Description
ガスの浄化を、ガラス溶融が終わらされるまで中断されないプロセスとして働かせることができる。従来のSCR触媒を用いる場合、触媒の適当な寿命が達成されない。ガラス溶融は、炉の内壁が交換されなければならないまでシャットダウンされず、並びに/もしくは、シャットダウンされ再始動されることができないため、ガラス溶融の実行時間に対応した最小限の寿命を有する触媒が、見つけられなければならず、又は、2つのDENOxシステムの間で切り替えが可能であるように、これら2つのDENOxシステムが構築されなければならないものだった。この手続により、ガラスの製造プロセスはずっとより高価にされたものだった。
湿式洗浄の段階をなくすることのために、このことは、また、浄化された洗浄水の残っている残余物の濃度から環境汚染物質をなくす。
ガラス溶融物内には、ボロンと砒素との化合物のような、特殊な添加物質並びに/もしくは付随物質が、ほぼ1650℃の温度で溶融されている。
Claims (10)
- ガラスの溶融プロセスの排出ガスを浄化するための方法において、
前記ガラスの溶融プロセスの排出ガスは、少なくとも1つの触媒活性の吸着剤及び/又は吸収剤を用いる対向流移動層反応器システム内で、少なくとも2つの段階で唯一の移動層内で汚染成分から解放され、
触媒を損傷する汚染成分の流れの入り口領域にすぐに続く前記対向流移動層の部分又は前記流れの入り口領域にすぐに続く前記対向流移動層の部分に隣接する前記対向流移動層の部分を含む第1の領域に、第1の分離段階が形成され、該第1の分離段階において、少なくとも、ボロン及び/又は砒素化合物を含む触媒を損傷し原料の組成から発生する化合物が、吸着及び/又は吸収により束縛され、前記排出ガスに含まれる粒子状の成分が付着されて除去され、
NOxの触媒による除去が、前記第1の領域の上方の前記対向流移動層の領域である第2の領域に第2の分離段階を形成することによって実行され、前記触媒を損傷しない他の少なくとも幾らかの汚染成分は、この第2の分離段階で吸着及び/又は吸収により除去されることを特徴とする方法。 - プリ浄化段階が、前記対向流移動層反応器システムから上流に設けられていることを特徴とする請求項1に係る方法。
- 前記排出ガスの浄化は、約70℃ないし160℃のガス入口温度で、前記対向流移動層反応器システム内で実行されることを特徴とする請求項1又は2に係る方法。
- 前記ガラスの溶融プロセスの排出ガスは、始めに、1つ以上の段階で、希薄にさせる空気及び/又は水を加えて、50℃ないし120℃の間の温度に冷却され、並びに/若しくは急冷されることを特徴とする請求項1乃至3のいずれか1に係る方法。
- 除去される前記汚染成分は、砒素及び/又はボロンの化合物からなることを特徴とする請求項1乃至4のいずれか1に係る方法。
- 前記第1の分離段階で除去される前記汚染成分は、珪素、カルシウム、ストロンチウム、及び/又はバリウムの化合物を含有することを特徴とする請求項1乃至5のいずれか1に係る方法。
- 80%ないし95%の前記NOxが、アンモニアを加えることにより除去されることを特徴とする請求項1乃至6のいずれか1に係る方法。
- 前記対向流移動層反応器システムでは、前記対向流移動層の下端から吸着剤及び/又は吸収剤が除去され、前記対向流移動層の上端で新しい又は再生成された吸着剤及び/又は吸収剤が補充されるサイクルが、除去される前記排出ガスが受ける、前記対向流移動層の流動深さ又は部分的な深さにわたる流動圧の低下に応じて、もしくは、前記流れが接近する領域で、触媒を損傷させる気体状の成分のために、前記吸着剤及び/又は吸収剤が受ける損傷に応じて、実行されることを特徴とする請求項1乃至7のいずれか1に係る方法。
- 前記吸着剤及び/又は吸収剤は、炭素性の吸着剤及び/又は吸収剤、並びに酸性の汚染成分のための複数の試薬の層が形成された混合物からなることを特徴とする請求項1乃至8のいずれか1に係る方法。
- 前記吸着剤及び/又は吸収剤は、活性炭、及び/又は、無機の成分又は無機の成分と有機の成分若しくは含有物の混合物からなる顆粒であることを特徴とする請求項1乃至9のいずれか1に係る方法。
