Description

The processing of material

The present invention relates to the processing of material, as destroying toxic waste, it had both comprised that method also comprised device.It is very easily that the embodiment of reference degraded waste material specifically describes the content that the present invention relates to.

The present invention be more particularly directed to but be not only to relate to by chemical process, chemical conversion and the similarly processing of the discarded object that produces of process thereof, these products usually comprise severe toxicity, cause physiologically active or carcinogenic material.For example, comprised chlorine or polychlorostyrene in these products and crossed fluorine or poly-fluorine aliphatic material or aromatic substance, as: these compounds of chlorophenol, dioxin and furans usually also show very high anti-chemistry and hear resistance except that having toxicity.

Refuse destroys has become a most important problem in the worldwide, has invented two kinds of methods of removing noxious material, i.e. soil landfill method and high temperature incineration method.

In the soil landfill process, only apply to solid usually, noxious material is not decomposed, but leaves in the heatable adobe sleeping platform simply.Designed heatable adobe sleeping platform preferably can prevent by the caused underground water pollution problem of waste material of placing wherein.For certain areas, this technology just is unsuitable for adopting, and for example, exists dangerous area such as leakage, seepage.

In high temperature incineration technology, common available temperature is for example up to 1500 ℃, and this temperature is not enough to decompose all noxious materials, and the noxious material that heat endurance is the strongest will be discharged in the atmosphere like this.In addition, burning process also can impel other De bioxin of generation and furans, so they also can be discharged in the atmosphere.

All there is shortcoming in each method described above.

The purpose of this invention is to provide a kind of improved material processing method and device.

Another object of the present invention provides a kind of method of effective and easy destruction toxic waste.A further object of the present invention provides a kind of suitable refuse degraded equipment.Another object of the present invention provides a kind of method of refuse degraded and the equipment of implementing this method, the scene that this equipment can be used for or close waste material produces.

Material processing method of the present invention is characterized in that material is introduced a pyrolysis apparatus, high-temperature process a period of time, be enough to realize basically degrading fully, and then, make material leave pyrolysis apparatus, and experience a rapid quenching process.An aspect of this method is that the material after making chilling enters in the facility, is attracted on the solid carrier material at this residual toxic compounds, so that they and material main body can be separated.

Best above-mentioned solid carrier material is a granulated carbon, and best above-mentioned carbon is to handle in the process of refuse material to form in pyrolysis apparatus.

Processed material can be liquid formula, and it is atomized when introducing pyrolysis apparatus.In addition, material also can be solid particulate form or gaseous form.

Preferably pyrolysis apparatus comprises a high energy electric heating plasma, in the material injected plasma that has atomized, is deconstructed into the molecule of material with branch.This degradation speed should be controlled by means of the temperature of plasma, and is controlled at least in part.Preferably material leaves plasma arc with the form of fluid, passes a hot-zone, and in this hot-zone, material temperature remains on sufficiently high scope, with the pyrolytic process of proceeding to begin in plasma.As realizing in the described several method hereinafter.Determine the time of staying in the hot-zone, so that the possibility that all molecules decompose fully in the increment materials flow body, a kind of heated time of special material is long more, and the possibility of this high temperature resistant substance decomposition is just big more.Usually, temperature is high more, and the speed that decomposition is carried out is just fast more.

The material fluid leaves after the hot-zone, makes the material cooling in the cooling zone with a quenching process, and the speed of chilling is preferably suitable, to prevent dissociated ion chemical combination again, perhaps is reduced to minimum degree at least.

As mentioned above, residual toxic compounds can be separated from the material fluid by being adsorbed on the granulated carbon, decomposes these residual toxic compounds by this granulated carbon is further handled.

A kind of best way of this method is to limit a hot-zone mentioned above with a pipe (hereinafter claiming the stroke pipe), and the material fluid passes this pipe and enters the cooling zone from plasma arc.The material fluid preferably directly enters this pipe after ion plasma flows out.The diameter of stroke pipe and structure have certain influence to the efficient of this method, and this point hereinafter will be discussed.

As mentioned above, the pyrolysis meeting of material such as refuse material produces granulated carbon, and as carbon black or activated carbon, these particles can influence the subsequent treatment of material, and for example, these particles can stop up or part is stopped up the stroke pipe.When processed material mainly comprises hydrocarbon especially this situation can appear.Yet, when the main oxygen containing organic compound of material, the problem of too much granulated carbon can not appear producing.

