Maglev Centrifugal Turbo Blower for Paper Mill Wastewater Treatment

      When the wastewater treatment process uses the activated sludge process, the aeration blower is one of the core equipment of the treatment process.
       Energy costs of wastewater treatment plants account for 40% to 80% of their operation and maintenance costs, of which the energy consumption of the blower in the aeration and oxygenation process accounts for a large proportion of the total energy consumption, accounting for 50% to 60% of the energy consumption of the entire wastewater treatment plant, so the energy efficiency of the blower will play a crucial role in the level of energy consumption and operating costs of the wastewater treatment plant.
      In addition, the aeration blowers used in wastewater treatment plants at home and abroad mainly include Roots blowers, multi-stage centrifugal blowers, single-stage high-speed centrifugal blowers with gear speed increase, air suspension centrifugal blowers and maglev centrifugal blowers. Among them, Roots blowers and multi-stage centrifugal blowers are gradually eliminated in foreign wastewater treatment plants due to their low efficiency, high noise, high energy consumption, large volume and weight, and poor flow regulation performance and other defects. The Maglev centrifugal blower belongs to the latest form of single-stage high-speed centrifugal blower, which adopts advanced technology of frequency conversion and maglev bearing, eliminates the gear speed increment component and lubrication system of traditional single-stage high-speed centrifugal blower, and meets the requirements of wastewater treatment plant for aeration blower such as energy saving, environmental protection, wide range of air volume adjustment, low noise, low vibration and low maintenance cost.

--Energy saving and high efficiency: integrated magnetic suspension bearing, high speed permanent magnet synchronous motor, high efficiency flow parts, special control system and a series of advanced technologies, high efficiency and energy saving of the whole machine.Compared with traditional Roots blower, the efficiency is increased by 30%~40%.Taking 160kW maglev blower as an example, each one can save more than 500,000 degrees of electricity per year compared with the traditional Roots blower, and the cost can be recovered in about 1 to 2 years.
--Low noise and vibration: Thanks to maglev bearing technology, there is no mechanical contact and friction between rotating parts and stationary parts in the fan. The vibration of the fan operation is very small, and the noise does not exceed 80 dB.
--Small size, light weight: The whole machine integrated design, internal integrated fluid components, motor, frequency converter and other components, compact structure, light weight.
--Intelligent operation and maintenance: The use of advanced control system, a variety of control modes can be selected. The operating platform can be monitored in real time without special person on site duty. Fully enclosed air cooling and water cooling systems are used to dissipate heat from the motor to ensure stable and efficient operation of the fan. Modular design, convenient maintenance.
--Very Low maintenance cost: Using magnetic bearing technology, completely frictionless. No gear box, lubrication system and other parts in the system, no mechanical maintenance, reduce the chance of damage, service life can reach more than 20 years. Daily maintenance only need to replace the air filter, save lubricating oil, cleaning costs, convenient and fast.
