With the rapid development of environmental protection industry, the requirement of environmental water treatment is becoming higher and higher. Especially in the core component of sewage treatment - aeration equipment, Roots blower operation noise requirements are also increasing. In order to avoid secondary pollution - noise pollution of aeration blower. Low noise aerated Roots blower came into being at the historic moment.
In fact, low noise is only relative, such as Shaanxi sewage treatment Roots blower, the current use of three-leaf Roots blower compared to the previous use of two-leaf Roots blower noise reduction by 20% - 30%, known as low noise Roots blower, of course, different manufacturers, different quality of fans, Roots blower noise is also different.
For example, the noise range of Roots blower with 3.46 m3/min air volume is 75-80 dB.
In order to meet the requirements of low noise of Roots fans for water treatment, there are low noise rotary fans and silent liquid ring fans for customers to choose. These two fans are identical in use with Roots fans for sewage treatment in Shaanxi Province. Because they are different in design principle and use mode from Roots fans, the operation noise is greatly reduced. Rotary fan with the same technical parameters, air volume 3.25 m3/min, operating noise range 63-69 decibels. The noise of the liquid-ring fan with the same technical parameter of 3.78 m3/min is only about 60 dB. From this we can see that the low noise fan is only relative, and the silent fan is only relative to the low noise fan. Of course, when customers choose the aeration blower, they should take other factors into account, such as the cost of the blower, operating costs, follow-up maintenance and so on.