An aspect of this method is to inject oxygen in plasma, makes it and the granulated carbon phase reaction that may generate, and produces the carbide of gaseous state thus, and simultaneous is emitted heat.Therefore, this additional oxygen can reduce the concentration of solid carbon in the material fluid, makes follow-up material handle easier carrying out, and for example makes the material fluid pass the one stroke pipe.In addition, the heat that discharged helps temperature maintenance with the material fluid in sufficiently high scope, so that when material flow is crossed the stroke pipe, stops the poisonous compound of chemical combination generation again.

By the processed material of dilution in an inert carrier liquid, solid carbon changes into gaseous carbide, and the amount that need add oxygen in processed material can be cancelled or be minimizing at least.Can not influence reaction power when this inert carrier liquid is flowed through device, carrier liquid can reduce the weight percent concentration from granulated carbon in the isoionic material fluid effectively.More ideally, should control the addition of inert carrier liquid, be reduced to a suitable concentration, promptly not add the concentration that any oxygen also can avoid device to stop up with weight percent concentration with granulated carbon.

In some cases, may stop up or part is stopped up other devices of cooling zone and/or back, cooling zone as the concentration of granulated carbon from the material fluid that the stroke pipe flows out, although as mentioned above, add oxygen in plasma, this situation also can occur.For overcoming this problem, a kind of method of the present invention is to add oxygen again in the fluid that flows out the stroke pipe, makes it and granulated carbon phase reaction, reduces the concentration of granulated carbon in the material fluid thus.The reaction of oxygen and carbon is exothermic reaction, and institute's liberated heat helped before the material fluid is carried out chilling, with the temperature maintenance of material fluid in a suitable high temperature.This high temperature can suppress ion again chemical combination form poisonous compound.Best, a very rapid thermograde is provided in the cooling zone.

Enter in the alkaline solution through cooled material, impel the toxic compounds of acidic residues to be adsorbed on the carrier mass, for example on the granulated carbon.Like this, escape from the toxic compounds of pyrolysis apparatus, perhaps the toxic compounds that forms of chemical combination again after pyrolysis apparatus, can been separated on the granulated carbon,, these particles can be separated from the material to be processed of remnants with any suitable device, for example, separate by filtration.

Can further handle the granulated carbon of separating that is adsorbed with toxic compounds,, for example, these particles be handled, be drawn onto in the liquid, subsequently this liquid be looped back in this flow process so that toxic compounds is separated with the toxic compounds that dissociates out.

Go up the aspect in addition, also can dispose these granulated carbon, under any circumstance, adopt which kind of method to depend on the concentration of toxic compounds on the granulated carbon usually with the mode of soil landfill.

Another aspect of the present invention has provided a kind of equipment for treating materials, this equipment comprises a pyrolysis apparatus, this pyrolysis apparatus has the device of a generation plasma arcs, a device that outside above-mentioned arc district, holds plasma, and one introduced device in the above-mentioned pyrolysis apparatus with the tiny spray of material and/or gas form, this material input unit is positioned at or is close to the zone at above-mentioned arc place, above-mentioned pyrolysis apparatus has a material outlet, with a quenching apparatus, this quenching apparatus is positioned at or contiguous above-mentioned exit.

With reference to the accompanying drawings will embodiments of the present invention is described in detail, however accompanying drawing can only illustrate how the present invention uses, and can not and arrange with the special construction of various features shown in the accompanying drawing to limit protection scope of the present invention.

Fig. 1 is the flow chart of a kind of method of the present invention.

Fig. 2 is the constructed profile that is used in a kind of pyrolysis apparatus in the flow process as shown in Figure 1.

Fig. 3 is the cross-sectional view of the semi-schematic of the stroke pipe in the equipment that is used in as shown in Figure 2.

Fig. 4 is the cross-sectional view of the semi-schematic of the another kind of stroke pipe in the equipment that is used in as shown in Figure 2.

What Fig. 5 represented is the schematic diagram of using equipment in one embodiment of the invention.

Among Fig. 1, the pending material of line 1 expression is sent into the path in the pyrolysis apparatus 2, can material be sent in the pyrolysis apparatus 2 with any suitable form, but preferably with the tiny spray of liquid and/or the form of solid particle, or with gas form, the form that perhaps this tiny spray combines with gas.In addition, preferably under certain pressure, material sent into pyrolysis apparatus 2.

