Definitions

  • a packing unit comprising a stack of alternate flat and corrugated sheets of rigid thermoplastic organic polymeric material held together and arranged such that points or lines of contact of a corrugated sheet with one side of a fiat sheet are co-linear with the points or lines of contact with that flat sheet of the corrugated sheet on the other side of that same flat sheet.
  • I provide packings comprising at least one unit having the structure which comprises a rigid stack of alternate fiat and corrugated sheets held together such that rigidity is provided by the lines or points of attachment of one corrugated sheet with a flat sheet which correspond with the lines of attachment or at least some of the points of attachment of that same flat sheet to the next adjacent corrugated sheet, each corrugation being displaced laterally in the plane of the sheet to follow a curved path over a minor part of its length such that from the point of entry, as herein- I after defined, to the end of said displacement, a straight line passage through the corrugation is prevented by the curvature of the corrugation.
  • each corrugation of said corrugated sheets is displaced laterally in the plane of the sheet to follow a curved path over a minor part of the length of the corrugation near the point of entry, as here- .in after defined, such that, either the corrugation following said curved path is displaced wholly to one side of or the corrugation following said curved path is initially displaced to one side of said main axis and is thereafter displaced to the other side of said main axis, the maximum lateral separation between points on the apex of the corrugattion lying on each side of the main axis being at 1 least equal to the width of the corrugation, the remainder of the corrugation beyond the initial curved path following either a straight line or a gentle curve.
  • point of entry I mean the end of the corrugation at which liquid normally enters the packing.
  • main axis of the corrugation I mean the line of the apex of the corrugation if it followed a straight path from the point of entry.
  • width of corrugation I mean the distance between the apices of two adjacent corrugations.
  • rugated sheets having corrugations which are displaced equally about the main axis since in this case approximately equal amounts of liquid will contact each surface of the corrugated sheet, thereby providing a large surface of the liquid to the elfec-t of the air current.
  • FIGURE 1 is an elevation of one corrugation of a corrugated sheet of the first em bodiment.
  • 'FIGURE 2 is an elevation of one corrugation of a corrugated sheet of the second embodiment.
  • FIGURE 3 is an elevation of one corrugation of a corrugated sheet of the third embodiment.
  • I .FIGURE 4 is a perspective view of a packing of the third embodiment in which the corrugated sheets have corrugations similar to those in FIGURE 3.
  • FIGURE 5 is a perspective view of a packing similar to that shown in FIGURE 4 except that the corrugations of one corrugated sheet curve in the opposite direction from the corrugations of the next corrugated sheet.
  • FIGURE 6 is a vertical section-a1 vie-w of a gas-liquid contact apparatus containing a plurality of the packing units of the present invention.
  • FIGURES 1 to 3 corrugations are shown each one having two sides 1, 2 and an apex 3.
  • the two sides form a V at the apex with an included angle of 60.
  • the liquid normally enters the corrugation at 4 in the direction of the arrow, and so 4 represents the point of entry. If the corrugation was not curved, the apex 3 would lie along the line 5 in each case and so line 5 is the main axis of the corrugation.
  • the corrugation has a curved portion 6 and a linear portion 7. This linear portion is displaced from the main axis 5 by the distance A.
  • this distance A is made equal to the width of the corrugation which was hereinbefore defined as the distance between the apices of adjacent corrugations.
  • This width of the corrugation may also be defined as that distance represented by distance B in FIGURE 1.
  • distance A equals distance B in the embodiments shown in FIGURE 1, but in other embodiments the distance A may be greater than distance B.
  • liquid entering the V at the point of entry 4 in the direction of the arrow between points 12 and 13 will contact the surface 2 of the corrugation between points 12 and 14.
  • Liquid entering the V between points 13 and 15 will contact surface 1 of the corrugation between points 16 and 17. If equal distribution of the liquid over the point of entry 4 is assumed, then equal distribution of the liquid on to surface 1 and 2 will result.
  • FIGURE 3 the remaining portion 18 of the corrugation is gently curved until the exit point 19 is lined up with the point of entry 4.
