【0013】
また、本発明の粉塵除去方法は、自然の風又は車両の走行時の風圧を受けて前記プロペラ部材のプロペラが回転することが好ましい(請求項8記載の発明)。
【0014】
【発明の実施の形態】
以下、本発明の好ましい実施形態について説明する。本実施形態によれば、図1〜図3に示すように、粉塵除去用ユニット10は、車両の走行路線である重交通道路の両側を区画するように当該重交通道路に沿って設けられた側壁11の上部体を構成する防音壁12の内側(道路側)に取り付けて用いられる。すなわち、粉塵除去用ユニット10は、例えば1500〜2000mm程度の長さを有するユニットであって、これを防音壁12の内側に沿って当該防音壁12の略全長にわたって連接配置することにより本発明の粉塵除去構造が構成され、重交通道路の領域内に生じる粉塵を除去することが可能になる。
【0015】
本実施形態によれば、粉塵除去用ユニット10は、多数の空気導入穴13を有する有孔前面パネル14と、多数の空気流出穴(図示せず。)を有する有孔後面パネル15と、有孔前面パネル14と有孔後面パネル15との間に配設される有孔静電気帯電パネル16と、回転基端部17(図3参照)に取り付けた繊維材18(図3参照)を有孔静電気帯電パネル16の表面に接触させつつプロペラ19を回転させて有孔静電気帯電パネル16に静電気を生じさせるプロペラ部材20とからなり、空気導入開口13を介してユニット10内に導入した空気に含まれる粉塵を、帯電した静電気によって有孔静電気帯電パネル16に付着させて除去するものである。また、有孔前面パネル14と有孔後面パネル15は、幅が50〜90mm程度のステンレス製の帯状板により形成された矩形形状の矩形枠部材21をこれらの間に周縁部に沿って介在させることにより一体化されており、これによって粉塵除去用ユニット10は、全体として、例えば長さLが1500〜2000mm程度、厚さTが50〜90mm程度、高さHが500mm程度の大きさのボックス形状のユニットを構成している。
【0016】
有孔前面パネル14は、ステンレス製やアルミニウム製の網板からなり、該網板の編み目が、空気導入開口13として縦横に多数整列して開口形成されている。また、有孔前面パネル14は、その上端縁部が複数の蝶番22を介して枠部材21の上面先端縁部に接合されており、この接合部分を中心として上下に回転することにより、粉塵除去用ユニット10の前面を開閉できるようになっている。
【0017】
有孔後面パネル15は、ステンレス板やアルミニウム板からなり、直径50mm程度の円形の開口穴が、空気流出開口(図示せず。)として50mm程度の間隔をおいて縦横に多数整列して開口形成されている。
【0018】
有孔前面パネル14と有孔後面パネル15との間に介在する矩形枠部材21は、帯状のステンレス板やアルミニウム板に折り曲げ加工等を施して、縦500mm程度、横1500〜2000mm程度の矩形環状の枠部材として形成される。この枠部材21には、有孔後面パネル15が溶着接合やボルト接合等を介して一体化されると共に、有孔前面パネル14が蝶番22を介して開閉可能に接合される。また、この矩形枠部材21には、有孔後面パネル15と近接して、後述する集塵用ロ布29よりも後方の位置に、風抜き用の孔23が縁部に沿って適宜開口形成されている。
【0019】
有孔静電気帯電パネル16は、静電気発生効率、帯電効率等を鑑みて、例えば塩化ビニール系の帯電用プラスチック等、種々の帯電用のプラスチック板を用いて形成することができる。本実施形態によれば、道路付帯構造物としての耐火性能をさらに考慮して、厚さ1.5mmのポリカーボネート板を用いて形成する。有孔静電気帯電パネル16は、例えば縦450mm程度,横1450〜1950mm程度の、枠部材21の内部に容易に収容できる大きさの矩形形状を有し、周縁部が枠部材21の内側面の適宜箇所に取り付けた支持部材(図示せず。)により支持されて、有孔前面パネル14と有孔後面パネル15との間に強固に固定配置される。また、有孔静電気帯電パネル16には、有孔後面パネル15と同様に、直径50mm程度の円形の開口穴が、空気流通穴24として50mm程度の間隔をおいて縦横に多数整列して開口形成されている。
