Definitions

  • the invention relates to a method for the preparation of samples from metal-containing ashes from incineration plants, in which a defined amount of the slag to be examined is dried with a defined grain size to a defined residual water content, and the dried sample amount is divided into a predominantly ferrous first part and a predominantly inert one Material and metals containing second part is separated.
  • the invention relates to the preparation of samples from at least aluminum and / or silicon-containing ash or slag from household waste incineration plants (HMVA) or other slag or combustion residues, ashes, waste or granules that have to be analyzed.
  • HMVA household waste incineration plants
  • ashes are used predominantly, without this being intended to be associated with a restriction.
  • Hazardous properties or ingredients according to the designation HP1 to HP15 can be found in these regulations, which specify the use or disposal of the slag, ash and waste.
  • the properties or ingredients according to the designation HP14 are relevant, through which limit values for certain toxic metals and metal compounds are specified.
  • the metals listed above are generally non-toxic in their elemental, native form. Rather, it is their compounds, e.g. copper sulfate, zinc chloride or silver nitrate, which are classified as harmful. However, if these metals are present in solid form in the ash or slag, they are harmless. The ashes could then easily be dumped or reused.
  • a sample Before a sample is subjected to a substance analysis, for example according to the XRF method (X-ray fluorescence analysis) or the ICP-OES method (Inductively Coupled Plasma - Optical Emission Spectrometry, optical emission spectrometry using inductively coupled plasmas), the sample must be processed .
  • a sample is obtained from the ash to be examined, for example in accordance with the LAGA PN98 regulation.
  • a sample amount for example with a grain size of 2 mm to 6 mm, is taken from the sample. This grain size corresponds to about 35% by weight of the resulting HMVA ash.
  • This amount of sample is dried to a dry matter content of> 98% by weight.
  • the dried sample is comminuted in a disk mill to a grain size ⁇ 100 ⁇ m, then digested in aqua regia and then analyzed using one of the above-mentioned methods.
  • the entire sample material is comminuted, including the native metals it contains.
  • these are only harmful to the environment in powder form, but not in their original, solid form. Nonetheless, these solid metals powdered in this way are recorded in the analysis and count as ingredients, although according to the regulation they do not belong to the hazardous ingredients according to HP14.
  • the measured proportion of the metal in question is therefore usually significantly higher than the proportion of the same metal that is present in the ash in compounds that are hazardous to health or ecotoxic.
  • the invention is based on the object of developing a method for processing slag, waste, granules or ashes of the type described at the outset in such a way that a more precise measurement of the relevant ingredients is possible.
  • At least a subset of the second part, which contains predominantly inert material and metals, at least partially in at least one comminution step to form a sample powder with a defined grain size of less than 500 ⁇ m and in particular less than 100pm is comminuted that at least a fraction of the sample powder is subjected to a thermal extraction at a temperature greater than 700 ° C and in particular less than or equal to 1,100 ° C, at which at least some of the pulverized elemental metals burns, and that the combustion residue is made available for analysis.
  • the thermal extraction is carried out at a temperature between 950 ° C and 1,100 ° C.
  • the previous first separation of the iron-containing constituents also removes the abrasive iron oxides from the sample, so that the second part of the sample can be comminuted more easily.
  • This part mainly consists of an inert material and metals, including the metals Pb, Cu, Se, Sn, Zn and Ag and their compounds relevant here.
  • Metals should be understood here to mean the entirety of metals and metal compounds.
  • the metals of the non-ferrous fraction deposited in the magnetic separator may still contain iron constituents that could not be separated.
  • the solid metals that are not relevant for the question of storage or reuse of the ash can be easily removed. These metals are present in the ashes in a non-harmful, solid "lumpy" form and are first ground to a powder in the course of processing. This makes the listed pure metals flammable at the selected temperature. As soon as a pure metal is burning, the resulting metal vapor can be withdrawn from the sample part using simple and known means.
  • the ash generally also contains aluminum and / or silicon (amorphous), which are also ground to a powder.
  • Aluminum and / or silicon are always contained in the ashes of household waste incineration plants.
  • aluminum powder has the property of self-igniting at around 400 ° C, with silicon the ignition temperature is 490 ° C. This means that the ignition sources required for the relevant metals are inherently available for thermal extraction. Heating to over 700 ° C initially ignites the aluminum together with the silicon, which causes the other metals, which are now in powder form and, as the temperature rises, to ignite themselves or due to the ignition source formed by the self-ignition of aluminum or silicon.
  • the thermal extraction is carried out at a negative pressure.
  • the resulting combustion gases are reliably discharged.
  • the residue is then fed to an analysis, for example an ICP-OES analysis method.
  • the residue is ground in a known and specified manner and digested with aqua regia (mixture of 3 parts 65% nitric acid, HNO 3 , and 1 part 37% hydrochloric acid, HCl).
  • aqua regia mixture of 3 parts 65% nitric acid, HNO 3 , and 1 part 37% hydrochloric acid, HCl.
  • the determined proportions of the metals in question reflect the proportion of dangerous metal compounds from Pb, Cu, Se, Sn, Zn and Ag reflected.
