Sewage treatment fans are also called sewage treatment blowers. Their main functions are as follows
1. It refers to the aeration of oxygen required by microorganisms in the environmentally friendly water treatment biological contact oxidation process through the sewage treatment fans. Supply, which is characterized by setting fillers in the pool, aeration at the bottom of the pool to oxygenate the sewage, and keeping the sewage in the pool in a flowing state.
2. Ensure that the sewage is fully in contact with the filler immersed in the sewage, and avoid the defect of uneven contact between the sewage and the filler in the biological contact oxidation tank. We call the blower with this function a sewage treatment fan.
Several types of commonly used fans
1. Roots blower. If the load requires a constant flow effect, use a Roots blower. Because the Roots blower is a constant flow fan, the main working parameter is the air volume. The output pressure changes with changes in the pipe and load, and the air volume changes very little. Roots blower is a high-pressure blower. Roots blower is a volumetric blower. The air volume delivered is proportional to the number of revolutions. It transports gas from the suction side to the discharge side.
2. Centrifugal fan. If the load requires a constant pressure effect, use a centrifugal fan. Because the centrifugal fan is a constant pressure fan, the main working parameter is wind pressure. The output air volume changes with changes in the pipe and load, but the wind pressure does not change much. Centrifugal fans have low wind pressure. The compression process of air is usually carried out through several working impellers (or stages) under the action of centrifugal force. Centrifugal fans have square torque characteristics, while Roots blowers basically have constant torque characteristics.
3. Rotary fan. Roots blowers generally have relatively large air volume and high pressure. Roots blowers are also very noisy. If the air volume is relatively small and the noise requirements are relatively high, choose a rotary blower. Rotary blowers are also constant flow fans. , the main working parameter is the air volume, the output pressure changes with the change of the pipe and load, the air volume changes very little, the rotary fan is a variable volume compression, its main characteristics are: low speed, low noise, low vibration, high efficiency, High energy saving.
