Accompanying drawing explanation
Fig. 1 is the process chart of the inventive method.
Detailed description of the invention
In order to be fully understood by the purpose of the present invention, feature and effect, by following detailed description of the invention, to this
Invention elaborates.The process of the present invention is in addition to the description below, and remaining all uses the routine of this area
Method or apparatus.
Barium slag is the residual solid during barium salt produces, and belongs to the waste residue of industrial discharge, and its chemical composition mainly has two
The barium compound salts such as silicon oxide, ferrum oxide, aluminium oxide, calcium oxide, potassium oxide, barium sulfate, brium carbonate.
Due to containing free acid, so there being the strongest corrosivity.To soil vegetative cover, water body has the biggest pollution.Deposit
Not even a blade of grass grows to put ground.It is difficult to administer to underground water pollution.This industrial residue cannot be administered for a long time, becomes barium
The a great problem of salt industry.As long as it is true that within the ferrum in barium slag is reduced to 0.4%, this waste residue
I.e. may utilize and become a kind of resource, glass ceramics raw material can be produced or produce barium glass.If ferrum is less than 0.1%
Just adapt to and various glass and ceramic products.Glass industry absorption of market is the biggest, except the barium silico-calcium after ferrum
The glass bubble done is few, and transparency is high, bright in colour, and has the merit that simple glass does not has
Can, X-ray-preventing, the function of anti-ultraviolet, is safety check, medical examination, nuclear industry, electron trade,
Requisite resource.Inventor is according to the main component of barium slag, in conjunction with the demand in market, with production process,
Terminal does not produce new waste residue and pollutes for standard, it is proposed that solve the economically viable technology of this polluter
Scheme.
Below in conjunction with Fig. 1, the method for the present invention is described in detail.
The first step, grinds barium slag.Barium slag is ground to 100-400 mesh (British Standard), it is contemplated that technique
Needs and cost, preferably 200-300 mesh.Carry out classification after grinding barium slag, meet above-mentioned granularity requirements
Fine slag pass through, thick slag return regrind until meeting above-mentioned granularity requirements.Barium slag after grinding is made into barium slag
Ore pulp, in the incipient stage produced, can prepare barium slag ore pulp with water, in process of production, and can be with
Water lotion in subsequent step prepares barium slag ore pulp, such that it is able to reduce discharge of wastewater cost-effective, its
In, solid-liquid mass ratio 1:1-1:2.5 in ore pulp, preferably 1:1-1:1.25.
Second step, carries out pipeline sulfuric acid leaching to barium slag ore pulp.Barium slag ore pulp flow in pipesization is leached and sets
In Bei, and implantation quality concentration is the sulphuric acid of 90%-105%, and in leaching process, pressure limit is 16-0.5
kg/cm2, preferably 10-8kg/cm2, i.e. initial pressure 16kg/cm2, terminal pressure 0.5kg/cm2, preferably
Ground, initial pressure 10kg/cm2, terminal pressure 8kg/cm2.Reaction is controlled by ore slurry pump and sulfuric acid pump
Pressure.The pH value of reaction liquid is made to control at 1-4.5 by controlling the ratio of barium slag ore pulp and sulphuric acid,
It is preferably controlled in 2-3.Response time is 5-60 minute, preferably 10-20 minute, more preferably 10 minutes.
Whole leaching system need not external energy heating, and the reaction of the heat of dilution of sulphuric acid and material generates heat can
Meeting technological requirement, so that production cost is the lowest, production efficiency is high.It addition, have employed the height of advanced person
Effect pipeline extract technology makes unit ton cost the lowest, and automaticity is high, and yield is big, can be unmanned
On duty, reduce evaporating, emitting, dripping or leaking of liquid or gas trouble point, working environment is good.
