Rectangular Saddle Rings
Rectangular Saddle Rings
Rectangular saddle rings are a type of high-efficiency random packing material. Their unique saddle-shaped structure gives them excellent performance in terms of pressure drop, flux, and mass transfer efficiency.
Shape Characteristics
Features | Description |
Saddle-shaped curved surface | Symmetrical arc shape with no sharp corners |
Rectangular opening | Side windows increase gas-liquid passageway |
Reinforcing ribs | Inner wall reinforcing ribs improve strength |
Smooth edges | Reduce liquid retention |
Compared to earlier arc-shaped saddle rings, rectangular saddle rings exhibit greater structural stability and higher packing regularity.
Fluid Dynamics Properties
Performance | Values/Comparisons | Explanations |
Porosity | Metals 85%-95%, Ceramics 70%-80% | High porosity, low resistance |
Pressure Drop | 20%-30% lower than Pall rings | Smoother airflow due to curved surface |
Flooding Velocity | 15%-25% higher than Pall rings | Stronger liquid redistribution capability |
Mass Transfer Efficiency
High Surface Utilization: Uniform liquid film distribution on the arc-shaped surface, no stagnant zones.
Strong Self-Distribution Capability: Liquid is repeatedly cut and dispersed, suppressing wall flow.
Enhanced Turbulence: Openings and reinforcing ribs disturb the gas-liquid mixture, increasing interfacial renewal.
Under the same conditions, the mass transfer efficiency of the rectangular saddle ring is 10%-20% higher than that of the Pall ring.
Applicable Scenarios
High-vacuum distillation (low pressure drop)
High-throughput absorption towers
Pressure drop-sensitive systems
Easy-to-foam systems
Selection: Prioritize metals for pressure drop, ceramics for corrosive media, and plastics for organic systems.
Summary
The core advantages of the rectangular saddle ring can be summarized as: 20%-30% lower pressure drop than the Pall ring, 15%-25% higher flooding velocity, and 10%-20% higher mass transfer efficiency. Suitable for pressure drop-sensitive applications with high throughput requirements. We are a Chinese supplier of rectangular saddle rings.
