Fig. 1 is flow chart of the invention.
Specific embodiment
A kind of production method of cable inner shield material carbon black:
Air after inputting combustion gas and from preheating to the burning zone of reacting furnace, air are forced by multiple centrifugal fan
90kPa~100kPa is simultaneously delivered in reacting furnace after being preheating to 700 DEG C~780 DEG C；Natural gas low heat valve is 8200kcal/
m3, it is delivered in reacting furnace with pressure for 100kPa~110kPa, wherein air and the volume ratio of combustion gas are 16:1~17:1, combustion
The ignition temperature for burning section reaches 1850 DEG C~1900 DEG C, and the flue gas flow rate that burning zone generates reaches 120m/s~150m/s；Combustion gas
Burning provide hot environment and energy for the cracking reaction of subsequent carbolineum；
Be pumped into the trunnion section of reacting furnace and be preheating to 180 DEG C of carbolineum, the flow control of carbolineum 3500kg/h~
4200kg/h, carbolineum quality index are as follows: the density p 20 when mass ratio≤0.2% of toluene insolubles, 20 DEG C is 1.13g/cm3
~1.15g/cm3, viscosity E80≤2, water volume than fraction≤1% before≤1%, 210 DEG C, the fraction before 360 DEG C >=
60%.Carbolineum is extracted from coal tar, and the boiling range section that carbolineum obtains is 270 DEG C to 360 DEG C.Carbolineum passes through standing sedimentation, then
The impurity in deoiling is removed after filtering by basket filter, 3.0MPa~3.5MPa is forced by rotary jet pump, with flow
It is delivered to tubular heat exchanger for 3500kg/h~4200kg/h, carbolineum passes through ten after being heated to 180 DEG C in tubular heat exchanger
Atomizing lance radially sprays into reacting furnace in trunnion section along reacting furnace.The high-temperature flue gas that burning zone generates forms carbolineum mist and shears
It acts on and provides hot environment, energy for the cracking reaction of carbolineum, high speed, high temperature keep carbon black cracking partial size small, when extending reaction
Between and improve temperature and can increase carbon black collision opportunity, make that carbon black particle superficial layer is coarse, surface-active is big, resistance it is low and easily with
Rubber and plastic hybrid process.
In addition, conductive black is higher to product requirement on electric performance, and the potassium, sodium ions content in carbolineum are to the structure of carbon black
Degree is affected.Therefore it can be by potassium, sodium ions content in control feedstock oil, to guarantee the high degree of structuration of carbon black.Production of carbon black is used
Potassium content in carbolineum is 0.5ppm~1ppm, sodium ions content is 1ppm~1.5ppm.It is raw using Japanese Shimadzu Corporation
The AA-6880 atomic absorption spectrophotometer of production measures, and then reaches the requirement of electric conductivity.
The reaction that cold water terminates carbolineum under hot environment is sprayed into the quench zone of reacting furnace, the control of carbolineum reaction time exists
0.2s~0.3s generates powdered carbon black after reaction.Cold water not only terminates the cracking reaction of carbolineum, while also preliminary to high-temperature flue gas
Cooling makees place mat for subsequent technique.
Then the high-temperature flue gas that carry powdered carbon black of autoreaction furnace output cools down through heat-exchanger rig considers in device in fact in bag
Existing powdered carbon black is collected with tail gas separation and by powdered carbon black, and the powdered carbon black after collection is defeated through conveyance conduit by blower
It send to burgy storage tank, is equipped with micron disintegrator on conveyance conduit, the impurity in powdered carbon black is ground into micro- in micron disintegrator
The other powder of meter level.
Further include granulating working procedure, in granulating working procedure, the powdered carbon black being stored in burgy storage tank is delivered to pelletizer
It is granulated；Need to add binder in granulation process into pelletizer, it is 18% that the binder, which is according to weight percent,
The maltose solution configured.For maltose compared with other binders, ash content is low, and degree of purity is high, ash content 0.06%.It is defeated
The flow for sending the metering pump of binder is 100kg/h, and the flow for being granulated water pump is 6m3/h.Binder is before being added to pelletizer
By mixed processes, in mixed processes, binder is added by metering pump from the import for being granulated water pump, through the leaf for being granulated water pump
Binder is tentatively mixed with water is granulated under wheel agitaion；Preliminary mixed binder and granulation water, which are transported to be located at, to be granulated
The static mixer of machine entrance further mixes.
Water used in granulation water added by cold water that the quench zone of reacting furnace sprays into, pelletizer and configuration binder passes through
Cross purification process technique, purification process technique the following steps are included:
Step 1: the large granular impurity in water is removed using more medium filter；
Step 2, the water that step 1 is obtained remove peculiar smell, organic impurities in water by active carbon filter；
Step 3: the water that step 2 is obtained removes the salt ion in water by RO reverse osmosis membrane；
Step 4: the water that step 3 is obtained passes through the further desalination of Na-ion exchanger, and making that treated, the water hardness makes
The water hardness that treated is 0~4.5mg/L, and the optimal water hardness is 0；The conductivity of water≤0.2 μ s/cm.
Being granulated carbon black products also needs to guarantee the degree of purity of carbon black by screening, except magnetic etc. is refining to obtain final products.Screening
It is existing screening machine in application market, the screening of particle is carried out by its internal screen, the carbon black pellet of bulk is sifted out to come.
Except magnetic is then to be removed the ferromagnetic material that equipment attrition mixed in carbon black and equipment are corroded with magnetic separator, traditional magnetic separator
Inside is permanent magnet, as time long magnetic meeting is weak, can also be decayed under high temperature environment.Therefore preferred electromagnetic equipment, passes through
Coil generates Induced magnetic field, and magnetic flux can reach the 12000Gs intensity that permanent magnet is unable to reach, and will not increase because of service life
And decay, decaying will not be accelerated because temperature increases.
