Abstract
【解決手段】流体から中立浮力粒子を分離するシステムであって、中立浮力粒子を含む流体の少なくとも一部分を受け取る入口と、中立浮力粒子がチャネルの中心からずれた管状帯で流れるように流体が流れる渦巻き状チャネルと、管状帯が流れる流体のための第1の出口と、残りの流体のための第2の出口と、を有するシステムである。
【選択図】図3a
Description
2)サイズで分離するように拡張するには、流れパラメータを単調な範囲の粒子サイズに調整し、渦巻き状チャネルに沿って連続的に捕捉チャネルを提供するだけでよい。
3)粒子サイズ範囲カットオフが小さくなるようにそれぞれ適合された、いくつかの渦巻き構造をカスケード接続することができる。
4)この装置を他の下流プロセスと直列統合し且つ独立用途として働くように単純に修正できる設計。
5)ろ過能力の動的粒子サイズ範囲が大きいため、高処理量の大規模用途と極小細規模のラボ・オン・チップ用途の両方に適する。
6)処理量を高めるためにモジュールユニットの並列化を実現できる。
7)このメンブレンを使用しない装置は、高処理量と低コストの望ましい組み合わせを有し、本質的に大規模用途から小規模用途での予備的ろ過に適する。
8)メンブレンを使用せずに中立浮力粒子を迅速に流体分離するための渦巻き構造のための設計技術が提供される。
9)帯を両側から首尾良く圧縮するために二重入れ子渦巻き状チャネルを実施することができる。
10)短い長さの方式に基づいて極めて拡大可能性の高い実装が実現される。
11)従来の水処理の凝集および沈殿段階をなくすことができる。
12)意図された構造は、IC製造の再生材料、冷却塔水、MBR(膜バイオリアクタ)、RO(逆浸透)の前処理を含む他の水用途に使用することができる。