Sulfuric acid leaching can be converted into soluble barium sulfate solubility barium, and the ferrum oxide in barium slag is anti-with sulphuric acid
Should be converted into iron sulfate, partial oxidation aluminum generates aluminum sulfate with sulfuric acid reaction, silicon not with sulfuric acid reaction, calcium with
Sulfuric acid reaction generates not capacitive calcium sulfate, such that it is able to obtain aluminum sulfate, ferrous solution, it is achieved ferrum aluminum and barium silicon
Calcium extracts the purpose separated.This step relates generally to following chemical reaction:
BaS+H2SO4→BaSO4↓+H2S↑
Fe2O3+3H2SO4→Fe2(SO4)3+3H2O
AI2O3+3H2SO4→AI2(SO4)3+3H2O
CaO+H2SO4→Ca SO4↓+H2O
3rd step, gas-liquid separation.After the reaction of pipeline sulfuric acid leaching terminates, the hydrogen sulfide gas produced is used
Soda absorbs and obtains sodium sulfide, and to product solid-liquid separation.
Specifically, after the reaction of pipeline sulfuric acid leaching terminates, first pass through gas-liquid separation surge tank, isolate sulfur
Change hydrogen, absorb with sodium hydroxide and obtain sodium sulfide；Slurry fluid enters subsider, subsider top
Overflow clear liquid enters hydrolytic-polymeric reaction tank to prepare bodied ferric sulfate aluminium water purifying agent after filtration, purification
{ Al (OH) nSO4}m{Fe2 (OH) nSO4}m (n≤5, m≤10).
Bodied ferric sulfate aluminium water purifying agent is a high efficiency sewage treating agent the most ripe.Solid barium slag per ton can be given birth to
Product meets National Standard of the People's Republic of China " water purification agent bodied ferric sulfate " (GB14591-2006) and gathers
Close ferric aluminium sulfate water purification agent 0.5-0.6 ton.
In this step, the produced gas of pipeline sulfuric acid leaching reaction and liquid are obtained for effective profit
With, it is achieved thereby that the zero-emission of gas, liquid and solid.
4th step, the solid bottom subsider is washed through drainage and is dried thus obtains solid height barium silico-calcium glass
Raw material, the mass content of ferrum therein is less than 0.1%, and water lotion returns the first step and is used for preparing barium slag ore deposit
Slurry, such that it is able to realize water circulation use.
5th step, by high barium silico-calcium frit in glass frit stove, melted, preferably in oxidizing atmosphere
Melt temperature is 800-1650 DEG C, more preferably 800-1200 DEG C；Carry out water extraction afterwards thus obtain bario glass
Glass frit.This bario glass frit can be used for various high-grade glass ceramic glaze.
The method of the present invention relates generally to following equipment:
Pipeline leaching equipment: complete the setting of purpose leached with anticorrosion heat resisting and pressure resisting pipeline surrogate response tank
Standby.Using retort to carry out leaching is discontinuous operation, and treating capacity is little, many with workman, and trouble point is many, yield
Few, its efficiency is far below pipeline leaching equipment.
Gas-liquid separation surge tank: the mixing mud entrance gas-liquid separation surge tank after pipelineization has leached completes
The equipment that gas separates with liquid.
Subsider: complete the liquid-solid mixing mud after gas-liquid separation and enter liquid and solid natural separation equipment,
Top is to be that the solid that concentration is high enters filter plant bottom clear liquid.The effect of subsider is to reduce filter plant
Workload, clear fluid product can be obtained again.
Hydrolytic polymerization tank: complete through the extracted liquid of filtration, purification be hydrolyzed polymerization equipment, equipment itself
Band stirs, can control temperature, anticorrosion, compression resistance.
Glass frit stove: formed by refractory material laying.
Every equipment that disclosure satisfy that above-mentioned functions is used equally in the present invention.
Bario glass frit prepared by the method for the present invention easily stores, and easily packs, and cost of transportation is low, user
Use and in producing, there is no the harmful gas erosion to resistance to material, furnace service life long production low cost, good product quality,
Constant product quality.
Further illustrate the present invention below by the mode of embodiment, but the most therefore limit the present invention to institute
Among the scope of embodiments stated.The experimental technique of unreceipted actual conditions in the following example, according to routine side
