1. Structural advantages

Annular design and side wall openings:

Plastic pall rings adopt an annular structure with rectangular windows on the side walls, and the window blades are bent into the center of the ring. This design increases the specific surface area of the packing and improves the gas-liquid distribution, making the gas and liquid contact more fully in the packing layer.

Porosity optimization:

The packing has a large porosity inside, which reduces the resistance to fluid flow, increases the contact opportunity between the gas and liquid phases, and promotes the mass transfer process.

2. Working principle

Fluid rotation and mixing:

When the fluid passes through the plastic pall ring packing layer, a rotating flow is formed, which increases the contact area between the fluid and the packing and prolongs the gas-liquid contact time.

Component separation mechanism:

Due to the different adsorption, decomposition and diffusion rates of different components on the packing surface, the plastic pall ring packing can achieve efficient component separation and improve mass transfer efficiency.

3. Technical details and performance improvement

Improved processing capacity:

Under the same pressure drop, the processing capacity of the plastic pall ring packing is more than 50% higher than that of the traditional Raschig ring. This means that under the same operating conditions, plastic pall ring packing can handle more gas-liquid mixtures.

Improved mass transfer efficiency:

The mass transfer efficiency of plastic pall ring packing is about 20% higher than that of traditional packing. Its unique structural design makes the gas-liquid contact more complete and the mass transfer process more efficient.

Reduced pressure drop:

Due to the smaller fluid flow resistance in the packing layer, the pressure drop of plastic pall ring packing is 50%-70% lower than that of traditional packing. This not only saves energy consumption, but also improves the throughput and processing capacity of the equipment.
