  • Patent number: 8871012
    Abstract: A packed column includes a regular packing (8) and a liquid distribution plate (5). The regular packing (8) is constructed by combining two or more hollow columns, and the hollow columns each have a cross section of circular shape, hexagonal shape or other shapes. The liquid distribution plate (5) has small holes under which liquid guide tubes (4) are connected. The liquid guide tubes (4) lead to all hollow columns of the packing (8). The liquid distribution plate (5) is horizontally installed above the regular packing (8) in a column body (2). Each gas guide plate (11) is made by rotating and twisting a rectangular plate and has several protrusions (12) on its side. The gas guide plates (11) are installed in the hollow columns of the regular packing (8) with the height slightly smaller than that of the hollow columns. A gas outlet (3) is located between the regular packing (8) and the liquid distribution plate (5).
