Definitions
- the invention relates to a method of treatment combustion residues of an incinerator, in particular Waste incineration plant where the fuel burned on a grate, and the resulting Combustion residue by appropriate regulation of Combustion be brought to an elevated temperature.
- molten Combustion residues Due to the high temperatures in the treatment of Combustion residues in a smelting stage are molten Combustion residues due to low levels of organic Marked connections. While typical Slags from waste incineration plants still unburned, usually measured as loss on ignition, from 1 to 5% by weight show the loss on ignition of molten combustion residues at below 0.3 wt .-%. In addition, are molten Combustion residues due to small proportions characterized by leachable salts and heavy metals, because these either evaporated or in the case of cooling the Melt forming glass matrix are involved.
- the object of the invention is to provide a method in the combustion process is so influenced and regulated will that a completely sintered slag with the desired Quality without the use of downstream Melting or glazing aggregates is obtained, and in a low expenditure on equipment, the disadvantages of dust development the air termination of the firebox avoided and low consumption of water becomes.
- a "completely sintered slag" becomes a material understood that consists of sintered and / or melted chunks, typically a grain size of at least 2 to 8 mm. These chunks consist of combustion residues of garbage by complete or superficial Melting are agglomerated.
- the sintered or smelted pieces may be due to gas release during sintering or melting quite a porous Have structure.
- the possible porosity of the fully sintered Slag is due to the fact that the temperature the molten slag in the fuel bed is not high is enough to have a sufficiently low viscosity and thus to cause expulsion of gas bubbles, which in the Glass technology is also referred to as Läutern. This is different the completely sintered slag of typical vitrified slags that are in downstream high-temperature process in crucible furnaces lined with refractory material or other melt aggregates.
- the fully sintered slag can also constituents of waste, such as glass or metals, containing of the combustion process largely unaffected the Walk through grate, so in the narrower sense in the fuel bed neither melted nor sintered, but in terms of Burnout and leachable pollutants the desired properties have.
- sintering is equivalent to Hämmerli (garbage and waste 31, Supplement Disposal of slags and other residues, Page 142, 1994) as a special case of melting and freezing.
- Sintering is often used in science Application of this term as “superficial fusion or fusing together of particles. "The chunks of sinter The completely sintered slag can also be completely or partially melted.
- Residual slag will be the slag constituents below not sintered and / or melted are. Residual slag is characterized by a comparison to completely sintered slag smaller grain size as well higher loss on ignition and proportion of leachable pollutants.
- the first way according to the invention is that the Combustion control is conducted so that already in the Brennbett the main combustion zone a sintering and / or Melting of the combustion residues to Slag occurs that the resulting combustion residues deleted altogether in a wet slagger and off be brought out of this, that from the Wet slagger coming wet combustion residues first by a mechanical separation process in two Fractions are split, which is essentially a Coarse fraction and a major fraction containing oversize fraction with withdrawn from the wet slag water washed and thereby separated smaller parts separated and that the wash water with the Washing process recorded finer parts of the Wet slag is fed.
- the invention comprises two main areas, one of which Main area in the combustion control and the second Main area in the mechanical processing of the by the Combustion process obtained combustion residues consists.
- This second main area comprises two process variants, which depend on the composition of the fuel.
- the first main area is for both subsequent process variants in terms of mechanical processing Consistent and is the combustion process on the firing grate so influence that already one Sintering and / or melting process on the grate in the main combustion zone takes place and that each not yet sintered or molten combustion residues be traced back to the second or third pass the desired sintering and / or To experience melting.
- the focus of the inventive concept is therefore the sintering and / or melting process of the combustion residues already in the fuel bed of the main combustion zone, which was not thought possible until now. It is namely for mechanical firing grates extremely harmful, if liquid slag between the individual grate bars or Other movable parts of the Feuerungsrostes arrives. Out For this reason one has a melting of the slag on the Avoided rust and made sure that in the fuel bed the Melting temperature of the slag is not reached.
- the sintering and / or Melting process in the upper part of the fuel bed instead, because from the top the largest heat effect by the Radiation of the flame body takes place and from below by supplying relatively cold primary combustion air the Temperature of the directly on the Feuerungsrost lying Material can be kept lower than on the top of the fuel bed. Because with such a combustion control not the entire incipient combustion residues in a completely sintered slag with the desired Quality can be converted, those are Combustion residue, which does not yet have the character of completely sintered slag, the combustion process fed again.
- the crushing of the main fraction has the consequence that in the subsequent washing process those in the combustion residues in the larger ones Parts of trapped pollutants washed out and thus can be separated from the main recyclable fraction, whereby despite stronger load of these combustion residues with pollutants a large proportion of combustion residues be recovered as recyclable slag can, without later with the washing out of pollutants must be expected on a larger scale.
- an oxygen enrichment of the primary combustion air to about 25 vol .-% to 40 vol .-% is made.
- Another advantageous measure is that a preheating the primary air temperature to values of approx. 100 ° C to 400 ° C is performed. These measures may vary depending on Conditions are used separately or combined. Preferably, depending on the nature of the Burning the fuel bed temperature in the main combustion zone set to 1,000 ° C to 1,400 ° C.
- the resulting in the mechanical separation ultrafine fraction and fine fraction are in a further embodiment of the invention fed to the combustion process. These fractions are again subjected to a combustion process, thus reducing the possibility of melting and sintering consists of these fractions.
