DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0017] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 shown, this high-efficiency closed cooling tower includes a cooling tower main body 1, a spray pump 2, a spray pipe 3, an air inlet grille 4, a cooling tray 5 and a fan 6. The spray pipe 3 extends into the cooling tower main body 1, and a plurality of nozzles 7 for spraying liquid are arranged on the spray pipe 3 inside the cooling tower. A water filter plate 8 that extends obliquely from the middle to both sides is arranged inside the cooling tower main body 1, and the inside of the water filter plate 8 is hollow and layered;

[0018] A coarse dehydration layer 9 for coarse adsorption and filtration is arranged below the inside of the water filter plate 8, a fine dehydration layer 10 for fine filtration and adsorption is arranged above the inside of the water filter plate 8, a plurality of diversion rods 11 are arranged between the coarse dehydration layer 9 and the fine dehydration layer 10, a diversion plate 12 is arranged between the diversion rod 11 and the fine dehydration layer 10, and a plurality of filter holes 13 for allowing water vapor to pass through are arranged on the diversion plate 12.

[0019] The flow guide plate 12 is arranged in a conical shape from both sides of the flow guide rod 11 towards the fine dehydration layer 10. The filter holes 13 pass through the flow guide plate 12 from below the flow guide plate 12 and extend above the flow guide plate 12, and are arranged in a frustum shape with a smaller upper part and a larger lower part. An arc-shaped flow guide protrusion 14 is arranged below the flow guide rod 11.

[0020] A water storage bin 15 is arranged below the cooling tower main body 1. The spray pipe 3 is communicated with the water storage bin 15.
