Description
物質移動とは、吸着媒体を使用して気流から気相汚染物質を除去するときに使用される用語である。容量ではなく、むしろMTZの長さが、媒体の効率と寿命を決定するが、MTZの長さは業界では通常使用されない。というのも、これは測定が難しく、時間がかかるからである。
気相除去媒体の使用における別の因子として、空気流または圧力降下に対する抵抗がある。空気清浄は、しばしば、建物の暖房、冷房、換気(HVAC)システムで使用される。多くのHVACシステムには、追加の圧力降下に十分なほどの強力なファンがなく、既存のシステムにおいての空気清浄の適用が制限されている。ファンが十分に大きく、かつ/または元の設計で空気清浄の必要性が考慮されていた場合でも、大きな圧力低下は、エネルギーと運用コストを増加させる可能性がある。
・ペレットトレイモジュールと比較して20~70%低い圧力損失。
・ペレットトレイシステムの推定された半分の重量。
・従来のペレット化されたカーボンベッドよりも、最大6倍の速度での、高速かつ効果的な媒体接触。
・吸着剤は完全にアクセス可能であり、より短いMTZの長さ、より高い効率、および媒体の完全利用を可能にする。
・後濾過の必要性を排除した、安定した構造を有するダストフリーの媒体。
図2A~図2E、図3Aおよび図3B、図4A~図4D、図5A、図5Bに示すように、エアフィルタモジュール200,400は、通過する空気を濾過する空気ダクトまたは通路90内に、それ自体取り外し可能に配設してもよいエアフィルタシステム300(本明細書では一般に「エアフィルタ」と呼ばれる)内に取り外し可能に配設されてもよい。濾過される空気流へのフィルタ媒体214,414の露出を最大にし、圧力降下を最小にするために、フィルタモジュール200,400を空気流に対して傾斜させてもよく、この場合、フィルタモジュールの前面(空気の流れに面する)からフィルタモジュールの背面までの空気流のための最短経路は、断面線2B,2C,2D,2E-2B,2C,2D,2Eとして示される線に沿って定義されることが理解され、この線によって、本出願全体で説明されている、チャネルを通過する空気流経路が、より長いチャネルと対比されている。
)630および後縁(trailing edge)640を有して形成されてもよい。
フィルタ媒体214,414は、本明細書に記載されるものを含む、任意の効果的な媒体であればよい。フィルタ媒体214,414は、50重量%のココナッツまたは木材活性炭で作られ得る活性炭紙媒体であってもよい(IAQ用途の場合、ハニカム構造体は3060重量%の炭素である)。ココナッツカーボンは、ハニカム構造体に使用され得る木材ベースのカーボンと比較して、微小孔の体積が大きいので、VOCの吸着に使用可能である。活性炭紙の製造方法により、ターゲット特異的チャレンジガスへの添加剤に対する、またはゼオライト、モレキュラーシーブ、MOFなどの代替吸着剤の追加についての柔軟性が得られる。対照的に、ハニカム構造体は多くの吸着剤を使用して作るのが難しく、バインダー系と互換性のある添加剤に制約される。
図7Aおよび図7Bは、支持ビーム720を含むことが可能である構造上に支持されたフィルタ媒体710を有するフィルタモジュール700を示す。フィルタ媒体710は、ビーム720上に取り付けられた個々のシート部材710を含む。スペーサ730は、媒体710間に一貫した間隔を保証し、一貫した断面の空気チャネル740を形成するのに役立つ。
