Abstract
Description
本願は2020年3月24日に出願の米国仮特許出願番号第62/993,871号の恩典を主張する。先願の開示は本願の開示の一部とみなされる(かつ参照により本願の開示に組み入れられる)。
本開示は、移動する液体キャリア中にナノバブルを発生させることに関する。
多量の液体媒体(例えば、水塊)に気体(例えば、空気)を供給して液体媒体中で所望の気体飽和度を得るためのポンプまたはブロワシステムなどの様々なシステムが用いられてきた。水の供給源に酸素を供給することはその水質を改善し、水の供給源に存在する酸素を利用する様々な生物に利益をもたらし得る。
一つ目の概略的な局面では、河川、水流、クリーク、小川、細流、川、海峡、運河、水路、三角洲、入江、細溝、導水路、カルーセル、支流、パイプなどの移動する液体キャリア中にナノバブルを生成するための装置が記載される。装置は、液体キャリアがそれを通って流れることのできる、第1端から第2端まで軸方向に延在する開口を有する導管を含む。導管は、導管の内面に配置された内面と、液体キャリアが導管を通って流れる際に液体キャリアと接触するように構成された外面とを有する気体拡散器をさらに含む。気体拡散器は、気体源から気体を受け取り、気体を拡散器の外面まで運ぶように構成された複数の細孔を含む。いくつかの態様では、装置は、導管内で互いに平行に配置された複数の拡散器を含む。拡散器はフレームに取り付けられ得、翻ってフレームは導管の1つまたは複数の壁に取り付けられる。
図1Aは、移動する液体キャリアに気体を注入するために実装し得る装置100の概略図である。装置100は、外側ハウジング104内に導管101、漏斗151a、任意の第2漏斗151b、および気体拡散器160を含む。導管101は、第1端102aから第2端102bまで軸方向に延在する開口を規定する。漏斗151aは、第1開放端152a、第2開放端152b、および第1開放端152aから第2開放端152bまで延在する壁153を含む。気体拡散器160は、導管101の内面105に沿って配置される。気体拡散器は、吸気口106を介して気体源150から受け取った気体が外側ハウジング104の密封空洞108に流入し、気体拡散器160を通過して導管101に入るように、導管によって規定される開口と一直線に整列されるかまたはそれを覆うように配置される。導管101、漏斗151a、および気体拡散器160は、装置100の動作時には互いに対して静止したままであるように構成される。いくつかの態様では、装置100は漏斗(例えば、導管の第1端102aにある漏斗151a)を1つだけ含み、任意である第2漏斗(例えば、漏斗151b)は含まない。
