Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in the accompanying drawings 1 to 4, the liquid collecting redistributor of the packed tower comprises a wall ring 1, a liquid collecting plate 2, an air outlet pipe 3 and a liquid distribution component, wherein the liquid collecting plate 2 is coaxially arranged in an inner cavity of the wall ring 1, the liquid collecting plate 2 is of a funnel-shaped plate body structure, a liquid outlet 4 is formed in a through mode in the central area of the liquid collecting plate 2, the air outlet pipe 3 is axially arranged on the liquid collecting plate 2 in a penetrating mode, the liquid distribution component is correspondingly arranged below the liquid outlet 4 at intervals, and liquid flowing out of the liquid outlet is distributed layer by layer in the radial direction of the wall ring through the liquid distribution component.

The liquid distribution assembly comprises a plurality of groups of distribution plates 5 which are distributed along the axial interval of the wall ring, the three groups of distribution plates are arranged in the embodiment, a plurality of connecting columns 11 are arranged between two upper and lower adjacent distribution plates 5, and the connecting columns 11 are arranged in a circumferential array mode. From last a plurality of to distributing the outer fringe of distributing plate 5 increases from the beginning to the end in the radial direction, also in a plurality of that distribute down the diameter of distributing plate 5 increases in proper order, a plurality of groups distribution weeping hole 6 have been seted up on distributing plate 5, and are located the distribution weeping hole that corresponds to the top on distributing plate 5 of distribution weeping hole 6 below has seted up logical liquid mouth 7, and upper distributing plate continues to flow through gravity through the liquid that distributes weeping hole 6 and flow downwards, and the in-process that falls through the logical liquid mouth 7 of lower floor's distributing plate to fall into the below of distributor body.
