TURBOLATORE PER TUBO DI CONVOGLIAMENTO DI FUMI IN APPARECCHIO DI SCAMBIO TERMICO TURBULATOR FOR SMOKE CONVEYING PIPE IN HEAT EXCHANGE EQUIPMENT

DESCRIZIONE DESCRIPTION

Il trovato si riferisce ad un turbolatore per tubo di convogliamento di fumi in apparecchio di scambio termico. The invention relates to a turbulator for a pipe for conveying fumes in a heat exchange apparatus.

E' nota la presenza di apparecchi di scambio termico, quali, ad esempio, le caldaie a tubi di fumo per la produzione di acqua calda o di altri fluidi vettori, che prevedono la presenza di tubi destinati al convogliamento di fumi prodotti dalla combustione in appositi focolari, inseriti nell'ambito di una capacità contenente il fluido da riscaldare. The presence of heat exchange devices is known, such as, for example, the smoke tube boilers for the production of hot water or other carrier fluids, which require the presence of tubes intended for conveying the fumes produced by combustion in special hearths, inserted within a capacity containing the fluid to be heated.

Tubi di questo tipo non sono comunque tipici esclusivamente delle caldaie, ma possono essere presenti anche in apparecchi diversi di cicli industriali . In any case, pipes of this type are not exclusively typical of boilers, but can also be present in different appliances of industrial cycles.

All'interno dei detti tubi di convogliamento dei fumi viene sovente inserito un elemento, denominato turbolatore, con la precisa funzione di rompere lo strato limite della corrente di fumi a contatto con la superficie interna dei tubi, ed una forma costruttiva molto comune dell'elemento turbolatore è costituita da una semplice spirale di filo metallico che viene appunto disposta in aderenza alla detta superficie interna dei tubi. Questa forma di realizzazione non risulta però particolarmente efficace, ed è allora compito del presente trovato quello di realizzare un elemento turbolatore che svolga in modo ottimale la funzione di creare turbolenza nell'ambito della corrente di fumi, così da ottimizzare la trasmissione del calore tra i fumi stessi ed il fluido da riscaldare. An element, called turbulator, is often inserted inside said smoke conveyor pipes, with the precise function of breaking the boundary layer of the smoke stream in contact with the internal surface of the pipes, and a very common construction form of the element turbulator consists of a simple spiral of metal wire which is precisely arranged in adherence to said internal surface of the pipes. However, this embodiment is not particularly effective, and it is therefore an object of the present invention to provide a turbulator element which performs in an optimal way the function of creating turbulence within the flue stream, so as to optimize the transmission of heat between the fumes themselves and the fluid to be heated.

Il compito proposto viene raggiunto da un turbolatore per tubo di convogliamento dei fumi in apparecchio di scambio termico, secondo il trovato, caratterizzato dal fatto di comprendere almeno due spirali realizzate in filo metallico, destinate ad essere inserite nel detto tubo in aderenza alla superficie interna dello stesso, affiancate e rese reciprocamente solidali mediante almeno un elemento di collegamento. The proposed aim is achieved by a turbulator for the pipe for conveying the fumes in a heat exchange apparatus, according to the invention, characterized in that it comprises at least two spirals made of metal wire, intended to be inserted in said pipe adhering to the internal surface of the itself, placed side by side and made mutually integral by means of at least one connecting element.

Ulteriori caratteristiche e vantaggi risulteranno maggiormente dalla descrizione di una forma di esecuzione preferita ma non esclusiva del trovato, illustrata a titolo indicativo e non limitativo negli uniti disegni in cui: Further characteristics and advantages will become clearer from the description of a preferred but not exclusive embodiment of the invention, illustrated by way of non-limiting example in the accompanying drawings in which:

la figura 1 rappresenta un turbolatore secondo la tecnica nota, parzialmente inserito in un tubo di convogliamento di fumi; Figure 1 shows a turbulator according to the known art, partially inserted in a pipe for conveying fumes;

la figura 2 rappresenta la sezione con il piano II-II di figura 1; Figure 2 represents the section with the plane II-II of Figure 1;

la figura 3 rappresenta il turbolatore secondo il trovato; Figure 3 shows the turbulator according to the invention;

la figura 4 rappresenta la sezione con il piano IV-IV di figura 3. figure 4 represents the section with the plane IV-IV of figure 3.

Con riferimento alle suddette figure 1 e 2, è indicato con 1 il tubo di convogliamento dei fumi nel quale è presente il turbolatore 2 formato secondo la tecnica nota da una sola spirale di filo metallico, inserito a contatto con la superficie interna del tubo 1, come messo in rilievo dalla figura 2. With reference to the aforementioned figures 1 and 2, 1 indicates the pipe for conveying the fumes in which the turbulator 2 is present, formed according to the known art from a single spiral of metal wire, inserted in contact with the internal surface of the pipe 1, as highlighted in figure 2.

La figura 3 mostra il turbolatore 3 secondo il trovato che comprende due spirali 3a, 3b sostanzialmente identiche, realizzate in filo metallico, affiancate e rese solidali mediante un elemento di collegamento costituito dalla barretta 3c ad esse saldata. Figure 3 shows the turbulator 3 according to the invention which comprises two substantially identical spirals 3a, 3b, made of metal wire, placed side by side and made integral by means of a connection element constituted by the bar 3c welded to them.

Questo turbolatore 3 risulta molto efficace nell 'impedire la formazione di uno strato limite della corrente di fumi a contatto con la superficie interna della parete del tubo, e la turbolenza che ne deriva crea condizioni ottimali alla trasmissione del calore tra i fumi ed il fluido da riscaldare che circonda il tubo. This turbulator 3 is very effective in preventing the formation of a boundary layer of the smoke stream in contact with the internal surface of the pipe wall, and the resulting turbulence creates optimal conditions for the transmission of heat between the fumes and the fluid to be heat surrounding the tube.

Il trovato descritto è suscettibile di numerose modifiche e varianti, tutte rientranti nell'ambito del concetto inventivo: così, ad esempio, potranno essere presenti spirali in numero superiore a due. In pratica i materiali impiegati, purché compatibili con l'uso specifico, nonché le dimensioni e le forme potranno essere qualsiasi, a seconda delle esigenze. The described invention is susceptible of numerous modifications and variations, all of which are within the scope of the inventive concept: thus, for example, spirals greater than two may be present. In practice, the materials employed, so long as they are compatible with the specific use, as well as the dimensions and shapes, may be any according to requirements.

Inoltre, tutti i dettagli sono sostituibili da altri elementi tecnicamente equivalenti. Furthermore, all the details can be replaced by other technically equivalent elements.
