MIXING AND DISTRIBUTION DEVICE COMPRISING A DISTRIBUTION PLATE WITH PERIPHERAL OPENINGS

摘要

Device for the mixing and distribution of fluids for a catalytic reactor with a downward flow, said device comprising a collection zone (A), a mixing zone (B) and a distribution zone (C) comprising a distribution plate (12) comprising at least one first zone (C1) supporting a plurality of chimneys (13) and a second zone (C2); said mixing zone (B) is comprised in an annular enclosure (15) situated in the distribution zone (C), said mixing (B) and distribution (C) zones being delimited by at least one annular wall (16) comprising at least one lateral passage section (17a, 17b) suitable for the passage of the fluids from said mixing zone (B) to the first zone (C1) of said distribution zone (C), and the second zone (C2) comprises a plurality of openings (18) suitable for the partial passage of the fluids out of the distribution zone (C).

1. Device for the mixing and distribution of fluids for a catalytic reactor with a downward flow, said device comprising:
at least one collection zone (A) comprising at least one collection means (5); at least one substantially vertical collection line (7) suitable for receiving a reaction fluid collected by said collection means (5) and at least one injection means (8) opening into said collection line (7) for injecting a quench fluid; at least one mixing zone (B), situated downstream of the collection means (5) in the direction of circulation of the fluids, said mixing zone (B) comprising at least one mixing chamber (9) connected to said collection line (7) and an outlet end (10) for removing the fluids; at least one distribution zone (C), situated downstream of said mixing zone (B) in the direction of circulation of the fluids, comprising a distribution plate (12) extending radially over the entire section of the enclosure of the reactor, said distribution plate (12) comprising at least one first zone (C1) supporting a plurality of chimneys (13) and a second zone (C2);characterized in that said mixing zone (B) is comprised in an annular enclosure (15) situated in the distribution zone (C), said mixing (B) and distribution (C) zones being delimited by at least one annular wall (16) comprising at least one lateral passage section (17a, 17b) suitable for the passage of the fluids from said mixing zone (B) to the first zone (C1) of said distribution zone (C), and in that the second zone (C2) of said distribution zone (C) comprises a plurality of openings (18) suitable for the partial passage of the fluids out of the distribution zone (C).
