Degree, it is difficult to be processed into the problems such as powder utilizes again, bring a large amount of problems to being further processed, using and disposing.
Chinese invention patent application CN201810064280.0 proposes a kind of continuous greasy filth environment-friendly treating process utilization
Second-time burning method carries out twice combustion processing to pyrolysis waste residue and pyrolysis gas, it is therefore prevented that greasy filth may be sent out in pyrolytic process
The pyrolysis not exclusively remaining chemical substance of institute is carried out burning processing by the incomplete problem of heat solution, while to produced by greasy filth
Tail gas carry out environmental protection treatment, subsequent pollution of the discharge to environment is prevented, to substantially increase the continuous greasy filth environmental protection treatment
The using effect of technique.The problems such as this solves the final environmental protection burning processing of greasy filth, but feed system is sad in multiple
It is miscellaneous, existing feeding device can not be adapted to.
Chinese invention patent application 201410602331.2 proposes a kind of method for preparing needle-shape coke raw material, this method
Including delayed coking reaction will be carried out in the mixed raw material injection coke drum for passing through the heating of heating furnace radiant section, through the invention
Method can efficiently use the catalytic cracking dregs of fat, and reduce the green coke of process, to increase the yield of needle-shape coke raw material.But it should
Method cannot achieve the recycling of the dregs of fat, and the investment of coking processing mode is excessive.
Chinese invention patent CN00110020.3 proposes a kind of method of FCC dregs of fat catalytic cracking, this method solve
The method that each component sub-prime utilizes in the FCC dregs of fat, but method is excessively complicated, could not also solve asking for high viscosity liquid charging
Topic.
The softening temperature for how improving the dregs of fat, enabling the dregs of fat and coal, powder processed or slurrying realize resource as raw material jointly
Change clean utilization, this is urgent problem to be solved in industry.
Summary of the invention
In order to solve in the prior art the dregs of fat since oil content is high, softening point is low, it is difficult to the problem of processing powder processed, the present invention
A method of it is improved using active carbocoal containing more asphalitine dregs of fat softening point, the conduct of semicoke powder granule is matched using micron order
Packing material adds gradation semi-coke powder, is sufficiently mixed in mixer with the dregs of fat at a certain temperature, after extrusion molding,
It is crushed, fuel pulverizing plant is finally entered together with the coal that drying has been crushed and carries out dry method powder, or together with water, additive
It is added in grinding machine and carries out wet process slurrying.
To achieve the above object, the technical solution adopted by the present invention are as follows:
A method of it is improved using active carbocoal containing more asphalitine dregs of fat softening point, by preparatory grinding, the work of gradation
Property semicoke is added in the dregs of fat of melting, using mixing, active carbocoal is made sufficiently to adsorb the light components in the dregs of fat, and uniformly divide
It is dispersed in the dregs of fat, constructs effective skeletal support, the softening point temperature of the dregs of fat improves 20-50 DEG C.
A method of it is improved using active carbocoal containing more asphalitine dregs of fat softening point, comprising the following steps:
S1, gradation active carbocoal: the semicoke that average grain diameter is 50-200 μm is divided into two parts, wherein a branch is ground
Mill is prepared into the semicoke fine powder that average grain diameter is 10-40 μm, and another part is not processed；Semicoke fine powder and untreated semicoke press matter
Amount obtains gradation active carbocoal than being that 1:2-1:3 is mixed；
The modified dregs of fat of S2, semicoke: the dregs of fat being put into mixed stirring device, and be heated to 140-180 DEG C to make its melting, then
The mass ratio of the gradation active carbocoal of addition step S1, the dregs of fat and gradation active carbocoal is 1:3-2:9, carries out mixing, sufficiently mixes
It discharges after conjunction；
S3, cooling are broken: cooling be placed in crusher of material block obtained in step S2 being crushed, being crushed to partial size is
3mm material grain below；
S4, powder processed or slurrying: material grain obtained in step S3 is mixed into the coal that drying has been crushed, the quality of pellet and coal
Than being added in fuel pulverizing plant and carrying out dry method powder at normal temperature for 1:2-1:99；Or by pellet, coal together with water, additive
It is added to progress wet process slurrying in pulping device.
Preferably, the semicoke includes coal chemical industry pyrolysis char, biomass pyrolytic semicoke, oil shale pyrolysis semicoke, oil-sand
Any one or a few in asphalt pyrolysis semicoke is with the mixture of arbitrary proportion.
Preferably, the dregs of fat are that kerosene refines oil slag, the low asphalitine dregs of fat or the studies on asphaltene dregs of fat altogether；When slurry oil asphalitine
When relatively low, the pitch of makeup oil slag amount 10%-25% is needed, then when the dregs of fat are the low asphalitine dregs of fat or the studies on asphaltene dregs of fat, is needed
Want the pitch of makeup oil slag amount 10%-25%.
Preferably, in the step S1, the grinding machine that the grinding of semicoke uses is ball mill or vibrating mill.
Preferably, in the step S2, the device of mixing is mixer or the reaction kettle with reflux condensate device；
The device that the molding discharging uses is single screw extrusion machine.
Preferably, in the step S4, any one in additive NP8, NP10, SP80 modifying agent, additive
Additive amount is the 0.1%-0.5% of dregs of fat quality.
Preferably, in the step S4, it is 100- that the coal that drying has been crushed, which is by average grain diameter made from 14-40 mesh,
200 μm of coal dust.
Preferably, in the step S4, dry method powder is will to expect that grain and the coal that has been crushed of drying are placed in ball mill and grind
45-60min。
Preferably, in the step S4, wet powder-making is to be added to pellet, coal in ball mill together with water, additive
Grind 45-60min.
Compared with prior art, the invention has the following advantages:
The present invention passes through the modified modification for realizing active carbocoal, formed coke of gradation and surface first, then by modified semicoke, type
The dregs of fat of melting are added, in pitch isocolloid material in burnt particle, regulate and control the softening point of product, it is made to meet wanting for powder processed or slurrying
It asks.Present invention process is simple, significant effect, makes the softening point substantial increase of the materials such as the dregs of fat, pitch, can satisfy under room temperature
The related request of dry method powder and wet process slurrying.
By adjusting the size distribution of active carbocoal in the present invention, biggish bulk density is made it have, semicoke is passed through
The surface of grain is modified, realizes the compatible of good wellability and different attribute storeroom between the dregs of fat and active carbocoal granular boundary
Property.By the addition and mixing of the powder granules such as multi-pore micron grade semicoke, skeleton is provided for the dregs of fat or pitch colloidal materials, it will be oily
The softening point temperature of slag improves 20-50 DEG C
