して添着することにより銅イオンが基材全面に均一に添着され、添着量を容易にコントロールすることができた。薬液を添着された後でコルゲート状に成形されると図2の幅方向の風路全体に薬液が付着することになる。
【0025】
次に、図3に活性炭ペーパーに薬液を噴霧して添着させる方法を示す。4は内部に薬液を内蔵させ圧力を加えることにより下方の吹出し口から噴霧させる噴霧器である。セルロース繊維に微粒子状活性炭あるいは活性炭繊維を混抄した活性炭ペーパー1が生乾きの状態で銅イオンを含む薬液を噴霧して添着処理し、この基材をハニカム状に成形して風路を形成したことを特長とする脱臭フィルターの製造方法である。
【0026】
この発明においては活性炭ペーパーの抄紙工程において生乾きの状態で銅イオンを含む薬液を噴霧して添着処理することにより、抄紙工程と添着工程が連続して実施できると言うメリットがある。また、生乾きの状態で添着処理を実施することにより銅イオンの水溶液が速やかに浸透し、基材全面に均一に添着することができた。また、セルロース繊維と微粒子状活性炭あるいは活性炭繊維を混抄した活性炭ペーパーの製造工程において、活性炭ペーパーが生乾きの状態で銅イオンを含む薬液を噴霧して添着処理することにより銅イオンがフィルター全面に均一に添着された。
【0027】
【実施例】
実施例1.
この発明によるセルロース繊維と微粒子状活性炭を混抄した活性炭ペーパーを基材として用い、同基材をハニカム状に成形して風路を形成すると共に銅イオンを添着処理した脱臭フィルターの斜視図を図1に示す。図中9は銅イオンを処理した活性炭ペーパー、2はフィルター枠を示す。セルロース繊維はパルプ原料を十分にフィブリル化して用いた。微粒子状活性炭は市販の粉末状活性炭を用いた。セルロース繊維1に対し微粒子状活性炭1を混抄することにより、紙のように薄くて成形性の良い基材を得た。同基材をコルゲートマシーンを用いて5号段(1平方インチ当たりのセル数は約180と目の粗いハニカム形状である。)およびE段(1平方インチ当たりのセル数は約320と目の緻密なハニカム形状である。)のコルゲートに加工した。同コルゲートを積層することによりハニカム状の成形品を得た。ハニカム状の成形品を厚さ20mmに切断した。銅イオンの添着処理は濃度が1モル/リットルの硫酸銅水溶液に切断したハニカム成形品を10分間浸漬することにより実施した。1時間自然乾燥した後80度の電気オーブンで30分間乾燥した後、フィルター枠2に組み込むことにより脱臭フィルターを得た。
【0028】
実施例2.
この発明によるセルロース繊維と活性炭繊維を混抄した活性炭ペーパーを基材として用い、同基材をハニカム状に成形して風路を形成すると共に銅イオンを添着処理した脱臭フィルターの斜視図も図1と同様である。セルロース繊維はパルプ原料を十分にフィブリル化して用いた。活性炭繊維は市販の活性炭繊維を用いた。セルロース繊維1に対し活性炭繊維1を混抄することにより、紙のように薄くて成形性の良い基材を得た。銅イオンの添着処理は実施例4に記載したグラビア印刷方式で実施した。銅イオン添着活性炭ペーパーをコルゲートマシーンを用いて5号段およびE段のコルゲートに加工した。同コルゲートを積層することによりハニカム状の成形品を得た。ハニカム状の成形品を厚さ10mmおよび20mmに切断した後フィルター枠に組み込むことにより脱臭フィルターを得た。
【0029】
実施例3.
この発明によるセルロース繊維と活性炭繊維に微粒子状活性炭を混抄した活性炭ペーパーを基材として用い、同基材をハニカム状に成形して風路を形成すると共に銅イオンを添着処理した脱臭フィルターの斜視図も図1と同様である。セルロース繊維はパルプ原料を十分にフィブリル化して用いた。活性炭繊維は市販のものを用いた。微粒子状活性炭も市販の粉末状活性炭を用いた。セルロース繊維1に対し活性炭繊維を0.5、粉末状活性炭を0.5混抄することにより、紙のように薄くて成形性の良い基材を得た。銅イオンの添着処理は実施例5に記載した噴霧方式で実施した。銅イオン添着活性炭ペーパーをコルゲートマシーンを用いて5号段およびE段のコルゲートに加工した。同コルゲートを積層することによりハニカム状の成形品を得た。ハニカム状の成形品を厚さ10mmおよび20mmに切断した後フィルター枠に組み込むことにより脱臭フィルターを得た。
【0030】
実施例4.
