Abstract

PURIFICATION DE FUMEES POLLUANTES ET SYSTEME DE RECUPERATION DE CHALEUR. LA SORTIE DES FUMEES 3 ET L'ENTREE D'AIR DE SECHAGE 4 SONT RELIEES EN SERIE L'UNE A L'AUTRE AVEC INTERPOSITION DE DEUX ECHANGEURS DE CHALEUR 5 ET 6 ET D'UN GENERATEUR D'AIR CHAUD 9, LE PREMIER 5 DESDITS ECHANGEURS DE CHALEUR TRANSFERANT LA CHALEUR DES FUMEES A PURIFIER AU CONTRE-COURANT D'AIR DU SECOND 6 DESDITS ECHANGEURS DE CHALEUR, EN CE QUE LE SECOND DE CESDITS ECHANGEURS DE CHALEUR EST DU TYPE A "MELANGE D'EAU" ET PURIFIE, PAR CONDENSATION DE LA VAPEUR ENGENDREE DURANT LE PROCEDE DE SECHAGE, LESDITES FUMEES POLLUANTES, EN CE QUE L'EAU DE REFROIDISSEMENT DANS LE SECOND 6 DESDITS ECHANGEURS DE CHALEUR EST FOURNIE POUR LE REFROIDISSEMENT D'UN TROISIEME ECHANGEUR DE CHALEUR 7 DU TYPE A "MELANGE D'EAU", EN CE QUE LE SYSTEME EST ACTIONNE PAR UN MOTEUR THERMIQUE 27 DONT LES GAZ D'ECHAPPEMENT SONT DIRIGES VERS LEDIT GENERATEUR D'AIR CHAUD 9, EN CE QUE ENTRE LE SECOND 6 DESDITS ECHANGEURS DE CHALEUR ET LEDIT GENERATEUR D'AIR CHAUD 9, UNE QUANTITE D'AIR NON POLLUEE EST SOUTIREE POUR ETRE EVACUEE DANS L'ATMOSPHERE, LADITE QUANTITE D'AIR NON POLLUE ETANT EGALE A LA QUANTITE D'AIR REQUISE POUR LA COMBUSTION DU COMBUSTIBLE UTILISE DANS LEDIT MOTEUR THERMIQUE 27 ET LEDIT GENERATEUR D'AIR CHAUD 9. APPLICATION AUX SECHOIRS.PURIFICATION OF POLLUTING FUMES AND HEAT RECOVERY SYSTEM. THE SMOKE OUTLET 3 AND THE DRYING AIR INLET 4 ARE CONNECTED IN SERIES TO ONE ANOTHER WITH THE INTERPOSITION OF TWO HEAT EXCHANGERS 5 and 6 AND OF A HOT AIR GENERATOR 9, THE FIRST 5 OF THE SAID HEAT EXCHANGERS TRANSFERRING THE HEAT OF THE FUMES TO BE PURIFIED TO THE BACKFLOW OF AIR FROM THE SECOND 6 OF THE SAID HEAT EXCHANGERS, IN THAT THE SECOND OF THESE said HEAT EXCHANGERS IS OF THE "WATER MIXTURE" TYPE AND PURIFIED, BY CONDENSATION OF THE STEAM GENERATED DURING THE DRYING PROCESS, THE SAID POLLUTANT FUMES, IN THAT THE COOLING WATER IN THE SECOND 6 OF THE SAID HEAT EXCHANGERS IS PROVIDED FOR COOLING A THIRD HEAT EXCHANGER 7 OF TYPE A " 'WATER', IN THAT THE SYSTEM IS ACTUATED BY A THERMAL ENGINE 27 OF WHICH THE EXHAUST GASES ARE DIRECTED TO THIS HOT AIR GENERATOR 9, IN THAT BETWEEN THE SECOND 6 OF SAID HEAT EXCHANGERS AND ITS AIR GENERATOR HOT 9, AN AMOUNT OF NON-POLLUTED AIR IS SUPPLIED TO BE EV ACUE IN THE ATMOSPHERE, THE SAID QUANTITY OF NON-POLLUTED AIR BEING EQUAL TO THE QUANTITY OF AIR REQUIRED FOR THE COMBUSTION OF THE FUEL USED IN SIDI THERMAL ENGINE 27 AND ITS HOT AIR GENERATOR 9. APPLICATION TO DRYERS.
