The metal cascade ring packing adopts an asymmetrical design: one side of the ring wall has window holes and outwardly curls tongue-like flaps, while the other side is a closed structure. This design enables the packing to form a more uniform inclined arrangement when piled up, with the void ratio reaching over 90%. The asymmetrical structure of the metal cascade ring packing significantly reduces the resistance of gas passing through the packing layer. The value of the metal cascade ring packing not only lies in the improvement of the efficiency of a single tower, but also in its optimization effect on the entire production system.

The value of metal cascade ring packing lies not only in the improvement of the efficiency of a single tower, but also in its optimization effect on the entire production system. In the waste gas treatment device of a certain chemical industrial park, after the RTO regenerative furnace adopted metal cascade ring packing, the VOCs removal rate increased from 85% to 98%. At the same time, due to the reduction in pressure drop, the thermal efficiency of the accompanying waste heat boiler increased by 12%, and the overall system energy consumption decreased by 25%. This dual improvement of "equipment performance + system energy efficiency" provides a practical and feasible technical solution for the green transformation of enterprises.