セルロース繊維に微粒子状活性炭あるいは活性炭繊維を混抄した活性炭ペーパーに銅イオンを含む薬液をグラビア印刷方式で添着処理し、この基材をハニカム状に成形して風路を形成した脱臭フィルターの製造方法である。グラビア印刷方式による添着処理の原理図を図2に示す。図中1は活性炭ペーパー、3はグラビア印刷ロールを表す。グラビア印刷機に活性炭ペーパーを通し、グラビア印刷ロールに硫酸銅水溶液を所定量含ませて活性炭ペーパーに転写することにより全面に均一に添着することができる。この方式で得られた銅イオン添着活性炭ペーパーを実施例2で用いた。
【0031】
実施例5.
セルロース繊維に微粒子状活性炭あるいは活性炭繊維を混抄した活性炭ペーパーが生乾きの状態で銅イオンを含む薬液を噴霧して添着処理し、この基材をハニカム状に成形して風路を形成したことを特長とする脱臭フィルターの製造方法である。噴霧方式による添着処理の原理図を図3に示す。図中1は活性炭ペーパー、4は噴霧器を表す。小型の抄紙機で活性炭ペーパーを抄紙し、乾燥工程から出てきた生乾きの活性炭ペーパーに硫酸銅水溶液を所定量噴霧することにより全面に均一に添着することができる。この方式で得られた銅イオン添着活性炭ペーパーを実施例3で用いた。この方式では活性炭ペーパーの抄紙と銅イオンの添着が同一ラインで製造できると言うメリットがある。
【0032】
比較例1.
従来例として粒子径が5mm程度の破砕炭を濃度が1モル/リットルの硫酸銅水溶液に10分間浸漬して乾燥し、銅イオン添着粒子状活性炭を得た。図8に示すような厚さが20mmで格子状のフィルター枠の下面に不織布を張り合わせ、各格子の中に上記粒子状活性炭を充填した後フィルター枠の上面にも不織布を張り合わせて脱臭フィルターを作製した。同脱臭フィルターの斜視図を図8に示す。
【0033】
比較例2.
従来例として活性炭繊維を濃度が1モル/リットルの硫酸銅水溶液に10分間浸漬して乾燥し、銅イオン添着活性炭繊維を得た。同活性炭繊維をプリーツ状に折り込んで厚さが20mmのフィルター枠に組み込んで脱臭フィルターを作製した。同脱臭フィルターの斜視図を図7に示す。
【0034】
上記実施例および比較例で得た脱臭フィルターの静圧損失および臭気ガスの一過性除去効率を測定し、性能を比較した。脱臭フィルターの静圧損失は微小圧力計を用い、0.6m/sの風速で脱臭フィルターの前後における静圧差を測定することにより求めた。実施例の5号段の脱臭フィルター(180セル)の静圧損失は約0.5mmAq、E段の脱臭フィルター(320セル)の静圧損失は約1.0mmAqと極めて低かった。比較例1および2の脱臭フィルターの静圧損失はそれぞれ3および5mmAqと高かった。次に脱臭フィルターの硫化水素、メチルメルカプタンおよびアンモニアに対する一過性除去効率を測定した。脱臭フィルターの一過性除去効率の測定は所定濃度の臭気ガスを含む空気を所定の風速で流せるようなダクトの下流側に臭気センサを設置した評価装置を用いて行った。硫化水素およびメチルメルカプタンは1ppm、アンモニアは10ppmの臭気濃度(入口濃度)の空気を0.6m/sの風速で上記ダクトに流し、10cm角にカットした脱臭フィルターを上記ダクトに挿入し、脱臭後の臭気濃度(出口濃度)を臭気センサーで測定して図4に示す式により一過性除去効率を算出した。
【0035】
実施例の5号段の脱臭フィルター(180セル)の一過性除去効率は60%程度であったが、E段の脱臭フィルター(320セル)の一過性除去効率は80%以上と高かった。図5に実施例のE段の脱臭フィルターの静圧損失および硫化水素、メチルメルカプタンおよびアンモニアに対する一過性除去効率の測定結果を
纏めて示す。また、比較例の脱臭フィルターの測定結果も図5に併記する。
【0036】
図5より明らかなように比較例1の脱臭フィルターは3mmAqの静圧損失で60−70%の一過性除去効率を実現している。比較例2の脱臭フィルターは5mmAqの静圧損失で90−100%の一過性除去効率を実現している。これに対して実施例1の脱臭フィルターは僅か1mmAqの静圧損失で80%以上の一過性除去効率を実現しており、実施例2および3の脱臭フィルターは僅か1mmAqの静圧損失で90%以上および85%以上の一過性除去効率を実現している。
【0037】
実施の形態3.
