A stepwise gas distribution and graded oxygen supplementation device for distribution of high-ratio circulating flue gas is provided. The circulating flue gas distribution main pipe includes stepped sections communicated with each other in sequence, and pipe diameters of the stepped sections are reduced in sequence along a flue gas moving direction. The circulating flue gas distribution branch pipes are each in communication with and arranged at one side of the corresponding stepped section. The flue gas sealing cover is in communication with gas outlet ends of the circulating flue gas distribution branch pipes. The oxygen supplementing devices are arranged in the circulating flue gas distribution branch pipes needing to increase oxygen content. The oxygen supply device is in communication with gas inlet ends of the oxygen supplementing devices.

The present application discloses a pellet flue gas circulation and waste heat utilization process and a system thereof, which relates to the technical field of flue gas treatment. The system includes a grate, a rotary kiln, an annular cooler, and ducts connecting each part. On the basis of not changing the existing process a flue gas circulation unit and intelligent control equipment are arranged additionally in the present application. The process is simple, and not only can ensure the parameter stability of the production system such as temperature, gas flow or gas pressure, but also can make full use of the low and medium temperature flue gas components and the waste heat, so as to achieve net zero waste gas discharging, energy saving and emission reduction.
