Cascade Ring
Briefly introduces the structure and properties of plastic wreath fillers.
Cascade Ring
Cascade ring consists of multiple concentric rings arranged in an alternating pattern, resembling a flower, and is characterized by extremely high porosity and extremely low pressure drop.
Structural Features

Comparison with other packing materials
Comparison Items | Cascade Ring | Pall Ring | Multifaceted Hollow Sphere |
Porosity | 95%-98% | 85%-95% | 85%-90% |
Pressure Drop | Extremely Low | Medium | Low |
Specific Surface Area | 50-150 | 100-200 | 150-300 |
Mass Transfer Efficiency | Medium-Low | High | Medium |
Core Advantages
Extremely Low Pressure Drop: Porosity 95%-98%, pressure drop is only 30%-50% of Pall rings.
Good Anti-clogging: Open channels prevent solid particles from accumulating.
Lightweight: Weight is 50%-70% of Pall rings, requiring less support.
Not Easily Broken: Good plastic toughness, resilient.
Typical Applications
High-Volume Exhaust Gas Scrubber (Pressure Drop Sensitive)
Cooling Tower Water Spray Packing
Wet Desulfurization Flue Gas Uniform Distribution
High-Volume, Low-Concentration Gas Absorption
Selection Recommendations
Operating Conditions | Recommendation |
High air volume, pressure drop sensitive, low efficiency requirements | Cascade Ring |
Medium air volume, medium efficiency requirements | Hollow sphere packing |
High-efficiency distillation | Pall rings or structured packing |
Summary
The characteristics of plastic ring packing can be summarized as follows: extremely low pressure drop, highest porosity, good anti-clogging properties, and relatively low mass transfer efficiency. In applications such as large-volume exhaust gas scrubbing and cooling towers, where pressure drop is sensitive and efficiency requirements are not high, ring packing is the most economical choice. With a porosity as high as 95%-98%, it can significantly reduce fan energy consumption.