In fact, material is mobile along path 1 with the form of liquid fluid, and this liquid fluid can be atomized at injection pyrolysis apparatus 2 places, or directly is atomized before injecting pyrolysis apparatus 2.Can adopt any suitable nozzle or other devices during atomizing, best, the diameter of the drop that atomizing produces is 100 microns or littler.Especially, drop should be enough little, so that drop can obtain pyrolysis up hill and dale.If drop is too big, under the condition in pyrolysis apparatus 2, the drop surface can only be by charing.

If enter the material of pyrolysis apparatus 2 is the form of solid particle spray or the spray that comprises, and so for above-mentioned reasons, the size of these solid particles should be enough little.Usually, to be less than or equal to 100 microns be gratifying to the diameter of particle.

Pyrolysis apparatus 2 comprises a device 3 that produces plasma arcs 4, so that can produce a high energy electric heating plasma.Pyrolysis apparatus 2 also comprises a hot-zone 6, and it is right after plasma arcs generating means 3.The material fluid that flows out from plasma arcs generating means 3 enters the hot-zone 6.

Plasma gas 7 is the mixture of argon gas or argon gas preferably, so that produce an inertia plasma atmosphere, in this atmosphere pyrolysis takes place.For example, plasma arcs generating means 3 can be a plasma torch, same or similar with the disclosed plasma torch of PCT patent application AU89/00396, aspect temperature, the temperature of plasma is usually 10,000 ℃～15, in 000 ℃ the scope, in addition, can also use the plasma of other form, as: plasma flow.

The direction that processed material enters plasma arcs 4 can choose in advance, or according to circumstances decides, and for example, usually direction should be parallel to the arc direction of arc 4, and perhaps transverse to the direction of camber line, but the latter is better usually.

Best, in processed material enters pyrolysis apparatus 2 zones of plasma, keep suitably high temperature, for example, 1000 ℃ or preferably higher.Can perhaps answer the abutment, downstream 8 of arc of approach 4 at least directly with the heart portion of material injected plasma arc 4.If it is impossible directly to inject, tackles jet pipe 3 surfaces of material input area so and heat, so that temperature remains in the suitable high scope.

Fig. 2 clearly shows the optimum position that processed material is introduced the point 9 of pyrolysis apparatus 2, as shown in Figure 2, single jet pipe 3 has been formed the part of pyrolysis apparatus 2, jet pipe 3 comprises a negative electrode 10 and two anodes 11 and 12, two anodes are separated by row's dividing plate 13, and anode 11 is the initial anodes that produce arc 4, in case produced arc 4, it just extends, thereby makes its abutment, downstream 8 be on the anode 12.Can also adopt the jet pipe of other form.

In special tectonic as shown in Figure 2, processed material or the position at arc of approach abutment 8 inject the passage 14 of jet pipe, injection direction is usually transverse to the longitudinal axis of passage 14, makes the core that is easy to material is injected into arc 4.

Cause decomposition under the high temperature action of molecule in the material that is injected in plasma, make material thus by pyrolysis, or at least basically by pyrolysis.From the material of plasma arc 4, enter and pass hot-zone 6 with the form of fluid 5, material fluid 5 mainly is a gas, and the particle of the solid carbon that exists with the carbon black form of dispersion is wherein arranged.

In special tectonic as shown in the figure, hot-zone 6 is formed by a long and narrow hollow tube, hereinafter will call the stroke pipe to this pipe.The effect of pipe 6 is extendible nozzle passages 14, and the diameter of pipe 6 should selectedly make it be fit to special requirement and situation.Pipe 6 basic function is that the continuation pyrolytic process for material fluid 5 provides a container, that is to say, not by the material of pyrolysis fully, the effect of pipe 6 provides an environment of proceeding pyrolysis in jet pipe 3.Especially, pipe 6 has prolonged the time of staying of material in enough hot environments, therefore for realizing that complete pyrolysis provides maximum possibility.

In the satisfied a kind of structure of operation, the stroke pipe is elongated its diameter and about 2: 25 of the ratio of length.Yet under some special situation, can select the length of selecting pipe else, obtaining material suitable time of staying in pipe, and any suitable diameter and length are than all adopting.The character of toxic compounds time of staying that will influence material in pipe 6 determines in the material to be processed.

