ABSTRACT:
A rotary separator is described, of the type which includes membrane packs lying in a rapidly rotating chamber, which provides ready access to the chamber to change or inspect membrane packs, as well as ready access to at least one dynamic seal. The rotary frame includes upper and lower parts (40, 42) forming a chamber (22) between them and held together by bolts. The lower part (42) is rotatably supported by a pair of bearings (60, 62), but the upper part (40) is not directly supported by bearings. A pair of concentric conduits (20, 30) extend through the lower part, but not the upper part (40). The conduits include an inner conduit in the form of a pipe whose top (86) lies slightly within the chamber and which is sealed thereat by a dynamic seal 80. The top part (40) can be readily removed to provide access to the membrane packs (44) and to the inner conduit seal (80).
