Blower noise reduction
Blower noise includes aerodynamic noise, aerodynamic noise, mechanical noise, electromagnetic noise, and structural noise. The strongest of these is aerodynamic noise, followed by mechanical noise and electromagnetic noise. According to the size of the blower noise , site conditions, and noise control requirements, the optional noise control measures include: installing a muffler, installing a sound insulation cover, sound absorption, sound insulation, vibration reduction, and vibration isolation.
1. The noise of the casing and the motor can be solved by installing a sound insulation cover, and the sound absorption and sound insulation processing is performed in the fan room.
2. Install a muffler outside the air inlet and outlet of the blower, with built-in muffler inserts, to reduce noise when passing through a specially constructed muffler. The muffler is an effective measure to reduce the radiation of air intake and exhaust ports of air power equipment or to transmit noise along the pipe.
3. The fan is suspended by a damping spring hanger shock absorber.
Blower noise reduction can be designed in accordance with factors such as the sound source object, noise characteristics, noise reduction requirements, process conditions, and installation location to ensure a good noise reduction effect.
Selection of tunnel fan and calculation of air volume
With the continuous development of scientific skills, everyone's demand for the use of tunnel fans is getting higher and higher. As far as the current development trend of tunnel fan skills abroad, it will be developed in the direction of tunnel fans with low noise. The noise of tunnel fans is one of the most important sources of noise pollution in industrial production. Larger and faster tunnel fans make the noise question outstanding. For low-frequency noise, the tunnel fan is mainly improved by the structural design of the tunnel fan, the price of the blower, and the noise of the body is reduced. If it fails to meet the requirements, measures such as installing a muffler soundproof room can be adopted. To sum up, these skills are not only the development trend of foreign tunnel fans in the future, but also the best efforts of domestic tunnel fan profession in terms of skills.
The definition of the wind volume of the tunnel fan is the product of the wind speed V and the cross-sectional area F of the wind tunnel. Since large tunnel fans can accurately measure the wind speed with an anemometer, the calculation of the wind volume is also very simple. You can directly calculate the air volume by using the formula Q = VF. The number of tunnel fans is determined based on the number of air changes in the selected room, the total air volume required by the plant is calculated, and the number of tunnel fans is calculated. Calculation formula: N = V × n / Q In the meantime: N——the number of tunnel fans (set); V——the volume of the site (m3); n——the number of ventilations (times / hour); Q——the selected tunnel fan Type of single air volume (m3 / h). The selection of the type of tunnel fan is probably based on the actual situation of the plant. Try to choose the type of tunnel fan that matches the original window size. The tunnel fan and the wet curtain must be as far as possible from each other (as far as possible from the two sides of the gable installed in the plant). Outstanding ventilation. The exhaust side should be as close as possible to the neighboring buildings to avoid affecting nearby residents. If the air taken out from the room contains a polluted environment, which is the best blower manufacturer, it can spray water equipment at the air outlet, collect the nearby pollutants and collect them, without polluting the environment, and achieve the purpose of energy saving.
