Definitions

  • the invention relates to a method for disposing of waste, the waste being carbonized so that carbonization gas and solid carbonization residue are obtained, the carbonization gas is burned, and the carbonization residue is divided into a coarse and a fine fraction.
  • the invention also relates to a device for the disposal of waste with a waste feed device which opens into a carbonization drum, from which a carbonization gas discharge and a carbonization discharge tube originate, the carbonization gas discharge line being connected to a combustion chamber which has a flue gas outlet, and wherein the carbonization residue discharge line is connected to a Separator is connected, which has derivatives for a coarse and a fine fraction.
  • Such a method and such a device for thermal waste disposal are known from European Patent 0 302 310 B1.
  • This device has a smoldering drum into which the waste to be disposed of is introduced. The waste is carbonized there and carbonization gas and a solid carbonization residue are released. The carbonization gas is fed directly to a combustion chamber.
  • the smoldering residue is divided into a coarse and a fine fraction, and the fine fraction is fed into the combustion chamber like the smoldering gas, possibly after a grinding process.
  • the substances fed in are burned at high temperatures. This creates molten slag that is discharged into a water bath.
  • flue gas is emitted, which is subjected to flue gas cleaning.
  • EP 0 523 815 A1 discloses a process for producing a synthesis or fuel gas from pyrolysis coke, which is produced when waste materials are charred. This synthesis or fuel gas is cleaned and can then be used as an energy source in a power plant.
  • a method and a device for producing synthesis gas from a pyrolysis residue, which arises during the carbonization of residues, for example packaging materials, is also known from the subsequently published EP 0 563 777 A2. In this case, too, the synthesis gas is subjected to a cleaning process before it is used again. In the processes known from these two publications, the focus is therefore not on cost-effective and as complete as possible disposal of waste materials, but rather on the generation of an energy source.
  • the invention had for its object to provide a method of the type mentioned above for the disposal of waste, which can be carried out more cheaply compared to the known.
  • a device of the type mentioned at the beginning should be specified, which can be produced more cost-effectively than the known device.
  • smaller amounts of flue gas should be generated during the process and / or during the installation.
  • the object of specifying an inexpensive method is achieved according to the invention in that the fine fraction is subjected to gasification, in that the temperature is above the melting temperature of those substances be subjected to gasification and which are non-combustible, so that synthesis gas and molten slag are obtained and that the synthesis gas is burned unpurified.
  • the fine fraction of the smoldering residue is first gasified and then only the synthesis gas formed is burned, one advantageously manages with a small combustion chamber capacity. It is already guaranteed during the gasification process that, due to the high temperature, all non-combustible substances of the fine fraction become molten and are separated from the gasifier as molten slag. Only the combustible substances of the fine fraction, for example all carbon-containing substances, are gasified and later burned. The amount of fine fraction of the smoldering residue corresponding to the slag does not therefore get into the combustion chamber. Otherwise in the method according to the invention advantageously only gas burned. Due to the fact that on the one hand only gases and no solid substances and on the other hand relatively small amounts are burned, only a small amount of flue gases are produced which are generally cleaned and then released. This is a particular advantage.
  • the synthesis gas can be burned separately, for example, but also together with the carbonization gas from the carbonization drum. In the latter case, only a single combustion chamber is required, which can be made small and inexpensive due to the separation of the slag in the gasification process.
  • the combustion can take place, for example, with the supply of air enriched with oxygen. This improves the combustion process. Pure oxygen can also be added.
  • the fine fraction of the smoldering residue is either supplied with oxygen-enriched air or even pure oxygen during gasification.
  • oxygen-enriched air can contain, for example, 70% oxygen.
  • gasification for example, a temperature of approximately 2000 ° C. can be present in the gasifier.
  • the synthesis gas consists largely of carbon monoxide, which can then be burned.
  • the carbonization gas emitted by the carbonization drum is washed.
  • the scrubbed carbonization gas is then burned and the sludge separated during washing can be gasified.
  • flue gas When synthesis gas and carbonization gas are burned, flue gas is produced; This can be freed of dust during flue gas cleaning.
  • This dust is, for example, supplied to the already existing carburetor and gasified there. This ensures that the dust from the flue gas is incorporated into the molten slag.
  • the molten slag is introduced into a water bath from a gasifier, for example.
  • a melting granulate that is harmless to the environment and can be used as a building material, for example.
  • the object of specifying an inexpensive waste disposal device is achieved according to the invention in that the discharge of the separation device for the fine fraction is connected to a gasifier, from which a synthesis gas discharge, which is connected directly to a combustion chamber, and a slag discharge going out.
  • the advantage is achieved that, apart from the carbonization gas, only synthesis gas has to be fed to a combustion chamber. You therefore get by with a small and therefore inexpensive combustion chamber. This is due to the fact that on the one hand the solid constituents of the fine fraction of the smoldering residue are already separated in the gasifier and on the other hand almost only gases are fed to the combustion chamber. This also means that little flue gas is produced, which yes - preferably after flue gas cleaning - has to be released. As a result, a smaller flue gas cleaning device can be used. There may also be two small combustion chambers, one for smoldering gas and the other for synthesis gas.
  • the smoldering gas discharge of the smoldering drum and the synthesis gas discharge of the carburetor can open into separate combustion chambers or into the same combustion chamber.
  • the carburetor has, for example, a supply line for oxygen-enriched air or for pure oxygen.
  • the supply of oxygen ensures a high temperature in the carburetor.
