2021-04-12
2021 , daye peak cement company reformed the permanent magnet direct drive frequency conversion speed regulating motor of kiln tail exhaust fan and 2 cooling tower fan. after a period of operation, the effect was obvious.
kiln tail exhaust fan was renovated, the original low-efficiency fan was removed and replaced by Halifax high-efficiency energy-saving fan; The air duct was optimized, and the inlet air duct of the tail exhaust fan was increased to reduce resistance. Remove the bypass air duct from the original desulfurization tower to the kiln tail chimney. After the transformation is completed, under the same speed, the motor current will drop to 30A , the power will drop to 400KW , and the annual power saving is expected to be 288 kwh . At the same time, Daye Peak also replaced the filter bag of the cloth bag dust collector at the end of the kiln. After the replacement, the differential pressure decreased from the original 1200-1300Pa to 800-900Pa .
Daye Peak Waste Heat Power Generation Circulating Pool has two cooling fans. The driving mode is "variable frequency motor +reducer " . This driving mode will cause problems such as oil leakage, high temperature, many faults of high-speed shaft and many transmission links of reducer. From the driving component motor to the load shaft, there is energy loss in each link, as a result, the overall efficiency is low, the system efficiency is around 75% , and the energy loss is large. After completing the transformation of permanent magnet direct drive variable frequency speed regulation motor, the motor runs smoothly, the vibration is small, and the power saving effect is obvious. The later maintenance eliminates the maintenance of the reducer. At the same speed, the current drops by 40% and the power drops by 27% after changing to the variable frequency speed regulation drive mode of permanent magnet direct drive motor.
