Description
建屋内部の酸素濃度は徐々に低下し、可燃性ガスが燃焼できない濃度に達する。この時の酸素濃度を「限界酸素濃度」という。この値は可燃性ガスによって固有の値を持ち、水素の場合5.0%、メタンでは12.1%である。
上式より空気中の酸素を限界酸素濃度a2まで低下させる窒素量 Vは
例えば建屋容積=7,000m3、目標の酸素濃度(=水素の限界酸素濃度)=5%を
即ち容積7,000m3の建屋内の酸素を窒素で置換して燃焼を継続できない酸素濃度まで低減させるには可燃性ガスを水素と仮定した場合、容量で約10,000m3の窒素が必要である。

Claims (5)
- 導管を用いた水素インフラが存在する広域な地域において使用される窒素製造所の窒素供給設備であって窒素製造所から導管を用いて水素導管中に窒素を混合して水素・窒素の混合ガスとし、更に供給先の人口密度により供給地域を人口過疎地域、人口密集地域及び人口平均地域の三地域に分類して窒素製造所、窒素導管、水素・窒素混合器、水素・窒素分離器及び水素精製器を用いて上記の地域毎に水素・窒素の混合ガス中の水素と窒素の混合比率が異なる構成の供給方式を定め、各々の地域に窒素を水素・窒素の混合ガス又は窒素単独ガスとして供給することを特徴とする窒素インフラ システム。
- 前記窒素製造所の窒素供給設備が窒素製造設備又は窒素リサイクル設備のいずれかあるいはその両方を備え、水素・窒素混合器及び水素・窒素分離器を使用してガス中の水素と窒素の混合比率を任意の組成に調整して水素・窒素の混合ガス又は窒素単独ガスとし、前記の地域区分に従って地域を三地域に分類しこれ等の三地域を組み合わせた供給先に導管を用いて窒素を水素・窒素の混合ガス又は窒素単独ガスとして供給することを特徴とする請求項1に記載の窒素インフラシステム。
- 前記窒素インフラの水素・窒素分離器が水素分子と窒素分子の大きさの差を利用した膜方式又は水素分子と窒素分子の固体吸着物質への吸着力の差を利用した吸着方式であって、水素・窒素の混合ガス中の水素及び窒素濃度を測定するに当たり両ガスの熱伝導度又は電気伝導度の差を利用して水素・窒素混合ガス中の水素と窒素の濃度を測定し、これ等の濃度と水素及び窒素の流量を組み合わせて水素・窒素の混合比率を任意に調節できることを特徴とする請求項1に記載の窒素インフラ システム。
- 前記窒素インフラが水素インフラの防災設備として使用されることに加え窒素インフラの窒素供給設備から新たに配管を使用して窒素を分岐し、前記、請求項1に記載の三地域に存在する物流倉庫、美術館等の密閉型建屋における災害の発生時又は発生予想時に建屋内に窒素ガスを吹き込むことにより建屋内の酸素濃度を低下させて建屋の火災・爆発災害を防ぐ防消火設備として活用することを特徴とする請求項1に記載の窒素インフラシステム。
- 前記窒素インフラの窒素供給設備が同設備が存在する地域の空気分離装置から分離された窒素を液化窒素とし、これを液化窒素ローリ車を用いて窒素供給設備まで輸送して窒素供給のためのバックアップとして使用することを特徴とする請求項1に記載の窒素インフラシステム。
