Description
Technical field
The present invention relates to a kind of titanium slag electric furnace dust-removing powder recoverying and utilizing method, particularly a kind of chemical industry metallurgical field that is related to
Titanium slag electric furnace dust-removing powder recoverying and utilizing method.
Background technology
Chinese Titanium resource reserve enriches, and main grouping is in Panzhihua-Xichang Region.The storage of Panxi Diqu titanium resource is verified at present
Amount accounts for the 35.7% of world resource, accounts for the 90.5% of Chinese proved reserves.But it is containing the low-grade of high contents of calcium and magnesium to climb western ilmenite concentrate
Primary ilmenitite ore deposit, it is solid containing oxide impurities such as magnesium, manganese, aluminium, vanadium, silicon based on metatitanic acid iron (FeOTiO2) lattice
Solution.
Panzhihua ilmenite concentrate system climbs western vanadium titano-magnetite and first selected selects ilmenite concentrate again after iron ore concentrate, for lifting iron concentrate grade
With ilmenite concentrate yield, titanium selecting art is changed to " strong magnetic by former " high intensity magnetic separation~gravity treatment~flotation~electric separation " flow in the prior art
~ore grinding~strong magnetic~flotation ", but bring ilmenite concentrate overall particle size to attenuate therewith, certain influence is brought to application, for large-scale
Smelting titanium slag with electric stove, is safeguards system direct motion and titanium slag yield, passes through theoretical calculation and practical proof, it is desirable to >=0.09mm titaniums essence
Ore deposit is directly entered electric furnace smelting, and≤0.09mm ilmenite concentrate pelletizings fed to boiler is smelted.Show that prior art is produced from actual count
Ilmenite concentrate size distribution it is wide, it is overall partially thin.Typically directly enter stove smelting titanium slag for prior art production 10# ilmenite concentrates, but
Because of it in smelting process<0074mm ratios are laid particular stress on, and cause part fine granular materials in furnace gas and dedusting during charging
Enter dust pelletizing system with tail gas under fan action, produce dust-removing powder, be particularly the feelings for containing more fine powder material in the raw material of stove
Under condition, the dust-removing powder amount of generation is bigger.Although the useful component produced in dedusting ash containing titanium slag, is due to dedusting ash grade
Relatively low and granularity is very thin, there is presently no good utilization method, it will usually throws aside the rubbish in industrial park as discarded object
In, 5000-6000 tons of dedusting ash is thrown aside in appointment greatly every year for a large-scale titanium slag manufacturing enterprise, not only causes the wasting of resources,
And also need to pay the waste disposal fee of great number.
The content of the invention
Simple the invention provides a kind of technique, efficiency high, cost is low, environmental protection, and the titanium that can now mass produce
Slag electric stove dust powder recoverying and utilizing method.
Titanium slag electric furnace dust-removing powder recoverying and utilizing method of the invention to solve the above problems used, including following step
Suddenly：
A, the addition water formation slurry into titanium slag electric furnace dust-removing powder；
B, to slurry carry out magnetic separation separation, formed ilmenite concentrate；
C, ilmenite concentrate slurry after magnetic separation is filtered, its moisture is less than 15%；
D, magnetic separation is obtained ilmenite concentrate carry out pelletizing processing；
E, the pelletizing made add smelting titanium slag with electric stove after being dried.
Be further, in step A keep slurry in solid content 20%~35%.
It is further that magnetic field intensity control is in the range of 0.2T~0.8T in step B.
It is further that ilmenite concentrate slurry after magnetic separation is filtered using the method for vacuum filtration in step C.
It is further that ilmenite concentrate slurry after magnetic separation is filtered using the method for press filtration in step C.
Be further, in D steps by filtering after ilmenite concentrate with add in fine fraction ilmenite concentrate raw material carry out it is just mixed, according to
Secondary addition bonding agent and water, control mix up material moisture 5%~8%.
It is further to cause the pelletizing diameter control being made in 5mm~15mm, compression strength of green pel let control in D steps
System is in more than 700N.
It is further, the action of forced stirring during step A adds water.
It is further that pelletizing is smelted using electric furnace high-temperature tail gas in E steps.
The beneficial effects of the invention are as follows：It is right using the present processes it is possible to prevente effectively from dust-removing powder airborne dust, environment-friendly
Skill is sorted after titanium slag electric furnace dust-removing powder humidification, the efficiency of separation is high, obtains fine fraction ilmenite concentrate stable components, production scale is easily put
Greatly, it is advantageously implemented dust-removing powder to handle on a large scale, sorting ilmenite concentrate is without drying, direct and fine fraction ilmenite concentrate ball press technique pair
Connect, shorten process procedure, reduce dust generation, save production cost, improve economic benefit.

Drop furnace gas is entered into dust falling system together, therefore the application uses and the side that ilmenite concentrate carries out pelletizing processing is obtained to magnetic separation
Method.
E, the pelletizing made add smelting titanium slag with electric stove after being dried.
Because electric stove dust Powder Particle Size is thin, a large amount of airborne dusts can be caused using conventional processing method, influence production environment and
Operator's health, therefore the sorting technology on sorting technology using humidification, sorting obtain ilmenite concentrate filtering without drying, directly
Connect together to enter with bonding agent and fed to boiler smelting titanium slag is dried after mixed grind pressure ball, pressure ball.
In step A keep slurry in solid content 20%~35%., can in aforementioned range by solid content control in slurry
So as to keep the enough mobility of slurry after adding water, have and utilize follow-up magnetic separation processing.
Magnetic field intensity control is in the range of 0.2T~0.8T in step B.Magnetic field intensity control is reached in aforementioned range
To entering stove ilmenite concentrate head grade.
Ilmenite concentrate slurry after magnetic separation is filtered using the method for vacuum filtration in step C.
Ilmenite concentrate slurry after magnetic separation is filtered using the method for press filtration in step C.
In D steps by filtering after ilmenite concentrate carry out just mixed with adding in fine fraction ilmenite concentrate raw material, sequentially add combination
Agent and water, control mix up material moisture 5%~8%.Moisture refers to that water is accounting for the mass percent of material herein.Using foregoing
Method, helps to form pelletizing, and improve the compression strength of pelletizing.
Cause the pelletizing diameter control that is made in D steps in 5mm~15mm, compression strength of green pel let control 700N with
On.Using the pelletizing of aforesaid standards, it can prevent pelletizing from partly disperseing to form dust in subsequent technique.
The action of forced stirring during step A adds water.Slurry foot is kept after action of forced stirring during adding water can make to add water
Enough mobility, have and utilize follow-up magnetic separation processing.Pelletizing is smelted using electric furnace high-temperature tail gas in E steps, Ke Yichong
Divide the high-temperature tail gas using electric furnace, greatly save the energy.In summary, this method technique is simple, and efficiency high, cost is low, can
Large-scale production is realized, popularization answers prospect preferable.
