Description
Technical field
The rotation that the present invention relates to liquid-solid mixture separation equipment technical field, specifically band rotary blade and anti-back-mixing cone divides
Device.
Background technology
At home and abroad, being on the one hand that catalytic cracking unit externally extracting oil amount increases increasingly, particularly heavy oil (or residual oil) is urged
Change cracking unit is in order to improve treating capacity, improve products distribution rule, and externally extracting oil ratio is bigger；On the other hand cycle oil
After slurry Removal of catalyst, purposes is more, added value is higher.Isolation of purified and integrated application containing agent slurry oil, it has also become petroleum refining
Important subject developing with Chemical Engineering Technology.
At present, the most existing slurry oil isolation of purified technology containing agent mainly has electrostatic separation method, tamisage, gravitational settling
Method, flocculation sedimentation, solvent extraction etc..The principle of these methods, pluses and minuses are had nothing in common with each other.Wherein settling methods is not due to
The report document needing advantage, experimental study and the commerical tests such as the separating medium such as plus high-voltage field or chemicals is more.
Though owing to having certain density contrast containing liquid-solid biphase in agent slurry oil, but difference is little, adds that slurry oil viscosity is relatively big, depend on merely
It is to be difficult to liquid-solid separation by gravity natural subsidence.Therefore, settling methods actually should refer to that centrifugation divides with eddy flow
Hypergravity isolation technics from two big classes.
Prior art still suffers from following shortcoming: 1. centrifuge separation efficiency is high, but runs up due to needs and seal
Corollary apparatus, it is impossible to operate under the conditions of high pressure (>=1MPa), high temperature (>=300 DEG C), and contain at the bottom of catalytic cracking fractionating tower tower
Agent oil-slurry pump outlet pressure and temperature are general all 0.8-1MPa, 345-365 DEG C of scope.If it is first that high pressure-temperature is oily containing agent
Slurry heat exchange cooling, after having separated also will increasing temperature and pressure again, then technological process and equipment become complicated, increase operation easier and mistake
Journey consumes energy.2. the lock out operation under the conditions of the cyclone without operating and potted component is adapted to high pressure-temperature；But due to catalysis
Agent powder particle is little, slurry oil, catalyst fines density contrast are less, cyclone tangential velocity can not be the biggest etc. multiple factors cause rotation
Stream device separation efficiency is low, it is impossible to adapt to the catalytic cracking separation requirement containing agent slurry oil.3. prove according to development and experimental study, single
Individual (level) cyclone no matter inner core insertion depth length, fluid effective rotating cycle 3-5 encloses；Inner core insertion depth is short, containing agent oil
Slurry has little time to be fully rotatable centrifugation, will discharge from inner core, low (low the most former of cyclone separation efficiency of separation efficiency
Cause)；Inner core insertion depth is long, it is desirable to can many turns of several circles, thing between the annular space in cyclone separator urceolus and outside inner core containing agent slurry oil
Number of turn-taking in reality is less, and it is downward that reason is that the circular motion between fluid annular space in cyclone separator urceolus and outside inner core makes straight line into
Motion (fluid is the flowing of short resistance little place toward path), heads direct for inner core lower edge (purification slurry oil) outlet and cone cylinder (containing agent slurry oil) goes out
Mouthful, now cyclone separator spins up the function of separation and substantially loses.If increase cyclone progression (general two-stage, most three
Level), then equipment constitutes complexity, and logistics number of share of stock (progression adds 1) increases, and flow difficulties at different levels are distributed, and separation efficiency difficulty regulates.

Solid content≤200 μ g/g in logistics (light phase).Advantage is strong adaptability；Can continuous operation.Shortcoming is the investment of equipment complex and expensive
Greatly, installation accuracy requires height；Treating capacity is little, and the difficult commercial Application that adapts to (there is presently no examples of industrial application, as Bai Zhishan etc. exists
Description (2007,34(4) in Liquid-Solid Separation Technology for Catalytic Cracking Slurry commentary: 229-232；240))；Running gear consumes energy also
Fragile, maintenance workload is big, and operating cost is high；Easily reveal, pollute the environment.
Patent of invention document CN 204815922 U, CN 104726128 A, and Bai Zhishan etc. is at catalysis externally extracting oil
Mini-hydrocyclone separation experimentation (petroleum journal (PETROLEUM PROCESSING) .2008,24(1): 229-232;240), Zhang Shirui etc. are dividing
