Industry Application Analysis of Multistage Centrifugal Blowers

Multistage centrifugal blowers play a pivotal role in the industrial sector due to their high-pressure, efficient, and low-noise attributes, with their applications spanning multiple key industries:

I. Sewage Treatment and Environmental Engineering

In the field of sewage treatment, multistage centrifugal blowers serve as the core equipment for oxygen supply in aeration tanks. By delivering high-pressure air, they promote the decomposition of organic matter by aerobic microorganisms, thereby enhancing treatment efficiency.

 For instance, after adopting this equipment, a large-scale sewage treatment plant maintained a stable dissolved oxygen concentration of 2-4mg/L in its aeration tanks, resulting in a 30% increase in the efficiency of the activated sludge process. Additionally, in desulfurization and denitrification projects, their high-pressure air supply capability meets the demands of oxidation reactions, facilitating compliant emission of exhaust gases.

II. Metallurgical and Energy Industries

The metallurgical industry represents a significant application scenario for multistage centrifugal blowers. During blast furnace air supply, the equipment can provide pressures exceeding 150kPa, ensuring thorough combustion within the furnace.

 A steel enterprise reported a 12% increase in blast furnace production capacity and an 8% reduction in energy consumption per ton of iron after adopting the equipment. In the power sector, these blowers are employed for boiler induced draft and pulverized coal ash pneumatic conveying. A thermal power plant optimized its air supply system using this equipment, resulting in annual savings exceeding one million yuan in coal costs.

III. Chemical and Material Processing Industries

In the chemical sector, multistage centrifugal blowers support high-pressure reactions such as ammonia synthesis and petroleum cracking, with certain models capable of withstanding corrosive media.

 For example, a petrochemical enterprise utilized a corrosion-resistant model to convey chlorine gas, achieving over 20,000 hours of continuous trouble-free operation. In mineral flotation processes, their stable air pressure enhances mineral separation efficiency. A coal washery reported a 5 percentage point increase in clean coal recovery rate after implementation.

IV. Food and Pharmaceutical Industries

In food processing, multistage centrifugal blowers are utilized for ventilation, drying, and exhaust gas treatment, complying with GMP standards. A traditional Chinese medicine enterprise reported a 20% increase in extract processing efficiency and achieved a 100,000-grade cleanliness level in workshop air after adopting the equipment. In the pharmaceutical sector, their oil-free operation prevents cross-contamination, making them the preferred choice for ventilation in clean rooms.
