Description

A kind of utilization fusion method processes discarded lead bearing glass and the method for preparing devitrified glass
Technical field
The present invention relates to the preparation method of the process of discarded lead bearing glass and devitrified glass, and in particular to one kind is using melting The discarded lead bearing glass of method process and the method for preparing devitrified glass.
Background technology
Because lead bearing glass can effectively absorb X-ray, it is widely used in production cathode ray tube（Cathode Ray Tube, abbreviation CRT）.With the fast development of display technology so that increasing cathode ray tube display is eliminated, Therefore substantial amounts of discarded CRT is generated.The annual CRT learies of China are huge, while there is useless CRT in a large number to pass through back door China is transported to from developed country, the process of discarded CRT has become one of major issue during China's electron wastes are processed. The leaded up to 20-25% of cone glass in CRT, if discarded CRT is arbitrarily placed, will produce serious danger to water source, soil and air Evil, and jeopardize the healthy of the mankind.Due to the special structure of cone glass, it is difficult with conventional mode and reclaim in lead, cause The present situation of discarded lead bearing glass difficult treatment.
Meanwhile, the country produces every year the industrial residues such as a large amount of flyash, magnesite slag, except small part waste residue is made into water Mud, as roadbed outside, most of waste residue air storage not only occupies soil, also to environment.Work is directed to both at home and abroad The process of industry waste residue is disposed and has carried out numerous studies, wherein make devitrified glass using waste residue increasingly being closed by people Note.
Devitrified glass is a kind of by melting cold quenching and then controlling polycrystalline material obtained in crystallize, with many excellent property Can, its performance indications is often better than similar glass and ceramics.The devitrified glass prepared using metallurgical slag, flyash or cullet System mainly has CaO-Al2O3-SiO2(CAS)、CaO-Al2O3- Fe2O3 - SiO2 (CAFS)、MgO-Al2O3-SiO2(MAS) System, the devitrified glass principal crystalline phase without system is different, and the material property for obtaining is also different.Compare CAS microcrystalline glass in series, MAS Microcrystalline glass in series can separate out various crystalline phases of superior performance, heavier with the good characteristic such as high mechanical strength, thermal-shock resistance be good Want, this kind of devitrified glass can be entirely free of alkali metal ion, so as to obtain excellent electrical property.In recent years, with regard to profit The research for preparing devitrified glass with flyash, metallurgical slag or discarded lead bearing glass is reported in a large number, but these methods are most It is the heavy metal lead in lead bearing glass to be fixed in the product, so as to reduce pollution using the method for solidification.So not only waste Precious resources, and lead still causes in product and potentially threatens and affect properties of product, limits the application of product.
The content of the invention
For the problem that prior art is present, the present invention provides one kind and processes discarded lead bearing glass using fusion method and prepare The method of devitrified glass.The technical scheme is that：
Lead bearing glass and the method for preparing devitrified glass are discarded using fusion method process, is comprised the following steps：
Industrial residue and discarded lead bearing glass are crushed to into respectively 0.074-0.5mm；
By industrial residue, discarded lead bearing glass, composition adjustment agent, nucleating agent and coke mix homogeneously, and control the change of mixture Learn composition is according to mass percent：SiO235-45%, Al2O312-17%, MgO 14-19%, R2O 3-7%, CaO 3-6%, Fe2O32-6%, TiO2Or ZrO24-10%, PbO 8-12%, wherein R2O represents K2O and Na2O；
By mixed material in 1400-1600oMelting 2-3 h under C, isolate and upper strata vitreous humour are obtained after lower floor's lead bullion；
Upper strata vitreous humour is annealed successively, coring, crystallization, devitrified glass is obtained after cooling.
In said method, the industrial residue is the one kind in flyash, magnesite slag or two kinds.
In said method, the discarded lead bearing glass is the cone glass of discarded cathode ray tube.
In said method, the composition adjustment agent is that dolomite or both dolomite and Anhydrite mix.
In said method, the nucleating agent is TiO2、ZrO2In one kind.
It is described that industrial residue, discarded lead bearing glass, composition adjustment agent, nucleating agent and coke mixing is equal in said method It is even, i.e., with industrial residue, the gross mass of lead bearing glass, composition adjustment agent, nucleating agent is discarded as 100%, wherein industrial residue is added Measure as 35-50%, it is 30-40% to discard lead bearing glass addition, and dolomite addition is 5-14%, and Anhydrite addition is 0-10%, Nucleating agent addition is 5-10%；Coke addition is 1.1-1.5 times of discarded lead bearing glass quality.
In said method, the purity of lower floor's lead bullion is more than 98%.
In said method, it is described upper strata vitreous humour is annealed successively, coring, crystallization, wherein the annealing conditions are：Annealing Temperature 550-650 DEG C, temperature retention time 2-4h；The coring condition is：5-10 DEG C of heating rate/min, nucleation temperature 700- 800oC, temperature retention time 1-3h；The crystallization condition is：2-5 DEG C of heating rate/min, crystallization temperature 850-1000oC, during insulation Between 2-3h.
In said method, below 1%, lead recovery is more than 93% for the lead tolerance of the devitrified glass.
The present invention adopt industrial residue and the synergistic principle of discarded lead bearing glass for：Containing alkaline oxygenated in industrial residue Thing（Such as MgO, CaO）And amphoteric oxide（Such as Al2O3, basic anhydride are shown as in acid condition）, using these oxidations Thing replaces the alkaline assistant required for discarded lead bearing glass carbon thermal reduction, reduces slag viscosity, enables the lead of lead bearing glass suitable Profit reduction simultaneously settles aggregation；Correspondingly, the SiO in lead bearing glass2When can replace quartz sand as devitrified glass is prepared with waste residue Additive, while the Na in glass2O and K2O plays a part of to flux to waste residue.The present invention takes full advantage of heat energy, by glass Melting is reduced with lead and synchronously carried out, and greatly reduces energy consumption.
Compared with existing industrial residue or lead bearing glass prepare devitrified glass technique, beneficial effects of the present invention are as follows：
（1）Process is simple, low cost, it is only necessary to which once melting can complete the preparation of parent glass liquid and the reduction of lead, can play Energy-saving and emission-reduction and the effect of reducing energy consumption.
（2）Lead in lead bearing glass is reduced to metallic lead, has both been inherently eliminated the lead contamination of lead bearing glass, makes again Lead resource is utilized, and produces economic benefit, additionally, reducing the lead tolerance in devitrified glass product, improves properties of product.
（3）Industrial residue and discarded lead bearing glass are converted into into high value added product, environmental pollution are eliminated, with good Environmental benefit, economic benefit and social benefit.
