Description
Technical field
The utility model relates to the change system of a kind of vanadium extraction bone coal desulphurizing roasting and cogeneration.
Background technology
China is containing carbon shale (being commonly called as bone coal) aboundresources, but gangue and mineral composition differ greatly contained by different zones bone coal, bone coal thermal value generally between 450 × 4.18KJ/kg ~ 1600 × 4.18KJ/kg, bone coal sulfur-bearing generally between 0.8 ~ 4.5%, as V in bone coal
2o
5content>=0.7% time, generally exploit as navajoite.
The roasting of vanadium extraction bone coal is the critical process of extracting vanadium from stone coal, affects greatly on vanadium transformation efficiency and vanadium extraction efficiency, and the roasting method of current maturation application has stone coal sodium roasting and bone coal oxidizing roasting two kinds.
Stone coal sodium roasting method be bone coal is added fat coal and add more than 1% Industrial Salt, through broken, grinding, make pellet, then carry out the method for roasting.Because the method adopts earth kiln or boiler-turbine CCS device, in the sulphur chlorine dual function of stone sulfur content in coal and added Industrial Salt, environmental protection treatment is very difficult, the trees near stoving oven in several kilometers and crops sheet is caused to be withered, used heat is also all wasted, both contaminate environment, consumes mass energy again.
Bone coal oxidizing roasting method, uses the stoving oven roasting of building materials and chemical industry, is generally that first fragmentation adds fat coal roasting decarburization, and then the oxidizing roasting that burns gas, to improve the transformation efficiency of vanadium, and its flue gas SO
2quantity discharged is large, and process more difficult, medium and small sized enterprises are nearly all reluctant that investing tens million of unit builds flue gas desulphurization system, causes actual SO
2a large amount of directly discharge, same serious environment pollution, both consumed mass energy, and the used heat energy consumption of roasting is also all thrown aside.
CN101776391A discloses a kind of fluidizing furnace for vanadium extraction and decarbonization of stone coal, be difficult to for existing fluidizing furnace the situation that calcination process calorific value is less than the Rock coal containing alum of 1000 × 4.18KJ/kg, the method provided is " on the main bed of fluidizing furnace and secondary bed, increase coal gas combustion-supporting mode, gas-fired is utilized to provide heat, realize the boiling furnace combustion of low heat value Rock coal containing alum, ", low heat value bone coal described in it is the Rock coal containing alum that calorific value is less than 1000 × 4.18KJ/kg, and objectively most bone coal calorific value at 600 ~ 1000Kcal/kg scope (1 Kcal=4.1816KJ).
CN202792967U discloses a kind of stone coal vanadium-extracting roasting equipment, " comprising: for the first stoving oven of stone coal decarbonization and the second stoving oven for vanadium conversion; described first stoving oven and the second stoving oven are Fludized boiling stove; ... ", described in it " novel Fludized boiling stove; by burner SA supplementing energy is conducive to controlling the condition that decarburization or vanadium transform." " ... burner SA, for spraying heavy oil in furnace chamber, the fuel such as Sweet natural gas or diesel oil, to provide the institute of roasting in furnace chamber heat requirement ".
Chinese patent CN102534193A discloses a kind of method of Rock coal containing alum being carried out to decarburization and roasting, its equipment adopted is circular fluid bed or fluidizing furnace, step comprises: according to the difference of raw material thermal value and characteristic, raw material is handled as follows: add super sea coal and mix, make its thermal value higher than 750Kcal/kg, the additive adding 0 ~ 20% again mixes, then through fragmentation again abrasive dust make 80 ~ 200 object powders, again powder is made the spherical material of 1 ~ 20 millimeter, afterwards, by spherical material decarburization roasting, slag after spherical material roasting carries out bakes to burn the article again.
Through retrieving domestic and international vanadium extraction bone coal roasting method data, and the bone coal calciner taking a broad survey domestic and roasting method, Problems existing is: lack a kind of method and apparatus that can give full play to the calorific value of bone coal material grain own simply and utilize torrefaction waste gas waste heat, especially lack and a kind ofly give full play to the most large 600 × 4.18KJ/kg ~ 1000 × 4.18KJ/kg (theoretical and test proves compared with the apparatus and method of the calorific value of low heat value bone coal material grain own, give full play to the calorific value of 600Kcal/kg bone coal, in-furnace temperature can reach more than 900 DEG C), and the current technical measures taked are mostly by adding fat coal or coming combustion-supporting with oil gas heat supply, cause the carbon of bone coal granule interior can not produce reduction (bone coal material intragranular portion carbon reduced iron by oxidizing fire in time, vanadium, sulphur etc.), cause the incomplete decarburization of bone coal (inner carbon reduced iron, vanadium, sulphur etc.) and the oxidation conversion obstacle of vanadium, both directly affects the transformation efficiency of vanadium, caused again the Heavy environmental pollution disaster that vanadium extraction bone coal roasting various places are general, wasted a large amount of roasting waste heat energy, therefore, in the urgent need to a kind of vanadium extraction bone coal desulphurizing roasting and the change system utilizing cogeneration.
