Roots blower is also the core electromechanical equipment necessary for sewage treatment aeration tank

Roots blower not only has reasonable structure, high pressure rise, high efficiency, large air volume, low noise, stable operation, excellent performance, long service life, simple maintenance and other characteristics. The following is an introduction to the importance of Roots blower in the aeration process.

In addition, Roots blower is also the core electromechanical equipment necessary for sewage treatment aeration tank. The effect and energy consumption are directly determined. The working energy consumption of Roots blower accounts for a large part of the energy consumption of the whole sewage treatment. The biological sewage treatment process mainly uses roots blower to increase oxygen in the aeration tank, promote the growth of aerobic microorganisms, and achieve sewage treatment by metabolizing and decomposing suspended solids, dissolved organic matter, nitrogen, phosphorus and other nutrients in the sewage. The purpose is to become one of the important equipment of the sewage treatment plant.

Roots blower According to the theory of fluid mechanics, gas flow will be accompanied by loss. For example, after the gas flows through the throttling device, the pressure of the gas flow decreases accordingly, that is, they lose the useful work of the fan. Roots blower is attributed to the fact that the fan is conveying gas, which is a waste of fan energy.

The working point of the fan is the intersection of the performance curve of the fan at * * * speed and the resistance characteristic line of the pipe network. It does not always stay at the design point. It will change with the change of user demand or external conditions, that is, the fan actually works under different conditions. In order to make the fan's air pressure or air volume reach the target value, the fan or pipe network must be manually controlled, also known as regulation. Through adjustment, it is necessary to meet the requirements of production flow or pressure, and save energy greatly under the condition of stable operation of fans. In short, the purpose of supervision is to meet performance requirements, expand (stabilize) conditions, achieve energy conservation and prevent surges.
