The ball is made of polypropylene (PP) plastic, which is composed of two hemispheres into a ball. Each hemisphere has 8-12 half sector blades according to the design requirements, and the fan blades of the two hemispheres are staggered with each other. The filler is characterized by large specific surface area and high void ratio. However, due to the large number of blades, there is shielding effect between them, which is not conducive to the distribution and wetting of the liquid; most of the liquid accumulates in the hollow column of the sphere, which hinders the smooth flow of the gas, so the resistance is large.
● the plastic polyhedral hollow ball (PP, PE, PVC, CPVC, RPP) is composed of two hemispheres into a sphere, each hemisphere is provided with 12 half fan-shaped blades, and the fan-shaped blades of the two hemispheres are staggered with each other.
● light weight, high strength, large free space, high temperature resistance, corrosion resistance, good surface hydrophilicity, small wind resistance and low power consumption. Output device with large specific surface area and suitable for various solvents.
This kind of packing is mostly used in water treatment engineering and widely used in environmental protection equipment such as chlorine remover, deaerator, carbon dioxide absorption tower, waste gas purification tower, acid mist purification tower, etc.
