Description
図1は本発明のシステム全体を示す図である。図中、1は粉砕機、2は炭化炉、3はガス化炉であり、廃棄物が粉砕機1に投入され(矢印A)、得られた粉砕物が炭化炉2に投入され(矢印B)、炭化炉2内に空気を導入して(矢印C)燃焼排ガス5と炭化物を得る。そしてこの炭化物はガス化炉3に投入され(矢印D)、かつ水蒸気7がガス化炉3に投入される(矢印E)。そして、炭化物と水蒸気の接触下に、反応熱源としてガス化炉3に燃焼排ガス5が導入され(矢印F)、主として吸熱反応によってガス化される。符号11は蒸気ボイラー、12は熱交換器である。
一方、燃焼排ガス5はその後ガス化炉から排出され、その余熱を各種の熱源として利用され(矢印H)、更には、ガス化炉3から排出されるスラグ10からは資源再利用が図られる(矢印I)。
図1にあって、21は廃棄物粉砕機1中に配置した粉砕カッター、22は排出スクリュー、23はこれに連動する斜めに配置された移送スクリューである。粉砕混合物の排出・移送方式は適宜選択できるが、密閉性を考慮するとスクリュー方式がよい。
この際、廃材中に飛散性或いは非飛散性アスベストが存在することもあるが、本発明にあっては、融解剤(例えばアルカリ系化合物等のアルカリ化合物)をこれらとともに投入し、これによってアスベストは減容固化非飛散処理され安全・安定な性状に溶融無害化してしまうこととなる。
図2は、本発明の特徴である自燃式(流下式連続)炭化炉、即ち自己燃焼熱(部分酸化反応熱)により炭化を行う炭化炉2の基本構造を示す。炭化炉2は図示はしないが適当な耐火断熱材にて覆われている。符号31は炭化炉2の円筒内部であり、上部が発生したガスの燃焼部、中部が粉砕物の燃焼部、下部が精錬部である。32は廃棄物粉砕機1にて得られた粉砕混合物の投入口であり、33、34は空気の導入口である。
図3にガス化炉3の基本構造を示す。この図でも図2と同様に耐火断熱材に類する記載は省略している。さて、ガス化炉3は円筒状の反応炉40を中央に配置し、この周囲に熱源室41(反応炉加熱部)が配置されている。反応炉40は炭化炉2にて得られた炭化物を投入するための投入口43と、ガス化された生成ガスの取り出し口44と、スラグ10の排出のためのスクリュー45が備えられる。そして、投入された炭化物と接触させてガスを生成するに必要な蒸気を導入するための蒸気導入口46が備えられている。
本発明は、ガス化剤として水蒸気をガス化炉3内に導入し、炭化物(炭素)と接触反応させて水素を豊富に含んだガスを得るものである。ガス化の反応を例に取れば、吸熱反応によってC+H2O→H2+CO、シフト反応によってH2O+CO→H2+CO2が得られ、実機テストにあっては、H2:60%、CO:20%、CO2:20%の水性ガスが効率よく得られた。
アスベストを無害化するには、できる限り低温でアスベストを融解させる融解剤を見つけ出すことであり、アルカリ化合物に着目してこれを融解剤としたものである。アスベストは、粉末状、半ナマ状、スラリー状のいずれの形態のものでもよく、800℃程度で加熱処理してなるものである。これによって、アスベストを確実に分解することができ、アスベストの繊維形態の消滅、結晶構造の崩壊等を引き起こして無害化されるものである。融解剤としては、たとえばフッ化カルシウム、炭酸カルシウム、酸化カルシウム、珪酸ナトリウム、水酸化ナトリウム等、およびこれらの組み合わせが挙げられる。
図2に示す炭化炉は、目的によっては更に変更が可能である。即ち、図2に示す炭化炉においては、得られる炭化物の容量が比較的大きいが、これは、炭化物として不適当な燃焼滓が全て炭化物と一体となって取り出されるからである。このため、次工程のガス化炉3のボリュームが必要以上に大きくなるという問題があった。
下炉2Bにあって、54は炭化物取出口であり、この炭化物取出口54から取り出された炭化物が、次工程のガス化炉3に導かれる。
以上、本発明のシステム及びその装置について説明したが、システム全体を一つの処理装置として一体に設置することがよいが、これらを車載型、即ちトレーラーやコンテナ等に納めて移動可能な装置とすることも可能であり、自燃型・エネルギー自給型という特徴を生かし、国内外での被災地等での瓦礫処理・電力供給設備として貢献できることとなる。
従って、不幸にもおきた地震災害による瓦礫の処理に供されることは勿論、他の場所での処理、例えば台風による流木の処理等に広く利用可能であり、その利用範囲は広い。
