Description
The present invention relates to rubbish is transformed into a kind of method of grain shape material.More particularly, this method can be rubbish, particularly house refuse is transformed into not only anticorrosion but also water-fast hard particles, can be used for the production of the construction material such as brick or is used as concrete a kind of gathering materials of preparation.
As everyone knows, owing to also must prevent to pollute and other public hazards when removing ever-increasing rubbish of quantity and refuse, this problem more and more is difficult to solve.
For a kind of acceptable method that addresses these problems is provided, someone proposes, what pulverize in advance, the rubbish of having removed the metal that may comprise is transformed into a kind of solid that can be used as the various forms various sizes of construction material.
For example, French Patent (FRP) has been described the preparation method of solid block of material of the hard that can be used as construction material or packing material for No. 2098777: a kind of metal silicate is added in the rubbish of the non-classified pulverizing of a pile, in pressing mold this heap rubbish under high pressure being done compression handles, make piece material form, at last or at room temperature, perhaps under such as 80-200 ℃ of temperature, heat, the piece material is hardened.
French patent application has been introduced for No. 2286116 and a kind ofly have been prepared the method that the garden cartridge type gathers materials from the rubbish of having removed metal ingredient, drying and crushing, to replace the gravel by nature in the concrete production.According to an example implementing this method; the rubbish comminuted powder is with a kind of anticorrosion mashed protective agent such as metal silicate or furfural; a kind of adhesive such as a kind of synthetic resin; a kind of soluble asphalt or quick lime; ore slag and a kind of adhesive hardening catalyst mix; make thick paste, be pressed into garden tubular compression body through pressing mold, at last these compression body the highest be no more than to heat under 200 ℃ the temperature harden.
The method of the prior art of mentioning according to above-mentioned document is not entirely satisfactory, mainly be because these methods can not guarantee that gained solid (good mechanical performance is arranged) has high biologically inert and chemical inertness, can not guarantee simultaneously that the solubility in water is zero in practicality, and in use, be sought after these performances as construction material.
The objective of the invention is a large amount of rubbish is transformed into both anticorrosion, water-fast again hard particles in practicality.Used rubbish non-classified, only with known method with the metal ingredient that may contain in the rubbish, particularly metallic iron is removed, and pulverizes then.For this purpose, have the advantages that according to method of the present invention claim 1 is stated.
Therefore, according to the present invention, this method is based on following process, compression body (under pressure to mainly making by grinding up the refuse and containing the homogeneous mixture effect of granulating that the mineral material of calcium oxide forms) is heat-treated, these compositions are ground or pulverize make by particle and fibrous fine powder material, last fine powder material agglomerates into particle form.
People are surprised to find, the new compound mode of this operating process can not only be had high machinery resistance but also be had high chemical inertness and high biologically inert, the solubility almost nil particle of while in water, therefore these particles might be used for many various useful purposes, particularly produce construction material, and can not produce any pollution and other public hazards.
The mineral matter that contains free state or chemical combination attitude calcium oxide can be from such as quick lime, and calcite is selected in limestone and the clay product.
Grinding up the refuse and containing in the mixture of calcium oxide mineral matter, rubbish content is preferably 90-95% (weight), and content of mineral substances is 5-10% (weight).
And, the rubbish of pulverizing or the rubbish that grinds and contain the calcium oxide mineral matter mixture can with various fillers, particularly contain free state or chemical combination attitude calcium carbonate and magnesium carbonate mineral matter, such as dolomite, mix.
Implement the different operating of the inventive method, can carry out, particularly use known technology and conventional equipment disposal of refuse with any suitable method.
Distinguishingly, in order to obtain in fact not containing the rubbish of metal ingredient, can use rubbish in the collecting box or refuse through common classification, the operation of sieving, can reclaim and/or reusable object, particularly bulk metal so that therefrom tell.
After this, in order to make rubbish become the even pulverulent mixture that does not in fact contain metal material (particularly iron), can pulverize and married operation rubbish at the same time or separately, when possible, with one or more be intended to isolate metal derby particularly the sort operation of iron content fragment combine.For example classified rubbish is carried out elementary coarse crushing, make about 50 millimeters of fragment mean size, this crushing operation is to carry out before or after for the magnetic classification of removing abrasive grit and other ferrimagnets.For example utilize rotary hammer, pulverizer or shredder to carry out the second time then and pulverize, so that rubbish becomes maximum gauge less than 20 millimeters the particle or the particulate of fibers form.
The married operation that grinds up the refuse in a large number and contain the calcium oxide mineral matter also can use any proper technology and equipment, particularly uses measurer and can be continuously or the automixer of intermittent running.