Design pipe 6 o'clock, problem that needs emphasis to consider was the length along pipe, material to be processed is remained under the hot conditions as much as possible, to prevent undesirable reaction of recombination.On temperature, the temperature that enters pipe 6 fluid 5 can surpass 3500 ℃, the temperature of the fluid in pipe 6 can be for 1200 ℃ or 1200 ℃ about.

Because the cause of contact, thing grain fluid will be cooled with the contacted fluid boundary layer of pipe 6 circumferential surface.Therefore manage 6 and should be designed to be the boundary layer and can control, make its thickness thin as much as possible.Especially wish, when material when the outlet 15 of pyrolysis apparatus 2 is flowed out, the temperature of material fluid is constant basically.

A kind of scheme that realizes above-mentioned requirements as shown in Figure 3, the inner surface of stroke pipe 6 has one group of protuberance 16, it makes the axle center of the boundary layer skew reflux of material fluid 5, the turbulent flow that produces has suppressed to form significantly cooling boundary layer, the boundary layer is constantly mixed with the fluid of inner relatively hot, make that thus temperature remains unchanged basically on the whole width of fluid.

Fig. 4 has represented another embodiment, in the pipe 6 one deck lining 17 is arranged, and this lining can be stood high temperature, especially the temperature more than 1000 ℃.As a kind of embodiment, lining 17 can be made of a kind of ceramic material, and if desired, this structure can also be improved by upward adding an external heat source to lining 17 in place, as near the outlet 15 of pyrolysis apparatus 2.In addition, the tube wall 18 of the pipe 6 around the lining 17 can also cool off by (for example) water, and water enters by import 19, flows out by outlet 20 again.Equally, in other forms of pipe 6, may also wish to cool off, comprise form as shown in Figure 3.

As previously mentioned, from the material fluid 5 that jet pipe 3 flows out, contain the particle of carbon, higher if the concentration of carbon granule compares, the danger of stopping up pipe 6 will be arranged.For fear of this problem,, make the particle of some carbon change into the carbon compound of gaseous state to one Oxygen Flow of pyrolysis apparatus 2 input.In special case as depicted in figs. 1 and 2, introduce in material to be processed on the close position 21 of location point 9 of jet pipe, oxygen is introduced jet pipe 3.Clearly, other structure also is possible.

The reaction of carbon and oxygen is exothermic reaction, it discharges sizable heat, these heats help temperature maintenance with the material fluid at a suitable high temperature range, the carrying out of impelling pyrolytic process, prevent free ions and simple compound again chemical combination form undesirable compound.

In a kind of possible structure, pipe 6 can comprise one deck graphite lining, and in this case, 21 amounts that enter are very important to control oxygen in the position, and the oxygen in the pipe 6 is remained under the not enough state.As an embodiment, the ratio of oxygen and carbon remains below stoichiometry 30% quantitatively.If do not keep this environment, some oxygen will react with the carbon on the pipe lining, and it will react away lining so.

Oxygen gas also will reduce the combination that can form the dissociated ion of undesirable oxygenatedchemicals.

The material fluid 5 that flows out pyrolysis apparatus 2 outlets 15 in the cooling zone 22 by chilling.In structure as shown in the figure, so material and/or enter subsequently in the environment as mentioned below is attracted on the special carrier at this remaining toxic compounds.As a kind of embodiment, carrier mass can be the nonreactive carbon granule in the material fluid 5.

The concentration of carbon granule for example can be 1% weight percent concentration from export the 15 material fluids 5 that flow out, and is perhaps bigger, and this concentration of carbon may cause the obstruction or the obstruction of some parts of the treating apparatus of pyrolysis apparatus 2 back.Therefore, in some cases, need to introduce an oxygen fluid 23 in addition again, make some carbon granule change into the carbon compound of gaseous state, further reduce the content of carbon thus.Best, the content that enters carbon in the material fluid of cooling zone 22 is 0.5% weight concentration.

In addition, the introducing of oxidation fluid 23 also has the another one effect, that is, the heat that is produced by the reaction of oxygen and carbon can help temperature maintenance with material fluid 5 at a suitable high temperature range, before carrying out chilling.Aspect temperature, the temperature of wishing material fluid 5 had 1500 ℃ at least before chilling, and preferably its temperature is in 1800 ℃～2000 ℃ scope.

As mentioned above, high temperature can press down free ions again chemical combination form poisonous compound, as bioxin, usually, also need the temperature of material fluid 5 was remained on before by chilling in the sufficiently high scope, be reduced into CO to avoid the CO in the fluid 5 ₂

As mentioned above, in all application of the present invention, the introducing of another oxygen fluid 23 is not necessary.

