Definitions

  • the invention relates to a method for the treatment of the waste gases which still occur in a waste incineration plant and which still contain organic pollutant compounds.
  • the exhaust gases generated in these systems are similar to the flue gases from fossil fuels from industrial boiler systems, such as. B. coal-fired power plants, dust removal, desulfurization and mostly also subjected to denitrification.
  • the object of the invention is to significantly reduce the technical and thus also the economic outlay for the separation, in particular of toxic hydrocarbon compounds, from the exhaust gases of waste incineration plants.
  • This object is achieved according to the invention in a method of the type mentioned in that the exhaust gases are mixed with hot flue gases from the fossil furnace of one or more industrial boiler systems without prior separation of pollutants and are heated to a temperature> 1200 ° C.
  • the mixed waste gases from the waste incineration plant can now be subjected to the usual pollutant separation (dedusting, desulphurization, denitrification) together with the flue gas from the fossil industrial boiler plant and then discharged into the atmosphere.
  • pollutant separation dedusting, desulphurization, denitrification
  • the heat content can now also be treated by untreated, i.e. H. Use unprepared waste directly in a cement plant.
  • the waste gas produced in the waste incineration plant is expediently mixed directly with the combustion air required for the fossil combustion of the cement plant. This ensures homogeneous mixing of exhaust gas and flue gas directly behind the burner.
  • the exhaust gas can also be introduced directly into the cement kiln at a corresponding point.
  • the hot cooling air of the clinker cooler as combustion air for the waste incineration plant. Due to the high temperature of the clinker cooler exhaust air of approx. 800 ° C, optimal firing conditions are created in the waste incineration plant. If the waste incineration plant under reducing conditions, i.e. H. as a waste gasification plant, at least some of the heat required for gasification can also be injected from the hot flue gas of the cement kiln. In this case, the waste gas from the waste incineration plant still contains chemically bound heat, which is released by combustion in the cement kiln.
  • the residues resulting from waste incineration or gasification can be carried out in the usual manner, e.g. B. for road and path construction or, in processed form, for the cement process itself as additives.
  • the hot exhaust gas from the waste incineration plant can expediently also be mixed with the even hotter flue gas from a coal-fired power plant.
  • the temperature level of the flue gases produced is sufficient to achieve the required minimum temperature of 1200 ° C after mixing with the waste gas from the waste incineration plant to destroy toxic ones Hydrocarbon compounds such as B. dioxins and furans.
  • the waste gas from the waste incineration plant is expediently introduced into the lower region of the boiler of the coal-fired power plant, as a result of which particularly long dwell times and thus also heating times of the waste gas in the coal boiler are achieved.
  • coal-fired power plants in particular, to which a waste incineration plant, so to speak, as a satellite plant, is subsequently connected, it can also make sense to mix the waste gases from the waste incineration plant directly into the combustion air for the coal burner's coal burners and to enter them into the power plant boiler.
  • waste gases of the waste incineration plant into the boiler of the coal-fired power plant are discharges into the coal drop shaft of the coal mill, into the suction shaft of the smoke gas used for grinding and drying, i.e. in front of the coal mill, as well as in the presence of mill air blowers in the air duct in front of or behind the Mill air duct.
  • the waste incineration plant can only be set up at a greater distance from the power plant boiler, it can also be expedient for the hot flue gases of the exhaust gases, for example in indirect or direct heat exchange with combustion air for the coal boiler , so far to cool down that a complex lining of the exhaust gas connection line between the waste incineration plant and the power plant boiler can be omitted.
  • the waste intended for the waste incineration plant beforehand into a coarse fraction with a higher calorific value, which is then fed to the incineration plant, and into a fine, low calorific value fraction which is first subjected to a rotting process and then burned together with the fossil fuel in an industrial boiler, preferably a coal-fired power plant boiler.
  • the high calorific value fraction is burned in a grate furnace after sorting out the largest contaminants and passing through a magnetic separation either directly or after transport with press containers. Transport in baled bales is also possible, although this requires a crushing stage.
  • the flue gas from the grate furnace is fed into the coal-fired large boiler and passes through the boiler together with the flue gas from the furnace. Due to the high combustion chamber temperatures of well over 1200 ° C, pollutants are destroyed or evaporated and separated by condensation or sublimation on the fly dust in the filter or in the washer.
  • the low calorific value fraction is converted into a biologically stable state in an intensive rot, whereby a rotting loss due to carbon dioxide and water vapor of about 30% arises.
  • the rotting material is not pathogenic, the smell is slight, the residual moisture is 10 - 15%, landfill gas formation and leachate formation are minimized, and the material can be used for landfill construction, as a landfill cover or as a soil conditioner in certain areas.
  • This material also contains approx. 30% calorific substance, which can be separated by sieving at approx. 40 ⁇ 20 mm. According to the fraction thus obtained is directly, with container or baling z. B. led to a coal-fired power plant, placed in the grinding dryer together with the design fuel and then burned in the large boiler.

Abstract

L'invention concerne un procédé de traitement de gaz brûlés contenant des composés polluants organiques, qui se dégagent d'installations d'incinération d'ordures. Les gaz brûlés sont mélangés sans subir de traitement préalable à des gaz de fumée issus de l'installation de chauffe fossile d'installations de chaudières industrielles et sont ainsi portés à une température supérieure à 1200 °C.
