Definitions

  • the invention relates to columns of the stated kind in which the plates are formed in known manner so that in operation each of them carries a quantity of liquid up to a restricted depth, into and through which liquid gases or vapours rising from the underlying compartment penetrate through the plate perforations. bviously it is necessary to maintain a pressure gradient over each plate, by which the liquid carried on the plate is supported; and it is therefore necessary to prevent the ascending gases or vapours from llowing around the edge of the plate, for which reason such edge is sealed, Iby an asbestos packing ring or the like, with respect to the wall of the shell.
  • An object of the invention is to simplify and improve the connection or joint between the edges of the plates and the wall of the shell.
  • the edges of the plates are sealed against the wall of the shell by annular elements consisting entirely of metal which encircle the plates and bear elastically against the wall of the shell with a certain degree of pressure, the open expansion slots of these elements being narrower than the individual perorations in the plates.
  • said open expansion slots are arranged below the level of the perforations in the pertaining plate in such manner that a somewhat higher column of liquid extends over them than over the above-mentioned perforations; this measure reliably prevents the pressure difference or gradient necessary for proper operation of the plate from escaping through the expansion slots.
  • Fig. 1 is a partial sectional elevation of a cylindrical column with a sealing ring according to the invention.
  • Fig. 2' is a sectional elevation on a larger scale of the sealing region.
  • Fig. 3 is a plan View of the turnbuckle or tightening means of the sealing ring.
  • Fig. 4 is a perspective view of the ends of the ring foiming the expansion slot.
  • Fig. 5 is a sectional elevation of a modified form of construction of the sealing ring and plate edge.
  • the cylindrical shell 1 the axis of which'is indicated ⁇ by the lines x-y, contains tted plates 2 and 2a provided with a number of capped openings or periorations 3 and 3a for the ascending gases or vapours.
  • the liquid flows on to the plate 2 peripherally through the pipe 4, covers the plate up tothe level indicated by s-b and then flows down through the central overflow pipe 5 on to the plate 2a, whichbecomes covered with the liquid to the level c-d. From the plate 2a, the liquid ilows peripherally through the overow pipe 4a Vto the next subjacent plate (not shown) and so on.
  • the pipes i and 4a are immersed below the levels a-b and c-d; they each, therefore, form a liquid seal through which the gases or vapours ascending from the surface of the liquid, cannot pass. These latter, consequently, flow in the direction of the dotted arrows A through the openings 3 and 3a from below, into the liquid on the plates 2, 2a.
  • rings 6 and 6a The sealing of the plates 2, 2a round their outer edges is performed by rings 6 and 6a, the form of which is more clearly shown in Fig. 2.
  • Each ring is bent-up from a profile bar of inverted F cross-section, the vertical limb 7 of which is pressed rmly against the shell wall 1 while the two horizontal circular limbs 8 and 9 lie respectively below and above the pertaining plate 2 or 2a.
  • a turnbuckle is provided (Fig. 3) between the endsl of each ring 6 or 6a, the two lugs 10 and 11 of which turnbuckle are welded to the two ends of the ring and are pressed apart by two nuts 12, 13 on a screw spindle 14 in such manner that the ring is pressed radially against the shell wall 1.
  • each sealing ring may be a self-tightening sea-ling ring as shown in Fig. 5, consisting of a tightly-wound wire coil spring 15 the ends of which are joined to form a closed ring which is pressed from above into the space between the shell wall 1 and a downward-flanged rim 16 of the pertaining plate 2b.
  • the ring 6 or 6a may be made with only one horizontal limb 8 or 8a if the plate 2 or 2a is by anyA other means prevented from being lifted 01T its support as by pulsations inu the operation of the column; the ⁇ coil spring 15 can itself be replaced by a hanged metal' ring ⁇ made elastic ⁇ by radialV slits and thus ,bearing ⁇ elastic'ally against the shell; it is even possible to ange downthe edge of the plate itself, and slit it radially sothat the elastic, closely spaced tongues thus formed, ⁇ themselves act as sealing means.
  • the plate itself must be made of suitably thin and elastic "sheet metal and its central part then stitfened by ribs or ⁇ the like.
  • said horizontal flange supporting the periphery of said deck
  • said annular member comprising two parallel horizontal flanges, whereby said annular member has a ⁇ cross-section in the shape ofinverted F, the periphery of said ⁇ deck -being inserted into the space between the two horizontal llanges of said annular member.
  • a sealing means interposed between the periphery of the deck and the inner wall of the container, said means comprising an annular member having a vertical and at least one horizontal flange and being coaxially arranged within said cylindrical container, and a turn buckle on said means forcing the vertical llange of saidannular member'radially against the adjacent walls of said container, said horizontal flange supporting the periphery of ⁇ said deck, said ⁇ annular member being radially split, comprising two parallel horizontal llanges and having the form of an open ring having a cross-section of an inverted F, one of the two horizontal flanges of which lits below thedeck and the other flange lits above the deck, and both flanges overlap at the radial split of said ring.
