Abstract
Description
また、ディーゼルエンジンや焼却炉から排出される気体には、有害物質として粒子状物質が多く含まれている。その粒子状物質を除去する技術として、特許文献1には、多数の孔をあけた耐熱板からなる濾過装置で粒子状物質を捕捉する技術が開示されている。
さらに、酸化反応によって生み出される二酸化炭素は、地球規模の温暖化を招く温室効果ガスであり、この二酸化炭素の放出量を減量することが国際的な課題となっている。
また、粒子状物質は大気中に浮遊し易く、人間の気道や肺に沈着して健康を損ねるので、大気汚染の主要因とされており、さらなる除去が望まれている。
また、気体中の有害物質を除去する方法であって、少なくとも光合成菌を含む菌体群からなる微生物と、酵母菌を含む菌体群からなる微生物と、乳酸菌を含む菌体群からなる微生物とを含有した液体中に、有害物質を含んだ気体を放出して、該気体中の有害物質を除去する一次工程と、少なくとも光合成菌を含む菌体群からなる微生物と、酵母菌を含む菌体群からなる微生物と、乳酸菌を含む菌体群からなる微生物とを含有した焼成体に、前記一次工程を通過した気体を接触させて、気体中に残留する有害物質をさらに除去する二次工程とを有することを特徴とする有害物質除去方法とする場合もある。
さらに、気体中の有害物質を除去する方法であって、少なくとも光合成菌を含む菌体群からなる微生物と、酵母菌を含む菌体群からなる微生物と、乳酸菌を含む菌体群からなる微生物とを含有した液体中に、有害物質を含んだ気体を放出して、該気体中の有害物質を除去する一次工程と、少なくとも光合成菌を含む菌体群からなる微生物と、酵母菌を含む菌体群からなる微生物と、乳酸菌を含む菌体群からなる微生物とを含有した焼成体に、前記一次工程を通過した気体を接触させて、気体中に残留する有害物質をさらに除去する二次工程と、前記二次工程を通過した気体から、該気体中に残留する有害物質をさらに除去する残留有害物質除去工程とを有することを特徴とする有害物質除去方法とする場合もある。
さらに、気体中の有害物質を除去する方法であって、少なくとも光合成菌を含む菌体群からなる微生物と、酵母菌を含む菌体群からなる微生物と、乳酸菌を含む菌体群からなる微生物とを含有した液体中に、有害物質を含んだ気体を放出して、該気体中の有害物質を除去する一次工程と、前記一次工程を通過した気体から、該気体中に残留する有害物質をさらに除去する残留有害物質除去工程と、少なくとも光合成菌を含む菌体群からなる微生物と、酵母菌を含む菌体群からなる微生物と、乳酸菌を含む菌体群からなる微生物とを含有した焼成体に、前記残留有害物質除去工程を通過した気体を接触させて、気体中に残留する有害物質をさらに除去する二次工程とを有することを特徴とする有害物質除去方法とする場合もある。
さらに、気体中の有害物質を除去する方法であって、少なくとも光合成菌を含む菌体群からなる微生物と、酵母菌を含む菌体群からなる微生物と、乳酸菌を含む菌体群からなる微生物とを含有した焼成体を、少なくとも光合成菌を含む菌体群からなる微生物と、酵母菌を含む菌体群からなる微生物と、乳酸菌を含む菌体群からなる微生物とを含有した液体中に配し、該液体中に有害物質を含んだ気体を放出して、該気体中の有害物質を除去する一次工程と、前記一次工程を通過した気体から、該気体中に残留する有害物質をさらに除去する残留有害物質除去工程とを有することを特徴とする有害物質除去方法とする場合もある。
本実施例では、内燃機関や焼却炉(A)から排出された一酸化炭素、二酸化炭素、粒子状物質などの有害物質を含んだ気体が、有害物質処理工程Bに導入されて処理された後に排出(F)される方法を採用している。
有害物質処理工程Bでは、液体Sに含有された微生物に気体を反応させて処理を行なう。
前記液体Sは、少なくとも光合成菌を含む菌体群からなる微生物と、酵母菌を含む菌体群からなる微生物と、乳酸菌を含む菌体群からなる微生物とを含有している。
これらの微生物は、液体中を通過する前記気体と反応することによって、その気体中に含まれている一酸化炭素、二酸化炭素、粒子状物質などの有害物質が除去処理される。