図6は天井直付け扇風機の構造を説明する図である。11はモータ15とファン16を内蔵する扇風機のケーシング、12はケーシング11の表面に取り付けられ吸込み口19と吹出し口20を有するグリル、13はこの発明で説明されてきたグリルの内側に取り付けられた脱臭フィルター、14はケーシング内部を吸込み側の中央部と吹出し側の外周部を区分けしている内板、18はファン16の内部でモーター軸17を固定しファン16とモーター15を一体に回転させるファン取付ボルト、22はケーシング11を天井21に固定する送風機固定ねじである。モーターの固定子はケーシング11に固定され、モーター15の回転子が回転するとファン16が回転して室内から空気を吸込み口19と脱臭フィルター13を通して吸込まれ、プロペラファンの外周側に設けた遠心ディフューザー回路を通して吹出し口20から空気を吹出す。
【0038】
この構造ではケーシング11はほぼ正方形の周囲を有し、吸込みは中央全体から吸込み、吹出しは4角形の2面の吹出し口20から吹出し、他の2面はグリルで蓋をされている。プロペラファンを使用し遠心ディフューザー回路を通すことにより少ない電力で大風量を得るとともに低騒音の扇風機が得られる。更に脱臭フィルター13は中央全体に設けられ面積を広く取れるので風速を押さえるとともにハニカム状に形成された風路に設けられ銅イオン処理された活性炭ペーパーにより効果的な脱臭が行われる。吹出し口が対象の2面に絞られているので吹出した大風量は天井から床に向かい高速で吹出される。更に絞られた2面の側から空気が中央に回り易いので部屋全体を空気が循環する。
【0039】
平べったいプロペラファンと遠心ディフューザー回路を使用して高さを押さえることができ、幅のあるすなわち風路の長い脱臭フィルターを利用することが出来る。この結果病院や高齢者施設など公共の広い部屋や廊下、トイレなどに後から天井にねじで簡単に取り付けることが出来る。これにより、体臭、トイレ臭、不は異臭など気になる匂いを取り除くことが出来る。家庭内の居室に対しても簡単に後から取り付けて扇風機による涼風による人のからだに良い冷却を行うことが出来る。
【0040】
この天井直付け扇風機の代りに同じ送風機構造で天井に埋め込まれ、外部につながる換気ファンが設けられたダクトをケーシングの横から直接ファンの吸い込み部であるファンと脱臭フィルターの間にケーシングと内板を貫通して外気を導くことでもよい。冷暖房効果を高めるために居住空間の断熱化、気密化が進むにつれて室内空気の汚染が問題となって来ているが、この構成で、室内空気を脱臭する方法として、換気ファンとダクトを介して新鮮な外気を導入して換気を行う方法および脱臭フィルターを用いて室内の空気を循環させて汚染空気を脱臭することにより浄化する方法の組み合わせが得られる。換気は脱臭効果以外に居住者が発生する二酸化炭素の排出効果と酸素の補給効果があり、このような換気機器と脱臭フィルターを同時に使用する方法が最も効果的である。
【0041】
【発明の効果】
分子化合物の繊維と粒子状および繊維状の少なくとも一つの活性炭とを混抄した活性炭ペーパーを用いた基材と、基材を成形して厚さ方向に貫通した多数の穴を設け平板状を形成させた構造体と、を備え、この構造体の穴を風路とするとともに基材に銅イオンを添着処理したので、低圧損で効果的に脱臭できる装置が得られる。
【0042】
また、活性炭量はセルロース量100%に対し100%−200%を混抄するので、紙のように薄い活性炭ペーパーが得られ小型化が可能になる。
【0043】
さらに、基材にて形成した風路は、所定の長さを有するので、十分な脱臭効果が得られる。
【0044】
高分子化合物の繊維と活性炭繊維および微粒子状活性炭の少なくとも一つとを混抄して活性炭ペーパーを形成するステップと、活性炭ペーパーを基材として用い、この基材に銅イオンを含む薬液を添着処理するステップと、基材を成形して風路を形成するステップと、を備え、薬液はロールに付着させて基材に転写させるので、活性炭ペーパーに薬液を均一に添着させることが出来る。
【0045】
また、活性炭ペーパーに銅イオンを含む薬液を噴霧または浸漬して添着処理したので、薬液を確実に全面に添着できる。
【0046】
さらに、活性炭ペーパーが生乾きの状態で銅イオンを含む薬液を噴霧または浸漬して添着処理したので、薬液が浸透し品質の安定した製品を製造できる。

TECHNICAL FIELD OF THE INVENTION
  The present invention relates to a deodorizing filter that is mounted on an air purifier or an air conditioner, and purifies by deodorizing indoor polluted air, and in particular, a deodorizing filter that quickly removes human body odor, toilet odor, and rotten odor. It relates to manufacturing.
[0002]
[Prior art]
  In recent years, the contamination of indoor air has become a problem as the heat insulation and airtightness of living spaces progress in order to enhance the heating and cooling effect. As a method of deodorizing indoor air, a method of ventilating by introducing fresh outside air using a ventilation device and a method of purifying by deodorizing indoor contaminated air using an air purifier can be considered. Ventilation has the effect of discharging carbon dioxide generated by residents and the effect of supplying oxygen in addition to the deodorizing effect, and the method of using a ventilation device and an air purifier at the same time is the most effective. Deodorizing methods installed in air cleaners