PALL RING
PALL RING INTRODUCTION
Although the outer diameter of the ring is also equal to the height, two rows of Windows with internal protruding tongue pieces are opened on the ring wall, and each layer of window holes has 5 tongue pieces. This structure improves the gas-liquid distribution, makes full use of the inner surface of the ring, and improves the gas-liquid distribution and transmission efficiency. It is usually made of metal, plastic or ceramic. Pall ring packing has the advantages of large flux, small resistance, high separation efficiency and large operating elasticity. Under the same pressure reduction, the processing capacity can be more than 50% larger than that of the rasping ring.
