Description

Technical Field

[0001] The utility model relates to the technical field of cooling tower appliances, in particular to a trapezoidal mist elimination module. Background Art

[0002] With the expansion of the scale of coal, steel, chemical and other enterprises, the implementation of tiered water prices has led to a sharp increase in the cost of industrial water use, which has greatly increased the production costs of enterprises. In the composition of enterprise water use, industrial cooling water accounts for more than 80%, and the water demand is extremely large. Circulating cooling water is mainly consumed in the operation of the cooling tower. When the cooling tower is in use, due to the evaporation of cooling water, the hot and humid air takes away a large amount of heat and water vapor, making the hot and humid air at the outlet of the cooling tower close to saturated air. When mixed with the external environment, the temperature decreases, and the water absorption capacity of the humid air decreases, resulting in a large amount of water precipitation, forming plume fog. The plume fog phenomenon of traditional wet cooling towers is more obvious when the temperature is low in winter, especially in the north. At the same time, plume fog can cause adverse effects such as large evaporation losses and icing.

[0003] A patent CN215261274U is disclosed in the prior art. The solution includes a tower body, in which a plurality of cold air channels, a plurality of hot air channels and a plurality of demisting module groups are arranged, and the cold air channels and the hot air channels are arranged alternately; a plurality of demisting module groups are arranged side by side above the cold air channels and the hot air channels; a water receiving trough is provided between two adjacent demisting module groups, and the joint between the water receiving trough and the demisting module group is sealed with waterproof soft material and rubber and plastic; a first water conduit is connected to the water receiving trough, and the other end of the first water conduit extends into the hot air channel; the utility model can solve the problems of air leakage, water leakage and icing existing in the demisting device, improve the demisting effect, avoid equipment damage, and increase the service life.

[0004] As the existing devices including the above patents are used, the shortcomings of the technology are gradually exposed, which are mainly manifested in the following aspects:

[0005] In order to eliminate the impact of white mist in wet cooling towers on the environment and reduce the evaporation loss of circulating water, demisting and water-saving cooling towers have been widely used in recent years. However, the demisting modules in existing cooling towers are limited by their structural limitations, resulting in a small contact area with hot air, resulting in low heat exchange effect and poor demisting effect.

[0006] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
