Plastic Polyhedral Hollow Ball Product Description

The Plastic Polyhedral Hollow Ball is a new-type high-efficiency tower packing composed of two hemispheres that assemble into a hollow sphere. Each hemisphere contains twelve half-fan-shaped blades, and the upper and lower blades are arranged in a staggered pattern. This polyhedral design prevents the packing from bridging or creating hole effects during stacking, ensuring even gas and liquid distribution throughout the bed. Manufactured from chemically resistant thermoplastics including PP, PE, PVC, CPVC, RPP, and PVDF, it offers excellent resistance to acids, alkalis, and organic solvents across a wide temperature range. The hollow spherical geometry provides large surface area, high voidage (84%–92%), and low gas flow resistance, promoting efficient mass transfer and reaction. It is widely used in water treatment, CO₂ removal in power plants, desulfurization, oil-water separation, wastewater treatment, and gas purification towers, and is produced in accordance with HG/T 21556.3-1995.

Product Highlights

• Unique Polyhedral Structure: Two hemispheres with 12 staggered half-fan blades each create a large effective surface area while preventing bridging and hole effects, ensuring uniform gas-liquid contact.
• Large Surface Area & High Voidage: Surface area reaches 150–460 m²/m³ with voidage of 84%–92%, providing ample contact area and free flow paths for gas and liquid.
• Low Resistance & High Throughput: The hollow, open structure minimizes pressure drop and allows high gas velocities, reducing energy consumption in scrubbers and treatment towers.
• Excellent Chemical Resistance: Available in PP, PE, PVC, CPVC, RPP, and PVDF to withstand acids, alkalis, and organic solvents across operating temperatures from ≤60°C (PVC) up to ≤150°C (PVDF).
• Lightweight & Easy to Install: Low bulk density reduces tower structural load, and the balls are easy to pour, load, and replace.
• Versatile Application Range: Suitable for water treatment, CO₂ removal, desulfurization, oil-water separation, wastewater treatment, gas purification, acid mist suppression, and seawater desalination.
