Description
Technical field
The utility model belongs to petroleum refining field catalytic cracking unit, relates generally to a kind of catalytic cracking of multistage atomizing
Feed nozzle.
Background technology
Raw material oil feeding atomizing nozzle is a visual plant of petroleum refining field catalytic cracking unit, and its effect is:
First feedstock oil crushed, be atomized as substantial amounts of fine drop, then raw material oil droplet is injected to catalytic cracking riser reactor
In, mix with the catalyst in riser reactor, react.Raw material oil feeding atomizing nozzle currently used for catalytic cracking unit
Form have a lot, for example, have cast, trunnion type, Y type, spiral blade profile, cone target type and all kinds of target type nozzle, domestic nozzle
There is single-tube nozzle, that is, adopt single tube chamber to feed air inlet mixed aerosol, using effect is less desirable.
Nozzle make reaction raw materials become droplet it is therefore an objective to can Quick-gasifying reacting, atomization is not final purpose,
Improve reaction effect and be only target.For the reaction result having reached, that is, need to make the liquid atomization, need to make atomization logistics again
Distribute in reactor, be critically important especially with catalyst uniform contact.
Further, since the liquid mist such as feedstock oil to be made turns to fine particle, need higher pressure drop and gas flow rate.Existing
The gas-liquid atomization logistics of technology high speed is injected directly into reactor, catalyst is washed away broken more serious.
But in actual use, said nozzle more or less has problems with:One is the atomization of feedstock oil
Effect needs to be improved further;Two is that the feedstock oil being injected in riser reactor by nozzle is not wide with catalyst contact surface,
Reaction effect is not good;Three be the atomization having nozzle to spray raw material oil droplet jet velocity too high, make catalyst breakage serious.
The utility model proposes a kind of multistage atomizing feed nozzle, make feedstock oil obtain level Four atomization, effectively eliminate big
Diameter droplets, thus reach the atomizing particle size required by catalytic cracking process.Research to shower nozzle finds, shower nozzle sprays into and carries simultaneously
The feedstock oil of riser reactors is contacted with catalyst, reacts insufficient, is because the arrangement form of conventional jet expansion is unfavorable for
The expansion of feedstock oil, the utility model proposes four kinds of nozzle structure forms, the jet expansion center line of shower nozzle both sides and nozzle
Axis angle is 0-30 °, and nozzle surface is deflected from middle part to both sides, is 0-30 ° with radial direction angle, this setting makes feedstock oil
Drip to be sprayed into from nozzle and expand to both sides after riser reactor, form broad screen, bigger with the contact surface of catalyst.Separately
Outward, jet expansion is provided with expansion segment, through circulation area expansion segment when raw material oil droplet sprays, because atomization gas density is little,
Increase with circulation area is slowed down rapidly, reduces the situation of catalyst breakage.
Utility model content
