What are the application scenarios of magnetic levitation blower?

Magnetic suspension blower is a kind of high-efficiency energy-saving blower with magnetic suspension bearing as the core technology. Compared with traditional Roots blower and centrifugal blower, it has the advantages of low energy consumption (energy saving 30%~50%), low noise (≤80dB), low maintenance cost, stable operation and so on. Its application scenarios cover many fields such as environmental protection, industrial manufacturing, municipal engineering, energy and so on, as follows:

Sewage treatment industry (core application scenario)

This is the main application field of magnetic suspension blower, which is used in aeration system of sewage treatment plant.

Working principle: continuously deliver high-pressure air to the aeration tank to promote aerobic respiration of microorganisms in the tank and decompose pollutants such as organic matter and ammonia nitrogen in sewage.

Adaptation advantages:

The air volume adjustment range is wide (30%~100%), and the aeration amount can be adjusted in real time according to the influent quality and water quantity, so as to accurately match the biochemical treatment requirements and avoid energy waste;

Contactless magnetic bearing, no mechanical wear during operation, no need for lubricating oil, no secondary pollution to sewage;

Low noise, can be directly installed in the factory area, without the need to build a separate sound insulation room, reducing infrastructure costs.

Applicable scenarios: municipal sewage treatment plants and industrial wastewater treatment stations (such as chemical, printing and dyeing, food processing wastewater treatment).

Cement building materials industry

It is used for raw meal homogenization, pulverized coal transportation and kiln tail ventilation in cement production.

Raw meal homogenization: air is blown into the homogenization warehouse to fully mix the cement raw meal particles, ensure the uniform composition and improve the clinker quality;

Pulverized coal conveying: as the power source of pneumatic conveying, the pulverized coal is stably conveyed to the cement kiln to ensure combustion efficiency;

Adaptability advantages: high temperature resistance, dust resistance, long-term stable operation in harsh industrial environment; Frequency conversion speed regulation characteristics can accurately match the changes of kiln working conditions and reduce energy consumption per ton of cement.

chemical lines

Suitable for gas transportation, oxygen supply by fermentation, tail gas treatment and other processes in chemical production.

Gas transportation: transporting inert or process gases such as nitrogen, oxygen and carbon dioxide for chemical synthesis and material protection;

Oxygen supply for fermentation: provide sterile air for biochemical fermentation tanks and support aerobic fermentation of strains (such as the production of amino acids and antibiotics);

Tail gas treatment: provide combustion-supporting air for RTO (regenerative thermal incinerator) and RCO (regenerative catalytic combustion equipment), or extract chemical tail gas for centralized treatment;

Advantages of adaptation: oil-free lubrication design ensures the purity of conveying gas and avoids polluting process materials; The operation stability is high, which can meet the requirements of 24-hour continuous operation of chemical production.

Electric energy industry

Thermal power generation: used in desulfurization and denitrification system of power plant, which blows air into the absorption tower to promote the reaction between desulfurizer and sulfur dioxide and improve desulfurization efficiency;

Biomass power generation: provide gasification wind for biomass gasifier, ensure full gasification of biomass raw materials, and produce high-quality gas;

Power generation by garbage incineration: the aeration system used for garbage leachate treatment and the secondary combustion-supporting air transportation of the incinerator reduce pollutant discharge.

Metallurgical industry

Used in blast furnace blast, converter dust removal, sintering flue gas treatment and other links in the smelting process of steel and nonferrous metals.

Blast blast: provide high-pressure air for blast furnace ironmaking, promote coke combustion and iron ore reduction, and the high pressure and wide adjustment characteristics of magnetic suspension blower can adapt to the air demand of blast furnace in different smelting stages;

Flue gas treatment: provide power wind for metallurgical flue gas desulfurization and denitrification system to help meet the discharge standards;

Adaptability advantages: strong corrosion resistance (anti-corrosion coated impeller can be selected), which can adapt to the acidic medium in metallurgical flue gas; Compact structure, small floor space, suitable for dense equipment layout in metallurgical plant area.

Municipal and civil fields

Urban centralized gas supply: used for pressurized transportation of natural gas and liquefied gas to ensure the stability of gas pressure for residents and commercial users;

Ventilation of underground garage: instead of traditional axial flow fan, it provides efficient ventilation for underground garage, discharges automobile exhaust, and reduces running noise and energy consumption;

Aquaculture: An oxygen-increasing system used for industrialized aquaculture, which delivers air to the aquaculture pond, improves the dissolved oxygen in water, promotes the growth of fish and shrimp, and reduces the occurrence of diseases.

Paper industry

Used in pulp aeration, black liquor treatment, waste paper deinking and other links in papermaking process.

Pulp aeration: blowing air into the pulp pool to promote the separation of impurities in pulp and improve the quality of paper;

Black liquor treatment: provide aeration wind for the anaerobic-aerobic treatment system of papermaking black liquor to degrade organic pollutants in black liquor;

Advantages of adaptation: stable operation, no pipeline rupture caused by vibration, and avoiding pulp leakage; Oil-free design, prevent oil pollution of paper pulp, and ensure paper hygiene and safety.

Summary of application advantages

The core competitiveness of magnetic levitation blower lies in high efficiency, energy saving and low maintenance cost, which is especially suitable for scenes that need long-term continuous operation, frequent air volume adjustment and high environmental protection requirements. With the promotion of the "double carbon" policy, its replacement space in high energy-consuming industries will continue to expand.
