The utility model relates to the technical field of sintering processes, in particular to a sintering oxygen-enriched ignition combustion device which comprises an oxygen main pipe, a first oxygen pipeline, an air supply pipeline, an air-oxygen mixer and a mixed gas pipeline. The other end of the first oxygen pipeline is connected with a second oxygen pipeline through a reducing connecting pipe; a flow regulating valve, a manual stop valve, a check valve and a flame arrester are sequentially arranged on the second oxygen pipeline; the second oxygen pipeline is connected with an air inlet of the air-oxygen mixer, one end of the air supply pipeline is connected with the other air inlet of the air-oxygen mixer, an air outlet of the air-oxygen mixer is connected with the mixed gas pipeline, and the other end of the air supply pipeline is provided with an air feeder. The oxygen concentration of oxygen-enriched combustion in the sintering process is increased through the oxygen pipeline, sufficient combustion of bl
