[0040] In operation, high-temperature water to be treated is added to the upper tower body 2 through the water inlet pipe 3. Simultaneously, the drive motor 5 is started. The start of the drive motor 5 causes the drive rod 6 to rotate. As the drive rod 6 rotates, it causes the diffuser 7 to rotate. The rotating diffuser 7 disperses the incoming hot water through its surface holes. The dispersed hot water falls onto the drain plate 9. With the rotation of the deflector plate 8, the hot water is further dispersed and cooled, thus facilitating cooling. The arrangement of two sets of deflectors 8 and drain plates 9 ensures a stable cooling effect. Furthermore, as the dispersed hot water falls from the bottom drain plate 9, the rotation of the drive rod 6, along with the rotation of the drive rod 6, causes the bottom of the drive rod 6 to be driven by the first bevel gear 10 and the second bevel gear 11... The meshing mechanism drives the driven rod 12 to rotate. The protective cover 13 prevents corrosion damage at the connection between the first bevel gear 10 and the second bevel gear 11, thus improving the service life of the cooling tower. The rotation of the driven rod 12 drives the cooling fan 15 to rotate through the toothed belt 14 under the action of the gears. When the cooling fan 15 rotates, it blows cold air into the lower tower body 1 and carries the hot water out through the air outlet 16. The cooled water falls into the cooling chamber 17. The water falling into the cooling chamber 17 is filtered by the electronic valve 18 and then discharged through the drain pipe 4, achieving a multi-layer high-efficiency cooling effect and further improving the cooling effect of the cooling tower, enabling comprehensive and uniform cooling.

[0041] Example 2: Figures 1-8 The technical solution shown, based on Embodiment 1, discloses the following to address the problem of slow cooling speed in the cooling tower: a circulation pipe 20 is installed through the lower end of the cooling chamber 17, and an auxiliary cooling mechanism is provided at the upper end of the circulation pipe 20. The auxiliary cooling mechanism includes a water spray nozzle 22, the rear end of which is fixedly installed at the upper end of the circulation pipe 20. The auxiliary cooling mechanism includes a pressure pump 21, the lower end of which is connected to the circulation pipe 20, and the front end of which is fixedly installed on the rear outer wall of the lower tower body 1. The upper end of the nozzle 22 is fixedly installed on the upper inner wall of the upper tower body 2, and the output end of the nozzle 22 is aligned with the surface of the diffuser 7. An upper opening 23 is provided on the left side of the upper tower body 2, and a recovery chamber 24 is fixedly installed on the left side of the upper tower body 2. The recovery chamber 24 is correspondingly set with the upper opening 23. An inclined plate 25 is fixedly installed on the lower inner wall of the recovery chamber 24. The inclined plate 25 is inclined to the left. A condenser 26 is installed through the left side of the recovery chamber 24, and a recovery pipe 27 is connected to the lower end of the recovery chamber 24. The lower end of the recovery pipe 27 is connected to the left interior of the cooling chamber 17.

[0042] After the water is cooled, when it falls into the cooling chamber 17, the pressure pump 21 can be activated. The pressure pump 21 draws the water out of the cooling chamber 17 through the circulation pipe 20 and sends it to the spray nozzle 22. The water sent into the spray nozzle 22 is sprayed back onto the surface of the diffuser 7, thereby mixing and dispersing the cooled water with the uncooled water, achieving a mixed cooling effect and further improving the cooling efficiency of the cooling tower. At the same time, when the hot water is cooled, water vapor is generated. The water vapor passes through the upper opening 23 on the left side of the upper tower body 2 and enters the recovery chamber 24. The water vapor in the recovery chamber 24 is cooled and condensed in contact with the condenser 26. With the help of the inclined plate 25 at the bottom of the recovery chamber 24, it falls into the recovery pipe 27 and enters the cooling chamber 17. In this way, water vapor can be recovered, avoiding the waste of water resources and saving resources.

[0043] Example 3: Figures 1-10 The technical solution shown, based on Embodiment 2, discloses the following to address the problem of slow water vapor movement efficiency: a limiting rod 30 is fixedly installed on the right side of the lower tower body 1, and an auxiliary gas flow mechanism is provided on the right side of the limiting rod 30. The auxiliary gas flow mechanism is provided with a moving plate 29, and the middle end of the moving plate 29 is installed through the surface of the limiting rod 30. The auxiliary gas flow mechanism is provided with a reciprocating thread section 28, and the reciprocating thread section 28 is located on the right side surface of the driven rod 12. The reciprocating thread section 28 is threadedly connected to the upper end of the moving plate 29. A positioning rod 31 is installed through the lower end of the moving plate 29, and a striking plate 32 is fixedly installed on the left side of the positioning rod 31. Four protrusions are provided on the left end surface of the striking plate 32, and two vibration springs 33 are provided between the striking plate 32 and the moving plate 29.

[0044] When the driven rod 12 rotates to drive the cooling fan 15, the rotation of the driven rod 12 drives the reciprocating threaded section 28 on the right to rotate. The rotation of the reciprocating threaded section 28 drives the moving plate 29 connected to its surface thread. Under the limit of the limiting rod 30, the moving plate 29 can move left and right to adjust its position. When the moving plate 29 moves to the left, it strikes the lower tower body 1 through the striking plate 32. When the striking plate 32 contacts the lower tower body 1, it pushes the positioning rod 31 to the right and passes through the lower end of the moving plate 29, while squeezing the vibration spring 33. The setting of the vibration spring 33 can also improve the striking effect of the striking plate 32, so that the lower tower body 1 and the upper tower body 2 can vibrate, promote the gas flow inside the device, improve the heat dissipation efficiency, and increase the gas flow speed. The cooling efficiency of the cooling tower can also be improved. At the same time, the vibration setting can also prevent the filter screen 19 from clogging and achieve the anti-clogging effect.

[0045] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely exemplary of the principles and application of the present application. Numerous modifications and adaptions can be effected without departing from the spirit and scope of the present application, which is not limited to the exact construction and arrangement described. It is intended, therefore, to cover all modifications and adaptions that fall within the scope of the claims and their equivalents.
