Plastic saddle ring is a loose land filler widely used in chemical, environmental protection and other industries, and is an improved form of saddle filler. It shows excellent performance in the process of gas-liquid mass transfer through its unique design and material characteristics.

一、Structural characteristics

1. Shape design

The shape of the plastic rectangular saddle ring is between the ring and the saddle, and adopts a rectangular cross-section design to avoid the problem of easy cladding of traditional arc saddle fillers. The radii of curvature in and out are different, which makes the filler form a uniform bed porosity when it is stacked, and improves the uniformity of gas-liquid distribution.

2. Surface characteristics

The filler surface may have grooves or protrusions, increasing the gas-liquid contact area and further promoting mass transfer efficiency.

二、Material and performance

1. Common materials

Plastic saddle rings are usually made of plastics such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC), polyvinylidene fluoride (PVDF). These materials have good corrosion resistance, temperature resistance and mechanical strength, and are suitable for a variety of working conditions.

2. Performance advantages

High Flux: The rectangular cross-section design reduces the resistance to gas passing through and increases gas-liquid flux.

Low pressure drop: The bed has uniform porosity, smooth gas flow, and reduced pressure.

High efficiency: sufficient gas-liquid contact and high mass transfer efficiency.

Good stain resistance: The plastic material has a smooth surface, is not easy to scale, and is easy to clean and maintain.

High load elasticity: It can adapt to large gas-liquid load changes and has good operating elasticity.
