Claim:
Distributor nozzle for a two-phase charge in fixed-bed reactors, comprising: a deflector cone or deflector cone frustum that can be either solid or hollow, depending on its shape and manufacturing process, and which has a variable angle, or alternatively more than one angle, for improving the distribution and reducing the dry area in the “shadow” of the deflector cone or deflector cone frustum; fixing bars or legs for fixing the cone in the shaft, which are vertical or inclined towards the inside or outside wall of the shaft and extend from the top, bottom or side of the deflector cone or cone frustum; flow-redirecting devices to ensure the wetting of the region that lies directly below the cone, which devices may be formed by small channels, holes or slits in the deflector cone, by vertical extensions of the cone itself in the form of “teeth” or by a combination of these devices with the legs, in order to help to redirect part of the liquid stream, wherein the fixing bars fix the deflector cone frustum to the bottom of the shaft, and the deflector cone frustum changes the direction of part of the stream of the two-phase charge and is provided with a number of evenly spaced apertures formed in the cone, and with a number of vertical directing elements that are located at the edge of the said deflector cone frustum and are aligned with the centres of the holes, whose role is to help direct the stream of the two-phase charge.
