ABSTRACT:
This invention pertains to apparatus for removing heating or cooling fluid from a rotary heat exchange device comprising a hollow shell defining a shell chamber with an inner surface and an outer surface. The shell has first and second ends and a generally horizontal longitudinal axis extending between the ends. Thus, the shell defines axial directions along the axis, radial directions transverse to the axis and circumferential directions around the axis. The exchanger desirably also includes an inlet means for admitting a heat exchange fluid such as steam into the shell, and a shaft extending along the longitudinal axis, the shaft being at least partially hollow so as to define a shaft chamber. The apparatus also includes at least one set of collecting members, and typically involves several sets of such members. Each set of collecting members includes first and second radially-extensive and axially-extensive collecting members, mounted for rotation in unison with one another about the axis. The first collecting member extends radially inwardly from the inner surface of the shell, and the second collecting member is spaced apart from the first collecting member in a first circumferential direction so that the first and second collecting members of each set define a collection space therebetween. Each collection space communicates with the shell chamber at the second collecting member adjacent the interior surface of the shell.
