The purpose of the utility model is accomplished through following technical scheme: the super tower tray is arranged in a tower body of a plate tower and comprises a tower tray plate, a plurality of stages of tower tray plates are sequentially arranged in the tower body from top to bottom, the left side and the right side of each circular tower tray plate are symmetrically cut off along the vertical direction, and a plurality of valve bodies are uniformly distributed on each stage of tower tray plate; a flow channel boundary is arranged between each stage of the tower tray plate to divide the tower tray plate into an upper flow channel and a lower flow channel, and the valve body directions of the upper flow channel and the lower flow channel of the same tower tray plate are opposite; a liquid receiving disc for containing liquid of the upper tray plate is arranged on one side of the upper runner, and a downcomer for guiding the liquid to the lower tray plate is arranged on the other side of the upper runner; liquid receiving discs and downcomers are arranged on two sides of the lower flow channel respectively, and the directions of the liquid receiving discs and the downcomers are opposite to those of the upper flow channel, so that the valve bodies on the tower disc plates of all levels are all towards the corresponding downcomers through the liquid receiving discs, and corresponding liquid flow channels are formed.
As a further technical scheme, a guide air hole is formed in the gap between the valve bodies.
As a further technical scheme, the guide air holes positioned in the upper flow passage of the tower tray plate and the guide air holes positioned in the lower flow passage of the tower tray plate are mutually rotationally symmetrical.
As the preferred technical scheme, the centers of all the tower tray plates are superposed with the central axis of the tower body.
The utility model has the advantages that: the improved tray efficiency is improved to 110-120%, gas-liquid and liquid-liquid contact in the tower is more sufficient, and the liquid flow direction is stable.

Description of reference numerals: the device comprises a tower body 1, a tower tray plate 2, a valve body 3, a guide air hole 4, a liquid receiving tray 5 and a downcomer 6.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings:
example (b): as shown in fig. 1, the super tray is installed in a tower body 1 of a plate tower, and includes a tray plate 2, wherein a plurality of stages of tray plates 2 are sequentially installed in the tower body 1 from top to bottom, and preferably, the centers of the tray plates 2 at all stages coincide with the central axis of the tower body 1. As shown in fig. 3, a part of the left and right sides of a circular tray plate 2 is symmetrically cut off along the vertical direction, a plurality of valve bodies 3 are uniformly distributed on each stage of tray plate 2, and a guide air hole 4 is formed in the gap between the valve bodies 3; a flow channel dividing line is arranged between each stage of the tower disc plate 2 to divide the tower disc plate 2 into an upper flow channel and a lower flow channel, the directions of the valve bodies 3 of the upper flow channel and the lower flow channel of the same tower disc plate 2 are opposite, and a guide air hole 4 positioned in the upper flow channel of the tower disc plate 2 and a guide air hole 4 positioned in the lower flow channel of the tower disc plate 2 are mutually rotationally symmetrical; a liquid receiving disc 5 for containing liquid of the upper-stage tray plate 2 is arranged on the right side of the upper runner, and a downcomer 6 for guiding the liquid to the lower-stage tray plate 2 is arranged on the left side of the upper runner; liquid receiving discs 5 and downcomers 6 are respectively arranged on two sides of the lower flow channel and are opposite to the upper flow channel in direction, so that the valve bodies 3 on the tray plates 2 of all stages are all towards the corresponding downcomers 6 through the liquid receiving discs 5 to form corresponding liquid flow channels, and the flow channel directions are shown in fig. 3.
The utility model discloses a working process: as shown in figure 1, liquid flow enters the tower from a liquid inlet at the top of the tower body 1, and gas flow enters the tower from a gas inlet at the side wall of the tower body 1; then the liquid flows to the topmost tray plate 2, as shown in fig. 3, the liquid flow is divided by the flow passage dividing line and enters the upper flow passage and the lower flow passage respectively, and under the flow guiding action of the valve body 3, the liquid flow flows in the flow passage direction shown in the figure and enters the next-stage tray plate 2 through the downcomer 6; liquid flow is contained and received by a liquid receiving disc 5 of the lower-stage tray plate 2, then continuously enters the next-stage tray plate 2 through a downcomer 6 under the flow guiding action of a valve body 3 until the liquid flow sequentially passes through all the tray plates 2 and is discharged from a liquid outlet at the bottom of the tower body 1.
