ROTOR ZUM EINSATZ IN TAUSCHERN ZUR WIEDER- GEWINNUNG VON FEUCHTIGKEIT UND INSBESONDERE AUCH VON WAERME, DURCH TRANSFER ZWISCHEN ZWEI GASSTROEMEN

摘要

The rotor is assembled from foils which are alternately constructed as planar and corrugated. The foils form a multiplicity of continuous parallel flow ducts for the gas stream. The foils consist of aluminium or a non-metallic substrate coated with aluminium. A porous layer of aluminium hydroxide is formed on the surfaces of the foils in at least one treatment operation by precipitation from a solution of sodium aluminate. The rotor has outstanding hygroscopic properties, the production method being simple and the material costs slight.
