According to the invention, the air flows of the air compressor 1 and the dust suction fan 14 are led into the cleaning area through the air suction pipe 15 and the air guide pipe 9, so that the occupied space is small, personnel are not required to enter in the dust cleaning process, the narrow space can be cleaned, the situation that the personnel touch components such as optical fibers, a board card, a cooling water pipe and the like by mistake is prevented, and the potential safety hazard is reduced. The high-voltage generator 12 is combined with the air compressor 1, and when the air compressor 1 ejects gas through the gas guide pipe 9, the high-voltage generator 12 can generate high-voltage discharge through the electrode 8, so that the ejected gas has positive and negative ions, and the dust cleaning efficiency is greatly improved. The dust suction fan 14 can absorb dust in the process of sucking the dust, so that the dust is prevented from polluting other areas. The drying agent 5 can filter moisture in the gas in the process of passing the compressed gas, so that equipment corrosion caused by excessive moisture is avoided.
