Application of magnetic suspension blower in sewage treatment

At present, with the improvement of sewage treatment rate requirements, major cities and factories in the country have built a large number of sewage treatment plants, in these sewage treatment plants, most of the treatment process is the use of activated sludge method of blast aeration method. Air blast aeration is the aeration equipment that sends compressed air through the pipeline into the aeration tank, disperzes into the mixed liquid in the form of bubbles, so that the oxygen in the bubbles is rapidly diffused and transferred to the mixed liquid, and supplies the microorganisms of activated sludge. Therefore, the blower has become one of the important equipment in the sewage treatment process. The energy consumption of the blower in the sewage treatment plant accounts for a large proportion of the total energy consumption, accounting for about 30% to 50% of the energy consumption of the entire sewage treatment plant. At present, the noise of the commonly used Roots fan is above 85dB, which does not meet the requirements of occupational health. It is of great significance to choose the blower with high efficiency, energy saving and low noise for the sewage treatment plant.

Magnetic suspension blower is a new type of blower, the use of active magnetic suspension bearing system, through the can control the electromagnetic force to the blower for non-contact, non-wear suspension support, so that the rotor and the impeller do not need redundant transmission links, so as to achieve the successful transmission of gas and no wear between the machine components, so that low vibration, low noise.
