Definitions

  • the heat-exchange elements of the lower annulus can be more steeply inclined than those of the upper annulus.
  • the operation of the tower can be regulated by accommodating blocking arrangements, such as valves and the like, in the connecting pipes.
  • the heatexchange elements of either or both of the annuli can be provided with shutters which are known per se from the art to vary the air flow.
  • shutters which are known per se from the art to vary the air flow.
  • the condensate collecting tubes 17 of the adjacent heat-exchange elements 5 of any two consecutive assemblies 6 extend in horizontal direction towards axis 8 in a V-shaped manner, and in the region between the upper and lower annuli A and B they join and here constitute the upper ends 18 of the assemblies 7 of the lower annulus B.
  • assemblies 7 are so constructed that approximately three-fifths of the heat-exchange elements 5 forming the assemblies 7 act as condensers, and the remaining two-fifths are constituted by the heatexchange elements 5" which act as dephlegmators.
  • the operation of condensers and dephlegmators is well known in the art and requires no discussion. E.g. see DT-PS l,()66,596 and DT-AS 1,451,131, which shows the operation of condensers and dephlegmators.
  • the heat-exchange elements 5' are located in the outer regions 19 of the assemblies 7, whereas the heatexchange elements 5" are located in the inner regions 20 of the assemblies 7.
