A device for low-load operation of an air separation plant belongs to the technical field of cryogenic oxygen producing equipment and is used for low-load production of the air separation plant. The technical scheme adopted is that the device comprises more than two small air compressors and supporting valves, each small air compressor is provided with a check valve and an outlet valve in sequential connection; all the outlet valves are connected through pipelines with outlet valves respectively mounted therein; the outlet valve of one small air compressor is connected with another outlet valve and the air separation plant through the pipeline; and a pipe connection bleeding valve is arranged on the connecting pipeline of each small air compressor and the corresponding check valve. According to the utility model, the plurality of small air compressors are used for production, rather than the large air compressor body; the small air compressors can be reversed for air separation low-load production without air
