Description
Procedimento per la pulizia dei tubi interni dei vapore e dell’acqua dei forni che bruciano carbone , immondizie e simili per la produzione di energia elettrica, smaltimento di rifiuti e simili. Procedure for cleaning the internal steam and water pipes of furnaces that burn coal, garbage and the like for the production of electricity, waste disposal and the like.
E’ noto che i forni che bruciano carbone , immondizie ed altri materiali per la produzione di energia elettrica, o per altre funzioni , presentano il problema dell’accumulo dei residui della combustione sui tubi del vapore dell’acqua, tali residui causano notevoli problemi per l'efficacia del vapore acqua calda e la produzione di energia elettrica Attualmente i metodi per effettuare la pulizia dalle scorie prevedono l'abbassamento della temperatura del forno fino a 20/30 gradi C, ed una azione di pulizia per mezzo di sabbiatrici o similari. It is known that ovens that burn coal, garbage and other materials for the production of electricity, or for other functions, have the problem of the accumulation of combustion residues on the steam pipes of the water, these residues cause considerable problems for the effectiveness of steam, hot water and the production of electricity Currently, the methods for cleaning waste include lowering the temperature of the oven up to 20/30 degrees C, and a cleaning action by means of sandblasters or the like.
Questo metodo comporta notevoli svantaggi economici dovuti, sia alla perdita di produttività ,in quanto è necessario attendere diverso tempo per il raffreddamento , rimuovere le scorie e riportare il forno alla temperatura di esercizio, sia al costo in combustibile necessario per riportare il formo alla temperatura di esercizio dopo che come detto la temperatura è stata abbassata a 20 /30 gradi C°. This method involves considerable economic disadvantages due both to the loss of productivity, as it is necessary to wait a long time for cooling, to remove the slag and bring the furnace back to operating temperature, and to the fuel cost necessary to bring the mold back to the operating temperature. exercise after, as mentioned, the temperature has been lowered to 20/30 degrees C °.
Oggetto della presente invenzione, è un metodo per la rimozione delle scorie dei tubi interni del vapore e dell’acqua, che ovvia agli inconvenienti descritti, permettendo la pulizia mantenendo la temperatura del forno a quella di esercizio. The subject of the present invention is a method for removing slag from the internal steam and water pipes, which obviates the drawbacks described, allowing cleaning while maintaining the temperature of the oven at the operating temperature.
Secondo la presente invenzione, il metodo prevede che vengano scaricato, carbone compresso, o legno configurato da forme e dimensioni diverse o liquidi congelati per mezzo di aria compressa o acqua o qualsiasi altro mezzo utile. According to the present invention, the method provides that compressed coal, or wood configured of different shapes and sizes or frozen liquids by means of compressed air or water or any other useful means are discharged.
Le palline con componenti scelti si muovo ad velocità per scorificare i tubi coperti e rimuovere le scorie grazie all’impatto ed al rapido raffreddamento delle scorie che cambiano la tensione e l'incrinatura. Il metodo è particolarmente efficace quando il forno è in piena attività e quindi ad una temperatura superiore ai 1000 gradi C. The balls with selected components move at speed to slag the covered pipes and remove the slag thanks to the impact and rapid cooling of the slag that changes the tension and crack. The method is particularly effective when the oven is in full operation and therefore at a temperature above 1000 degrees C.
Quanto fino ad ora sommariamente detto potrà essere meglio compreso dalla descrizione di un esempio realizzativo dato con riferimento al disegno allegato in cui: What has been summarized up to now can be better understood from the description of an embodiment given with reference to the attached drawing in which:
La fig. 1 mostra un schema di funzionamento del metodo Fig. 1 shows a scheme of operation of the method
Secondo la presente invenzione, il procedimento per la pulizia dei tubi interni del vapore e dell’acqua dei forni (5) che bruciano carbone , immondizie e simili per la produzione di energia elettrica, consiste neH'utilizzazione di una unità attiva (1) ,ad esempio una lancia a gas pressurizzato ,che rilascia aria /gas compressi nel tamburo nella quale sono posizionate le palline di materiale ad, esempio come detto carbone compresso, o legno configurato da dimensioni diverse o liquidi congelati (2) . According to the present invention, the process for cleaning the internal steam and water pipes of the furnaces (5) which burn coal, garbage and the like for the production of electricity, consists in the use of an active unit (1), for example a pressurized gas lance, which releases compressed air / gas into the drum in which the balls of material are positioned, for example as said compressed coal, or wood configured with different dimensions or frozen liquids (2).
I meccanismi di espulsione possono ovviamente anche essere differenti da quello descritto come ad esempio meccanismi a molle, idraulici, elettrici, a detonatore e via dicendo. The ejection mechanisms can obviously also be different from the one described, such as spring, hydraulic, electric, detonator mechanisms and so on.
La pallina di materiale o liquido congelato può ,ma non deve, essere riempita al 100% , ma può anche avere all'interno una piccola tasca di aria /gas tenendo comunque presente che la variazione del rapporto di riempimento può essere fatta senza modifiche significative per l'efficienza. The ball of frozen material or liquid can, but must not, be filled to 100%, but it can also have a small air / gas pocket inside, keeping in mind that the variation of the filling ratio can be made without significant changes to efficiency.
La velocità con cui il materiale viene scaricato è un elemento importante per l’efficacia del procedimento. The speed with which the material is unloaded is an important element for the effectiveness of the procedure.
II dispositivo (1) di sparo delle (2) cartucce viene puntato contro i tubi di vapore/acqua (4) ed indirizzato contro i residui (3) da rimuovere , Da esperimenti effettuati è stato rilevato che una velocità di 100m/sec è ottimale per ottenere buoni risultati. The firing device (1) of the (2) cartridges is pointed at the steam / water pipes (4) and directed against the residues (3) to be removed, From experiments carried out it has been found that a speed of 100m / sec is optimal. for good results.
Quando la pallina di materiale colpisce l’obiettivo si rompe e rimuove le scorie dai tubi interni del forno mentre il forno è in funzione . When the ball of material hits the lens it breaks and removes the slag from the internal tubes of the oven while the oven is in operation.
Il puntamento ed il tiro sono eseguiti dalle aperture laterali sui lati del forno (5). Aiming and firing are performed from the side openings on the sides of the oven (5).
E' evidente, da quanto fino ad ora descritto ed illustrato, che sono possibili variazioni sia alla composizione dell'involucro che contiene il composto acqua polvere - solidi palline ecc. , che al composto stesso senza per questo esulare dall’ambito del brevetto e delle rivendicazioni che seguono. It is evident, from what has been described and illustrated up to now, that variations are possible both in the composition of the envelope which contains the compound water powder - solid pellets etc. , which to the compound itself without thereby going beyond the scope of the patent and the claims that follow.
