Description
また上記構成によれば、第2流通路の鉛直方向下部に液体排出口が設けられているので、ガス中に液体成分、例えば水が含まれていた場合に、第2流通路内で凝集した液体を流路内で滞留させることなく外部に排出することが可能となる。
また上記構造によれば、拡散構造が第1のガスが第2のガスの流れに対して拡散させるため、第1のガスと第2のガスとが衝突し乱流が発生して、希釈性能が向上することが期待できる。特に拡散構造は、第2流通路内におけるガスの流通方向とは異なる方向で第2流通路内に第1のガスを流出させる孔構造となっているので、第1のガスと第2のガスとの混合度が向上し、均一にガス濃度を低下させることが可能となる。例えば第1のガスまたは第2のガスのいずれか一方が可燃性のガスである場合、可燃性ガスの濃度を均一に下げ、外部に排出することができる。
また上記構造によれば、第1のガスの流通方向下流ほど単位面積当たりの孔合計開口面積が大きくなるように設けられているところ、第1流通路の上流側ほど第1のガスの濃度が高く下流側ほど濃度が低くなるため、拡散構造から流出した第1のガスが第2のガスと混合された場合、混合ガス中の第1のガスの濃度がいずれの箇所でも均一化にすることができ、第2流通路内における第1のガスの濃度の偏りを抑制することができる。
そして上記構造によれば、攪拌部材があるため、第2流通路内に生ずる気流にさらに局所的な乱流が多数発生し、さらに均一の第1のガスと第2のガスとを混合することができる。
本発明の実施形態1は、電気自動車に搭載する燃料電池システムに用いるために適する希釈器に本発明のガス処理装置を適用したものである。特に、希釈すべき水素ガスを希釈媒体である空気の供給パイプの周辺において乱流を発生させ混合するガス処理装置に関する。以下の実施形態は本発明の一形態に過ぎず、本発明はこれに限定されずに適用可能である。便宜上、本発明にいう第1のガスとして水素ガスを例示し、第2のガスとして空気を例示する。
2H++2e―+(1/2)O2 → H2O …(2)
H2+(1/2)O2 → H2O …(3)
式(1)の反応を生じさせるために、水素タンク200は、内部に水素吸蔵合金を備えている。水素吸蔵合金は、加熱すると吸熱反応を通じて水素を放出し、冷却すると放熱反応を通じて水素を吸蔵するような性質を有している。水素タンク200は、図示しない熱交換システムによって所望の量の水素を放出するように制御可能に構成されている。
本発明の実施形態2は上記実施形態1の希釈器において、さらにガスの混合・希釈を促進するための流通路の構造の変形例に関する。図6に本実施形態2における希釈器の側面図を示す。図6に示すように、本希釈器100bはハウジング101内において、流通路110の一部に屈曲部112を備えている点で特徴がある。その他の構成については上記実施形態1と同様である。
上記実施形態1では空気オフガスの流通路を囲むハウジングに水素オフガスを流入させ流通路の周囲から水素オフガスを供給する構造であったが、本発明の実施形態3では空気オフガスの流通路内部に水素オフガスの流通路を配置した点に特徴がある。
