Ceramic Cascade Ring Product Description

The Ceramic Cascade Ring is a high-efficiency random packing further developed from the Ceramic Pall Ring and Raschig Ring. It features a reduced height-to-diameter ratio of 1:2 or 1:3, combined with a unique conical rolled edge (flared end) and a window design with five inwardly bent tongues per layer—staggered at 45° between upper and lower rows. This innovation reduces wall thickness, enhances mechanical strength, and makes it a preferred choice over conventional rings for energy-saving mass transfer systems.

Product Highlights

• Point-Contact Stacking for Low Pressure Drop: The asymmetric flared end disrupts linear contact, enabling point-contact stacking between rings. This increases void space, reduces gas flow resistance, and achieves 50-70% lower pressure drop compared to traditional Raschig rings.
• Acid & Heat Resistance: High-alumina ceramic (Al₂O₃ 17-23%) resists all inorganic and organic acids (except HF) and operates at temperatures ≥1000°C, ensuring stability in harsh chemical environments.
• Enhanced Mass Transfer Efficiency: The open window design (approx. 30% of wall area) and inner tongue leaves allow gas and liquid to pass freely, utilizing the inner surface for better distribution and 50-100% higher treatment efficiency than Raschig rings.
• Strong Mechanical Durability: The rolled end reinforces the ring's structure, while the high-density ceramic body ensures high compressive strength and long service life under heavy load.
• Versatile Application Range: Suitable for drying, absorption, cooling, scrubbing, and regeneration towers across chemical, metallurgy, coal gas, and oxygen production industries.
• Standards Compliant: Manufactured in accordance with GB/T 18749-2008 standard for chemically resistant ceramic tower packing, ensuring consistent quality across all batches.
