The polyhedral hollow ball is composed of two hemispheres of a ball, each hemisphere is opened with 12 half fan-shaped blades, the two hemispheres of the fan-shaped blades staggered each other, the polyhedral hollow ball has a reinforcement ring along the whole circumference of the middle, in the upper and lower of the ring there are 12 spheres. The upper and lower spheres interlace each other and are arranged radially along the central axis. The filler is characterized by large specific surface area and high voidage. However, due to the large number of leaves, there is a shielding effect between each other, which is not conducive to liquid distribution and wetting. Most of the liquid gathered in the hollow column of the sphere, blocking the flow of gas, so the resistance is large. This kind of filler is mostly used in water treatment projects.

Features:

1, high gas speed, many blades, small resistance;

2. Large specific surface area, which can fully solve gas-liquid exchange;

3. The multi-sided hollow ball has the characteristics of large production capacity, small resistance, large operation elasticity and so on.

4. Light weight, high strength, large free space, high temperature resistance, corrosion resistance, good surface hydrophilicity, small wind resistance, less power consumption, large specific surface area and suitable for a variety of solvent processing device.
