Definitions

  • the invention relates to a device for cooling, in particular, S02-containing gases, consisting essentially of an externally cooled bundle of lead pipes arranged in parallel and fastened at the end in tube plates with internal longitudinal ribs, a housing with supply and discharge lines for a coolant and diffuser-type connecting channels for the gas flow.
  • a device for cooling in particular, S02-containing gases, consisting essentially of an externally cooled bundle of lead pipes arranged in parallel and fastened at the end in tube plates with internal longitudinal ribs, a housing with supply and discharge lines for a coolant and diffuser-type connecting channels for the gas flow.
  • S02-containing gases consisting essentially of an externally cooled bundle of lead pipes arranged in parallel and fastened at the end in tube plates with internal longitudinal ribs, a housing with supply and discharge lines for a coolant and diffuser-type connecting channels for the gas flow.
  • the invention has for its object to show a way to improve the gas cooler described above, on the one hand noticeable weight savings achieved, but on the other hand the functionality of the gas cooler is not impaired during the specified life.
  • the post-forming can expediently consist in that dome-shaped indentations are attached to the tube from the outside.
  • annular circumferential depressions can also be pressed into the tube from the outside. The same advantages can also be achieved if the lead pipes are pressed into a shaping one spanmunag are partially expanded from the inside.
  • FIG. 1 a section of a lead pipe 1 is shown in view and cross section, in which the post-deformation was carried out by means of steel balls in the form of impressions arranged offset by 120 ° C., in which dome-shaped depressions 2 are formed. Lines 3 mark the boundary of the forming areas.
  • Figure 2 shows a view and cross section of a lead pipe section 4, which was post-deformed by annular constrictions 5.
  • the lead pipe viewed in longitudinal section, receives a plurality of successive barrel-shaped regions 6.
  • FIG. 3 shows the results of creep tests in which various pipe samples in the test apparatus were subjected to an external water pressure.
  • the service life in hours is shown on the abscissa and the pressure applied in bar on the ordinate.
  • the samples were initially subjected to an external pressure of 2.5 bar for 750 hours.
  • the pressure was then increased by approximately 0.5 bar at approximately constant intervals, the pipe, which had not been deformed, being compressed at a pressure of 4 bar after 1150 hours until the inner ribs abutted against one another.
  • the tube sample with ball indentations according to FIG. 1 only collapsed at 4.5 bar after 1330 hours. It should therefore be noted that a simple improvement of the reshaping can significantly improve the service life or the possibility of pressure loads.
