Technical field
The present invention relates to a kind of method of manufacturing regenerated construction material, particularly relate to a kind of with end slagFine aggregate is manufactured the method for regenerated construction material.
Background technology
Garbage disposal is the great environment class facing after mankind's intense industrialization and urbanizationTopic. In numerous trash processing way, after first with incinerator, incineration firing being incinerated, add againCurrent wide adopted a kind of trash processing way to process. Burn to process with incineratorRubbish at least has following several benefit: (1) rubbish is after burning is incinerated can be by rubbishVolume reduces significantly; (2) contained in rubbish have the material of harm to fire by incinerating to environmentBurn and removed; (3) burning of incinerator is to implement under the environment of controlling, its emission gasesAlso be subject to suitable monitoring and processing, can reduce the harm to human body; And (4) burning after the endThe recyclable recycling of slag, to improve the economic benefit of garbage disposal.
Through incinerating after operation, the thing that residues in incineration siege is end slag (BottomAsh).The end slag handling procedure of taking is at present first to be stored after end slag, then the sorting of sieving,After the choosing of magnetic separation, vortex flow, the step such as broken to obtain needed product. End slag is via upperState after treatment step, can use according to different demands the pellet of different-grain diameter, and particle diameter is less thanThe pellet (being commonly referred to as fine aggregate) of 1mm can be passed into disuse conventionally. But, above-mentioned fine aggregateBe similarly dealer's Expenses Cost and process the product after end slag, add utilization if not kind, quite unfortunate.

Detailed description of the invention
The embodiment that the present invention manufactures the method for regenerated construction material with end slag fine aggregate comprises following stepRapid: incinerator bottom slag to be collected and carried out wet type screening, magnetic separation, eddy current separation, stirringWashing, and after silt particle separation, collect the fine aggregate that slag particle footpath, the end is less than 1mm.
Wherein, what wet type was screened is to be arranged in a rotary screen for water unit one,When screening rolling in rotary screen wash away end slag with water jets under high pressure. See through water jets under high pressureThe mode of washing away can make organic matter in end slag and chlorion water-soluble and be pulled away,Water under high pressure note also can wash away the sieve aperture of rotary screen simultaneously, avoids sieve aperture stopped up and fall by end slagLow screening effeciency. Owing to being not the emphasis of this case for the structure of water unit and rotary screen, no longerRepeat.
Through after wet type screening, in magnetic separation mode by filtering out ferrous metal in end slag and delivering toFerrous metal accumulator tank is recycled, then selects containing non-iron gold in eddy current separation modeBelong to. Eddy current separation is to utilize the change in magnetic field by nonferrous metal and other component separation,The flow path of vortex flow must be closed curve, and its flow direction is parallel with coil winding direction,Vertical with alternating magnetic field direction and be rightabout stream with the change of flux of alternating currentMoving, so its frequency is identical with the frequency of alternating current. Can induction excite the object of vortex flow mustBelong to the conductor that can conduct electricity. Utilize this principle will comprise the sorting from end slag of the metal such as aluminium, copperOut, to improve recovery value and to reduce secondary pollution, slag of the remaining end carries out next step.
Then end slag is stirred to water by roller washing equipment in the mode stirring of rollingWash. In the present embodiment, stir end slag that the water yield that uses of washing and wish washWeight ratio is 2:1 to 5:1, and stir washing time be 2 to 5 minutes. ?Stir in the process of washing and allow end slag rub each other and wash by rubbing with the hands, not only can promote washing effectRate, also can make the impurity being attached on end slag be removed in the process of washing by rubbing with the hands, makes the endSlag outward appearance more approaches natural sandstone. Moreover, stir in the process of washing and can again make the endOrganic matter in slag and chlorion are water-soluble and be pulled away. Finally by the end of stirring after washingSlag carries out silt particle separation, collects the fine aggregate that slag particle footpath, the end is less than 1mm.
Fine aggregate is mixed with glass fibre and calcium/silicon additive (Ca/Si) carry out modified, itsIn, the percentage by weight of fine aggregate is 10 to 40%, the percentage by weight of glass fibre is 2To 15%, the percentage by weight of calcium/silicon additive is 50 to 80%. By the thin collection after modifiedMaterial is mixed to form compound with water, and water-solid ratio (W/S) is controlled to 1.35 to 1.55.Wherein, calcium/silicon additive is to be selected from cement, lime, silica sand or a combination wherein.
Table one is the characteristic of board product under different glass fiber addition. Can by result of the testKnow, along with glass fibre addition improves, the bending strength of sheet material is along with improving (according to " buildingBuild with plate class bend test method CNS3904 " standard method tests). When glass fibre addsWhen dosage arrived weight percentage 8%, bending strength reaches as high as 10.1N/mm2. Work as glassWhen fiber addition overweight percentage 8%, bending strength starts to reduce, therefore known glassGlass fiber addition should be best process conditions while being 8%.
Table one
By three tables of table two, be 8% at glass fibre addition again, calcium/silicon addsMaterial ratio is 0.83, and water-solid ratio is 1.45 o'clock, can obtain best bending strength, because ofThis summarizes better parameter proportioning of the present invention is water-solid ratio 1.45, and calcium/silicon additive ratioBe 0.83.
Table two
(1) water-solid ratio=1.35
(2) water-solid ratio=1.45
(3) water-solid ratio=1.55
Finally compound is gone out to sheet material with specified pressure extrusion forming, and by sheet material at 12 atmospherePressure (atm), 190 DEG C, carry out the autoclaving of 16 hours, can obtain Regenerated plateMaterial.
In sum, the present invention makes full use of the discarded fine aggregate of former background slag meeting after treatment,Go out standard compliant regenerated construction material through modified effect aftershaping, if end slag processing procedure is takenJoin the program of stirring washing, allow end slag rub each other and wash by rubbing with the hands, can make to be attached to the endImpurity on slag is removed in the process of washing by rubbing with the hands, and allows end slag outward appearance more approach natural sandstone,Further promote the quality of regenerated plates.
