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.

The company requires to do a good job in summer safety production
The high temperature season is approaching, and the group company issued a notice a few days ago to make arrangements for safe production in summer. The notice requires all subordinate units of the company to attach great importance to the work of production safety in summer, and all production and business units should hold a special meeting on production safety in summer. According to the characteristics of production in summer, they should focus on safety risk analysis for mines, outdoor operations and high-temperature posts, and implement control measures to avoid the occurrence of safety accidents such as scalding, heatstroke and electric shock. In order to further strengthen the safety production management in the high temperature season, the notice requires the main person in charge of each production and business unit to lead a team to conduct a comprehensive inspection of the production and business premises according to the characteristics of summer production; strengthen the daily safety production inspection of key posts and special posts; timely rectify the found unsafe behaviors and hidden dangers; Strengthen the management of the storage and use of flammable, explosive, dangerous chemicals and drugs; cooling measures shall be taken for the space exceeding the storage temperature limit of articles. If it is found that the electrical equipment circuit and exhaust fan circuit are aged and damaged, replace them in time and keep the grounding wire in good condition. Do a good job in checking the fire pool, pipeline water pressure and fire extinguishing equipment to ensure that the fire fighting facilities are sensitive, intact and reliable. The high temperature in summer is also a period of frequent occurrence of heatstroke and other diseases. The notice requires all units to do a good job in heatstroke prevention and cooling, implement various relevant measures, and equip necessary cooling facilities or materials such as fans, air conditioners, ice cubes and other cooling facilities or materials according to the conditions of the production site; do a good job in the distribution of heatstroke prevention drugs, supplies and cool drinks in workshops, warehouses, construction sites and other production lines; strengthen canteen management to prevent food poisoning.
