Title
(EN) HOLLOW FIBER MEMBRANE DEHUMIDIFIER
(FR) DÉSHUMIDIFICATEUR À MEMBRANE À FIBRES CREUSES
(JA) 中空糸膜除湿装置
Abstract
(EN)
Assembling performance, handling performance, sealing performance, and dehumidification performance of a hollow fiber membrane module are enhanced while achieving downsizing of a hollow fiber membrane dehumidifier. The hollow fiber membrane dehumidifier includes a dehumidification container (67) composed of a lower trunk (38) provided with an exhaust gas inlet (63), an upper trunk (37) provided with an exhaust gas outlet (58), and a body trunk (33); a lower tube sheet (35) for constructing an exhaust gas inlet chamber (39) in the body trunk (33); an upper tube sheet (34) for constructing an exhaust gas outlet chamber (42) in the body trunk (33); a partition plate (36) for partitioning the interior of the body trunk (33) to an exhaust gas processing chamber (40) and a purge gas chamber (41); a plurality of hollow fiber membrane modules (44) inserted into each through hole of an upper tube sheet (34), the partition plate (36), and the lower tube sheet (35); and a sealing material held in the sealing groove formed in the hollow fiber membrane module (44) for sealing among an upper head (54), a lower head (50), the upper tube sheet (34), the partition plate (36), and the lower tube sheet (35).

L'invention concerne la performance d'assemblage, la performance de manipulation, la performance d'étanchéité et la performance de déshumidification d'un module à membrane à fibres creuses qui sont améliorées tout en arrivant à réduire la taille d'un déshumidificateur à membrane à fibres creuses. Le déshumidificateur à membrane à fibres creuses comprend un contenant de déshumidification (67) composé d'un tronc inférieur (38) pourvu d'un orifice d'admission de gaz d'échappement (63), d'un tronc supérieur (37) pourvu d'un orifice de sortie de gaz d'échappement (58) et d'un tronc support (33) ; une plaque tubulaire inférieure (35) pour construire une chambre d'entrée de gaz d'échappement (39) dans le corps support (33) ; une plaque tubulaire supérieure (34) pour construire une chambre de sortie de gaz d'échappement (42) dans le tronc support (33) ; une plaque de séparation (36) pour séparer l'intérieur du tronc support (33) en une chambre de traitement de gaz d'échappement (40) et une chambre de gaz de purge (41) ; une pluralité de module à membrane à fibres creuses (44) insérés dans chaque trou traversant d'une plaque tubulaire supérieure (34), de la plaque de séparation (36) et de la plaque tubulaire inférieure (35) ; et un matériau d'étanchéité maintenu dans la rainure d'étanchéité formée dans le module à membrane à fibres creuses (44) pour tenir de façon étanche une tête supérieure (54), une tête inférieure (50), la plaque tubulaire supérieure (34), la plaque de séparation (36) et la plaque tubulaire inférieure (35).
