DESCRIZIONE DESCRIPTION
Secondo l' invenzione in oggetto si viene a realizzare un essiccatoio continuo per poltiglie (sospensioni pompabili di pigmenti, argile, minerali), paste (pannelli dì filtrazione, fanghi di sedimentazione), polveri scorrevoli (precipitati, pigmenti, argille, cementi, cristalli, sabbia, minerali, gomma sintetica), nel quale il materiale viene essiccato in una atmosfera di vapore, come verrà precisato in seguito.-La vaporizzazione può essere sia per acqua che per tutti gli altri liquidi vaporizzagli che debbano essere separati dalla parte solida, come ad esempio i solventi. According to the invention in question, a continuous dryer for slurries (pumpable suspensions of pigments, clay, minerals), pastes (filtration panels, sedimentation sludge), flowing powders (precipitates, pigments, clays, cements, crystals, sand, minerals, synthetic rubber), in which the material is dried in a vapor atmosphere, as will be specified later. for example solvents.
Gli essiccatoi continui in uso, sia rotativi che a trasporto interno mediante coclea o nastro, sono riscaldati con fiamma diretta o con gas caldi, e tali suddetti aeriformi hanno la finizione di apportare il calore necessario al processo, e di asportare il vapore prodotto nel processo di essiccazione. The continuous dryers in use, both rotary and with internal transport by means of a screw or belt, are heated with direct flame or with hot gases, and these aforementioned aeriforms have the purpose of providing the necessary heat to the process, and of removing the steam produced in the process. drying.
La quantità di vapore asportato dall’aria che attraversa il cilindro, dipende dalla temperatura di bulbo bagnato del sistema, e si può ricavare dal diagramma di Mollier dell’aria umi da -ll valore della temperatura di bulbo bagnato dipende da molti elementi quali umidità iniziale dell’aria di processo prima del riscaldamento, valore della temperatura di riscaldamento, ingressi di aria parassita. -Gli elementi su menzionati non sono facilmente gestibili negli impianti di essicazione esistenti. -Bisogna inoltre considerare che la temperatura di bulbo bagnato del sistema che si viene ad instaurare, è anche la temperatura a cui si porta il materiale in fase di essiccazione.-E’ inoltre noto che l’alta temperatura del materiale da essiccare facilita il rilascio dell’acqua per la riduzione delle forze di legame con il materiale stesso. -Il fenomeno è perfettamente analogo anche con l’utilizzo di fiamme dirette.-Una medio-bassa temperatura di bulbo bagnato del sistema dà perciò medio-bassa velocità di essiccazione e medio-alta quantità d’aria necessaria al camino per l’asportazione del vapore. -Per ovviare a questi inconvenienti e ai limiti dei sistemi attualmente in uso, si è ideato e costruito un essiccatoio continuo che opera a temperatura di ebollizione.-Nella tavola di disegno, unita a puro titolo esemplificativo e non limitativo, la fig. 1 mostra lo schema di principio dell’essiccaloio ideato completo degli elementi che lo costituiscono.-Nel dettaglio esso si compone di un forno cilindrico coibentato 1, internamente ed adeguatamente riscaldato ad esempio tramite un bruciatore 2, mentre il materiale da essiccare, proveniente da una tramoggia 5, scorre entro un cilindro coassiale 3, spinto in continuo da una coclea 4 azionata a velocità variabile.-Il materiale essiccato si raccoglie nel recipiente 6 ed il vapore sviluppato, passa attraverso il condotto 7, condensa nel condensatore 8 e si raccoglie in 9. L’acqua fredda, o l’aria ambiente in ingresso del condensatore 8, si riscalda, esce dal condotto 10 e può essere utilizzata per riscaldamento od altro. The quantity of vapor removed from the air passing through the cylinder depends on the wet bulb temperature of the system, and can be obtained from the Mollier diagram of the air umi from - the wet bulb temperature value depends on many elements such as initial humidity process air before heating, heating temperature value, parasitic air inlets. -The elements mentioned above are not easily manageable in existing drying plants. -It must also be considered that the wet bulb temperature of the system that is established is also the temperature to which the material is brought during the drying phase. of water to reduce the bonding forces with the material itself. -The phenomenon is perfectly similar even with the use of direct flames. steam. -To obviate these drawbacks and the limitations of the systems currently in use, a continuous dryer has been designed and built that operates at boiling temperature. 1 shows the principle diagram of the devised dryer complete with its constituent elements. hopper 5, flows inside a coaxial cylinder 3, continuously pushed by an auger 4 operated at variable speed. 9. The cold water, or the ambient air entering the condenser 8, heats up, exits the duct 10 and can be used for heating or the like.
I prodotti della combusatione passano attraverso il condotto 1 , ed entrano in uno scambiatore di calore 12 prima di uscire dal camino 13, in modo da preriscaldare l’aria comburente di alimentazione del bruciatore 2 -L’essiccatoio nella realizzazione effettuata, ma non nella sua unica forma realizzativa possibile, è formato da un cilindro in acciaio inox 3 lambito all’esterno dai prodotti della combustione di un bruciatore a gas 2; il cilindro 3 è posto entro un forno cilindrico coibentato dal quale fuoriescono l’inizio e la fine del cilindro stesso. -I prodotti della combustione, immessi dentro il forno, dopo aver ceduto il loro calore sensibile al materiale da essiccare che passa nel cilindro 3, passano direttamente al camino senza essere miscelati a vapori e ad eventuali distillati che si possono ottenere negli essiccatoi a fiamma diretta e che possono presentare problemi di depurazione dei fumi prodotti.-Inoltre, negli attuali essiccatoi in uso, la miscela, prodotti della combustione e vapore, abbassa anche in modo sensibile il punto di rugiada acido dei soli prodotti della combustione, creando problemi di corrosione nell’impianto e nel camino di scarico. The combustion products pass through the duct 1, and enter a heat exchanger 12 before exiting the chimney 13, in order to preheat the combustion air supplying the burner 2 - The dryer in the implementation carried out, but not in its the only possible embodiment is formed by a stainless steel cylinder 3 lapped on the outside by the combustion products of a gas burner 2; cylinder 3 is placed within an insulated cylindrical oven from which the beginning and end of the cylinder itself come out. -The products of combustion, introduced into the oven, after having transferred their sensible heat to the material to be dried which passes into cylinder 3, pass directly to the chimney without being mixed with vapors and any distillates that can be obtained in direct flame dryers and which can present problems of purification of the produced fumes. system and in the exhaust chimney.
Nell’ essiccatoio ideato, l’avanzamento del materiale da essiccare viene realizzao mediante la coclea 4, alimentata dalla tramoggia 5 oppure da una pompa volumetrica 14 (nota per se) nel caso di materiale pompatole. -La coclea viene movimentata da un gruppo motoriduttore operante a giri variabili (nota per se).-Il sistema di alimentazione adottato realizza una tenuta contro In the designed dryer, the advancement of the material to be dried is carried out by means of the auger 4, fed by the hopper 5 or by a volumetric pump 14 (known per se) in the case of pumped material. - The auger is moved by a gearmotor unit operating at variable revolutions (known per se) - The power system adopted creates a seal against
