Abstract
A heat exchanger is disclosed, comprising a shell housing a rotor. The rotor comprises a series of hollow bodies whose interiors are hydraulically connected to each other and which are secured to a shaft which is rotatably mounted in the shell. One liquid flows through the shell in contact with the exterior of the hollow bodies. Part of the shaft is hollow to permit flow through the shaft and the hollow bodies of a second liquid. Diaphragms are disposed in the hollow bodies to regulate the flow of fluid therethrough. The shell preferably comprises large diameter fittings. The second liquid is preferably dense and may comprise sludge, waste water, etc.
Claims22
A heat exchanger, comprising:
- a shell;
- a hollow rotor rotatably housed in said shell;
- said rotor having a longitudinal axis about which it is rotatable;
- said rotor being adapted to conduct heat between its interior and its exterior;
- said shell being adapted to have a first fluid flow therethrough in thermal contact with said rotor, and said rotor being adapted to have a second fluid flow longitudinally therethrough to effect heat exchange between the first and second fluids;
- the interior of said rotor being hydraulically sealed from the remainder of the interior of said shell;
- said rotor comprising a plurality of hollow bodies whose interiors communicate with each other;
- each said hollow body containing a diaphragm for regulating the flow of a fluid therethrough;
- each said hollow body cooperating with said diaphragm located therein to define a constricted region to divide said hollow body into a plurality of communicating chambers for regulating the flow of a fluid through said hollow body;
- mounting means for rotatably mounting said rotor in said shell;
- and
- means for rotating said rotor, including said hollow bodies and said diaphragms.
