    Summary

    The stepped ring is a new type of open hole packing developed by British mass transfer company. Its height is about half of the diameter, one side has a tapered flange, the ring wall has a window hole, and a curved blade extends to the ring center. Due to the special structure of reduced height and tapered flanging, not only the gas-liquid distribution in the packing layer is improved, but also the gas-liquid contact point is increased, which is conducive to the liquid convergence and dispersion and the continuous renewal of the membrane surface, so that the mass transfer is strengthened and the separation efficiency is greatly improved.

    Compared with Bauer ring packing, the flux and pressure of stepped ring packing can be increased by 10-20% and reduced by 30-40% respectively, and the separation efficiency can be improved in different degrees depending on the specific process. Up to now, more than 1000 step ring packed towers have been used in absorption, steam distillation and other operations around the world. According to the specific situation, the step ring can replace the west ring, the ball ring, the bubble cover plate, the float valve plate and the sieve plate, so as to achieve the purpose of high efficiency, high yield and energy saving.

    There are many kinds of materials for Woda metal step ring, such as carbon steel, stainless steel 304, 304L, 410, 316, 316L, etc., which can be selected.

    Advantages of Voda metal step ring:

      Reduce pressure drop:
      Metal step ring in the path of gas-liquid flow gap, large flux, can effectively reduce the pressure drop.
      Increase the reactor capacity:
      The increase of reactor capacity is the direct cause of the decrease of pressure drop. Xintao metal step ring keeps the reaction contact away from the pressure drop contact with overflow, which means that it can handle more gas and liquid and increase the capacity of reaction tower.
      Enhance anti pollution capability:
      The pointing position of Voda metal step ring maximizes the gap in the direction of gas-liquid flow, so any solid scale can pass through the packing layer with gas-liquid flow.
      Improve reaction efficiency:
      Voda metal step ring ensures that the ring surface is vertical rather than parallel to the greatest extent. This design has more advantages in mass transfer. Because the reaction efficiency depends on the size of the contact surface. Parallel faces are designed so that the inner face of the ring does not touch the liquid, creating a dry face. The dry surface hardly plays a role in mass transfer, but the vertical design of Xintao metal step ring greatly reduces the possibility of dry surface, thus effectively improving efficiency.