  • the carbonization line of the carbonization drum can be connected to a first gas scrubber, from which a line for washed carbonization gas and a line for sludge originate.
  • the line for the washed carbonization gas can be connected to the combustion chamber and the line for the sludge to the gasifier. This ensures that the carbonization gas is cleaned before entering the combustion chamber.
  • the separated sludge can be removed or preferably gasified together with the fine portion of the smoldering residue in the gasifier.
  • the combustion chamber is thereby largely kept free of solid substances, so that a simple design of the combustion chamber is sufficient.
  • a flue gas cleaning device is preferably connected, the dust outlet of which is connected, for example, to the carburetor. This advantageously introduces dust from the flue gas into the gasifier, where, if it is not gasified, it is incorporated into the molten slag.
  • a heat exchanger can be connected downstream of the flue gas outlet, for example, in order to obtain thermal energy from the hot flue gas.
  • the slag discharge of the carburetor can lead into a water tank, so that a melt granulate is formed there, which can serve, for example, as a building material.
  • the advantage is achieved that the fine fraction of the smoldering residue and optionally also sludge and dust are first gasified, as a result of which flammable synthesis gas and melt granules are obtained.
  • the melt granulate can be used as a raw material.
  • the synthesis gas is burned separately or together with the carbonization gas from the carbonization drum. Since no solid substances have to be burned, it is advantageous to use a simply constructed, small and inexpensive combustion chamber. As a result, there is little flue gas to be released and only a small flue gas purification device is required.
  • the waste A to be disposed of is fed via a waste feed device 1 a to a carbonization drum 1, where it carbonizes and is thereby divided into carbonization gas SG and carbonization residue SR.
  • a carbonization line 2, 2 ' connects the carbonization drum 1 to a combustion chamber 3.
  • a carbonization line 4 connects the carbonization drum 1 to a separating device 5, in which the carbonization residue SR is divided into a coarse fraction GR and a fine fraction FR.
  • the coarse fraction GR essentially contains metal parts, glass and stones.
  • the fine fraction FR essentially contains carbon-containing smoldering residue.
  • the separating device 5 can be designed as a sieve.
  • a derivation 5a for the coarse fraction GR and a derivation 6 for the fine fraction FR of the smoldering residue SR originate from the separating device 5.
  • the derivative 6 for the fine fraction FR leads to a carburetor 7.
  • the carburetor 7 only needs to be heated externally to start up the device. During operation, a subset of the supplied goods is burned, which is necessary Provides thermal energy for the gasification of the remaining carbon-containing material.
  • the carburetor 7 is supplied with oxygen-enriched air L or pure oxygen via an air supply line 8. This results in a very high temperature in the carburetor 7, which can be 2000 ° C. At this temperature, which is above the melting point of all non-combustible feed materials, the fine fraction FR fed in of the smoldering residue SR is converted into molten slag S and a synthesis gas SY.
  • the molten slag S is discharged from the gasifier 7 via a slag discharge 9 and enters a water tank 10, where a melt granulate is formed.
  • the melt granulate can be used as a raw material.
  • the synthesis gas SY leaves the carburetor 7 via a synthesis gas discharge line 11 which leads to the combustion chamber 3.
  • the synthesis gas SY is burned together with the carbonization gas SG in the combustion chamber 3. Separate combustion of gases SG and SY is also possible. Since only gases are supplied to the combustion chamber 3, an inexpensive small combustion chamber 3 is sufficient.
  • the combustion chamber 3 can be supplied with oxygen-enriched air L * or pure oxygen via an air supply line 12. Complete combustion takes place in the combustion chamber 3.
  • a flue gas discharge line 13 for flue gas RG extends from a flue gas outlet 3a of the combustion chamber 3 and leads to a chimney 16 via a heat recovery steam generator or heat exchanger 14 and a flue gas cleaning device 15 which has a dust outlet 15a.
  • a first gas scrubber 17 can be arranged in the carbonization line 2, 2 'of the carbonization drum 1. Sludge SCH separated there arrives in the gasifier 7 via a sludge discharge line 18. A section of the leads from the first gas scrubber 17 Smoldering gas discharge line 2 ', through which washed smoldering gas SGW flows, to the combustion chamber 3. The first gas scrubber 17 ensures that the combustion chamber 3 remains free of solid impurities in the smoldering gas SG.
  • the synthesis gas SY can be fed to the combustion chamber 20a of a gas engine 20 via a separate synthesis gas discharge line 19, 19 ′ (shown in broken lines) and burned there. Combustion in both combustion chambers 3, 20a is also possible.
  • a second gas scrubber 21 can be inserted into the synthesis gas discharge line 19, 19 ′, but also into the synthesis gas discharge line 11. Washed synthesis gas SYW then arrives in the combustion chamber 20a or 3. This ensures that solid components which may be in the synthesis gas SY do not get into the combustion chamber 3 or into the gas engine 20. These solid components get back into the carburetor 7 as sludge SC via a sludge drain 22.
  • the gas engine 20 can drive a generator (not shown).
  • a flue gas discharge line 23 (dashed line) starting from a flue gas outlet 20b of the gas motor 20 is connected to the inlet of the flue gas cleaning device 15, which receives the flue gas RG 'emitted. Dust ST separated in the flue gas cleaning device 15 and also dust ST separated in the heat recovery steam generator (heat exchanger) 14 can be supplied to the carburetor 7 via dust discharge lines 25, 24.
