Abstract
Il trovato consiste nella installazione di un filtro automatico "a secco" direttamente sopra gli idratatori per calce. In tal modo si depolverano i vapori che si sprigionano carichi di particelle finissime di idrato di calce, quando sono ancora allo stato secco, surriscaldato. Questa depolverazione con recupero delle polveri asciutte effettuata direttamente sopra la vasca dell'idratatore determina:1) il totale recupero entro l'idratatore delle polveri emesse durante la lavorazione;2) l'immediata successiva possibilità di impiegare utilmente il vapore filtrato, esente da polvere, per il preriscaldamento pulito dell'acqua necessaria all'idratazione della calce;3) evita i problemi di sporcamento e carbonatazione riscontrati fino ad ora nei camini e negli attuali depolveratori - preriscaldatori ad umido (di scarsa efficienza), che sino ad ora sono impiegati nell'industria della calce con grossi problemi di gestione;4) garantisce l'osservanza della normativa che regola le emissioni in atmosfera.The invention consists in the installation of an automatic "dry" filter directly above the lime hydrators. In this way the vapors are dusted off and they are released loads of very fine lime hydrate particles, when they are still in the dry, overheated state. This dedusting with recovery of dry powders carried out directly above the hydrator tank determines: 1) the total recovery of the powders emitted during processing within the hydrator; 2) the immediate subsequent possibility of usefully using the filtered steam, free of dust , for the clean preheating of the water necessary for the hydration of the lime; 3) avoids the problems of soiling and carbonation found so far in the chimneys and in the current dust collectors - wet preheaters (of poor efficiency), which until now are used in the lime industry with major management problems; 4) ensures compliance with the regulations governing emissions into the atmosphere.
