Description

【0001】
【発明の属する技術分野】本発明は、空気中の水分およびガス状化学物質を除去するエアフィルタおよび該エアフィルタを用いた空気清浄装置に関するものである。
【0002】
【従来の技術】従来のガス状化学物質を除去する空気清浄装置では、活性炭またはガス状化学物質の反応・除去用の反応性化学物質を染込ませた活性炭の粉末を通気性のシートに添着し、そのシートを鋸歯状に折り、額縁状の枠にはめ込んだフィルタ構造のものが一般的であった。濾材の空気の通過面積は、濾材シートの折幅と単位長さ当りの折込数の増減で調整されていた。
【0003】また、活性炭に反応性化学物質を染込ませた活性炭の粉末を通気性のあるトレイにいれ、そのトレイに空気を通し、ガス状化学物質を除去する構造のものも一般的である。
【0004】更に、炭素繊維または反応性化学物質を染込ませた炭素繊維を板面に垂直に通気穴を設けたハニカム構造の板状に加工し、空気を通気口を通過させ、ガス状化学物質を除去するフィルタも一般的である。
【0005】空気中の水分の除去装置では、シリカゲル、ゼオライト等の吸湿性物質を通気性のあるトレイに入れ、該トレイに空気を通し、水分を除去する構造のものも一般的である。
【0006】これら空気中の水分またはガス状化学物質を除去する空気清浄装置では、水分またはガス状化学物質を除去する物質から発生する粉末、塵を除去するために、空気取り出し側にフィルタが設置されるのが一般的である。
【0007】従来の空気中の水分またはガス状化学物質を除去する空気清浄装置では、空気中の湿度管理とガス状化学物質濃度管理は別々に行われ、装置も別々に準備されていた。そして、最近の半導体、液晶製造工程では、水分とガス状化学物質の濃度の管理が同時に行われる傾向にある。
【0008】
【発明が解決しようとする課題】従来の空気中のガス状化学物質を除去する空気清浄装置において、活性炭またはガス状化学物質の反応・除去用の反応性化学物質を染込ませた活性炭の粉末を通気性のシートに添着し、該シートを鋸歯状に折り、額縁状の枠に嵌め込んだフィルタ構造のものでは、活性炭の添着量に限界があり、フィルタの寿命が短いという課題があった。
【0009】また、活性炭に反応性化学物質を染込ませた活性炭の粉末を通気性のあるトレイに入れ、そのトレイに空気を通し、ガス状化学物質を除去する構造のものは、ガス状化学物質成分の除去率、寿命とも優れているが、空気の通過量、通過速度でトレイの面積と厚みが決まり、小型化が困難であるという課題があった。
【0010】また、炭素繊維または反応性化学物質を染込ませた炭素繊維を板面に垂直に通気穴を設けたハニカム構造の板状に加工し、空気を通気口を通過させ、ガス状化学物質を除去するフィルタ構造のものでは、フィルタの厚みを薄くすると、空気の通過時、濾材との接触期間が短くなり、化学物質の除去が十分に行われないという課題があった。
【0011】従来の空気中の水分またはガス状化学物質を除去する空気清浄装置では、空気中の湿度管理とガス状化学物質濃度管理は別々に行われ、装置も別々に準備されていたが、装置を別々に設置すると、システム全体の小型化が困難であるという課題があった。
【0012】また、従来空気清浄装置では、水分吸着用のシリカゲル、ゼオライト等の吸湿性物質の交換時、粉末が飛び散り、部材またはパックへの充填作業が極めて困難で時間を要するという課題があった。
【0013】更に、ガス状化学物質除去用活性炭の交換でも、同じく粉塵が飛び散り、部材またはパックへの充填作業が極めて困難で時間を要すると共に、クリーン作業環境へ悪影響を及ぼすという課題があった。
【0014】本発明は、前記課題を解決すべくなされたもので、通気性のある内側部材と通気性のある外側部材との間に、水分除去用のシリカゲル、ゼオライトの粉末、またはガス状化学物質を除去する活性炭および反応・除去用の反応性化学物質を染込ませた活性炭等の吸着剤を充填し、内側部材から取り入れた空気が、前記吸着剤を通過して水分またはガス状化学物質を除去し、外側部材から清浄空気として吹き出すこともできるし、あるいは、外側部材から取り入れた空気が、前記吸着剤を通過して水分またはガス状化学物質を除去し、内側部材から清浄空気として吹き出すこともできるエアフィルタおよび該エアフィルタを用いた空気清浄装置を提供しようとするものである。
【0015】
【課題を解決するための手段】本発明は、通気性のある内側部材の外側に、空隙部を有して、通気性のある外側部材を配設し、且つ前記空隙部に水分除去用のシリカゲル、ゼオライトの粉末、またはガス状化学物質を除去する活性炭および反応・除去用の反応性化学物質を染込ませた活性炭等の吸着剤が充填され、内側部材から取り入れた空気が、前記吸着剤を通過して水分またはガス状化学物質を除去し、外側部材から清浄空気として吹き出すこともできるし、あるいは、外側部材から取り入れた空気が、前記吸着剤を通過して水分またはガス状化学物質を除去し、内側部材から清浄空気として吹き出すこともできるという手段を採用することにより、上記課題を解決した。
【0016】
