Definitions

  • the invention relates to a device for cooling a hot product gas which contains sticky particles which lose their tackiness on cooling, consisting of a tubular zone in which the product gas is cooled directly by cooling gas and a gas wall being formed in the wall of the tubular zone, which prevents contact of the product gas with the wall.
  • Such a device is known from US-PS-2 971 830.
  • a particle-free protective gas is fed in near the inlet of the tubular zone in such a way that a protective gas layer is formed on the wall of this zone, which prevents contact of the wall with the hot product gas, the protective gas being at the same time a cooling gas.
  • the cooling gas is fed in through an annular insert with a tangentially directed speed component, and through inlets arranged in the radial direction, which lie above the outlets in the annular zone.
  • the outlets are arranged at equal intervals around the circumference of the tubular insert somewhat above its lower end, so that there is an annular region not acted upon by the cooling gas in the direction of flow at the beginning of the critical zone mentioned.
  • the cooling gas is not only blown in countercurrent to the product gas, but is directed around the lower end of an insert, it flows seamlessly through the tubular zone from the lowest end of the insert over the entire endangered length of the wall of the tubular zone.
  • This shows a wall section 1 of a carburetor, in which the product gas is generated.
  • the wall section 1 merges into an outlet connection 2, which forms the tubular zone through which the product gas flows upward out of the gasifier.
  • the product gas entrains particulate substances which are sticky due to the high temperature of the product gas and which only lose their tack after the product gas has cooled.
  • the temperature of the product gas is still so high that there is a risk that the entrained particles, when they hit a solid wall, get caught on it.
  • annular insert 3 within the outlet nozzle 2, which forms a gap 4 between itself and the inner wall of the outlet nozzle 2.
  • this gap 4 is equidistantly distributed over the circumference of the outlet nozzle 2, one or more inlet opening (s) 5 for a cooling gas, which at the same time form a contact between the product gas and the inner wall of the outlet nozzle 2 or the insert 3 preventing gas wall is used.
  • the inlet opening (s) 5 can be connected, for example, to a ring line which is guided around the outlet connection 2.
  • the cooling gas flowing down through the gap 4 prevents the product gas from entering the gap 4 and thus clogging of this gap by the particles contained in the product gas.
  • the cooling gas is directed around the lower end of the insert 3 by the product gas flowing upwards, so that it flows upwards again on the inner surface of the insert 3 parallel to the latter. It forms a continuous gas wall, which prevents the product gas from touching the insert 3.
  • the sticky particles entrained in the product gas can therefore not reach the inner wall of the insert 3 and attach to it.
  • the cooling gas simultaneously causes cooling of the product gas during the passage through the insert 3, so that the product gas has cooled down at the upper outlet of the insert 3 to such an extent that the particles in it have lost their stickiness.
  • This cooling effect is supported in that the insert 3 itself is cooled. It contains for this purpose, for example, cooling channels running in its interior through which water or another suitable cooling medium flows.
