Definitions

  • the invention relates to a method and a device for treating carbon-containing adsorbent, which passes through a reactor of a flue gas cleaning system, a desorption treatment being carried out and the desorption gas formed thereby being subjected to heavy metal separation .
  • the invention is therefore based on the object of making the treatment more economical and simpler in terms of apparatus without reducing the quality of treatment.
  • the process according to the invention is characterized in that the carbonaceous adsorbent is passed through the reactor in an upstream and at least one outflow layer and that the adsorbent of the upstream layer is discharged separately from the reactor and is subjected to the desorption treatment alone.
  • the invention is based on the knowledge that, due to the high reaction rate, the heavy metals practically predominantly settle in the upstream layer of the adsorbent. Accordingly, the invention creates the possibility of discharging this upstream adsorbent layer separately and subjecting it to the desorption treatment alone. This is therefore only applied to a fraction of the total adsorbent. The energy expenditure for heating is correspondingly lower. The size of the treatment device is also reduced considerably. This leads to a small footprint and a reduction in investment costs.
  • ATZBL ⁇ TT RULE26 Oven coke is preferably used as the carbon-containing adsorbent, it being particularly advantageous to add the adsorbent to the upstream layer after the desorption treatment and to burn it together with the other adsorbent.
  • the desorption gas is preferably also burned together with the adsorbent.
  • the invention further relates to an arrangement for carrying out the method according to the invention, this arrangement comprising a flue gas cleaning reactor, an adsorbent discharge device for the reactor, a desorption device downstream of the discharge device with desorption gas outlet and adsorbent outlet, and a connection to the desorption gas outlet.
  • NEN heavy metal separator includes.
  • the system is characterized in that the reactor has at least one partition for dividing an upstream adsorbent layer, that the discharge device has a main department and a secondary department assigned to the upstream adsorbent layer, and that only the secondary department to the Desorption device is connected.
  • the adsorbent outlet of the desorption device be connected to the outlet of the main department of the discharge device and be connected together with the latter to a combustion device.
  • the gas outlet of the desorption device is preferably also connected to the combustion device.
  • REPLACEMENT BLA ⁇ (RULE 26) be laid and gets by with a low-performance heating.
  • the arrangement has a reactor 1 which is provided for flue gas cleaning.
  • a reactor 1 which is provided for flue gas cleaning.
  • it contains a bed made of carbon-containing adsorbent 2, which is a fixed bed or a moving bed.
  • the adsorbent is removed from the reactor 1 via a discharge device 3.
  • a partition 4 is arranged in the interior of the reactor 1, which divides an upstream layer 5 of adsorbent 2.
  • a secondary department 6 of the discharge device 3 is assigned to this layer 5.
  • the remaining adsorbent 2 leaves the reactor 1 through a main section 7 of the discharge device 3.
  • the secondary section 6 of the discharge device 3 is connected to a desorption device 8. This is where the pollutants absorbed in the reactor 1 are desorbed. It has been found that the major proportion of the pollutants is deposited in the upstream layer 5 of the adsorbent 2 and that it is sufficient to subject this material to the desorption treatment 8 in order to achieve satisfactory cleaning results.
  • Desorption device 8 therefore only has to treat a small proportion of the adsorbent 2 and can accordingly be of small dimensions. It also only requires a low heating output.
  • the desorption device 8 has a desorption gas outlet 9 which is connected to a heavy metal separator 10
  • the desorption device 8 also has an adsorbent outlet 11 which is coupled to the main section 7 of the discharge device 3 and is connected together with the latter to a combustion device (not shown).
  • the carbon-containing adsorbent 2, which is hearth furnace coke, is thus completely burned, together with the desorption gas, since the heavy metal separator 10 is also connected to the combustion device.
  • the reactor 1 thus contains a total of 3 layers of the adsorbent 2. If appropriate, 2 layers are sufficient. However, a large number of layers can also be considered. Each of the layers can have its own department of
  • Discharge device 3 are available.
  • the upstream layer 5 is shown relatively narrow. If necessary, it can be much thicker or even narrower.
  • all layers are charged with relatively cheap hearth furnace coke, in which regeneration for a renewed use is hardly worthwhile. Deviating from this, other adsorbents can also be used.

Abstract

L'adsorbant (2) est introduit dans un réacteur (1) d'une installation d'épuration des gaz de fumées, une paroi séparatrice (4) divisant une couche (5) côté écoulement latéral. Seul l'adsorbant de cette couche parvient dans un dispositif de désorption (8), dont le gaz de désorption est envoyé vers un séparateur de métaux lourds. Après traitement de désorption, l'adsorbant de la couche (5) est rassemblé avec l'adsorbant restant et brûlé. De même, après séparation des métaux lourds, le gaz de désorption est brûlé.
