特開2018-84042 「窒素インフラ システム」
この特許には導管を使用して広域な範囲に水素インフラを構築すると共に同時並行して「導管を使用する窒素インフラの構築」が提言されている。同特許には窒素を水素ステーションの安全対策に使用すると共に、容積が数万m3クラスの超大型の物流倉庫での発災時に窒素を消火用として活用する事例が紹介されている。
例えば建屋容積A=1,000m3、a1=21.0、a2=5.0を代入すれば、窒素量V=1,430m3となる。即ち容積Am3の建屋内の空気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、容量で建屋容量Aの約1.43倍の窒素が必要である。

Claims (4)
- 戸建て建屋が火災に遭遇した際に使用する防消火設備であって、建屋の発災に備え予め消火対象となる建屋の周囲を容易に囲うことが可能な組み立て式のフレームと高熱に耐える耐火布を準備し、上記の建屋で火災が発生した際にこれ等を現地まで運搬し、建屋の周囲に開放部を持つ一時的な空間部を設け、別途用意した窒素ガスを同空間部及び建屋内に放出して、建屋の周囲及び建屋内部の酸素濃度を可燃性ガスの燃焼に必要な酸素濃度以下に低下させることにより、火災を消火または防火する機能を有する乾式防消火設備。
- 前記乾式消火設備が消防車により容易に運搬することが可能な移動式であって、現地で任意の形に組み立てた後、窒素ガスを建屋周囲の空間部に放出するための複数の噴射ノズルを有する放出口と建屋内に窒素を吹き込むためのホースによる放出口を装備することを特徴とする請求項1に記載の乾式防消火設備。
- 前記 戸建て建屋の外周に臨時の空間部を設ける際に使用するフレームと耐火布については、敷設する空間部の形状に従って上部に空間ができるよう立体型に敷設できる構造とし、かつその立体型の上部面積が下部面積に比べて小さくなるように製作されたフレームと耐火布を使用することを特徴とする請求1に記載の乾式防消火設備。
- 前記戸建ての建屋の乾式防消火設備向けの窒素の供給方法については当該建屋が存在する地域の窒素供給所から液化窒素ローリ車を使用して液化窒素を当該建屋まで運搬し、これを気化器を使用して窒素ガスとして上記の空間部及び建屋内に向けて放出することを特徴とする請求項1に記載の乾式防消火設備。
