Definitions

  • the invention relates to a metallurgical melting unit according to the preamble of claim 1. It also relates to a pivotable nozzle or a swiveling burner according to the preamble of claim 14.
  • melter gasifiers as are known for example from DE-OS 28 43 303, i.e. for smelting units in which simultaneously hot reducing gas is generated during the melting process, cannot be used.
  • the aim of the invention is a metallurgical melting unit of the type mentioned, in which a pivotable nozzle or a pivotable burner can be inserted into the side wall of the melting unit in such a way that an essentially tight seal is ensured.
  • a pivotable nozzle or a pivotable burner can be inserted into the side wall of the melting unit in such a way that an essentially tight seal is ensured.
  • it is to be ensured that there is sufficient operational reliability and that it can be replaced easily.
  • the invention is explained in more detail by an embodiment with reference to a figure.
  • the figure shows the sectional view of a section from the side wall of a melter gasifier.
  • an opening 2 is provided above the bath level, through which an oxygen blowing nozzle 3 opens into the melter gasifier in order to melt with the coal present in the melter gasifier required heat and on the other hand to produce reducing gas.
  • the nozzle 3 comprises in a coaxial arrangement three tubes 4, 5 and 6, whereby a central channel and two ring channels are formed, as well as a head part 12 connecting the central tube 4 with the outer tube 6.
  • the central channel is connected to the central tube 4 attached gas inlet 7, the process gas, in the present case oxygen-containing gas, supplied, the ring channels are intended for liquid cooling of the nozzle.
  • the nozzle 3 is dome-shaped in the area of the passage through the side wall 1 of the melting unit.
  • the head part 12 is expanded in the form of a spherical cap 13 and this is resiliently clamped between two ring seats 14 and 15.
  • the first ring seat 14 is anchored in the side wall 1 of the melting unit and lies on the side of the curved surface of the cap 13 facing the nozzle tip 9, the second ring seat 15 has a position coaxial with the first ring seat 14 and lies on the side facing away from the nozzle tip 9 Side of the curved surface of the cap 13 and is pressed by spring force in the direction of the first ring seat 14.
  • This is an elastic clamping of the calotte ge give, which at the same time ensures a separation of the gas atmosphere inside the melting unit from the outside atmosphere through the first ring seat 14.
  • the gas-tight seal can be improved by an annular gas seal 16, which bears against the curved surface of the spherical cap in the region of its apex plane 17. The seal at this point is less thermally and mechanically stressed compared to the ring seat 14 and thus ensures a permanent gas-tight seal.
  • the first ring seat 14 is preferably designed as a liquid-cooled hollow ring 18.
  • the hollow ring 18 is part of a first conical tube section 19 which, in addition to the ring channel 20 of the hollow ring 18, has a further ring channel 21 for a cooling liquid, separated by a wall 23.
  • the cooling liquid is guided through a tube 22 in the underside of the conical tube section 19 to the ring channel 20, which has a partition wall (not shown) in addition to the entry point into this channel, runs in the ring channel 20 to a connection point located on the other side of the partition wall in the annular channel 21 and leaves it via a tube 34 in the upper part of the conical tube section 19th
  • the first conical tube section 19, which carries the first ring seat 14, is made of copper with regard to good thermal conductivity, as is the tip of the nozzle, and is pressed into the conical seat of an annular flange 24 made of steel, which at several points along its circumference rests on a sheet metal jacket of the melting unit attached mounting flange 25 is attached.
  • Three bolts 26 attached to the circumference of the ring flange 24 also serve to press the conical pipe section 19 into the ring flange 24 Elongated holes, by means of which pressure bolts 28 can be pressed against the end face of the conical tube section 19 by means of wedges 27.
  • the second ring seat 15 is formed on a second conical tube section 29 which is fastened to the ring flange 24 by means of screws 30 via three fastening tabs 31 stiffened along the circumference.
  • a defined contact pressure is generated by compression springs 33 and hat-shaped pressure disks 32.
  • the compression spring 33 becomes effective and the ring seat 15 is pressed resiliently against the curved surface of the spherical cap 13.
  • the elastic seat can be selected so that the angle can be continuously adjusted. If this is not necessary, the screws 30 can be tightened after the optimum angle has been set and the spherical cap can thus be firmly clamped.
  • the spherical cap is spherical. It is essential to the calotte design that the ring seat 14, possibly in conjunction with the annular gas seal 16, always ensures the gas closure required for the special case.
