MIXING AND DISTRIBUTION DEVICE WITH MIXING AND EXCHANGE ZONES

摘要

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), at least one mixing zone (B) comprising at least one enclosure (15) for the mixing of the fluids, at least one distribution zone (C), characterized in that said mixing zone (B) is situated at the same level as the distribution zone (C) and also comprises at least one enclosure (16) for the exchange of the fluids, connected to, and communicating with, said mixing enclosure (15), said exchange enclosure (16) comprising at least one lateral passage section (17a, 17b) suitable for the passage of the fluids from said exchange enclosure (16) to said 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 said collection line (7) in the direction of circulation of the fluids and communicating with said collection line (7), said mixing zone (B) comprising at least one enclosure for mixing the fluids (15); 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) supporting a plurality of chimneys (13); characterized in that said mixing zone (B) is situated at the same level as the distribution zone (C) and also comprises at least one enclosure (16) for the exchange of the fluids, connected to, and communicating with, said mixing enclosure (15), said exchange enclosure (16) comprising at least one lateral passage section (17a, 17b) suitable for the passage of the fluids from said exchange enclosure (16) to said distribution zone (C).
