Spherical packing made of plastic for mass and heat exchange columns

The innovation concerns a spherical packing made of plastic for mass and heat exchange columns, the shell of which is constructed in a lattice-like manner from parallel ring rods and meridian-like lattice rods, with one ring rod corresponding to the sphere diameter.

V/ Packings of the generic type are used to fill material and/or heat exchange columns, gas scrubbing towers, to form dry bodies, etc. They form a surface for material exchange or heat transfer. The packings should form as large a surface as possible, but on the other hand have a structure such that the pressure loss is as low as possible. The lattice-like spherical packings made of plastic have proven to be particularly suitable for this. The exchange surface formed by the packings in the columns _etc. is, however, essentially limited by the bulk density. To further increase the exchange surface, it is also known to mold rod-shaped noses onto the ring rods pointing into the interior of the sphere. Spherical packings of this type are usually injection-molded from plastic in a very complex manner.

&agr; In contrast, the innovation is based on the task

a spherical packing of the generic type

·

Type to be designed in such a way that the packing is suitable and adaptable for different operating conditions.

S This task is solved according to the innovation in that the filler consists of two hemispheres that are connected to one another by coupling elements or the like. This design has the significant advantage that another lattice-like filler with a smaller diameter can be inserted into the lattice-like filler that can be joined together. This significantly increases the exchange area. Furthermore, the production of the two lattice-like hemispheres from plastic by injection molding is much easier than with a spherical filler.

Preferably, each hemisphere is provided with a ring rod corresponding to the diameter of the ball, on which the coupling elements are arranged. Each hemisphere therefore has two equatorial ring rods which are placed against each other to couple the two hemispheres and are connected to each other by means of the coupling elements. A particularly simple production when injection molding from plastic can be achieved by connecting the ring rods of the two hemispheres corresponding to the diameter of the ball by a flat, elastic plastic web and arranging coupling elements on the opposite side. The flat, elastic web serves as a kind of hinge for folding the two hemispheres over, ensuring that the two equatorial ring rods are positioned precisely so that the coupling elements can engage with each other.

The ring rods are useful, the diameter of which

smaller than the diameter of the ball, with rod-shaped noses pointing into the inside of the ball. These are to be designed in such a way that they allow the insertion of a filling body of smaller diameter, but they can also reach into the interior of this lattice-like filling body of smaller diameter.

The coupling elements can be designed in different ways. For example, they can consist of pin-shaped projections and holes that are arranged opposite one another on the ring rods of the two hemispheres that correspond to the ball diameter and are designed as a snap closure.

The spherical filling body 1 is designed like a lattice and consists of two hemispheres 2 and 3. Each hemisphere 2 and 3 is provided with an equatorial ring rod 4 and 5. Furthermore, each hemisphere has 2 and 3 parallel ring rods 6 and 7 and meridian-like lattice rods 8 and 9. The two equatorial ring rods 4 and 5 are, as shown in particular in Figs. 2 and 3, connected on their outer circumference by a flat elastic web 10, which consists of the same plastic mass from which the two hemispheres 2, 3 are made. On the opposite side, the equatorial ring rods 6 and 7 are provided with an equatorial ring rod 4 and 5.

rod 4 has pin-shaped projections II formed thereon , while in a mirror-image position the equidistant ring rod 5 of the other hemisphere 3 is provided with corresponding holes 12. These pin-shaped projections 11 and holes 12 are designed as snap fasteners. Furthermore, both hemispheres 2 and 3 are provided with noses 13 and 14, respectively, which in the embodiment run parallel to the polar axis.

The filling body 1 is injection-molded from plastic, whereby the two hemispheres 2 and 3 are injection-molded in the position shown in Fig. 2 and 3, lying next to one another and connected through the web 10.

By folding over the two hemispheres 2 and 3, the spherical filling body 1 is formed, whereby on the one hand the web 10 serves as a hinge and on the other hand the pin-shaped projections 11 and holes 12 act together as a snap closure.

If required, a lattice-like packing element of smaller diameter can be inserted before the two hemispheres 2 and 3 are folded together, which is contained within the lattice-like packing element 1 after snap-closing. This achieves a larger exchange surface without increasing the filling volume in the mass or heat exchange column. This inserted lattice-like packing element can either be designed in accordance with the design according to Figs. 1 to 3, or in a conventional manner, i.e. without being able to be folded apart. If a collapsible packing element is inserted, a packing element can even be inserted inside this inserted packing element.
