FIG. 3 is a schematic structural view at A of the present invention;

in the figure: 1. a liquid collection pan; 11. a filter screen; 2. a collection chamber; 3. a gas lift pipe; 31. capping; 4. a step; 5. a tapered opening; 6. a circular hole; 7. a liquid flow aperture; 8. a support leg; 9. and (4) distance blocks.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by a person skilled in the art without any inventive work based on the embodiments of the present invention belong to the protection scope of the present invention.

Referring to fig. 1-3, the utility model provides a technical solution: its structure includes liquid collecting tray 1, liquid collecting tray 1 has collection chamber 2 and gas riser 3, install filter screen 11 in the middle of the 1 upside of liquid collecting tray, liquid collecting tray 1 is outwards provided with multiunit gas riser 3 by its center, and the upper end of gas riser 3 stretches into in the collection chamber 2, the lower tip of gas riser 3 stretches out outside collection chamber 2, the upper end of gas riser 3 is the closed form to install the block 31, the lower extreme of gas riser 3 is equipped with step 4 and toper opening 5, toper opening 5 both sides are provided with round hole 6, gas riser 3 stretches into be provided with the liquid flow hole 7 that is linked together with corresponding gas riser 3's lower extreme opening on the part of collection chamber 2.

Specifically, the liquid collecting tray 1 is a circular structure with an open upper end and a closed lower end.

Specifically, the steps 4 are two steps arranged at equal intervals, and the horizontal steps have a buffering effect, so that liquid has enough time to gather.

Specifically, circular truncated cone wall round holes 6 on the left side and the right side of the conical opening 5 are symmetrically designed, so that liquid can be guided out quickly, the distribution efficiency of the liquid redistributor is improved, and blockage is prevented.

Specifically, the angle between the conical opening 5 and the horizontal plane is 60 °.

Specifically, the outer wall of the liquid collecting tray 1 is provided with the supporting legs 8 and the distance blocks 9, the design of the supporting legs 8 and the distance blocks 9 can ensure the simplicity of three-point positioning plane in the fixing and installation between the supporting legs and the tower wall, and the supporting legs can be directly installed on the filler by virtue of the self weight of the redistributor.
