Noise is one of the main environmental pollutants, which hinders people's conversation, thinking, and learning, and creates unpleasant feelings. So what are the main sources of noise?

(1) Reduce noise in the transmission path, control the propagation of noise, change the propagation path of noise already emitted by the sound source, such as adopting measures such as sound absorption, sound insulation, sound barriers, vibration isolation, and reasonable planning of urban and building layout.

(2) To reduce the noise of the sound source, the industrial and transportation industries can choose low-noise production equipment and improve production processes, or change the movement mode of the noise source (such as using damping, isolation and other measures to reduce the vibration of solid sound sources).

(3) When measures cannot be taken for noise protection of the listener or listener in terms of the sound source and propagation path, or when the acoustic measures taken still cannot achieve the expected effect, protective measures need to be taken for the listener or listener. For example, workers exposed to long-term occupational noise can wear ear plugs, earmuffs, or headgearCooling tower air duct,

In the circulating water system, the cooling tower is an important equipment, and there are many factors that affect the thermal performance of the cooling tower, one of which is the air volume of the fan. If the kinetic energy loss at the air outlet is small, the ventilation volume of the cooling tower will be large, and the thermal performance of the cooling tower will be high.

The air duct of the cooling tower has four main functions, one is to maintain the structure of the fan; The second is the guarantee structure for air volume and pressure; The third is to ensure the introduction of humid and hot air into the atmosphere to reduce backflow and improve the efficiency of the cooling tower workbench; The fourth function is to act as a noise reduction function that blocks the propagation path of noise and dampens the consumption of sound energy.

The early air ducts were low angle suction air ducts, which are still used by many manufacturers. Their disadvantages are high ventilation resistance and high kinetic energy consumption; The second generation of air ducts is a diffusion type kinetic energy recovery type with an inclination angle of 11.5 degrees, and the suction inlet adopts a streamlined design A diffusion section has been added above the rotating surface of the fan blades, which can reduce the wind speed at the air outlet and decrease the dynamic pressure of humid and hot air entering the atmosphere. This means reducing the total pressure of the fan and minimizing energy input.

By measuring and setting up the cooling tower, obtaining on-site data, analyzing the reasons for the vibration of the air duct, and further simulating the cooling tower air duct through computer modeling. During the production process of the air duct, strengthen the weak links of the air duct, and avoid the natural frequency of the cooling tower fan and the natural frequency of the air duct being in the same resonance range during the selection process of the cooling tower. The kinetic energy recovery type air duct produced effectively avoids the vibration phenomenon of the cooling tower air duct.
