Title (EN) MONOLITHIC SEPARATION MEMBRANE STRUCTURE
(FR) STRUCTURE DE MEMBRANE DE SÉPARATION MONOLITHIQUE
(JA) モノリス型分離膜構造体
Abstract:
(EN) A porous support body (10) has a plurality of filtration cells (C1) opening at both end surfaces (S1, S2), a plurality of water collecting cells (C2) closed on both end surfaces (S1, S2), and a plurality of discharge flow paths (C3) running through the plurality of water collecting cells (C2) and opening to an outer peripheral surface (S3). The porous support body (10) includes a monolithic base material (11) forming the outer peripheral surface (S3). A separation membrane (40) is formed on the inside surfaces of the plurality of filtration cells (C1). The plurality of filtration cells (C1) includes first and second filtration cells (C11, C12) that are adjacent to each other. The plurality of water collecting cells (C2) include water collecting cells (C2) adjacent to the first filtration cells (C11) and separated from the second filtration cells (C12). A first partition wall thickness (L1) for base material (11) between the first filtration cells (C11) and the water collecting cells (C2) is thicker than a second partition wall thickness (L2) for the base material (11) between the first filtration cells (C11) and the second filtration cells (C12).
(FR) L'invention concerne un corps de support poreux (10) qui comporte une pluralité de cellules de filtration (C1) s'ouvrant au niveau des deux surfaces d'extrémité (S1, S2), une pluralité de cellules de collecte d'eau (C2) fermées sur les deux surfaces d'extrémité (S1, S2), et une pluralité de trajets d'écoulement d'évacuation (C3) s'étendant à travers la pluralité de cellules de collecte d'eau (C2) et s'ouvrant sur une surface périphérique externe (S3). Le corps de support poreux (10) comprend un matériau de base monolithique (11) formant la surface périphérique externe (S3). Une membrane de séparation (40) est formée sur les surfaces intérieures de la pluralité de cellules de filtration (C1). La pluralité de cellules de filtration (C1) comprennent des première et seconde cellules de filtration (C11, C12) qui sont adjacentes l'une à l'autre. La pluralité de cellules de collecte d'eau (C2) comprennent des cellules de collecte d'eau (C2) adjacentes aux premières cellules de filtration (C11) et séparées des secondes cellules de filtration (C12). Une première épaisseur de cloison (L1) pour un matériau de base (11) entre les premières cellules de filtration (C11) et les cellules de collecte d'eau (C2) est plus épaisse qu'une seconde épaisseur de cloison (L2) pour le matériau de base (11) entre les premières cellules de filtration (C11) et les secondes cellules de filtration (C12).
(JA) 多孔質支持体(10)は、両端面(S1,S2)において開口する複数の濾過セル(C1)と、両端面(S1,S2)において閉口する複数の集水セル(C2)と、複数の集水セル(C2)を貫いて外周面(S3)に開口する複数の排出流路(C3)とを有する。多孔質支持体(10)は、外周面(S3)を形成するモノリス型の基材(11)を含む。分離膜(40)は、複数の濾過セル(C1)の内表面に形成される。複数の濾過セル(C1)は、互いに隣接する第1及び第2濾過セル(C11,C12)を含む。複数の集水セル(C2)は、第1濾過セル(C11)に隣接し、かつ、第2濾過セル(C12)から離れた集水セル(C2)を含む。第1濾過セル(C11)と集水セル(C2)の間における基材(11)の第1隔壁厚み(L1)は、第1濾過セル(C11)と第2濾過セル(C12)の間における基材(11)の第2隔壁厚み(L2)よりも厚い。
