Description

Technical Field

[0001] The utility model relates to the technical field of cooling tower tools, in particular to a cooling tower drip loss measuring device. Background Art

[0002] In modern large-scale thermal power station projects, natural ventilation cooling towers or mechanical ventilation cooling towers use water as the circulating coolant, and discharge the heat absorbed from the return water of the condenser circulating water system into the atmosphere to achieve the purpose of lowering the water temperature.

[0003] During the normal operation of the cooling tower, drip loss will occur. The drip loss water volume generally refers to the amount of water carried away by the air in the form of water droplets at the water outlet of the cooling tower duct, and also includes the loss part of the water droplets falling on the filler and splashing outside the cooling tower. When the drip loss rate is high, the cooling tower replenishes a lot of water, and some of the cooled water droplets are carried away, which will cause the loss and decrease of the effective heat exchange rate. Therefore, strictly controlling the drip loss rate of the cooling tower is an important means of saving water. To achieve this goal, the drip loss rate of the cooling tower must be accurately measured first. Only by accurately measuring this value can the improvement of the cooling tower structure be effectively guided, and then more energy-saving cooling tower products can be developed.
