Definitions

  • the invention relates to a method for separating the coal water obtained in the coking process into a small salt-rich and a large salt-poor fraction according to the preamble of claim 1.
  • the approximately 800 ° C hot gas coming from the riser pipe is cooled in the receiver by circulating gas condensates to the dew point at approximately 80 ° C.
  • the invention is therefore based on the object to remove the non-deposited fixed salts in the pre-coolers from the gas in the pre-coolers in order to obtain most of the water obtained in the coking without salt and after further cleaning steps as process water in the To be able to reduce coke oven operations.
  • the invention will be described in more detail with reference to the drawing.
  • the figure shows schematically the gas cleaning after the coke ovens.
  • the circulation of the tar and water condensed in the template 1 takes place via line 2 to the tar separator 3 and further via line 4 back to the template 1.
  • the gas flow enters the precooler 6 from the template 1 through the electrostatic filter 5.
  • the outflow of the electrostatic filter 5 is conducted via line 7 into the template circuit, for example into the tar separator 3.
  • a condensate is obtained in the pre-coolers 6, which is practically free of fixed salts and is further processed separately.
  • Part of the precooler condensate is via line 8 in the template circuit, for. B. as shown here, returned to the template 1, since in addition to the coal water, the water vapor is condensed out, which was previously evaporated in the template 1 for cooling the hot raw gas.
  • the amount of water drawn off from the supply circuit through line 9 can be freed of its volatile achad substances, for example, in a stripper, and also fixed ammonia when lime, sodium hydroxide solution or sodium carbonate are added, and can be removed after de-phenolization. Since this is a comparatively small amount of water, this solution can also be evaporated in order to obtain the fixed salts as a solid.
  • the condensate obtained in the pre-coolers is freed of its volatile pollutants, if necessary after use in gas cleaning, and can be used after further biological cleaning, reverse osmosis, after de-phenolization or cleaning with activated carbon as process water, e.g. for coke quenching or as cooling water , used in the coking plant.
  • fractional condensation of the gases is carried out in a number of precoolers 6 according to one embodiment of the invention.
  • the gas in the first cooler is only cooled to such an extent that the condensed water (at around 70 ° C) can be used as process water.
  • Ambient temperature becomes a second cooler sprinkled with tar or a tar-ammonia water mixture to avoid naphthalene deposits.
  • the flow of the second cooler is then through line 8 in the template circuit, for. B. returned to template 1.
