Method and device for internal accumulation and circulation of thermally treated fluid

Abstract

A device adapted to accumulate a thermally treated includes: a containment chamber of the thermally treated fluid ( 1 ), at least one separator ( 4 ) arranged with a substantially vertical development in the containment chamber, at least one separator being adapted to divide the chamber in at least two parts, and to leave openings at the opposite upper ( 6 ) and lower ( 7 ) end of the chamber, by means of which the fluid can pass in order to determine a rotatory circulation of the fluid in the cross direction in the chamber.

1 . A device adapted to accumulate a thermally treated fluid, comprising:
 a containment chamber of said thermally treated fluid; and   at least one separator arranged with a substantially vertical development in the containment chamber, said at least one separator being adapted to divide said chamber in at least two parts, and to leave openings at the opposite upper and lower end of said chamber, through which openings the fluid can pass in order to determine a rotatory circulation of the fluid in the cross direction in said chamber.   
     
     
         2 . The device as in  claim 1 , further comprising at least one heat exchange element arranged in the containment chamber, in one of said parts of the chamber. 
     
     
         3 . The device as in  claim 2 , wherein at least one of said parts of the chamber is without heat exchange elements. 
     
     
         4 . The device as in  claim 1 , wherein said containment chamber has a cylindrical configuration, or ovoid, or polygonal, or oval, or parallelepiped with or without chamfered angles, developed in a substantially horizontal or vertical direction. 
     
     
         5 . The device as in  claim 2 , wherein said at least one heat exchange element comprises more parallel longitudinal heat exchangers, with equal or different diameters, in fixed or extractable version. 
     
     
         6 . The device as in  claim 2 , wherein said at least one heat exchange element comprises one or more linear or non-linear heat exchangers, or coils, or corrugated or finned heat exchangers, or at least a partially hollow space. 
     
     
         7 . The device as in  claim 1 , wherein said separator is a simple plate, or an element comprising an insulation, for a better thermal separation between the parts into which the internal chamber is divided. 
     
     
         8 . The device as in  claim 1 , wherein said separator has an elongated configuration with a straight or curved cross section. 
     
     
         9 . The device as in  claim 2 , wherein said chamber is a furnace, and said at least one heat exchange element is one or more series of heating elements. 
     
     
         10 . A method for accumulating thermally treated fluid, the method comprising:
 providing a device according to any one of the preceding claims; and   introducing a fluid to be treated thermally in said device, in order to obtain a cross rotatory motion of said fluid within said device.
