Abstract

L'INVENTION CONCERNE PLUS SPECIALEMENT L'AUGMENTATION DE L'EFFICACITE DU DESSICCATEUR D'UNE TELLE INSTALLATION ET LA SUPPRESSION DU BESOIN DE REMPLACER PERIODIQUEMENT SA MATIERE HYGROSCOPIQUE. SELON L'INVENTION, L'INSTALLATION EST MUNIE D'UN ECHANGEUR DE CHALEUR 2 QUE L'AIR COMPRIME VENANT DU COMPRESSEUR 1 TRAVERSE AVANT DE PARVENIR AU SEPARATEUR D'EAU 5 ET AU DESSICCATEUR 4. UN DISPOSITIF D'INVERSION COMPRENANT LA SOUPAPE DE TROP-PLEIN 6, UNE SOUPAPE ANTIRETOUR 14 ET UNE SOUPAPE DE COMMANDE 3 ENVOIE L'AIR SEC VENANT DU COMPRESSEUR 1 PENDANT LES PHASES DE MARCHE A VIDE EN SENS INVERSE A TRAVERS LE DESSICCATEUR 4 ET LE SEPARATEUR 5 POUR EN CHASSER L'EAU ET SECHER LA MATIERE HYGROSCOPIQUE.THE INVENTION MORE SPECIFICALLY CONCERNS INCREASING THE EFFICIENCY OF THE DRYER OF SUCH AN INSTALLATION AND THE ELIMINATION OF THE NEED TO PERIODICALLY REPLACE ITS HYGROSCOPIC MATERIAL. ACCORDING TO THE INVENTION, THE INSTALLATION IS EQUIPPED WITH A HEAT EXCHANGER 2 THAT THE COMPRESSED AIR COMING FROM COMPRESSOR 1 CROSSES BEFORE GOING TO WATER SEPARATOR 5 AND DRYER 4. A REVERSING DEVICE INCLUDING THE CONTROL VALVE OVERFLOW 6, A NON-RETURN VALVE 14 AND A CONTROL VALVE 3 SEND THE DRY AIR COMING FROM COMPRESSOR 1 DURING THE VACUUM OPERATION PHASES IN REVERSE DIRECTION THROUGH DRYER 4 AND SEPARATOR 5 TO DRAIN THE WATER AND DRY HYGROSCOPIC MATERIAL.
