Energy consumption optimization strategy of Roots blower in wastewater treatment

Roots blower is a positive pressure wind conveying device, widely used in the industrial field of waste water treatment system, its basic principle is through the gap between the rotor, the air is inhaled and compressed through the impeller, so as to form a high pressure air flow, supply to the various parts of the waste water treatment system. This structure makes the Roots blower have the characteristics of continuous gas transmission, no oil pollution, low noise, etc.


Although Roots blowers play an important role in wastewater treatment systems, they consume a lot of energy. Therefore, in order to reduce operating costs, reduce environmental pollution and improve the overall efficiency of wastewater treatment system, it is necessary to optimize the energy consumption of Roots blower.



1. Regular maintenance and maintenance: Roots blower will accumulate impurities such as dust and oil after a long time of operation, resulting in increased resistance, thereby increasing energy consumption. Regular cleaning and lubrication of the rotating parts of Roots blowers can effectively reduce friction losses and improve the efficiency of the rotor, thereby reducing energy consumption.


2. Use frequency conversion control technology: traditional Roots blowers usually work at a constant speed, and the airflow demand of wastewater treatment systems is uneven. By introducing frequency conversion control technology, the running speed of Roots blower can be adjusted according to actual needs to avoid excess air and energy waste.


3. Optimize the system design: rationally plan the layout of the wastewater treatment system and the position of Roots blower, install the blower closer to the consumption point, shorten the length of the pipeline, reduce the transmission resistance, and reduce energy consumption.


4. Adopt efficient and energy-saving Roots blowers: The development of modern technology makes the new generation of Roots blowers have higher efficiency and lower energy consumption. Selecting the efficient and energy-saving Roots blower suitable for the needs of the wastewater treatment system can reduce energy consumption while ensuring the normal operation of the system.
