Definitions

  • the invention relates to a method for thermal treatment of volatile, flammable components Insert material with a water content of up to 20% by weight, where the insert material with hot granular solids, that come from a collection bunker in a pyrolysis reactor mixes, withdraws gases and vapors from the reactor and in the reactor generates a solid mixture, which one from the reactor dissipates, at least part of it outside the Heated and over the collection bunker in the Pyrolysis reactor returns.
  • DE-A-29 46 102 and DE-A-25 37 732 disclose both a method according to the preamble of claim 1.
  • DE-A-29 46 102 additionally reveals the possibility of inserting material in the middle Area of the trickle zone.
  • the invention is based, from which Use a gas with the highest possible calorific value win that is completely or largely tar-free and therefore only a low content of condensable organic Has components. According to the invention this object is achieved by the characterizing features of claim 1.
  • the hot granular solids are also referred to below as Heat transfer solids called.
  • the insert material is at the same time one or more posting points in the trickle zone of the Pyrolysis reactor headed. Reached at multiple drop-off points a pre-distribution of the fed material.
  • the moist material is represented by 1 to 6 Guide the feed points into the reactor.
  • the drop-off points can flow into the middle or lower area of the trickle zone.
  • the pyrolysis reactor is expedient and in particular also its trickle zone free from rotating mixing devices in order Exclude wear problems as far as possible.
  • the trickle zone can be divided by a fixed roof-like installation and multiple deflection of the trickling streams of solids and so bring about their rapid mixing.
  • a height of 1 to 10 m is recommended for the trickle zone, the height depending on the material used and the temperatures, especially in the trickle zone. This results in or from the fluidized bed Moving bed of rising gases and vapors in the trickle zone Residence times in the range from 0.5 to 20 seconds and mostly 1 up to 10 seconds. With increasing temperature the Speed of the cracking reactions, so that at high Temperatures with shorter dwell times can be worked.
  • the insert material is in from the outside fed the middle or lower area of the trickle zone, but while you put the hot granular solids in the top Area of the trickle zone. This is how the ascending come Gases and vapors in the upper area of the trickle zone only with the hot solids in contact. At a given crack temperature can the necessary residence time of the gases and vapors in the Trickle zone can be reduced or the temperature of the feed solids are lowered.
  • the collection bunker may also be advisable to use the collection bunker to further increase the temperature of the heat transfer solids before they are fed into the pyrolysis reactor.
  • an O 2 -containing gas eg air
  • combustion can be provided there, which increases the temperatures in the desired manner.
  • a pyrolysis reactor (1) leads a pyrolysis reactor (1) according to the invention through the line (2) the feedstock to be treated and through the line (3) hot granular solids as heat transfer medium.
  • the line (2) branches into several before entering the reactor (1) Drop-off points (2a) and (2b).
  • the trickle zone (1a) In the upper area of the reactor (1) is the trickle zone (1a), below that forms the Solid mixture (4) a moving bed or fluidized bed.
  • a sighting gas e.g. B. Nitrogen or water vapor
  • the trickle zone is fixed Deflection devices in the form of several roof-like internals (8) on. A rotating mixing device is used waived.
  • the hot granular solids that collect in the lower area of the bunker (22) have temperatures of 700 to 1100 ° C. If these temperatures are not already reached in the pneumatic conveying section (20), an O 2 -containing gas (e.g. air) can be supplied to the bunker (22) through the line (28) and the temperatures in the bunker can be increased by post-combustion .
  • the gas supply through line (28) can also be used to remove dust-fine solids by sifting these dusts through line (23) to separator (24) and through line (26) from the circuit away.
  • Fig. 2 shows an embodiment of the Pyrolysis reactor (1) with countercurrent flow of the hot Heat transfer solids and the gases and vapors formed above the mouths of lines (2a) and (2b) through which the feed material is fed.
  • the heat transfer solids come from line (3); the other reference numbers have the already explained together with FIG. 1.
  • a pyrolysis reactor (1) as shown in Fig. 2, 5 t of dried sewage sludge with a residual moisture content of 7 wt .-% are fed through line (2) per hour.
  • the sewage sludge consists of 63% by weight of volatile components, it has a lower calorific value of 17.0 MJ / kg.
  • the reactor (1) is fed 80 t / h hot heat transfer solids at 900 ° C through line (3). This produces 2920 Nm 3 / h, 850 ° C hot pyrolysis gas with a lower calorific value of 23.3 MJ / Nm 3 which is discharged through line (9), dedusted in the cyclone (10) and then fed to gas cleaning (16).
