Product Description
Multistage centrifugal blowers are blower equipment employing a multi-stage impeller series structure. Adjacent impellers are connected by guide vanes, belonging to the category of blade-rotation energy conversion power machinery. The air pressure range of multistage centrifugal blowers is 15kPa to 0.2MPa, with a compression ratio of 1.15-3.
Product Applications
Due to its high efficiency, stability, and smooth operation, multistage centrifugal blowers are widely used in various industrial fields such as metallurgy, chemical industry, wastewater treatment, power generation, and cement.
1. Wastewater Treatment Multistage centrifugal blowers are the mainstream equipment in the oxygen supply system of aeration tanks in wastewater treatment plants. With an air volume range of 35-220 m³/min, they can meet the requirements of activated sludge processes, providing the oxygen needed for the growth and metabolism of aerobic microorganisms, thereby decomposing organic matter in wastewater.
2. Chemical Industry In chemical production, multistage centrifugal blowers are used for gas compression, material conveying, and aeration in chemical reactions, supporting numerous chemical reactions.
3. Metallurgical Industry: Multistage centrifugal blowers are widely used in various blast furnaces and ironmaking furnaces, with working pressures exceeding 150 kPa. They also play a crucial role in sintering machine flue gas recovery and converter secondary flue gas dust removal.
4. Power Industry: In thermal power plants, multistage centrifugal blowers are used for boiler air supply and induced draft, ensuring stable boiler combustion efficiency and power generation. They are also widely used in power plant desulfurization and oxidation processes, with flow rates of 60-800 m³/min and pressure increases of 49.0-150 kPa.
5. Cement and Building Materials Industry: In cement plant production lines, multistage centrifugal blowers are used for raw material conveying, drying, and kiln combustion, ensuring continuous and efficient production. They can also be used in processes such as pneumatic conveying of fly ash.
6. Mining and Flotation: Matching coal washing jigs to improve mineral separation efficiency.
7. Food and Pharmaceutical: Cleanroom ventilation; customizable to GMP standards.
8. Textile Industry: Air supply for textile machinery such as air-jet looms and air-jet spinning machines.
9. Paper and Printing Industry, Biogas Recovery, Vacuum Dust Removal, Air Knife Drying, Galvanizing and Electroplating Processes, Liquid and Bath Oxygenation, etc.
10. Special Gas Transportation: With appropriate structural modifications, multi-stage centrifugal blowers can also be used to transport special gases such as coal gas and biogas, with an extremely wide range of applications.
