A fine bubble diffusing tube that can generate fine bubbles evenly and uniformly even when the diffusing tube has a long length, a fine bubble diffusing device using such a tube and a submerged membrane separation apparatus are produced, and in order to achieve these, the fine bubble diffusing tube is provided with at least a cylindrical supporting tube 1, and an elastic sheet 2 with fine slits formed therein, with the elastic sheet 2 being placed so as to cover the outer circumference of the supporting tube 1, so that, upon supplying a gas to a space between the elastic sheet 2 and the supporting tube 1, the fine slits of the elastic sheet 2 are opened to generate fine bubbles outside the diffusing tube, and in this structure, the supporting tube 1 has a length L of 1000 mm or more in the longitudinal direction, with gas supply units 4 serving as gas flow inlets being attached to the two ends of the supporting tube.

L'invention vise à proposer un tuyau de diffusion de fines bulles apte à produire de fines bulles efficacement et de façon uniforme et homogène même si le tuyau de diffusion est allongé, et un dispositif de diffusion de fines bulles et un dispositif de séparation de film du type à trempage utilisant le tuyau de diffusion de fines bulles. Ce tuyau de diffusion de fines bulles comprend un tuyau de support cylindrique (1) et une feuille élastique (2) comportant de fines fentes formées dans celle-ci. La feuille élastique (2) est configurée de façon à recouvrir la périphérie externe du tuyau de support (1). Lorsque l'espacement entre la feuille élastique (2) et le tuyau de support (1) reçoit un gaz, les fines fentes de la feuille élastique (2) sont ouvertes de façon à remplir la fonction de production des fines bulles d'air vers l'extérieur du tuyau de diffusion. Le tuyau de diffusion de fines bulles est caractérisé par le fait que le tuyau de support (1) a une longueur longitudinale (L) de 1 000 mm ou plus, et par le fait que le tuyau de support est équipé, à ses deux extrémités, de parties d'alimentation en gaz (4) jouant le rôle d'orifices d'entrée de gaz.
