Definitions

  • the invention relates to a method for recovering usable gas from waste by pyrolysis according to the preamble of claim 1.
  • a system for carrying out the method for this is described in the preamble of claim 11.
  • this object is achieved in that at least part of the water bath through which the pyrolysis residues are discharged from the degassing drum amount of liquid withdrawn from the wash water circuit of the gas washing system is introduced.
  • the pyrolysis residue absorbs more than 140 percent by weight of its own weight in liquid with a sufficient residence time.
  • the greater the carbon content of the pyrolysis residue the greater this liquid absorption.
  • a sufficient dwell time for total wetting should be observed, which e.g. can be achieved by a screw conveyor system with a correspondingly slow speed.
  • the garbage entered in the degassing drum is previously removed by sorting out inert substances. This can be done using suitable sorting devices such as, for example, comb roller sorters. It has now also been shown, unexpectedly, that the pyrolysis residue treated in this way obtains an activated carbon structure with chemosorbing properties, which means that it can be used as activated carbon for any application.
  • the amount of wastewater from a pyrolysis gas plant which processes household waste is reduced by more than 50% and generally less than 100 liters of wastewater per ton of household waste disposal.
  • This amount of waste water is usually so polluted that untreated discharge is ecologically undesirable.
  • a significant and cost-effective reduction in pollutant pollution can be achieved if it is provided in a further development according to the invention that the amount of liquid withdrawn from the water circuit of the gas scrubbing system is pretreated in batches by ozone injection in such a way that after the treatment the concentration is treated of cyanide is ⁇ 10 g / m 3 and phenols ⁇ 40 g / m 3 .
  • Such a pyrolysis residue which has a liquid content of approx. 60 percent by weight, is a particularly nutrient-rich carrier substance for anaerobic methane gas generators, which convert the absorbed, biologically convertible groups of substances into useful gas, due to the balanced levels of phenols and cyanides due to the high carbon and ammonium content from gas scrubbing.
  • the ozone-controlled homogenization of the pollutants minimizes the risk of overdoses and thus the destruction of culture.
  • a short ozonization which is generally less than a quarter of a full ozonization time, is sufficient to achieve this homogenization effect.
  • the excess water not bound by the pyrolysis residue which generally corresponds to less than 50% of the portion withdrawn from the water cycle of the gas washing system, is fed to a residual ozonization. This can be done either in parallel with a use in a biogas plant or instead.
  • the COD can be reduced to below 400 mg oxygen per liter, the BOD to approx. 60 mg / m 3 and the proportion of cyanide and phenols to generally below 0.1 g / m 3 .
  • this pyrolysis residue can be used for the energetic supply in lime kilns.
  • it can preferably be pressed into egg briquette-like pellets.
  • its calorific value may correspond approximately to that of lignite, which is sufficient for a smelting process. If the correct mixing ratios are observed, the inert material fractions are calcined or ceramized, which in particular also includes heavy metals.
  • the molar ratio of SiO 2 , Al 2 O 3 , CaO. ZnO, Fe 2 O 3 and / or MgO is at least 6: 1 to the total molar fraction of the metals lead, chromium, manganese, cadmium, berilium, barium, selenium, arsenic, vanadium, antimony, bismuth, strontium and / or zircon.
  • the available useful energy can increase by more than 5% through a reduction in the own electricity requirement for the ozone plant for gas cleaning and through the improved energetic use of the pyrolysis residue.
  • the pyrolysis residue is used in biogas plants, its economic efficiency for the thermal conversion of waste materials can be increased.
  • the residues in the method according to the invention requiring final storage are several times smaller than the residues in a waste incineration plant, which are also highly toxic and must be disposed of as special waste.
  • the waste is conveyed via a conveyor belt 1 into a primary crusher 2 for coarse shredding.
  • a conveyor trough 3 and a conveyor belt 4 with a magnetic separator 5 transport the Garbage in a sorting device 6.
  • the heavier, wet, vegetable fraction is separated and falls into an underlying container or onto a conveyor belt 7.
  • inert substances can also be separated off in order to increase the carbon content of the pyrolysis material.
  • the remaining waste fraction is fed to a thermal screw press 14 via a further conveyor belt 8, a further shredding device 9 and a downstream hydrocyclone 10, in which heavy parts are separated again via a line 11.
  • fluff ie a loose waste form, or pellets, ie waste components compressed into briquettes
  • the waste components crushed in this way pass over a rotary valve 15 or other entry devices, such as, for example, stuffing screws in a degassing drum 16, in which carbonization gas is produced in a known manner at temperatures of 450 to 600 degrees Celsius, which gas is introduced into a high-temperature gas converter 19 via a discharge line 17 and a dust separation device 18.
  • the carbonization gas is worked up or converted over a coal or coke bed.
  • a gas converter of this type is described for example in DE-OS 33 17 977.

Abstract

Selon un procédé de récupération par pyrolyse de gaz réutilisables à partir de déchets, on transforme les déchets concassés au préalable en bourre, granulés ou boulettes, puis on les introduit dans un tambour de dégazage (16), dans lequel un gaz dégagé par une combustion lente est généré et séparé des matières résiduelles. Le gaz ainsi généré est décomposé dans un convertisseur de gaz (19) en gaz de combustion, nettoyé par la suite dans une installation de lavage de gaz (21-24 et 47-51) avec une eau de lavage s'écoulant dans un circuit fermé. Afin de limiter la concentration de matières toxiques dans l'eau de lavage s'écoulant en circuit fermé dans l'installation de lavage de gaz, on en enlève une partie pour la remplacer par de l'eau pure. Les résidus de la pyrolyse à évacuer du tambour de combustion lente sont évacués en passant par un bain-marie (72). Au moins une partie de la quantité d'eau prélevée dans le circuit d'eau de lavage de l'installation de lavage de gaz (21-24) est ajoutée au bain-marie (72).
