The importance and method of cooling tower noise reduction treatment!

  In recent years, with the continuous development of the economy and the continuous development of high-rise buildings, cooling towers are generally installed on the upper floors of high-rise buildings or on terraces of 6-8 floors. The main noises are fan noise, tower vibration noise and water splashing. Noise etc. Next, I will introduce the importance of cooling tower noise treatment and related noise reduction treatment methods to the majority of netizens!MDMCooling tower noise reduction treatment manufacturer

  The importance of cooling tower noise treatment is as follows:

  Nutritionists have found that noise can also increase the consumption of essential nutrients such as vitamins, trace elements nitric acid, glutamic acid, and lysine acid in the human body, and affect health; noise can increase adrenal secretion and increase heartbeat. Increased blood pressure can easily lead to heart attacks. At the same time, noise can reduce the secretion of saliva and gastric juice and reduce gastric acid, resulting in gastric and duodenal ulcers and nausea, vomiting, stomach pain, abdominal distension, and sluggish appetite. Therefore, nowadays, people attach great importance to the treatment of cooling tower noise.MDMCooling tower noise reduction treatment manufacturer

  Under the malignant stimulus of noise, if the physiological tolerance is exceeded, it will cause damage to the central nervous system, causing the cerebral cortex to excite and inhibit the balance, which will seriously affect our sleep quality, and cause the recipient to dizziness, headache, insomnia, dreams, The symptoms of neurasthenia such as memory loss, inattention, reduced thinking ability, learning ability, and reading ability. If cooling tower noise is handled well, the above problems will not occur. The importance of cooling tower noise treatment is self-evident!MDMCooling tower noise reduction treatment manufacturer

  Cooling tower noise treatment methods are as follows:

Cooling tower noise barrier

  1. Noise reduction principle of closed cooling tower:

  The noise transmission of a closed cooling tower is mainly transmitted through three methods: air, building, and the earth, mainly air transmission. The noise reduction principle of the cooling tower is to block the propagation path of sound waves, and add a sound barrier around the cooling tower. When the sound encounters the barrier, sound reflection will occur. The greater the reflection distance, the sound will gradually weaken. The second refraction will reduce the decibel of the sound. Since water noise is different from the noise produced by fans and pumps, it is best to install the barrier in the noise area of ​​the cooling tower, which is close to the cooling tower.MDMCooling tower noise reduction treatment manufacturer

  2. Choice of noise reduction barrier for cooling tower:

  The barrier required for noise reduction in a closed cooling tower should be used according to the situation. The more common ones are brick walls, FRP and aluminum alloys. The brick wall is designed with a sand surface, and the surface has a lot of noise, which can reflect the sound at different angles, and the service life of the brick wall is very reliable. The surface of aluminum alloy and FRP is relatively smooth, so a certain curved surface should be designed. Reflect the sound downward to the greatest extent. The floating falling water energy dissipation and noise reduction device is mainly composed of plastic parts or glass steel parts (forced parts) that are formed by extrusion, injection molding or hot pressing. Its material features are light structure, easy to carry, easy to install, anti-corrosion and durable.MDMCooling tower noise reduction treatment manufacturer

  3. Noise reduction techniques for fans and water pumps:

  Fans and pumps are also the main sources of noise. The wind noise from the high-speed rotating fan is very loud. If it is only for the noise of the fan, it can be achieved by increasing the air volume and reducing the speed. Increasing the air volume can increase the arc angle of the fan page. If the budget is sufficient, you can consider directly replacing the fan with large blades and low speed to reduce noise. Or install a silencer screen at the air outlet of the water pump and fan, and the noise reduction range of the silencer screen is 20-30 decibels. The water pump can be designed with sound insulation cotton on the outside of the pump. The sound insulation cotton can effectively reduce the noise and will not affect the heat dissipation of the water pump.MDMCooling tower noise reduction treatment manufacturer
