Abstract
The invention relates to a novel flushing-resistant air cushion elbow. The novel flushing-resistant air cushion elbow comprises a pipe type reactor wall, a high-wear-resistant lining, a checking hand hole and a blind pipe, wherein the pipe type reactor wall and the blind pipe are integrally molded; the blind pipe is positioned on the most upper place of the flushing-resistant air cushion elbow facing a medium inlet; the end of the blind pipe is arc; the high-wear-resistant lining is positioned on the inner surface of the pipe type reactor wall; the checking hand hole is fixed to the pipe type reactor wall opposite to a medium outlet. By the technical scheme provided by the invention, the wear resistance can be effectively improved, and the service life can be effectively prolonged.
Description
Technical field
The present invention relates to the air cushion elbow of petrochemical industry, particularly relate to a kind of novel resistance to erosion air cushion elbow.
Background technique
Catalytic cracking technology is the technology generally adopting in oil refining industry.The a large amount of heavy oil residues (accounting for feedstock oil more than 60%) that produce in petroleum refining time processing process can be converted into the gasoline, diesel oil and the petroleum gas that in national economy, need in a large number by this technology.
At present in catalytic cracking technology, the process such as the catalytic pyrolysis of oil product and the regeneration of catalyzer is all carried out in fluidized bed under fluidized state.On catalytic cracking fluidized bed plant, carry in the pipeline and tubular reactor of catalyzer, working medium is for containing high concentration catalyst (>=50kg/m
3), the high-temperature oil gas of high-speed (18～20m/s).This containing high concentration catalyst, high-speed gas stream is quite severe to the erosive wear of pipeline wall in course of conveying.The position of particularly turning at pipeline.Fig. 1 is the elbow of pipeline of existing known conveying catalyzer, and it is to adopt 90 degree blade bends.The elbow of this structure just to MEDIA FLOW to wall on, because medium continuously washes away at a high speed, often worn out, cause high-temperature oil gas to leak, even catch fire, initiation fire.Production cannot normally be carried out, and is forced to shut-down (breakdown) mainteance.
Because the disadvantage that above-mentioned existing air cushion elbow exists need to be changed the air cushion elbow structure of design in the past.Practical experience and the professional knowledge of the inventor based on being engaged in this type of product specification manufacture and enriching for many years, and coordinating the utilization of scientific principle, actively research and innovation in addition, to founding a kind of novel resistance to erosion air cushion elbow, can improve general existing air cushion elbow, make it have more practicability.Through constantly research, design, and after repeatedly studying sample and improving, finally create the present invention who has practical value.
Summary of the invention
For solving the problem of above-mentioned existence, the object of the present invention is to provide a kind of resistance to erosion air cushion elbow of new structure, its media-resistant stream abrasion resistance properties under bad working environments is improved greatly, greatly extend working life, thereby more applicable.
The object of the invention to solve the technical problems is to adopt following technological scheme to realize.A kind of novel resistance to erosion air cushion elbow proposing according to the present invention, comprising: tubular reactor wall, high abrasion lining, inspection hand hole, blind pipe; Wherein this tubular reactor wall and blind pipe are formed in one, blind pipe is positioned at the top of this resistance to erosion air cushion elbow relative with medium inlet, high abrasion lining is positioned at the internal surface of this tubular reactor wall, checks that hand hole is fixed on the tubular reactor wall of opposing side of media outlet.
Object of the present invention and solve its technical problem and can also be further achieved by the following technical measures.
Aforesaid a kind of novel resistance to erosion air cushion elbow, wherein the termination of blind pipe is circular arc.
By technique scheme, a kind of novel resistance to erosion air cushion elbow of the present invention at least has the polishing machine of raising and the advantage such as increase the service life.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of specification, and for above and other object of the present invention, feature and advantage can be become apparent, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.
Accompanying drawing explanation
Fig. 1 is the structural representation of the elbow of pipeline of existing known conveying catalyzer.
Fig. 2 is the structural representation of a kind of novel resistance to erosion air cushion elbow of the present invention.

Embodiment
Technological means and effect of taking for reaching predetermined goal of the invention for further setting forth the present invention, below in conjunction with accompanying drawing and preferred embodiment, to a kind of novel its embodiment of resistance to erosion air cushion elbow, structure, feature and effect thereof of proposing according to the present invention, be described in detail as follows.
Fig. 2 is the structural representation of a kind of novel resistance to erosion air cushion elbow of the present invention.As shown in Figure 2, a kind of novel resistance to erosion air cushion elbow of the present invention, comprising: tubular reactor wall 1, high abrasion lining 2, inspection hand hole 3, blind pipe 4; Wherein this tubular reactor wall 1 is formed in one with blind pipe 4, blind pipe 4 is positioned at the top of this resistance to erosion air cushion elbow relative with medium inlet, and the termination of blind pipe 4 is circular arc, high abrasion lining 2 is positioned at the internal surface of this tubular reactor wall 1, checks that hand hole 3 is fixed on the tubular reactor wall 1 of opposing side of media outlet.
Object of the present invention adopts following scheme to realize:
The air cushion elbow of novel resistance to erosion is that the position that 90 on original pipeline degree blade bend is faced to MEDIA FLOW increases by one section of blind pipe 4 as an air cushion, as shown in Figure 2.When the high speed flowing at the catalyst media of high flow rate, high concentration, high wearing and tearing is like this washed away, wash away very severe to facing the internal surface of MEDIA FLOW entrance, owing to just the gas in one of MEDIA FLOW section of blind pipe 4 being played to air cushion buffering buffer action, the destruction of its erosive wear reduces greatly.Make so greatly improve the working life of air cushion elbow.Be widely used at present and transported the corner that catalyzer pipeline turns to, as the upper elbow of riser reactor, resistance to erosion abrasive effect is very good.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, although the present invention discloses as above with preferred embodiment, but not in order to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, when can utilizing the technology contents of above-mentioned announcement to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be the content that does not depart from technical solution of the present invention, foundation technical spirit of the present invention is to any simple modification made for any of the above embodiments, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
