Features of Stainless Steel Metal Step Ring
Stainless steel metal 50 step ring is a new type of open-hole packing developed by the British Mass Transfer Corporation. Its height is about half of its diameter, one side has a tapered flange, a window hole is opened on the ring wall, and curved blades extend toward the center of the ring. Due to the reduced height and the special structure of the tapered flanging, not only the gas-liquid distribution in the packing layer is improved, but the gas-liquid contact point is increased, which is conducive to the concentration and dispersion of the liquid and the continuous renewal of the membrane surface so that the mass transfer is strengthened and separated The efficiency is greatly improved.
1. Improve reaction efficiency:
The metal step ring guarantees that its ring surface is vertical rather than parallel to the greatest extent. This design has more prominent advantages in mass transfer. Because the reaction efficiency depends on the size of the contact surface. The design of the parallel surface will prevent the inner surface of the ring from contacting liquid, thus forming a dry surface. Dry noodles hardly play a role in mass transfer, but the vertical design of the metal step ring greatly reduces the possibility of dry noodles, thereby effectively improving efficiency.
2. Enhance anti-fouling ability:
The pointing position of the metal step ring maximizes the gap in the gas-liquid flow direction, so any solid dirt can pass through the packing layer along with the gas-liquid flow.
3. Increase the capacity of the reaction tower:
The increase in the capacity of the reaction tower is the direct cause of the decrease in pressure drop. The metal step ring keeps the reaction contact away from the pressure drop contact accompanied by an overflow phenomenon, which means that more gas and liquid can be processed, and the reaction tower capacity is increased.
4. Reduce pressure drop:
The metal stepped ring has a large gap in the path of the gas-liquid flow and a large flux, which can effectively reduce the pressure drop.
