  • Fig. 7 is a detail vertical sectional view on the line 7 of Fig. 6;
  • Fig. 1 is shown apport-ion of the vertower embodying the present invention.
  • This shell is providedwith manholes 11 arranged lin vertical rows, alternatemanholes being set at an angle to one another for the purpose hereinafter set forth.
  • manholes 11 are preferably of a size such that the sections forming the plates of the column may be inserted therethrough.
  • Typical plates of the column are shown in Figs. 4, 5 and 6.
  • the type of plate illustrated in Fig. 6 differs from those illustrated i'n Figs. 4 and 5 principally in that, in the former, fewer overflows for reflux are provided, these plates being intended for use in portions ofthe column where less overflow liquid is anticipated.
  • each ⁇ plate is made up of four sections, the
  • Each of the plate sections 13 and 13 is provided with a number of upwardly projecting nipples 15, preferably of substantially rectangular shape. These projecting nipples provide4 for the passage of gas from the vapor space below the plate sections to that above 1t, and each of the nipples is provided with a substantially rectangular bubble-cap 16, the lower edge of which is suitably serrated as at 16a.
  • the nipples 15 and'caps 16 may4 be so arranged as to provide aplurality of rows of bubble-caps substantially evenly spaced from one another, the rows extending substantially transversely across the plate and 13a are formed with upwardly projecting dams 17 and 17, so arranged that when the sections are properly; placed, a pool 18.
  • the pools 18 suitably include an area extending the width ofthe center sections, from which pools the overow from the next plate above is distributed ⁇ between the bubble-caps.
  • segmental sections 2,0 and 20 On opposite sides of the assembled center sections 13 and 13 areprovided the segmental sections 2,0 and 20, which may likewise be substantially mirror images of each other.
  • Theplate sections 20 and 20a are provided on the side forming the chord of the are with downwardly depending flanges 21, by which connection may be made with the flanges 14.- on the outer margins of the center plates.

  • bubble-caps 25 of the same type as the bubble-caps 16 or of generally similar type, likewise preferably arranged symmetrically with respect to a transverse median line through the assembled plates.
  • These bubblecaps are so disposed with reference to the pools A18 as to balile and subdivide the portion of thec'overflow streaming over the sides of 'thepools 18 into streams of substantially the same size as those formed by the bubble-caps 16.
  • -Deflectors 25 may likewise bevprovided to aid in an even distribution of the overflow.
  • angular lugs 28 are securedto the upwardly extending flanges 26 of the plate sections 20 and 20, and straps 29, suitably of angleiron, are extended transversely across the ltops ofthe assembled plates, these stra s passing, under the lugs 28. r They are hel in positionby any. suitable means, for example, the pins 30 passing through suitable openings in the lugs 28 and the ends of'A the straps 29.
  • each plate of the column is suitably arranged at an angle 'of approximately 909 with respect to those above and belowit.

  • the bubblecaps 25 and deflectors 25 balile and similarly distribute the flow of overflow liquid from the sides of the pools 18.
  • the liquid is caused to travel' in approximately uniform streams -around and between the bubble-caps to the central portionof the plate, there joining-the flowing to the oppositely disposed ovcrow pipes.
  • This course is indicated on Fig. fl ofthe drawings by arrows.
  • the depth of the stream of overflow liquid is greater toward the center of the'plate, and'decreases toward the outer plates.
  • the shimslb are inserted between twlower caps and straps 29.
  • FIGS. 2 and 3 show diagrammatically the relative arrangement withili the tower of successive plates, the parts shown diagrammatically being indicated by the same reference numerals as the corresponding Vparts in the more detailed drawings.
