Abstract
The innocent process of treating fly ash from burning domestic garbage and industrial refuse permanently belongs to the field of environment protecting technology and hazardous waste stabilizing treatment technology. Fly ash is first mixed with soluble silicate in 5-8 wt% of the fly ash, fine active silica powder in 3-5 wt%, kaolin in 15-20 wt% and water; and the mixture is cured, dried to water content lower than 10 % and finally melted at high temperature. The innocent process is superior to other processes, and has the advantages of complete treatment, no secondary pollution, high value of the product and complete elimination of heavy metal harm.
Description
Technical field
The present invention relates to the permanent innocent treatment method of domestic waste, hospital refuse, industrial refuse and incineration fly ash, belong to environmental protection and stabilization of dangerous waste materials treatment process technical field.
Background technology
Waste incineration is main means handling domestic waste and hospital refuse, industrial combustiblerefuse, burning process will produce the flying dust of quantity of refuse 3-5%, contain heavy metals such as a large amount of lead, cadmium, copper, chromium, zinc in these flying dusts, also rich have noxious materials such as the dioxin of carcinogenesis and furans to human body.The flying dust recycling concentrates on both at home and abroad: flying dust and end slag mix to be made as eco-cement, flies the alternative inserts of slag as cement concrete and bituminous concrete with bottom ash; Devitrified glass is made in the fusion of simple flying dust, makes the filler of plastics after the flying dust modification.The deficiency that exists is, flying dust resource cost is too high, heavy metal ion after the resource in the flying dust leaches and causes environmental pollution, get back in work as plastics inserts heavy metal that secondary becomes danger in the flying dust in the waste incineration again, easily be used to daily necessities with the plastics of modification flying dust filling and bring insecurity to people.
Summary of the invention
The present invention is just in order to overcome above-mentioned deficiency, a kind of domestic waste is provided, the permanent innocent treatment method of industrial refuse and incineration fly ash, normal temperature is down with soluble silicate modification flying dust, make heavy metal become water-fast silicate, at high temperature generate silicate with active silica fume and heavy metal reaction, generate glass with the fusing of low melting point kaolin again, make flying dust thoroughly innoxious, specifically implement like this: domestic waste, the permanent innocent treatment method of industrial refuse and incineration fly ash, it is characterized in that flying dust is added soluble silicate, active silica fume, adding water behind the kaolin mixes, curing is dried to moisture content and is lower than 10%, the final high temperature fusing, described soluble silicate, active silica fume, kaolinic addition is respectively the 5-8% of flying dust weight, 3-5%, 15-20%.Water-fast silicate is produced in heavy metal in the flying dust and silicate reaction, after treating that the flying dust mixture solidifies drying, pass through high temperature melting again, further allow heavy metal fully with silicate, active silica fume reaction generation silicate, and melt generation glass with kaolin, make heavy metal fully by vitrifying, thoroughly solve its harmfulness.
In order to reduce cost, the kaolin that the present invention selects for use is to be lower than 1200 ℃ low melting point kaolin, and high temperature melting is then carried out in the stove that carries out more than 1200 ℃.
The flying dust mixture adds water and mixes and can carry out in the vacuum muller three to five minutes, fully stir mixed after, solidify and generally use the de-airing extruder extrusion modling, drying is carried out usually under field conditions (factors) or in the drying room.
Flying dust liquation after the vitrifying of the present invention obtains silicate fiber with getting rid of a method production, can be widely used in the insulation material below 350 ℃ in the process industry production, also can cool off the substitute that stone, inserts are used as in the back fragmentation.
The present invention adds soluble silicate in flying dust, active silica fume, kaolin, carry out earlier stabilization processes at normal temperatures, congruent melting at high temperature generates a kind of processing method of low temperature glass then, compare with other flyash treatment methods, have and handle thoroughly, non-secondary pollution, added value of product height during batch process, the permanent heavy metal danger that is harmful in the flying dust that solved, after testing, in the flying dust product after the present invention handles, lead, zinc, cadmium, nickel, barium, fluoride, oxide, chromium, arsenic, the leaching solubility of mercury heavy metal ion is all far below state's standard, wherein fluoride, barium, nickel, cadmium, lead all can not detect.
