Description
Technical field:
The present invention relates to a kind of flyash separation and Extraction equipment, especially be applicable to the thermoelectricity, thermoelectricity, the large-scale boiler furnace enterprise that uses that produce electric energy with coal-fired form, can directly connect the electric fields at different levels that gather dust and use, also can be used for the dried shape flyash high added value mineral separation and Extraction equipment of flyash storehouse or peripheral processing base.
Background technology
Solid waste, especially flyash, the annual output amount of dumping of China surpasses hundred million tons, has become public hazards.Although in the cement manufacturing, build the road, build in dam, the materials for wall and can partly utilize, belong to the low value utilization.The present invention is intended to high added value thing phase---the separation and Extraction of microballon, magnetic bead and carbon residue in the flyash, makes it become the Multifucntional material that can be widely used in metallurgy, chemical industry, oil, rubber, building materials, thermal technology, light industry, military affairs, navigation space flight, electronic communication, agricultural, environmental protection, field such as civilian.As former pearl can be used for that thermal technology's industry production sintering, non-sintering are fire-resistant, fire resistant heat preserving, Thermal insulation articles; Metallurgy industry replaces expensive metal preparation and is used to make steel that ironmaking processes grain refinement resistance oxygen covers and direct original production sial series alloy etc. also; Purify microballon at building material industry, be used to produce fire prevention, waterproof, stealth, sound insulation coating, wear-resisting and antifouling paint, heavy caliber fiberglass sandpipe, high-strength wearable concrete etc.; The activation microballon is wear-resisting, anti-corrosion, the high-strength inserts of vast scale of rubber, plastics, paper industry, is again good catalyst carrier of chemical industry and resin inserts and the slip casting of petroleum industry oil gas field, well cementing material; Strengthen the clear stain remover of palliative, offshore oil, desalinization absorbent filter medium, rocket launching base temperature-resistant material that microballon both can be used as aerospace craft protective layer material, submarine and bathyscaphe, plate armour " dual firmness steel plate " is high temperature resistant anti-ly penetrates thermal synthesis layer, can be used for sintered carbide tools, high-performance grinding materials and grinding tool and anti-fusion container against corrosion etc. again; After the rich iron microballon magnetization is good electromagnetic shielding material, can be used for military affairs, civilian radioresistance, anti-interference engineering, and it is good adsorption scavenging material and abrasive material that carbon residue is cellular.
Flyash is coal-fired thermoelectricity, thermoelectricity, the large-scale large solid waste with generation in the boiler furnace production of enterprise.Coal in combustion process, non-carbonizable substance [dewater about 550 ℃ as coal measures clay mineral (kaolinite, illite etc.), become amorphous phase mutually from monoclinic crystal, from 1000～1300 ℃ of fusion and decomposition gradually, produce chemical change, wherein kaolinite changes as follows:
Fusing back is shrunk to drop naturally under its surface tension effects, the pearl body that after swiftly flowing gas cooled, forms naturally, and the uncombusted coal becomes carbon granules, and complete fusion does not become unsetting things such as dust, and iron content is high becomes rich iron shot.Through flyash being carried out detailed chemistry, mineralogical composition analysis, finding wherein to contain a large amount of high added value mineral compositions; As floating pearl, microballon, poor iron microballon, rich iron microballon, carbon residue etc., its chemical analysis and mineral composition see Table 1, with its separation and Extraction, are a kind of good natural resources.