【発明の実施の形態】本発明のエアフィルタおよび該エアフィルタを用いた空気清浄装置の実施の形態を図面に基づいて詳細に説明する。図1は、本発明エアフィルタの第1の実施の形態を示す縦断面図、図2は、図1のA−A線断面図である。図1および図2に示すように、本発明の第1の実施の形態におけるエアフィルタRは、汎用フィルタの素材である濾材により、外周壁1と、一方側に開口部2と、他方側に閉止壁3とをそれぞれ備えた通気性のある長方形筒状に形成された内側部材4の外側に、前記内側部材4と同一素材である濾材により、外周壁5と、一方側に開口部6と、他方側に閉止壁7とをそれぞれ備えた通気性のある長方形筒状で、且つ前記内側部材4より口径を大きく、また長く形成された外側部材8が、前記内側部材4との間に空隙部9を有して、前記各開口部2・6側を内・外側接合材10・11により連結固定し、更に前記空隙部9内に水分除去用のシリカゲル、ゼオライト粉末、またはガス状化学物質を除去する活性炭、あるいは反応・除去用の反応性化学物質を染込ませた活性炭等の吸着剤12を充填して構成されている。
【0017】前記内側部材4および外側部材8とを固定する内・外側接合材10・11は、特に限定する必要はないが、好ましくはステンレス鋼により図1に示すように構成することが推奨される。すなわち、内側部材4の開口部2の開口端部に固定する内側接合材10は、該開口端部に嵌挿できるよう、前記内側部材4より口径をやや小さく形成された内側接合筒体13の中央部外周面に、前記外側部材8より径大な鍔部14を周設して、該鍔部14より一方側を外側突部15とすると共に、前記鍔部14より他方側を内側突部16として形成されている。
【0018】また、外側部材8の開口部6の開口端部に固定する外側接合材11は、該開口端部に嵌挿できるよう、前記外側部材8より口径をやや小さく形成された外側接合筒体17の一方側端部に、前記内側接合筒体13の鍔部14の他方側面に当接固定するフランジ18を周設して形成されている。前記当接固定手段としては、ビス18a等により一体に固定することが好ましい。
【0019】前記内・外側部材4・8を内・外側接合材10・11に固定する場合、特に限定する必要はないが、好ましくは図1に示すようにして固定することが推奨される。すなわち、前記構成より成る内側接合材10を構成する内側接合筒体13の内側突部16の開口端部を、前記内側部材4の開口部2の開口端部に嵌挿して、その接合部を接着材19により密に接合固定すると共に、外側接合材11の外側接合筒体17の他方側の開口端部を、前記外側部材8の開口部6の開口端部に嵌挿して、その接合部を接着材19により密に接合固定し、更に前記外側接合材11のフランジ18を前記内側接合材10の鍔部14に当接固定して、前記内・外側部材4・8を内・外側接合材10・11に一体に固定する。
【0020】なお、前記内・外側部材4・8および内・外側接合材10・11を構成する内・外側接合筒体13・17は、断面方形状のものとして説明したが、断面円形あるいは断面楕円形であっても、本発明に採用することができる。
【0021】前記のように構成された本発明の第1の実施の形態におけるエアフィルタRの作用について説明すると、図1に示すように、内側接合材10を構成する外側突部16側から、図示していないファン等の送風手段により、内側部材4の中空部20内に入った空気21(実線矢印)は、該内側部材4の外周壁1から吸着剤12を通過して、該吸着剤12により水分またはガス状化学物質が吸着除去された清浄空気22(実線矢印)となって、前記外側部材8の外周壁5から吹き出す。
【0022】また、図示していないファン等の送風手段により、外側部材8の外周壁5から、該外側部材8内に入った空気23(点線矢印)は、前記吸着剤12を通過して、該吸着剤12により水分またはガス状化学物質が吸着除去された清浄空気24(点線矢印)となって、前記内側部材4の中空部20へ抜けて、外側突部15から吹き出す。
【0023】図3は、本発明エアフィルタの第2の実施の形態を示す縦断面図、図4は、図3のB−B線断面図である。図3および図4に示すように、本発明の第2の実施の形態におけるエアフィルタRは、前記第1の実施の形態のエアフィルタRにおける内側部材4が、2本間隔を有して並列に配設されると共に、該2本の内側部材4の外側に空隙部9を有して外側部材8が設置されたタイプである。
【0024】すなわち、内側部材4が2本並列に配設された外側に、該内側部材4の2本以上の口径の大きさに形成された外側部材8が、前記各内側部材4および外側部材8間に空隙部9を有して、前記各開口部2・6側を内・外側接合材10・11により連結固定し、更に前記空隙部9内に水分除去用のシリカゲル、ゼオライト粉末、またはガス状化学物質を除去する活性炭、あるいは反応・除去用の反応性化学物質を染込ませた活性炭等の吸着剤12を充填して形成されている。
【0025】前記第2の実施の形態におけるエアフィルタRに使用される内・外側接合材10・11は、前記第1の実施の形態におけるエアフィルタRに使用するものと基本的には同一技術思想であり、第2の実施の形態におけるエアフィルタRが2本の内側部材4を使用しているので、その分両者が大径に形成されている点と、内側接合材10の内部突部16が2本の内側部材4の各開口部2の開口端部に対応する形状となっている点が異なっているだけである。
