The multi-faceted hollow ball is made of polypropylene plastic. It is composed of two hemispheres to form a fishing net-like sphere. Plastic woven wire or a small piece of sponge is placed in the center. There is a reinforcement ring in the middle of the ball along the entire circumference. The two balls are staggered. There is a reinforcement ring in the middle of the ball along the entire circumference. There are 12 petals (not 10) on the upper and lower sides of the ring, a total of 24, in the shape of semi-fan-shaped leaves, of which the Ф100mm leaves are increased to 44, 22 each, and the effect is more than 1 times higher than ordinary ones!

Advantages of polyhedral hollow balls:

The advantages of polyhedral hollow balls are full three-dimensional structure, no need for fixation, easy film hanging, no clogging, high gas velocity, many blades, light weight, low resistance, high strength, large operating flexibility, large specific surface area, large free space, high temperature resistance, corrosion resistance, good surface hydrophilicity, small wind resistance, low power consumption, large gas-liquid contact area, high porosity, large production capacity, high mass transfer efficiency, small aperture on both sides, less residual sludge, long life, easy installation, can fully solve gas-liquid exchange, and adapt to a variety of solvent treatment devices.

Disadvantages of polyhedral hollow balls:

However, due to the large number of blades, there is a shielding effect between each other, which is not conducive to liquid distribution and wetting; most of the liquid gathers in the hollow column of the sphere, hindering the smooth flow of gas, so the resistance is relatively large. This kind of filler is mostly used in water treatment projects.

Application of polyhedral hollow balls:

Polyhedral hollow balls are a new type of high-efficiency tower filler widely used in water treatment equipment. They are also widely used in power, chemical, papermaking, environmental protection and other industries. Specifically, they can be used in domestic sewage, oil-water separation, seawater desalination, pure water, wastewater treatment, power plant desulfurization, decarbonation, decarbonation, petrochemical, light industry papermaking, food industry brewing, sugar textile, printing and dyeing leather, pharmaceutical, power plant carbon dioxide degassing tower, contact reaction tower, etc.