and air conditioners and put into practical use include an impregnated activated carbon method, an ozone deodorizing method, and a photocatalytic method. In the impregnated activated carbon method, a deodorizing filter based on the impregnated activated carbon is installed in an air passage such as a blower or a duct, and the odorous gas in the airflow is quickly chemisorbed and removed, so that the deodorizing effect is fast. In the ozone deodorization method, ozone is generated from an ozone generator installed in the air passage and deodorized by oxidative decomposition of odorous gas in the airflow. In the photocatalytic method, fine particles of titanium oxide are irradiated with ultraviolet rays to generate active molecules, which deodorize by causing a chemical reaction with the odorous gas in the airflow. In the ozone deodorization method and the photocatalyst method, since the chemical reaction rate is slower than the chemical adsorption rate, the rapid effect of the deodorizing effect is low. The main components of the human body odor, toilet odor and rot odor generated indoors are hydrogen sulfide, methyl mercaptan and ammonia. Copper ion impregnated activated carbon has been filed as an impregnated activated carbon that targets these odor gases and has high deodorizing effect. Japanese Patent Application Laid-Open No. 5-7615 has filed an application for a deodorizing material in which copper ions are impregnated with fibrous activated carbon. Japanese Patent Application Laid-Open No. 9-47500 has applied for a deodorizing filter in which copper ions are added to zeolite and activated carbon.
[0003]
[Problems to be solved by the invention]
  A deodorizing filter mounted on an air purifier or an air conditioner is required to have a low pressure loss because it is installed in an air passage at the same time as having high odor gas removal efficiency. The deodorant material in which copper ions are attached to fibrous activated carbon described in JP-A-5-7615 is used as a deodorizing filter formed into a pleat shape and fixed with a filter frame 2 as shown in FIG. There was a problem of being expensive. Moreover, since the deodorizing filter in which copper ions are impregnated with zeolite and activated carbon described in JP-A-7-201193 is used by filling the filter frame 2 with particles of activated carbon 5 as shown in FIG. 8, the pressure loss is high. There was a problem. The present invention is effective in combination with an air conditioner, and obtains a filter having excellent deodorization performance and low pressure loss. Moreover, this invention improves the quality regarding the deodorizing performance and lifetime of a deodorizing filter. The present invention proposes a method for producing a deodorizing filter capable of quick and reliable deodorization. The present invention also proposes a manufacturing method in which copper ions are uniformly attached to the entire surface of the filter.

