Referring to fig. 1-5, the sieve plate of the present invention includes a sieve plate body 12, and a plurality of spiral bubbling holes 11 are disposed on the sieve plate body 12. The drum bubble hole 11 includes: a linear spiral hole 111 and first circular holes 112 connected to both ends of the spiral hole 111. The sieve plate body 12 is circular, comprising: an ineffective area 101 with circular arc-shaped upper and lower ends, a separation area 102 with circular arc-shaped left and right ends, a bubbling area 104 positioned in the middle of the ineffective area 101, and two downcomer areas 103 positioned between the separation area 102 and the bubbling area 104; the drum cells 11 are distributed in the bubbling region 104. The diameter of the first circular hole 112 is larger than the width of the spiral hole 111.
The spiral bubbling holes 11 are small in processing difficulty and low in cost, and gas in the tower penetrates through the sieve plate more uniformly. In the case of the same cross-sectional area of the bubbling region 104, the number of spirals is greater and the distribution is more uniform. The gas is easier to be divided through the linear spiral hole 111, and a better gas-liquid mass transfer effect is achieved. In addition, the linear spiral hole 111 is matched with the first round hole 112, in the rectification process, when the ascending steam volume is small, the ascending gas pressure is small, and when the liquid storage volume on the sieve plate body 12 is fixed, the ascending steam passes through the first round hole 112, so the sectional area is small; when the amount of the ascending steam is large, the pressure of the ascending gas is large, and the amount of the liquid stored in the sieve plate body 12 is constant, the ascending steam passes through the screw hole 111 and the first circular hole 112 together, so that the sectional area is large. Namely: the cross section area of the ascending steam drift diameter can be automatically adjusted and changed according to the quantity and the pressure of the ascending steam, and the gas-liquid mass transfer effect is further enhanced.

The sieve plate is applied to sieve plate towers in various occasions through the second circular holes 113 with proper quantity, and good gas-liquid mass transfer effect is kept.
The drum hole 11 may have a circular spiral shape. The spiral shape may be a regular polygon (regular triangle, regular quadrangle, regular pentagon, regular hexagon), or a regular triangle, as shown in fig. 5. In particular, the spiral hole 111 is circular or regular polygon. The circular spiral shape can improve the utilization rate of the bubbling area as much as possible, so that the gas can penetrate through the sieve plate more uniformly.
