PTFE raschig ring is a loose packing. The shape is simple. It is a circle whose height is equal to its diameter. Rasicyclic ring has excellent resistance to acid and heat, resistance to various inorganic acids, organic acids and organic solvents except hydrofluoric acid corrosion, can be used in a variety of high temperature occasions.
PTFE Polytetrafluoroethylene Pall ring (100% pure PTFE) is a kind of special plastic random packing designed to serve special working environment and applications.
The raw materila PTFE advantages
1.Excellent corrosion resistant
2.Excellent temperature resistant :from -200 degrees to +260 degrees
3.Long time uselife
4.Extremely low surface energy, highly hydrophobic
The features of two type rings
| Features | PTFE raschig ring | PTFE pall ring |
| Structure | Hollow column, thin wall 。 | Improved on raschig ring ,have window on the wall,and a part of window pane bend toward to the center of the ring 。 |
| Fluid and mass transfer properties | 1. Fixed gas-liquid path， 2. Small effective surface area 。 3. big resistant ，low flux。 4. low transfer |
1. improved the gas-liquid distribution
2. Big effective surface area,high usage 3. lower resistant ，improve the flux 4. Better transfer ,higher 30-50% base on the same size |
| Main advantages |
2. Apply for the lower efficiency ,high corrosion resistant occasion 。 |
1. High efficiency,high flux,low pressure drop
2. Stronger anti-clogging ability |
| Application | 1. Absorption and washing of strong corrosive media。 2.Anti-corrosion filling with low requirements for pressure drop and efficiency
。 |
1.Distillation, absorption, desorption and scrubber towers for highly corrosive substances (such as sulfuric acid, chlor-alkali, hydrofluoric acid, bromine and other industries)
2. Waste gas treatment with low pressure drop and high throughput (such as acid mist absorption) is required. |