  • the mass content of the relevant metal compounds can be calculated from this.
  • the iron oxides that are not relevant for the classification as waste according to HP14, but are abrasive, are removed beforehand.
  • the mills for comminuting the samples therefore have a longer service life.
  • Jaw crushers, ball mills or disk mills can be used for size reduction.
  • the residue from the thermal extraction can be ground to the desired grain size of ⁇ 100 ⁇ m, for example with a mortar.
  • the ferrous first part can be reliably separated from the sample with a magnetic separator. This separation process is known and therefore does not need any further explanation.
  • a further fraction is taken from the sample powder, which is made available immediately for an analysis. This allows the result of the first analysis to be checked and the content of solid metals to be determined by simply forming the difference. This knowledge can be advantageous for the further processing of the ash, for example.
  • the first part of the dried sample quantity in at least one comminution step to a test powder a defined grain size of less than 500 microns and in particular less than 100 microns, and that at least a fraction of the test powder is subjected to a thermal extraction at a temperature greater than 700 ° C and in particular less than or equal to 1,100 ° C, in which at least a portion of the powdered elemental metals burns and that the combustion residue is made available for analysis.
  • the thermal extraction can take place at a temperature between 950 ° C and 1,100 ° C.
  • the proportions of the relevant metal compounds are also recorded, which adhere to the magnetic iron, for example through sintering processes, and thus get into the first separated part. The result will be more accurate.
  • the second part of the dried sample amount containing predominantly inert material and metals is separated into a first part, which consists at least predominantly of inert material and metals, and a second part, which at least predominantly consists of consists of a non-ferrous metal mixture and is subtracted for an analysis, and that the first portion is used for the production of the sample powder.
  • a large part of the solid metals can be removed from the sample powder to be formed and, for example, weighed out.
  • the non-ferrous metals can be separated out in a known manner using an eddy current separator.
  • the first component is comminuted in a comminution step and separated in a first separation step into a first component, which contains predominantly inert material and metals and forms the sample powder, and a predominantly iron-containing second component, which is provided for an analysis.
  • the ferrous component can also be separated off here by a magnetic separator.
  • the first component can be separated in a second separation step into a material forming the sample powder and a mixture containing predominantly non-ferrous metals, which is provided for an analysis.
  • the material forming the sample powder should be understood here to mean that part of the material from which the Sample powder is obtained in the desired fineness with a grain size of ⁇ 100 ⁇ m.
  • At least a subset of the predominantly iron-containing first part of the dried sample is comminuted in at least one comminution step and separated in a first separating step into a test powder containing predominantly inert material and metals and a test powder with a defined particle size of less than 500 ⁇ m and In particular, the first component forming less than 100 ⁇ m and a predominantly iron-containing second component which is provided for an analysis.
  • the predominantly inert and metal-containing first component is separated in a second separation step into a material forming the test powder and a mixture predominantly containing non-ferrous metals, which is provided for an analysis.
  • the analyzes of the predominantly iron-containing first part of the sample and the second part of the sample, which predominantly contains inert material and metals, can therefore proceed largely in parallel. Due to the hardness of the constituents of this part of the sample, ball mills can be used whose grinding media have a weight of around 1.0 kg to 2.0 kg. This means that the hard iron oxides can also be reliably broken up and ground.
  • the comminuted material has a maximum grain size which corresponds at most to half the maximum grain size of the material before the comminution step. It is useful if the comminution step and the first separation step as well as the second separation step with the sample powder or test powder-forming material are repeated until the grain size of the material corresponds to the grain size of the sample powder or test powder. Starting from a sample with a grain size of 2 mm to 6 mm, three comminution steps, for example with a jaw crusher, are sufficient to obtain a powder with a grain size of ⁇ 750 ⁇ m.
  • This powder can then be ground to a sample powder or test powder with a small ball mill to a grain size ⁇ 100 ⁇ m using the ICP-OEC method before the final analysis.
  • This ball mill can, for example, have grinding media with a weight of about 50 g.
  • the amount of sample is constantly reduced. It must therefore be ensured that the original sample volume is sufficiently large. It has been shown that if the sample is crushed three or four times to produce the sample powder or test powder, an initial quantity of around 250 g is required in order to have around 200 mg available for the final analysis. It can be sufficient if only the sample powder is produced in several stages.
  • the test powder for the predominantly iron-containing first part of the sample can, for example, be comminuted in one step, since it contains only a small part of the relevant metals to be detected.
  • an eluate is obtained from a sample quantity of the sample to be examined, with which the water-soluble ingredients of the ecotoxic metal compounds, such as copper (II) sulfate and zinc chloride, and their proportions in the sample are determined can be.
  • the ecotoxic metal compounds such as copper (II) sulfate and zinc chloride
  • a sample 11 is first taken from the ash 12, slag or waste or the like to be examined.
  • the sample is classified in a known manner and, for example, fraction 13 with a particle size of 2.0 mm to 6.0 mm is dried in drying step 14 until the dry matter content is 98% by weight.
  • the released water 15 is drawn off. Sampling can be carried out in accordance with the LAGA PN 98 regulation and is therefore known.
