Abstract
Abstract A packing material for liquid/gas contact reaction apparatus, in particular for gas purifying systems, which consists of a plurality of parallel rods arranged on a basket-shaped carrier and so dimensioned that it has an approximately spherical or spheroid form. The carrier consists preferably of parallel rings of staggered diameters. The packing material according to the invention has an extraordinarily high degree of efficiency and is very easy and relatively cheap to manufacture.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
139 words
A packing material unit for positioning in bulk or random relationship within a liquid-gas contact apparatus in order to enlarge the contacting surface of a liquid and a gas flowing through said apparatus, said unit comprising a carrier consisting of rings of staggered diameter which are arranged parallel to each other and spaced apart coaxially, and a plurality of rods positioned on said rings extending from two opposite sides of said carrier and arranged substantially parallel to each other and at least approximately evenly distributed over the whole surface of a cross sectional area perpendicular to said rods, said cross sectional area being of substantially circular or elliptical shape, the length of said rods decreasing from the center of said cross sectional area towards the periphery thereof in such a manner that the unit is substantially spherical or spheroidal.
Claim 2
Dependent Claim
139 words
A packing material unit for positioning in bulk or random relationship within a liquid-gas contact apparatus in order to enlarge the contacting surface of a liquid and a gas flowing through said apparatus, said unit comprising a carrier consisting of rings of staggered diameter which are arranged parallel to each other and spaced apart coaxially, and a plurality of rods positioned on said rings extending from two opposite sides of said carrier and arranged substantially parallel to each other and at least approximately evenly distributed over the whole surface of a cross sectional area perpendicular to said rods, said cross sectional area being of substantially circular or elliptical shape, the length of said rods decreasing from the center of said cross sectional area towards the periphery thereof in such a manner that the unit is substantially spherical or spheroidal.
Claim 3
Dependent Claim
12 words
The unit of claim 1, wherein said carrier is in basket shape.
Claim 4
Dependent Claim
22 words
The unit of claim 1, which comprises at least two rings in said carrier and at least four rods on each ring.
Claim 5
Dependent Claim
24 words
