  • Patent number: 10888835
    Abstract: A tower packing element (100), a tower packing (300), a packing tower, and a mixer including the tower packing element (100) are provided. The tower packing element (100) are manufactured by a deformed plate and includes a plurality of strip assemblies (10) arranged along a longitudinal direction of the tower packing element (100) and a connecting plate portion (20) connected between adjacent strip assemblies (10). Each of the strip assemblies (10) defines a central passage (30) therein, and the central passage (30) is extended in a lateral direction of the tower packing element (100). The connecting plate portion (20) is extended along the lateral direction of the tower packing element (100). The adjacent strip assemblies (10) and the connecting plate portion (20) connected therebetween define a side passage (40) parallel to the central passage (30).