【0020】
プロペラ部材20は、有孔静電気帯電パネル16の表面に突出配置された回転軸部材25にベアリング等を介して回転可能に支持されて設けられたもので、風圧を受けて回転する回転時の径が例えば100mm程度のプラスチック製のプロペラ19と、回転軸部材25に遊嵌される回転スリーブ26と、回転スリーブ26の有孔静電気帯電パネル16側の端部に一体接合された円盤状に拡径する回転基端部17とからなる。また、回転基端部17の有孔静電気帯電パネル16側の面には、当該有孔静電気帯電パネル16の表面と接触するようにして繊維材18が植設されており、プロペラ部材20の回転によって有孔静電気帯電パネル16には、繊維材18との摩擦による静電気が生じ、生じた静電気は当該有孔静電気帯電パネル16に帯電する。また、プロペラ部材20は、縦横に例えば150mm程度のピッチで、有孔前面パネル14の全体にわたってバランス良く多数配設されており、有孔静電気帯電パネル16の全体に静電気を効率良く帯電させることができるようになっている。さらに、プロペラ部材20のプロペラ19は、有孔前面パネル14の裏面に対向して配置され、空気導入穴13を介して導入される空気の風圧を受けて容易かつスムースに回転できるようになっている。
【0021】
回転基端部17(図3参照)に取り付けられる繊維材18は、布状、毛状、ブラシ状等の繊維であって、プラスチック板との接触摩擦によって当該プラスチック板に静電気を生じさせることのできる公知の種々の繊維を用いることができる。本実施形態では、繊維材18としてアクリル繊維を使用する。
【0022】
また、本実施形態によれば、有孔前面パネル14と有孔静電気帯電パネル16との間に位置して、有孔静電気帯電パネル16の表面には、磁気帯電部材としての、径21mmの中空の磁気帯電鉄棒27が、上下に150mm程度の間隔をおいて、4段に設けられている。各磁気帯電鉄棒27には、これらの両端に各々永久磁石28が取り付けられていることにより、金属粉を吸着可能な磁力を有している。
【0023】
さらに、本実施形態によれば、有孔静電気帯電パネル16と有孔後面パネル15との間に位置して集塵用ロ布29が配設されている(図1参照)。集塵用ロ布29としては、空気を濾過することが可能な例えば公知の各種の織布や不織布を用いることができる。本実施形態では、耐久性及び経済性等を考慮して、坪量が例えば150g/m2 程度の毛織不織布を使用する。集塵用ロ布29は、縦500mm程度、横1500〜2000mm程度の、枠部材21の中空内部を覆い得る大きさの矩形形状を有し、枠部材21の内側面にその周縁部が接合されて、有孔前面パネル14の空気導入穴13から有孔後面パネル15の空気流出穴に向かって移動する空気を余すことなく通過させる。
【0024】
そして、本実施形態によれば、重交通道路の領域内に生じる粉塵を効果的に除去することができると共に、経済的に無理なく実用化を図ることができる。すなわち、自然の風による風圧、或いは車両の走行時の風圧によって、有孔前面パネル14の空気導入穴13から空気が粉塵除去用ユニット10に導入されると、この時の風圧によってプロペラ部材20のプロペラ19が回転し、繊維材18の有孔静電気帯電パネル16との摩擦によって、有孔静電気帯電パネル16には静電気が発生すると共に、発生した静電気は有孔静電気帯電パネル16に帯電する。そして、帯電した静電気によって、導入された空気中の土埃等を含む粉塵は有孔静電気帯電パネル16に吸着されて、空気中から除去されることになる。また、空気中の粉塵のうち特に鉄粉等の金属微粉は、磁力を有する磁気帯電鉄棒27に引き寄せられて吸着することによっても効果的に除去される。
【0025】
ユニット10内に導入された空気は、このようにして飛遊する粉塵が有孔静電気帯電パネル16や磁気帯電鉄棒27によって吸着除去されつつ、有孔静電気帯電パネル16の空気流通開口24を介して有孔後面パネル15側に移動する。ここで、プロペラ部材20のプロペラ19が回転していることにより、空気の流れを造って導入された空気の有孔後面パネル15側への移動を促進すると共に、重交通道路の領域内からの粉塵を含む空気のユニット10内への導入を促進することができる。
