Remove the dust accumulation on the blades and impellers of the vertical mill circulating fan
During the high-temperature production process, dust is prone to accumulate, and over time, the fan will vibrate and shut down. Clear the dust accumulation on the blades and impellers of the high-temperature fan, solve the vibration of the fan caused by the imbalance of the fan rotor. There is no need to stop the machine for cleaning, break the lumps, remove the dust accumulation on the cement impeller and the inner shell of the fan, and the fan can operate normally. No manual shutdown is required for air duct treatment, which affects production efficiency.
During the operation of induced draft fans in cement plants, dust, particles, and other materials are prone to accumulate on the fan impeller, casing, and other parts, forming "scaling". This kind of accumulation can lead to the following problems:
Equipment failure riskThe accumulation of materials disrupts the dynamic balance of the fan, causing severe vibrations that may lead to bearing damage, impeller deformation, and even fan shutdown.
Production interruption lossesUnscheduled shutdowns can interrupt the continuous operation of cement production lines, resulting in waste of raw materials, loss of production capacity, and increased maintenance costs.
Rising maintenance costsFrequent cleaning of accumulated materials requires manual shutdown, which is time-consuming and labor-intensive, and may shorten the service life of the fan.
The acoustic dust collector emits specific frequency sound waves (such as low-frequency high-energy sound waves) to form periodic pressure fluctuations inside the fan. Its working principle and advantages are as follows:
Anti accumulation mechanismSound wave vibration causes dust particles attached to the surface of the fan to resonate, breaking their adhesion to the equipment surface and promoting the material to be discharged with the airflow, avoiding accumulation.
Non contact cleaningNo need for shutdown or manual intervention, it can continue to work during the operation of the fan without affecting the production process.
| Application scenarios |
Pre installation issues |
Improvement effect after installation |
| Cleaning of induced draft fan in cement plant |
Material accumulation leads to 1-2 unplanned shutdowns per month |
Unplanned downtime elimination, only requires planned maintenance |
| Wind turbine maintenance frequency |
Temporary shutdowns are required 2-3 times a month for cleaning |
Maintenance is only carried out during annual/quarterly scheduled maintenance |
| Production efficiency impact |
A single shutdown resulted in an 8-hour loss of production capacity (approximately 500 tons of cement) |
No production capacity loss throughout the year, equipment utilization rate increased by 15% |
Ensure production continuityFrom "passive response to shutdown" to "active prevention of accumulation", to avoid production interruptions caused by equipment failures, especially suitable for continuous production industries such as cement and metallurgy.
Reduce maintenance costsReducing the frequency of manual cleaning and the need for component replacement, according to industry data statistics, can reduce fan maintenance costs by 30% -50%.
Improve equipment lifespanEliminate damage to the fan caused by abnormal working conditions such as vibration, and extend the service life of core components such as impellers and bearings.
Intelligent integrationIt can be linked with the factory DCS (distributed control system) to automatically adjust the frequency of sound waves based on parameters such as dust concentration and operating time, achieving precise cleaning.
In addition to the induced draft fan in cement plants, acoustic dust collectors can also be used for:
Cleaning of heating surface of power plant boilerPrevent the accumulation of coal ash from affecting thermal efficiency.
Grain storage dust removalClear the dust accumulation inside the silo and reduce the risk of dust explosion.
Chemical pipeline anti scalingAvoid material adhesion and blockage in the powder conveying pipeline.
The core value of "eliminating unplanned downtime" in the case essentially reflects the transformation of industrial maintenance concepts: through preventive technologies such as acoustic dust removal, enterprises can upgrade from "post repair" mode to "pre prevention", which is not only an optimization of equipment management, but also a key breakthrough in production efficiency and cost control. For fan equipment in high dust environments, this type of technology is worth promoting as a standard solution.
