Description
Technical field
This utility model belongs to petroleum refining field catalytic cracking unit, relates generally to a kind of heavy-oil catalytic of multistage atomizing
Cracking novel feed nozzle.
Background technology
Reaction raw materials oil atomizing feed nozzle is a visual plant of petroleum refining field catalytic cracking unit, its effect
It is：First raw oil crushed, be atomized as substantial amounts of fine drop, then raw material oil droplet is injected to catalytic cracking riser reaction
In device, mix with the catalyst in riser reactor, react.Raw oil feed atomization spray currently used for catalytic cracking unit
The form of mouth has a lot, for example, has a cast, trunnion type, Y type, spiral blade profile, cone target type and all kinds of target type nozzle, domestic spray
Mouth has 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 raw 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 raw oil
Effect needs to be improved further；Two is that the raw 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 catalytic cracking novel atomized feed nozzle, raw oil is made to obtain multistage atomizing, effectively
Elimination major diameter drop, thus reaching the atomizing particle size required by catalytic cracking process.Research to shower nozzle finds simultaneously, spray
The raw oil that head sprays into riser reactor is contacted with catalyst, reacts insufficient, is the arrangement shape due to conventional jet expansion
Formula is unfavorable for the diffusion of raw oil, the utility model proposes four kinds of nozzle structure forms, the jet expansion center of shower nozzle both sides
Line and nozzle-axis angle are 0-30 °, and nozzle surface is deflected from middle part to both sides, is 0-30 ° with radial direction angle, this setting
Make raw material oil droplet be sprayed into from nozzle to spread to both sides after riser reactor, form broad screen, the contact surface with catalyst
Bigger.In addition, jet expansion is provided with expansion segment, through circulation area expansion segment when raw material oil droplet sprays, due to atomization gas
Density is little, and the increase with circulation area is slowed down rapidly, reduces the situation of catalyst breakage.
Utility model content