【0026】前記のように構成された本発明の第2の実施の形態におけるエアフィルタRは、前記第1の実施の形態におけるエアフィルタRに比して、内側部材4の内壁の面積を更に大きくして、空気の通風量を増加できると共に、吸着剤12を通過する空気の通過面での均一化を図ることができ、該吸着剤12の利用効率が上がるという作用を有する。そして、その他の作用は、第1の実施の形態におけるエアフィルタRと同一であるので、説明を省略する。
【0027】なお、前記第2の実施の形態におけるエアフィルタRは、内側部材4を2本間隔を置いて並列に配設したものとして説明したが、該内側部材4を3本以上、それぞれ間隔を置いて並列に配設しても、本発明に採用することができる。
【0028】図5は、本発明エアフィルタの第3の実施の形態を示す縦断面図、図6は、図5のC−C線断面図である。前記第1の実施の形態のエアフィルタRを構成する外側部材8は、方形筒状に保型されて構成されているが、第3の実施の形態におけるエアフィルタRは、前記エアフィルタRを構成する内側部材4の外側に、前記保型性を有する外側部材8の代りに、外側部材として通気性を有するが、保型性を有しない、不織布で開口部25を備えた袋状に形成された袋体26を使用すると共に、前記開口部25にフランジ27を一体に取付け、該フランジ27をビス27a等により内側接合材10の鍔部14に固定している点が、前記エアフィルタRと異なっているだけで、その他の構成は同一である。
【0029】従って、前記エアフィルタRの場合、使用済みの吸着剤12を、ビス27aを取去って、前記袋体26に一体に取付けられたフランジ27を鍔部14から取外して、袋体26ごと簡単に取替えることができるという作用を有するが、その他の作用は前記エアフィルタRと同一であるので、説明を省略する。
【0030】なお、前記エアフィルタRにおける袋体26は、図示していないが、前記エアフィルタRにおける内側部材4を2本並列に配設したものについても、採用することができる。
【0031】図7は、前記本発明の第1〜第3の実施の形態におけるエアフィルタR〜Rを構成する内側部材4の他の実施の形態を示す縦断面図である。すなわち、前記エアフィルタR〜Rを構成する内側部材4は、汎用フィルタの素材である濾材により形成されているが、図7に示す内側部材28は、外周壁29と、一方側に開口部30と他方側に閉止壁31を備えた長方形筒状の空気通過体32が、網状または多孔状のプラスチック、金属板等の剛性の高い材料で形成されると共に、前記空気通過体32の内周壁面、あるいは外周壁面のいずれか一方(図7においては、内周壁面)に、通気性があり、且つ前記吸着剤12を構成する活性炭等の粉末、あるいは塵を通さない不織布33を層状に配設して形成されている。
【0032】なお、前記空気通過体32に不織布33を配設する場合、特に限定する必要はないが、好ましくは、図7に示すように、内側接合材10を構成する内側突部16の外周面部に、前記空気通過体32の開口端部を嵌挿すると共に、該空気通過体32の一方端縁に周設されたフランジ34を、ビス34a等により鍔部14に固定し、且つ該空気通過体32の内周面に不織布33を配設することが推奨される。
【0033】図8は、前記本発明の第1〜第2の実施の形態におけるエアフィルタR〜Rを構成する外側部材8の他の実施の形態を示す縦断面図である。すなわち、前記エアフィルタR〜Rを構成する外側部材8は、汎用フィルタの素材である濾材により形成されているが、図8に示す外側部材35は、外周壁36と、一方側に開口部37と、他方側に閉止壁38をそれぞれ備えた空気通過体39が、網状または多孔状のプラスチック、金属板等の剛性の高い材料で形成されると共に、前記空気通過体39の内周壁面、あるいは外周壁面のいずれか一方(図8においては、外周壁面)に、通気性があり、且つ前記吸着剤12を構成する活性炭等の粉末、あるいは塵を通さない不織布40を層状に配設して形成されている。
【0034】なお、前記空気通過体39に不織布40を配設する場合、特に限定する必要はないが、好ましくは、図8に示すように外側接合材11を構成する外側接合筒体17の外周面部に、前記空気通過体39の開口端部を嵌挿すると共に、該空気通過体39の一方端縁に周設されたフランジ41を、ビス41a等により外側接合材11のフランジ18に固定し、且つ該空気通過体39の外周面に不織布40を配設するようにすることが推奨される。
【0035】また、図9は、前記本発明の第3の実施の形態におけるエアフィルタRを構成する内側部材4の他の実施の形態を示す縦断面図、図10は同右側面図である。すなわち、前記エアフィルタRを構成する内側部材4は、方形筒状に形成されているのに対し、図9・図10に示す内側部材42は、四角錐形状をして形成されている。そして、前記内側部材42を先端部42aが尖った四角錐形状とすることにより、吸着剤12ごと新しい袋体26に取替える場合、前記先端部42aから内側部材42全体を吸着剤12内に容易に差込むことができるという作用を奏する。