- the level can be maintained in the wet slagger, because of the discharged amount of combustion residues always water is mitabdress, reducing the amount of water in the wet slag decreases and filled up anyway would have to be. Since the water coming from the final rinse has only low calcium and sulphate contents not the risk of clogging pipes or nozzles.
- the main fraction still large proportions of an oversize fraction which usually has a high scrap content possesses, in a further embodiment of the invention the coarse fraction another mechanical separation process be subjected.
- the ultrafine fraction is about one grain size from 0 to 2mm
- the coarse fraction with a grain size of 8 to 32mm and the oversize fraction are at a grain size over 32mm
- these values are only for better understanding of a Groborient ist provided, of course each fraction a certain proportion of the underlying may contain finer fraction, as long as the finer fraction is of secondary importance.
- the Fine fraction coming directly from the purifier and having a grain size of about 2-8 mm, those Proportion of combustion residues, preferably the Combustion process is fed back.
- the second Process variant is, however, by the crushing process obtained a grain fraction, this fine fraction in the core distribution, but in terms of quality has a higher standard for reuse, so that this fine fraction called quality fine fraction can be.
- a separation limit of 32mm is maintained, that is, if so the oversize fraction is deposited, so it is recommended to use a second mechanical Provide separation, which then for example at 8mm, with all parts that are smaller than 8mm, again be supplied to the combustion process.
- the main fraction which is an oversize fraction and coarse fraction this way, not only from the big ones Scrap parts, but also from all other metal parts be released, which supplied to a separate recycling become.
- the oversize fraction another crushing process to submit, as parts, for example larger than 32mm are little for this purpose are suitable.
- the separated from the main fraction coarse fraction with the crushed combustion residues from the oversize crushing mixed to a first mixed fraction become. It may turn out to be appropriate that the mixed fraction a mechanical separation process is subjected, as in the crushing process, such Grain sizes incurred, which is undesirable for further utilization are and, for example, the combustion process should be returned.
- the second Mixed fraction washed with water from the wet slagger and the ultrafine fraction is separated, it is ensured that the proportions below 2mm grain size, often particularly heavily polluted, of the recoverable Shares are separated.
- This laundry can conveniently on a sieve with a sieve passage 8mm or smaller.
- the slag water in connection with these fines and fine steels is the Wet slag fed again.
- the washed slag is deducted and for recovery, for example in Road construction, used.
- the deposited during the screening Fine fraction with a mass of about 100kg usually becomes again given to the grate firing, to a more extensive To achieve sintering. But it is also possible this Contribute to other treatment methods.
- 40 liters Inlet water or fresh water are supplied to the To compensate for water loss in the wet slagger by it occurs that the combustion residues in the discharge Of course, liquid from the wet slagger carry.
- a final rinse with fresh water which with a quantity of 80 liters the 200kg of the main fraction added in order to free them from adhering components, from the wet treatment by the water from the Wet slag originate.
- 40 liters of this rinse liquid be used for waste gas purification or other disposal, diverted, while another 40 liters the wet slagger be supplied to compensate for the loss of water. The way cleaned slag can be recycled become.
- FIG. 3 shows a variant of the method according to the invention.
- this modified process will be 1000kg of garbage an ash content of 220kg fed to a grate firing.
- This wet slag becomes combustion residues deducted on the order of 336kg.
- the weight gain is due to fine particles that over the Slag water recycling fed to the wet slagger become.
- the wet slagger will be 40 liters of water as Balancing supplied for the discharged water.
- the 336kg Slag or incineration residues reach a sieve with a separation grain size of 32mm.
- the oversize fraction with a grain size of> 32mm is first a metal deposit fed.
- the accumulating slag enters a crusher to slag of the order of 8mm to obtain.
- This slag so obtained will be on another Sieve brought with a separation grain diameter of 8mm.
- this mechanical separation will be 100kg slag or Combustion residues with a grain diameter of ⁇ 8mm deducted and preferably the grate firing again fed.
- the remaining coarse fraction becomes a metal deposit fed.
- the obtained metal parts and the metal parts of the metal deposit from that described above Process step are merged and a wet treatment fed to adhering slag parts rinse. This will be 20kg of ferrous and non-ferrous metals obtained, which are recycled.
- the scrapped Slag or coarse fraction with a grain size of 8 to 32mm has a weight of 215kg.
- 60kg of this are fed to a crusher and to a grain size> 2mm crushed.
- the crushed Mass fed to the main stream of 155kg and a wet treatment on a sieve with 2mm cut size.
- the washing water is used in an amount of 1000 liters taken from the wet slagger.
- 155kg slag with a grain size of 8 to 32mm and a finer proportion of 45kg with a grain diameter from 2 to 8mm in front. These two factions will be recycled, while fines, the one Diameter of less than 2mm, the wet slagger be fed again.
- the flowchart of Figure 4 shows the basic variant, accordingly FIG. 1, in conjunction with the addition of a precipitant for soluble heavy metals.
- This precipitant is added to the wet slag to reduce the lead content of the Purifier water of usually 2mg / l to 0,05mg / l too reduce. This reduces the cargo of dissolved lead to 1mg, with about 20l adhering slag water 200kg of wet-treated slag is present.
