What are the application scenarios of magnetic levitation blower?

Depth Analysis of Core Application Scene of Magnetic Levitation Blower

Magnetic suspension blower, as an upgraded alternative product of traditional Roots blower and centrifugal blower, has the core advantages of energy saving, high efficiency (30%-40% energy saving compared with traditional blower), low noise and environmental protection (operating noise ≤85dB), convenient operation and maintenance, long service life and so on, and has been widely used in many fields such as environmental protection, industrial production, municipal engineering, etc., and has become a green and low-carbon development of various industries. The following is a detailed explanation from the core application scenarios:

I. Environmental protection water treatment field (core mainstream application scenario)

In the aeration system of sewage treatment plants and industrial wastewater treatment stations, magnetic levitation blower is the core equipment, and its application covers the aerobic treatment of municipal sewage and industrial wastewater (chemical industry, printing and dyeing, paper making, food processing, etc.). Aerobic biochemical treatment needs to continuously deliver air to the reaction tank to provide sufficient oxygen for microbial degradation of organic pollutants. Traditional Roots blower has pain points such as high energy consumption, loud noise and frequent maintenance, while magnetic suspension blower can adjust its operating parameters (air volume range of 10-1000 m/min, air pressure of 0.3-1.2bar) in real time according to dissolved oxygen concentration in the tank, ensuring uniform and efficient aeration and greatly reducing energy consumption at the same time-a municipal government In addition, in the sludge treatment process, the magnetic suspension blower can be used for aerobic digestion of sludge and aeration and ventilation of sludge drying, and its stable wind pressure output can ensure the efficiency of sludge treatment, and the oil-free lubrication design avoids the secondary pollution of sludge by oil pollution, which meets the high standard requirements of environmental protection treatment.

Second, the municipal and building ventilation field

Magnetic levitation blower plays a key role in the ventilation and smoke exhaust system of urban rail transit (subway, light rail). The public areas of subway tunnels and stations need continuous ventilation to ensure indoor air quality and personnel safety. In case of fire and other emergencies, it is necessary to quickly switch to smoke exhaust mode, which requires the fans to have the characteristics of rapid response and stable wind pressure. The start-up time of the magnetic suspension blower is short (≤30 seconds), and the variable frequency system can realize the stepless adjustment of the air volume of 0-100%, which meets the dual requirements of normal ventilation and emergency smoke exhaust, and the low noise advantage can reduce the impact on the surrounding environment and adapt to noise-sensitive public scenes such as subways. In addition, in large-scale commercial complexes, office buildings, data centers and other buildings, magnetic levitation blowers can be used for fresh air delivery, exhaust ventilation and cooling ventilation of computer rooms in central air-conditioning systems, and their high-efficiency and energy-saving characteristics can reduce building energy consumption. Intelligent control systems can be linked with building automatic control systems to realize unattended operation and improve operation and maintenance efficiency.

Third, the field of industrial production technology

(1) Chemical and petrochemical industries

In chemical production, magnetic suspension blower is widely used in gas transportation, fermentation aeration, desulfurization and denitrification and other processes. For example, in the production of synthetic ammonia, methanol and other chemical products, hydrogen, nitrogen and other process gases need to be transported into the reaction kettle. The oil-free lubrication design of the magnetic suspension blower can avoid oil pollution to the process medium and ensure the purity of the products. In the biological fermentation process (such as the production of antibiotics and amino acids), it is necessary to accurately control the aeration air volume and air pressure to provide a suitable environment for microbial growth, and its high-precision adjustment ability can improve fermentation efficiency and product yield. In addition, in the flue gas desulfurization and denitrification system of petrochemical industry, the magnetic suspension blower is used to transport desulfurization and denitrification agents (such as limestone slurry atomized air and ammonia diluted air), and its stable wind pressure output can ensure the full desulfurization and denitrification reaction and help enterprises achieve environmental protection emission standards.

(2) Food and pharmaceutical industries

Food processing and pharmaceutical production require extremely high cleanliness of production environment and medium purity, and the oil-free operation characteristics of magnetic suspension blower make it an ideal choice. In food fermentation (beer, yogurt, condiment production), it is used for aeration in fermentor to avoid food pollution caused by lubricating oil leakage of traditional fan; Magnetic levitation blower can deliver clean air in the ventilation of aseptic workshop and the drying and cooling of drugs in pharmaceutical industry. Its low noise and vibration-free operation characteristics can ensure the stability of production environment and meet the requirements of GMP (good manufacturing practice). In addition, in the grain storage industry, magnetic levitation blower is used for grain ventilation and precipitation, fumigation and pest control. Its advantages of large air volume and low energy consumption can reduce storage energy consumption and avoid mildew caused by poor ventilation.

(3) Metallurgical and building materials industries

In iron and steel metallurgy industry, magnetic levitation blower is used in blast furnace blowing, converter dust removal ventilation, sintering machine ventilation and other processes. Blast furnace needs to continuously transport a large amount of high-temperature air (temperature ≤200℃). The high-temperature design of magnetic levitation blower (some models can adapt to high-temperature medium of 250℃) and high wind pressure output (up to 1.2bar) can meet the needs of blast furnace smelting, and the energy-saving characteristics can reduce the high energy consumption pressure in metallurgical industry. In the dust removal and ventilation of converter, its rapid response ability can discharge the smoke and dust produced in the smelting process in time, and ensure the workshop environment and personnel health. In the building materials industry (cement and glass production), magnetic levitation blower is used in raw material drying and ventilation, kiln cooling and ventilation and dust collection system. Its stable air output can improve the drying efficiency of raw materials, and its low maintenance characteristics can reduce the downtime of production lines and help enterprises improve their productivity.

IV. Field of New Energy and Environmental Protection Engineering

In photovoltaic, wind power and other new energy industries, magnetic levitation blowers are used for process ventilation and waste gas treatment in silicon wafer manufacturing and battery production. For example, in the process of photovoltaic silicon wafer cutting, cutting dust and harmful gases need to be discharged in time through the ventilation system, and the efficient filtration and ventilation capacity of the magnetic suspension blower can ensure the clean production environment; In the manufacture of wind power equipment, it is used for engine room cooling and ventilation, and its anti-harsh environment design (which can adapt to the temperature range of-30℃~60℃ and high altitude environment) can meet the outdoor operation requirements of wind power equipment. In addition, in garbage incineration power generation and biomass energy power generation projects, magnetic levitation blower is used for combustion-supporting ventilation of incinerator and ventilation of flue gas purification system, and its characteristics of large air volume and high wind pressure can ensure full incineration, reduce harmful gas emissions, and at the same time, the energy-saving advantage can improve the economic benefits of power generation projects.

To sum up, with its core advantages of energy saving, low noise, high efficiency and reliability, magnetic levitation blower has penetrated into many key fields such as environmental protection, municipal administration, industrial production and new energy, and has become an important equipment for optimizing production technology, reducing energy consumption and realizing green development in various industries. With the continuous upgrading and cost optimization of magnetic levitation technology, its application scenarios will be further expanded, providing power support for the high-quality development of more industries.
