Description
Claims (1)
- 【特許請求の範囲】 1. 煙道ガスのような熱処理ガスから二酸化硫黄のようなガス状の汚染物質 を分離する方法であって、熱処理ガスは、ガス状の汚染物質を分離可能な塵に変 えるため、ガス状の汚染物質との間で反応性を有する粒状の吸収材が湿った状態 で熱処理ガスに導入される接触反応器(10)に通され、さらに熱処理ガスは、 その内部で熱処理ガスから塵が分離されるとともに浄化処理済みガスが排出され る塵分離器(5)に通され、この塵分離器(5)内にて分離された塵の一部は、 その内部で混合がなされるとともに湿潤化のために水が供給されるミキサー(1 1)に通され、さらにこの塵の一部は、新たな吸収材の追加分とともに熱処理ガ スに導入されることにより吸収材として再循環する方法において、生石灰が新た な吸収材として追加され、かつ塵分離器(5)内にて分離された塵の大半はミキ サー(11)に対して略連続的な流れとして供給および排出され、この塵は、ミ キサー(11)内における湿った状態での生石灰の総滞留時間が、生石灰とミキ サーに供給される水とが略完全に反応し、かつ生石灰から消石灰が形成されるの に十分な時間となるよう、ミキサー内で長時間にわたって留まり、かつ多数回に わたって再循環することを特徴とする方法。 2. 生石灰の形態をなす新たな吸収材は、ミキサー(11)に供給されるこ とを特徴とする請求項1記載の方法。 3. 生石灰の形態をなす新たな吸収材は、塵分離器(5)内にて分離されミ キサー(11)に供給される塵の一部に追加されることを特徴とする請求項1記 載の方法。 4. 生石灰の形態をなす新たな吸収材は、接触反応器(10)内の煙道ガス 内に直接導入されることを特徴とする請求項1記載の方法。 5. 混合された塵を流体化させるために、ミキサー(11)に空気流が供給 されることを特徴とする請求項1乃至4のいずれか記載の方法。
