Definitions

  • Hard coal briquetting was used in the past mainly for the production of particulate carbon carriers made of fine coal for use as a domestic fire or in industrial grate firing. There are therefore numerous methods of hard coal briquetting known. Hard coal briquetting is very important for the COREX® / FINEX® process for the production of molten pig iron, since this process is based on a fixed bed process in which the fixed bed is produced by lumped carbon carriers.
  • melt reduction process lumped carbon carriers are charged together with prereduced iron carriers and additives to the fixed-bed surface of a so-called melt-down gasifier.
  • the pre-reduced iron carriers are completely reduced and a molten pig iron and a molten slag is produced, which is obtained from time to time by tapping.
  • the necessary for the melting heat is through Gasification of the lumped carbon carriers provided by means of oxygen.
  • the resulting hot gases penetrate the fixed bed with the release of heat and leave the fixed bed on the fixed bed surface.
  • molten pig iron and molten slag seep through the fixed bed and collect in its lowest area, the so-called swamp.
  • the briquetting of cold and hot strength of the lumped carbon carriers produced by briquettes can be favorably influenced by the nature of the process used and the characteristics of its performance.
  • a heat treatment for example, a heating -, which may be one or more stages, the briquettes after pressing.
  • the strength properties of the briquettes can be influenced in terms of curing.
  • the mixing can be carried out under batchwise addition of material or with continuous addition of material.
  • exhaust steam produced during the direct or indirect interaction is used at least as a partial amount of the water vapor added during the mixing. It can be used in such a way the entire exhaust steam or part of the resulting exhaust steam. As a result, the efficiency of the method is increased because the exhaust steam is energetically and materially used for heating and as a solvent for the binder system in the mixing.
  • the binder system is mixed in the liquid state with the carbon carriers; This is especially used for liquid binder systems.
  • the binder system is mixed with the carbon carriers in a first mixing step to form a premix, and subjecting the premix to a second mixing step with the addition of water vapor. Then the steam meets an already largely homogenized mixture of carbon carriers and binder system.
  • exhaust steam occurring in this interaction is used at least as a partial amount of the water vapor added during the mixing. This has the advantage that it is introduced materially and energetically back into the process.
  • the carbon carriers are added to the hot strength of briquette increasing components in an amount of 1 to 10 mass%, based on the mass of the carbon carriers supplied to the mixing.
  • These may be, for example, bitumens in granular form or as droplet spray, dusts / sludges from metallurgical processes, coals with elevated hot strength compared with the carbon supports.
  • the mixture is subjected to a pre-agglomeration before it is subjected to compression to briquettes.
  • pre-agglomerated mixture brings advantages in terms of the properties of the briquettes, especially a higher density, which leads to firmer briquettes.
  • Another object of the present application is a method in which the binder system contains polyvinyl acetate, wherein the polyvinyl acetate is at least partially generated from monomers which is based on a synthesis gas, which is based on in the inventive method for producing pig iron with gasification of the carbon carrier resulting export gas , Be obtained with conversion of CO of the synthesis gas via acetic acid in vinyl acetate.
  • the device for changing the temperature of the carbon carriers prior to entry into the mixing device can be designed, for example, as a heatable chamber.
  • the dryer is the device for changing the temperature of the carbon carriers before entering the mixing device. This reduces the expenditure on equipment, maintenance, and investment and operating costs.
  • the heat treatment device for heat treatment of the briquettes may be formed, for example, as a heatable chamber.
  • the carbon carrier storage is provided with a device for changing the temperature of carbon carriers located in the carbon carrier storage. This allows no extra aggregate to be needed to change the temperature of the carbon carriers.
  • the premixer comprises means for changing the temperature of premixing in the premixer; for example, by a heat transfer medium such as steam or thermal oil flowed through or electrical heating elements.
  • a heat transfer medium such as steam or thermal oil flowed through or electrical heating elements.

  • the efficiency of the method according to the invention can be increased by optimally adjusting the treatment conditions to the mixture to be briquetted.
  • the exhaust steam line opens into the steam inlet line and / or into the mixing device. According to another embodiment, the exhaust steam line opens into the final mixer.
  • the device according to the invention also comprises a device for pre-agglomeration of the mixture produced in the mixing device. This is then connected via a mixture supply line to the mixing device, and connected to a Voragglomeratabtechnisch with the pressing device for pressing briquettes.

  • the carbon carriers 2, in this case a mixture of fine carbons of different origin and different grain size, are subjected in the mixing device 1 with a binder system 3, in this case starch powder, to a mixture with the addition of water vapor.
  • the resulting mixture is then subjected to pressing in the pressing device 4 into briquettes. Drying in the drier 6 takes place up to a water content of less than or equal to 7% by mass.
  • the drying of the carbon carriers prior to mixing and the heat treatment of the briquettes after the pressing takes place by means of superheated steam supplied via the steam feed lines 8a, 8b.
  • the resulting exhaust steam is introduced via the exhaust steam line 9a in the water vapor feed line 5 and the exhaust steam line 9b in the mixing device 1, where it is a subset of the added during mixing water vapor.
  • the dryer 6 is at the same time a device for changing the temperature of the carbon carriers prior to entry into the mixing device.
