Definitions

  • the invention relates to a method and a device for cleaning raw gas from a solid gasification with contents of granular and dusty solid particles.
  • Solid gasification means in particular the gasification of hard coal or lignite.
  • the coal can be used both as coal dust and as a slurry together with the oxidizing agent, e.g. Air or oxygen-enriched air are fed into the gasification reactor.
  • the hot crude gas obtained can either be passed through the applied coal layer or can be freely discharged in the opposite direction from the gasification reactor.
  • the invention does not relate to the purification of raw gas which is discharged through the abandoned coal layer, but only from that which is discharged freely.
  • Raw gas from solid gasification described above is not free of solids, but must be subjected to a separation of the solid parts before further processing. It is necessary to remove the solids before any further treatment of the raw gas, e.g. Cooling, to separate from this. So far, this demand could not be met or only in an inadequate form.
  • a gas cooler arrangement for cooling the reaction products of a coal gasification reactor is known.
  • the new gas cooler arrangement is intended to separate small ash particles on the pipes of the convective gas cooler.
  • the convective gas cooler comprises at least one ascent for the gas to be cooled.
  • special pipe cleaning agents e.g. Sootblower to be installed.
  • FR-E-55 473 discloses a gas generator for motor vehicles, but also for other types of use. It consists of a gasification reactor with a raw gas outlet arranged at the bottom, an ash collecting chamber, a fixed bed filter and a filter inflow chamber which connects peripherally to the raw gas outlet. Such a device is unsuitable for cleaning gases which contain sticky or liquid ash particles. Because these particles bake on the surface and in the interior of the filter, form solid layers and trigger blockages that reduce the cleaning effect of the filter and ultimately bring it to a standstill.
  • the invention is based, to remove the solid particles of any size occurring in the gasification of solids largely before entering cooling devices from the raw gas.
  • the method is carried out in a device which is characterized in that the gasification reactor has a gas outlet in the lower part, to which the filter inflow space connects peripherally, which is arranged above the fixed bed filter, the surface of the fixed bed facing the filter inflow space at least is three times larger than the circular area of the gas outlet pipe from the gasification reactor, the fixed bed is inclined and the top filter layer after covering the filter surface with dust is brought back into the ash collecting space by means of the gas backflushing by means of the nozzles.
  • the advantages achieved by the invention consist in particular in that, in terms of process engineering, the coarse and fine cleaning of the crude gas from granular and dusty solid particles takes place immediately one after the other, without interposing sensitive gas path sections or further containers. Because of the continued direct consequence of the strong gas speed reduction after the change in gas direction, there is an even flow through the following filter surface.
  • a radiation cooler 10 is installed in the lower part of the gasification reactor 1 in order to reduce the temperature of the raw gas to 500-700 ° C.
  • the raw gas flows through the radiation cooler without any noticeable deposition of solid particles on the heat exchanger surfaces.
  • the ash collecting space 5 can also be designed as a water bath.
