Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, specifically to a dual-evaporation gravity turbine cooling tower. Background Technology

[0002] Traditional cooling towers only perform one evaporation cycle, resulting in an outlet water temperature higher than the local wet-bulb temperature. This cannot meet practical needs. To achieve a temperature lower than the air temperature, two methods are available: one is to use compressor cooling, which is costly; the other is to use a high-powered fan to create negative pressure in the cooling tower. However, this method consumes a large amount of electricity, and the fans are prone to breakage over time, causing damage. Summary of the Invention

[0003] In view of this, the main objective of this utility model is to provide a dual-evaporation gravity turbine cooling tower.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] This utility model provides a dual-evaporation gravity turbine cooling tower, including a tower body, a turbine assembly, a cooling assembly, a first evaporation assembly, a second evaporation assembly, a connecting assembly, and a recovery tank. The turbine assembly is located in the upper middle part of the tower body, the first evaporation assembly is located at the bottom of the turbine assembly, and the second evaporation assembly is located at the bottom of the tower body and below the first evaporation assembly.

The water turbine is mounted on the upper middle part of the tower body via the mounting base. The fan is mounted on the water turbine, and a humid air exhaust port is located above the fan. The water inlet of the water turbine is connected to the hot water pipe.

[0007] In the above scheme, the cooling assembly includes a first cooling pipe, a nozzle, and a second cooling pipe. One end of the first cooling pipe is connected to the water outlet of the water turbine, and the other end of the first cooling pipe is connected to the second cooling pipe. Several nozzles are installed inside the second cooling pipe.

[0008] In the above scheme, the first evaporation component includes a first evaporation layer, which is disposed at the bottom of the nozzle.

[0013] In the above scheme, a tower base is provided at the bottom of the tower body.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention utilizes a water turbine fan to force the humid air from the primary evaporation into a Venturi tube outside the tower, creating a negative pressure inside the tower and tube. This allows the incoming air to mix with the humid steam inside the tower, achieving secondary evaporation and cooling. Furthermore, the cooling water from the primary evaporation is rapidly sprayed out through nozzles from the lowest point of the tower using slender cooling pipes under gravity, creating a negative pressure. This mixes with the incoming primary steam, resulting in secondary evaporation, which is beneficial for cooling and saves a significant amount of water. Attached Figure Description
