Moreover, the operation efficiency of the air compressor unit is directly related to the economic performance of the air separation system.

[0003] At present, the air compressor unit inlet is provided with air filter cotton. After long-term use, the filtering effect of the air filter cotton becomes poor, which leads to a large amount of dust entering the inside of the air compressor unit and adhering to the surface of the key components such as impeller. With the accumulation of dust, the thickness gradually increases, which seriously reduces the working efficiency of the air compressor unit. The reduction of efficiency not only affects the overall performance of the air separation system, but also may cause the air compressor unit to overload, thereby causing damage to the unit, increasing the maintenance cost and shutdown risk. In view of this, the filter core condition of the air filter cotton needs to be monitored in real time. When the air filter cotton is back purged, the dust blown down will be adsorbed on the outer wall of the filter cartridge again, which leads to a short service life of the back purge. Therefore, it is necessary to regularly stop and clean the dust. SUMMARY
