Description of the drawings
Fig. 1 is the process flow chart of the method for the present invention.
Specific embodiment
In order to be fully understood by the purpose of the present invention, feature and effect, by following specific embodiments, the present invention is made detailed
It describes in detail bright.For the process of the present invention in addition to the description below, remaining uses the conventional method or device of this field.
Barium slag is the residual solid in barium salt production, belongs to the waste residue of industrial discharge, chemical composition mainly have silica,
The barium compounds salt such as iron oxide, aluminium oxide, calcium oxide, potassium oxide, barium sulfate, barium carbonate.Due to containing free acid, so having
Very strong corrosivity.To soil vegetative cover, water body has very big pollution.Not even a blade of grass grows for storing place.Underground water pollution is difficult to administer.
This industrial residue can not be administered for a long time, become a great problem of barium salt industry.As long as in fact, the iron in barium slag is reduced to
Within 0.4%, this waste residue can produce glass ceramics raw material or production barium glass i.e. using a kind of resource is become.If iron
It is just adapted to and various glass and ceramic products less than 0.1%.Glass industry absorption of market is very big, except the barium silico-calcium after iron is done
Glassware bubble it is few, transparency is high, bright in colour, and has the function of that simple glass is not had, and X-ray-preventing is anti-
The function of ultraviolet light, is safety check, medical examination, nuclear industry, electronics industry, essential resource.Inventor is according to barium slag
Main component with reference to the demand in market, does not generate new waste residue and pollution as standard, it is proposed that solve with production process, terminal
The economically viable technical solution of this pollution sources.
The method of the present invention is described in detail with reference to Fig. 1.
The first step grinds barium slag.Barium slag is ground to 100-400 mesh (British Standard), it is contemplated that the needs of technique and
Cost, preferably 200-300 mesh.It is classified after grinding barium slag, meets the fine slag of above-mentioned granularity requirements by the way that thick slag return is regrinded
Until meeting above-mentioned granularity requirements.Barium slag after grinding is made into barium slag ore pulp, in the incipient stage of production, can be matched somebody with somebody with water
Barium slag ore pulp processed in process of production, can prepare barium slag ore pulp with the water lotion in subsequent step, useless so as to reduce
Water discharges and saves cost, wherein, the solid-liquid mass ratio 1 in ore pulp:1-1:2.5, preferably 1:1-1:1.25.
Second step carries out pipeline sulfuric acid leaching to barium slag ore pulp.By in barium slag ore pulp flow in pipes leaching equipment, and
Implantation quality concentration is the sulfuric acid of 90%-105%, and in leaching process, pressure limit is 16-0.5kg/cm2, preferably 10-8kg/
cm2, i.e. initial pressure 16kg/cm2, terminal pressure 0.5kg/cm2, it is preferable that initial pressure 10kg/cm2, terminal pressure 8kg/
cm2.Reaction pressure is controlled by ore slurry pump and sulfuric acid pump.Make reaction liquid by controlling the ratio of barium slag ore pulp and sulfuric acid
PH value control in 1-4.5, be preferably controlled in 2-3.Reaction time is 5-60 minutes, preferably 10-20 minutes, more preferable 10 points
Clock.
External energy heating is not required in entire leaching system, and the heat of dilution of sulfuric acid and the reaction generation heat of material can meet work
Skill requirement, so that production cost is very low, production efficiency is high.In addition, employing advanced high-efficiency pipeline extract technology makes
Unit ton cost is very low, high degree of automation, yield is big, can be unattended, reduces evaporating, emitting, dripping or leaking of liquid or gas trouble point, operation ring
Border is good.
Sulfuric acid leaching can be converted into soluble barium insoluble barium sulfate, and the iron oxide in barium slag is converted with sulfuric acid reaction
For ferric sulfate, partial oxidation aluminium generates aluminum sulfate with sulfuric acid reaction, and silicon does not generate not capacitive with sulfuric acid reaction, calcium and sulfuric acid reaction
Calcium sulfate so as to obtain aluminum sulfate, ferrous solution, realizes that iron aluminium and barium silico-calcium extract separated purpose.This step mainly relates to
And 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 reaction, the hydrogen sulfide gas of generation is absorbed with soda for pipeline sulfuric acid leaching
Vulcanized sodium is obtained, and to product separation of solid and liquid.
Specifically, pipeline sulfuric acid leaching after reaction, first passes through gas-liquid separation surge tank, isolates stink damp
Body is absorbed to obtain vulcanized sodium with sodium hydroxide；Slurry fluid enters subsider, the filtered purification of overflow clear liquid on subsider top
Afterwards into hydrolytic-polymeric reaction tank with prepare bodied ferric sulfate aluminium water purifying agent { Al (OH) nSO4 } m { Fe2 (OH) nSO4 } m (n≤5,
m≤10)。
Bodied ferric sulfate aluminium water purifying agent is a very ripe high efficiency sewage treating agent.Solid barium slag per ton, which can produce, to be met
National Standard of the People's Republic of China《Water purification agent bodied ferric sulfate》(GB14591-2006) bodied ferric sulfate aluminium water purifying agent 0.5-
0.6 ton.
In this step, gas and liquid are obtained for effective utilization caused by the reaction of pipeline sulfuric acid leaching, from
And realize the zero-emission of gas, liquid and solid.
4th step settles the filtered washing of solid of trench bottom with drying so as to obtain the high barium silico-calcium glass raw material of solid,
The mass content of iron therein is no more than 0.1%, and water lotion returns to the first step for preparing barium slag ore pulp, so as to realize water
It recycles.
5th step by high barium silico-calcium glass raw material in glass frit stove, melts, preferred molten temperature in oxidizing atmosphere
For 800-1650 DEG C, more preferable 800-1200 DEG C；Water extraction is carried out afterwards so as to obtain barium base glass frit.The barium base glass frit
Available for various high-grade glass ceramic glazes.
The method of the present invention relates generally to following equipment：
Pipeline leaching equipment：With the equipment for the purpose that anti-corrosion heat resisting and pressure resisting pipeline surrogate response tank is completed to leach.Using
It is discontinuous operation that retort, which leach, and treating capacity is small, more with worker, and trouble point is more, and yield is few, and efficiency is far below pipeline
Leaching equipment.
Gas-liquid separation surge tank：Pipelineization leach after the completion of mixing mud enter gas-liquid separation surge tank complete gas with
The separated equipment of liquid.
Subsider：Liquid after completion gas-liquid separation consolidates mixing mud and enters liquid and solid natural separation equipment, and top is
Clear liquid bottom is that the high solid of concentration enters filter plant.The effect of subsider is to reduce the workload of filter plant, and can be obtained
To clear fluid product.
Hydrolytic polymerization tank：The extracted liquid for completing filtered purification is hydrolyzed the equipment of polymerization, equipment in itself band stirring,
Temperature, anti-corrosion, compression resistance can be controlled.
Glass frit stove：It is formed by refractory material laying.
Every equipment that disclosure satisfy that above-mentioned function is used equally in the present invention.
