Incineration of refuse flyash is the molecule discharged in Refuse Incineration Process, wherein contains the things such as heavy metal, two English Matter, belongs to hazardous waste.China《Hazardous Wastes Management technological policy for treatment》The 9th in (State Environmental Protection Administration, 2001) The regulation to flying dust for the bar:The long-term storage in ground must not produced;Must not simply be disposed and be discharged.Garbage-incineration smoke purifying system The bottom ash of system trapping thing and flue sedimentation constitutes flying dust, flying dust produce ground must carry out necessary stabilisation and cured it After can transport, described stabilisation refer to using the materials such as the heavy metal in medicament and flying dust occur chemical reaction (such as dissolving, Precipitation, chelating etc.), pollutant are transformed into the little material with stable chemical nature of dissolubility, described solidification refers to utilize pelletize Equipment make stabilisation after flying dust molding and there is certain intensity.
The treatment technology of incineration of refuse flyash is a lot, mainly have cement solidification, chemical agent stabilisation, sour solvent to extract, Melting and solidification etc..Wherein, due to having the advantages that stable chemical nature, non-secondary pollution problem, melting and solidification technology is considered It is presently the most advanced flyash treatment method for waste incineration, minimizing, innoxious, resource all have great advantage.Should Technology is under 1300 DEG C~1500 DEG C of hot conditionss, the Organic substance in flying dust is decomposed, gasifies, and inorganic matters are melt into glass Glass matter slag.This technology can realize lime-ash volume reduction to greatest extent, realize heavy metal stabilization and thorough elimination two simultaneously English pollutant, and the flying dust after vitrification can serve as building or paveio(u)r, have effectively achieved the resource profit of waste With.
Because the requirement to high temperature and reducing atmosphere for the melting and solidification technology is higher, technology widely used at present mainly includes Oxygen-enriched coke technology, electric fusion technology and plasma melting technology etc..Oxygen-enriched coke technology is mainly derived from Ferrous Metallurgy technology, This technology relies primarily on the high temperature that coke produces under oxygen enriched environment and is melted flying dust, and the consumption of STRENGTH ON COKE is higher.Electricity Fusion technology adopts electric heater substitute for coke to produce thermal source, but there is a problem of that equipment corrodes, heating element heater changes complexity.Deng Ion fusion technology is broadly divided into torch technology and arc technology, and the former relies primarily on the high-temperature gas of plasma torch generation to material Heated, the latter is heated to material by the high-temperature electric arc that negative and positive interpolar produces.Because plasma melting technology has The advantages of energy efficiency is high, production process cleans, do not use coke, is currently paid attention to by more and more researcheres.
But, also there is obvious defect in existing plasma fusing fly ash processing method and processing device.Existing plasma Adopting the plasma torch technology of metal electrode fusing fly ash processing meanss, furnace interior has multiple layer refractory, insulation material more As furnace lining.Although this device can process the flying dust of consumer waste incineration generation, however it is necessary that substantial amounts of auxiliary gas and water Cold, lead to the thermal efficiency of plasma melting stove to reduce, power consumption increases, and easily causes cooling water to leak into plasma melting In stove, bring safety problem.Because in flying dust, chlorinity is higher, therefore stove is contained within substantial amounts of hydrogen chloride gas, leads to metal Electrode is easily corroded.In addition, in flue gas of refuse burning processing procedure, using dry method/semidry method deacidification technique, making in rubbish Chlorine gather in flying dust, but be released again in plasma melting stove and change into hydrogen chloride, if adopt again dry method/ Semidry method deacidification technique collects chlorine, not only causes operating cost to increase, and produces substantial amounts of secondary flying ash, increased gas and shows Heat loss, reduces the thermal efficiency, increases processing cost.Therefore, for fusing fly ash technology, existing plasma treatment work Skill, does not fundamentally solve the handling problems of flying dust, and produces a large amount of secondary pollutions, such as hydrogen chloride etc..
In order to solve above-mentioned technical problem, the present invention provides a kind of thermal efficiency height, compact conformation, can fundamentally solve Incineration of refuse flyash minimizing, innoxious, resource plasma melting processing system.This plasma melting processing system adopts Based on the fusing fly ash technology of plasma arc technology, realize maximum incineration of refuse flyash minimizing, innoxious, resource Change, coordinate perfect technique, make the discharge standard that standard limit of smog release is higher than European Union 2010;Plasma gasification melting operation temperature Degree is usually 1500 DEG C about it is sufficient to decompose all of Organic substance completely, and can will form the organic molecule of two English Thoroughly break up, thus the generation of two English has been prevented from source;Under the hot environment of plasma melting stove, institute's organic/inorganic substance Fully melt, harmful heavy metal is evenly distributed in hot slag, when thermosol slag discharges plasma melting furnace rear, be quickly cooled to glass Glass form, all heavy metals are cured in the middle of vitreous body it is impossible to ooze out, thus reaching the effect that lime-ash goes to poison;Using salt Harmful secondary pollution is fundamentally changed into product by acid recovery technology.
