Definitions

  • the present invention relates to a heat exchanger for use in coal hydrogenation plants at pressures from 200 to 700 bar and temperatures from 100 to 500 o C with a tube bundle arranged in a closed pressure vessel with tube-side inlet and outlet nozzles for the coal slurry and / or cycle gas, with shell-side Inlet and outlet nozzle for the heat-emitting circulating gas, in which the inner tubes are arranged between hoods closed by tube plates, and the hoods are connected by hood nozzles to the tube-side inlet and outlet nozzles for the pulp and / or the circulating gas.
  • the inner tubes have an outer diameter of 23 mm and an inner diameter of 14 mm. Under these conditions, it is possible to accommodate between 200 to 300 inner tubes arranged parallel to a tube bundle in a pressure vessel.
  • the hoods in the known designs are conical, the difference in thermal expansion between the tube bundle and the pressure vessel is absorbed by a stuffing box.
  • the known design has several disadvantages. For example, the conical hoods take up even more dead space with larger diameters than with diameters that were customary in the past.
  • the coal slurry and the cycle gas, which are guided around the pipes in the known constructions, can be of diameters. Do not distribute larger than 600 mm evenly over the entire cross-section of the jacket space.
  • baffles when driving with pulp and circulating gas around the pipes: this is disadvantageous in two respects.
  • the heat transfer coefficient becomes smaller than that of one cross flow achieved by chicane, and on the other hand the stability of the inner tubes is jeopardized by vibrations, the risk of vibrations can only be partially contained by installing inner tubes with a wall thickness of 4.5 mm and an outer diameter of 23 mm. In addition, it cannot be avoided that leaks occur on the stuffing box.
  • the hood connections are connected to the pipe-side inlet and outlet connections for the coal slurry and / or the cycle gas via weld seams.
  • a hood is arranged as an impact body at a distance of 500 to 1,000 mm from the jacket-side inlet connection.
  • the advantages achieved by the invention are, above all, that larger diameters can be used to save material. Damaged or clogged bundles can be installed and removed faster than with the previously known construction.
  • the arrangement of baffles on the jacket side increases the heat transfer and avoids the risk of vibrations of the inner tubes.
  • the installation of an expansion adapter prevents the pulp and / or circulating gas flowing on the pipe side from mixing with the circulating gas which emits heat and the jacket side.
  • FIG. 1 shows a longitudinal section through a heat exchanger according to the invention
  • FIG. 2 shows an enlarged partial view of this heat exchanger.
  • a tube bundle is arranged in a pressure vessel, consisting of a cylindrical jacket 1 with a flanged jacket hood 2, and a welded-on jacket 3, a tube bundle is arranged.
  • This tube bundle in turn consists of inner tubes 4, which are welded into tube plates 5 and 6.
  • the hoods 7 and 8 seal the coal pulp flowing on the pipe side and / or the circulating gas.
  • a hood connector 9 connects the hood 7 to the pipe-side outlet connector 11.
  • a hood connector 10 connects the hood 8 to the pipe-side inlet connector 12.
  • the welded connection between the hood connector 9, 10 and the outlet and inlet connector is shown in FIG.
  • the tube bundle contains baffle plates on the jacket side, which consist either of alternately arranged ring plates 13 and discs 14.
  • baffle plates which is not shown, but is used for horizontal heat exchangers, consists of circular sections.
  • the baffle plates are fastened with tie rods 15 to one of the two plates 5, 6.
  • the jacket 1 and the tube bundle have different wall temperatures during operation, and they also consist of materials with different coefficients of thermal expansion; therefore an expansion compensation intermediate piece 16 is installed in the hood connector 9 or 10.
  • the jacket-side inlet connector 17 is arranged so that the flow pulse is deflected with the hood 7.
  • Jacket-side inlet and outlet nozzles 18 can be rotated according to the requirements of the pipe routing as desired on a width circle of the spherical jacket hood.
