Description
Technical field
The present invention relates to petrochemical equipment field, particularly a kind of cycle oil sizing device externally extracting oil filter plant.
Background technology
The externally extracting oil of catalytic cracking unit be in refinery catalytic cracking unit in production process cannot the tailing of cracking, by the form discharger of " getting rid of outward ".Due to catalytic cracking unit use fluidized-bed reaction, in externally extracting oil can not avoid containing solid catalyst powder, powder is mainly aluminium oxide or silicon dioxide, and solids content is 3000-20000ppm.The most typically in terms of the solids treatment of externally extracting oil, only settle and filter two kinds of methods, for using filtering technique, be the most all the filter system using and there is backwashing function.Namely in normal filtration work process, the slurry oil containing solid particle will flow to another side from the one side of filtering material under pressure differential effect, and solid particle is just trapped within the surface of filtering material, form filter cake.Along with the prolongation of filtration time, being accumulated in the filter cake thickness on filtering material surface can increase, and produces input and output material pressure reduction.When pressure reduction reaches setting value or filtration time reaches setting value, and filter will stop charging, reversely pressurizes, quickly opening the slag-discharging valve of feed side, the liquid in filter can produce the reverse flow of explosion, and filter cake is pushed away filtering material, from slag-drip opening outflow filter, complete backwash.Filter feeds again, carries out the filter process in next cycle.
The filtering technique of existing externally extracting oil cannot meet the needs that macrocyclic filtration continuously runs, and externally extracting oil filtering device system used carries out the time and typically just blocked within 3 months.Reason be domestic catalytic cracked oil pulp be all residue than the highest heavy oil catalytically cracking equipment, asphalt content in the externally extracting oil of such catalytic cracking unit is the highest, the different bitumen contents in the externally extracting oil in catalytic cracking unit and the feedstock property of device, operational circumstances are relevant, different, typically at 1-5%.These asphalitine compositions, neither solid, are not liquid, belong to colloid, if the filtering material of asphalitine, and produce deformation, it is impossible to by the way of backwash, it is separated with filtering material.And adhere to inside filtering material, cause filter element to block, it is impossible to backwash regenerates.Make the whole filtration system will be blocked in the comparatively short time, it is impossible to backwash regenerates, make the whole filtration cannot long time running.
Summary of the invention
Present invention aim to overcome that the deficiencies in the prior art, it is provided that a kind of filtration integrated equipment of catalytic cracked oil pulp fractional distillation, by arranging rational structure, improve equipment to slurry oil filter efficiency, reduction material consumption and energy consumption, it is achieved energy-conserving and environment-protective.
To achieve these goals, the technical scheme that patent of the present invention uses: a kind of cycle oil sizing device externally extracting oil filter plant, this filter plant includes housing 1, filter screen 7, flushing liquor entrance 2, sludge outlet 9, slurry oil entrance 10, slurry oil outlet 5, this filter plant also includes ultrasonic module 6, piston rod 4, wheel blade 8, described filter screen is from groove structure, it is positioned at housing 1 internal, contacted with housing two side by movable slide block 11, piston rod 4 penetrates in equipment from case top, extend through the bottom portion of groove of filter screen 7, piston rod 4 is provided with wheel blade 8 through bottom portion of groove one end, ultrasonic module 6 is positioned on movable slide block 11.
Further illustrating as the present invention, the number of described ultrasonic module 6 is more than 2.
Further illustrating as the present invention, described filter screen 7 filter membrane material is ceramic membrane filter screen or metal film filter screen.
Further illustrating as the present invention, described piston rod 4 is positioned on the one end outside housing 1 piston handle 3.
Further illustrating as the present invention, described piston rod 4 passes filter screen 7 by soldering opening 7-1.
Present device is in use, the slurry oil got rid of outward flows into from slurry oil entrance 10, the slurry oil flowed into immerses filter screen 7, from slurry oil outlet 5 outflow, in slurry oil, dregs of fat granule sinks to device bottom, in filter process, piston rod 4 can move up and down by band electric filter 7, device interior slurry oil is formed certain pressure, thus accelerate filter efficiency, when the dregs of fat amount of device interior reaches some (when slurry oil entrance slurry oil flow velocity is slow, illustrate that the dregs of fat are too much), open dregs of fat outlet and slurry oil is discharged.When equipment inner filtration efficiency is low, when needing filter screen is carried out, slurry oil entrance is closed, utilize vacuum pump to be detached from slurry oil outlet by slurry oil, close slurry oil outlet, flushing liquor entrance is opened, pour into flushing liquor, make flushing liquor all not have drainage screen, open ultrasonic module and carry out ultrasonic 30-120min, then pressurize from flushing liquor entrance, when pressure is increased to a certain degree (about 1.5MPa), close flushing liquor entrance, open dregs of fat entrance with the fastest speed, flushing liquor is discharged.
Beneficial effects of the present invention:
1.
The present invention is by design groove filter structure and arranges ultrasonic module structure, overcoming slurry oil studies on asphaltene colloid composition makes filter screen produce deformation, itself and filtering material separation problem cannot be made by the way of simple backwash, filter plant reasonable in design, filter efficiency is improved, and the slurry oil particulate matter removal effect after filtration is good.
2.
Result of the present invention is simple, uses conveniently, safely, scientific and reasonable, it is simple to promote the use of.
