Background technology
At present, in slurry reactor, gas raw material enters gas distributor by main air inlet pipe, in air inlet
In the case of pressure stability, gas will be dispersed into charging distributor pipe, and enter slurry bed system eventually by the trepanning on distributor pipe
Reactor drives the slurries (liquid and solid catalyst) in reactor to move and generation F- T synthesis is anti-under catalyst action
Should, the fluid product of generation, which is separated by filtration, leaves reactor.
But slurry reactor of the prior art, entire gas distributor are not active, lead to unstripped gas
It is unevenly distributed in the reactor, the undercompounding of gas and catalyst so that part generates high temperature, and catalyst abrasion is tight
Weight.
Invention content
The object of the present invention is to provide a kind of rotary gas feed distributor suitable for heterophase reactor, the distributors
The uniformity of gas distribution can be improved, reduces the abrasion to catalyst, improves reaction efficiency.
A kind of rotary gas feed distributor suitable for heterophase reactor, the distributor include main air inlet pipe, rotation
Adapter, tiltedly charging distribution arms, lateral nozzle and longitudinal nozzle, wherein：
The main air inlet pipe is located at the central position of the distributor, the cylinder entire distribution of structure vertical perforation
Device；
The rotary joint is located at the centre of the main air inlet pipe, and can rotate freely；
The rotary joint can remain stationary as the lower part of the main air inlet pipe, but the top of the main air inlet pipe can be freely
Rotation；
The charging distribution arms are connected and communicate with the top of the main air inlet pipe, and the oblique lateral nozzle and longitudinal direction are sprayed
Mouth is located in the charging distribution arms；
When having gas ejection in the oblique lateral nozzle and longitudinal nozzle, the gas of ejection generates thrust, described in promotion
The top of charging distribution arms and the main air inlet pipe rotates counterclockwise.
As seen from the above technical solution provided by the invention, which can improve the uniformity of gas distribution,
The abrasion to catalyst is reduced, reaction efficiency is improved, available for the F-T synthetic reactions based on paste state bed reactor.
Description of the drawings
In order to illustrate the technical solution of the embodiments of the present invention more clearly, required use in being described below to embodiment
Attached drawing be briefly described, it should be apparent that, the accompanying drawings in the following description is only some embodiments of the present invention, for this
For the those of ordinary skill in field, without creative efforts, other are can also be obtained according to these attached drawings
Attached drawing.
The structure that Fig. 1 is provided by the embodiment of the present invention suitable for the rotary gas feed distributor of heterophase reactor is shown
It is intended to；
The side that Fig. 2 is provided by the embodiment of the present invention suitable for the rotary gas feed distributor of heterophase reactor shows
It is intended to.
Specific embodiment
With reference to the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Ground describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.Based on this
The embodiment of invention, the every other implementation that those of ordinary skill in the art are obtained without making creative work
Example, belongs to protection scope of the present invention.
The embodiment of the present invention is described in further detail below in conjunction with attached drawing, is implemented as shown in Figure 1 for the present invention
Example provides suitable for heterophase reactor rotary gas feed distributor structure diagram, the distributor including lead into
Tracheae 1, rotary joint 2, tiltedly charging distribution arms 3, lateral nozzle 4 and longitudinal nozzle 5, wherein：
The main air inlet pipe 1 is located at the central position of the distributor, the cylinder entire distribution of structure vertical perforation
Device；
The rotary joint 2 is located at the centre of the main air inlet pipe 1, and the effect of the rotary joint 2 is can be in inside
Under conditions of having liquid medium, and it can rotate freely；
The rotary joint 2 can remain stationary as the lower part of the main air inlet pipe 1, but the top energy of the main air inlet pipe 1
It rotates freely；
The charging distribution arms 3 are connected and communicate with the top of the main air inlet pipe 1, the oblique lateral nozzle 4 and indulge
It is located in the charging distribution arms 3 to nozzle 5；
When having gas ejection in the oblique lateral nozzle 4 and longitudinal nozzle 5, the gas of ejection generates thrust, pushes institute
The top for stating charging distribution arms 3 and the main air inlet pipe 1 rotates counterclockwise.
In addition, charging distribution arms is pushed to rotate using the unstrpped gas that tiltedly lateral nozzle 4 is discharged, so as to drive charging point
After cloth branch pipe 3 and its exhaust outlet rotation, unstripped gas is more uniform from exhaust outlet discharge distribution, so as to make the mixed of gas and catalyst
Conjunction is more abundant, the problem of improving reaction efficiency, avoid hot-spot, alleviates the abrasion of catalyst.
In the specific implementation, the upper connection of the distributor uses self sealing structure, and use stainless steel or engineering plastics
It makes.
The side schematic view of the gas feed distributor is illustrated in figure 2, as can be seen from Figure：The tiltedly gas of transverse direction nozzle 4
Body injection direction is 45 degree of obliquely downward of horizontal direction, and the gas injection direction of longitudinal nozzle 5 is vertical downward direction.
