Abstract: The present disclosure belongs to the technical field of packings, and in particular, to a packing element, a structured packing and an application of the structured packing. The packing element includes a collection-predistribution unit, a fluid uniform distribution unit, and an opening window unit that are sequentially arranged. The fluid uniform distribution unit includes a first substrate and a plurality of orifices arranged on the first substrate. Each orifice is circular and/or semicircular. Each orifice has an equivalent diameter of 1-5 mm. The opening window unit is provided with a plurality of windows, and each window has a length proportional to 0.5 power of the fluid viscosity. Fluid forms a confined free film in the window region of the opening window unit and wall-bounded film on the wall surface region.
