Description
Technical field
The present invention relates to the use of the atomizer of petroleum refining field catalytic cracking feeds, especially a kind of heavy-oil catalytic
The application method of the feedstock oil multistage atomizing nozzle arrangements of cracking.
Background technology
At present, atomizing feed nozzle is a visual plant of petroleum refining field heavy oil catalytically cracking equipment, and it is acted on
It is：In the presence of atomizing steam, feedstock oil is crushed, atomization is substantial amounts of fine drop, then raw material oil droplet is injected to and urged
Change in cracking riser reactor, mix, react with the catalyst in riser reactor；
In the last few years, the raw material oil feeding atomizing nozzle for catalytic cracking unit, the country mainly have using secondary-atomizing
The LPC types (90209410.6) of CS types (200410010045.3), wikipedia type with steam screen, using supersonic atomization steam
The KH types (89207961.9,200420066089.3) of double wikipedia types, the BWJ types (98233035.9) with cyclone structure, tool
There are the UPC- α types (00109776.8) of porous steam distributor and the CCK types (99219391.5) with secondary-atomizing structure
Deng polytype；External similar technique then mainly has the target spray nozzle of S＆W companies, the interior of Uop Inc.'s exploitation to set porous steam point
More orifice type Optimix nozzles, Mobile companies and the interior of Kellogg companies joint development of cloth device set porous steam distributor
ATOMAX nozzles, the feed nozzle with nozzle cover that can form flat jet of ABB Lummus companies exploitation with baffle plate
And the nozzle provided with secondary-atomizing steam of Exxon companies exploitation；
However, in actual use, more or less there is following both sides in said nozzle：First, feedstock oil
Atomizing effect need further to be improved, i.e., atomized particle size is expected further to reduce；Second, atomizing steam and feedstock oil are introducing
The entrance area of nozzle influences each other, or even occurs when atomizing steam (or feedstock oil) pressure oscillation, feedstock oil (or atomization is steamed
Vapour) situation of nozzle can not be introduced.And the entrance form of feedstock oil, atomizing steam obviously has directly to these two aspects
Influence.
It is worth noting that, in above-described various nozzles, set for the entrance structure of feedstock oil, atomizing steam
Put and but show slightly simple, generally use atomizing steam along nozzle axially introduced into and feedstock oil at a certain angle from nozzle side enter
(LPC, KH, BWJ, UPC- α, CCK etc.)；Or by feedstock oil along nozzle axially introduced into and atomizing steam spray at a certain angle into
Expect nozzle (UOP, Mobile and Kellogg etc.)；Also have and feedstock oil is divided into two strands, atomizing steam is with feedstock oil along nozzle shaft
To the form (CS) of co-flow；
The classical theory of two phase flow shows, atomization process it is the most key be the broken of drop, drop is broken in steam
Broken degree is controlled by dimensionless group Weber number, have in the parameter one it is poor for the velocity of steam and drop, the numerical value is got over
Greatly, then atomizing effect is better；Feedstock oil, atomizing steam entrance area in above-mentioned various nozzles, oil, vapour two-phase are mostly with certain
Angular cross flows, and has that obvious velocity is poor, therefore will produce material impact to the overall atomizing effect of feedstock oil.
On the other hand, applicant by experimental studies have found that, in a nozzle, in feedstock oil and the entrance of atomizing steam
The introducing form of region, feedstock oil and steam " oil, vapour two-phase " serves quite crucial work to the atomizing effect of feedstock oil
With --- experimental data shows that irrational oil, vapour, which introduce form, can even make the average grain diameter of feedstock oil increase 10~30 μm
Left and right；
On the other hand, fluctuated in the catalytic cracking riser reactor feed zone of actual industrial device, operating pressure
It is unavoidable.For example, the pressure of atomizing steam is usually slightly above raw material oil pressure at this, if the oil of nozzle, vapour introduce structure not
Rationally, then feedstock oil is likely to occur to cannot be introduced into nozzle and then the situation of reactor can not be introduced --- or feedstock oil flow
It is relatively low, it can not also increase flow even if valve opening to limiting condition, that is, " oil, the vapour amount of robbing " phenomenon so-called in engineering, serious shadow occur
Ring being normally carried out for production；
A kind of 200410010045.3 patent applications that the present invention proposes for one of inventor, it is proposed that spray of multistage atomizing
Mouth (CS nozzles).By careful experimental studies have found that, the atomizing effect of this kind of nozzle ideal to the greatest extent, and in actual applications yet
There is feedstock oil flow and can not increase, be i.e. the phenomenon of " oil, the vapour amount of robbing "；In view of the foregoing, a kind of heavy oil is now invented to urge
Change the application method of the feedstock oil multistage atomizing nozzle arrangements of cracking.
The content of the invention

During use, more or less there is following both sides in the atomizer of feedstock oil：First, the atomizing effect of feedstock oil
Need further to be improved, i.e., atomized particle size is expected further to reduce；Second, atomizing steam and feedstock oil are introducing the entrance of nozzle
Region influences each other, or even occurs when atomizing steam " or feedstock oil " pressure oscillation, and feedstock oil " or atomizing steam " can not draw
Enter the situation of nozzle；And the entrance form of feedstock oil, atomizing steam obviously has direct influence to these two aspects, pass through
Rationally design, there is provided a kind of application method of the feedstock oil multistage atomizing nozzle arrangements of RFCC, enhance atomization effect
