Definitions

  • the present invention relates to a DC shaft reactor for Melting and gasifying feedstocks of different types and Consistency, such as pollutant-free and / or contaminated woods, house and Bulky waste, alternative fuels, pelletized dusts or animal meal, Plastics, industrial and commercial waste.
  • feedstocks of different types and Consistency such as pollutant-free and / or contaminated woods, house and Bulky waste, alternative fuels, pelletized dusts or animal meal, Plastics, industrial and commercial waste.
  • a synthesis gas which is used to generate electrical energy and heat is suitable and / or as a basis for Synthesis processes are used.
  • a solid product creates a non-leachable slag and a materially processable Metal phase or a non-elutable liquid phase, which for a further processing is available.
  • a coke-heated cycle gas cupola is used material and / or energy recovery of waste materials described. It consists of a vertical furnace shaft with below the Facing large volume recycle gas vents through Channels and nozzles are connected to the melting and overheating zone, above which a large volume excess gas extraction level resulting gas from the process.
  • the furnace shaft part between recycle gas and excess gas suction opening queritessverjüngt is the furnace shaft part between recycle gas and excess gas suction opening quer4.000sverjüngt.
  • the heat transfer takes place as in DE 43 17 145 C1 due to the fact that the feedstock rises upwards in the countercurrent principle Process gases.
  • the multiple countercurrent flow of the gas through the moving bed allows despite some modifications by narrowing the cross-section in the shaft and expanding the cross-section in the Gas discharge does not mean processing a wide range of feed.
  • DE 198 16 864 A1 describes a cycle gas cupola, in which an excess gas extraction below the melting and Overheating zone is arranged. This results in a Counterflow gasification and heat transfer in the upper furnace shaft area, where the gas is sucked off through large-volume openings and through Channels / nozzles are directed into the melting and overheating zone. In the Subsequent DC gasification turns the gas at high temperatures reduced and longer-chain hydrocarbons split. Through this The chosen arrangement is the negative influence of short-circuit currents reduced. The spatial proximity of the endothermic processes to the range and the large-volume excess gas extraction removes from the melt necessary heat to the necessary under all operating conditions to ensure liquid discharge of the melt.
  • DE 100 07 115 A1 describes a reactor for gasifying and / or melting Feedstocks with a feed, pyrolysis, melting and Overheating section described.
  • the pyrolysis section has one Cross-sectional expansion as a gas supply space in which at least one Combustion chamber with at least one burner, through which hot Combustion gases are fed to a bulk cone that forms.
  • high-energy media are created using upper and lower Injection agents in the area of the melting and overheating zone as well introduced above the melt by means of oxygen lances and / or nozzles.
  • the disadvantage of this device is that it is enlarged by the cone Reactor surface in the area of the cross-sectional expansion of the pyrolysis, because Heat losses occur.
  • the object of the invention is a DC shaft reactor to create with that even when using different input materials
  • the inventive DC shaft reactor for melting and Gasification of feedstock has a vertical shaft body.
  • the feed material is dried and heated within the shaft body and gasified.
  • the shaft body can therefore usually be divided into the areas Divide the drying zone, degassing zone and gasification zone.
  • To the The shaft body is followed by a receiving body, which is used to hold molten feed. Within that body is the Melting zone of the reactor formed.
  • the shaft body and / or the Receiving bodies are equipped with a gas discharge device for removing the Produced useful gases generated within the reactor.
  • the Discharge device in the area between the shaft body and the Arranged body and designed as a tube.
  • the vertically aligned shaft body on a feed device through which the Feed material is fed to the shaft reactor.
  • a gas supply device for the Supply of gas connected to the manhole body.
  • the gas supplied at which is preferably air or oxygen-enriched air acts to dry the feed.
  • To be good and effective To achieve drying of the feed is the gas supplied preheated according to the invention.
  • To preheat the gas According to the invention, the gas supply device with the gas discharge device connected.
  • the hot gas discharged from the reactor is according to the invention thus used to preheat the gas supplied to the shaft body.
  • a lock arrangement is arranged downstream of the feed opening of the reactor, that controls the feeding of the feed. In the field of Lock arrangement is at least part of the gas supply device with the Lock chamber connected.
  • the use of the invention dissipated gas as an energy source leads to the preheating of the Gases no additional energy is required and the feed already undergoes a first drying in the lock arrangement.
  • the Lock arrangement is thereby in addition to drying the Input material used.
  • Another significant advantage of the invention is that heat is extracted from the gas that is removed. This is the further processing or use of this gas is simplified.
  • Feed material can be processed in the shaft reactor, because the Feed material stronger during his stay in the shaft reactor is heated and thus also with poorly processable materials Degassing and gasification can be achieved. In particular, this also means achieved that better degassing and gasification within the reactor takes place so that the useful gas has fewer particles.
  • inventive design of the DC shaft reactor possible to produce useful gases that have a significantly lower oil and Tar content and a significantly lower pollutant content.
  • the feed material is introduced into the shaft body via the Lock arrangement.
  • the Lock arrangement preferably has at least one lock chamber on. A first lock gate is thus opened in order to insert the feed material in bring in the lock chamber. Then this first lock gate closed so that the lock chamber is closed. In this Condition may contain any air contained in the lock chamber and / or be replaced by another gas. Then the second Lock gate leading towards the interior of the shaft reactor, opened and the feed material comes from the lock chamber into the Reactor.