本実施例にて採用した処理装置は、処理対象となる気体を導入する導入孔2dと、処理済の気体を外部に排出する排出孔2eを備え、その導入孔と排出孔以外は密閉状に形成された有害物質処理槽2aと、その有害物質処理槽2a内に収容される上述した液体Sとで構成されており、上述した有害物質処理工程Bは、この処理装置の内部で処理される。
導入孔2dは、有害物質処理槽2aの下部領域2cに設けられており、この導入孔2dには、有害物質処理槽2aの内部に内燃機関や焼却炉(A)から排出された気体を導入するパイプAPが接続されている。
排出孔2eは、有害物質処理槽2aの上部領域2bに設けられており、この有害物質処理槽2a内の液体S中を通過して有害物質が除去された気体を外部へと排出するパイプBPが接続されている。
また、本実施例において有害物質処理槽2a中に収容される前記液体Sは、有害物質処理槽2aの上部領域2bに空間を残すように満たされている。
パイプAPは、有害物質処理槽2a外部から、導入孔2dを介して有害物質処理槽2aの内部の下部領域2c内に挿入され、その下部領域2cにおいて、有害物質処理槽2aの底面を覆うように形成された延設部PEを備えている。
そして、その延設部PEには、多数の微細な孔が形成されている。このように形成すれば、液体Sの最深部で、気体が多数の孔から微細な泡Hになって液体Sに放出される。このとき、大きな泡よりも微細な泡Hの方が、液体Sに含有する微生物と泡Hとの接触が活発であるので、気体の処理が促進されるため好ましい。
また、このパイプAPは、前記下部領域2c内に複数本備えることも可能である。
さらに本実施例では、パイプAPをストレートな管状をもって形成しているが、スパイラル状に前記下部領域2c内に備えることも可能である。
なお、パイプAPは、本実施例で採用した形態に限定解釈されるものではなく、例えば導入孔2dに単に外部から緊密に嵌め込まれる形態などであってもよく、本発明の範囲内で設計変更可能である。
そして、前記液体S中に放出された気体は、液体Sが含有する微生物によって、気体中の一酸化炭素と二酸化炭素が除去処理されるとともに、粒子状物質が気体から分離処理されて、液体S中に取り込まれるようにして、有害物質処理槽2aの底部に沈殿する(有害物質処理工程B)。すなわち、有害物質処理工程Bで処理され、液体S中を通過し、有害物質処理槽2aの上部領域2bに一旦貯溜された気体は、一酸化炭素と二酸化炭素と、粒子状物質が除去されている。
従って、上部領域2bからパイプBPを通って外部へと排出(F)される気体は、上述した通り有害物質が除去されたクリーンな気体である。
本実施例では、一次工程Bと二次工程Dを備えている。すなわち、内燃機関や焼却炉(A)から排出された一酸化炭素、二酸化炭素、粒子状物質などの有害物質を含んだ気体は、一次工程Bに導入されて有害物質の除去処理が施され、さらに、前記一次工程によって除去され得なかった残留有害物質が二次工程Dで除去処理された後に外部に排出(F)される方法を採用している。
この二次工程Dでは、一次工程Bにて除去しきれなかった一酸化炭素や二酸化炭素などの有害物質が残留していた場合、その一酸化炭素や二酸化炭素をさらに除去する。従って、本実施例であっても、実施例1と同様に一次工程Bにて除去処理した段階で有害物質が全て除去し得る場合もある。
なお、本実施例の一次工程Bは、前記実施例1で説明した有害物質処理工程Bと同一内容による工程であるため本実施例ではその説明を省略する。従って、ここでは、二次工程Dについて説明する。
前記焼成体Lは、セラミックスを主成分とし、これに、少なくとも光合成菌を含む菌体群からなる微生物と、酵母菌を含む菌体群からなる微生物と、乳酸菌を含む菌体群からなる微生物とを含有して構成されている。
また、本実施例で採用する焼成体Lには、気体が通過することが可能な貫通孔が形成されている。このように形成されていれば、気体が焼成体Lに接触する面積が増加するので、微生物による処理が促進されるため好ましい。
これらの微生物は、焼成体Lの表面で、一次工程Bを経た気体と反応することによって、その気体中に含まれている(残留している)一酸化炭素、二酸化炭素などの有害物質が除去処理される。
