Abstract:
1. A device for the homogeneous distribution and dispersion of a fluid within an enclosure, comprising a diffusion chamber designated to be located at least partially inside the enclosure, substantially on the axis of a conduit supplying fluid to the enclosure, and to be inserted into the conduit, wherein the diffusion chamber comprises on the totality of its lateral walls means of discharging the fluid into a section of the enclosure being filled, and wherein the diffusion chamber comprises a single-unit assembly comprising: a first perforated plate, designed to be located upstream in the direction of fluid flow and allowing the supply of fluid to the diffusion chamber; a second perforated plate located downstream and designed to evacuate part of the fluid towards the inside of the enclosure, the first and second perforated plates having a shape and dimensions substantially identical to those of a transversal section of the conduit to be fitted, and being pierced with holes distributed in a substantially regular fashion across their surface; lateral bands, regularly spaced from one another, placed perpendicularly to the first and second perforated plates and joining them at their periphery, either directly or by means of a skirt; and at least one insert comprising a ring-shaped crown of an outer diameter identical to the inner diameter of the diffusion chamber, the ring-shaped crown being placed perpendicularly to the axis of the supply conduit and projecting towards the inside of the diffusion chamber from the lateral wall or walls thereof, to which it is rigidly affixed, such as to form a lateral obstacle to the flow of the fluid, wherein the surface area of the at least one insert is sufficient for creating, in an upstream section of the diffusion chamber, a pressure superior to that in a downstream section, such as to enforce the supply of fluid to the outermost region of a transversal section of the enclosure.
