Abstract

221,957. Ries, F. Sept. 21, 1923. No Patent granted (Sealing fee not paid). Rotary apparatus.-Apparatus for condensing steam or for cooling or heating fluids comprises a casing and a series of thin-walled open-ended vessels of substantially cylindrical form mounted on a rotating shaft and having one end opening of larger radius than the other. Liquid admitted to the cylinders at the narrower ends is spread by centrifugal force in thin layers over the surface of the cylinders and is flung out at the wider ends, exchanging heat in passage with a fluid which may be introduced into the casing at either end. In the example shown in Fig. 2, steam enters the casing a at f and is condensed by cooling water from the jet b spread alternatively by the rotating cylinders e<1>, e<2>, e<3> attached to the discs k<1>, k<2> fixed to the shaft c. In Fig. 6, which shows a preheater for liquids, the liquid to be heated enters at g into the rotor b comprising a single set of cylinders e. In a modification, a set of cylinders is arranged on each side of common steam and water inlets, while in a further example the entering fluid causes the rotation of the cylinders by striking blades formed on one end of the cylinders.
