1, because fluidized bed reactor has been set up four cyclone separators, its dipleg stretches into ebullated bed inside, when separator is worked, the gas of band catalyst is through one-level, secondary cyclone, bigger catalyst can be from the bottom Returning reactor of primary separator, a little bit smaller catalyst can be from the bottom Returning reactor of second-stage separator, therefore, the constantly catalyst of refinement circulation recovery after cyclone separator just will seethe with excitement, make catalyst constantly participate in reaction, simultaneously, because dipleg stretches in the ebullated bed, thin catalyst can not taken out of by quick air-flow yet, has prolonged the time of staying of thin catalyst in reactor.Like this, not only improve reaction efficiency, increased output, and saved catalyst.
2, because inner member changes the vertically-arranged crossbeam into and double-deck inverted V-shaped spare is staggered, sandwich construction, therefore avoided in bed, occurring the space better, make bubble evenly broken, when air-flow carries bubble through the slit that is provided with on the member, sawtooth flange, circular hole, can change fluidized state effectively, bubble crushing makes under the state that is reflected at the boiling turbulent flow and carries out better, has improved reaction efficiency.
3, because inner member adopts vertically-arranged crossbeam and inverted V-shaped structure, reduce the cross-sectional area that takies reactor to greatest extent, made catalyst be difficult for surplus sintering thereon, prevented the catalyst coking, avoided a pair reaction (unwanted product occurring).Simultaneously, because vertically-arranged crossbeam and firm connection thereof increase the intensity of inner member greatly, can prevent to damage because of the great vibrations that produces in the course of reaction, therefore, the utility model practicality is good, can be applied industrial.
