Definitions

  • the invention relates to a device for cooling hot, pressurized, dust-laden gases with the features of the preamble of claim 1.
  • the device is known from DE-OS 3 208 421 and is used to cool the gases leaving a gasification reactor.
  • the flat tube walls ensure intensive cooling of the gases.
  • the radiation cooler is followed by a separate convection cooler with bundle heating surfaces.
  • the invention has for its object to design the heating surfaces of the generic device so that a compact cooling device is created.
  • the tube bundle serving as a convection heating surface By arranging the tube bundle serving as a convection heating surface within the radiation cooler, the gas can be cooled in a short way.
  • the direct continuation of a flat tube wall in the tube bundle enables a compact design of the cooling device.
  • the cooler shown is used to cool hot, pressurized and dust-laden gases, especially those that are generated in a gasification reactor.
  • the cooler consists essentially of two components, namely a standing pressure vessel 1, which has the task of absorbing the pressure of the gas, for example from 20 to 25 bar, and of the internals which act as heat exchangers.
  • the internals are composed of an insert 2, flat tube walls 3 (bulkhead walls), a first tube bundle 4 and optionally a second tube bundle 5 or further tube bundles.
  • the pressure vessel 1 consists of several cylindrical segment rings welded together. It is closed by an upper and a lower cover 6, 7.
  • the upper cover 6 is provided with a gas inlet connection 8 and the lower cover with a gas outlet connection 9.
  • a screwable flange connection 10 is inserted in the upper part of the pressure vessel 1 in order to ensure easy opening of the pressure vessel 1.
  • the pressure vessel 1 can be parked with the help of claws.
  • the insert 2 is arranged at a distance from the inner wall of the pressure vessel 1 and is connected to the gas inlet connection 8 in such a way that the gas to be cooled which flows in flows through the insert 2 in the longitudinal direction.
  • the outlet end of the insert 2 is open so that a pressure equalization between the interior of the insert 2 and the annular space between the insert 2 and the pressure vessel 1 can take place.
  • the insert 2 is formed from gas-tight, welded, cooled pipes which are connected to an inlet header 11 located in the lower part and to an outlet header 12 located in the upper part.
  • the tubes of insert 2 are flowed through from bottom to top and connected as an evaporator.
  • the flat tube walls 3 are arranged within the insert 2 and run in the longitudinal direction of the pressure vessel 1 and parallel to one another.
  • the tubes 13, 14 of the tube walls 3 are connected to one another via flat iron and are each connected to an inlet header 16 and an outlet header 17.
  • the feed lines to the inlet manifolds 11, 16 of the tube walls 3 and the insert 2 are led through the annular space between the insert 2 and the pressure vessel 1.
  • the tube walls 3, like the insert 2, are connected as evaporators and flowed through from bottom to top.
  • the tubes of at least one of the tube walls 3, preferably the middle tube wall, are bent out to form the first tube bundle 4, which extends in several turns over the cross section of the insert 2.
  • the first tube bundle 4 is connected as an evaporator.
  • a pipe 14 is bent out of the plane of the pipe wall 3 from three neighboring pipes (FIG. 3).
  • alleys 18 are formed within the tube walls 3, through which the tubes of the tube bundle 4 are passed.
  • the tubes 13 are connected to one another on both sides of the lanes 18 by a web 19.
  • the tubes of the tube bundle 4 are passed through this web 19 and are thus carried.
  • the tubes of the tube bundle 4 can also be surrounded by a welded-on sleeve.
  • the tubes 13 of the tube walls 3 remaining on the wall plane on both sides of the middle tube wall 3 thus serve as support tubes, while the tubes 14 of these tube walls and the tubes 20 of the other tube walls are guided as loose tubes.
  • a second tube bundle 5 or further tube bundles can be provided within the insert 2.
  • the second tube bundle 5 can be connected as a superheater, feed water preheater or as an additional evaporator.
  • the second tube bundle 5 is guided through the tube walls 3 in the same way as the first tube bundle 4 and carried by these.
  • the second tube bundle 5 is at an step collector 21 and an outlet collector 22 connected.
  • the tubes of the middle tube wall 3 are alternately bent out to the right and left and serve to hold the collectors 21, 22.
  • the cooler shown in FIG. 3 has a gas inlet connection 8 connected to the lower cover 7 and a gas outlet connection 9 connected to the upper cover 6.
  • the tube bundle 4 has been moved into the upper part of the insert 2. Otherwise, this cooler corresponds to the cooler according to FIG. 1. In such a cooler, the incrustations removed from the tube walls 3 can be removed from the cooler in a simpler manner.
