Definitions

  • the invention relates to a method and an apparatus for the treatment of solid combustion residues a waste incineration plant.
  • the combustion residues are known from DE 711 606 C. in one, a chute and a purification container with increasing discharge chute To promote detoxification and from there by means of a To push out the push rod.
  • EP-C-0 304 412 discloses combustion residues at least one basic and advantageous then also undergo an acid wash to not just the water-soluble components, but also the heavy metals loosely bound into the slag remove.
  • an acid wash to not just the water-soluble components, but also the heavy metals loosely bound into the slag remove.
  • the equipment provided for this downstream of the detoxifier is a relatively large apparatus Effort necessary, the equipment provided for this downstream of the detoxifier.
  • DE-C-524 207 discloses slag in one Damming the shaft and sprinkling it with water from above.
  • This shaft has an obliquely arranged, water-permeable Wall through which the fire water is drained can.
  • the aim of this invention is to reduce the slag as much as possible pre-dried to be removed from the shaft and onto a conveyor belt bring to dirt by dripping of the extinguishing water during the subsequent removal avoid. The result is that there is only so much water for sprinkling is fed as it is for quenching the slag is required.
  • GB-A-379 508 is a discharge device for Combustion residues are known in which the effluent Multiple wash gases through water bath and shower heads is subjected to, while the solid residues by means of a scraper conveyor from a shaft into a liquid container introduced and deleted there.
  • a Slag washing in a chute in which the Wash liquid trickles down from the top to the to be able to wash all slag in this chute is not provided there.
  • the object of the invention is to minimize the outlay on equipment to avoid and still treat the solid Allow combustion residues to be satisfactory Slag properties with regard to landfill ability and further processing lead to building materials.
  • heavy metals are achieved by that a chemical, preferably acid, e.g. Hydrochloric acid or phosphoric acid is used, whereby by the Accumulation or piling of solid combustion residues, especially beyond the liquid surface, especially good ones Requirements for washing with a chemical, especially acid, as created by the piling up of the Combustion residues have to travel long distances for the washing liquid through these combustion residues and thus large Residence times are available without additional containers or reactors a satisfactory washout of Heavy metals from solid combustion residues guarantee.
  • a chemical preferably acid, e.g. Hydrochloric acid or phosphoric acid
  • That kind of peeling the resulting sludge is particularly special advantageous if starting with washing liquid in countercurrent is worked by the expeller, since in the area of Liquid surface at the bottom of the chute the two Currents meet within the detoxifier so that on the one hand, the one already trickling down in the chute Washing liquid separated components and on the other hand those Components that can be removed from the combustion residues can be removed have accumulated again and by the end of the extension imported washing liquid are rinsed off.
  • Detoxifying water can be used in a further embodiment of the invention either one downstream of the combustion process Emission control device or a washing stage Neutralization of acidic, coming from the combustion process Exhaust gases are supplied.
  • this will be Detoxifying water evaporates in the exhaust gas stream, being acidic on the one hand Exhaust gases can be neutralized and on the other hand around the To expel water content. The dry part the other Filter dusts from the exhaust gas of the incinerator were deposited.
  • the second option is the use of the detoxifying water to neutralize acidic Exhaust gases in wet scrubbers.
  • the applied in the area of the upper end of the fall shaft amount of washing liquid is 0.2 per tonne of combustion residues to 20 m 3, while the fed in countercurrent at the Ausschubende of the ash amount of the washing liquid is 0.2 to 4 m 3 per ton of combustion residues.
  • the device for carrying out the method is marked through a detoxifier, in the area of the upper end of the chute a device for feeding Wash liquid are provided through which the wash liquid can be distributed over the entire cross section of the chute.
  • This Washing liquid can either be circulated Detoxifying water and / or a chemical, preferably one Acid.
  • the device for supplying washing liquid can in advantageously comprise spray nozzles in the side walls of the chute are provided. This configuration allows not just an even sprinkling of the combustion residues with washing liquid but also enables trouble-free Failure of solid combustion residues.
  • the device for supplying washing liquid can also include perforated tubes that cross the chute.
  • the Holes in the tubes act as spray nozzles. Since one with few tubes is a disability within the Falling way of the combustion residues practically not exist.
  • the detoxifier in a further embodiment of the invention one of its liquid level inside the chute or of the detoxifying outlet duct with an airtight one locked sedimentation tank is connected, so a safe and controllable removal of the in the detoxifier due to the Washing process of the detoxifying water including the suspended fine particles without the risk of that false air in the combustion chamber operated with negative pressure can penetrate.
  • FIG. 1 shows a known detoxifier, which has a total of 1 is designated, the one chute 2, an extension chute 3rd and one in the rear area 4 of the detoxifier driven swivel arm 5 includes articulated push rod 6, that falling from a grate, not shown Slag over the rising chute 3 into one Extends chute 7.
  • an inlet 8 fresh water supplied becomes a constant in the detoxifier 1 Liquid level 9 observed, which is set so high that the lower edge 2a of the chute 2 is immersed in the water.
  • This known detoxifier does indeed Slag washing by water, with waste water via a drain 10 is withdrawn at the rear end 4 of the detoxifier 1, however is a large proportion of the fine ingredients that are not under the Immerse the lower edge of the chute together with the Slag discharged into the discharge chute, which is the reason for the unsatisfactory properties of the slag already explained above represents.
  • the light essential components of the detoxifier 1 the same conditions before as in Fig. 1. For this reason, only the Deviations explained.
  • Embodiment is the regulation of the extension of the Push rod 6 set so that the slag 11 in Inlet chute 2 piled up.
  • the washing liquid that Water and / or a chemical, preferably an acid can, is supplied via a ring line 12, the spray nozzles 13 is connected, which in the side walls of the Inlet chute 2 are provided.
  • These spray nozzles 13 allow sprinkling of the piled up slag 11 within the chute 2 over the entire cross section the same.
  • the deduction of the one loaded with washout products Detoxifying water takes place via a discharge line 10, which runs from rear area 4 of the detoxifier 1 goes out.
  • Fig. 3 shows the same structure of the essential parts of the Detoxifies an amendment to the execution form Fig. 2.
  • a washing liquid, the Water or a chemical, especially a base or Phosphate compounds can be via the inlet 8 in Discharge shaft 7 of the deslagger 1 is supplied. That about the Discharge line 10 from the rear room 4 of the detoxifier drawn off detoxifying water loaded with washout products is by means of a pump 14 leading to the spray nozzles 13 Ring line 12 pumped via a line 12 a.
  • FIG Device for performing the method is fresh water or a chemical, preferably a base or a substance from the Group of the phosphates via the inlet 8 into the discharge shaft 7 introduced.
  • a chemical preferably an acid and / or in circulation guided detoxifying water.
  • the latter becomes a sedimentation basin 17 removed, which is sealed airtight and over a Extraction channel 18 is connected to the detoxifier 1, wherein the exhaust duct 18 from an area at the level of Liquid level 9 within the chute 2 or the underlying detoxifier goes out.
