Multi stage centrifugal blowers are widely used in the following industrial fields due to their high pressure, high efficiency, and stable operating characteristics:
1、 Core application industry
Metallurgical industry
Used for blast furnace blowing, sintering machine flue gas recovery, and converter secondary flue gas dust removal, with a working pressure of over 150kPa.
Typical case: Yunnan metallurgical enterprises adopt magnetic levitation centrifugal blowers instead of screw air compressors, with a power saving rate of 47.6% and an annual electricity cost savings of 764000 yuan.
Chemical and petroleum industries
Stable gas power is provided in high-pressure reactions such as synthetic ammonia and petroleum cracking, and some models can withstand corrosive media.
The transportation of coke oven gas adopts multi-stage centrifugal fans, combined with labyrinth seals to reduce the risk of leakage.
Wastewater treatment
The mainstream equipment of the aeration tank oxygen supply system has an air flow range of 35-220m 3/min, which meets the requirements of the activated sludge process.
2、 Expand application scenarios
Electricity and cement: boiler induced draft, fly ash pneumatic conveying.
Food and pharmaceuticals: Clean room ventilation (in compliance with GMP standards), such as the treatment of traditional Chinese medicine extracts.
Mining and flotation: Matching coal washing jigs to improve mineral separation efficiency.
3、 Comparison of Technical Advantages
Energy saving: Compared to the Roots blower, it saves 30% energy, and the magnetic levitation model further reduces energy consumption.
Adaptability: Customizable explosion-proof or corrosion-resistant versions, suitable for complex working conditions.
