Definitions

  • the invention relates to a cooling device (Quenche), in which hot corrosive combustion gases are cooled by injecting liquid, as z. B. arise from the combustion of gaseous and / or liquid chlorine-containing residues or chlorinated hydrocarbons.
  • the quench In the upper part, into which the hot combustion gases with a temperature of up to 1400 ° C enter, the quench is primarily thermally stressed.
  • the steel jacket must be protected against overheating by appropriate lining (hot zone).
  • the steel jacket After quenching the exhaust gases to a temperature below 100 ° C using water or aqueous hydrochloric acid and partially absorbing the corrosive constituents of the exhaust gas in the quench liquid, the steel jacket is mainly to be protected against corrosion (wet zone).
  • the problem with the quench described is, however, that the hot zone and the wet zone cannot be clearly distinguished from one another in practice.
  • the area where the hot exhaust gases and the injection liquid meet is characterized by great turbulence, which leads to fluid being swirled far up into the hot zone, while on the other hand the wall of the wet zone, especially in the area of the nozzles, is not sufficient everywhere is wetted and cooled so that local overheating occurs.
  • thermal insulation bricks are not corrosion-resistant and the corrosion protection lining made of rubber and ceramic plates is heat-resistant. h, the plates themselves are not damaged, but are unable to keep the heat away from hard rubber.
  • DE-PS-2 621 718 C3 describes a quench in which the entire steel jacket is lined with corrosion resistance and this heat-sensitive lining is protected in the upper hot zone by walling in thermal insulation bricks. There is no middle transition zone, in which there is protection against heat and corrosion at the same time. The thermal insulation bricks are not protected against corrosion and the anti-corrosion lining of the lower wet zone is not protected against overheating in the upper area.
  • the outer steel jacket of the Quenche consists of 2 steel cylinders of different diameters (1, 2), which are welded together with a cone (3) and closed at the top and bottom by curved floors (4, 5).
  • the diameter of the upper cylindrical part (1) of the steel jacket is so much larger than is necessary to be able to accommodate the additional lining layers (6, 7) for the upper hot zone, so that before and after the application of the last inner corrosion-resistant lining ( 8) results in a cylindrical interior of the same diameter.
  • the central gas inlet connection (9) At the top of the steel tank is the central gas inlet connection (9), through which the combustion gases are introduced into the quench.
  • the side gas outlet connection (10) In the lower third, close to the lower curved bottom, is the side gas outlet connection (10) through which the quench liquid runs out at the same time.
  • the lowest central nozzle (11) is used for emptying and cleaning purposes during downtimes. However, it can also be used for the separate removal of the quench liquid during operation.
  • Around the gas inlet connector (9) at least 6 connectors (13) for the nozzle assemblies are arranged at the same distance so that the axes of the nozzle assemblies form an angle of approximately 30 ° with the axis of the gas inlet connector (9).
  • In the upper area of the wet part (cylindrical part 2) At least 3 nozzles (14) for the nozzle sticks of the second level are attached, pointing slightly downwards.
  • a connector (15) for receiving a quench nozzle is placed on the gas outlet connector (10) as additional security for the connected lines and devices, which are usually made of plastic.
  • the entire inner surface of the steel container including all sockets up to the sealing surfaces of the flanges is rubber-coated (16).
  • the rubber coating is first clad with acid-resistant (6), then with heat-insulating (7) ceramic plates or stones.
  • the sockets (10 - 15) are lined with the acid-resistant plates, the gas inlet socket (9) is lined with acid-resistant and heat-insulating plates.
  • the interior prepared in this way which now consists of a cylinder of the same diameter as well as the upper and lower curved floor, is lined with a total of 1 - 2 layers of ceramic (8) in a corrosion-resistant manner.
  • the temperature of the rubber coating and the outlet temperature of the gas are monitored in the usual way with temperature sensors.
  • the invention relates to a cooling device for quenching hot, highly corrosive, chlorine and hydrogen chloride-containing combustion gases, consisting of an elongated cylindrical standing container provided at the top and bottom, each with a curved bottom, a central connector for the gas supply at the upper end of the steel container, several in the upper One-third of the steel container equidistantly arranged in a horizontal plane inclined nozzle for receiving nozzles for atomizing circulating quench liquid, a side nozzle in the lower third of the steel container, above the curved bottom, as an outlet for the quenched combustion gases and quench liquid, a central nozzle at the lower end of the steel container for cleaning purposes and as a drain for quenching liquid, an acid-resistant hard rubber lining on the inner surfaces of the steel container and all Socket, an acid-resistant ceramic lining on the acid-resistant hard rubber layer and a fire-resistant lining made of heat insulating stones on the acid-resistant lining in the upper area of the steel container, which is characterized in
