Background technology
Existing fast bed revivifier, reclaimable catalyst, external warmer return cold catalyzer and the cycling hot catalyzer all is to get into fast bed from burning side, a jar bottom (wall opening), does not have the catalyst distribution facility.It is inhomogeneous that this mode of entrance causes burning jar lower section density of catalyst, and especially carbon-bearing reclaimable catalyst skewness will directly influence regeneration effect.The cold catalyzer that returns of external warmer gets into from burning jar bottom in addition, makes to burn jar temperature of lower and reduce, and scorching speed is reduced.
The CN2848348Y utility model has been developed solid dielectric sparger in a kind of fine powder fluidizing reactor; It is made up of 1 horizontal inlet house steward and 2 horizontal branch pipees; The level pipe below is provided with several powder outlets; And below level pipe, being provided with the fluidized wind facility, a jar cross-sectional distribution catalyzer is being burnt in attempt.Catalyzer powder characteristic is a very difficulty of horizontal feed, so this sparger is very difficult even in the fluidized-bed cross-sectional distribution with the catalyzer powder.
Summary of the invention
The utility model solves the technical scheme that its technical problem adopted: a kind of fast bed highly efficient regeneration modifying device; Comprise main feedline, main allocated equipment, auxiliary duct, main allocated equipment and auxiliary divider; The main feedline bottom is connected with reclaimable catalyst pipe lower end and circulation tube lower end, and top is connected with main allocated equipment; The auxiliary duct bottom is connected with the cold catalyst tube lower end that external warmer comes, and top is connected with auxiliary divider; Auxiliary dispenser arrangement is above main allocated equipment; Main feedline and main allocated equipment delivery profile reclaimable catalyst and cycling hot catalyzer, the cold catalyzer that auxiliary duct and auxiliary divider delivery profile external warmer come.
The said main and auxiliary transfer lime aspect ratio that helps is 0.5～10, and main feedline is a sleeve structure, or a transfer lime independently, and main feedline and auxiliary duct bottom all are provided with carries wind inlet or endless tube.
Said main allocated equipment is 0.2～6m above revivifier main air sparger, auxiliary divider 1～10m above main allocated equipment.
The said main and auxiliary divider that helps is tubular divider, or the flute profile divider, or the dendroid divider.
Said main feedline and auxiliary duct can be merged into 1 total transfer lime, and main allocated equipment and auxiliary divider can be merged into 1 total points orchestration.
Said total transfer lime is a straight tube, or bottom enlarged structure, total transfer lime set inside spiral guide vane or grid baffle plate or be not provided with.
Said total points orchestration is located at the below or the top 0～2m of revivifier main air sparger, and the total points orchestration is designed at the top of transfer lime and a plurality of wear-resisting holes or wear resistant short tube are opened in the side, or/and connect many wear-resisting conveying arms.
Said reclaimable catalyst pipe is connected at the outside and total transfer lime of revivifier, or passes wall on revivifier top and enter into internal regenerator and be connected with total transfer lime.
The utility model advantage and positively effect are: with being transported to fast bed bottom and uniform distribution after reclaimable catalyst and the cycling hot catalyst mix; The cold catalyst transport of simultaneously external warmer being discharged is in the middle part of fast bed and be evenly distributed; This being designed with is beneficial to raising fast bed temperature of lower, helps improving the fast bed scorching speed.
