Stainless steel Bauer ring packing is made of sheet metal, and two rows of window holes with inner extension tongue are opened on the ring wall. There are five tongues in each row of window holes. Each tongue leaf bends towards the center of the ring and points to the center of the ring. Nearly the phase tower is in the center. The positions of the upper and lower window holes are staggered. Generally, the total area of the opening is about 35% of the total area of the ring wall, which enables the gas and liquid in the tower to pass freely through the window. at present, the packing of the Bauer ring is still being mined. One of the main ring fillers used.

Stainless steel Bauer ring packing has the advantages of high flux, low resistance, high separation efficiency and high operating flexibility. under the same pressure drop, the treatment capacity can be more than 50% larger than Lacy ring. At the same treatment capacity, the pressure drop can be reduced by half, and the mass transfer efficiency can be increased by about 20%. Compared with Lacy ring, this kind of packing has the characteristics of large production capacity, strong resistance and large operating flexibility. In general, the pressure drop is 50%-100% larger than Lacy ring under the same pressure drop, 50%-70% smaller than Lacy ring under the same pressure drop, and the tower height is also depressurized. Using Ball ring, the packing volume can be about 20%-40% larger than Lacy ring.