【0026】
空気流通開口24を介して有孔後面パネル15側に移動した空気は、さらに集塵用ロ布29を通過した後、有孔後面パネル15の空気流出穴を介して、粉塵が除去されたクリーンな空気として、粉塵除去用ユニット10の背面の防音壁に向かって流出排除される。ここで、有孔静電気帯電パネル16を通過して有孔後面パネル15に移動する空気は、集塵用ロ布29を通過することにより、有孔静電気帯電パネル16や磁気帯電鉄棒27に吸着されなかった粉塵の微粒子が当該集塵用ロ布29に吸着され、一層クリーンな空気となって流出排除される。
【0027】
また、本実施形態によれば、上記構成を有する粉塵除去用ユニット10を大量生産によって概ね12000円/m2 程度で製作可能であり(試算による。)、また側壁11や防音壁12の構築或いは改修作業に伴って粉塵除去用ユニット10を道路に沿って簡単に設置することができるので、経済的に無理なく容易に実用化を図ることができる。
【0028】
さらに、本実施形態によれば、防音効果も発揮することができる。すなわち、車両が通過する際の騒音は、空気の波動によって伝わるが、騒音を伴う空気は、重交通道路の領域から有孔前面パネル14の空気導入穴13を介して縮音された状態で導入された後、プロペラ19によって撹音されることになる。また、有孔静電気帯電パネル16の空気流通開口24を通過することにより、縮音、減音、拡音した後、さらに集塵用ロ布29を通過して縮音、減音、拡音を繰り返し、有孔後面パネル15の空気流出穴により縮音されつつ防音壁に向かって流出する。このように、音の縮音、拡音、撹音、曲げ音等を繰り返すことにより、重交通道路内からの騒音を効果的に緩和することができる。
【0029】
そして、本実施形態によれば、有孔静電気帯電パネル16や磁気帯電鉄棒27、集塵用ロ布29等に付着して堆積した粉塵は、定期的に清掃を行うことにより、粉塵除去用ユニット10から容易に除去することができる。すなわち、有孔前面パネル14を開いて磁気帯電鉄棒27、集塵用ロ布29等に付着した粉塵を水洗い等により清掃すると共に、集塵用ロ布29を交換することによって、粉塵除去用ユニット10の維持管理を行い、長期にわたって粉塵除去用ユニット10を使用することが可能になる。
【0030】
なお、本発明は上記実施形態に限定されることなく種々の変更が可能である。例えば、本発明は、車両の走行路線である重交通道路に限定されることなく、その他の道路や、列車が走行する線路等にも採用することができる。また、プロペラ部材は、必ずしも自然の風や車両走行時の風圧をそのまま利用して回転するものである必要はなく、電気等の動力を使って回転するものであっても良く、ソーラシステム、風力発電等による電気によって回転させても良い。さらに、磁気帯電部材は、必ずしも中空ステンレス棒からなる磁気帯電鉄棒である必要はなく、また磁気帯電させる方法としては、永久磁石による方法の他、通電することにより磁力を発生させる方法であっても良い。さらにまた、本発明は、磁気帯電部材や集塵用ロ布を取り付けて用いる必要は必ずしもない。
【0031】
また、本発明の粉塵除去用ユニットは、その寸法、形状等が上記実施形態のものと同様の構成を有する必要は必ずしもなく、本発明の粉塵除去方法は、粉塵除去用ユニットを用いて粉塵を除去するものである必要は必ずしもない。さらに、有孔前面パネルは網板である必要は必ずしもなく、板状部材に円形等の空気導入開口を多数形成したものや、開口を方向付けして車両の風圧によるユニット内への空気の導入を促進するルーバー付きの開口を形成したもの等とすることもできる。
【0032】
【発明の効果】
以上詳細に説明したように、本発明の粉塵除去用ユニット、粉塵除去構造、及び粉塵除去方法によれば、走行路線の領域内に生じる粉塵を効果的に除去することができると共に、経済的に無理なく実用化を図ることができる。
