  • Two blocks are at a distance from each other Sheet width 60 opposite, so that the blocks 70 form a cross in plan view, in whose center a square with the side length of the sheet width 60 remains free.
  • each storage container 71 is connected to two blocks 70.
  • the lowest circulation sections 7f are on the other hand, with liquid from the bottom of the column or the container in which the bath condenser is fed.
  • the associated separating space 72 has approximately the shape of a in cross section Triangle, the legs of the outside of the L-shaped Liquid reservoir 71 are formed and the base of one side of the Octagon is formed.
  • the advantage of this arrangement is the good utilization of the circular cross-section with little construction effort.
  • the liquid is transferred from one circulation section 7 to the one below Circulation section 7 again passed through an overflow pipe 30.
  • the gap between the octagonal body and the cylindrical wall of the container 50, in to which the bath condenser is located serves as a gas discharge line 18.
