Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, and more specifically to a demisting cooling tower with a demisting structure. Background Art

[0002] Cooling towers use evaporative cooling technology to remove a large amount of heat from circulating water. Generally, cooling towers are divided into open cooling towers and closed cooling towers. Compared with open cooling towers, the industrial medium of closed cooling towers flows in the coils, which prevents the industrial medium from being polluted by spray cooling water and air, thereby keeping the industrial medium clean. However, like open cooling towers, the evaporation loss of spray cooling water in closed cooling towers is huge and cannot be ignored. At the same time, the concentration of spray water evaporates and increases continuously, resulting in serious scaling on the surface of the coils, which is not conducive to heat exchange; on the other hand, the large amount of evaporation of spray water leads to high humidity in the outlet air, and white fog is likely to appear on the top of the tower, causing serious impact on the surrounding areas. Therefore, it is necessary to study the water-saving and fog-eliminating of closed cooling towers.

[0003] The utility model patent with patent publication number CN220602251U discloses a new type of condensing defogging cooling tower, including a tower body, and also including a cold water pool, filler, spray device, water collector, condensing device, mixing chamber and fan arranged in the tower body from bottom to top; the condensing device includes multiple groups of condensing modules arranged horizontally, and the condensing module includes a steel structure frame and a plurality of stacked condensing plates arranged in the steel structure frame; a corrugated guide structure is arranged on the condensing plate, which can facilitate the rapid outflow of condensed water and reduce the thickness of the liquid film, and the corrugated guide structure is a vertical corrugated structure with a guide groove or a cross corrugated structure with a guide groove. The condensing plate of the utility model adopts a corrugated arrangement, which can increase the heat exchange area, and the guide groove is arranged on the condensing plate, which can collect the condensed water in the entire wet and hot channel and fully countercurrent heat exchange it with the wet and hot air, thereby improving the heat exchange capacity and reducing the thermal resistance at the same time, achieving good effects of defogging and water saving.

[0004] However, in actual use, since the condenser, water collector and other structures for demisting are installed inside the tower body and at the bottom of the fan, it is easy to cause wind direction obstruction, thereby reducing the exhaust flow rate, which can easily lead to poor cooling effect. Therefore, a demisting cooling tower with a demisting structure is proposed. Utility Model Content

The spray plate sprays cold water into the tower body, thereby performing liquid cooling, so that the incoming hot air is cooled by the cooperation of air cooling and liquid cooling. The cooled gas is discharged from the exhaust pipe, and after entering the exhaust pipe, it is cooled twice by the condensation component, so that the water vapor mixed in the gas is adsorbed on the condensation component to achieve the defogging effect. The moisture adsorbed on the condensation component is squeezed out of the condensation component into the liquid receiving bucket under the operation of the scraping mechanism, and then discharged into the water tank from the drainage pipe at the bottom of the liquid receiving bucket for recycling. At the same time, the water sprayed from the spray plate falls into the bottom of the tower body, and then enters the water tank from the outlet pipe for recycling.

[0018] Technical effects and advantages of the utility model:

[0019] 1. Through the arrangement of the cold liquid pipe, the filter plate and the absorbent cotton, compared with the prior art, the cooling water drawn by the water pump enters the cold liquid pipe, so that the cold liquid pipe is at a lower temperature, so that when the gas inside the tower body is discharged, a secondary cooling effect can be achieved, and the moisture in the gas can be absorbed under the adsorption and filtration of the absorbent cotton installed on the filter plate, so as to achieve the defogging effect, and one end of the cold liquid pipe is connected to the water pump and the other end is connected to the spray plate, so that the condensed water cooled by the condenser can be reasonably used, thereby reducing the use of condensation equipment and reducing manufacturing costs;

[0030] In a specific implementation, the blower 3 blows air from the wind box 2 into the tower body 1 during the process of hot air entering from the air inlet 4, thereby increasing the air flow inside the tower body 1 and improving the cooling effect. During the air cooling process, the water pump 11 draws water from the water tank 5 into the condenser 10 for condensation, and then inputs it into the condensation component 15, and then discharges it from the condensation component 15 into the spray plate 6.

The water adsorbed on the condensation component 15 is squeezed out of the condensation component 15 into the liquid receiving bucket 13 under the operation of the scraping mechanism 9, and then discharged into the water tank 5 from the drainage pipe 14 at the bottom of the liquid receiving bucket 13 for recycling. At the same time, the water sprayed from the spray plate 6 falls into the bottom of the tower body 1, and then enters the water tank 5 from the water outlet pipe for recycling.

[0032] During specific implementation, the liquid receiving bucket 13 can receive the water squeezed out of the condensation component 15, and discharge it into the water tank 5 under the connection of the drain pipe 14 for recycling, thereby reducing the waste of water resources. At the same time, since the water has just been cooled down by the condensation component 15, it can be conducted with the water temperature in the water tank 5, thereby also having the effect of cooling the water temperature in the water tank 5, so that the condenser 10 can quickly cool the extracted water to an appropriate temperature to save electricity.
