Compressed air and oxygen supply dual-cooling protection system

The invention provides a compressed air and oxygen supply dual-cooling protection system, which belongs to the technical field of cooling systems. The system comprises an air inlet main pipeline, an air exhaust main pipeline, an air inlet branch pipeline, an air exhaust branch pipeline, a compressed air oxygen supply station, a noise elimination and reduction device, an air purification device, a tail gas emission sterilization and purification device, a compressed air pipe conversion pressure reduction device, a suspension hose flexible moving device, a guide rail, a protective clothing air inlet/outlet hose and a double-cooling totally-closed protective clothing. After being pressurized, the air is conveyed to the air purification device to remove toxic and harmful particles in the air, flows to the internal main pipeline through the external pipeline, and then is connected to the branch pipelines of all the wards, so that the air is conveyed into all the wards. The air in the protective clothing air inlet
