Definitions
- the invention relates to the field of thermal waste treatment. she relates to a process for the treatment of slag and / or ash from the thermal treatment of garbage.
- EP 0 372 039 B1 describes a process for treating the slag from waste incineration plants known in which the slag dry from the incinerator is carried out, a rough cleaning (removing unburned Coarse goods and magnetic parts) is subjected, and then the coarse cleaned slag is separated into at least two fractions and one of them all particles smaller than 2 mm are assigned. This procedure is based on the knowledge that the fine fraction is the largest part of the original contains pollutants contained in the slag. The fine fraction will a special treatment, while the coarse fraction z. B. as a building material suitable is.
- the volatilization reactions (Reaction of the solid metal oxides with the added carbon to gaseous metals and carbon monoxide) run in the solid layer of the rotary kiln, which is constantly circulated. In the above The volatilization products become gas spaces with an oxidizing atmosphere then reoxidized. These gaseous phase oxidation products are very finely divided so that it is carried away by the flue gas and transported out of the oven and finally separated after the flue gases have cooled down. The low-metal slag is discharged from the furnace, cooled and then opened Dumped.
- the invention tries the above. Disadvantages with the known preparation of To avoid garbage slag. It is based on the task of being effective and inexpensive Process for the treatment of slag and / or ash from the provide thermal treatment of garbage, which with a robust and simple technology can be realized and with no additional classification and Crushing stages create an inert slag depleted of pollutants.
- this is the case with a method according to the preamble of the patent claim 1 achieved in that the waste in a first process step is pyrolyzed, gasified or partially incinerated, with slag containing heavy metals and / or ash with a comparatively high carbon content is said slag and / or ash in a second process step in a rotary kiln to a temperature below the melting temperature of the Slag and / or ash is heated up that the slag and / or ash before their discharge from the rotary kiln remains in the rotary kiln for a sufficiently long time, so that the heavy metals contained in it by reduction on the own slag Carbon is converted into its metallic form and the volatile Heavy metals such as zinc, lead, arsenic and cadmium are converted into the gas phase and are discharged from the rotary kiln with the flue gas, and that a heavy metal-depleted slag is discharged from the rotary kiln becomes.
- the advantages of the invention are that the slag in one of pollutants depleted state arises.
- the heavy metal contents are clear below the legally prescribed maximum values for inert material landfills of the Swiss Waste Technical Ordinance (TVA) dated 10.12.1990.
- Highly harmful Hydrocarbon compounds, such as. B. dioxins are below the detection limit. Therefore, the slag prepared in this way can be easily Ferrous and non-ferrous metal separation, for example as a building material in the Road construction used or otherwise used. An expensive one Landfill is unnecessary.
- the preparation means in a rotary kiln the advantageous use of robust technology. Time consuming classification and Crushing stages for processing the slag are not necessary.
- the slag introduced into the rotary kiln and / or ash contains at least 10% carbon, because then one is sufficient large amount of reducing agent for the reduction and volatilization of heavy metals is available.
- the slag is dry from the rotary kiln is carried out and separated into at least two fractions, the first Fraction with a particle size larger than approx. 32 mm in a first sieving stage is separated as a screen overflow, and the screen diarrhea of a second classification stage for the purpose of separating the fine fraction 0 ... 2 mm, whereby at least part of the fine fraction 0 ... 2 mm from the slag processing on the Air inlet side is returned to the rotary kiln and burned there. Thereby the ash burnout in the rotary kiln is increased and the pollutant content the slag reduced even more.
- Rubbish 1 preferably household waste, is disposed of in a Feeding device, not shown, fed to a waste incinerator 2 and burned there on a grate 3 using the grate firing process.
- the Incinerator 2 is a boiler 4 and a dedusting system 5 on the gas side, e.g. B. an electrostatic filter.
- the incinerator is on the slag side 2 is followed by a rotary kiln 6.
- the waste 1 is burned in the incinerator 2 with the supply of primary air 7, that a slag 8 is produced which has a loss on ignition of at least 10 % having.
- the loss on ignition is a measure of the unburned portion in the Slag 8 and thus an indirect measure of the carbon content. So this comparatively high loss on ignition and thus high carbon content is achieved, Incomplete combustion must take place in furnace 2. So far she had Incineration using the grate combustion process is always the goal, if possible the waste 1 to burn completely, i.e. a slag with the lowest possible loss on ignition and thus to generate low carbon content.
- the heavy metal and carbonaceous slag 8 from the incinerator 2 falls directly from the grate 3 into the rotary kiln 6 without intermediate cooling Discharged dry without water humidification.
