Abstract
A process for treating the garbage dregs generated after burning features that the said garbage dregs are mixed with the solidifying agent prepared from light burnt magnesium, halogen flaks or powder, water and regulator, and the mixture can be used for backfill in engineering, brick, road, etc.
Description
Technical field
Refuse incineration slag disposal technology of the present invention and technology thereof relate to the technology and the product of a kind of disposal of garbage and regeneration.
Background technology
Can produce the slag and the flying dust of 25%～35% (weight percent) after the waste incineration, major part in the slag can be used as building materials after through correct the processing, according to German environment department 52 burning disposal factories are investigated, wherein there are 39 to be equipped with the slag treatment facility, have 38 incineration plant can utilize slag after nineteen ninety-five as road-making material.The waste incineration industry of China should be at the early-stage, particularly the lime-ash processing and utilizing after burning is not also had the technology of suitable moulding, down, presses for for burning slag roasting processing and research in light of this situation.
Summary of the invention
The object of the present invention is to provide and a kind ofly can be used for material of construction or as the refuse incineration slag and the preparation technology thereof of road foundation material.
The purpose of this patent can be achieved through the following technical solutions: a kind of refuse incineration slag, be that the refuse incineration slag fritter that forms certain particle size with deironing, broken back is a main raw material, the weight percentage of its each component is: refuse incineration slag 65～95%, solidifying agent 35～5%.
Wherein, described solidifying agent is made up of magnesia unslacked, halogen sheet or halogen powder, water and adjustment agent, and the weight percent of this solidifying agent is: magnesia unslacked 52～58%, halogen sheet or halogen powder 20～25, water 20～25%, adjustment agent 0.1～0.5%.This refuse incineration slag solidified solidifying agent has mainly selected for use low-cost ore deposit raw material light-burning magnesium powder and salt to pay product halogen sheet or halogen powder, and not only associativity is good, and low price.
MgO content in the described light-burning magnesium powder is 75～90%, the MgCl in described halogen sheet or the halogen powder
2Content is 42～46%.
Described adjustment agent is a kind of or several combinations in ferrous sulfate, copper sulfate, sal epsom, potassium permanganate, urea-formaldehyde resin, ammonium chloride, hydrochloric acid, phosphoric acid, the silicone emulsion.
Refuse incineration slag preparation technology is: with the water that accounts for solidifying agent weight part 20～25% halogen sheet or halogen powder are dissolved to the solution that degree Beaume is 23～25 degree earlier, add 0.1～0.5% adjustment agent then, again deployed solution is added to stir in the magnesia unslacked and makes solidifying agent, in refuse incineration slag, add the solidifying agent mixing and stirring at last and make.
Refuse incineration slag preparation technology also can be: with the water that accounts for solidifying agent weight part 20～25% halogen sheet or halogen powder are dissolved to the solution that degree Beaume is 23～30 degree earlier in changing stock tank, flow into and add 0.1～0.5% adjustment agent behind the former stock tank, 52～58% the magnesia unslacked of in the magnesia unslacked batch bin, pressing the solidifying agent weight part through feeding machine to grout mixer, simultaneously deployed solution is pumped into to stir the grout mixer from material-compound tank and make solidifying agent, at last components by weight percent 65～95% refuse incineration slags are added stirrer, 35～5% solidifying agent being pumped into stirrer simultaneously from grout mixer mixes and stirs, pour in-mold molding into or directly be transported to the construction site, pave, compacting.Technology of the present invention can be applicable to scale operation.
The purposes of refuse incineration slag of the present invention comprises: utilize refuse incineration slag to produce road foundation material and other material of construction.A kind of production technique that refuse incineration slag solidify is replaced Stabilized Soil and makes building materials is provided, and the different proportionings according to solidifying agent and refuse incineration slag are widely used in the engineering backfill, make clay brick, materials such as making roadbed, artificial hillock.For realizing that low cost, large-scale treating refuse burning slag provide a new approach.
Superiority of the present invention is effectively to utilize waste, becomes Fei Weibao, and production technique is simple and easy to do, and it can be widely used in the engineering backfill, makes clay brick, making roadbed, artificial hillock etc., is beneficial to environment protection.