【0036】前記内側部材42を内側接合材10に固定する場合、特に限定する必要はないが、好ましくは図9に示すように、内側接合筒体13の内側突部16の端縁部を内側部材42の開口端縁部に嵌挿して、その接合部を接着材19により密に接合固定することが推奨される。なお、図中、接合部は接着材19により密に接合固定されているが、ビスで密に接合固定してもよい。
【0037】更に、図11は、前記本発明の第3の実施の形態におけるエアフィルタRを構成する内側部材4の更に他の実施の形態を示す縦断面図、図12は同右側面図である。すなわち、前記図9、図10の内側部材42が、四角錐形状に形成されているのに対し、図11、図12に示す内側部材43は、他方端部に扁平部43aを有する略四角錐状に形成されている。そして、前記内側部材43を他方端部が扁平部43aを有する四角錐形状とすることにより、吸着剤12ごと新しい袋体26に取替える場合、前記扁平部43aから内側部材43全体を、吸着剤12内に容易に差込むことができるという作用を奏する。
【0038】前記内側部材43を内側接合材10に固定する場合、特に限定する必要はないが、好ましくは図11に示すように、内側接合筒体13の内側突部16の端縁部を内側部材43の開口端縁部に嵌挿して、その接合部を接着材19により密に接合固定することが推奨される。なお、図中、接合部は接着材19により密に接合固定されているが、ビスで密に接合固定してもよい。
【0039】また更に、図13は、前記本発明の第3の実施の形態におけるエアフィルタRを構成する内側部材4の、また更に他の実施の形態を示す縦断面図、図14は同右側面図である。すなわち、前記図9・図10が四角錐形状に形成されているのに対し、図13・図14に示す内側部材44は、円錐形状をして形成されている。そして、前記内側部材44を他方端部44aが尖った円錐形状とすることにより、吸着剤12ごと新しい袋体26に取替える場合、前記他方端部44aから内側部材44全体を吸着剤12内に容易に差込むことができるという作用を奏する。
【0040】前記内側部材44を内側接合材10に固定する場合、特に限定する必要はないが、好ましくは図13に示すように、内側接合筒体13の内側突部16の端縁部を内側部材44の開口端縁部に嵌挿して、その接合部を接着材19により密に接合固定することが推奨される。なお、図中、接合部は接着材19により密に接合固定されているが、ビスで密に接合固定してもよい。
【0041】更に、また、図15は、前記図9・図11・図13記載の内側部材42〜44の更に他の実施の形態を示す縦断面図、図16は同右側面図である。図15には前記図9に示す内側部材42を例に挙げて説明しているが、図11、図13に示す内側部材43・44にも共通である。すなわち、図9に示す内側部材42は、汎用フィルタの素材である濾材により形成されているが、図15に示す内側部材45は、四角錐形状の空気通過体46が、網状、または多孔状のプラスチック、金属板等の剛性の高い材料で形成されると共に、前記空気通過体46の内周壁面、あるいは外周壁面のいずれか一方(図15においては、内周壁面)に、通気性があり、且つ前記吸着剤12を構成する活性炭等の粉末、あるいは塵を通さない不織布47を層状に配設して形成されている。
【0042】なお、前記空気通過体46に不織布47を配設する場合、特に限定する必要はないが、好ましくは図15に示すように、内側接合材10を構成する内側突部16の外周面部に、前記空気通過体46の開口端部を嵌挿すると共に、該空気通過体46の一方端縁に周設されたフランジ48を鍔部14に固定し、且つ該空気通過体46の外周壁面に不織布47を配設することが推奨される。
【0043】図17は、本発明エアフィルタの第4の実施の形態におけるエアフィルタRと、その使用状態を示す一部を切欠いた斜視図である。前記エアフィルタRを構成する外側部材が、保型性を有しない袋体26により形成されているのに対し、エアフィルタRを構成する外側部材49は、不織布により、内部に中空部50を有する箱状の袋体51に形成されると共に、該中空部50内に吸着剤12を充填し、更に箱状の袋体51の一方側の側壁面52に、前記エアフィルタRを構成する前記内側部材42・43・44・45のいずれかを差込む挿入部53を設けて形成されている。なお、図17においては、内側部材として、前記図13に示した内側部材44を使用する状態が図示されている。
【0044】前記挿入部53は、内側部材(以下においては、円錐形状に形成された内側部材44を例として挙げて説明するが、その他の内側部材42・43・45も同様に採用できる)の先端部44aから吸着剤12内に差込むことができるように、上・下に間隔を有して挿入孔54が穿設されると共に、該挿入孔54に前記内側部材44の尖った先端部44aから挿入させることにより、破断し易いシート55を貼り付けて前記吸着剤12の流出を阻止し、更に前記挿入孔54の外周縁部に内側接合材10の鍔部14に密に当接できるよう、リング状のシリコンゴム等より成るパッキング56が突設して取付けられている。
【0045】而して、前記構成より成るエアフィルタRは、内側部材44の先端部44aをシート55に押し当てて前方側へ圧入すると、該シート55は前記先端部44aにより破断されて、前記内側部材44がテーパー状をなしているため、極めて容易に吸着剤12内に差込まれ、パッキング56が内側接合材10の鍔部14に密に当接してエアフィルタRが形成される。
