Abstract
(EN)
A screw rod expansion power generating device (1) can be used in an organic rankine cycle. The power generating device (1) comprises a semi-enclosed or totally-enclosed housing. A screw rod expander and a generator (101) are arranged in the housing. A rotor (102) of the screw rod expander is fixedly connected with a rotor of the generator. The generator (101) is driven to produce electricity through the rotation of the rotor (102) of the screw rod expander. A gas inlet (107) and a gas outlet (108) of the screw rod expander are arranged on the housing. A gas flow which enters the housing from the gas inlet (107) and is discharged from the gas outlet (108) of the expander passes through the generator (101) so as to cool the generator (101). The screw rod expansion power generating device (1) is semi-enclosed or totally-enclosed. The screw rod expander and the generator (101) are arranged in the housing as a whole. The generator (101) can be a synchronous generator or an asynchronous generator. When the screw rod expansion power generating device (1) produces electricity, leakage of a refrigerating working medium can be avoided.

L'invention concerne un dispositif (1) générateur d'énergie doté d'un dispositif d'expansion à tige à tarière et destiné à être utilisé dans un cycle de Rankine organique. Le dispositif (1) de génération d'énergie comprend un carter semi-fermé ou entièrement fermé. Un dispositif d'expansion à tige à tarière et un générateur (101) sont disposés dans le carter. Un rotor (102) du dispositif d'expansion à tige à tarière est fixement connecté au rotor du générateur. Le générateur (101) est entraîné pour produire de l'électricité par la rotation du rotor (102) du dispositif d'expansion à tige à tarière. Une entrée de gaz (107) et une sortie de gaz (108) du dispositif d'expansion à tige à tarière sont pratiquées dans le carter. Un écoulement de gaz qui entre dans le carter par l'entrée de gaz (107) et est déchargé par la sortie de gaz (108) du dispositif d'expansion, traverse le générateur (101) de manière à refroidir le générateur (101). Le dispositif (1) de génération d'énergie doté d'un dispositif d'expansion à tige à tarière est semi-fermé ou entièrement fermé. Le dispositif d'expansion à tige à tarière et le générateur (101) sont disposés dans le carter sous la forme d'une seule unité. Le générateur (101) peut être un générateur synchrone ou un générateur asynchrone. Lorsque le dispositif (1) de génération d'énergie doté d'un dispositif d'expansion à tige à tarière produit de l'électricité, toute fuite d'un médium opérationnel de refroidissement peut être évitée.
