Problems solved by technology

[0003] The saturated air at the air outlet of the closed cooling tower not only consumes a lot of water resources, but also produces a lot of white fog in winter, which not only affects the urban landscape, but also causes the temperature in the downwind area to rise, and may cause Legionella to spread with the fog

Embodiment 1

[0023] refer to figure 1 A closed cooling tower that can eliminate saturated air at the air outlet is shown, including heat dissipation fins 1, blower fan 2, water eliminator 3, spray pipeline 4, heat dissipation pipe 5, water collection tank 6 and shell 7 ; The heat dissipation fins 1, blower fan 2, water collector 3, spray pipeline 4, heat dissipation pipe 5 and water collection pool 6 are horizontally arranged in the housing 7 from top to bottom, and the heat dissipation fins 1 and The radiating pipe 5 communicates.

[0024] In actual use, the heat dissipation fin 1 is placed on the top of the blower fan 2, the circulating water enters the heat dissipation fin 1 to absorb the heat of the hot and humid air, and then enters the heat dissipation pipe 5 for cooling, and the spray water passes through the spray pipeline 4 to spray the spray water Sprinkle onto the heat dissipation pipe 5 to absorb heat, evaporate during the heat absorption process, and generate water vapor. Und...

Embodiment 2

[0029] refer to figure 1 As shown, a closed cooling tower capable of eliminating saturated air at the air outlet is based on the first embodiment: the top of the housing 7 is provided with an air outlet, the side wall of the lower part of the housing 7 is provided with an air inlet, and the upper part of the housing 7 is provided with an air outlet. There is a circulating water inlet, the middle part of the housing 7 is provided with a spray water inlet, and the lower part of the housing 7 is provided with a circulating water outlet; the water inlet of the cooling fin 1 is connected with the circulating water inlet on the housing 7, and the cooling fin 1 The water outlet is communicated with the water inlet of the radiating pipe 5, and the water outlet of the radiating pipe 5 is connected with the circulating water outlet on the housing 7; the spraying pipeline 4 is connected with the spraying water inlet on the housing 7.

[0030] In actual use, the technical solution is adop...

Embodiment 3

[0032] refer to figure 1 The shown closed cooling tower that can eliminate the saturated air at the air outlet is based on the first or second embodiment: the heat dissipation pipe 5 adopts a coiled pipe or a Z-shaped pipe.

[0033] In actual use, the heat dissipation pipe 5 adopts a coiled pipe or a Z-shaped pipe, so that the effect of heat dissipation is better.

Abstract

The invention belongs to the technical field of cooling towers, and particularly relates to a closed cooling tower and a method for eliminating saturated air at an air outlet. The cooling device comprises cooling fins, a blowing type fan, a water collector, a spraying pipeline, a cooling pipe, a water collecting tank and a shell. The radiating fins, the blowing type fan, the water collector, the spraying pipeline, the cooling pipe and the water collecting tank are sequentially and horizontally arranged in the shell from top to bottom, and the cooling fins communicate with the cooling pipe. According to the closed cooling tower, the fan layout of a traditional closed cooling tower is changed, the blowing type fan serves as the cooling tower fan, the water collector is arranged at the bottomof the fan, primary condensation separation is conducted on saturated air, the cooling fins are arranged at the top of the fan, secondary absorption is conducted on heat in the saturated air, the saturated air is not saturated any more, and therefore the purpose of eliminating the saturated air is achieved. The blowing type fan is arranged below the cooling fins, cold energy generated by the blowing type fan is secondarily utilized, and energy consumption is reduced.

Description

technical field [0001] The invention belongs to the technical field of cooling towers, and in particular relates to a closed cooling tower and a method for eliminating saturated air at an air outlet. Background technique [0002] The hot and humid air reaching the outlet of the cooling tower is saturated or close to saturated. After the hot and humid air leaves the cooling tower, it mixes with the surrounding low-temperature air, and a part of the water vapor in the hot and humid air becomes liquid, forming "white smoke". [0003] The saturated air at the air outlet of the closed cooling tower not only consumes a lot of water resources, but also produces a lot of white fog in winter, which not only affects the urban landscape, but also causes the temperature in the downwind area to rise, and may cause Legionella to spread with the fog. Contents of the invention [0004] The invention provides a closed cooling tower and a method for eliminating saturated air at an air outl...
