Abstract
Description
ここで、排煙脱硫装置は、湿式方式の石灰石‐石膏法が主流を占めており、中でも石灰石スラリーをノズルからスプレ方式で噴霧して排ガスと気液接触させるスプレ方式は信頼性が高く、石灰石スラリーの塔内への噴霧方法として多く採用されている(特許文献1)。
このSO3はまだガス体である。
このように、本発明によれば、熱交換器16で、排ガスの温度を酸露点以下とし、この酸露点以下となった前記排ガス中のSO3を、煤塵にまぶされた硫酸液滴として凝縮させるようにしている。
その後、浄化ガス12Dは誘引ファンF2により、煙突18に送られる。
また、空気20と排ガス12Bの熱交換をする際に、熱媒体として水を用いるようにしてもよい。
この結果、発電所全体のエネルギー効率の向上を図ることができる。
さらに、ガス中硫黄分を除去する機構が凝縮によるので、中和反応の媒介となる水分が不要となる。
本発明では、空気を予熱する際に、酸露点以下の100℃まで降下させることができるので、従来よりも50℃分エネルギー交換効率が向上することとなる。
この結果、発電所のエネルギー効率を0.5%以上上昇させることが可能となる。
図2は、本発明の実施例2に係る排ガス処理システムの概略図である。
図2に示すように、本実施例の排ガス処理システム10Bは、SO2・SO3転換触媒部15と熱交換器16との間の煙道13中に、粉体である石灰石41を導入する粉体供給手段42が設けられている。
この場合には、熱交換器16での煤塵31による硫酸液滴30の被覆が完全とならない場合がある。
このため、石灰石41を導入して、煤塵31と石灰石41とにより硫酸液滴30の周囲を被覆してサラサラ状態で、集塵機17に送って、捕集するようにしている。
図3は、本発明の実施例3に係る排ガス処理システムの概略図である。
図3に示すように、本実施例の排ガス処理システム10Cは、実施例1において、さらに脱硝装置14とSO2・SO3転換触媒部15との間に、空気予熱器19を介装するようにしている。
本実施例では、空気予熱器19により高温排ガス12A1を150℃の低温排ガス12A2としているので、SO2・SO3転換触媒部15に導入される排ガス温度は、実施例1よりも低くなる。よって、本実施例では、SO2・SO3転換触媒部15で用いるSO2・SO3転換触媒は、低温(150℃)での触媒活性が高い触媒を用いるようにしている。
