Description

Technical Field

[0001] The present invention relates to the technical field of packed towers, and more specifically, to an integrated device of a packing retaining ring and a liquid distributor plate and an installation method thereof. Background Art

[0002] Packing retaining rings are widely used in packed tower equipment in industries such as petrochemical and fine chemical industries. In a packed tower, the packing retaining ring is located between the packing and the distributor, and is used to limit the packing below. It can prevent the relative movement of the packing during high gas velocity (high pressure drop) and sudden load fluctuations, thereby avoiding the loosening and breakage of the packing. The distributor includes a secondary tank of the distributor. The liquid distributor plate is a liquid guiding structure of the distributor located above the packing retaining ring, which can disperse the liquid sprayed onto the liquid distributor plate from the secondary tank of the distributor, thereby increasing the number of liquid distribution points. There needs to be a certain distance between the installation of the packing retaining ring and the distributor to ensure that the installation of the distributor is not affected when there is a deviation in the installation height of the packing.

[0003] Patent 201520742016.X discloses a packing retaining ring with a self-distribution function, including a grid structure and a liquid self-distribution structure composed of a surface distribution plate and a liquid guiding structure, which is used for a rectifying column with easily blocked systems or low liquid spray density.
