Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cooling towers, in particular to a low-noise cooling tower with self-circulation water supplementing function. BACKGROUND

[0002] As an indispensable heat exchange equipment in industrial production and civil buildings, the core function of the cooling tower is to dissipate the waste heat in the industrial circulating water or air conditioning system to the atmosphere through the heat exchange process of gas-liquid contact, so as to realize the cooling circulation of the heat exchange medium, guarantee the stable operation of the subsequent production process or the comfort of the indoor environment. With the scale development of modern industry and the continuous improvement of environmental protection and energy saving requirements, the application scenarios of the cooling tower have been extended to power, chemical, metallurgical, electronic, building heating and ventilation and other fields. Its operation performance, energy consumption level and environmental friendliness have become the key indicators to measure the value of the equipment.

[0003] However, the existing cooling tower still has some defects when in use. For example, the water circulation cooling tower disclosed in application No. CN202021002677.6 includes a tower body, ventilation openings are formed on both sides of the tower body, an exhaust opening is fixedly installed on the top of the tower body, a fan is fixedly installed inside the exhaust opening, two isolation nets are fixedly installed inside the tower body, the isolation nets and one side of the tower body ventilation opening are filled with fillers, and a water tank is fixedly installed on the top of the fillers. The water circulation cooling tower uses the water adding assembly to draw the water in the water tank into the water tank, and then the water flows through the water tank and drips onto the fillers. In this way, the fillers are wetted. The fan operates to drive the airflow to enter the ventilation opening of the tower body, and the water vapor on the fillers is carried away by the fillers and discharged. In this way, the temperature is reduced by using the water vapor to achieve the purpose of cooling. The water flows from the fillers and collects at the bottom of the tower body, and then flows into the water tank through the metal mesh plate. In this way, the water can be recycled. However, the following problems still exist in the actual use process. During the exhaust process, a large amount of liquid water that has not been fully evaporated is entrained in the water vapor discharged from the exhaust opening. These liquid waters are directly discharged into the atmosphere without being recycled, which reduces the water recycling rate of the equipment and causes a considerable loss of water resources. When the fan at the exhaust opening operates at a high speed, the motor itself will produce mechanical vibration noise, and the high-speed friction between the fan blades and the air will form high-frequency aerodynamic noise. These noises have a wide range of propagation. If the equipment is installed near residential areas or office areas, it will cause significant noise interference to the surrounding environment and personnel. In view of the above problems, the present application is developed after in-depth research.

[0004] In view of the above problems, the present application is developed after in-depth research. SUMMARY