As shown in figure 1, incineration of refuse flyash plasma melting processing system proposed by the present invention includes:Feed arrangement, etc. Ion melting furnace, dual firing chamber, chilling tower, activated carbon injection apparatus, sack cleaner, salt acid generator, wet scrubbing tower, steam Heater, air-introduced machine etc..
The flying dust being produced Refuse Incineration Process by feed arrangement and the additive including such as sand are by certain After ratio mix homogeneously, send into plasma melting stove.Flying dust is stored in flying dust storehouse, and additive is stored in additive bin, by unloading Flying dust in flying dust storehouse is delivered to flying dust metering device and is carried out flying dust and weighs by material valve, will be added by discharge valve and conveying worm Additive in agent storehouse is delivered to additive metering device and is added agent and weighs, and flying dust metering device and additive metering device are only Erect and put.Flying dust after mix homogeneously and additive are sent into from the top of plasma melting stove via batcher etc. by a certain percentage Ion melting furnace, meanwhile, the working gas for producing reducing atmosphere also sends into plasma by the top of plasma melting stove Melting furnace, described working gas adopts nitrogen.
Plasma result from the continuous consumption positioned at stove top graphite electrode and be located at furnace bottom electrode it Between, usual nitrogen is as plasma process gas.It is micro-negative pressure operation in plasma melting stove, in stove, refractory material is water cooled But, to reduce the erosion to refractory material in stove of melten glass liquid and plasma to greatest extent.Inputted by feed arrangement The high-temperature electric arc of produced by plasma 5000 DEG C~8000 DEG C of mixing material melts rapidly, and the melten glass liquid of formation has Electric conductivity, the temperature of melten glass liquid in stove is maintained 1450 DEG C~1600 DEG C by the resistance heat of generation and plasma jointly.
The glass dregs outlet continuous overflow from plasma melting stove bottom for the melten glass liquid is come out of the stove, cooled acquisition glass Slag.The metal reclaiming is discharged out of the furnace by the regulus outlet of plasma melting stove bottom, cooled acquisition metal alloy.Flying dust Two interior English are destroyed by the ultraviolet rays of high-temperature plasma and its generation and melten glass liquid almost all.Plasma melting The flow melting the flue gas of stove generation is very low, and flying dust per ton about produces 200Nm3Flue gas, from the top of plasma furnace discharge Flue gas temperature at 1200 DEG C about.
The flue gas discharged from the top of plasma melting stove is admitted to the bottom of dual firing chamber, under 1100 DEG C about of high temperature By exhaustive oxidations such as CO, the CH4 in flue gas.For avoiding the generation again of two English, the flue gas discharged from the top of dual firing chamber will It is cooled to rapidly 180 DEG C~200 DEG C in chilling tower.Subsequently, by activated carbon injection apparatus, activated carbon is injected and connect chilling Tower and the flue of sack cleaner, to absorb micro two English that may be formed again in flue gas.All of secondary flying ash (flying dust not being melted that includes being carried by flue gas, salt of volatilization etc.) will be caught by the bag filter in sack cleaner Obtain, secondary flying ash typically may account for the 10% of the flying dust of input, in order to reduce the final disposal amount of secondary flying ash it would be desirable to essence Really control the furnace pressure of plasma melting furnace, part secondary flying ash is re-melted simultaneously, be so possible to by secondary flying ash Control eventually and put into 3% about (concrete numerical value is relevant with the component putting into flying dust) of flying dust.
Through the filtration of sack cleaner, flue gas becomes clean, thus being conducive to in salt acid generator recovered flue gas Hydrogen chloride gas.It is 22%~31% (wt/wt) by the concentration of hydrochloric acid that salt acid generator reclaims, its concrete numerical value depends on flying The setting value of content of Cl element and salt acid generator in ash.The flue gas discharged from salt acid generator top enters wet scrubbing tower Bottom, the SO containing in flue gas2Unabsorbed hydrogen chloride gas are neutralized by NaOH solution on a small quantity.Finally, dustless anacidity Clean flue gas first pass through steam heater heating and are incorporated to discharge after waste incineration main flue gas cleaning system is processed via air-introduced machine again. Flue gas to unsaturation temperature range, are made flue gas not produce white haze by steam heater.Summer outdoor temperature is higher, humidity Little, the concentration of white haze and diffusion area limited, can depend on the circumstances whether using steam heater, by arranging steam heat-exchanging Device bypass valve is controlling the opening and closing of steam heater.
According to the present invention it is possible to melt the incineration of refuse flyash being classified as hazardous waste, change into nontoxic glass Body and hydrochloric acid, farthest realize the minimizing of incineration of refuse flyash, innoxious and resource.
