The Pall ring packing is a new kind of packing, which is improved for some major shortcomings of the Raschig ring. It is a small rectangular window with six layers on the wall of the ordinary Raschig ring. The small window blades are placed at the center of the ring. The upper and lower window positions are formed by overlapping each other. The main difference between it and the Raschig ring packing is that there are rectangular window holes on the side walls, and the window leaves of the window holes are bent into the center of the ring. The distribution performance of gas and liquid is larger than that of the Raschig ring due to the opening of the ring wall. The improvement, especially the inner surface area of the ring, can be fully utilized.
PTFE Pall ring characteristics
High temperature resistance - use working temperature up to 160 °C.
High separation rate - has the advantages of large flux, low resistance, high separation efficiency and high operational flexibility, under the same pressure reduction,
The ration can be more than 50% larger than the Lacy ring. When the same amount is processed, the pressure drop can be reduced by half, and the mass transfer efficiency can be increased by about 20%. Low temperature resistance - good mechanical toughness; 5% elongation even at temperatures down to -196 °C. Corrosion resistance - It is inert to most chemicals and solvents, strong acid and alkali, water and various organic solvents. Weather resistant - the best aging life in plastics.
