Definitions
- the invention relates to a device for cooling, in particular, S0 2- containing gases, consisting essentially of an externally cooled bundle of extruded lead pipes arranged in parallel at the ends and fastened in tube sheets with internal longitudinal ribs, a housing with supply and discharge lines for a coolant and diffuser-like connecting channels for the gas flow.
- the invention has for its object to show a way to improve the gas cooler described above, wherein 'on the one hand noticeable weight savings achieved, but on the other hand, the functionality of the gas cooler is not affected during the specified life.
- the post-deformation can expediently consist in that the indentations are dome-shaped.
- the indentations of the lead pipes can be designed as annularly encircling depressions.
- FIG. 1 shows a section and cross section of a lead pipe 1, in which the post-forming was carried out by means of steel balls in the form of displacements offset by 120 ° C., in which dome-shaped indentations 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 through ring shaped constrictions 5 was deformed.
- the lead pipe viewed in longitudinal section, receives a plurality of successive barrel-shaped regions 6.
- FIG. 3 shows the results of creep rupture tests in which various pipe samples Nos. 1 to 3 were subjected to an external water pressure in the test apparatus.
- 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. Thereafter, the pressure was increased by approximately 0.5 bar at approximately constant intervals, the non-deformed tube No. 3 being compressed at a pressure of 4 bar after 1150 hours until the inner ribs abutted against one another.
- Tube sample No. 1 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.