DETAILED DESCRIPTION OF THE INVENTION
Embodiment 1 FIG.
  FIG. 1 is a perspective view showing the structure of the deodorizing filter of the present invention. FIG. 2 is an explanatory view of a gravure printing method which is one of the manufacturing methods of the present invention. 7 is an air path, 8 is a partition plate, 9 is activated carbon paper that forms a honeycomb shape in which activated carbon paper 1 is copper-attached, 10 is a chemical solution containing copper ions, and 2 is a filter frame that forms a filter. Reference numeral 3 denotes a printing roll.
[0016]
  As shown in FIG. 2, a chemical solution containing copper ions is first attached onto the printing roll 3 by using activated carbon paper obtained by mixing fine activated carbon with a thin paper-like paper made of cellulose fibers. By rotating the roll, the chemical solution 10 is attached to the activated carbon paper 1 so as to perform printing. The finished treated activated carbon paper 9 is a mixture of cellulose fibers and particulate activated carbon, and copper ions are attached thereto. The treated activated carbon paper 9 is formed into a corrugated shape as a processed paper. The formed activated carbon paper 9 is laminated through the partition plate 8, whereby the air path 7 is formed on both sides of the activated carbon paper 9 that are bent. The width of the activated carbon paper 9 is the length in the thickness direction of the filter, and corresponds to the length of the air path. In this way, a three-dimensional structure on a flat plate in which a large number of holes penetrating in the thickness direction are formed is called a honeycomb shape, and the structure allows air to pass through the holes. Although the shape of the hole depends on the processing method such as corrugation, it is easily deformed because of a relatively soft paper-like base material, and forms almost a 3-6 square.
[0017]
  In the present invention, activated carbon paper 1 obtained by mixing cellulose fibers and fine activated carbon is used as a base material, and the base material is formed into a honeycomb shape to form an air passage 7 and a chemical solution 10 containing copper ions is attached. It is a deodorizing filter characterized by this. By subjecting the cellulose fiber 1 to 1-2 fine particles of activated carbon, a base material that is thin like paper and has good moldability was obtained. 100% -200% cellulose fiber is mixed with 100% -200% fine particle activated carbon. This is indicated by weight%, and a paper is prepared by mixing fine particle activated carbon as a filler in an aqueous solution in which cellulose fiber is dispersed. A thin paper-like activated carbon paper 1 is obtained. The copper ion deposition treatment may be performed after the substrate is formed or formed into a honeycomb. When the copper ion deposition treatment was carried out in the state of the substrate, the copper ion aqueous solution was absorbed like a blotting paper, and the copper ions were uniformly deposited on the entire surface of the substrate. Moreover, the corrugating process is performed on the base material, and a honeycomb-shaped formed product is obtained by laminating, and then the copper ion is attached by immersing it in an aqueous solution of copper ions. The former was laminated after corrugating and formed into a honeycomb shape, and the latter was directly incorporated into a filter frame to obtain a deodorizing filter.
[0018]
  In the present invention, the pressure loss can be suppressed extremely low by forming the air channel by forming the base material into a honeycomb shape. In addition, since the deodorization was performed on the entire air passage by forming into a dense honeycomb shape, the transient removal efficiency of odor gas could be maintained at 80% or more. In the honeycomb-shaped material, the number of holes per square inch is referred to as the number of cells, and in corrugating, the number E, ie, about 180 cells / square inch, whereas the number E, ie, about 320 cells / square inch. The thing is made into the dense honeycomb shape. The deodorizing filter according to the present invention achieves a high temporary removal efficiency with a very low static pressure loss, and is suitable for a deodorizing filter mounted on an air purifier or an air conditioner. It is excellent in the temporary removal efficiency of special hydrogen sulfide, methyl mercaptan and ammonia, and is suitable for a deodorizing filter that quickly removes human body odor, toilet odor and rot odor.
