Definitions

  • the invention relates to a method according to the preamble of claim 1 and an apparatus for performing the method.
  • Printing paste waste arises in textile and paper printing plants due to losses in the production of printing pastes, spilling and in the operation and cleaning of the printing machines. There are also residues in containers and supply lines, as well as contaminated or otherwise unusable excesses.
  • This waste consists essentially of dyes, V erdickungs-, solution and fixing.
  • Similar, predominantly organic, aqueous and / or solvent-containing, concentrated waste can be found, for example, in textile dyeing plants in the form of residual liquors, in textile pretreatment in the form of concentrates during desizing or in textile aftertreatment in the form of waste from coating baths. Similar waste is also found in other industries, for example as bituminous waste or as sewage sludge.
  • the invention has for its object to improve the known method so that the waste materials can be destroyed by thermal treatment without the risk of contamination.
  • the waste color paste is converted into a residue that can be easily deposited.
  • the calorific value of the combustible components contained in the color paste waste can be at least partially exploited.
  • FIG. 1 An embodiment of the invention is shown in the drawing and is explained in more detail below.
  • the drawing shows schematically a device according to the invention.
  • a rotary drum 1 is guided transversely through a channel 2 through which hot gases flow and is sealed off from it.
  • the temperature of the gases is preferably about 450 to 550 ° C.
  • Channel 2 can be the last flue gas flue from a two- or three-pass boiler.
  • the rotary drum 1 can also be arranged in a lockable bypass channel to the flue gas duct. This bypass duct is parallel to the heating surfaces of the flue gas duct and opens into the flue gas duct before the last heating surface.
  • the rotary drum 1 is mounted in two bearings 3 arranged outside the channel 2.
  • the rotary drum 1 is driven by a motor 4 and a gear 5.
  • a feed line is guided into the entry end of the rotary drum 1.
  • the feed line 6 is connected to a storage container 7 and equipped with a pump 8.
  • the discharge end of the rotary drum 1 opens into a calming space 9 arranged outside the channel 2.
  • the calming space 9 has a funnel 10 which is closed off by a discharge element 11.
  • the calming chamber 9 also serves as a collection bunker for the dust separated by the calming of the gas flow.
  • the calming space 9 is connected to a gas discharge line 12, which enters a fine separator, for example a cyclone 13.
  • the gas exhaust pipe 14 leaving the cyclone 13 is connected to the combustion chamber (not shown) of the boiler mentioned.
  • the gas exhaust pipe 14 can also be led to the flue gas flue of the boiler equipped with touch heating surfaces and soot blowers or to a torch burner.
  • the waste materials for example the color paste, are collected in the storage container 7 and are continuously fed from there to the rotary drum 1 via the pump 8.
  • the rotary drum 1 is heated by the flue gas flowing within the channel 2, the temperature level of which is preferably between about 450 and 550 ° C. At this temperature level, all are in the waste materials contained hydrocarbons pyrolyzed and converted into the vapor or gaseous state. What remains is a solid residue that has become non-toxic and inactive as a result of this thermal treatment.
  • the solid residue is discharged with the gases and vapors and separated out in the calming chamber 9 and the cyclone 13 connected downstream. This residue consists of inert material and pure activated carbon and can be landfilled without any problems.
  • the cleaned gases and vapors are flammable and are introduced into the combustion chamber of the boiler, and if possible integrated into a burner system. If it is a traveling grate boiler, these gases and vapors can be introduced into the flame chamber without special equipment. In cases in which it is feared that the gases, despite the previous cleaning, still contain constituents which could be deposited on the cooled surfaces and thus lead to contamination, the gases are fed to the subsequent touch train. These trains can be kept clean with simple soot blowers. The flaring of the gases is also possible in a separate deduction.
