Distributor nozzle for a two-phase charge in fixed-bed reactors

The invention relates to a distributor nozzle (10, 20, 30, 40 and 50) for a two-phase charge, to be used in fixed-bed reactors in order to increase the area over which the mixture is dispersed and to make its flow rate the same over the whole area of the bed in the reactor. The device can consist of...

Beschreibung
Zusammenfassung:	The invention relates to a distributor nozzle (10, 20, 30, 40 and 50) for a two-phase charge, to be used in fixed-bed reactors in order to increase the area over which the mixture is dispersed and to make its flow rate the same over the whole area of the bed in the reactor. The device can consist of the following basic parts: a number of fixing bars and a deflector cone frustum. In the preferred embodiment, the deflector cones or cone frusta (14, 24, 34, 44 and 54) may have more than one angle in order to improve the distribution, and they have a number of apertures (12, 22 and 46) or slits (36) and a number of vertical directing elements (16 and 26) or a directing cage or frame (55) to direct the stream of the two-phase charge in order to increase the area over which the mixture is dispersed and to make its flow rate the same over the entire area of the bed in the reactor.