[0019]
  In the embodiment of the present invention, activated carbon paper 1 obtained by mixing cellulose fibers and activated carbon fibers is used as a base material, and the base material is formed into a honeycomb shape to form an air passage 7 and copper ions are attached. A deodorizing filter characterized by the above may be used. By mixing 100-200% of the activated carbon fibers with 100% of the cellulose fibers, a base material that is thin like paper and good in moldability was obtained. The copper ion deposition treatment may be performed after the substrate is formed or formed into a honeycomb. When the copper ion deposition treatment was carried out in the state of the substrate, the copper ion aqueous solution was absorbed like a blotting paper, and the copper ions were uniformly deposited on the entire surface of the substrate. Moreover, the corrugating process is performed on the base material, and a honeycomb-shaped formed product is obtained by laminating, and then the copper ion is attached by immersing it in an aqueous solution of copper ions. The former was laminated after corrugating and formed into a honeycomb shape, and the latter was directly incorporated into a filter frame to obtain a deodorizing filter.
[0020]
  In the present invention, the pressure loss can be suppressed extremely low by forming the air channel by forming the base material into a honeycomb shape. In addition, by using activated carbon fibers with a very large specific surface area, the performance is further improved than when fine activated carbon is used, and the transient removal efficiency of odor gas is 90% or more by molding into a dense honeycomb shape. Was able to hold on.
[0021]
  In the embodiment of the present invention, activated carbon paper in which finely divided activated carbon is mixed with cellulose fibers and activated carbon fibers is used as a base material, and the base material is formed into a honeycomb shape to form an air passage and copper ions are attached. A deodorizing filter characterized by the above may be used. By mixing 50% to 100% activated carbon fiber and 50% to 100% particulate activated carbon to 100% cellulose fiber, a base material that is as thin as paper and has good moldability was obtained. The copper ion deposition treatment may be performed after the substrate is formed or formed into a honeycomb. When the copper ion deposition treatment was carried out in the state of the substrate, the copper ion aqueous solution was absorbed like a blotting paper, and the copper ions were uniformly deposited on the entire surface of the substrate. The base material can be corrugated and laminated to obtain a honeycomb-shaped formed article, and then immersed in an aqueous solution of copper ions to perform a copper ion addition process. The former was laminated after corrugating and formed into a honeycomb shape, and the latter was directly incorporated into a filter frame to obtain a deodorizing filter.
[0022]
  In the present invention, the pressure loss can be suppressed extremely low by forming the air channel by forming the base material into a honeycomb shape. In addition, by using an activated carbon fiber that is expensive but has an extremely large specific surface area and a low-priced particulate activated carbon, the performance is improved compared with the case where only the particulate activated carbon is used, and a dense honeycomb shape is formed. As a result, the transient removal efficiency of the odor gas could be maintained at 85% or more. The deodorizing filter of the present invention uses activated carbon paper mixed with cellulose fibers and particulate activated carbon or activated carbon fibers as a base material, and the base material is formed into a honeycomb shape to form an air path and copper ions are attached. In addition, the pressure loss was suppressed to a very low level, and high odor gas removal efficiency was achieved. As described above, the air passage of the present invention is composed of a large number of small holes. The number of cells of the honeycomb is set to 300 or more, the filter thickness, that is, the length of the air passage is set to 20 mm or less, and the air velocity is set to 0. At 6 m / sec, the pressure loss was 2 mmAq or less, and the removal efficiency was 80% or more against the three major odors of hydrogen sulfide, methyl mercaptan, and ammonia, and a lifetime of 1 year or more was realized. Although the present invention has been described based on the fiber of a polymer compound that is a cellulose fiber, cellulose has a cyclic hemiacetal structure in which glucose loses water between alcohol molecules and other sugars. This is a chemical bond that can be formed when condensing to produce glycosides. When fiber or particles are dispersed in water and paper is made in a wet process, the cellulose fibers are entangled with each other when moisture is lost. A strong paper can be made, so a practical base material can be obtained. However, other than cellulose, a polymer compound that can provide a strong base material, for example, an organic polymer compound fiber using other sugars or a synthetic fiber in which fibers are entangled when paper is made. It is natural to do it.
[0023]
Embodiment 2. FIG.
  A manufacturing method will be described as another embodiment of the present invention. As shown in the explanation of FIG. 2, a chemical solution containing copper ions is first applied to activated carbon paper obtained by mixing finely divided activated carbon or activated carbon fibers with cellulose fibers by a gravure printing method, and this substrate is formed into a honeycomb shape. This is a method for producing a deodorizing filter in which an air passage is formed. Moreover, the chemical | medical solution containing a copper ion was attached to the activated carbon paper which mixed the particulate activated carbon or the activated carbon fiber with the cellulose fiber by the gravure printing system, and the copper ion was uniformly attached to the filter whole surface.
