Compressed air air separation combustion-supporting system

The invention relates to a compressed air air separation combustion-supporting system which comprises an air filter, an air compressor, an air storage tank, a drying machine, an activated carbon filter, an air buffer tank and an air separator which are sequentially connected, the air separator is provided with an oxygen outlet and a nitrogen outlet, and the oxygen outlet is further connected with a waste gas incinerator. Compared with the prior art, the compressed air is separated into O2 and N2 (including CO2 and other gases), and the O2 and N2 are respectively sent to the waste gas incinerator and other tail end gas equipment, so that the sufficient combustion effect of the waste gas can be effectively improved by high-purity oxygen, the quality of the compressed air is also improved by separation of nitrogen, the influence on a pipeline is reduced, and meanwhile, the energy consumption is reduced. The device can also be used for other air using equipment, and the utilization rate of compressed air is impro