なお、本実施例の一次工程Bの処理装置は、前記実施例1で説明した有害物質処理工程Bの処理装置と同じ構成であるので、ここでは、一次工程Bの処理装置の説明を省略し、二次工程Dの処理装置の構成を中心に説明する。なお、前記実施例1で説明した有害物質処理槽2aは、本実施例では一次工程処理槽2aと称する。
導入孔4dは、二次工程処理槽4aの下部領域4cに設けられており、この導入孔4dには、二次工程処理槽4aの内部に有害物質処理槽2aからの気体を導入するパイプBPが接続されている。
排出孔4eは、二次工程処理槽4aの上部領域4bに設けられており、この二次工程処理槽4a内の焼成体Lによって有害物質が除去された気体を外部へと排出するパイプDPが接続されている。
また、焼成体Lの貫通穴は、穴が貫通する方向を二次工程処理槽4aの気体が流れる方向、すなわち、本実施例では上下方向に合わせて配置される。これにより、気体が焼成体Lの貫通穴を通過することができる。
そして、二次工程処理が完了した気体は、二次工程処理槽4aのパイプDPから二次工程処理槽4aの外部へと排出される。
従って、下部領域4bからパイプDPを通って外部へと排出(F)される気体は、上述した通り有害物質が除去されたクリーンな気体である。
本実施例では、一次工程Bと二次工程Dに加えて、気体中に残留する有害物質をさらに除去する残留有害物質除去工程Cを備えている。すなわち、内燃機関や焼却炉(A)の気体は、一次工程Bで一酸化炭素や二酸化炭素、あるいは粒子状物質などの有害物質が除去処理され、さらに、一次工程Bで気体中から除去しきれなかった一酸化炭素や二酸化炭素などの残留有害物質が二次工程Dで除去処理され、そしてさらに、その二次工程Dを経ても気体中から除去しきれなかった粒子状物質などの残留有害物質が残留有害物質除去工程Cで除去処理された後に外部に排出(F)される方法を採用している。
この残留有害物質除去工程Cでは、一次工程Bにて除去しきれなかった粒子状物質など有害物質が残留していた場合、その粒子状物質をさらに除去する。従って、本実施例であっても、実施例1と同様に一次工程Bにて除去処理した段階で有害物質が全て除去し得る場合もある。
なお、本実施例の一次工程Bは、前記実施例1で説明した有害物質処理工程Bによる工程と同一内容であり、本実施例の二次工程Dは、前記実施例2で説明した工程と同一内容なので、ここでは、一次工程Bと二次工程Dの説明を省略し、残留有害物質除去工程Cの構成を中心に説明する。
残留有害物質除去工程Cでは、残留有害物質除去手段Jに、二次工程Dを経た気体を反応させて、気体中に残留している粒子状物質を取り出すことにより、気体の粒子状物質を除去する処理を行なう。
なお、本実施例は、一次工程Bの処理装置および二次工程Dの処理装置の後に残留有害物質除去工程Cの処理装置を備える構成であり、その一次工程Bの処理装置および二次工程Dの処理装置は、前記実施例2で説明したので、ここでは残留有害物質除去工程Cの処理装置の構成を中心に説明する。
導入孔3dは、残留有害物質除去槽3aの下部領域3cに設けられており、この導入孔3dには、残留有害物質除去槽3aの内部に二次工程処理槽4aからの気体を導入するパイプDPが接続されている。
排出孔3eは、残留有害物質除去槽3aの上部領域3bに設けられており、この残留有害物質除去槽3a内の残留有害物質除去手段Jによって有害物質が除去された気体を外部へと排出するパイプCPが接続されている。
本実施例の残留有害物質除去手段Jは、気体が通過することが可能な内部空間を備え、該空間を外部に備えた電源Kで電荷することによって、前記残留有害物質除去手段Jの内部空間内にマイナスイオンを発生させる。このとき、マイナスイオンにより、プラス帯電している粒子状物質が吸着されて気体から取り出される。
そして、残留有害物質除去工程処理が完了した気体は、残留有害物質除去槽3aのパイプCPから残留有害物質除去槽3aの外部へと排出される。
従って、上部領域3bからパイプCPを通って外部へと排出(F)される気体は、上述した通り有害物質が除去されたクリーンな気体である。
この場合であっても、上記実施例3と同様の効果を得ることができる。
各工程による処理装置の構成および作用効果は、前述した請求項1乃至請求項3と同様なのでその説明を省略する。
この場合であっても、上記実施例2と同様の効果を得ることができる。