[0024]
  Although only the printing roll 3 is shown in FIG. 2, in this gravure printing method, the activated carbon paper 1 wound around the raw material roll 3 is conveyed by the feed roll through the printing roll 3 and dried in the drying furnace, and finally the product. It is wound on a product roll as a paper treated with chemicals. The printing roll 3 may be gravure from both sides, but one side may be a play roll and the other side may be a gravure roll. The gravure roll is brought into contact with a transfer roll immersed in the chemical solution layer, and this chemical solution is attached to the gravure roll. In the present invention, a chemical solution containing copper ions is applied and attached by a gravure printing method, so that copper ions are uniformly attached to the entire surface of the substrate, and the amount of attachment can be easily controlled. When the corrugated shape is formed after the chemical solution is attached, the chemical solution adheres to the entire air passage in the width direction of FIG.
[0025]
  Next, FIG. 3 shows a method of spraying and attaching a chemical solution to activated carbon paper. Reference numeral 4 denotes a sprayer in which a chemical solution is housed and sprayed from a lower outlet by applying pressure. The activated carbon paper 1 in which finely divided activated carbon or activated carbon fiber is mixed with cellulose fiber is spray-dried with a chemical solution containing copper ions in a freshly dried state, and this substrate is formed into a honeycomb shape to form an air passage. This is a method for producing a deodorizing filter.
[0026]
  In the present invention, there is an advantage that the paper making process and the attaching process can be carried out continuously by spraying a chemical solution containing copper ions in the paper making process of the activated carbon paper and spraying it with a chemical solution containing copper ions. Moreover, the copper ion aqueous solution permeated rapidly by carrying out the adhesion treatment in the state of being dried, and it was possible to uniformly adhere to the entire surface of the substrate. In addition, in the manufacturing process of activated carbon paper that is a mixture of cellulose fiber and particulate activated carbon or activated carbon fiber, copper ions are uniformly applied to the entire filter surface by spraying a chemical solution containing copper ions while the activated carbon paper is still dry. It was attached.

A non-woven fabric is pasted on the lower surface of a grid-like filter frame with a thickness of 20 mm as shown in FIG. 8, and the above-mentioned particulate activated carbon is filled in each lattice, and then the non-woven fabric is pasted on the upper surface of the filter frame to produce a deodorizing filter. did. A perspective view of the deodorizing filter is shown in FIG.
[0033]
Comparative Example 2
  As a conventional example, the activated carbon fiber was immersed in an aqueous copper sulfate solution having a concentration of 1 mol / liter for 10 minutes and dried to obtain a copper ion-impregnated activated carbon fiber. The activated carbon fiber was folded into a pleat shape and incorporated in a filter frame having a thickness of 20 mm to produce a deodorizing filter. A perspective view of the deodorizing filter is shown in FIG.
[0034]
  The static pressure loss and transient removal efficiency of odor gas of the deodorizing filters obtained in the above Examples and Comparative Examples were measured, and the performance was compared. The static pressure loss of the deodorizing filter was determined by measuring the difference in static pressure before and after the deodorizing filter at a wind speed of 0.6 m / s using a micro pressure gauge. The static pressure loss of the No. 5 stage deodorizing filter (180 cells) of the example was about 0.5 mmAq, and the static pressure loss of the E stage deodorizing filter (320 cells) was about 1.0 mmAq. The static pressure loss of the deodorizing filters of Comparative Examples 1 and 2 was as high as 3 and 5 mmAq, respectively. Next, the transient removal efficiency for hydrogen sulfide, methyl mercaptan and ammonia of the deodorizing filter was measured. The transient removal efficiency of the deodorizing filter was measured using an evaluation device in which an odor sensor was installed on the downstream side of the duct so that air containing a predetermined concentration of odor gas could flow at a predetermined wind speed. Hydrogen sulfide and methyl mercaptan 1ppm, ammonia 10ppm odor concentration (inlet concentration) flowed through the duct at a wind speed of 0.6m / s, a 10cm square cut deodorization filter was inserted into the duct, and after deodorization The odor concentration (exit concentration) was measured with an odor sensor, and the transient removal efficiency was calculated by the equation shown in FIG.
