Plastic Cascade Mini Ring Structural features

Open hole structure

The interlaced window design of the inner and outer layers prevents stress concentration and allows the impact force to be evenly distributed through the porous structure.

Reinforcement of internal and external ribs

The internal radial ribs create a skeletal support, whereas the external stepped ring wall diminishes the likelihood of crack propagation through arc-shaped transitions.

Length-to-diameter ratio optimization

The height-to-diameter ratio generally ranges from 0.3 to 0.5. The reduced axial dimension decreases the chance of fracture during vertical impacts.

Unique flanging design

The upper and lower edges of the packing are symmetrically shaped with flanges or protrusions, extending in a "wing-like" or "stair-like" manner. The flange height is usually 1/3 to 1/2 of the packing height, and the width is equivalent to the packing wall thickness.

Plastic Cascade Mini Ring Performance Advantage

1. Mass transfer performance

In comparison to conventional Raschig rings or Pall rings, the distinctive structural configuration of the step ring facilitates a more uniform distribution of gas-liquid mixtures, augments the interface area available for gas-liquid interaction, and enhances the mass transfer process. Consequently, this results in a significant improvement in separation efficiency. Following the implementation of plastic step rings in the refurbishment of a distillation column at a specific chemical plant, a 15% reduction in energy consumption, a 20% increase in production capacity, and a 30% decrease in maintenance costs were observed.

2.Other performances

The material boasts exceptional resistance to corrosion, substantial porosity, low energy consumption, a lightweight specific gravity, and facilitates straightforward loading and unloading procedures. It exhibits stable performance within both acidic and alkaline conditions. The material's significant porosity promotes the efficient circulation of gases and liquids, contributing to energy conservation and environmental sustainability, while also being cost-effective. Additionally, its light specific gravity simplifies the processes of loading and unloading.

Plastic Cascade Mini Ring Application

It is extensively employed in packed towers across industries including petroleum and chemical engineering. Utilizing its superior mass transfer efficiency and corrosion resistance, it facilitates processes such as gas-liquid separation and purification.
