First, the characteristics of pall ring packing

Bauer ring has four advantages: small resistance, large flux, large flexibility of operation and high separation efficiency. Therefore, under the same pressure reduction conditions, its processing capacity is much larger than that of Lasichuan. If it is the same processing capacity conditions, its pressure can be reduced to less than half, and at the same time, its mass transfer efficiency can be improved by about 20%. It is characterized by its production capacity is very large, in the general case, the use of Bauer sequential use of Lacey ring to save about 35% of the packing volume.

II. Structure and function of Ball ring:

If according to the shape of the structure of the inner reinforcement can be divided into: the inner reinforcement for the well shape, generally known as plastic Bauer ring (well), the inner reinforcement for the meter type, known as plastic Bauer ring (meter). The design of the Bauer Ring allows liquids and gases to flow better and more evenly around the ring, and all aspects of the Bauer Ring have been improved. Therefore, under the same depressurization condition, its liquid phase distribution is very uniform, and the handling capacity is increased by 50% compared with the Rasch ring.

III. Specifications of Bauer ring:

The packing of the pall ring can be divided into three materials, one is metal, one is ceramic, and the other is plastic. Plastic pall ring is divided into 16 mm, 25 mm, 38 mm, 50 mm and 76 mm five specifications, with the increase of specifications, its specific surface area is getting smaller and smaller, the number of stacking is getting smaller, the corresponding stacking weight is also gradually reduced. The specifications of ceramic pall ring can be divided into 25 mm, 38 mm, 50 mm and 80 mm. The specific surface area of the four specifications is introduced from 238 to 75, and its void ratio increases from 0.73 to 0.8, while the number of piles and dry packing factor decreases accordingly. The metal pall rings can be divided into 16 mm, 25 mm and 38 mm, the same as the plastic rings. The specific surface area is reduced from 239 to 129, and the void ratio is increased from 92.8 to 94.5.
