The invention discloses a sintering oxygen-enriched supply system with double oxygen supply pipelines and an oxygen supply method. The system comprises an air supply device, a first oxygen supply device, a second oxygen supply device and a mixer, the first oxygen supply device and the second oxygen supply device communicate with a first oxygen pipeline and a second oxygen pipeline correspondingly, the mixer communicates with an oxygen branch pipeline, the first oxygen pipeline and the second oxygen pipeline respectively communicate with the oxygen branch pipeline, the first oxygen pipeline and the second oxygen pipeline are provided with a first oxygen flow adjusting valve and a second oxygen flow adjusting valve correspondingly, the oxygen branch pipeline is provided with a total oxygen flow meter, a second oxygen flow meter is arranged between the second oxygen flow adjusting valve and the second oxygen supply device, and the ratio of the oxygen flow value of the first oxygen pipeline to the oxygen flow value of the second oxygen pipeline is 8-10; The oxygen supply method comprises coarse adjustment and fine adjustment. Compared with the prior art, the system and the method aim to overcome the defect that in the prior art, oxygen adjusting precision is low.
Description
technical field [0001] The invention relates to the technical field of oxygen-enriched combustion, in particular to a sintered oxygen-enriched system and an oxygen supply method with dual oxygen supply pipes. Background technique [0002] Surface ignition is a process in which the surface of the mixture on the sintering machine trolley is heated to about 1050°C with a burner in the ignition furnace, and the coke on the surface of the fuel layer is ignited to form a combustion zone with a certain thickness on the surface of the mixture. Oxygen-enriched ignition is an auxiliary ignition process in which a certain proportion of pure oxygen is introduced into the combustion-supporting air pipeline of the ignition furnace to increase the oxygen content of the combustion-supporting air in the ignition furnace, improve the combustion temperature of low calorific value fuels, and strengthen the ignition effect of the material surface. [0003] The oxygen concentration has a great in...