微生物を含有した液体Sと微生物を含有した焼成体Lによる同時処理工程(G)は、有害物質処理槽2aの内部で処理される。
すなわち、本実施例の処理装置は、上述した実施例2の一次工程Bで用いられる液体Sを収容した有害物質処理槽2a内に、二次工程Dで用いられる焼成体Lを配置して構成されている。
この場合、有害物質処理槽2aの下部領域2cに設けた導入孔2dには、有害物質処理槽2aの内部に内燃機関や焼却炉(A)からの排気を導入するパイプAPが接続され、さらに、有害物質処理槽2aの上部領域2bに設けた排出孔2eには、同時処理工程(G)による処理後の気体を排出するパイプBPが備えられている。
これにより、同時処理工程(G)の処理において、気体は、微生物を含有した液体Sと、微生物を含有した焼成物Lの両方で同時に処理される。その他の構成および作用効果は、前述した実施例2と同様なのでその説明を省略する。
この場合の処理装置では、有害物質処理槽2aの他に、実施例3で説明した残留有害物質除去槽3aを備えれば良い。
また、本実施例による同時処理工程(G)は、上述した実施例2乃至実施例4の一次工程(B)と置き換えられても良い。この場合には、焼成体Lによる処理が重複して行なわれるので、さらに、有害物質の除去される効率が向上する。
本実施例では、一例として、前記実施例4で説明した処理工程に加えて、さらに、最終処理として消臭工程Eを備えている(図6(a)のフロー図参照)。すなわち、内燃機関や焼却炉(A)の気体は、一次工程Bで一酸化炭素や二酸化炭素、あるいは粒子状物質などの有害物質が除去処理され、さらに、一次工程Bで気体中から除去しきれなかった粒子状物質などの残留有害物質が残留有害物質除去工程Cで除去処理され、そしてさらに、一次工程Bで気体中から除去しきれなかった一酸化炭素や二酸化炭素などの残留有害物質が二次工程Dで除去処理され、さらに、脱臭工程Eで脱臭処理された後に外部に排出(F)される方法を採用している。
なお、本実施例の一次工程Bは、前記実施例1で説明した有害物質処理工程Bによる工程と同一内容であり、本実施例の残留有害物質除去工程Cは、前記実施例3で説明した残留有害物質除去工程Cによる工程と同一内容であり、本実施例の二次工程Dは、前記実施例2で説明した工程と同一内容なので、ここでは、一次工程Bと残留有害物質除去工程Cと二次工程Dの説明を省略し、脱臭工程Eの構成を中心に説明する。
脱臭工程Eでは、脱臭手段Mに、残留有害物質除去工程Cを経た気体を反応させて、気体中の不快な臭いの脱臭処理行なう。
本実施例による有害物質除去方法に使用される処理装置の一構成例の概略を説明する(図6(b))。
なお、本実施例は、一次工程Bの処理装置および残留有害物質除去工程Cおよび二次工程Dの処理装置の後に脱臭工程Eの処理装置を備える構成であり、その一次工程Bの処理装置および二次工程Dの処理装置は前記実施例2で説明し、残留有害物質除去工程Cの処理装置は前記実施例3で説明したので、ここでは脱臭工程Eの処理装置の構成を中心に説明する。
導入孔5dは、脱臭工程処理槽5aの下部領域5cに設けられており、この導入孔5dには、脱臭工程処理槽5aの内部に二次工程処理槽4aからの気体を導入するパイプDPが接続されている。
排出孔5eは、脱臭工程処理槽5aの上部領域5bに設けられており、この脱臭工程処理槽5a内の脱臭手段Mによって不快な臭いが脱臭された気体を外部へと排出するパイプEPが接続されている。
本実施例の脱臭手段Mは、気体が通過することが可能な内部空間を備え、該空間を気体が通過する際に気体中の不快な臭いを脱臭処理する。脱臭手段Mとして、本実施例では、活性炭のような多孔質体の微細な孔に臭いの分子が吸着されて脱臭される手段が採用される。
そして、脱臭処理工程処理が完了した気体は、脱臭工程処理槽5aのパイプEPから脱臭工程処理槽5aの外部へと排出される。
従って、上部領域5bからパイプEPを通って外部へと排出(F)される気体は、上述した通り有害物質が除去されたクリーンな気体である。
さらに、複数の処理装置が一つの処理槽にまとめて構成されていても良い。例えば、実施例2の一次工程処理槽2aの上部領域2bの空間に、二次処理工程Dの焼成体Lが配されていても良い。
