Background technology
Catalytic cracking be convert heavy oils into for the high value added products such as gasoline, diesel oil and oiling gas most effective technology it
One.In the industrial production of reality, the conversion ratio of heavy oil is 80-90%, that is, also 10-12% heavy oil is unconverted, is commonly called as
Catalytic slurry.Slurry oil continues freshening by catalytic cracking unit and can only obtain minimal amount of light-end products, produces more low value
Dry gas and coke, and production process is had an impact, thus without following process means refinery using slurry oil as at a low price
Fuel oil is sold.With the development of heavy-oil hydrogenation technology, in the enterprise that some have heavy-oil hydrogenation means, slurry oil passes through hydrotreating
Afterwards, petrol and diesel oil yield 1.9% can be improved by entering back into catalytic cracking unit.
Catalytic slurry is generally with a large amount of acid very strong catalyst fineses, if these powder enter weight with catalytic slurry
Oily hydrogenation reactor, serious problems, the devices such as hydrogenation catalyst area carbon, bed pressure drop rising will be caused not to transport normally
Turn.Therefore, remove catalyst fines in slurry oil and realize that catalytic slurry hydrogenation industrializes and operation must solve steadily in the long term
One of key issue.The catalyst fines that catalytic slurry carries is very thin, and conventional filtering techniques are difficult to remove.What my company developed
Catalyst fines can be reduced to 5-10 μ g/g by particular filter by 30 μ g/g, disclosure satisfy that heavy oil hydrogenation process to slurry oil
Feed needs.
In petrochemical plant, feedstock oil and catalyst occur that in high-temperature reaction process high viscosity, high rigidity can be produced
The impurity of fine particle is, it is necessary to be filtered out these impurity with filter plant, and slurry oil is not using under the conditions of just can guarantee that subsequent technique
It is impacted.Catalytic slurry filter, it is capable of washing in the case of non-stop-machine or change filter core to ensure main frame normal and continuous operation,
Therefore application commercially is more and more extensive.But when the impurity of filter interior save bit by bit it is to a certain degree and clear in time
Wash, the filter effect of filter will be influenceed, or even filter plant can be damaged.
Utility model content
In view of the above-mentioned drawbacks of the prior art, technical problem to be solved in the utility model is to provide catalytic slurry
Filter, include the pipeline of two filter vats of two identical filter vats and connection, oil inlet valve be connected between the pipeline,
Fuel-displaced valve, oil inlet, oil-out, sewage draining valve, sewage draining exit；It is provided with the filter vat and carves type V-type screen pack, top is provided with
Sealing ring and flange, bottom are provided with sump oil storage chamber；Cylinder is arranged on filter vat at the top of fire-proof and explosion-proof sealing device, gas
Between cylinder and fire-proof and explosion-proof sealing device encrypt seal sealing, the fire-proof and explosion-proof sealing device be provided with condenser pipe, fuel-displaced valve,
Oil inlet pipe and flowline；Cylinder moving axle is provided with the fire-proof and explosion-proof sealing device；The cylinder moving axle is provided with scraper plate.
Filter vat, cylinder moving axle and fire-proof and explosion-proof sealing device are on a center line.
Scraper plate is device for automatically controlling.
Type V-type screen pack is carved to be made up of into the V-type filter core of straight-tube shape vertical array.
Outwards, slot is inside for the opening of V-type filter core.
The utility model has the advantages that in the case of 250 DEG C -400 DEG C of high temperature, moving component is dual by sealing ring and flange
Protection, fire-proof and explosion-proof sealing.Impurity is stored in the sump oil storage chamber 1 of filter bottom during decontamination, catalytic powder after 5-6 times
Last impurity is discharged from the sewage draining exit of filter bottom, is only overflowed with a small amount of oil blending during discharge, can be improved oil product service efficiency.Filtering
Device integrates filtering and cleaned, and filter core recoils without immersion and without external oil collecting, time saving and energy saving, simple to operate.It is rational in infrastructure, make
With convenient, be not susceptible to failure, can long period it is practical, and repair and maintenance is convenient, service life length.
