What are the characteristics of installing magnetic levitation blower in chemical field?

The magnetic suspension blower used in chemical industry is characterized by remarkable energy saving, oil-free cleanliness, intelligent controllability, low maintenance and adaptability to extreme working conditions, which is especially suitable for continuous, large-flow and high-precision air supply process scenes.

First, high efficiency and energy saving (chemical high energy consumption is just needed)

Energy saving is 30%-50% compared with Roots blower and 15%-25% compared with ordinary centrifugal blower.

No mechanical friction (magnetic bearing)+high-speed permanent magnet motor (efficiency ≥96%)+ three-dimensional flow impeller, and the efficiency of the whole machine reaches IE5/IE6 level.

The air volume is 30%-100% stepless adjustable, which accurately matches the variable load conditions such as reaction kettle, desulfurization and oxidation, and avoids "big horse-drawn car".

Chemical industry runs continuously (8000h+ per year), and the investment can be recovered in 1-3 years.

Second, clean without oil, put an end to medium pollution.

There is no lubricating oil system, and the conveying air is absolutely free of oil, water and impurities.

Suitable for fine chemicals, pharmaceuticals, fermentation, electronic chemicals and other processes that prohibit oil pollution.

It can be used for conveying corrosive gases (such as Cl, SO, NH), and can be equipped with stainless steel impeller/anticorrosion volute.

Third, intelligent and precise control, adapting to complex chemical processes

Seamless connection with DCS/PLC, closed-loop automatic adjustment according to dissolved oxygen, pressure, pH, temperature and other parameters.

The adjustment accuracy is within * * 3% * *, the air volume/pressure is stable without pulse, and the oxidation rate can reach 95%+.

Five-degree-of-freedom magnetic bearing, monitoring ten thousand times per second, the rotor is always suspended, with minimal vibration and stable operation.

Remote monitoring, fault early warning, unattended, reducing on-site labor.

4. Low maintenance and long service life, suitable for continuous chemical production.

No mechanical wear, no bearing replacement, no lubricating oil replacement, only the air filter needs to be replaced daily.

The design life is 20 years+,which is much longer than that of traditional fans (5-8 years).

Integrated skid mounting, small size, light weight, simple installation and no need for large foundation.

The noise is 75–80 dB (A), much lower than that of Roots blower (110–120 dB), which improves the factory environment.

Fifth, strong adaptability to extreme working conditions

Temperature: it can withstand **-30℃ to 780℃** (high temperature type), and is suitable for chemical high-temperature flue gas and thermal oxidation process.

Pressure: 0.5–2.5 bar (g), meeting the pressure requirements of desulfurization, oxidation and pneumatic conveying.

Environment: IP55 protection, dust-proof, moisture-proof and corrosion-proof, suitable for wet/corrosive chemical workshops.

Six, typical chemical application scenarios

Ammonia desulfurization: instead of roots blower, energy saving is 30%+, and oxidation is more complete.

Aeration of reaction kettle: accurately control the wind and adapt to the whole stage of heating/reaction/cooling.

Powder transportation: low-pressure pneumatic transportation of PVC, resin and fertilizer particles.

Wastewater biochemistry: aerobic tank aeration, energy saving+low noise+maintenance-free.

Seven, compared with the traditional fan (chemical perspective)

Energy saving: magnetic levitation 30%-50%; Roots/centrifugal reference.

Cleanliness: magnetic levitation oil-free; Roots/Centrifuge has the risk of oil mist pollution.

Maintenance: magnetic levitation changes the filter element every year; Roots/Centrifuge should change oil every month and bearings regularly.

Noise: magnetic levitation 75–80dB; Roots 110–120 db.

Life: magnetic levitation for 20 years+; Roots/Centrifuge 5–8 years.

summarize

Under the background of "double carbon+environmental protection+cost reduction" in chemical industry, magnetic levitation blower is the preferred power equipment with energy saving, cleanliness, intelligence and maintenance-free, especially suitable for high energy consumption and continuous processes such as desulfurization, reaction kettle, powder conveying and biochemical aeration.
