Abstract
The invention is an anthracitic coking additive, as preparing coal for coking, mixing in anthracite by 10-50% and mixing in it a little to be able to refine high quality coke. And it comprises shrinking agent, coking agent and equalizer, where the shrinking agent is composed of strong acid weak alkali salts and weak acids, PH 2-7; the coking agent comprises water soluble high molecular compounds, animal glue, plant glue, and residue; and the equalizer is composed of surface active agent. By the integrated action of the three matters in it, high quality coke can be refined from coking coal mixed with anthracite.
Description
Technical field
The invention belongs to the coking technology field, is a kind of anthracitic coking additive.
Background technology
At present the coke-oven plant mainly adopts coking coal (comprise coking coal, help coking coal, 1/3 coking coal, rich coal, bottle coal) coking, but coking coal only accounts for about 10% of world's coal reserves, though China is higher, also only account for about 27%, and meet field conditions still less, according to present recovery rate, just may there be coal coking after 50 years, coke-free ironmaking.And hard coal accounts for about 70% of world's coal reserves, and contain ash, sulfur-bearing is low, so to adopt with addition of anthracite cocking be that to alleviate coking coal under-supply in the coke-oven plant, the effective way that reduces cost.But still can only and make firm by ramming at present and add a spot of hard coal in the burnt mixed coal at formed coke.
Summary of the invention
The objective of the invention is: a kind of anthracitic coking additive is provided, it is joined joined to go in 10～50% anthracitic coking mixing coals stove and can produce and discharge of the coke.
Additive of the present invention is composed as follows: anthracitic coking additive of the present invention is made up of shrinking agent, coking agent, leveler, wherein shrinking agent is made up of the strong acid weak base salt and the weak acid of 2＜PH＜7, and strong acid weak base salt comprises the amine salt and the metal cation salt of 2＜PH＜7 such as halogenide, nitrate, vitriol, phosphoric acid salt, carbonate, borate, manganate, chromic salt, molybdate, tungstate, aluminate, zincate, silicate, halogen silicate, halogen aluminate, halogen borate.Weak acid is made up of the organic acid of 2＜PH＜7.It can improve the coke shrinkage, increases degree of compactness.
The coking agent is made up of water-soluble organic macromolecule compound, gelatin, vegetable jelly, water-insoluble organic high molecular compound, residual oil etc.As Mierocrystalline cellulose, polyvinyl alcohol, caprolactam, ox glue, gelatin, gum arabic, residual oil, etc.It can carry the coke adhesive property.
Leveler is made up of tensio-active agent, and tensio-active agent comprises anion surfactant, cats product, nonionogenic tenside, amphoterics, polymeric surface active agent, special surface active agent.It can impel coking coal to mix evenly with hard coal.
The compound method of the anthracitic coking additive of this amount is as follows: 1. the additive all components is all water-soluble, then each component is made into the aqueous solution in proportion; 2. all components all is dissolved in organic solvent in the additive, then each component is made into organic solvent in proportion; 3. all or part of energy of the component in additive emulsification, and other component can be water-soluble, then each component is made into emulsion in proportion; 4. there is the part component both water insoluble in the additive, can not emulsification, then each component is made into outstanding finish or each component is made into pulvis in proportion in proportion; Though 5. the component in the additive can not be water-soluble, its complex compound is water-soluble, and then each component is made into complex solution in proportion.
The blending means of anthracitic coking additive of the present invention and coal: 1. earlier additive is mixed with hard coal again and mix with coking coal; 2. earlier with hard coal with will mix coal again after coking coal mixes and mix with additive.The add-on of additive is for mixing 0.01～10% of coal weight.
Embodiment:
It is that zinc phosphate 4%, zinc chloride 6%, hexanolactam 3%, temperature-80 are a kind of prescription that 3% the aqueous solution is anthracitic coking additive of the present invention that zinc phosphate, zinc chloride, hexanolactam, temperature-80 are made into content.Then this additive is mixed with hard coal, mix the coal blending work of promptly finishing again with coking coal, wherein the hard coal add-on is 25%, and the add-on of aqueous solution additive is for mixing 5% of coal weight.
