At present, the emergence of air turbo blowers to replace Roots blowers is more common. In general, the energy consumption of sewage plants accounts for 50%-80% of the cost of the whole plant, and excessive energy consumption often hinders the management and upgrading of sewage treatment plants, and even makes it difficult for some small and medium-sized sewage plants to operate normally. Therefore, in the past, energy conservation and consumption reduction were in order to save money for their own sewage plants. In the traditional sewage treatment blast aeration, the use of Roots blowers and multi-stage centrifugal blowers, such blower technology is old, belongs to the last century technology, equipment failure rate is high, the need for lubricating oil maintenance, high noise is bad for environmental protection, easy to cause complaints from surrounding residents. The high energy consumption of such blowers often pushes up the operating costs of the factory and lowers the company's business revenue, which requires the use of new blowers to replace the traditional Roots blowers and multi-stage centrifugal blowers.

Air turbo blower has the advantages of high efficiency, low energy consumption, low noise, small model, easy installation, less maintenance work and so on. A 300kw air turbo blower saves energy about 30% compared with Roots blower, and saves electricity about 930,000 yuan annually, which has obvious energy-saving effect and economic benefits, and has a wide range of application prospects in the field of sewage treatment.

The air turbo blower uses a high-speed direct motor, which is fundamentally different from the conventional blower that relies on the form of gear growth, greatly reducing the energy consumption caused by mechanical transmission and mechanical friction, and improving the efficiency. It relies on the air force field to levitate the bearing and maintain high-speed operation, which is different from traditional roller bearings. There is no physical contact point between the rotating shaft and the bearing during operation, so no lubricating oil is required and the energy loss is low. The speed of motor is adjusted by inverter to adjust the air volume, with high precision. The cooling method is air inlet and self-cooling. In short, the air turbo blower has the characteristics of high efficiency, energy saving, low noise, reliable operation and long-term maintenance, and is suitable for use in large and medium-sized sewage treatment plants.