【0046】前記エアフィルタRは、使用済みの吸着剤12を新しい吸着剤12と取替える場合、使用済みの吸着剤12の入った箱状の袋体51から内側部材44を抜き去り、新しい吸着剤12の入った箱状の袋体51と交換する。前記箱状の袋体51から内側部材44を抜き取る場合も、テーパー状をなしているため、極めて容易に抜き取り作業ができる。
【0047】図18は、本発明エアフィルタの第1の実施の形態におけるエアフィルタRを使用した空気清浄装置Sの縦断面図、図19は、同D−D線断面図である。すなわち、空気清浄装置Sは、前記エアフィルタRより径大に形成された一方側を開口したケーシング61を、その一方側開口部に突設されたフランジ62と、該エアフィルタRの鍔部14とで、外側接合材11のフランジ18を挟み込むようにして、ビス62a等により密に接合固定すると共に、前記ケーシング61の他方側壁面63に、口径を小さく絞った通気管64を開口連結して、該ケーシング61とエアフィルタRの外側部材8間に通気空間65を備えて形成されている。
【0048】前記構成より成る本発明空気清浄装置Sの作用について説明すると、前記空気清浄装置Sは、これを使用する装置、あるいは部材に応じて前記エアフィルタRの内側部材4から一方側に突出した内側接合材10の外側突部15から空気66を導入して、ケーシング61の通気管64から清浄空気67として吹き出すこともできるし、逆に前記通気管64から空気68を導入して、前記外側突部15から清浄空気69として吹き出すこともできる。

[0002]
2. Description of the Related Art In a conventional air purifying apparatus for removing gaseous chemical substances, activated carbon or activated carbon powder impregnated with a reactive chemical substance for reacting / removing gaseous chemical substances is attached to a breathable sheet. Then, the sheet was folded into a saw-tooth shape, and a filter structure in which the sheet was fitted into a frame-like frame was generally used. The air passage area of the filter medium was adjusted by increasing or decreasing the folding width of the filter medium sheet and the number of insertions per unit length.
[0003] Further, a structure is generally used in which activated carbon powder obtained by impregnating activated carbon with a reactive chemical substance is placed in a breathable tray, and air is passed through the tray to remove gaseous chemical substances. .
Further, carbon fiber or carbon fiber impregnated with a reactive chemical substance is processed into a honeycomb-shaped plate having a ventilation hole provided perpendicularly to the plate surface, and air is passed through a vent to form a gaseous chemical. Filters for removing substances are also common.
[0005] An apparatus for removing moisture from the air generally has a structure in which a hygroscopic substance such as silica gel or zeolite is placed in a permeable tray and air is passed through the tray to remove moisture.