  • the packings may be installed directly above one another as opposed to the necessary displacement between layers when packings using the form of corrugation of FIGURES l and 2 are used. Furthermore, since the entry and exit points are lined up the packing can stand stably without the need for supporting members.
  • the main curved portions of the corrugation should only occupy a small portion of the length of the corrugation in order that the greatest possible area of the surface of the corrugation may be used for cooling and the like.
  • FIGURE 4 three layers of corrugated sheets 20, 21, 22 are shown interleaved with three flat sheets 23, 24, 25.
  • the corrugations of the corrugated sheets have the form of the corrugation shown in FIGURE 3.
  • the laterally protruding parts 26, 27, 28 and 29 of the corrugated sheets fit into the corresponding free spaces in adjacent packings.
  • the packings are made up from alternate corrugated and flat sheets.
  • Alternate corrugated sheets may be arranged in such a way that either the curved portions of the corrugations all curve in the same direction as in FIGURE 4 or the curved portions of one corrugated sheet curve in the opposite direction to the curved portions of the corrugated sheet on the other side of that flat sheet. This latter arrangement is shown in FIGURE 5 wherein two corrugated sheets are shown fixed on opposite sides of a flat sheet. Only one corrugation of each sheet is shown.
  • One corrugation 30 of a corrugated sheet is shown fixed to the front face 31 of a flat sheet 32.
  • the corrugation has the form shown in FIGURE 3.
  • a second corrugated sheet is fixed to the rear surface 33 of the sheet 32.
  • One corrugation 34 of this second corrugated sheet is shown.
  • This second corrugation 34 also has the same form as that shown in FIGURE 3.
  • the points of entry and exit of the two corrugations 30, 34 are aligned and the three sheets are fastened together by press studs and sockets preformed in the sheets at the points encircled and numbered 35. It will be noticed that each of these points corresponds to the points where, if the fiat sheet were omitted, the two corrugations would contact each other.
  • the points encircled and numbered 36 correspond to points where the corrugations shown are fastened to the corrugations forming the remainder of the two c-orrugated sheets.
  • FIGURE 6 illustrates schematically a gas-liquid contact apparatus, such as a cooling tower, comprising a vertical hollow tower structure 50 containing a plurality of the packing units 52 of the present invention suitably supported within the tower structure.
  • a gas-liquid contact apparatus such as a cooling tower
  • liquid enters the top of the tower structure and flows downwardly over the surfaces of the packing units 52 while cooling gas passes upwardly through the passages in the units 52.
  • each packing When packings are made from sheets having the corrugations hereinbefore described, each packing has a low resistance to air pressure blowing in the direction opposite to the flow of liquid.
  • the flat and corrugated sheets may be made from any rigid material such as metals, asbestos cement or rigid thermoplastic materials.
  • organic thermoplastic materials include polyvinyl chloride, polymethyl rnethacrylate, polypropylene, high density polythene, 'polyvinylidene chloride, copolymers of vinyl chloride and vinyl acetate, polystyrene, oxymethylene polymers, rubber/resin compositions (e.g. mixtures of butadiene/acrylonitrile copolymer rubbers and styrene/ acrylonitrile resins).
  • the packings of my invention may be used for cooling many liquids and are particularly useful for corrosive liquids, the material of the packings being selected for resistance to corrosion from the liquids that will be encountered.
  • a gas-liquid contact unit for apparatus in which a gas stream contacts a film of liquid flowing as a film over the surfaces of a contact unit, said unit comprising:
  • each corrugated sheet having apices forming lines of contact with the flat sheets; all the corrugated sheets defining with all the flat sheets a plurality of passages all of which extend from one common face of the stack to the opposite face;
  • Gas-liquid contact apparatus for contacting a gas stream with a film of liquid flowing over contact surfaces within the apparatus, said apparatus including at least one contact unit as claimed in claim 1.
  • a packing unit is in claim 1 wherein said corrugations are generally V-shaped.
  • each of said corrugations in the region of said curved path has a main axis from which the apex of the respective corrugation is displaced, the maximum displacement being at least equal to the distance between apices of two adjacent colrugations.
