[0033] The wave crest 1 of the corrugated plate packing piece is discontinuously provided with a window 4. The side of the window 4 is rectangular. Due to the existence of the structure of the window 4, the liquid flowing downward along the surface of the corrugated plate packing piece under the action of gravity will be in a film shape at the window 4, and part of the liquid will be guided to the other side of the corrugated plate packing piece, increasing the liquid film turbulence degree of the gas-liquid phase, the liquid film is updated faster, the gas-liquid mass transfer efficiency is improved, and the gas-liquid mass transfer area is increased. Improve the flow direction of the gas, form liquid film exchange, which is beneficial to the lateral diffusion of the gas phase, and reduce the pressure loss.

[0035] The local reverse corrugated structure 3 directly contacts with the adjacent corrugated plate packing piece, and plays a role in stabilizing the distance between the adjacent corrugated plate packing pieces. The regular packing block composed of the corrugated plate packing pieces does not need a distance column, and has the advantages of simple structure, convenient assembly and low cost.

[0036] When the packing is installed in the packing tower, the corrugated plate packing pieces of the upper and lower two discs of the packing are rotated by 5°-10° during installation.

[0037] The corrugated plate packing piece is made of metal, ceramic or plastic.
