AIR DIFFUSION PIPE AND METHOD FOR WASHING AIR DIFFUSION PIPE

摘要

A diffusion pipe is provided in which the air diffusion efficiency can be quickly recovered just after conducting a cleaning process for the diffusion pipe with a cleaning solution supplied into the membrane support body, and in which air diffusion is evenly and constantly provided. The diffusion pipe 13 includes a membrane body 21 made of a viscoelastic material and formed in a tubular shape having an inner surface and an outer surface, and a tubular membrane support body 20 that supports the membrane body 21 from inside of the membrane body 21. The membrane body 21 has a plurality of diffusion slits 21a cutting therethrough between the outer surface and the inner surface. The membrane support body 20 has through-holes 20a on an upper side and a lower side thereof. The diffusion slits 21a are not provided in a region of the membrane body 21 corresponding to the through-holes 20a.