[0035]
  The transient removal efficiency of the No. 5 stage deodorization filter (180 cells) of the Example was about 60%, but the transient removal efficiency of the E stage deodorization filter (320 cells) was as high as 80% or more. . FIG. 5 shows the measurement results of the static pressure loss and the transient removal efficiency with respect to hydrogen sulfide, methyl mercaptan and ammonia of the deodorizing filter of stage E of the example.
Shown together. Moreover, the measurement result of the deodorizing filter of the comparative example is also shown in FIG.
[0036]
  As is apparent from FIG. 5, the deodorizing filter of Comparative Example 1 achieves a transient removal efficiency of 60-70% with a static pressure loss of 3 mmAq. The deodorizing filter of Comparative Example 2 achieves a transient removal efficiency of 90-100% with a static pressure loss of 5 mmAq. In contrast, the deodorizing filter of Example 1 achieved a transient removal efficiency of 80% or more with a static pressure loss of only 1 mmAq, and the deodorizing filters of Examples 2 and 3 were 90 with a static pressure loss of only 1 mmAq. % Or more and 85% or more transient removal efficiency.
[0037]
Embodiment 3 FIG.
  FIG. 6 is a diagram for explaining the structure of a ceiling-mounted fan. Reference numeral 11 denotes a fan casing incorporating a motor 15 and a fan 16, reference numeral 12 denotes a grille which is attached to the surface of the casing 11 and has a suction port 19 and a blowout port 20, and reference numeral 13 denotes an inner side of the grill described in the present invention. A deodorizing filter, 14 is an inner plate that separates the inside of the casing from the central portion on the suction side and the outer peripheral portion on the outlet side, and 18 is a motor 16 that fixes the motor shaft 17 inside the fan 16 and rotates the fan 16 and the motor 15 together. A fan mounting bolt 22 is a blower fixing screw for fixing the casing 11 to the ceiling 21. The stator of the motor is fixed to the casing 11, and when the rotor of the motor 15 rotates, the fan 16 rotates to suck air from the room through the air inlet 19 and the deodorizing filter 13, and a centrifugal diffuser provided on the outer peripheral side of the propeller fan. Air is blown out from the outlet 20 through the circuit.
[0038]
  In this structure, the casing 11 has a substantially square periphery, the suction is sucked from the entire center, the blowout is blown out from the two blowout ports 20 of the quadrangular shape, and the other two faces are covered with a grill. By using a propeller fan and passing through a centrifugal diffuser circuit, a large amount of air can be obtained with a small amount of power and a low noise fan can be obtained. Further, since the deodorizing filter 13 is provided in the entire center and can take a large area, effective deodorization is performed by the activated carbon paper which suppresses the wind speed and is provided in the air passage formed in a honeycomb shape and is treated with copper ions. Since the outlet is restricted to the two sides of the target, the large amount of air blown out is blown at high speed from the ceiling to the floor. Furthermore, air circulates in the entire room because air tends to go to the center from the two narrowed surfaces.
[0039]
  A flat propeller fan and centrifugal diffuser circuit can be used to control the height, and a wide deodorizing filter with a long air path can be used. As a result, it can be easily attached to the ceiling from behind in large public rooms such as hospitals and elderly facilities, corridors, and toilets. As a result, body odor, toilet odor, and unpleasant odor can be removed. It can be easily attached to the living room in the home and can cool the human body with the cool air from the fan.
[0040]
  Instead of this direct fan mounted on the ceiling, the duct with the same blower structure embedded in the ceiling and provided with a ventilation fan connected to the outside is directly placed between the fan and the deodorizing filter from the side of the casing between the fan and the deodorizing filter. It is also possible to guide the outside air through. Contamination of indoor air has become a problem as heat insulation and airtightness of living spaces progress to enhance the air conditioning effect. With this configuration, as a method of deodorizing indoor air, ventilation fans and ducts are used. A combination of a method of performing ventilation by introducing fresh outside air and a method of purifying by deodorizing contaminated air by circulating indoor air using a deodorizing filter is obtained. Ventilation has the effect of discharging carbon dioxide generated by residents and the effect of supplying oxygen in addition to the deodorizing effect, and the method of using such a ventilation device and the deodorizing filter at the same time is the most effective.