In special tectonic as shown in the figure, cooling zone 22 comprises row's sprayer 24, and it has produced a cooling layer 25 that material fluid 5 must pass.That is to say, fluid 5 is limited in the passage 26 that the layer 25 that is cooled fully fills up in this passage of the position at sprayer 24 places.The feasible chilling to the material fluid of this structure carries out very thoroughly, and material temperature descends very sharp as a result.In embodiment as shown in the figure, passage 26 has prolonged the passage that passes pipe 6.

The chilled material of 22 outflows enters and passes a washer 27 from the cooling zone, and as shown in the figure, the pH value of washer 27 is alkaline, to remove acid compound from the material that obtains.Carbon granule in the material is dispersed in the alkaline detergent solution 28, impels acidic organic compound to be attracted on the carbon granule.Can determine optimal processing parameter by normal experiment,, need to adopt this optimal processing parameter, realize adsorbing to greatest extent poisonous organic compound as the pH value and the temperature of cleaning solution.

In one embodiment, cleaning solution is a sodium hydroxide solution, but the cleaning solution of other types also is available.In addition, in structure as shown in Figure 1, used liquid can be with a kind of liquid in chilling sprayer and washing sprayer 29.Like this, can extract liquid from liquid container 28 with pump 30, supply with

sprayer

24 and 29,31 expressions of Fig. 1 center line are to washer 27 feed fluids, and line 32 expressions are drained used liquid from washer 27.

Can adopt a simple filtering program that carbon granule and cleaning solution are separated, this program represents with square frame 33 that in Fig. 1 filter process can carry out or carry out in bulk continuously.

Adopt a desorption process that the toxic organics that is adsorbed on the carbon granule is separated from carbon granule, this process is represented with square frame 34 in Fig. 1.That is to say that the adsorption process of carrying out in washer 27 is undertaken by reverse, compound is separated and is drawn onto in the water usually, and water is recycled in the technological process by input port 1 as a part of material.

In structure as shown in Figure 2, washer 27 is rectangular configuration, and it is bigger than the pipe that forms cooling zone 22 basically.A plurality of washing sprayers 29 are positioned at the upper area of washer 27, so that directly wash liquid is become tiny water smoke or spraying.The direction of little mist or spraying is preferably downward.

As shown in Figure 5, this device also comprises an explosive ventilation duct 35, and with the volatile admixture of gas that produces in the discharge system, this is an important safety measure that reduces explosion danger.The form of explosive ventilation duct and structure are known, and in embodiment as shown in the figure, ventilation duct 35 is positioned at the place of washer 27 vicinities.

The material that washing is walked from gas in material that keeps with gaseous form and the washer 27 can enter in the atmosphere, by blast pipe 36 as shown in Figure 5.For example, blast pipe 36 can comprise several exhaust sprayers 37, and its effect is in order to remove those residual a small amount of gaseous compounds that alkaline solution is had affinity.In special construction as shown in the figure, by pump 30 to blast pipe sprayer 37 feed fluids.

Specifically pyrolysis apparatus 2, say more roughly that perhaps whole device has formed a very compact device, and this device can use at the scene.For example, this device can be incorporated in the existing processes flow process, making does not have toxic waste to produce at last.This is a main advantage, is breakneck because carry noxious material.

A unique features of described this method is deliberately to be detained granulated carbon in the material flow, and the condition of controlling this process, makes granulated carbon become the carrier mass of poisonous organic compound, and this poisonous organic compound remains in the pyrolysis apparatus of this flow process.That is to say, remained in organic compound in the technological process before quenching process, can be captured effectively by adhering to or being adsorbed on the granulated carbon.Residual organic compound is in the easy to handle mode, perhaps catches as the suitable manner of having considered in the mode of program subsequently in addition, and this depends on the concentration of poisonous organic compound.In the decomposable process of present toxic compounds, the practice that the inhibition carbon of employing generates is disadvantageous.

Material analyzing result from washer is demonstrated, and before washer, the splitting degree of toxic products is on 99.9999% magnitude in the technology, and isolated granulated carbon is for further processing can be made splitting degree be increased to surpass 99.9999%.Method of the present invention is very effective for the poisonous generation of decomposing in the very wide concentration range effectively, and this poisonous generation comprises chlorophenol and dioxin.This method is durable and safe.
