PURPOSE:To enhance the efficiency of energy, by providing a nozzle for injecting seawater into a rotor, and by forming, in the wall surface of the rotor, receiving surfaces for receiving injected fluid in a such a form that the receiving surfaces are concave in the rotating direction of the rotor. CONSTITUTION:An output shaft 3 is disposed in the casing 2 of an energy recovery device 1, and is coupled thereto with a hollow drum-like rotor 6. Further, predesalted seawater is fed into the rotor 6 and is injected fro a nozzle 11. Grooves 13 are formed at predetermined pitches, having receiving surfaces 14 and feeding surfaces 15 to smoothen the impinging force of jet stream. With this arrangement, even if the flow rate of seawater is less, the energy is efficiently converted into a rotational motion. |