Prepare compression body by the mixture that grinds up the refuse and contain the calcium oxide mineral matter, can use the rotation granulation device of being furnished with roller and pressing mold (such as, produce the equipment of animal feed granulate), under the pressure of 150-900 crust, granulate, for example make that length is the 5-60 millimeter, diameter is the garden tubular compression body of 2-20 millimeter.
Preferably compression body is axially carried out the heat treatment of compression body by the tubular type rotary kiln with feathering axis, said kiln is by hot air, and its inside has spiral wall to guarantee the circulation of compression body.Especially, the kiln or the stove that can use thermal air current to pass, thermal air current is heated to 250-400 ℃ of temperature range with burner, and its flow direction is consistent with the flow direction of compression body.
The effect of this processing is that the content of water in the compression body is reduced to for example 5% (weight), and is converted into the hardness of the carbonization increase compression body of calcium carbonate by calcium oxide.After super-dry and sclerosis, compression body can especially, use dismountable beater grinder that has screen cloth (material crushed is passed through) to pulverize with any suitable method.What obtain like this is the segmentation material of the granular solid matter that is obtained by comminution of minerals matter (in the rubbish such as glass, lime stone etc. or organic substance) of the fibrous material (by getting such as textile, plastics and cellulosic material in the initial waste) that contains a certain ratio and a certain ratio.The length of fibrous material or the pulverizing by changing compression body or to grind conditioned disjunction be that subsequent operation by adjusting fibre length is as the screening operation, adjust, make most of fibre lengths in given scope, preferably between the 0.1-30 millimeter.For example, when pulverizing compression body,, can adjust the length of fiber, synthetically say the size that to adjust the segmentation material by fineness such as the 1-4 millimeter of selecting suitable grater screen cloth.
The material of segmentation group (pulverize or grind make compression body) is carried out agglomeration to be handled and makes particle, can use any suitable method, for example a kind of method can be used drum-type and disc type agglomerating device, also can be used in combination this two kinds of devices.
Before agglomeration is handled, preferably in the material of segmentation, add at least a adhesive and at least a mineral filler.
As adhesive, preferably select the calcination ash or the ferrosilicon powder of water cement or cleaning sludge for use.As mineral filler, can use for example calcium carbonate, powdered lime stone, hydraulic lime can use the lime-ash that reclaims in the building material apparatus, also can use the lime-ash in other industrial equipments.
For the mixture agglomeration of the material agglomeration that makes segmentation or the material that makes segmentation, adhesive and last filler, be preferably in agglomeration handle before or in the agglomeration processing procedure, in the material of segmentation or mixture, add a certain amount of water.
For example, can be with the form that forms homogeneous mixture in blender, adding adhesive, possible mineral filler and water by granular solid matter and the fibrous material of forming, blender places before the agglomerating device.Homogeneous mixture also can form in the agglomeration treating apparatus.As a kind of selection, also can add adhesive and last mineral filler to material by granular solid matter and fibrous segmentation, blender (before being arranged in the agglomeration treating apparatus), form elementary homogeneous mixture, and the water of adding capacity makes the mixture agglomeration in the agglomeration treating apparatus.
Admire the clear Xia Liang of oar good fortune according to another stool ┍ convulsion green pepper mother ǖ and be coated with why not shrimp of a rough bamboo mat a unit of weight used in ancient China, equal to six liang and slough off bright meaningful water and mix, the mixture that so obtains and introduce granulation device simultaneously by granular solid matter and fibrous mixture at blender (before being arranged in granulation device).Improve this method operation scheme according to another one, the homogeneous mixture of the material (by granular solid matter and fibrous) of segmentation and adhesive and mineral filler, can prepare as in the drum-type granulation instrument of blender at the same time, the water that adds above-mentioned amount then makes mixture agglomerate into particle form.Rotating cylinder turns round in the mode that forms particle.Then formed particle is changed over to board-like granulation device, finish agglomeration there and handle.For example, can supply with the homogeneous mixture of adhesive and mineral filler to granulation device, perhaps or even adhesive, mineral filler and by the material of the fibrous segmentation of granular solid matter, increasing primary particles, and generate the particle that the shell that is different from kernel by a kernel and composition is formed.This particular processing can obtain having one than the kernel particle of hard shell more.
Preferably make further cure process to handling the particle that obtains by agglomeration.For example, (its condition depends on the performance of the material that constitutes particle to cure process, mainly be the performance that depends on adhesive therefor) comprise a kind of operation at least, promptly particle is carried out high pressure, heating or decatizing, perhaps two kinds in conjunction with above-mentioned three kinds of factors act on.Clearly, aforesaid operations can be operated combination with another kind, makes to have the particularly particle of composite construction of ideal structure.
Example 1
