Definitions

  • the invention relates to a method for wet quenching of hard coal coke in particular according to the preamble of claim 1.
  • the invention also relates to a device for carrying out the new method.
  • the coke When extinguishing, the coke absorbs water because the extinguishing water can penetrate the pores of hot coke unlike cold coke.
  • the requirements of the smelters for the coke pieces have become lower because a coke with a grain size of more than 25 mm is considered suitable for iron production.
  • the requirements for the final water content of the coke are still strict.
  • the customers demand compliance with a specified minimum final water content in the coke, not least because exceeding the water content leads to losses of usable coke mass.
  • maintaining the relatively low final water content in coke is more difficult with fine coke than with coarse coke.
  • the object of the invention is to extinguish the coke in such a way that low emission values in the extinguishing swaths can be maintained or even fallen below.
  • the dust particles are washed out of the resulting water swaths in a very dense water curtain, which in turn prevents dust particles from entering the area of the Extinguishing tower can get above the fire hood.
  • the amount of water can be greatly reduced because after the coke surface has been extinguished, no more dust particles are produced.
  • the fine coke is also less moistened, so that the final water content can be maintained or fallen below.
  • the method according to the invention is carried out according to the feature of claim 2.
  • the emissions caused by the buoyancy and the hot coke surface are also avoided.
  • the lower part of an extinguishing tower, generally designated 1, is designed as a fire truck hall 2.
  • the coke-extinguishing car with the fire 4 shown generally and schematically at 3 in FIG. 2 can be run in.
  • Extending above the hall 2 is an extinguishing hood 5 forming the lower part of the tower, in which a plurality of horizontal pipelines 6 are laid, which have nozzles 7 on their upper side for the discharge of extinguishing water.
  • the pipes 6 run as shown in FIG. 2 in the longitudinal direction of the fire truck track in hall 2.
  • the pipes 6 are arranged at an uneven distance corresponding to the coke layer height in the fire truck 3, ie the density of the pipes 6 is in the left part of FIG. 2 larger than the one on the right. This ensures that the coke is evenly sprinkled when it is extinguished.
  • the pipes 6 are acted upon by right-angled pipes 8 and 9 and a riser 10 with extinguishing water.
  • the riser pipe 10 is connected via a bend 11 to a down pipe 12, which can be acted upon by branch pipes 13, 14 from fire-fighting water tanks 15, 16.
  • the extinguishing water tanks 15, 16 are arranged above the hood 5 next to the chimney 17 adjoining it. They are fed with fresh water from a common line 18 via branch lines 19, 20.
  • the shower generally designated 26 is always pressurized from the two elevated tanks 15, 1 6 with the same pressure.
  • Serve chnellschlußventile S which are schematically at 22 and 23 in Fig. 1 respectively rendered at the lower end of the down pipe 12 and at the lower end of the riser pipe 10.
  • a control element 24 is seated in the connecting pipe bend 11. This is a control flap which can change the flow cross-section and is adjustable with an electronic or electrical drive.
  • a maximum amount of fire-fighting water is created on the control flap 24 in a first phase of the fire-fighting process. This is shown schematically by the height of the jets emerging from the upwardly directed nozzles 7 at 30 in FIGS. 1 and 2. This phase lasts about 20 seconds.
  • the flap position is then changed with the electric adjustment device so that in a second phase significantly less extinguishing water escapes, which is shown by the height of the nozzle jets at 31 in FIG. 1.
  • the system is designed as follows: Water supply before entering the extinguishing tower Extinguishing spray 8 pipe strings with 1 "pipe outlets directed upwards.
  • the emission value must be less than 100 g / t coke.
