Definitions

  • the invention relates to a device for cooling a synthesis gas generated in a gasification reactor with the aid of a quench cooler according to the preamble of claim 1.
  • a known quench cooler (DE-C-2 940 933) the inner jacket is provided with trickle cooling.
  • the application of a water film on the surface of the inner jacket is difficult, since there is a risk that the water to be applied evaporates on the hot surface and thus the water film tears open.
  • the gas generated in the gasification reactor is passed through the water sump, where it is cooled, saturated with water and freed from liquid slag and fly ash.
  • a disadvantage of such quench cooling is that the water from the water sump also absorbs the halogen components of the synthesis gas and is heated by the gas. The water must therefore be subjected to treatment and cooling after the solids have been separated off.
  • the gas entrains water droplets in which fine dust particles are suspended when it exits the water sump. These dust particles can bake on the wall of the cooler and in the subsequent pipes and lead to blockages.
  • the invention has for its object to carry out the cooling of the synthesis gas in the generic device in such a way that the water sump remains free of halogen components and caking of dust is avoided.
  • the water vapor content in the synthesis gas is adjusted by spraying water into the gas stream and not when it passes through the water sump.
  • the surface temperature on the cooled inner jacket becomes approximately the same in normal operation Gasification operating pressure corresponding boiling temperature. The surface temperature is thus far above the saturation temperature corresponding to the water vapor pressure of the synthesis gas, so that undershoots on the inner jacket are reliably avoided.
  • the spray nozzles are arranged, the intermediate section between the reactor outlet and the inner jacket ensures that the reactor outlet is kept warm, so that the reactor outlet is not blocked by solidification of the liquid slag outflow.
  • a quench cooler which contains an outer pressure jacket 1, is flanged to the outlet of a pressure gasification reactor, not shown.
  • the gas inlet 2 of the quench cooler is lined fireproof and has the same diameter as the outlet of the gasification reactor.
  • An intermediate section 3 of enlarged diameter adjoins the gas inlet 2. The height of the intermediate section 3 corresponds to approximately half to a simple value of its diameter.
  • the gas inlet 2 and the intermediate section 3 are provided with refractory heat insulation.
  • the lower part of the inner jacket 5 receives a water sump 6, which is connected to an outlet nozzle 7 at the lower end of the pressure jacket 1.
  • the water sump 6 serves to quench the liquid slag contained in the synthesis gas.
  • the quenched slag is withdrawn from the outlet nozzle 7 together with the water from the water sump 6.
  • one or more gas outlet connections 8 are provided, which are passed through the inner jacket 5 and the pressure jacket 1.
  • guide surfaces 9 are arranged obliquely downwards in the form of a funnel and are led out of the course of the inner casing 5.
  • the lower edges of the guide surfaces 9 project into the interior of the inner casing 5 and are supported on the inner casing 5 by means of pipes 10.
  • the gas flowing through the inner jacket 5 is deflected in this way to improve dust separation before it exits through the gas outlet connection 8.
  • the inner jacket 5 consists of a steel wall, which is provided on the back with an open, pressure-free relative to the process pressure evaporative cooling.
  • the pressure jacket 1 is provided in the lower part with a nozzle 11 which opens into the annular space 4.
  • Treated feed water is fed into the annular space 4 through the nozzle 11.
  • a chamber 12 is formed at the upper end of the annular space 4.
  • Downpipes 13 are arranged in the annular space 4 and are welded into a perforated plate 14. The downpipes 13 are passed through the inner jacket 5 with the lower ends below the level of the gas outlet connection 8 and connect the chamber 12 to the interior of the inner jacket 5, so that there is pressure compensation.
  • the lower ends of the downpipes 13 can end above the water sump 6 or can dip into the water sump 6.
  • the water volume within the annular space 4 is selected so large that in the event of any malfunctions in the quench system over a certain time, which is sufficient to take countermeasures, the entire residual and storage heat accumulated can be dissipated through the open evaporation system. Via the downpipes 13, the water fed continuously through the nozzle 11 during operation and the accumulated saturated steam are passed into the water sump 6.
  • Spray nozzles 15 protrude into the interior of the inner jacket 5.
  • the spray nozzles 15 are installed in cooled lances 16, which are interchangeably passed through the pressure jacket 1 and the inner jacket 5.
  • the spray nozzles 15 can be aligned both axially and radially with respect to the lance 16 or can be inclined downwards.
  • the lances 16 can be horizontal or obliquely downwards directional installed in the quench cooler. A first row of such lances 16 is arranged immediately below the intermediate section 3. Additional lances can be provided below this upper row of lances 16.
  • the front edges of the lances 16 lie on a pitch circle, the diameter of which is larger than the diameter of the intermediate section 3. In this way, the lances 16 are protected against slag flowing off.
  • the intermediate section 3 serves to ensure that the cooled synthesis gas does not come into contact with the edge of the gas inlet 2 by an internal backflow and would cool it, so that freezing of the slag flowing away, which would lead to a blockage of the gas inlet 2, is avoided becomes.
  • the amount of water added via the spray nozzles 15 is dimensioned such that the water evaporates almost completely and the synthesis gas is cooled to about 300 to 600 degrees C. when it exits through the gas outlet connection 8. At this temperature, the water vapor contained in the synthesis gas does not yet condense out, so that no significant amounts of halogens can get into the water of the water sump 6. The water sump does not heat up, which makes handling of the sump contents easier when discharging the quenched slag.
  • the cooled gas is optionally fed to a further processing system after further cooling in a radiation or convection cooler via a gas scrubber.
  • the inner jacket 5 is designed as a gas-tight tube wall.
  • the tube wall also forms the intermediate section 3.
  • the tubes are laid in a spiral in the tube wall and water is applied to them via tubes 17.
  • the spray nozzles 15 are integrated into the tube wall of the inner jacket 5.
  • the annular space between the inner jacket 5 and the pressure jacket 1 can also be filled with thermal insulation 18. Cooling tubes 19 are guided through this thermal insulation 18.
