Description
Technical field
The present invention relates to a kind of sintering feed or waste material or refuse of using and prepare the method for construction material, relate to the method that a kind of flying dust that utilizes consumer waste incineration to produce prepares the architectural coating brick in particular as mortar, concrete or artificial stone filler.
Background technology
Domestic garbage incineration flyash is a kind of generally acknowledged hazardous waste, has wherein concentrated a large amount of heavy metals and has included a spot of hypertoxic dioxin organic matter, and China GWKB3-2000 expressly provides that flying dust is that a kind of hazardous waste must carry out harmless treatment.But flying dust is again a kind of resource, contains more silicate, aluminate in the flying dust, can be used as the admixture of construction material; Vitreum and many active network activated metal ions more in the flying dust make that again flying dust has certain activity; In addition, the particle diameter about flying dust 200 orders is formed the activity that has also increased flying dust, can save the energy consumption in the resource process.At present, the research that flying dust is handled disposal both at home and abroad mainly concentrates harmless treatment formerly to advance on the landfill yard landfill again, and the research of utilization of relevant flying dust seldom.
The development of garbage incineration technology makes the discharge capacity of domestic garbage incineration flyash increase year by year, in Shanghai, after the existing all the people present's incineration plant in Shanghai all put into effect, a day disposal of refuse amount reached several kilotons, and the ash discharge amount is if calculate then four factories day ash discharge amount up to the hundreds of ton according to 2~4%.The main processing method of flying dust is to solidify to insert the hazardous waste landfill yard then at present.Solidification process has not only been wasted many cement-based materials, and solidifies the back volumetric expansion, has increased space shared in the hazardous waste landfill yard; The high cost that hazardous waste landfill yard administrative expenses quite high (being 2,700 yuan/ton at present), flying dust enter the processing of hazardous waste landfill yard has caused very big burden to finance; The flyash curing body of inserting the hazardous waste landfill yard can not recycling, has caused the waste of ample resources; From long-range angle, flying dust advances landfill yard also can cause secondary pollution.This shows that it is a kind of temporary transient safe but costly method that flying dust is disposed in the hazardous waste landfill yard.In addition, China gives birth to the construction speed of the construction speed of suitable garbage burning factory considerably beyond the hazardous waste landfill yard at present, and every day, a large amount of flying dusts was all waited safe handling.Domestic only in Shanghai, several urban construction such as Shenzhen, Shenyang satisfy the hazardous waste landfill yard of technical specification, and the landfill ability of the landfill yard of building and service life also are limited.It is extremely urgent to seek more economical rational flyash treatment method thus.
The method of disposal of flying dust recycling has: curing/stabilizing comprises cement solidification, bitumen solidification, chemical agent stabilisation etc.; High-temperature process comprises sintering and fusion/vitrifying etc., inserts special landfill yard or recycling then; Extract the heavy metal in the flying dust, comprise that acidleach is got, biology and biologic product extractions, high temperature extraction etc., then with the heavy metal resources utilization of extraction.Wherein the high-temperature process technology be at present unique can destroy dioxin and other toxic organics the flying dust treatment technology, can be divided into: glass solidification (vitrification), fusion separate (fusion) and sintering (sintering).It is that flying dust is heated to melt temperature (1,200~1,400 ℃) that fusion separates, lower boiling heavy metal and salt will be evaporated to gas phase after the fusion, collected by the exhaust dust-precipitating system, difficult volatilization heavy metal separates recyclable utilization because of the bottom that the big part of density sinks to smelting furnace; Another part then residues in the slag.Form glass state material after slag quenches, can be used as building materials and use.The fusing fly ash treatment technology is most widely used in Japan, and at present nearly 4% lime-ash adopts fusion method to handle, and in the incineration residue fusion factory that builds He moved 21 families is arranged approximately by 1999.Though simple fusing fly ash technology can obtain certain appearance solidification effect that subtracts, but because the hardness of gained vitreous material, hot property etc. are relatively poor, thereby limited its application in fields such as construction materials, usually can only be used for the composite material of roadbed material, cement concrete or send into the landfill yard landfill once more, added value is lower; Can produce the melting furnace flying dust (its Cd and Pb concentration are 5-10 times before the fusion) of a small amount of high concentration in the melting process again; The expense of fusing fly ash is also very high, is difficult in the whole world promote.Glass solidification is that the mixture with flying dust or flying dust and frit is heated to 1, melt temperature more than 000~1,200 ℃, and the atmosphere of control smelting furnace prevents the volatilization of heavy metal, melt substance quenches and forms glassy state, thereby harmful substance is cured in the pollution of having avoided in the glassy state environment.People such as Young Jun Park add in flying dust behind the 5%SiO2 1, fusion 30min under 500 ℃ of high temperature, after treating the physics and chemical state change of flying dust, cooling makes it solidify to form the glass solidification body, by Vitrea compact crystal structure flying dust is enclosed in the vitreum securely.The Vitrea dimension formula intensity of gained is 4,000~5, and 000MPa, rupture strength are 60~90MPa, and fracture toughness reaches 0.9MPa m1/2, fully can recycling.This kind processing method has good loss of weight, subtracts the appearance effect flying dust, because chloride is gone up all substantially and evaporated 1,500 ℃ the time, flying dust generally can loss of weight about 2/3.Heavy metal is strapped in the network structure of SiO2 silicon-oxy tetrahedron composition securely after the fusion simultaneously, and leaching rate is very low, can satisfy present leaching standard.But power consumption is up to 600~1,250kWh/t, and produced the flue dust that contains plurality of heavy metal and sour gas in the melting process, and increased the system handles expense, make disposal cost up to 166~500 dollars/t, have only economically developed country scale to use.In people's such as T.Mangialardi the research flying dust being pressed into the bottom surface diameter is 15mm, height is the small cylindrical base substrate of 20mm, then 1,140 ℃ high temperature is calcining 60min down, the compression strength of sintering curing body reaches 28N/mm2, satisfy the requirement of Italy to coarse aggregate intensity in the concrete, therefore this flying dust sintering curing body can be used as the admixture in the concrete.But this method requires flying dust to carry out preliminary treatment through washing, otherwise the sulfate in the flying dust, villaumite and vitreum are totally unfavorable to the sintering curing process.1,140 ℃ calcining high temperature makes the energy consumption of this processing method and expense very high, and the firming body of calcining gained just uses as coarse aggregate, is worth low cost in can not the compensation deals process, is the method for the low output of a kind of high energy consumption; In addition, produced secondary pollution in the water-washing process again, increased the burden of environment, therefore the angle from sustainable development is a kind of worthless method.People such as A.polettini have done further research on the basis of T.Mangialardi sintering processing method, added additives such as cullet and some ores and excite the activity of flying dust in flying dust, the result has calcined out performance better flying dust sintering curing body and need not wash preliminary treatment.But its calcining heat is still up to 1,100~1, and 150 ℃, energy consumption is very high, is difficult to promote.And gained sintering curing body can not directly be used as building materials, can only be used as concrete admixture, and economic benefit is lower.The method of above-mentioned flying dust resource all is to consider to sinter flying dust into concrete aggregate, and not only the energy consumption high production is low, and the volatilization of heavy metal is very serious under high-temperature calcination, causes secondary pollution thereby the concentration of heavy metal is very high in the discharged flue gas; Gained sintering curing body is in case damaged in addition, and the heavy metal that is included in the inside will leach in suitable environment, causes environmental pollution.
