Description
図1は、本発明に係る脱気処理に用いる脱気装置用充填材の改質処理方法での第1の実施形態に用いる処理装置を示す概略図である。
また、本発明に係る脱気処理に用いる脱気装置用充填材の改質処理方法での第2の実施形態は、電気分解ガス発生装置での高濃度オゾンガス発生のための手段が異なるだけで、その他の構成は第1の実施形態と同一の処理装置を用いて行なうものである
実施例1では、図1に示した構成の装置を用いて測定を行った。
まず、脱気装置用充填材の処理槽11(水槽寸法:奥行850mm×幅5900mm×高さ650mm(有効水深500mm))内に、脱気装置用充填材(日鉄化工機株式会社製、商品名:テラレット)を1.5m3(100L/袋×15袋)投入して、有効水深500mmまで純水を注入した。SUS−316製オゾン水循環ポンプ13(1kW)で3m3/分づつ循環しながら、電気分解ガス発生装置で陽極側に純水を供給して得られたオゾン濃度10%の発生ガスを1.8L/分でオゾンガス散気管12(口径:25A、長さ:2m、2本)から処理槽11内に散気、溶解した。処理槽11内のオゾン水のオゾン濃度は平均で10ppmであることを確認して、このまま4日間(136時間)処理した後、処理槽11から取り出し自然乾燥した。なお、テラレットの材質としては、ポリプロピレン(PP)、ポリエチレン(PE)、ポリ塩化ビニール(PVC)の3種類について同様に処理を行った。
実施例2では、図2に示した構成の装置を用いて測定を行った。
本実施例においては、電気分解ガス発生装置において高濃度オゾンガス発生のための手段が異なるだけで、その他の構成は実施例1と同じ装置を用いた。
Claims (3)
- 脱気装置用充填材を用いた脱気方法において、脱気を行う前に予め脱気装置用充填材を構成する樹脂とオゾン水とを接触させ、前記接触で得られた脱気装置用充填剤を用いて脱気を行うことを特徴とする脱気方法。
- 前記オゾン水中のオゾン濃度が、10〜70mg/Lであることを特徴とする請求項1記載の脱気方法。
- 前記樹脂が、ポリエチレン、ポリプロピレン及びポリ塩化ビニールから選ばれた少なくとも1種を含む樹脂であることを特徴とする請求項1又は2記載の脱気方法。
