Abstract:
A packing unit for liquid-gas contact apparatus, comprising:a first plurality of loops arranged about an axis, each loop of said first plurality being at a first angle with respect to a predetermined reference, said loops of said first plurality each having a top part and a bottom part, each loop of said first plurality having an interior point closer to said axis and connecting said top part of said loop with said bottom part of said loop, each loop of said first plurality having an exterior point farther from said axis and connecting said top part of said loop with said bottom part of said loop, each loop of said first plurality having a plurality of protuberances, a said top part of a said loop being offset from a said bottom part of said loop; a second plurality of loops arranged about said axis, each loop of said second plurality being at a second angle with respect to said predetermined reference, said second angle being the opposite of said first angle, each loop of said second plurality having an interior point closer to said axis and connecting said top part of said loop with said bottom part of said loop, each loop of said second plurality having an exterior point farther from said axis and connecting said top part of said loop with said bottom part of said loop, each loop of said second plurality having a plurality of protuberances, said loops of said second plurality each having a top part and a bottom part, a said top part of a said loop being offset from a said bottom part of said loop; said first loops and said second loops alternating; an interior support comprising a central area, said central area being a disk centered on said axis, a plurality of radial arms, a plurality of segments, and a plurality of protuberances, said radial arms being connected to and extending radially outward from said central area, each said segment connecting an interior point of a loop of said first plurality of loops to an interior point of a loop of said second plurality of loops, said protuberances being parallel to said axis and extending from predetermined ones of said segment, said interior support maintaining said loops of said first plurality of loops at said first angle and said loops of said second plurality of loops at said second angle; an external ring for connecting said exterior points of said loops of said first plurality and said exterior points of said loops of said second plurality; a first plurality of ribs, each rib of said first plurality of ribs connecting a said top part of a loop of said first plurality of loops to a said bottom part of said loop of said first plurality; a second plurality of ribs, each rib of said second plurality of ribs connecting a said top part of a loop of said second plurality of loops to a said bottom part of said loop of said second plurality; a plurality of cross bridges, each said cross bridge extending from and connecting a said loop of said first plurality to an adjacent loop of said second plurality, each said loop of said first plurality being connected to two said cross bridges, both of said cross bridges being connected to said adjacent loop of said second plurality; and a protuberance extending from each said cross bridge.
