Gas, steam or oil gas) lifting force catalyst is promoted to pipe used in eminence, be from bottom to top followed successively by pre lift zone, into
Expect section and cracking reaction area, export general setting fast separation device, react in riser to approach piston flow (laminar flow)
Mode carry out.
Riser is usually may require that before use by directly supporting installation, traditional fixation side to be fixed outside welding
Formula is time-consuming and laborious, and is not easy to the work such as later stage demolition and maintenance and replacement, and secondly, existing riser heat insulation effect is poor, instead
It should be hot a large amount of lost so that the working efficiency of riser is not high.
Utility model content
The purpose of this utility model is to solve shortcoming in the prior art, and a kind of fractionation tower top proposed follows
Ring oil riser.
To achieve these goals, the utility model employs following technical solution：A kind of fractionation tower top recycle oil is promoted
Including promoting tube body, vacuum layer is provided with, and heat preservation is provided on the outside of vacuum layer on the outside of the promotion tube body for pipe
Layer, the bottom outside of the insulating layer are fixedly connected with limited block, and be equipped with ring set, institute positioned at the outside of insulating layer on limited block
The outside for stating ring set is welded by cross bar and spacing ring, and the top of the spacing ring, which is located on the outside of vacuum layer, to be fixedly connected with
Determine ring, and the outside of retainer ring is rotatablely connected by hinge and telescopic rod.
As further describing for above-mentioned technical proposal：
The internal diameter of the ring set and the outer diameter of insulating layer are equal in magnitude.
As further describing for above-mentioned technical proposal：
The telescopic rod is provided with eight altogether, and the inside of eight telescopic rods is located in the thin bar of telescopic rod and is fixedly connected with
There is card slot.
As further describing for above-mentioned technical proposal：
The internal diameter of the card slot is equal with the diameter of spacing ring.
As further describing for above-mentioned technical proposal：
The hinge is provided with eight altogether, and eight hinges are angularly distributed along the ring heart of retainer ring.
In the utility model, first, the outside of insulating layer is equipped with retainer ring, and the outside of retainer ring pass through it is equally distributed
Hinge is rotatably connected to telescopic rod, is engaged by the card slot being fixedly connected on the inside of spacing ring and the quarter butt of telescopic rod, can limited
The corner-moving of telescopic rod, further according to the spacing of peripheral frame, the specific length of adjustable telescopic rod, so as to which riser is fixed
Stablize, this is simple in structure, easily operated, and the support that can be easily accomplished riser is fixed, and the similary dismounting work for being convenient for riser
Make, secondly, be respectively equipped with vacuum layer and insulating layer on the outside of riser, the heat generated in this way by catalytic reaction process, then
It can not dissipate outside, so as to improve the working efficiency of riser.

Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.
With reference to Fig. 1-3, a kind of fractionation tower top recycle oil riser including promoting tube body 3, promotes the outside of tube body 3
Vacuum layer 2 is provided with, and the outside of vacuum layer 2 is provided with insulating layer 1, the bottom outside of insulating layer 1 is fixedly connected with limited block
4, and ring set 5 is equipped with positioned at the outside of insulating layer 1 on limited block 4, the outside of ring set 5 is welded by cross bar and spacing ring 6, is limited
The outside that the top of ring 6 is located at vacuum layer 2 is fixedly connected with retainer ring 10, and the outside of retainer ring 10 by hinge 9 and is stretched
Bar 7 is rotatablely connected.
The internal diameter of ring set 5 and the outer diameter of insulating layer 1 are equal in magnitude, and telescopic rod 7 is provided with eight, and eight telescopic rods 7 altogether
Inside be located in the thin bar of telescopic rod 7 and be fixedly connected with card slot 8, the internal diameter of card slot 8 and the diameter phase of spacing ring 6
Deng hinge 9 is provided with eight altogether, and eight hinges 9 are angularly distributed along the ring heart of retainer ring 10.