  • This fraction with granules with a grain size of 2.0 mm to 6.0 mm corresponds to about 35% by weight of the ash that is usually produced in a household waste incineration plant (HMVA).
  • HMVA household waste incineration plant
  • the sample is separated in a separating device 16 into a first part 17, which predominantly contains iron-containing granules, and a second part 18, which is composed predominantly of metals and inert material.
  • the separating device 16 can comprise a magnetic separator, for example. This second part 18 is used to obtain a sample powder.
  • This comminution device can produce a powder 20 with a grain size of ⁇ 500 ⁇ m, so that a fine grinding 21 of the powder 20 to form the sample powder 22 with a grain size of ⁇ 100 ⁇ m takes place in a further comminution step that may be required.
  • This type of sample powder production is shown in dashed lines in the drawing.
  • the second part 18 is separated in a further separation process 23 into a first part 24, which predominantly contains inert material and metals, and a second part 25, which predominantly comprises non-ferrous metals.
  • the known fluidized bed extraction can be used as the separation method 23, the parameters of which are adapted to the grain size and with which the non-ferrous metals can be separated off effectively.
  • the second portion can be fed to a substance analysis 26, for example an X-ray fluorescence analysis, in order to determine the ingredients. This analysis method is known and therefore does not need any further explanation.
  • the first portion 24 is taken to obtain the sample powder 20, 22.
  • the procedure is such that at least a partial amount of the first portion 24 is further comminuted, for example in a jaw crusher 27. It can be provided that the maximum grain size of the comminuted material corresponds at most to half the grain size of the supplied material.
  • This comminuted material is divided again in a first separation step 28, for example in a magnetic separator, into a first component 29, which predominantly comprises metals and inert material in a finer grain size, and into a second component 30 which is predominantly ferrous.
  • the second component 30 can be analyzed in a known manner using conventional methods, for example X-ray fluorescence analysis 31.
  • the first component 29 is separated in a second separation step 32 into a material 33 which forms the sample powder, which predominantly contains metals and inert material, and a material 34 which predominantly contains non-ferrous metals.
  • the known fluidized bed extraction can be used as the separation method in the second separation step 32 come, the parameters of which are adapted to the grain size and with which the non-ferrous metals can be separated well.
  • the non-ferrous metals 34 can be analyzed in a known manner using conventional methods, for example X-ray fluorescence analysis 35.
  • Steps 27 to 35 can be repeated until the grain size of the material 33 forming the sample powder 20 has the desired fineness of ⁇ 500 ⁇ m.
  • the material 33 is ground again in a grinding step 27.
  • an initial size of the granulate 24 of 2.0 mm to 6.0 mm, three passes are sufficient to obtain a powder 20 with a grain size ⁇ 750 ⁇ m if the grain size is reduced by 50% in each comminution step 27.
  • the sample powder 20 obtained in this way is brought to the desired grain size ⁇ 100 ⁇ m in a fine grinding 21 so that the analysis described below can be carried out.
  • the fine grinding can be done by a ball mill, the grinding media of which weigh about 50 g.
  • a first fraction is obtained from the sample powder 22 with a grain size ⁇ 100 ⁇ m obtained at the end of the work-up taken and fed to a thermal extraction 36.
  • the thermal extraction is carried out at a temperature greater than 700 ° and below 1,100 ° C.
  • the contained pure and powdered metals burn and in particular also the metals lead (Pb), copper (Cu), selenium (Se), tin (Sn), zinc (Zn) and relevant for the determination of the ecotoxic properties of the ash 12 to be examined Silver (Ag).
  • the combustion is ignited by the fact that the aluminum (Al) still contained in the ash 12 and also after processing ignites at around 400 ° C. and the silicon it contains self-ignites at around 490 ° C. In principle, however, an external ignition source can also be used. This means that the powdered metals mentioned above can self-ignite and burn off.
  • the thermal extraction 36 is preferably carried out at a low pressure so that the metal vapors 37 can be safely drawn off.
  • the residue from the thermal extraction 36 only contains the toxic and water-soluble metal compounds that are important according to the waste framework directive and the ingredients according to HP14.
  • the residue is comminuted for the analysis in a grinding process step 38, for example by using a mortar.

  • the ICP-OEC method can be used with appropriate preparatory steps to determine the total metal content. From this it is possible to obtain information about the content of pure metals in solid form in the ashes 12.
  • an iron-containing first part 17 was first separated from the dried sample. This part must also be examined to ensure that the analysis is complete. It is provided that the first part 17 of the sample is comminuted to a grain size ⁇ 500 ⁇ m in a comminution step 43 for the production of a test powder. In the part 17, however, particularly hard and abrasive iron oxides are contained, which make the comminution more difficult. Ball mills with grinding media with a weight of 1.0 kg to 2.0 kg can therefore be used here, so that the hard iron oxide components are also reliably ground.
  • the material comminuted in this way is separated in a first separation step 44, for example with a magnetic separator, into a first component 45, which is composed predominantly of metals and inert material, and a second component 46, which is predominantly ferrous.