- the slag 8 has after Rust a temperature of approx. 400 ° C.
- Rust a temperature of approx. 400 ° C.
- it is together with the filter dust 10 from the dedusting system 5 by means of an oil burner 16 heated to a temperature of 900 ° C. This temperature is below the Melting temperature of the slag / ash 8, 10, but above the volatilization temperature the heavy metals contained therein.
- the rotary kiln 6 is so large that the Residence time of slag / ash 8, 10 in rotary kiln 6 after heating approx. Is 1.5 hours. For this reason, the rotary tube has a length of 8 m and an inner diameter of 2.5 m.
- the volatilization reactions (reaction of the heavy metal oxides with that in the Slag containing carbon to gaseous metals and carbon monoxide) run in the solid layer of the rotary kiln 6, which circulates continuously becomes. In the gas space above with an oxidizing atmosphere, the Volatilization products then reoxidized. These reaction products from the gaseous phase are very fine, so that they are entrained by the flue gas 9 become.
- the flue gas 9 is then cooled in a steam boiler 13 and filtered in a dust filter 14. This filter dust enriched with heavy metals can then be further treated with the aim of being in them recover heavy metals contained.
- the heavy metal depleted Slag 15 is discharged from the rotary kiln 6, cooled and can after scrapping and non-ferrous metal separation using a magnetic separator or non-metal separator (not shown in Fig. 1) easily used (e.g. as Building materials in road construction) or on a heap.
- a magnetic separator or non-metal separator not shown in Fig. 1
- the following table shows for the exemplary embodiment the contents of heavy metals and dioxin for the starting materials and the end product of the rotary kiln 6 compared to the maximum values for inert landfill quality according to TVA: Fly ash Slag from rust Slag after rotary kiln TVA, inert landfill quality Loss on ignition % 5 > 10.0 ⁇ 1 Pb ppm 9000 2500.0 400 500 Zn ppm 16000 4000.0 500 1000 CD ppm 2400 13.0 nn 10th Dioxin concentration ng TE / kg 1600 11.5 nn
- Fig. 2 shows a diagram to clarify what has just been said on the one hand the zinc or lead concentrations in the slag depending on their residence time in the rotary kiln and on the other hand the bed temperatures depending represents from that time.
- the course of the curves shows that the slag 8 should stay at least one hour in the rotary kiln 6, because only then a sufficiently large depletion of heavy metals takes place.
- the slag prepared in this way can be used, for example, as a building material in road construction used or otherwise used. An expensive landfill is unnecessary yourself.
- processing in a rotary kiln is the most advantageous Use of robust technology. Time-consuming classification and shredding stages for the treatment of the slag are not necessary.
- filter dust 10 can be applied by using only the carbonaceous slag 8 the grate combustion is fed to the rotary kiln 6.
- waste incineration and slag processing take place in one and the same unit.
- Untreated domestic waste 1 with a calorific value of approximately 10,000 kJ / kg is introduced into a rotary kiln 6 with a length of 12 m and an inner diameter of 4 m.
- the amount of waste is 10,000 kg / h.
- the garbage 1 is now partially burned by the addition of air, the combustion air 7 having been preheated to a temperature of approximately 400 ° C.
- the amount of combustion air 7 is such that, on the one hand, a temperature of 1000 ° C.
- the amount of combustion air is 7 12,000 Nm 3 / h.
- the residence time of the waste 1 in the rotary kiln 6 is approximately 2 hours. This time is sufficient on the one hand to burn garbage 1 (incomplete) and on the other hand to deplete the resulting slag / ash from heavy metals by volatilizing them.
- the slag 15 is then discharged from the rotary kiln 6, cooled and, as already described in the first exemplary embodiment, can continue to be used after separation of iron and non-ferrous metal.
- the flue gas 9 from the rotary kiln 6 is then completely burned out by adding secondary air 11 in the afterburning chamber 12, cooled in the boiler 4 (flue gas amount at the end of the boiler approx. 53 600 Nm 3 / h) and cleaned in a flue gas cleaning system 5.
- the slag 15 dry from the rotary kiln 6th is carried out and separated into at least two fractions, the first Fraction with a particle size of approx. 32 mm in a first sieving stage is separated as a screen overflow, and the screen diarrhea of a second classification stage for the purpose of separating the fine fraction 0 ... 2 mm, and at least part of the fine fraction 0 ... 2 mm from the slag processing on the Air inlet side is returned to the rotary kiln 6 and burned there. Thereby the ash burnout in the rotary kiln 6 is increased and the pollutant content the slag further reduced.
