[0029] In the embodiment, the connecting plate 26 and the connecting block 28 are an integrally formed structure, and the connecting block 28 is fixedly connected with the connecting rod 25 through bolts. The integrally formed connecting plate 26 and connecting block 28 have better connecting strength, which ensures the connecting firmness of the connecting plate 26 and the connecting block 28 and the fixing effect on the plate body 20, and the bolt fixing mode ensures the connecting firmness between the connecting rod 25 and the connecting block 28.

[0030] In the embodiment, the cross beam 21 is fixedly connected with the top of the plate body 20 through bolts, and the cross beam 21 is a finished product made of galvanized steel. The bolt fixing mode ensures the connecting firmness between the cross beam 21 and the plate body 20, thereby ensuring the fixing effect on the plate body 20, and the galvanized steel material has the advantages of corrosion resistance and high strength, thereby ensuring the service life of the cross beam 21.

[0031] In the embodiment, the overall shape of the connecting plate 26 is arc-shaped, and the outer wall of the connecting plate 26 is attached to the inner wall of the tower body 1. The arc-shaped design facilitates the connecting plate 26 to better attach to the inner wall of the tower body 1, thereby ensuring the installation stability of the plate body 20.

[0032] In the embodiment, the overall shape of the plate body 20 is circular, and the size of the plate body 20 is adapted to the size of the inner cavity of the tower body 1. This design facilitates the adaptive installation of the plate body 20 in the tower body 1, thereby ensuring the limiting effect of the plate body 20 on the filler body 15.

[0036] It should be noted that the plurality of through holes 200 in the embodiment are distributed in a matrix manner on the plate body 20, and this distribution manner makes the distance between the through holes 200 uniform, which is conducive to the uniform distribution and flow of fluid, and the uniform fluid distribution makes the contact of gas-liquid two-phase on the plate body 20 more sufficient, which helps to reduce the flow deviation and channeling phenomenon of fluid on the plate body 20, thereby improving the mass transfer and heat transfer efficiency.

[0037] When it is necessary to disassemble the pressing plate part 2, the user first pulls the connecting plate 26 from both sides to the inside, and the connecting plate 26 drives the insertion rod 27 to move and disengage from the insertion hole 16, and the connecting plate 26 simultaneously drives the connecting rod 25 and the sliding block 24 to move horizontally, and the sliding block 24 slides along the sliding groove 210, and the spring 23 is compressed by the sliding block 24. At this time, the limitation between the plate body 20 and the tower body 1 is removed, and finally the user can use hoisting equipment to hoist out the pressing plate part 2 from the inside of the tower body 1.
