Description

Technical Field

[0001] The utility model relates to the technical field of air separation, in particular to a demisting and water-saving cooling tower. Background Art

[0002] In the operation of traditional cooling towers, cold air exchanges heat with water inside the cooling tower to generate saturated hot and humid air.

With the increasing shortage of water resources today, water conservation is particularly urgent; at the same time, the existence of fog affects the surrounding environment; the chemical agents in the steam of the cooling tower also cause corrosion to the surrounding equipment.

[0017] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the present invention is described in detail below with reference to the embodiments.

[0018] Figure 1 Shown is a schematic structural diagram of a fog-eliminating and water-saving cooling tower according to an embodiment of the utility model. Figure 2 Shown Figure 1 A schematic diagram of the arrangement of the water runoff plate in the illustrated embodiment. Figure 3 Shown Figure 1 A schematic top view of the water runoff plate in the illustrated embodiment.

[0019] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a defogging water-saving cooling tower 100, including an air path and a water path. The air path includes an air inlet 21, which is connected to an air inlet main pipe 22. The air inlet 21 and the air inlet main pipe 22 are arranged at the lower part of the defogging water-saving cooling tower 100, and a plurality of air pipes 23 extending vertically are separated from the air inlet main pipe 22. The air pipes 23 are upwardly merged into the air outlet main pipe 24 and flow out through the air outlet 25. The water path includes a water inlet 11, which is arranged at the upper part of the defogging water-saving cooling tower 100, and a plurality of water runners 12 are distributed inside the defogging water-saving cooling tower 100. The plurality of water runners 12 are arranged in an inclined manner in a staggered manner to form a zigzag distribution. The plurality of air runners 23 pass through the plurality of water runners 12, and a water trough 14 is arranged below the plurality of water runners 12, and a water outlet 15 is arranged on the water trough 14.

[0020] In the embodiment of the utility model, cold air enters from the air inlet 21 and enters the air duct 23 via the air intake manifold 22. The air duct 23 passes through a plurality of water ducts 12, thereby absorbing the heat of the water flowing through the water ducts 12. Figure 1 and Figure 2 As shown, the solid arrow indicates the direction of water flow, and the hollow arrow indicates the direction of air flow. Water enters from the water inlet 11 and falls on the water running board 12. A plurality of water running boards 12 are arranged obliquely and staggered to form a zigzag path, so that the water on the water running board 12 flows along the zigzag path under the action of gravity. A plurality of air running pipes 23 pass through the water running board 12, and the air flowing in the air running pipe 23 takes away the heat of the water, thereby cooling the hot water. In the process of heat exchange, the air will not contact with the water, thereby will not take away the water mist, and will not lose water. Moreover, the water does not flow in the pipeline, but flows on the water running board 12, and there is no problem of pipeline blockage, and it is easy to maintain.

[0021] The cross-sectional shape of the mist-eliminating water-saving cooling tower can be circular or square. Figure 3 (a) shows the case where the cross-section of the mist-eliminating water-saving cooling tower is square. Figure 3 (b) shows the case where the cross-section of the mist-eliminating water-saving cooling tower is circular. The plurality of water-flowing plates 12 are sealedly connected to the inner wall of the mist-eliminating water-saving cooling tower so that water can flow on the water-flowing plates 12. Figure 3 As shown, the plurality of air pipes 23 are distributed in an array on the water running board 12, and the air pipes 23 in different rows are staggered, thereby increasing the chances of water flowing on the water running board 12 contacting the air pipes 23 and promoting heat exchange. To promote heat exchange, the water running board 12 and the air pipes 23 are made of heat conductive material.

[0022] The utility model provides a mist-eliminating and water-saving cooling tower in which water and air do not come into direct contact, so that water mist will not be generated and water will not be carried away, thereby saving water resources; meanwhile, the utility model is not prone to pipeline blockage and is easy to maintain.
