Claims (2)
- 汚染土壌を加熱浄化処理する一次加熱処理キルンを配設し、一次加熱処理キルンの排気煙道の下流には排ガス中のダストを捕捉する一次集塵機を配設し、一次集塵機の下流には排ガス中の揮発性有機化合物を燃焼分解させる二次加熱処理装置を配設し、二次加熱処理装置の下流には排ガス温度を低下させる冷却塔を配設し、冷却塔の下流には二次集塵機であるバグフィルターを配設し、バグフィルターの入口側の煙道内に消石灰を吹き込む消石灰供給装置を配設する一方、前記一次加熱処理キルンから排出される加熱土壌を一時貯蔵する加熱土壌貯蔵ビンを配設すると共に、加熱土壌貯蔵ビン内の加熱土壌から揮発する揮発分を排気ダクトを介して前記二次加熱処理装置へと導いて燃焼分解するように構成したことを特徴とする汚染土壌の加熱浄化装置。
- バグフィルターを経由して排出される排ガス中の硫黄酸化物および/または塩化水素の濃度を測定する濃度計測器を備え、該濃度計測器の計測値に応じて消石灰供給装置からバグフィルターの入口側の煙道内に供給する消石灰量を調整するように構成したことを特徴とする請求項1記載の汚染土壌の加熱浄化装置。