[0006] In these air purifiers for removing moisture or gaseous chemical substances in the air, a filter is provided on the air take-out side in order to remove powder and dust generated from the substance for removing moisture or gaseous chemical substances. Generally, it is done.
In a conventional air purifying apparatus for removing moisture or gaseous chemical substances in air, the control of humidity and the concentration of gaseous chemical substances in air are separately performed, and the apparatuses are separately prepared. In recent semiconductor and liquid crystal manufacturing processes, there is a tendency that the concentration of moisture and the concentration of gaseous chemical substances are simultaneously controlled.

If the devices are separately installed, there is a problem that it is difficult to reduce the size of the entire system.
Further, in the conventional air purifying apparatus, when exchanging a hygroscopic substance such as silica gel or zeolite for adsorbing moisture, there is a problem that the powder scatters, and the work of filling a member or a pack is extremely difficult and time-consuming. .
[0013] Furthermore, even when the activated carbon for removing gaseous chemical substances is replaced, dust is scattered in the same manner, and it is extremely difficult and time-consuming to fill a member or a pack, and there is a problem that the clean working environment is adversely affected.
SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and a silica gel, a zeolite powder, or a gaseous chemical for removing moisture is provided between a gas-permeable inner member and a gas-permeable outer member. Filled with adsorbents such as activated carbon for removing substances and activated carbon impregnated with reactive chemicals for reaction and removal, and air taken in from the inner member passes through the adsorbent and becomes water or gaseous chemicals. Can be removed and blown out as clean air from the outer member, or the air taken in from the outer member can pass through the adsorbent to remove moisture or gaseous chemicals and blow out as clean air from the inner member. It is an object of the present invention to provide an air filter capable of performing the above-mentioned operations and an air cleaning device using the air filter.
