Definitions

  • the invention relates to a pyrolysis plant for waste and waste recycling with a heated carbonization drum, with a carbonization device on one face of the carbonization drum and a residue discharge device on the other face of the carbonization drum, with a carbonization gas outlet and with a gas converter connected to the carbonization gas outlet for converting the Smoldering gas in cracked gas.
  • the smoldering material - generally comminuted waste and waste materials - is allowed to smolder in a slowly rotating, heated smoldering drum at 400-500 ° C.
  • the resulting carbonization gas is drawn off, dedusted and converted into industrially usable cracked gas in a so-called gas converter.
  • the smoldering drum which is generally operated with a low negative pressure and rotates slowly, must be sealed on its two open end faces with ring seals with respect to the stationary smoldering material entry housing and residual material discharge housing.
  • additional ring seals are required to connect the carbonization line and to connect the heating pipe connections to the carbonization drum.
  • These ring seals which also have to absorb temperature-related axial changes in length of the smoldering drum, are subject to severe wear and tear under the given operating conditions, the relatively high temperatures, the dust and the exposure to the aggressive gases are exchanged in relatively short time intervals. The replacement of the ring seals is always associated with a shutdown of the system.
  • the heating pipes running inside the smoldering drum are also subject to noticeable wear and tear from solids carried with the smoldering material and must be replaced from time to time.
  • a special combustion chamber is to be provided in this previously known system for the production of the heating gases.
  • a smoldering drum which does not require sensitive heating pipes and which does not require a separate combustion chamber for the generation of the heating gases.
  • the exhaust gases from a power machine i.e. an internal combustion engine operated with the cracked gas used as heating gas.
  • the spiral blades which effect the axial propulsion of the carbonization material in the interior of the carbonization drum are designed as hollow bodies and the exhaust gas flows through them. The maintenance intervals for this system are determined by the many ring seals required at both ends of the carbonization drum.
  • the invention has for its object to show a way how the effort for heating the char and the maintenance intervals and maintenance costs can be reduced.
  • the heat required for the carbonization is provided with the least possible effort and without combustion of cracked gas or feeding in of external heating energy.
  • the cracked gas fed to the carbonization drum can flow through the carbonization drum for direct heating of the carbonization material in countercurrent and can be drawn off with the carbonization gas.
  • the energy balance of the pyrolysis system is improved if, in an embodiment of the invention, the cracked gas fed to the smoldering drum is passed through a heat exchanger upstream of the smoldering drum on the cracked gas side. It can be cooled down to around 550 ° C. In this way, valuable high-temperature energy is released and at the same time overheating of the smoldering drum is prevented.
  • FIG. shows: the FIG a schematic representation of the pyrolysis plant according to the invention.
  • the smoldering drum is designated by 1 in the FIG. It is open at its two end faces and rotatable about its longitudinal axis 5 on roller bearings 2, 3, 4. An electric motor 6 is provided for driving it. Between the two roller bearings 2, 3, 4, the smoldering drum 1 is provided with thermal insulation 7, 8. On its left-hand end in the illustration of the FIG, a carbonization entry housing 9 can be seen, which is connected to the The end face of the smoldering drum 1 is slipped over and connected gas-tight to the smoldering drum with an annular seal 10.
  • This Schwelguteintraggephinuse 9 carries a Schwelguteintragvortechnisch 11 with a gas-tight lock 12 and a Schwelgasabzugstutzen 14.
  • a residue discharge housing 15 On the right side in the illustration of the FIG Smoldering drum 1, a residue discharge housing 15 is slipped, which has a residue discharge device 16 with a gas-tight lock 17 and one at its lower end Fitting gas connecting piece 19 carries. This residue discharge housing also closes gas-tight with the carbonization drum 1 via an annular seal 20. Below the residual material discharge device 16, a collecting basin 21 filled with water for the residual material and a screw conveyor 22 projecting into the collecting basin for the removal of the discharged residual material and transporting the same into a transport container 23 can be seen.
  • a carbonization gas line 24 connects to the carbonization gas discharge nozzle 14 of the carbonization entry housing, which leads to a cyclone 25 and from there via a gas compressor 26 to a gas converter 27.
  • This gas converter has a combustion chamber 28, to which the carbonization line 24 and a fresh air line 29 are connected.
  • the gas converter 27 has a coke filling device 31 which is sealed by means of a lock 30 and a smoldering coke discharge device 33 which is likewise sealed by means of a lock 32 and which opens into a water bath 34.
  • a further cracked gas line 36 branches off from the cracked gas line 35 leaving the gas converter 27, which is passed over a heat exchanger 37 and connected to the cracked gas connecting piece 19 of the residue discharge housing 15.
  • town gas is passed via the connecting piece 38 of the carbonization line 24 into the combustion chamber 28 of the gas converter 27 and is burned there under substoichiometric.
  • the hot partially burned city gas leaving the gas converter 27 passes via the heat exchanger 37 and the cracked gas connection piece into the residue discharge housing 15 of the smoldering drum and from there in countercurrent to the smoldering material into the smoldering drum 1 450 ° C to 500 ° C heated.
  • the released carbonization gas is sucked by the gas compressor 26 together with the town gas through the carbonization inlet housing 9 and the carbonization line 24 into the cyclone 25, dedusted there and then pressed further into the combustion chamber 28 of the gas converter 27.
  • the carbonization gas is burned with sub-stoichiometrically mixed air.
  • the air addition is regulated so that the flame temperature is about 1000 ° C to 1200 ° C.
  • the hydrocarbons are cracked at this temperature.
  • a cracked gas is formed which essentially contains carbon monoxide, carbon dioxide, methane and hydrogen. This cracked gas is free of pollutants and can be fed to an industrial consumer and burned there without hesitation.
  • a portion of the cracked gas is returned to the smoldering drum 1 via the cracked gas line 36 and the heat exchanger 37.
  • the temperature of the about 1200 ° C hot cracked gas is cooled down to about 550 ° C before it is introduced into the smoldering drum 1. In this way, overheating of the smoldering drum is avoided and 37 process steam is generated in the heat exchanger.
  • unburned cracked gas as the heating medium saves burners and fuel costs for the generation of heating gas.
  • the direct introduction of the cracked gas into the interior of the carbonization drum saves on ring seals that require maintenance. In the system according to the invention, only one ring seal each is required on the carbonization entry housing and residue discharge housing.
  • the direct transfer of the cracked gas into the smoldering drum 1 optimizes the heat transfer from the cracked gas used as a heat transport medium to the smoldering material. The amount of heat required for this is further reduced by the thermal insulation 7,8 of the carbonization drum 1.
  • the gas quantities and thus also the deposition conditions for the cyclone 25 installed in the carbonization gas line 24 are improved.
  • the heat released in the heat exchanger 37 is high-temperature heat and can be used for process steam generation and for internal heating purposes.
