In order to make those skilled in the art more fully understand technical solution provided by the invention, below in conjunction with attached drawing and
The present invention is described in further detail for specific embodiment.
As shown in Figure 1, a kind of feed nozzle of catalytic cracking provided in an embodiment of the present invention, including nozzle body, nozzle
The side of ontology is provided with distributor 1 and nozzle 2, and the first trepanning 3 for disperseing fluid, distributor 1 are provided on distributor 1
It is provided with ultrasonic atomization chamber 4 between nozzle 2, and the first trepanning 3 on distributor 1 is connected to ultrasonic atomization cavity 4, surpasses
It is provided with the ultrasonic generator 5 for generating Sasser in sound wave atomization chamber 4, and then is sprayed by the first trepanning of distributor
The fluid gone out can be further atomized by ultrasonic atomization cavity, then be sprayed by nozzle 2.
What needs to be explained here is that those skilled in the art will readily appreciate that, the work of general feed nozzle
Flow is that fluid enters nozzle body, after distributor disperses, is sprayed by nozzle.Compared to traditional feed nozzle, it is above-mentioned to urge
Change the feed nozzle of cracking, the fluid sprayed to distributor by ultrasonic horn is atomized, with traditional barber
Change compared to 90% or more energy consumption can be reduced, avoid steam-heated thermal energy or other supplementary energies, effectively reduce the energy consumption,
Reduce the operating cost of equipment.In addition pass through increase supersonic atomizer so that fluid destroyed in atomization process by
Atomizing medium intermolecular association, thus also have the effects that increase reaction depth, improve reaction effect.
It, can also be in the position of corresponding first trepanning 3 on above-mentioned ultrasonic horn in some specific embodiments
Install the second trepanning 6.The fluid for passing through the first trepanning dispersion on distributor in this way, faces the second trepanning and is sprayed,
Impact velocity is relatively fast, and when ultrasonic generator sends out high frequency oscillation, the atomizing effect of the fluid through the second trepanning is more
It is good.It is appreciated of course that it is only the one of the embodiment of the present invention that the position of 3 and second trepanning 6 of above-mentioned first trepanning is corresponding
Kind is preferably illustrated, and can also be not corresponding setting, only present invention preferably employs the modes being correspondingly arranged.
In some more particular embodiments, the quantity of above-mentioned first trepanning 3 is preferably several, by opening up multiple open
Hole so that fluid is more preferable by the atomizing effect after the first trepanning, it is of course possible to which understanding is the quantity that can also be the first trepanning
It it is 1, for example slotted hole etc. is opened up along the circumferential direction of distributor, only the embodiment of the present invention preferably uses the first trepanning
Quantity is multiple forms.
And the first being arranged circumferentially along distributor 1 of trepanning 3, so that after the first trepanning of distributor
The atomization of fluid is more uniform, and effect is more preferable.Certainly it according to actual demand, can also be arranged using mode heterogeneous.
More specifically, above-mentioned first trepanning 3 can open up into straight hole, can also open up into shrinkage hole, expanded bore can also be opened up into, or

In a further embodiment, the quantity of the spray orifice 7 opened up on above-mentioned nozzle 2 can also be multiple.Certainly
Can open up into one according to actual demand, only the embodiment of the present invention preferably uses and sets the nozzle hole number of nozzle to
Multiple forms, each spray orifice outlet mist shape are expansion taper, whole atomization mass are formed after porous combination, and spray orifice 7 is along nozzle 2
Be arranged circumferentially because in this way by nozzle fluid atomizing effect more preferably.
In some more particular embodiments, the feed nozzle of catalytic cracking provided by the invention, which can also be, to be integrated in
On the basis of original steam atomization nozzle, so that realizing repeatedly atomization by the fluid of feed nozzle, atomizing effect is more
It is good.Nozzle body should also include oil inlet pipe 8 and be set in the outer tube 9 in the outside of oil inlet pipe 8, oil inlet pipe 8 and housing at this time
The cavity constituted between pipe 9 is steam atomization cavity;Of course for avoiding fluid from leaking, oil inlet pipe is close to inlet side and housing
The end side of pipe should be provided with sealing element, for example blanking cover 13 is sealed, and blanking cover can be threadedly coupled mode and be fixed on housing
Guan Shang.The ostium 11 for entering steam atomization cavity for fluid is provided on oil inlet pipe 8;Be provided on outer tube 9 for
Steam atomization cavity imports the air inlet pipe 10 of steam;Steam atomization cavity is communicated with the first trepanning 3.
In order to which those skilled in the art are better understood from the spray of the charging on the basis of being integrated in original steam atomization nozzle
Mouth is illustrated with reference to specific atomization process:
Feedstock oil enters oil inlet pipe by raw material oil-in, steam atomization cavity is injected by inflow entrance, by air inlet
The steam that pipe enters steam atomization cavity accelerates realization atomization for the first time after atomization;Feedstock oil after primary atomization is passing through distribution
After circumferential first trepanning sprays on device, realizes second and be atomized;Feedstock oil after secondary-atomizing is in ultrasonic atomization
Intracavitary by Sasser that ultrasonic generator generates spray through nozzle after third time atomization.
In further embodiment, the driving device 12 of above-mentioned ultrasonic generator 5 is arranged in nozzle body
Outside, can also be provided in the inside of nozzle body according to actual demand certainly, only be arranged more square in disposed outside
Just.And driving device 12 can also be connected with the control device of frequency and power for adjusting ultrasonic wave.And then specific
