Practical experience of energy-saving transformation for the air compressor station of a steel factory
YIN Jianchuan
Abstract：To address the frequent equipment failures,high energy consumption and non-compliance with environmental standards caused by the ineffective oil mist treatment in the air compressor station of a steel factory,a study is conducted on 23 third-level centrifugal air compressors in a steel factory.Through on-site investigation,technical comparative analysis and phased implementation of renovations,the inherent design problems of the equipment,the chain effects of filter element failure and the secondary problems of temporary measures are analyzed,and the'venturi vacuum jet+efficient filtration recovery'scheme is selected for renovation.The results show that after the renovation,the annual oil replenishment volume of the air compressors significantly decreased,the temperature of the motor bearings dropped from 85℃to 65℃,the lifespan of the air filter elements is significantly prolonged,and the concentration of oil mist emissions is greatly reduced.The practice has proved that the renovation scheme effectively solved the current operation problems of the air compressors.
