Definitions

  • the inventiom relates "to' a'rectifying column containing plates being arranged in a distance of less than 150 ms. one from another.
  • the distances between the several plates had necessarily to be about 150 mms. or more. Therefore, the problem arose to reduce the said distances by special arrangements and to increase at the same time the velocity of the vapor in such a manner that means, alternating with a ring-shaped plate.
  • ranged plane-like means partly forming channels so that the vapor streaming from one plate to the next following plate must repeatedly change its direction, preferably by more than 90, the idea playing a decisive part that, owing to their weight, the particles of the liquid carried along cannot by far follow the compulsory change of the direction so rapidly as the particles of vapor and, consequently, must be separated by impinging upon the guide planes.
  • the guide planes which are arranged between the 7 different plates and which serve as arresters for the output of the rectifying column was malnthe particles of liquid .carried along and as a means for'repeatedly influencing the direction of the flow of vapor are arranged so that the particles of liquid not volatilized are returned in their entirety to the plate from which they were drawnupward.
  • Figs. 1 and 2 show the arrangement according to this invention on staggered plates known per se.
  • a hood b with arrester planes in and a conical sheet 0 also serving as arrester.
  • the lower border of this sheet is only loosely placed or attached only at some spots so that the liquid may pass underneath the border of said sheet.
  • arrester planes e and f are arranged above the circular plate, dand g and h are the places where the liquid to be returned flows, whereas It means a partition wall and t is one of the guide planes arranged on the plate a and fastenedto a bubble cap, k and i being the parts which serve to regulate the direction of the particles of liquid.
  • the rectifying column works, for instance at two plates. as follows:
  • Fig. 1 is a sectional elevation
  • Fig. 2 is a sectional plan view of a rectifying cclumn equipped with plates in accordance with the present invention.
