ABSTRACT:
A fluid treating apparatus has a plurality of chambers arranged in a stack along the apparatus axis; inlet and outlet ports in end plates as well as a central channel for introducing fluid into and removing fluid from the apparatus; and a plurality of fluid-impervious diaphragms situated in a spaced relationship in the chambers in an orientation generally perpendicular to the axis. The fluid is guided along the diaphragms generally radially inwardly. The apparatus further has a plurality of support frames arranged in a stack along the axis. Each support frame includes an inner ring spacedly surrounded by an outer ring. The radially inner face of the outer ring and the radially outer face of the inner ring of each support frame together define radially outer and radially inner boundaries, respectively, of the chambers. The radially outer faces of the outer rings together form an outer wall face of the apparatus, and the radially inner faces of the inner rings surround the central channel. Each outer ring has a supporting face engaging a radially outer marginal surface portion of an adjoining diaphragm, and each diaphragm has a central aperture in axial alignment with each inner ring and a passage at a radially outer part for allowing flow of fluid axially through each diaphragm.
