产品介绍.jpg


       Plastic Bauer ring packing is a kind of open-hole ring packing with the same height and diameter. Each layer of window has five tongue leaves, each of which points to the ring center. The upper and lower layers of window holes are staggered in opposite positions. Generally, the opening area accounts for about 30% of the total area of the ring wall. It is characterized by large void ratio, low pressure drop and mass transfer unit height, high flooding point, sufficient vapor-liquid contact, small specific gravity and high mass transfer efficiency. This structure improves the vapor-liquid distribution and makes full use of the inner surface of the ring, so that the gas and liquid in the packing tower can freely pass through the window.
      

功能特点.jpg


      The Bauer ring is greatly improved on the lacI ring. Although the outer diameter of the ring is also equal to the height, two rows of windows with inner tongue are opened on the ring wall. Each window hole has 5 tongue pieces. This structure improves the gas-liquid distribution and makes full use of the inner surface of the ring. Compared with lacI ring, the treatment capacity can be more than 50% and the pressure can be reduced by half.

      Generally, the opening area accounts for about 30% of the total area of the ring wall. Without increasing the surface area of the packing, the flow of gas-liquid two-phase in the packing layer is greatly improved, and the hydrodynamics and mass transfer performance of the packing are improved.
