Description

Cooling tower with sewage filtering mechanism

Technical Field

The utility model relates to the technical field of cooling towers, in particular to a cooling tower with a sewage filtering mechanism.

Background

A cooling tower is a device for cooling water, wherein the water exchanges heat and mass with air flowing through the cooling tower, so that the water temperature is reduced; it is widely applied to air-conditioning circulating water systems and industrial circulating water systems.

In the circulating water system, various impurities are usually generated in the water due to actual use, and the existence of the impurities can influence the circulating use of the water.

Therefore, a filtering mechanism is usually arranged in the cooling tower, and filtering materials such as bamboo charcoal, ceramic particles and the like are usually adopted for filtering impurities in water, but because the cross section of the cooling tower is large, namely the area of the filtering materials is too large, water flows in a directional manner easily, partial filtering materials are saturated easily, and other filtering materials are not saturated.

The technical principle of the utility model is as follows: in the falling process of the sewage to be cooled through the spraying device, the exhaust fan plays a role in cooling, and when the sewage enters the filtering material layer, if the protrusions face upwards, the sewage can be concentrated at the edge position to drop; when sewage enters the filtering material layer, if the protrusions face downwards, the sewage can be concentrated in the center position to drip, so that the paths of the filtering material layers opposite to the protrusions are all inclined lines, namely the passing filtering distance is larger, and the filtering effect is better.

And the whole area of the filtering material flow layer can be filtered more easily, partial areas can not appear, and the filtered water is less, even the technical problem that the sewage does not pass through.
