Description

Technical Field

[0001] The invention relates to the technical field of water circulation cooling, in particular to a white smoke prevention cooling tower. Background Art

[0002] The existing water circulation cooling device includes a cooling tower, an exhaust device, a spray device, a filler and a water storage tank. The exhaust device is arranged at the top of the cooling tower, and the spray device is arranged below the exhaust device. The spray device includes a horizontally arranged spray pipe and a plurality of nozzles arranged on the spray pipe; the filler is located in the cooling tower and arranged below the spray device; the water storage tank is located in the cooling tower and arranged below the filler. When in use, the cooling water of the air conditioning equipment of the central air conditioning system flows into the spray pipe and is sprayed downward into the filler through the plurality of nozzles of the spray pipe. At this time, the cooling water sprayed through the filler forms a heat exchange with the cold air flowing through the filler and flows into the water storage tank after being cooled, and then flows back to the air conditioning equipment of the central air conditioning system through the water storage tank.

[0003] The cooling of circulating water is the result of the combined effects of three processes: evaporative heat dissipation, contact heat dissipation, and radiation heat dissipation through the contact between water and air. Evaporative heat dissipation: Water forms large and small water droplets or extremely thin water films in the cooling equipment, which expands its contact area with the air and prolongs the contact time to enhance the evaporation of water, so that the water vapor takes away the heat required for vaporization from the water, thereby cooling the water; contact heat dissipation: water contacts the air at a lower temperature, and due to the temperature difference, the heat in the hot water is transferred to the air, and the water temperature is reduced; radiation heat dissipation: the phenomenon of transmitting heat energy in the form of electromagnetic waves without the need for a heat transfer medium.

[0004] However, the above-mentioned evaporative heat dissipation transports hot water to the packing layer through a water circulation pipe, so that the hot water falls on the packing layer and then scatters and falls. At the same time, a fan is set on the top of the cooling tower body, and an air inlet is set on the side wall of the cooling tower body where the packing layer is located. External cold air is sucked in and passes through the packing layer to exchange heat and mass with water. When the air is discharged from the top of the cooling tower body, a large amount of water is taken away by the air, forming water mist outside the cooling tower. The discharged water mist will be seen as "white smoke" when the ambient temperature is low. "White smoke" not only increases the humidity around the cooling tower, but also wastes water resources.
