Abstract
The invention discloses a method for producing cold bound pellet agglomerate through solid waste and hazardous waste. The solid waste and hazardous waste such as converter sludge, power sludge, different types of fly ash produced in ferrous metallurgy production, and a large amount of sulfuric-acid residues, chromic slag, electroplating sludge, chemical industry sludge, petroleum sludge (catalysts) and other chemical industry solid waste and hazardous waste which are produced in the chemical industry production are subjected to technology processing such as crushing, levigating, burdening, mixing, disc balling and sintering to produce the agglomerate which can be used for a blast furnace, so that the ultimate purposes of harmlessness and reclamation of the solid waste and hazardous waste are achieve, and the good socioeconomic benefits and eco-environment benefits are achieved.
Description
Technical field
The present invention relates to solid waste, the useless field of comprehensive utilization of danger, relate more specifically to a kind of method utilizing solid waste danger useless production cold-consolidated ball sintering deposit.
Background technology
Turning during Ferrous Metallurgy produces converter mud, power mud, the solid waste such as all kinds of dedusting ash and the danger produced at present useless, the useless main processing ways of the chemical industry solid waste such as a large amount of sulfate slags of producing in Chemical Manufacture, chromium slag, electroplating sludge, chemical engineering sludge, petroleum sludge (catalyst), danger is:
Landfill stabilization: floor space is big, it is impossible to realize innoxious, minimizing, the final purpose of resource, the gradually seepage of passage in time and produce secondary pollution.
With the cooperative disposal such as cement kiln: can only add on a small quantity, it is impossible to solve a large amount of this type of Industrial Solid Waste produced and danger refuse.Can not be fully achieved innoxious, it is impossible to thoroughly detoxify.Special flue gas processing device is not had to cause secondary pollution.
The collaborative metallurgical equipment of burning mode processes: only use burning mode, many heavy metals cannot process, serious secondary pollution will be produced, Cr VI such as can only be converted into the trivalent chromium of instability, oxidizing atmosphere or have humidity air in can be reoxidized for Cr VI, if crome metal need to be converted into, needing great amount of investment to build up smelting system and dispose, its investment and cost all can be the highest.
Therefore, can solve the problem that the indeterminable problem of said method in the urgent need to one, and realize the comprehensive utilization that solid waste, danger are given up, thus reach solid waste, the useless innoxious and final purpose of resource of danger.
Summary of the invention
The present invention discloses and a kind of utilizes the useless method producing cold-consolidated ball sintering deposit of metallurgy, chemical industry solid waste, danger, will Ferrous Metallurgy produce in the converter mud, power mud, the solid waste such as all kinds of dedusting ash and the danger that produce useless, a large amount of sulfate slags of producing in Chemical Manufacture, chromium slag, electroplating sludge, chemical engineering sludge, the chemical industry solid waste such as petroleum sludge (catalyst), danger are useless by pulverizing the PROCESS FOR TREATMENT such as levigate, dispensing, mixing, disk pelletizing, sintering, produce into and be available for the sintering deposit that blast furnace uses, thus reach solid waste, the useless innoxious and final purpose of resource of endangering.
Process route is as follows:
Raw material processing system (by all raw materials and solid, danger is useless is finely ground to about 200 mesh sieve) feed proportioning system (reasonable dispensing, both reach purpose solid, that danger is useless of dissolving, ensure that again the every physicochemical property of blast furnace ironmaking requires) mixing disk pelletizing (uniformly causing the pelletizing of 5～15mm by sintering requirement) continuous pallettype sintering machine sintering sintering deposit (final products).
Gu, heavy metal such as the chromium, nickel of hazardous waste pollution thing predominantly severe toxicity and Organic substance such as coal-tar residue, phenols.Being postponed by the place of above rationally dispensing and process route, under high temperature and reducing atmosphere, heavy metal is partly or entirely reduced and is stayed in sintering deposit, and Organic substance is burnt by pyrolytic, no longer produces harm.Sintering deposit is the base stock of metallurgical industry blast furnace, finally thoroughly eliminates weight, danger Substances Pollution in blast furnace process, reaches innoxious and resource purpose.
According to solid waste of the present invention, the useless proportion scale of danger to be prone to pelletizing and to meet sintering deposit product quality and require as principle, be not specially limited at this, i.e. solid waste, danger useless both can independent pelletizing, again can mixed pelletizing, also can be with iron mine raw ore mixture pelletizing.The temperature range that continuous pallettype sintering machine uses is 1000～1300 DEG C, and preferred range is 1100 ± 50 DEG C.Belt sintering can be produced and be available for the sintering deposit that industry blast furnace uses, and has both guaranteed removing toxic substances, realizes again solid waste, useless innoxious and resource of endangering, has good social economy and ecological environment benefit.
