Abstract

A blank for forming a spherical filling body for material-exchange columns is formed by stamping from a strip sheet of metal series of tongue-like elements extending from a middle strip. The spherical body can be formed by bending the tongue-like elements into a curved form, then bending the middle strip to form a ring. The tongue-like elements provide a plurality of drip edges to facilitate the interaction of the liquid and the gas in the material exchange column. Additional elements can be formed with the tongue-like elements to provide additional drip edges when the filling body is assembled.

Claims

1. A plate-shaped blank for the manufacture of a spherical filling body for material exchange columns comprising:

a middle strip; and

a plurality of tongue-like elements extending from the sides of the middle strip, each curved in substantially the same direction and each taper from the end adjoining the middle strip to the free end, the width of the tongue-like element at the middle strip greater than the distance between two adjacent tongue-like elements, said tongue-like elements additionally include stamped-out sections along the length thereof to define a surface section, said surface section bent in a direction opposite the curve of the tongue-like elements, and flap-like elements extending from the ends of the tongue-like elements, the flap-like elements shorter than the tongue-like elements from which they extend.

2. A blank as defined in claim 1, wherein the tongue-like elements which are curved or bulge in opposite directions have two side strips.

3. A plate-shaped blank for the manufacture of a shperical filling body for material exchange columns, comprising:

a middle strip; and

a plurality of tongue-like elements extending from the sides of the middle strip, each tongue-like element having an end adjoining the middle strip and a free end, the width of the tongue-like elements at a point remote from the middle strip less than the width of the tongue-like elements at the point at which they join the middle strip, said tongue-like elements additionally include stamped-out sections along the length thereof to define a surface section that can be bent separately from the remainder of the tongue-like element.

4. A substantially spherical metal filling body for exchange columns comprising:

an equatorial ring;

a plurality of tongue-like elements having free ends, and extending in opposite directions from the equatorial ring, wherein the tongue-like elements are curved so that the free ends of the tongue-like elements extending in one direction from the equatorial ring are relatively near one another to form a first polar region, and the free ends of the tongue-like elements extending in the other direction from the equatorial ring are relatively near one another to form a second polar region.

5. A filling body as defined in claim 4, wherein at least some of the tongue-like elements have elongate stamped out sections that are curved opposite the curve of the tongue-like elements.

6. A filling body as defined in claim 4, additionally comprising a plurality of flap-like elements, each extending from the free end of one of the tongue-like elements into the interior of the sphere.

7. A filing body as defined in claim 6, wherein the flap-like elements extend substantially perpendicular to the plane defined by the equatorial ring.

8. A filling body as defined in claim 6, wherein at least some of the flap-like elements have stamped out sections forming projecting elements.

9. A filling body as defined in claim 6, wherein at least some of the tongue-like elements have elongate stamped out sections that are curved opposite the curve of the tongue-like elements.

10. A substantially spherical metal filling body for exchange columns comprising:

an equatorial ring;

a plurality of curved tongue-like elements extending in a meridian-like manner from either side of the equatorial ring, wherein;

the free ends of the tongue-like elements form two polar regions; and

at least some of the tongue-like elements each include an elongate stamped out section curved opposite the curve of the tongue-like element; and

a plurality of flap-like elements, each extending from the free end of one of the tongue-like elements into the interior of the sphere.

11. A filling body as defined in claim 10 wherein at least some of the flap-like elements have stamped out sections forming projecting elements.
