Description

Technical Field

[0001] The utility model relates to the technical field of ventilation cooling towers, in particular to a device for reducing water evaporation in a mechanical ventilation cooling tower. Background Art

[0002] The oxygen circulating water pool cooling tower uses a PVC corrugated plate water collector. The water collector is an important device in the cooling tower to remove a large number of fine water droplets carried in the hot and humid air discharged from the cooling tower, avoid water mist pollution and icing in the surrounding environment, save water and protect the environment. The water collector is installed on the upper part of the cooling tower packing layer to intercept the water in the cooling tower. Its performance determines the water collection effect.

[0003] The PVC corrugated plate water collector has a low rate of water vapor escape containment, and the actual water saving rate is about 20% to 35%. The water saving rate will gradually drop to below 30% or even lower over time, causing serious evaporation losses and is not conducive to the efficient use of water resources. PVC material performance is poor, and its resistance to material strength, wet heat aging, ultraviolet aging, microbial nourishment, etc. is insufficient. The failure of the corrugated plate caused by the attenuation of the corrugated plate performance affects the related facilities such as filler, nozzle damage and pipeline blockage, which not only increases the operation and maintenance costs, but also has a direct impact on the water saving efficiency.
